rlhe present invention relates to metalworking generally and more particularly to apparatus for forming circumferential ribs or runners on steel barrels or the like.
An object oi the present invention is to provide a novel metalworking apparatus for forming circumferential ribs or runners on the sides of steel barrels or other similar cylindrical metal containers.
Another object of the invention is to provide a novel sheet metalworking apparatus for forming outwardly projecting ribs or runners on the sides of steel barrels or the like which are thicker at ltheir outermost portions than the initial sheet.
further object is to provide a novel metal working machine for forming circumferential runners on a metal cylinder or the like, having a reciprocally movable ram thereon supporting a series of radially arranged expander shoes which are mounted. for motion in an inclined plane and which cooperate with a cam surface to move outwardly to engage with the internal walls of the cylinder coincidentally with a telescoping force applied to the ends of the cylinder by the ram to form circumerentially channeled runners thereon without appreciable reduction of thickness which usually occurs in expanding operations.
Another object is to provide a novel metalworking machine for compressing the outer ends oi circumferential ribs or runners formed on the side walls or a metal cylinder or the like, to provide a greater thickness of metal at the outer ends of the runners than at the side walls of the cylinder, the machine having a roller for engaging with the outer end of each rib or runner which is movable toward the cylinder to compress the metal it engages inwardly at the apices of the ribs or runners.
A still further object of the present invention is to provide an apparatus for constructing a stainless steel barrel or the like from a single sheet of metal which is formed into a cylinder having a uniform thickness throughout which consists in forming extending ribs on the sheet which are integral with the latter and of the same thickness and for thereafter compressing the outer ends of the ribs inwardly to provide a greater thickness of material thereat than at the side Walls of the cylinder.
Other objects and advantages of the invention will become apparent from the following speciication, the accompanying drawings and the appended claims.

Fig. 6 is an enlarged View in section of that portion of the structure located within broken circular line 6 o1" Fig. 5; and
Fig is a view taken substantially along the line l-l of Fig, 5.
Referring now to the drawings for a more detailed description of the present invention and more particularly to Fig. 1 thereof, the novel runner forming machine or press hereof is shown as generally comprising a bed member lil and a crown member li, the two being spaced apart and secured together by virtue of side rails i2 and i3. suitably supported by crown member Il, at a substantially central portion thereof is a power cylinder I4 having a piston l5 mounted for re ciprocal movement therein, the interior of the cylinder communicating by way of conduits i and il with a more suitable source of iiuid pressure (not shown) such as vacuum, hydraulic or pneumatic pressure, and, depending upon the power used, one of conduits l5, il will act as an inlet and the other as an outlet.
A piston rod t8 is connected at one of its ends with piston l5 tor movement thereby and at its other end is connected to a ram i9 which is movable along side rails l2 and i3 by the piston. A punch holder Z is supported at the underside and centrally of ram I9 and has a substantially annular hollow swaging ring 2l secured thereto by way of bolts 22, the latter passing through an outwardly extending iiange 23 formed on the inner end oi the ring. The upper end of bed member lil has a die-shoe member it rigidly tened thereto by suitable means (not shown) which supports thereon a second hollow swagng ring 25 similar to ring 2l having an outwardly extending iiange 25 formed at its inner end, bolts 2l (Fig. 2) passing through flange 2t to secure ring 215 to die-shoe member 24.
As more clearly shown in Fig. 2, the underside of punch holder 20 carries thereon internally of swaging ring 2 i, a punch member, generally des* ignated with the reference character 218, having an outwardly extending iiange portion 29 at its inner end, an intermediate reduced cylindrical portion 30 and two adjoining members, the inner one of which is provided with an inclined cam surface 3l and the outer one of which is provided with an inclined cam surface 32, the slope of the former cam surface being substantially greater than the slope of the latter cam surface. ln a similar manner, the top of die-shoe member 2d carries a punch member thereon, generally designated with the reference character 33, internally of swaging ring 25, the punch member having an outwardly extending flange portion i at its inner end, an intermediate reduced cylindrical portion 3E, and two adjoining members, the inner one of which is provided with an inclined cam surface 3S and the outer one or" which is provided with an inclined cam surface 3l, the slope of the former cam surface being substantially greater than the slope of the latter cam surface.
In addition to carrying swaging ring 2l and punch member 2S, punch holder i@ also supports at its underside an expander shoe assembly, gen erally designated with the reference character 35, such assembly comprising (as better shown in Fig. 2) upper and lower spaced retainer rings 39 and ill which are arranged intermediate swaging ring 2l and punch member 28 and swaging ring and punch member 33, respectively. Upper ring 39 is formed with a series of bores il and aligned and enlarged counterbores l2 (one bore and one counterbore only being shown in Fig. 2) the inner face of each counterbore acting as a stop or a supporting shoulder :for the enlarged head 3 of a shouldered bolt having a re duced intermediate shank dii and a further reduced threaded section da which cooperates with its related -internally threaded bore formed in iiange 29 of punch member 28. By reason of the foregoing arrangement expander shoe assembly 38 is carried by and movable with punch holder 2li which, in turn, is operated by ram i9, and since v heads i3 of the shoulder bolts are confined within counterbores d2, ring 39 as well as the remainder of the expander shoe assembly is adapted for limited motion relative to punch holder 2c ior a purpose to appear hereinafter. inner or lower face of ring 59 is formed with an inclined surface l for a purpose to also presently appear.
1n a similar manner, lower retainer ring 1li) is formed with an inner or upper inclined face or surface il and near its outer periphery is formed with a series of bores 53 and aligned counterbores 49, each pair of bores being axially aligned with a bore ed formed in retainer ring 3S. rIie rods 5! pass through each set of aligned bores 5&8, le and 5c whose enlarged heads 52 rest on the upper surface of ring 3d and whose lower ends are threaded to receive nuts Eil thereon. Coil springs 54 are sleeved on the lower ends of the tie rods with one end of each spring engaging the shoulder defined by the inner face of each counterbore i9 and the other end of each spring engaging a washer element 5E supported on nuts 53.
In addition to rings 39 and lill, assembly 38 also includes a series of radially arranged upper and lower substantially rectangular expander shoes 5% and 5l whose outer end walls engage, respectively, with the inclined inner surfaces d and il of rings 39 and lli). The inner walls of expander shoes `58 and lil, on the other hand,
d engage with the inclined outer walls of a series of radially arranged center shoes 5.8 and 5, respectively. The inner walls of center shoes 58 and 5S are level and normally in engagement as shown in Fig. 2.
