Graham Irwin leads Irwin Seating Company into the fourth generation
Grand Rapids, Mich., June 29, 2015 - Irwin Seating Company today announced that Graham Irwin has been named the President and CEO of the 107 year-old, family-owned business. Current CEO Earle S. (Win) Irwin will remain active with the company as Chairman of the Irwin Seating Company Board of Directors. The transition has been planned for several years and will be effective July 1, 2015.
Graham Irwin is the fourth generation of the Irwin family to lead the company. Current CEO Earle S. (Win) Irwin took over leadership of the company in 1984 from his father, William Irwin, who had led the company since the end of World War II. The first Irwin to lead the company was Earle S. Irwin, one of three Irwin brothers who helped found the company more than 100 years ago. Three of Win & Kyle Irwin's five sons currently work for Irwin Seating Company. Graham, Colin (Coke) Irwin as the company's Director of Sales and Andrew Irwin as the company's Continuous Improvement Manager.
In his new role, Graham Irwin will assume the day-to-day responsibilities of leading the company while also working with the Board of Directors and Executive Team to explore new opportunities for continued growth. Irwin Seating Company is headquartered in Grand Rapids, Michigan, where it manufactures public seating for movie theatres, auditoriums, arenas, schools, and stadiums. In Altamont, Illinois, the Company manufactures telescopic bleachers and platforms for schools, arenas, convention centers and multi-purpose facilities.
"After more than 30 years as President, CEO and Chairman of the Board of Irwin Seating Company, it is time to begin transitioning leadership to the next generation," said Win Irwin. "For a number of years, we have been working to ensure a smooth transition. Graham has the experience, energy and necessary skills to lead this company to continued success."
Graham Irwin has served in a variety of roles with Irwin Seating Company, beginning as an upholstery line worker in the summer of 1995. After earning an engineering degree from Vanderbilt University in 1998, Graham began his career working as a mechanical design engineer for EnviroDesign, Inc. Then as a manufacturing engineer and production manager with Spectra Logic Corporation before returning to Irwin Seating in 2006 as a product development engineer. Since then, his leadership responsibilities have steadily increased as he worked his way into his current role as Senior Vice President of Product and Business Development and a member of the Board of Directors.
"I've been fortunate to experience a diverse career that began on the manufacturing front lines and spanned a wide range of roles and responsibilities," said Graham Irwin. "I believe that this background, and the resulting familiarity that it provides with virtually every aspect of the manufacturing process and our customers, has prepared me to be an effective leader. I appreciate the trust of my family, the Board of Directors, the Executive Team and the Irwin employees. I look forward to working together with them towards a bright future for our company."
In addition to Graham's mechanical engineering degree from Vanderbilt University he has an MBA from the Daniels College of Business at the University of Denver. He is also member of the Family Business Alliance - an organization committed to helping West Michigan family businesses succeed from generation to generation.

Anyone that travels by air will tell you that the restaurant and services can vary drastically from airport to airport. Some airports have a really good selection and others don't. Some have the restaurant you want, but it's way the heck on the other side of the terminal. Also if you're looking for other things like whether or not the airport has Wi-Fi or where is the closest ATM machine, an app that has all of this info in one spot would be very handy.
GateGuru has all of this and more
One of the biggest problems is not knowing what's on the other side of security. Often times directory apps such as Yelp or AroundMe stop at the TSA line. There's no way of knowing what's near YOUR gate. With GateGuru you can either use the built-in Location services support to show you your current airport or simply key in the airport code/city to find the airport you're headed to. This will help you plan accordingly for an airport that you're on your way to especially if you've never been there before.

May 20, 2015
Simply put, "Cabaret" is one of the best productions I've ever seen at Village Theatre.
However, your enjoyment of the musical will directly correlate with your ability to handle an uncomfortable truth.
Brian Yorkey returns to direct 'Cabaret'
May 12, 2015
He's won a Tony award, not to mention a Pulitzer Prize.
Still, virtually every year he makes a return to where it literally all started for him, Village Theatre.
"Not to get mushy, but this is home," Brian Yorkey said, explaining why he keeps coming back to Issaquah despite a full plate of movie scripts, other plays and projects of various kinds.

