| A reproduction machine having a document scanning system has an improved recycling clutch for operating the system. The clutch has a rotatable input plate and a rotatable output plate. A pawl pivotally mounted on the input plate is biased into engagement with a notch on the output plate. A rotatable timing pulley driven by the input plate periodically contacts the pawl to disengage the latter from the output plate to effect release of the clutch at intervals greater than a revolution of the input plate. An arcuate ramp maintains the disengagement of the pawl from the output plate for a sufficient length of time to permit rotation of the latter in the reverse direction greater than one revolution via a biasing spring.

| When a cycle selection button is depressed, it causes a selected wire to be torsionally stressed to cause the selected pin to be biased downwardly against the surface of the rotary disc. The disc is carried by the timer shaft which is moved outwardly during the selection/positioning operation. The disc has various radially and circumferentially positioned holes into one of which a selected pin may drop to thereby correctly position the timer at the start of the selected cycle. Three holes are provided in the disc on the radius of the ''''soak'''' pin and a masking arrangement covers or uncovers, as the case may be, the ''''soak'''' holes so only that hole which properly combines with the selected cycle is operative. The masking arrangement is actuated by one of the possible cycle pins. Therefore, a ''''soak'''' period may be selected to precede any of a number of cycles while employing only one ''''soak'''' button and one ''''soak'''' pin.

| A device for connecting and disconnecting electrical or mechanical functions in a continuous sequence, comprising a cam shaft the cam means of which bring about said connection and disconnection, respectively, upon rotation of the cam shaft. The cam shaft supports a toothed disc cooperating with a toothed segment rotatably mounted on a second shaft, running in parallel with the cam shaft, on which second shaft is also supported a disc element cooperating with a wheel mounted on the cam shaft. Immediately upon rotation of the cam shaft, a tooth on the toothed segment will move the toothed disc for displacement of the cam shaft to operative position, wherein it switches on said functions. As soon as cam shaft rotation ceases, the toothed segment together with the disc element will bring the cam shaft back to its inoperative position of rest for disconnection of said functions.

| Two different gears mounted on the same axis and driven from a single power gear train to provide one gear as a slowly revolving timer with selectable pins triggering intermittent operation of the faster power output gear. The power output gear has a recess which interrupts its drive from a pinion rotated constantly by the gear train, and the triggering pin on the slow timing gear overtakes at a predetermined time setting and drives the output gear to effect re-engagement of the pinion therewith. An undercut portion of the gear recess radially beneath the portion of the gear teeth on the output gear disposed to be re-engaged by the drive pinion enables yielding of the gear teeth on the output gear to effect intermeshing of the gear teeth thereof with the gear teeth of the drive pinion in the event of conflict. The hub of the output gears extends axially through the slower timing gear and has a knob thereon for manual turning of the output gear during manual servicing, and the drive pinion is axially movable to disengage the same from the output gear during such manual servicing. The slow timer gear is spring biased axially to operative position and is manually movable axially against the spring and away from the output gear to free the timer gear from the gear train and provide for pre-setting the time of day for triggering or initiating operation of the output gear. A spring biased arm on the output gear is engageable by a pin on the timer gear to initiate re-engagement of the output gear by the drive pinion, after which the output gear rotates through something less than a full revolution until the drive pinion registers with the recess therein, and the arm pivotally yields against its spring as it engages successive pins during such rotation of the output gear by the drive pinion. In one embodiment the arm is withdrawn from the path of the pin at all times except when a predetermined fact occurs.

| A timing device controls a group of electric heaters, turning them on in sequence in response to call for heat by a thermostat and turning them off in sequence when the call for heat is satisfied. The timer has two stopping points, one with the heaters off and the other with the heaters on. A single switch controls the timer motor and is opened by a timer cam at the off and on positions. The switch is held open at the off position by an off latch and at the on position by an on latch. These latches are released by a solenoid controlled by the room thermostat. The latches are also controlled by a timer cam, the off latch being held released when the timer is in the on position, and the on latch being held out at the off position. The load switches for the heaters are also opened instantly by a second solenoid responding to an unfavorable condition. This same action releases the on latch to cause the timer to return to the off position.

| A power-transmitting gear having a space which interrupts the gear portion is disposed in engagement with a power-driven pinion. A trigger member having a peripheral gear segment is arranged in coaxial relationship on the power-transmitting gear for rotation with the power-transmitting gear and for limited rotation relative to it. A circular spring normally operates to maintain the angular relationship between the power-transmitting gear and the trigger member in a manner that the gear segment on the trigger member is positioned with respect to the gear portion of the power-transmitting member adjacent to one end of the space which separates the gear portion. The power-transmitting gear is provided with a second gear which is adapted to be meshed with a gear formed on the element to be driven. An input force applying member is movably disposed adjacent to the trigger member is operative to apply a force to the trigger member to effect its limited rotation relative to the power-transmitting gear so that the gear segment of the trigger member is moved into meshing engagement with the power-driven pinion. The trigger member being driven by the pinion effects rotation of the power-transmitting gear to mesh the gear portion thereof with the pinion. Thus, the drive from the pinion is transmitted to the power-transmitting gear that in turn operates to drive the element which it is desired to move.