In their ineffective position, i. e., one immediately preceding rib or runner pressing operation, expander shoes 56 and 5l and center shoes 58, 59 are located relative to each other and to the internal wall of a metal cylinder 5S, in which the ribs o1' runners are to be formed, in a manner substantially as shown in Fig. 2. Center shoes 58, 59 are each provided with enlarged or aligned bores 6l and 62 adjacent their outer ends through which a related tie rod 5l passes, the bores 6l and E2 being of such nature as to permit limited outward motion of the center shoes relative to the tie rods against thel action of garter springs B3 and lill which rest within a series of arcuate and aligned recesses 6'5 and Sli formed substantially at the inner ends of shoes 53 and 59, respectively. Garter springs 63 and lill normally maintain the center shoes 58 and 59 in a retracted position shown in Fig. 2 wherein an upper portion of an inner inclined end of cam surface el of each shoe 58 engages a lower portion of cam surface 32 of punch member 28 and wherein a portion of an inner inclined side of cam surface 68 of each shoe 59 engages a portion of cam surface 3l of punch member 33.
The outward end of cam surface El of each center shoe 53 terminates in a more sharply inclined relief surface te a portion of which defines one end of a rectangular slot le formed in each of the center shoes at the outer inclined wall thereof adjacent the lower engaging surface of expander shoes Eli. Each slot lli so formed receives a coil sp1-ing 'il therein, one end of each spring abutting the shoulder defined by the inner end of each slot and the opposite end of each spring abutting with shoulder portion 1.2 of a stud 'F3 supported within a bore lil formed in each of expander shoes 56. By virtue of the foregoing arrangement, as garter spring 63 retracts center shoes 5S to their innermost position, under conditions to be presently described, springs 'll are compressed to thereby urge expander shoes 56 inwardly by way or" studs 'i3 engaged by the springs, each expander shoe 'c6 being provided adjacent its outer end with a slot l5 surrounding each tie rod 5l to accommodate motion of each expander shoe relative to the tie rods. As will be apparent from the drawings, slots l5 are larger than slots Gl of the center shoes since the expander shoes must travel downwardly and outwardly a greater amount than the outward travel of the center shoes.
In a generally similar manner the outward end of cam surface 68 of each of center shoes lill terminates in a more sharply inclined relief surface 16, a portion of which defines one end of a substantially rectangular slot il formed in each of the latter' shoes at the outer inclined wall thereof adjacent the upper engaging surface of expander shoes 5l'. Each slot ll defines a receptive chamber having a coil spring lil, one end of each spring abutting the shoulder dened by the inner end of each slot and the opposite end of each spring abutting with shouldered portion l0 of a pin 80 supported within a bore #8l formed in each of expander shoes 5l. As garter spring 64 draws center shoes 59 to their innermost or retracted position, springs 'I8 are compressed to thereby urge expander shoes 51 inwardly by way of pins engaged by the springs, each expander shoe 5l being provided adjacent its outer end with a slot 82 surrounding each of tie rods 5| to accommodate motion of each of the latter expander shoes relative to the tie rods. Slots 82 are of the same size as slots 'l5 of expander shoes 56 since expander shoes 5l move upwardly and outwardly an amount exceeding the amount of outward lmovement by center shoes 59.
lThe innermost end of each expander shoe 5t is provided with an inclined or cam surface S3 for cooperation with cam surface 3| of punch member 252, surface 83 terminating in a more sharply inclined relief surface 84, while the inner end of each expander shoe 57 is provided with an inclined or cam surface 85 for cooperation with cam surface 3S of punch member 33, surface 35 terminating in a more sharply inclined. relief surface 8S. The outward ends of expander shoes 55 are provided with a spaced and downwardly inclined upper surface 8l, a curved pressing end surface El? and a downwardly inclined surface better shown in the right hand side of Fig. 2, while the outward ends of expander shoes El are provided with a spaced and downwardly inclined upper surface 99, more sharply inclined than surface 8'! of shoe 56, an intermediate curved pressing end surface 9| and a downwardly inclined surface 92 whose slope is somewhat smaller than that of surface S9 of shoes 5t.
Swaging ring 25, whose width exceeds the width of swaging ring 2|, is provided internally at its upper end with a circular groove or recess S3 whcse side wall conforms generally with the configuration of a portion oi the pressing end surface 9| and downwardly inclined surface 92 of each of expander shoes 5l. In a similar mann ner, swaging ring 2l is provided internally at its lower end with a circular groove or recess 9d whose sidewall conforms generally with the shape of a portion or" the pressing end surface 8S and downwardly inclined surface 8l of each of expander shoes 5G.
.In order that expander shoes 51 and center shoes 59 may not move outwardly preceding the time that expander shoes 56 and center shoes will begin to move outwardly, a supporting arrangement is provided to prevent such premature action, such arrangement including an annular floating supporting plate 95 which is provided with a series of spaced apertures for receiving therein bolts 96. The lower ends of bolts sii are threaded for cooperation with a series of spaced threaded bores 91 formed within flange 3d of punch member 33, the bolts being adjustable downwardly or upwardly as required relative to the retainer ring 4l) by way of nuts The upper portion of each bolt d'6 is provided with enlarged head 99, and the heads of the bolts cooperate with a series of radially spaced bores lo@ formed at the bottom of rering fill. Coil springs 19| surround the bolts 95 with one end of each spring abutting respective one of the nuts 98 and the other end of each spring resting within a recess E02 formed on the underside of plate 95. rlhus, plate liti is yieldably urged in an upward direction by way of spring fi I.
Initially, ram i9 is in its upward or retracted 'position with swaging ring 2|, expander shoe assembly 38 and punch member 28 held thereby away from lower swaging ring 25. At this point cylinder member et is placed in swaging ring 25 with its bottom end resting at substantially the junction point of recess Sil-and a slightly inwardly inclined wall IBS of the ring, the lower end of which terminates in a shoulder Hit, the remainder or the hollow ring being of a reduced diameter as shown in Fig. 2. With cylinder 6@ supported in an upright position within ring 25, piston l5 is actuated to lower ram i9 together with the various operating mechanisms supm ported thereby. As upper swaging ring 2i approaches cylinder 60, the top end of the latter will initially engage with the interior of the ring at the junction of recess 94 and the slightly inwardly inclined wall |95 of the ring, the latter terminating in a shoulder |05, the remainder of the ring being of a reduced diameter as shown in Fig. 2. As cylinder 60 is engaged by swaging ring 2|, the punch member 28 together with the expander shoe assembly 33 will have been lowered within cylinder 60 substantially as shown in Fig. 1.