1. Field of the Invention
The invention in general relates to vibration analysis, and more particularly, to an arrangement for measuring any vibration in rotating turbine blades.
2. Description of the Prior Art
In the design and operation of a turbine, care must be taken to ensure that no turbine blades are set into vibration during rotation of the one or more blade rows commonly employed. Vibration of a blade sets up fluctuating stresses which can damage or severely reduce the life of the blade.
Various methods exist in order to measure these fluctuating stresses while the turbine is in operation. In one arrangement a plurality of strain gauges are bonded to the turbine blades and the signals from the gauges are transmitted to data acquisition and recording equipment by means of telemetry techniques. This arrangement poses some problems with respect to the life of the strain gauges, the number of strain gauges that may be employed and the economic consideration with respect to the telemetry channels.
A non-contacting method has been proposed for determining turbine blade vibration by using a millimeter wave radar system to direct a narrow beam of electromagnetic energy toward the rotating blade row and analyzing the reflected signal from the blades to detect any abnormal vibration. The present invention utilizes this latter concept in a practical system which determines if any blade is abnormally vibrating, and further identifies which blade or blades are at fault, so that corrective measures may be taken.
The turbine blade detection system includes a plurality of radar sensors operable to transmit a relatively narrow beam radar signal toward the rotating turbine blades of one or more blade rows. The reflected radar signals from the blades are utilized to derive respective output signals indicative of relative blade movement toward and/or away from the respective radar sensors. In order to determine which of the blades may be vibrating, means are coupled to the turbine to provide an output reference signal for each complete rotation, or partial rotation, of the turbine shaft. Circuitry responsive to the reference signal provides respective running counts indicative of the number of turbine blades which have traversed a reference position to thereby specifically identify the particular blades. Gating means are provided for selectively gating the radar output signal and gating means are provided for selectively gating the running counts. A signal processing means is operable to provide enabling signals at predetermined times to the gating means so as to receive the signals therefrom. The signal processing means is additionally operable to analyze the gated radar output signals to provide an indication if the analyzed signal exceeds predetermined limits. In one embodiment the analyzed signal from each respective blade is averaged over a predetermined number of rotations of the turbine shaft.
FIG. 1 illustrates a single radar sensor of the prior art for measuring blade vibration;
FIG. 2 is a view of a turbine system, with portions broken away, illustrating the placement of radar sensors in accordance with the present invention;
FIGS. 3A and 3B illustrate a plurality of radar sensors in relation to a turbine blade row in accordance with the present invention;
FIG. 4 illustrates a typical mounting of a radar sensor;
FIG. 5 is a block diagram illustrating circuitry for obtaining the identification of the rotating turbine blades, in accordance with the present invention;
FIG. 6 is a block diagram illustrating the control of signal flow, in accordance with the present invention; and
FIG. 7 is a waveform of amplitude versus frequency of a radar sensor signal.
A suggestion has been made in the prior to use a millimeter wave radar to detect vibrating blades in a gas turbine. As illustrated in FIG. 1, the radar sensor is operable to project an extremely narrow beam radar signal 12 toward the rotating turbine blades 14. The reflected signal 16 therefrom is detected and processed by radar sensor 10 which then derives an output radar signal, designated FD, indicative of relative blade movement toward and/or away from the radar sensor.
In the present invention, as illustrated in FIG. 2, a plurality of such radar sensors are utilized for determining blade vibration in one or more rotating blade rows. The radar sensors S may be of the millimeter wave type mentioned in FIG. 1 or may be of a higher frequency type such as an optical radar utilizing a coherent light signal as obtained from a laser.
The sensors S are illustrated by way of example as being mounted on the casing of a low pressure steam turbine 18 included as part of a turbine system 20 operable to rotate a generator 22 for the production of electrical energy.
Two sensors can be seen mounted on the outer casing 24 for directing their radar signals toward the last blade row 26 on the generator end as well as two sensors for directing their signal toward the last blade row 26' on the throttle or governor end. By way of further example, two more sensors can be seen mounted on the outer casing 24 for directing their respective radar signals toward respective blade rows 28 and 28'.
Various orientations of the sensors relative to the blade rows are possible and FIGS. 3A and 3B illustrate two such orientations. In FIG. 3A, two radar sensors 34 and 35 are utilized for obtaining blade vibration data of the same last blade row 26. Radar sensors 34 and 35 are oriented so that their narrow beams are directed toward the blade tips substantially in the general plane of the blade row.