| 1,137,193. Change-speed control. DR. ING. h.c.F. PORSCHE K.G. 4 Aug., 1967 [4 Aug., 1966], No. 35965/67. Heading F2D. A motor vehicle automatic change-speed gear control with manual override includes electrical, e.g. transistorized, circuits T 1 -T 5 which deliver an integrated control signal dependent on vehicle speed and engine torque demand sensed by the position of the accelerator pedal 52 to actuate a reversible electric motor 63 which positions the spool 39 of a selector valve 23 to selectively engage hydraulically actuated friction clutches 9, 10 and brakes 20, 21 operative on a planetary gear set 2 to shift the gear. Gear arrangement.-The engine is connected via a torque converter 1 to the input shaft 8 of the change-speed gear-box comprising two planetary trains 2 having a common sun 12. The gear output shaft 17 is fast with the ring gear 16 of one train and the planet carrier 15 of the other train. For two-way first a clutch 9 is engaged to clutch the ring gear 13 to the input shaft 8, and a brake 21 is applied to planet carrier 18. For two-way second, the train 13, 15, 12 acts alone; the clutch 9 remains engaged and the sun 12 is held by applying a brake 20. For direct top the clutch 9 and a clutch 10 clutching the sun 12 to the input shaft 8 are engaged to lock the train 13, 15, 12. For reverse, the train 16, 18, 12 acts alone; the clutch 10 is engaged, and the planet carrier 18 held by brake 21. Clutches and brakes.-The band brakes 20, 21 are each applied by supplying pressure fluid to pistons 30, 32 and the disc clutches are engaged by fluid actuated annular pistons. Venting valves, as shown at 33 for brake 21, and including a throttle 35 are provided for each of the brakes and clutches to provide smooth gear changes. Electrical circuits and motor.-An inductive speed sensor 50 senses the impulse sequence of the output bevel gear 3 to produce a signal dependent on the vehicle speed. The signal is received by an amplifier T 1 and limiter T 2 and passed to an impulse former transistorized circuit T 3 which converts the signal into a control voltage and also receives a signal from a potentiometer 51 connected to the accelerator pedal, the two signals being integrated in transistor circuit T 4 and amplified at T 5 . Two manually adjustable trigger circuits A, B, adapted to fire at different voltage levels corresponding to the 1-2, 2-3 shift points receive the integrated signal. The vehicle battery 58 supplies the electrical power through a voltage transformer 59 which prevents fluctuations in the battery output. A switch 61<SP>1</SP> is opened for manual gear changes. The electric motor 63 includes a screw-threaded spindle (66), Figs. 2-4 (not shown), received in a similarly screwthreaded hollow member 65 held against rotation and abutting the shift collar 41. A current rail (68) and balancing resistance (64) are spaced parallel to the member 65 and are interconnected by an electrically isolated conduction loop (67) so that, on energizing the motor 63, the spindle (66) rotates, moving the member 65 axially until the effective voltage on the motor drops to zero because of the feedback to circuit T 6 produced through the loop (67) and balancing resistance (64). Axial movement of member 65 for upshift therefore moves the spool 39 against the spring 40, and for downshift allows the spool to follow under the action of spring 40. Operation. Automatic.-With the switch 611 in its closed position, the manual gear lever 43 is moved to its first position moving the spool 39 of valve 23 against spring 40 into its first position, an engine-driven pump 36 supplying pressure fluid to the respective clutch and brake to engage first gear. With increasing speed on depressing the accelerator pedal, the trigger circuit A will fire actuating motor 63 to move the spool 39 to produce a 1-2 shift, and, on further speed increase, trigger circuit B fires producing a 2-3 shift. The gear lever 43 will stay in its first position during the automatic shifts due to the lost motion pin-and-slot connection 45 between link 46 and lever 44. Manual.-By depressing pushbutton 61 on lever 43, switch 61<SP>1</SP> is opened, breaking the electrical circuit and allowing full manual operation. The pin of the lost motion connection abuts the end of the slot to allow upshifts by moving the gear lever 43, and the spring 40 again causes the spool 39 to follow the gear lever on down shifts. A spring detent 48 holds the lever 43 in its selected position. | ||||||