By reason of its own weight, expander shoe assembly 38 will be supported by punch holder 29 through the engagement of the enlarged heads d3 of bolts Ml with the inner shoulder or face oi counterbore 42 of ring 2|. Since lower slices 5l and 59 would engage cam surfaces Sii and 3l prior to engagement of upper shoes 55 and 53 with their related cam surfaces 3| and t2, floating plate 95 is provided to support the weight of the shoe assembly and thereby prevent expansion of the lower shoes prior to the time that the upper shoes will expand, it being important that outward expansion of the shoes occur at substantially the same time. Continuing downward motion of ram i9 subjects the top and bottom ends of cylinder t0 to a swaginfT operation so that the cylinder at its outer ends is formed with walls having gradually reduced diameters, such swaging operation continuing until the bottom and top cylinder ends engage with shoulders Idil and |05, respectively, of both swaging rings.
As the outer ends of cylinder 5t engage with shoulders EM and |96, the outer and pressing faces of expander shoes 56 and 51 and center shoes 5S and 59 will assume a position, relative to the internal walls of cylinder 60, as shown in Fig. At the same time there will be some relative motion between punch holder El) and expander assembly 38 until bolts d are driven within their bores 42 to a position where flange 2i) of punch member 28 engages the upper end of retainer ring 39. Thereafter', the punch member is moved downwardly towards punch member 33, cam surface 3| engaging with cam surface $3 of expander shoes 5t to move the latter downwardly and outwardly against a wall of cylinder t9, and simultaneously therewith cam surface 32 coopcrates with cam surfaces 67 ci center shoes 5s to drive the latter outwardly against the action of garter spring tt. At the same time, cam surface Sl cooperates with cam surface 5S of center shoes E9 to drive the latter outwardly against the action of garter spring Sii and cam surface 35 cooperates with cam surface of lower expander shoes 5l to drive the latter upwardly and outwardly. As outward movement of the various expander shoes takes place, swaging ring 2| continues its downward motion so that as expander shoes d5 and 5l' have been driven outwardly their maximum amount (as illustrated in 3) the upper portion of a rib or runner itl formed on the cylinder by the expander shoes will be urged by expander shoes 5S into engagement with internal recess 94 of swag-ing ring 2| and a lower portion 5 of a rib or runner IS formed on the cylinder will be urged by expander shoes l into engagement with internal recess 93 of swaging ring 25. In addition to swaging the ends of cylinder G, rings 2| and 25 also help to sharpen the corners of the ribs or runners, a wall of the cylinder intermediate the runners being pressed outwardly as shown in Fig. 3, by center shoes 58 and 5S.
As the cylinder walls ultimately formed into runners itl and Hi8, are pressed outwardly, the cylinder is compressed inwardly lengthwise so that the nnal length of the cylinder is substantially less than its original length and as a result of such compression metal is caused to dow in the cylinder walls at the inclined surfaces Sil and 90 and 8l and 92 of expander shoes 56 and 5l so that desired sharp corners on the runners are obtained, the walls of the runners having substantially the same thickness as the remaining walls of the cylinder. By providing the upper expander shoes with downward and outward motion and the lower expander shoes with upward and outward motion, at the same time as pressure is applied by rings 25 and 2| coming together forcibly stretching of the metal of the cylinder walls is prevented which would otherwise occur if the shoes were expanded outwardly only and the squeeze were not coincidentally applied. Center shoes 53 and 5, on the other hand, provide a straight wall between the runners, such wall in the absence of the center shoes, otherwise assuming an undesirable curved form.
Subsequent to completion of the pressing operation whereby runners ||ll and |63 are formed on cylinder St, piston l5 is actuated to retract rain lil and withdraw swaging ring 2| and punch member 28 from cylinder S6, expander shoe assembly 33 remaining in substantially the position of Fig. 3 until the enlarged heads i3 of bolts @il engage with the inner faces of counterbores l2 to lift the expander shoe assembly. As cam surfaces 3| and 32 of punch member 2S move upwardly relative to expander shoes 56 and center shoes 58, garter spring 63 contracts to retract shoes EES whereupon expander shoes 5E are likewise retracted by way of springs '1| and studs i3. During the same interval, expander shoes 5l and center shoes t move upwardly relative to cam surfaces 35 and 3l so that garter spring @d contracts to retract center shoes 59 whereupon the latter, by way of springs 'i8 and pins Eil, retract expander shoes 5l. As the expander shoe assembly 3S clears cylinder Eil, the latter may be removed and a plain straight walled cylinder is again inserted within swaging ring 25 and the rib or runner forming and pressing operation is repeated.
While expander shoe assembly 38 has been shown as supported by the punch holder for movement therewith through the agency of the shoulder bolts it is to be understood that the expander shoe assembly may be supported by the die shoe 21| in which event the assembly wouldbe arranged. within the swaging ring 25 and secured by suitable means such as bolts, for example, to floating pad or plate 95.
Cylinder 6c with the runners lill' and Hi8 formed thereon is removed from the press and thereafter mounted on a novel rolling machine whereby the outer ends of the runners are rolled and compressed inwardly to provide a greater amount of metal at the outer ends of the runners from that present in the walls of the cylinder. vThe rolling machine, as more clearly shown in Fig. 7, comprises a table or platform |09 supported on a bed plate H0 by way of spaced supporting members ill and ||2. Table lill) is centrally recessed to receive and support therein a hollow bearing housing IIS whose bottom end plate lll is fastened to one end of a hollow tubular shaft H5, the other end of the latter being connected to top plate H6 of a gear housing i il supporting bearings itil therein, which journal the lower end of a hollow spindle i9, the upper end of the spindle being journaled within bearings |2|J supported within housing H3.
The bottom end of spindle HS is jcurnaled within a bearing |2| carried by the gear housing and has a reduced threaded portion engaged by a lock nut |22 maintaining a worm wheel or gear |23 thereon, the latter being fastened to the reduced end of the spindle by way of splines it. Worm wheel or gear |23 is in mesh with a worm |23a (Fig. 5) carried by a shaft |25 suppor ig a pulley |26 thereon, the latter being driven through a belt drive by a motor (not shown) in a conventional manner. Operation of the motor will therefore result in rotation of spindle H9 for a purpose to presently appear.