FIG. 3B illustrates a radar sensor 36 oriented so that its narrow beam is at an angle θ with respect to the general plane of the blade row. In turbine systems wherein groups of blades are connected at their tips by means of a shroud, an angular orientation of the radar beams relative to the plane of the blade rows would be utilized.
A typical mounting of a radar sensor such as 36 is further illustrated in FIG. 4. The electronics portion 40 of the radar sensor 36 is mounted on a bracket 42 secured, such as by welding, to the outer casing 24.
A waveguide 44, for the conveyance of electromagnetic energy extends from the electronics portion 40 down to a position adjacent the blade row 26 and in so doing passes through an aperture in the outer casing 24 with the aperture maintaining pressure integrity by means of a sealing arrangement 48.
Within the turbine, waveguide 44 is enclosed within a waveguide support 50 which in turn is connected to an adjustable support 52 connected to an internal structure of the turbine such as defuser 54, a portion of which is illustrated. The arrangement of FIG. 4 is described in more detail and claimed in copending application Ser. No. 403,432 filed July 30, 1982, and assigned to the same assignee as the present invention.
Having a plurality of radar sensors, means must be additionally provided for determining which of the plurality of blades, if any, are vibrating. Accordingly, means are provided for obtaining a running count of the number of blades which pass a reference position, for each blade row which has a radar sensor or sensors associated with it. Thus, in FIG. 5 means are coupled to the turbine system so as to provide an output reference signal for each 360� of rotation of the blade rows about the turbine's central axis and relative to a reference position. In order to provide this output reference signal a detector 60 is positioned adjacent balance ring 62 connected to the rotor disc 64. Balance ring 62 includes a notch 66 therein which when passing relative to detector 60 will cause an output reference signal therefrom to be supplied on line 68.
A running count of the turbine blades during their rotation is provided by means of one or more blade counting circuits, of which two, 70 and 71 are illustrated. Each blade row that has one or more associated radar sensors will have an assigned blade counting circuit. In a double flow design such as illustrated in FIG. 2, each blade counting circuit may be operable to count not only the blades in one blade row but those in its symmetrical counterpart as well.
In one embodiment, a blade counting circuit such as 70 will include a frequency multiplier 72 of the type which will provide a certain number of output pulses between successive input pulses. For example, if a blade row has X number of blades then frequency multiplier 72 will provide X output pulses on line 74 from one reference pulse to a subsequent pulse supplied on line 68.
The blade counting circuit 70 additionally includes a counter 76 which is operable to count the pulses on line 74 and to provide an indication thereof on line 78, which in a preferred embodiment will be comprised of a plurality of individual leads providing a binary output representation of the particular count. The count will be initiated in response to the reference signal being supplied, via line 80, to the reset R of the counter 76.
It is seen therefore that each time a reference signal is provided by detector 60, a running count will be provided on output line 78 from the blade counting circuit 70 indicative of which of the X number of blades is passing the predetermined reference position. For some designs, it may be desirable to provide more than one radar sensor for a particular blade row. In such instance the first radar sensor output signal may be associated with blade number one whereas a second sensor output would be associated with a different numbered blade. In order to provide an output running count of this different numbered blade, as well as any other blade associated with further radar sensors for that blade row, the blade counting circuit includes offset means in the form of summers 82 and 84 both of which receive the running count appearing on line 78 and modify it by an offset amount supplied on respective lines 86 and 88. When this offset amount is added to the running count appearing on line 78, the offset running count associated with the other radar sensors will appear on respective lines 90 and 92. It is to be understood that an offset circuit may be provided for each radar sensor.
Blade counting circuit 71 will be similar to circuit 70 but will include a frequency multiplier 94 for supplying Y pulses between successive reference signals where Y would be equivalent to the number of blades in a blade row under observation by radar sensors. One or more output lines such as lines 97 and 98 would provide a running blade count for each radar sensor associated with that particular blade row.
