     DETAILED DESCRIPTION OF THE INVENTION 
     Referring now to the drawings and in particular to FIG. 1, the bow sight, 1, is shown in elevation to comprise primarily of the support structure, 2, and the sight assembly, 3. The support structure, 2, comprises bracket, 4, which is secured to bow, 5, by means of fasteners, 6, and elongated member, 7, which is mounted on bracket, 4, by fasteners, 8. Elongated member, 7, is provided with mounting bracket, 9, to which is attached, sight assembly, 3, by means of fasteners, 10. 
     Sight assembly, 3, includes housing, 11, lead screw means, 12, and sighting block, 13. Housing, 11, is provided with flanges, 14, and, 15, at the upper and lower ends respectively. Lead screw housing, 22, is mounted between brackets, 14, and, 15, and lead screw, 12, is disposed within housing, 22, and its rotation is controlled by knurled knob, 16, which is secured to the upper end of lead screw, 12. Lead screw, 12, passes through sighting block, 13, and engages threads therein in such a manner that rotation of lead screw, 12, in one direction causes block, 13, to rise and rotation in the opposite direction causes block, 13, to descend. The vertical position of block, 13, may be secured or clamped by locking means, 17, which is controlled by knurled knob, 18. Locking means, 17, is shown in greater detail in FIG. 2. 
     FIG. 2, describes in greater detail the vertical control of sighting rod, 19. As shown in FIG. 2, plunger, 23, is connected to knob, 18, by screwing its threaded end, 27, into knob, 18, while the other end of plunger, 23, is provided with threaded rack, 26, which engages lead screw, 12. Spring, 25, is disposed about plunger, 23, and between stop block, 24, mounted in a passage in the block, 13, and the shoulder of rack, 26. When coarse vertical adjustment is desired, knob, 18, is pulled out thus disengaging rack, 26, from lead screw, 12. Fine adjustment of the vertical position of block, 13, is obtained by rotating lead screw, 12, by rotating knob, 16, which engages rack, 26, which is restrained from rotating. 
     The transverse position of sighting rod, 19, with sight marker, 20, on an end thereof, is controlled by assembly, 21. Assembly, 21, is shown in greater detail in FIG. 3. 
     As shown in FIG. 3, the sighting rod, 19, passes through a passage in a bushing, 29, and is locked in position therein by lockscrew, 30. The threads on sighting rod, 19, engage knob, 36, which is the control for transverse travel of rod, 19. Housing, 31, is provided with tab, 32, which engages the groove, 33, in bushing, 29, and prevents the bushing from turning when knob, 36, is rotated. Housing, 31, is also provided with a chamber in which spring, 34, is disposed and surrounds rod, 19, and a knob, 35, shown in this embodiment as integral with a housing, 31, mounted in block, 13. The knob, 35, is used as a finger grip in mounting the housing, 31, in the block. The spring 34 is caged and compressed between the bushing, 29, and an internal annular shoulder in the housing 31. Fine transverse adjustment of rod, 19, is obtained by simply rotating knob, 36. For coarse adjustment, marker, 20, is pushed slightly by hand towards block, 13, thus reducing the binding of knob, 35, on knob, 36, caused by spring, 34, pushing bushing, 29, towards marker, 20. Then knob, 36, is easily rotated away from or towards block, 13, and then the pressure on marker, 20, is removed. 
     FIG. 4 and FIG. 5 show an alternate configuration for the vertical adjustment. Block, 13, is modified slightly and becomes block, 37. In this configuration housing, 22, is eliminated and lead screw, 12, passes through hole, 44, in block, 37, and through a hole, 45, in a rack block part of a push rod, 38. Hole, 45, in rod, 38, is irregular in that a portion thereof, 39, is threaded while the other portion, 40, has the threads removed, or equivalent. Without pressure on rod, 38, spring, 41, engaging shoulder, 42, in rod, 38, forces engagement of the threaded portion, 39, with lead screw and rotation of screw, 12, causes block, 37, to move vertically, thus the fine adjustment. For coarse adjustment, rod, 38, is pushed on its end, 43, causing threaded portion, 39, to disengage from screw, 12, and allowing easy movement of block, 37. The configuration shown in FIG. 4 and FIG. 5 may be further complemented by attaching shoe, 46, to the base of spring, 41, to facilitate the sliding contact with housing, 11. 
     FIG. 6 shows essentially the inverse to that shown in FIG. 4 and FIG. 5. Block, 37, becomes block, 47, again the block, 47, is provided with hole, 51, which is threaded on one side, 53, and smooth on the other side, 52. Spring, 51, keeps rack, 50, engaged with lead screw, 12, except when coarse adjustment is desired in which case knob, 49, is pulled out disengaging rack, 50, which is attached to knob, 49, by shaft, 48. 
     A further modification to block, 13, may improve performance is shown in FIG. 7 and FIG. 8. Block, 13, is provided with circular recess, 54, into which synthetic sponge, 55, is disposed and secured to block, 13, by adhesive, 56. Paper, 57, is provided and secured to sponge, 55, to provide smooth and uniform contact with housing, 11. 
     Another feature which is optional is shown in FIG. 1 and FIG. 3. In this arrangement, housing, 31, is provided with peripheral slot, 59. Threaded hole, 60, is then provided in block, 13, into which set screw, 58, enters, locking housing, 31, in place. This is a significant feature. It is contemplated that housing, 31, may be reversed by simply unscrewing from block, 13, and inserting from the other side thus allowing quick change from right to left handed shooters. To prevent movement of housing, 31, in this configuration, set screw, 58, is used. It is also contemplated that this device may be made so that housing, 31, is integral with block, 13, thus restricting it to right or left handed shooters depending on which side the rod, 19, is inserted. 
     Another embodiment contemplated herein is that shown in FIG. 9, which is another alternate to vary the means of vertical adjustment. In place of block, 13, block, 61, is substituted. Lead screw, 12, passes through hole, 62, in block, 61, which is partially threaded, 64, and partially clear, 63. To engage block, 61, with lead screw, 12, one simply tightens knob, 65, on screw, 66, in threaded hole, 67, in block, 61, which when knob, 65, contacts housing, 11, draws block, 61, into engagement with screw, 12. For coarse adjustment, one simply loosens knob, 65, and block, 61, disengages from lead screw, 12. 
     Another feature shown in FIG. 1, is the daily condition point marker, 69, Marker, 69, is adjustably mounted in groove, 74, in block, 13, by means of knob, 72, on threaded shaft, 71, in threaded hole, 70, in block, 13. Indicator, 73, on marker, 69, provides reference means relating the position of block, 13, and thus marker, 20, with respect to housing, 11. By setting indicator, 73, on specific points on yardage marker, 68, the range of the bow for pre-determined conditions is established. Yardage marker, 68, which in its preferred embodiment comprises paper, 78, mounted on base, 75, is disposed in channel, 76, in housing, 11, and secured therein by set screw, 77. A particular feature associated with the changeable yardage marker, 68, is that device, 1, may be mounted on a bow on a given day and if a yardage marker is marked for various limbs the bow is then ready for immediate use as the limbs are changed by changing the yardage marker. 
     While I have illustrated and described the preferred embodiments of my invention, it is to be understood that changes and modifications in the form, construction, arrangement and combination of the parts and steps of the Bow Sight and methods of making and using the same may be substituted for those herein shown and described without departing from the nature and principle of my invention.
A bow sight for use with archery bows comprising mounting means adapted to mount the sight on the bow, a sighting member operably mounted on said mounting means and adjusting means mounted on said mounting means so as to control the transverse and vertical movement of the sighting member.