Spindle H9 is generally conical in shape and at its top end has an extending flange or plate |21 formed integrally therewith, the underside of the plate bearing within a shouldered recess formed at the top of housing |13. Secured to plate l2? for rotation with spindle ll@ by way of bolts |23 is a chuck |29 provided with a central opening i3d and having a series of radial recesses |3| and |32 formed therein. Eecesses |3| slidably receive therein a series of dially expanding jaws |253 having their inner ei fastened to plungers i3d whose free ends carry inclined or cam surfaces |35 for cooperation w` h a cam member |35 having an inclined surta@ (3l. Recesses |32, on the other hand, slidably receive ther in a series of radially expanding jaws |38 having their inner ends fastened to plungers |39 whose free or inner ends carry inclined or cam surfaces ilill for cooperation with a cam member lill having an inclined surface |62, earn member |13! being spaced from cam member |36 and both members being secured to a draw bar or rod M3 by way of keys lai-i and it, respectively. Draw bar or rod it@ is telescopically mounted within spindle H9 for a purpose to presently appear.
The outer ends of expanding jaws |33 are provided with upper and lower curved surfaces for engaging the inner side walls of rib or runner lill of cylinder et, such surfaces terminating at their inner ends in grooves uit which denne receptive chambers for a return or garter spring lill which is annular in form and which urges jaws |33 in an inward direction when cam member |36 has been raised upwardly relative to inclined surfaces |35 of plungers i3d. ln a generally similar manner, the outer ends of expanding jaws |38 are provided with upper and lower curved surfaces for engaging the inner side walls of ribs or runners |83 of cylinder Sil, the latter surfaces terminating at their inner ends in grooves |48 which define receptive chambers having a return or garter spring it which is annular in form and which urges jaws 38 in an inward or retracted position when cam member |48 has been raised upwardly relative to inclined surfaces It@ of plungers |39.
The upper portion of chuck |29! has a series of spaced radial recesses I formed therein slid- `ably receiving plungers |5| which carry retainer jaws |52 at their outer ends for engaging with the top end of cylinder 60 and thereby maintaining the cylinder on the chuck, the bottom of the cylinder being maintained in engagement with a supporting shoulder |58 of a ring |54 which is fastened by way of screws |55 to the side wall of the chuck. Plungers at their inner ends are formed with inclined surfaces |58 for cooperation with cam surfaces |91 of a cam member |59 secured by way of a key |59 to the top of draw bar or rod |49, Retainer jaws |52 at their outer ends are provided with grooves |69 which receive a return or garter spring |55, the latter urging the retainer jaws inwardly to disengage from the top of cylinder tt when cam |59 has been moved upwardly. rlhe opening at the top of chuck 29 may be closed by a suitable dust cover |62, the latter being large enough to accommodate the required upward motion of draw bar |43 therein.
The bottom end of draw bar |43 supports a bearing housing |63 thereon having a circumferential groove |94 formed therein with which cooperates a pin |65 carried by a yoke member 66 supported at one end of a lever |61, the lever being pivotally mounted at a substantially central portion thereof on t e spaced arms of a bracket |68 by way of a pin |89. The opposite end of lever iti is connected by way of a pin |13 with a piston rod carrying a piston thereon (not shown) which is reciprocally movable within a cylinder |12. The cylinder, in turn, carries spaced arms |13 and |14 thereon which pivotally mount the cylinder by way of a pin on a bracket IE5 fastened by way of bolts |11 to side member H2.
At the same time that cylinder 60 is inserted on chuck |29, draw bar |43 will have been moved upwardly by piston rod |1| so that cam members |39, |57 and |59 will have been moved upwardly relative to plungers |34, |49 and I5| so that garter springs |41, I 49 and |6| will have drawn the expanding and retainer jaws inwardly so that the cylinder will clear the latter as the bottom of the cylinder is brought to rest on shoulder |53 of ring |54. In this assembled condition the grooves |45 of jaws |33 and grooves |48 of jaws |38 are substantially aligned with the apices of runners |91 and |88, respectively.
As draw bar |43 is actuated downwardly, cam members |39 and 4| move downwardly to expand jaws |33 and |38 radially and outwardly to engage with the inner side wall of the runners and thus hold the cylinder thereon. At the same time cam 58 moves downwardly to move retainer jaws |52 outwardly and over the top of the cylinder to retain the latter on the chuck. The chuck, in turn, is rotated by spindle I9, in a manner to presently appear, to rotate the cylinder 60 therewith.
The outer side walls and the apex of runner |37 of cylinder 6|) are adapted for engagement by a roller |18 having an upper curved wall |19 and a lower curved wall |88, the curvature of the former wall being greater than the curvature of the latter wall, wall |19 engaging with the top side wall of runner |01 and wall |85 engaging with the bottom side wall of the runner. In the same manner the outer side Walls and the apex of a runner |89 of the cylinder are adapted for engagement by a roller |8| having an upper curved wall |82 and a lower curved wall |83, the curvature of the former being less than the curvature of the latter wall, wall |82 engaging with the top side wall of runner |68 and wall |83 engaging with the bottom side wall of the runner.
Roller |18 is mounted by way of a stub shaft |84 within a bracket |85 (see Fig. 5) the bracket being pivotally connected by way of a pin 89 and an arm |81 to one end of a supporting member |83. When adjustment of roller |19 on bracket |95 is required, the lower portion of the bracket may have a bore |89 (Fig. 6) formed therein for the reception of a hollow pin |99 which is yieldably urged by way of a spring I9! into engagement with a wall of supporting member |88. A second and aligned bore is threaded for adjustably receiving therein a threaded stub shaft |92, the latter carrying a pin |93 about which one end of spring I9| is sleeved to abut with an outer face of shaft |92. Rotation of shaft |92 therefore will actuate pin |90 to position bracket |85 relative to member |88 as desired. To dei-lne a limit for outward motion of pin |99 within bore |89, the pin may be provided with an enlarged head |94.
Roller |13 is in engagement with a larger roller at a point diametrically opposite to the point of engagement with runner |91 and in a similar manner, roller 58| is in engagement with a larger roller |95. inasmuch as the mounting and operation of both rollers |95 and |95 is the same, the operation of only one of the rollers will be considered in detail herein.