If more blade rows with different numbers of blades are to be observed, additional blade counting circuits would be provided. In addition, although FIG. 5 illustrates a reference signal being provided for every 360� of rotation, one or more notches may be provided in the balance ring 62 to provide the reference signals at less than 360� rotations. In such instance, the frequency multiplier output would be proportionally reduced and a divide circuit would be provided in line 80 so that counter 76 would be reset at the appropriate time.
Means are provided for examining a radar signal pertinent to a particular blade for detecting any abnormal vibrations so that corrective measures may be taken. By way of example, and with reference to FIG. 6, let it be assumed that two different blade rows each having a different number of blades, are being examined with two radar sensors per blade row. Thus, the blade counting circuit 70 of FIG. 5 may be utilized to provided running blade counts on two output lines 78 and 79 with the count on line 78 being indicative of the blade being examined by radar sensor 100 and with the count on line 79 being indicative of the blade being examined by radar sensor 101. The blade counting circuit 71 for the other blade row will include two output lines 97 and 98 with the count on line 97 being indicative of the blade being examined by radar sensor 102 and the count on line 98 being indicative of the blade being examined by radar sensor 103.
Gating means are provided for gating the blade count as well as the radar signal and accordingly, gates 110 to 113 govern the gating of the blade counts while gates 114 to 117 govern the gating of the radar signals.
Signal processing means such as computer 120 is operable to provide enabling signals to the first gating circuits 110 through 113 as well as to the second gating circuits 114 through 117 so as to selectively gate the radar signal and its associated blade identification for analysis by the computer 120. The gated blade counts are in a binary form for use by the computer whereas the radar signals are in an analog form. Accordingly, an analog to digital converter circuit 122 is provided for converting these signals to digital form.
Computer 120 is programmed in a well known manner to perform a Fast Fourier transform on the radar signal so as to obtain, for each blade, a frequency spectrum such as illustrated by waveform 140 in FIG. 7. Amplitude is plotted on the vertical scale of FIG. 7 and frequency on the horizontal scale which is divided into a plurality of frequency ranges A to H. A threshold value is established for each frequency range and these threshold values are designated TA to TH for frequency ranges A through H respectively. If the waveform 140 for any particular frequency range exceeds the threshold value established for that range, the computer will output a signal indicating an alarm condition for a particular blade in a particular blade row. In response to this alarm signal an operator may take appropriate action or the signal may be provided to automatic control equipment for governing the turbine.
In a preferred embodiment the computer is operated so as to average the radar signals for each blade over a predetermined number of rotations of the blade row. By way of example, therefore, waveform 140 may represent the average of 10 rotations for a particular blade.
Although in the example given only two blade rows are being examined, each with two radar sensors, it is evident that the basic system illustrated in FIG. 6 can be expanded to accommodate any desired number of blade rows with each having one or more radar sensors. In addition, for a double flow type turbine illustrated in FIG. 2 blade counting circuits 70 and 71 may be additionally used to designate primed counterpart blades as well, in which case additional radar sensors and their respective gating circuits would be provided and controlled by computer 120.

Scholarship Tips
As you research outside scholarship opportunities, keep these tips in mind:
- Make sure you meet all eligibility criteria before you submit an application.
- Complete the application in its entirety. Don't leave any item blank. Make a note on the application why it may not apply to you or indicate "Not Applicable".
- Follow directions and provide everything that is requested.
- Write a concise essay. Be as personal and specific as possible. Be creative.
- Neatness counts. Make copies of the forms you receive and use them as working drafts. Once you have the final version, type it or print it neatly and legibly.
- Keep track of deadlines.
- Proofread the entire application before mailing it.
- Make a copy of the entire application for your records.
- Be wary as you search the Internet, and be careful of solicitations you receive in the mail from places that "guarantee" you'll receive scholarships if you pay a fee. Each year many families fall prey to scholarship fraud and scams. The Federal Trade Commission warns consumers to be alert for companies that make guarantees or ask for money or credit card numbers. If they are promising something that seems too good to be true, it could be a scam.

To me, the only thing better than winter is fall, and that's mostly because it's the forerunner to winter.

Phil Rykhoek
Thank you, Jack. I'm happy to report we're off to a great start this year, we exceeded the consensus expectations again this quarter and that was largely due to solid tertiary production growth and we also had some very good oil price realizations. Our tertiary production increased 4% sequentially quarter-over-quarter and 17% higher than it was a year ago or first quarter of 2012. Craig is going to review that in more detail, but in summary, things are all looking good.