Roller |95 is mounted for rotation within a bearing housing |91 by way of a stub shaft |98, the housing being fastened to and movable with a block |99 which is slidable on a stationary member 299 secured to supporting member |38, the latter, in turn, having an enlarged ange through which pass bolts 20| for securing the stationary member to member |88. A portion of movable block |99 is provided with a recess 282 with which cooperates the rounded end of one arm of a bellcrank lever 293, the lever being pivotally mounted by way of a transverse pin 284 carried within a recessed portion 205 of stationary member 299. The opposite arm of bellcrank 293 is connected by way of a pivot pin 206 journaled in a yoke 291 which is fastened by way of bolt 289 to a piston rod 209 for up and down movement fby the latter. Piston rod 299 is adapted for operation by a piston (not shown) movable within a cylinder 2||l, the base of the cylinder being pivotally mounted by way of a pin 2| and a block 2|2 on a supporting standard or bracket 2|3 fastened by way of bolts 2 i4 to wall I |2. Cylinder 2|0 is enclosed within a protective housing 2|5 which passes under and to the side of movable block |99 (Fig. 7), the movable block supporting thereon by way of screws 2|6, a protective cover 2 1 so that block |99 may move relative to housing 2 l5 and still maintain the latter closed Iby means of cover 2 I 1. The upper portion of cylinder 2li) supports a clock or timer mechanism 2|8 thereon by way of a bracket 2|9.
When cylinder 6|) is inserted on the chuck |29, draw bar |43 is in an upward position (indicated by broken line 229 of Fig. '1) so that expanding jaws |33 and |38 as well as retainer jaws |52 have been retracted to their inward position. As cylinder Sil has been lowered on the chuck sumciently to rest the bottom thereof on shoulder |53 of ring |54, draw bar |43 is moved downwardly by piston rod |II which is moved upwardly within cylinder |12, the latter being pivotally mounted by pin |15 to compensate for the arcuate path of travel of the end of lever |91 connected to the piston rod. Downward motion of the draw bar causes downward movement of cam member |58 whose surface |52' cooperates with surface |56 of plungers |9| to extend the retainer jaws 52 against the action of spring it over the top end of the cylinder to retain the latter against shoulder |53. ln addition, cam members 35 and Uil move downwardly so that their inclined surfaces lSl and M2 cooperate with inclined surfaces E35 and lllll of pl-ungers i3d and to extend jaws 33 and 38 against the action or" springs lill and 149 into engagement with the inner side walls of runners lill and m8 as shown in 7. Cylinder 60 is thus locked with chuck iil for rotation thereby.
The motor (not shown) for driving pulley l2 and shaft 25 is thereupon energized to operate worm gear 623 and spindle H9. The spindle being connected to chuck i2@ rotates the latter whereupon cylinder Si) is rotated by the chuck through expanding and retainer jaws lt, Hi8 itt. The side walls ll and i oi roller lli being in engagement with the lower and upper side walls of runner lill and side walls i82 and 83 of roller i8! being in engagement with the top and bottom walls o runner IBS, rolling of both rollers I'lB and iti occurs, it being noted that at this point rollers il and I8! are both slightly spaced from the apices of their related runners. As cylinder H2 operates to actuate draw bar ille and the motor is energized to spin the spindle and the cylinder (iii, cylinder 2l@ operates to move piston rod 2l9 upwardly whereupon bellcrank 2% is pivoted to move block ISS and roller i525 therewith to the left to engage roller i'lS and thereby move the latter against cylinder El@ until roller lle engages with the apex of runner lill. Continued inward movement of the roller by the bellcrank compresses the apex of the runner inwardly to flatten the apex of the runner so that as a result of such compression, the inner walls of the runners being supported by jaws 33, the thickness of the runner at the apex thereof will be increased to provide the runner with a greater amount of metal thereat than that present at the side walls of cylinder Eil. As an example, with the above described rolling machine the thickness of the apices of the runners so formed on a cylinder having a wall thickness of .060 inch will increase to between .084 to .090 inch which represents an increase over the original thickness of forty (40) to fty (50) per cent.
in operation, a button (not shown) is depressed to actuate the piston of cylinder H2 so that draw bar M3 is pulled downwardly to actuate cams Ifi, lill and |153 to expand jaws 533, Uit and 52 outwardly. As draw bar 43 moves downwardly it closes an electrical switch which not only energizes the electrical motor for rotating chuck E29 and cylinder 6B therewith but also operates two reversing air valves (not shown) to operate the pistons of cylinder El@ and the corresponding cylinder of roller 96. Air is thus caused to communicate with the lower side of the pistons While oil or other hydraulic fluid communicates with the upper side of the pistons, a bleed being provided for each cylinder so that the fluid escapes at a metered rate whereby both piston rods travel upwardly at a uniform rate to move rollers |18, itil and 18E, teli inwardly at a uniform rate. Electrical clock or timer BIS controls the time of the rolling operation and the lower end of an adjustable bolt 22S defines a limit stop for movement of piston rod 2li@ and a similar timer and limit stop control the piston rod of roller |96. Shortly after the piston rods engage with the limit stops indicating the limit of inward roller motion, mechanism ZIB acts to reverse the air valves whereupon the rollers are retracted from cylinder piston rod lli of cylinder H2 is reversed to move the draw bar upwardly whereby springs lill, les and itil retract jaws 33, it and le?. inwardly and the motor driving the chuck is deenergized. The cylinder is removed from the rolling machine and replaced by another similar cylinder whose runners, formed on the press, are to be rolled and compressed inwardly.
As will be apparent from Fig. 5, rollers and E, while arranged at diametrically opposite points relative to chuck lf to engage runner at opposite sides of the cylinder so arranged that one of the rollers is mounted at one side of the center of the chuck while the other roller is mounted at an opposite side of the center of the chuck. By reason of this latter mounting the rollers are prevented from dislodgment from their desired position by the spinning cylinder with which they engage.
There has thus been provided a novel apparatus for forming ribs or runners on a metal cylinder comprising a press which not only forms the runners on the cylinder but also swages the ends of the cylinder together with a rolling r f chine for compressing the apices ci the r inwardly to provide a thickness oi mate-.. the apices of the runners which is than the thickness oi the metal in the walls of the cylinder.
Although but a single embodiment oi the present invention has been illustrated and described in detail, it will be expressly understood that the invention is not limited therto. Various changes may be made in the design and arrangement of the parts without departing from the spirit and scope of the invention as will now understood by those skilled in the art.