With a strong start, we're effectively increasing our 2013 production guidance and are expected to be in the upper half of the previously estimated ranges. In addition to the strong production growth, we also set a record for the highest ever oil premiums relative to NYMEX, largely due to the change in our production mix as we head a higher percentage of Gulf Coast crude with the sale of Bakken. With our premium price realizations at 93% crude oil, I mean [ph], our operating margins remain strong and among the highest of the peer group.
This quarter was a bit of a transition quarter for us, particularly with regard to production as we sold the Bakken assets in Q4 and get close on the Conoco and Cedar Creek Anticline assets until this -- with those funds until the end of the first quarter. Even though we had an agreement to purchase these assets in early January with an effective date of January 1, for revenue and cost purposes, we are not allowed to book production until transaction closes. While we got -- while we think it's record production, we did get the economic benefit of the first quarter net cash flow from these properties as a downward adjustment to the purchase price.
This temporary decline in total production quarter to quarter as we saw the timing of these deals was with the primary reason for lower revenue and income and flat cash flow if you compare sequential quarters. Next quarter production should be back to Q4 or higher. And Mark is also going to provide you with several pro forma numbers so you can see what the first quarter would have been had we closed on January 1 instead of the end of March.
Another notable achievement we've had is we recently began receiving and using CO2 from 2 manmade sources of the Air Products plant in Texas and Potash Corp.'s plant in Louisiana. These projects are expected to provide some 70 million cubic feet of CO2 per day to our Gulf Coast region and tertiary operations and illustrate our unique ability to use and store CO2 underground that would otherwise be released to the atmosphere. We remain encouraged by the opportunities that we see to further expand these anthropogenic or man-made CO2 supplies in the coming years.
In the Rocky Mountain region, our tertiary offerings are making progress as we expect to see our first tertiary oil production on this area later this year. We began filling up our first CO2 pipeline, the Greencore pipeline, in that region with CO2 from ConocoPhillips' Lost Cabin gas plant and expect to begin injecting CO2 in the Bell Creek Field right there on the Montana well border in the next month. We'd anticipate tertiary oil productions of field probably late third quarter.

No. 12/730,148, all three of which are incorporated by reference.
The invention relates generally to electromechanical door locks, and more particularly to electromechanical door locks having an electronically controlled clutch mechanism and a mechanical override mechanism.
Keypad locks are becoming widely accepted in the residential market. However, many of the locks currently in the market are too large to fit with storm doors or are too bulky to provide good aesthetic appeal. A further barrier to customer acceptance occurs in designs that require additional holes to be drilled into a door in addition to the standard residential bored door prep. These deficiencies deter customers from upgrading their traditional mechanical locks to digital keypad locks. Therefore a need exists for a keypad lock that overcomes theses known installation problems.
Additional problems associated with electronic locks derive from different and conflicting goals for various parts of the lock. For example, the height of a keypad lock cannot be so high that it can no longer fit the space between the main door and the storm door. A lock suffers cosmetically as this height grows; low profile locks are more readily accepted and desired than relatively high profile locks. This preference for low profile locks is in direct conflict with a goal of allowing a standard key cylinder to provide a mechanical override means for the consumer to gain entry when the electronic functions of the lock are not available or desired. The conflict is also related to the relatively long length of standard key cylinders in relation to a typically desired low profile lock thickness or height. Often the cylinder is more than two times as long as the desired lock thickness.
This conflict is further exacerbated by a need or goal of having no new holes in the door in addition to the standard residential door prep. The space under the relatively shallow thickness of the escutcheon and in the 2⅛ inch diameter hole are the only spaces that can accommodate the lock components such as the cylinder, latch bolt, transmission parts, clutch parts, keypad, PCB, battery, passage mode switch and others.
A digital keypad lock incorporates several mechanisms and has three main components. The first component is a mechanical transmission that functions to transfer the input torque generated by rotating knobs or levers on either side of the door to the bolt or bolt latch that secures the door. Second, an electro-mechanical clutch mechanism is used to engage and disengage the transmission system so that input torque is allowed to be transmitted to the bolt latch only at the appropriate time. The third component of the digital keypad lock is an electronic programmable controller that receives input signals from the keypad or other known input devices. It performs credential checking and initiates commands to activate the electromechanical clutching in response to an authorized credential being presented.
The electro-mechanical clutch mechanism typically includes a directly actuated locking member or a clutch mechanism that connects and disconnects an exterior thumb turn or an exterior handle. The clutch mechanism also typically includes a movable member that releasably couples with the thumb turn or exterior handle, and an electronic actuator that controllably displaces the movable member in response to control signals from the electronic programmable controller. The clutch mechanism typically operates in response to an authorized input, such as a code entered in a keypad or by a swipe card. The authorized input is typically received by the controller, which then generates and transmits a control signal to the actuator that in turn operates the movable clutch member.
The transmission of input motion from the thumb turn or lever to cause the desired effect upon the door securing bolt is performed through the coordination of all the moving parts in the system. All these parts must be synchronized in motion throughout the entire operation cycle, from the time the input thumb turn or lever is activated until the time all of the components return back to their home position. Non-synchronization in any one of the moving parts may cause the lock to not function as intended.
For keypad locks utilizing levers a pre-defined, at-rest orientation for each thumb turn or lever is typically included, and with a horizontal orientation. When the levers sag or otherwise are out of adjustment, the transmission will cause the clutch elements to become misaligned. In this case when a valid code is presented to the controller and the electromechanical clutch is commanded to engage, the latch will fail to respond to the turning of the lever because the clutching elements were not in alignment and ready to receive their respective engaging surfaces. This problem can hinder the locking and unlocking functions, as well as cause security and safety concerns for users.
Such door locks also typically include a mechanical override mechanism that is intended to be used when power is lost to the controller, or when the controller or other electronic component malfunctions. Examples of such conventional electromechanical door locks are described in United States Patent Publication 2007/0157684 entitled "Manual Override Mechanism for Electromechanical Locks".
The locks described herein address the above mentioned problems by providing cosmetically desirable, low profile keypad locks that can be installed in a standard, residential door having a standard door preparation, without any additional holes and are compatible with storm doors.
The locks described herein provide both relatively low profile cosmetic and functional traits while preserving the ability to use standard lock cylinders and door preparation.
A further benefit of the locks described herein are structures that permit coordination of the clutch so that both sides of the engaging elements are always prepared for positive engagement despite form, fit and function problems nearly always present in mechanical systems due to tolerance, clearance and other inaccuracies.
In accordance with the above, several preferred embodiments of electromechanical locks or locksets as described. They incorporate structures and functions that overcome the drawbacks of known locksets and override mechanisms. A first embodiment is a deadbolt type of lock, having a thumb turn and a clutch mechanism that includes two gear trains, one of which is coupled to the outside lever or turn and input side of the clutch and one of which is coupled to the inside lever, latch or bolt, and output side of the clutch. A second embodiment is a lever type of lock, having a lever and a clutch mechanism that includes two four-bar linkages, one of which is coupled to the outside lever or turn and input side of the clutch and one of which is coupled to the inside lever, latch or bolt, and output side of the clutch. Other embodiments are variations of the dead bolt and lever embodiments.
The preferred clutch mechanism used in the lever embodiment is adapted to engage and disengage the connection between the input axis and the output axis. A cantilever wire spring mechanism provides for engagement through the activation of the motor that drives a preferably square piston pin. The alignment of one side of the clutch to the other side of the clutch is provided by springs that bias the clutch components in their home positions so that they are accurately and precisely positioned for smooth engagement of the piston pin with the transfer hub pocket upon actuation. The preferred present clutch transfer hub system permits accurate and reliable engagement.
In the preferred lever embodiment clutch mechanism, a piston pin with a square or rectangular cross section, which is driven by a motor, is pushed into the clutch transfer hub to engage the connection of the motion. Furthermore, for lever lock type locks that have a pre-defined initial position, the mating recess in the transfer hub to which the piston pin engages has an enhanced geometry, that is, a geometry that allows for a slight angular offset of +/−4 degrees that permits engagement but with some allowance for misalignment. The preferred transfer hub has a diagonal interface engagement with the piston pin instead of an edge-to-edge face interface. A further enhancement is the use of the pin with a rectangular cross section which will allow only a single defined relationship for the engagement when considered against the range of rotation possible with the lever input. This technique prevents a false relationship of engagement that could occur with a square or other polygon where the clutch could couple the lever to the latch at the end of the lever stroke which would not allow the latch to then operate as expected and could damage the lock.