England beat Sri Lanka in second Test | Daily Mail Online
Pietersen and Swann get the job done: Strauss relief as England live up to No 1 tag
Published: 04:24 EST, 7 April 2012 | Updated: 15:47 EST, 7 April 2012
Andrew Strauss jumped to his feet clapping furiously and emitted a yell that could be heard all the way back at Lord’s.
Kevin Pietersen had just hoisted Sri Lanka’s winder-up-in-chief, Tillekeratne Dilshan, for six to confirm England’s win in the second Test in Colombo by eight wickets, ending a run of four successive defeats and securing a 1-1 series draw after their dismal 3-0 drubbing by Pakistan in the UAE.
Just in case anyone has been holidaying on the moon for the past week or so, the reason for Strauss’s uncharacteristic show of emotion was that, in that instant, two things were confirmed: his team’s status as still the No 1 Test team in the world and his own right to continue as their captain for the foreseeable future.
Soon afterwards Strauss, who had earlier missed the chance to round off the winter with the captain’s innings his supporters craved when he fell for a sixth-ball duck, made clear his thoughts on the matter.
‘I had no doubt this was not the time for me to go,’ he said. ‘I’m very determined and committed to see us improve as a side.
‘It’s been an interesting week or two and I think it’s very important we don’t get carried away with whatever the issue of the day is. We’ve done that very well over the past couple of years and obviously I needed to do it and perform in this game — and we needed to do it as a team. I thought we did it well.
‘When you’ve lost four in a row you’re not thinking about being No 1, you’re thinking about winning the next one. I saw a steely determination on everyone’s part to make sure we finished the winter on a high, and it was fantastic to be able to do that.’
Strauss was officially confirmed as skipper for this summer at the head of the 25-man England performance squad. If evidence were needed of how much he means to this team and how relieved all involved will be that, for the time being, his future is no longer on the agenda, it was fitting it should be presented in spectacular style by the man he replaced as captain.
Pietersen is back to his breathtaking best with the bat, his second six taking him to 42 in an unbroken third-wicket stand of 66 with Alastair Cook (49 not out) to add to his brilliant first-innings 151 and earn the man-of-the-match award.
He carried on all guns blazing long after the 94 runs required for victory had been made. Pietersen responded to the questions that had been irking the England skipper all week regarding his leadership and his place in the side, first by insisting that Strauss remains the best man for the job, then by claiming he still will be when Australia arrive for the Ashes rematch in 2013.
Rounding on one interviewer, his voice rising to compete with the Barmy Army’s celebrations surrounding him, Pietersen said: ‘We are backing him to the hilt because I’d like you guys to tell me who’d replace him. I’d like you to give me one name or two names of who’s going to replace Andrew Strauss.’
While the noise and excitement apparently caused him to forget the claims of batting partner and vice-captain Cook, Pietersen added: ‘Nobody can replace Andrew Strauss because unfortunately there is no one out there at the moment who is going to do the job that Strauss will do against West Indies or South Africa or Australia next year. He’s a great captain and you boys need to get off his back.’
Pietersen’s pyrotechnics aside, that any legitimate concerns over Strauss’s batting and captaincy had been erased was down to their consistently irrepressible attack, and Graeme Swann in particular. With his second-innings 6-106, and 10 in a match for the second time, Swann overtook Jimmy Anderson in their personal battle to take the most Test five-fors (currently 13-12).
The big one: Graeme Swann of England celebrates taking the wicket of Mahela Jayawarene
His critical contribution yesterday came when he ended Mahela Jayawardene’s 16 hours and 22 minutes of batting in the series at 238-7, having him caught by Cook at short leg for another excellent 64.
Sri Lanka added a further 40 to end on 278 — 93 ahead. Cue Dilshan, among others, helpfully pointing out that England had folded for 72 when chasing 145 in the second Test against Pakistan in Abu Dhabi.
Strauss conceded the low point of the tour had been in their minds yesterday, but despite his untimely duck, with Cook and Pietersen in this mood, success was achieved with almost arrogant ease.
‘They’re horrible chases, because everyone expects you to win,’ said Strauss. ‘It’s almost like trying to sink a three-foot putt. You know it should go in but it doesn’t always.
‘We were determined to make sure we didn’t make the same mistakes as we did in Abu Dhabi, determined to be a bit more proactive about things and Cooky and KP did that exceptionally well.’
As for lessons learned, both Swann and Anderson declined to highlight that England’s belated success may have had something to do with the fact that while they have been performing heroically all winter, only here were they adequately supported by the batsmen.
And no one needs reminding that after succumbing to spin in the shape of Saeed Ajmal and Rangana Herath, and with four Tests against India in the subcontinent to follow the summer action against West Indies and South Africa this year, the exact same challenge lies in wait come November.
True to form, however, Pietersen managed the last word on those thorny issues as well.
‘Our bowlers are world class, the best in the world, and the batters need to match them … and we did in this game,’ he said. ‘Having two months off before playing Pakistan, I reckon we were probably undercooked. We decided as a group of batters to try to turn up here, and this is the reward for putting in a lot of hard work.
‘Positivity is essential when you are playing against spinners. You’ve got to try to get the bowler to bowl where you want him to, not where he wants to. We’ve definitely made a lot of progress and we’ll go OK in India at the end of the year.’
James Anderson: Even the Sri Lankans admit nobody spins it... Pietersen hails England performance as tourists draw series... LIVE: Sri Lanka v England - all the action on day five of... The great DRS debate... For or against? Our experts offer...

7. A labeling machine according to claim 4, wherein separator means for separating the support strip and a label is disposed between the active print means and the gripper means, the separator means being associated with means for rewinding the support strip.
8. A labeling machine according to claim 1, wherein the gripper means comprise a suction member holding the label via a non-adhesive face thereof.
9. A labeling machine according to claim 1, wherein the placing means comprise a pusher movable in a direction parallel to the pivot axis of the labeling head and pushing the label via its non-adhesive face towards the article to be labeled.
10. A labeling machine according to claim 1, wherein the structure includes a bracket forming a support for the labeling head, the labeling head being movable on the bracket in a direction perpendicular to its pivot axis and perpendicular to a forward travel direction of the article to be labeled.
The invention relates to a labeling machine.