When considering lever type locks whose inputs customarily have a defined at rest position, usually horizontal, it is necessary to take steps to positively align the parts on both sides of the clutch interface to allow for the immediate engagement of the clutch and subsequent retraction of the latch as the lever is depressed. This concern is diminished in products that use a turn because there is not a pre-defined limitation to the arc of rotation; rather, the turn may free spin and once the clutch is engaged may continue to turn until the bolt is acted upon. When considering lever type locks or locks that have an inherent limitation to the degree of rotation allowed, in order to avoid an irregular or misaligned return position of the parts after retraction, and also due to parts tolerance stack-up, a torsion spring holds the clutch parts under tension, thus allowing accurate and repeatable positioning at the home position after operation of the lock. The torsion spring resides in the outer housing and functions to bias the clutch parts in the outside housing to the defined home position. This spring helps to guide these components so that they align accurately and consistently every time the parts return home after operation of the lock. This technique is not needed for free spinning inputs such as those that could be used on dead bolt type locks that use a turn input.
The first or dead bolt embodiment keypad lockset has an exterior gear train, an interior gear train, and an electronically controlled clutch for coupling the gear trains when engaged and for uncoupling the gear trains when the clutch is disengaged. When the clutch is engaged, rotation of an external thumb turn will permit the door latch bolt to be withdrawn and thus permit opening of the door. A mechanical override mechanism is included in the lockset, and the override is intended to be operated in case of electrical failure. In addition, the clutch mechanism and the override mechanism both operate through the single standard 2⅛ inch door preparation hole or bore.
The second or lever embodiment keypad lockset has an exterior four-bar mechanism, an interior four-bar mechanism, and an electronically controlled clutch for coupling the four-bar mechanisms when engaged and for uncoupling the four-bar mechanisms when the clutch is disengaged. When the clutch is engaged, rotation of an external lever will permit the door dead latch to be withdrawn and thus permit opening of the door. A mechanical override mechanism is included in the lockset, and the override is intended to be operated in case of electrical failure or user preference. In addition, the clutch mechanism and the override mechanism both operate through the single, standard 2⅛ inch door preparation hole or bore.
These and other embodiments, features, aspects, and advantages of the invention will become better understood with regard to the following description, appended claims and accompanying drawings.

The lever embodiment keypad lock 200 also has a low profile design that preferably has an exterior sub-assembly lock thickness of less than 1 inch from the door to the outside surface of the exterior escutcheon plate for aesthetic reasons. In this embodiment the cylindrical shroud 256 of the outside housing 244 extends into the existing 2⅛″ hole or bore 210 in the door. Also, conventional dead latch assembly 206 extends though a standard 1″ bore 212 along the y axis into the door from the outer edge into the bore 210. The lock 200 also has two four-bar linkages that operate, once the proper code has been entered and the lever handle 230 has been rotated, to unlatch the lock and permit opening the door, as described in detail below. The axis of rotation of lever handle 230 is offset from the axis of rotation of the spindle 336 through operation of an external 4-bar linkage that generates a parallel axis of rotation when the clutch is engaged. This external 4-bar linkage transmits input torque from the lever handle 230 through the clutch to the internal 4-bar linkage which, in turn, rotates to retract the dead latch bolt. The external 4-bar linkage translates a 45-60 degree lever handle input angle into a 90 degree output angle that is required to completely retract the dead latch bolt as will be described in further detail.
The cylinder and the inside lever performs direct drive motion to retract the latch bolt. When the exterior or outside lever is rotated, the resulting torque is transmitted to the clutch axis through a 4-bar linkage. The motor activates a piston pin to engage a transfer hub that integrates both sides of the clutch to connect together. The clutch axis transfers torque from outside into the input housing. Another 4-bar linkage connects the clutch axis to the cylinder main drive axis that in turn causes the latch bolt to retract.