As a general rule, a conventional labeling machine comprises a conveyor for transporting articles to be labeled and a labeling head mounted on a bracket extending over the conveyor and fitted with label-gripper means that hold the label in a plane parallel to the face of an article in register with the labeling head. Applicator means secured to the labeling head are adapted to move the label held by the gripper means onto the article that is to be labeled. The labeling head moves on the bracket in a direction perpendicular to the travel direction of the conveyor.
In order to adjust the position of the label on the article, the movement of the labeling machine head on the bracket is controlled as is the advance of the conveyor in such a manner as to cause a reference point on the labeling machine head to coincide with a reference point on the article, in general the corner of a label-receiving zone on the article.
The labeling machine is sometimes required to be capable of positioning the label on the article in any specified orientation. In order to be able to do this, the labeling head of such a labeling machine can turn about a pivot axis.
However, if no special precautions are taken, then turning of the labeling head gives rise not only to a change in the orientation of the label relative to the article, but also to an offset in the position of the label relative to the position expected for it on the article. This offset is either the result of the reference point of the labeling head not coinciding with the pivot axis of the labeling head, or else the result of the label being offset relative to the pivot axis.
In order to remedy that offset, it is appropriate to correct the position of the article relative to the labeling head in the travel direction of the conveyor by moving the conveyor forwards or backwards, and in a direction that is perpendicular thereto by moving the labeling head on the bracket so as to reposition the pivoted label relative to the article. These correcting displacements make it awkward to position a label relative to an article. Furthermore, these displacements vary with varying angle of rotation for the labeling head, further complicating control of pivoting of the labeling head.
According to the invention, the gripper means is arranged on the labeling head in such a manner that when it holds a label, a corner of the label coincides substantially with the point of intersection of the pivot axis with the plane of the label.
Thus, in order to position the label correctly on an article, the conveyor is caused to advance and the labeling head is moved so that the pivot axis intersects both the corner of the label and the reference point on the article. The label then pivots with the labeling head so that its corner continues to coincide with the reference point on the article, regardless of the angle through which the labeling head is pivoted. There is no longer any offset induced by the pivoting of the labeling head.
Advantageously, the labeling head has a printer with active print means and with means for driving the label through the printer, the gripper means being situated immediately downstream from the active print means.
Placing the active print means on board the labeling head, avoids incessant go-and-return trips of the labeling head between external print means and a labeling position overlying the conveyor of the labeling machine.
Advantageously, the active print means are controlled by control means that are not secured to the labeling head. The portions of the printer that are not active from the point of view of printing are thus located on the labeling machine, thereby simplifying the design of the labeling head.
Preferably, the active print means are adapted to receive a strip supporting adhesive labels coming from a roll, the labeling head having deflector members for imparting a twisted trajectory to the strip between the roll and the active print means.
By �twisted�, it should be understood that the midplane of the strip does not remain constant as the strip travels between the roll and the active print means. The roll is thus offset from the active print means, thus making it possible to design a labeling head that presents a smaller moment of inertia, and that is of more compact structure.
In a first embodiment, the roll is placed on the labeling head beside the active print means. The roll is thus placed close to the axis of rotation of the labeling head, thereby reducing its moment of inertia.
In a second embodiment, the roll is mounted to rotate on the structure of the labeling machine, with the deflector members comprising a deflector cylinder secured to the labeling head and extending parallel to the pivot axis of the labeling head. In this way, the labeling head is lightened by a weight corresponding to the weight of the roll, and because of the deflection parallel to its pivot axis, the labeling head can still be oriented at any angle while nevertheless ensuring that the support strip is fed properly.
Advantageously, separation means for separating the support strip from the label are located between the active print means and the gripper means, such separation means being associated with means for re-winding the support strip.
Preferably, the gripper means comprise a suction member holding the label via a non-adhesive face thereof.
The gripper means is then associated with placing means comprising a pusher movable in a direction parallel to the pivot axis of the labeling head and pushing the label by means of its non-adhesive face towards the article that is to be labeled.
In order to position the label relative to the article that is to be labeled, the structure includes a bracket forming a support for the labeling head, the labeling head being movable along the bracket in a direction perpendicular to its pivot axis and perpendicular to a travel direction of the article to be labeled.
Other characteristics and advantages of the invention appear more clearly in the light of the following description of particular, non-limiting embodiments of the invention. Reference is made to the accompanying figures, in which:
FIG. 1 is a perspective view of a labeling machine of the invention;
FIG. 2 is a side view in partial section showing a labeling head fitted to a labeling machine of the invention;
FIG. 3a is a diagrammatic plan view showing a portion of a prior art labeling machine;
FIG. 3b is a diagrammatic plan view showing a portion of a labeling machine of the invention;
FIG. 4 is a fragmentary perspective view of a labeling head fitted to a labeling machine of the invention; and
FIG. 5 is a fragmentary perspective view of a labeling head fitted to a labeling machine of the invention.
With reference to FIG. 1, a labeling machine comprises a structure 1 carrying a conveyor 2, in this case of the roller type, together with a labeling head 3 which is described below with reference to FIG. 2.
The labeling head 3 is mounted to move on a bracket or gantry 24 of the structure 1 which extends over the conveyor 2 transversely to a forward travel direction X thereof. The head is movable along the bracket 24 in a direction Y that is substantially perpendicular to the forward travel direction X of the conveyor 2. The labeling head 3 is also suitable for pivoting relative to the bracket 24 about an axis of rotation Z that is perpendicular to the direction X and Y.
Displacements along the directions X and Y enable the labeling head 3 to be put into a determined position over an article to be labeled 6, while pivoting about the axis Z enables the orientation of the labeling head 3 to be adjusted relative to the article 6.
The structure 1 also carries a unit 4 containing the control electronics for the labeling machine, together with a console 5 enabling an operator to control the labeling machine.
With reference to FIG. 2, the labeling head 3 comprises a support 20 mounted to rotate about the axis Z on a pivot 21 that is movable along the bracket 24. The support 20 carries a printer 7 for printing adhesive labels carried by a support strip 8 engaged in the printer 7, and advancing in the direction represented by arrows. In conventional manner, the printer 7 has a drive roller or �capstan� 9 and a thermal print head 10 pivotally mounted about an axis parallel to the capstan axis and urged against the capstan by resilient means 11. The support strip 8 passes between the capstan 9 and the thermal print head 10 so as to enable labels carried by the support strip 8 to be printed. The capstan also drives the support strip 8 and thus causes the labels to move past the print head 10.