Hole or bore 220 is sized and positioned to accommodate a conventional cylinder 222, to which cylinder spindle or tailpiece 224, also referred to as an upper spindle as well as a drive bar, is connected with pin 226. Spindle 224 extends along the x axis and functions to operate an override mechanism as will be further described. The lower part of escutcheon plate 214 includes a hole 228 that is sized and positioned to accommodate lever 230 and associated components including spindle 232 which is also referred to as a lower spindle, shoulder washer 234 and shim or washer 236 to retain the lever 230. Timing plate 238, torsion spring 240 and c-clip 242 are also positioned about and on lower spindle 232.
Referring to
With reference to FIGS. 12 and 14-18 exterior clutch sub-assembly 246 includes an exterior four-bar mechanical linkage 260. Such linkages are well known in the field of kinematics. Also known simply as a 4-bar or four-bar, this mechanical linkage consists of four rigid bodies, referred to as bars or links, each typically attached to two others by single joints or pivots to form a closed loop. One link typically does not move, and this link is typically referred to as the anchor, ground link, fixed link or the frame. In the second preferred embodiment the exterior housing 244 is the anchor or fixed link for the exterior 4-bar linkage 260, with the first, second and third movable links referred to as spindle cam 262, cam link 264, and third link 266, respectively.
To assist in explaining the operation of the clutch mechanism sub-assembly 246 a free-body diagram of the exterior or outside 4-bar linkage 260 is provided in
Referring to FIGS. 16 and 18-21 the clutch sub-assembly 246 is preferably actuated by motor 286, preferably a DC motor, which includes axle 288, to which a worm drive, or worm gear 290 is preferably permanently attached. The motor 286 functions to rotate the axle 288 and worm drive gear 290 in a first direction to drive hairpin actuator or spring or spring actuator 292 along the x axis in a direction toward the interior or inside sub-assembly 204. Thus, the actuator 292 moves from the position shown in
As shown in
Torsion spring 332 is positioned about the first or exterior end of transfer hub or socket 330. Spring 332 and its clutch positioning leg 333, shown in
Interior Sub-Assembly
With reference to
As with any mechanical transmission, the internal transmission mechanism of the presently described lever embodiment locksets will have efficiency loss due to friction and mechanical advantage losses inside the mechanism. Traditional mechanical lever locks are designed for both outside and inside levers to be activated during the unlock function. Typically, in conventional locksets two torsion springs are used, one spring for each of the levers, to unlock the door. In preferred embodiments of the present locksets, however, the inside and outside levers are detachable, thus enabling only one of the levers to rotate while the other lever remains idle. As a result, the gain in efficiency in operation of the input lever can compensate for any internal mechanism efficiency loss.
The lost motion cam is preferably in the 3rd link of the inside 4-bar linkage, and is where the drive bar of the inside lever resides. This cam preferably has material removed to form a cavity that permits no engagement with the drive bar when the cam is being driven by the 1st linkage from the clutch axis. The preferred cam and its drive bar interface are shown in
With reference to FIGS. 12 and 24-32 additional and alternate features of the internal sub-assembly 204 will be described. The various components are positioned and held in place by inner or interior housing 360 and its interior housing cover 408, by screws 410, two of which are shown in
The lever embodiment lockset includes a passage thumb turn 382 and washer 383, positioned near the top of and extending inward of the lockset, as shown in
Referring to
Referring to
As is apparent from the above description the linkage mechanism provides proper timing and synchronization of motion among the three rotational axes, because all of the moving parts are mechanically jointed. These linkages provide benefits of relatively few moving parts because of the direct linkage between axes, and of a full-time mechanical joint. The close interface clearances allow for smooth transmission of motion.
The locksets described above are preferably provided in modules, all of which are preferably pre-assembled. It is further preferred that each of the major components has a unique orientation that prevents any mistake from occurring during assembly of the modules. During installation of the lock in a door, the inside and outside modules must be placed in a single, predetermined position or orientation with respect to each other in order to line up together and cooperated with each other. Because of this preferred feature, untrained users or customers are able to install it without difficulty.
Although specific embodiments of the invention have been described, various modifications, alterations, alternative constructions, and equivalents are also encompassed within the scope of the invention.
The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense. It will, however, be evident that additions, subtractions, deletions, and other modifications and changes may be made thereunto without departing from the broader spirit and scope of the invention as set forth in the claims.