In this case, the printer 7 on board the labeling head comprises only the active print means of a printer, while the means for controlling said active print means are located elsewhere in the unit 4 so as to lighten the labeling head 3 and so as to put all of the electronics of the labeling machine in a single location.
Downstream from the capstan 9, the support strip 8 passes via a separator 12, constituted in this way by a small-diameter roller causing the support strip 8 to pass round a tight curve so that the labels separate from the support strip 8. There can thus be seen a label 30 separated from the support strip 8. The support strip 8 is deflected by a set of rollers towards a take-up spool 13. In a variant, the spool 13 could be used for driving the strip and causing the labels to travel past the print head 10.
The label 30 continues to advance and it is taken up by gripper means 14 located immediately downstream from the outlet from the printer 7, overlying the label 30.
In this case, the gripper means 14 comprise a suction device having a bearing outline 16 lying in a plane that is substantially normal to the pivot axis Z of the labeling head 3. When the label 30 is in register with the bearing outline 16, suction is established between the bearing outline 16 and the label 30, thus enabling the label to be held against the bearing outline 16. The suction is established by suction means, represented merely by a single suction hose.
Thereafter, to take the label 30 and press it against the article 6, a pusher 17 having a sliding axis parallel to the pivot axis of the labeling head 3 is disposed on the labeling head so as to push the label 30 up to the article 6, the label 30 remaining pressed against the pusher 17 by the effect of aerodynamic drag acting on the label 30. The pusher 17 is connected to a piston-forming rod 18 that slides in an actuator 25. The pusher 17 is actuated in this case by admitting compressed air into the compartment 24 for pushing against the piston of the rod 18. The compressed air transmits the necessary impulse to the rod 18 to ensure that the pusher 17 reaches the article 6 for labeling. The label 30 is then stuck on the article 6 and the pusher moves back up under drive from a return spring 19.
According to the invention, the label 30 is held by the gripper means 14 so that a corner of the label 30 coincides with the intersection of the pivot axis Z of the labeling head 3 and the plane of the label 30.
FIGS. 3a and 3 b show the advantage of this disposition.
FIG. 3a relates to a labeling machine that does not have this disposition, and an article 6 present on the conveyor 2 of the machine, which article is to receive a label 30 in the position 40 shown in dashed lines.
To do this, the position of a reference point 41 on the article 6 is known. The conveyor 2 and the labeling machine 3 (not shown but the intersection of its axis Z is marked in the figure) are operated in such a manner that the corner of the label 30 carried by the labeling head 3 coincides with the reference point 41 on the article 6. Then to give the label 30 the required orientation, the labeling head 3 is turned through 90�.
It can then be seen that the label 30 now occupies a position 42 that is offset by a distance d1 in the forward advance direction X of the conveyor 2 and by a distance d2 in the travel direction Y of the labeling head 3. It is then necessary to operate the conveyor 2 and the labeling head 3 so as to move the label from position 42 to position 40.
The offsets d1 and d2 are shown for turning through 90�, but similar offsets exist likewise for turning through any angle. The particular values of the offset depend on the pivot angle, which makes controlling the labeling machine complicated.
FIG. 3b shows a labeling machine of the invention in which the corner of the label 30 coincides with the pivot axis Z of the labeling head 3. If the axis Z of the labeling head is in alignment with the reference point 41 on the article 6, then turning the labeling head does not cause the corner of the label to move, so the corner continues to coincide with the reference point 41 on the article 6 regardless of the angle through which the labeling head 3 is pivoted.
In the example shown, turning the labeling head through 90� places the label 30 as held by the gripper means 14 so as to overlie the expected position 40 for the label on the article 6. This makes controlling the labeling machine much simpler.
Returning to FIG. 2, it can be seen that the support strip 8 and the label 30 held by the gripper means 14 follow a plane trajectory through the printer 7 and downstream therefrom. The term �plane� is used herein to mean that the middle plane of the support strip 8 remains the same all along the trajectory, thus defining a plane in which the trajectory of a midpoint on the support strip 8 is marked.
In traditional printers, the support strip 8 comes from a feed roll whose midplane coincides with the plane of the trajectory followed by the support strip 8 through the printer 7. Given the presence of the bracket 24 and of the pivot 21 above the labeling head 3, that method would require the roll to be placed in line with the printer 7, i.e. to the left in FIG. 2. The roll 15 would then be offset considerably from the axis Z and would therefore make the labeling head bulky, giving it a moment of inertia poorly suited to turning the printing head.
In order to avoid that drawback, the support strip 8 is caused, in the invention, to follow a twisted path between the roll and the printer so as to place the roll in a position where it reduces the moment of inertia of the labeling head. The term �twisted� is used to mean that the midplane of the support strip 8 does not lie continuously in the same plane between the feed roll 15 and the printer 7.
FIGS. 4 and 5 show two possible locations for the roll 15 in order to obtain this reduced moment of inertia. In these figures, only the labeling head 3 and the feed roll 15 are shown.
In FIG. 4, the feed roll 15 is installed on board the labeling head 3, but it is located beside the printer 7 on the opposite side of the support 20 from the printer 7 so that the midplane of the roll 15 and the midplane of the support strip 8 in the printer 7 are parallel and do not coincide. The support strip 8 is deflected towards the printer 7 by means of successive deflector cylinders 22.1, 22.2, 22.3, and 22.4, with the first and last deflector cylinders 22.1 and 22.4 being placed on a common axis parallel to the axis of the roll 15 and to the axis of the capstan 9 in the printer 7 (not visible in this figure). The arrows show the direction in which the support strip 8 advances.
In FIG. 5, the roll 15 is placed on the structure 1 of the labeling machine so that its axis of rotation is parallel to the pivot axis Z of the labeling head.
The support strip 8 passes firstly over a deflector cylinder 23.1 parallel to the pivot axis Z of the labeling head 3 and carried thereby. Thereafter, the support strip 8 is directed towards the printer 7 by means of a deflector cylinder 23.2 that is inclined at 45�, after which it is guided by a deflector cylinder 23.3 parallel to the axis of rotation of the capstan 9 (not visible in this figure). The first deflector cylinder 23.1 enables the labeling head 3 to pivot while ensuring that the path followed by the support strip 8 is compatible with such pivoting. The roll 15 can be fitted with tensioning means so as to ensure that the strip 8 takes up any excess length in the event of the labeling head 3 being moved in the direction Y towards the roll 15.
