Abstract: 453,645. Ticket-issuing machines. HELSEL, R. H., WOLFE, C. J., and FAUST, F. J., (trading as SILENT-AMERICAN TICKET MACHINE CO.), 36, 36th Street, Long Island City, New York, U.S.A.-(Assignees of Pierson, H. L. ; 424, Senator Street, Brooklyn, New York, U.S.A.) Jan. 15, 1935, No. 1341. Convention date, Jan. 15, 1934. [Class 106 (iii)] Apparatus having key-controlled, motor-operated mechanism for issuing a selected number of tickets from a strip comprises a feed wheel or drum driven through a clutch having a throw-out member rotating therewith, and a trip device to effect release of the clutch and stoppage of the parts in a predetermined position, cooperating stop means between the key mechanism and the clutch control member being provided to govern the extent of movement of the clutch control member out of the clutch releasing position and step-by-step mechanism operating in synchronism with the feed wheel or drum to restore the control member to the clutch releasing position. The movement of the feed-wheel is intermittent in steps corresponding to ticket length and with a dwell or rest between movements in time with the operation of a ticketsevering knife. A construction is described for a number of narrow units grouped in a small space, each unit having a counter driven from the feed-wheel gear. When a key 68 is depressed, it rocks a universal bar 61, which moves a switch to start the motor which drives through a pinion 31 the clutch gear 32. The rocking of the universal bar lifts a link 56 to unlatch a pawl 51 from a selector bar 48, which then snaps forward to the position determined by the stop 72 engaging a shoulder 70 on the key lever. The release of the selector bar 48 disengages its inner end from a pin 50 and permits the clutch trip member 44 to drop and the clutch to become engaged, the clutch plate 36 being shifted to the right, Fig. 6, to coupler gear 35 and rotation being imparted to an eccentric 21, Fig. 10, to rock a pinion 20 about its sliding centre 24, 25 in engagement with the internal gear 19 of a feed wheel 15. At each ticket length of feed, the eccentric in passing over the dead centre of the sliding pivot effects a dwell sufficient for movement of the ticket-severing knife. The actuating lever for the ticket knife 128 only becomes coupled to drive the knife when the coupler 145 is lifted by a link 147 by shifting the throw-out lever 44 back to the clutch throw-out position. The key lever depressed is held by a dog 96, a lever 108 snapping under a shoulder 111 to lock a T- shaped lever 105 and hence the dog-releasing link 101. This lock is released at the end of the cycle on the return of the selector bar by engagement of a pin 55 thereon with the lower end of the lock lever. Too early release of this lock is prevented by an arm on a cam lever coming down over a pin 113 on the end of the T-shaped lever. To prevent accidental release of the selector, there is provided, in addition to the pawl 51, a locking lever engaging a notch in the selector and adapted to be released by the upwardly moving trip link after that link has tripped the pawl 51. Cushioning of the selector bar is effected by the spring-tensioned key levers 62 and by leaving the point of the restoring pawl 76 at rest on the smooth part of the bar in the stopped position of the machine, so that the releasing movement of the bar is checked momentarily, after it has travelled sufficiently to throw the switch on, by the point of the pawl 76 dropping into the first tooth 81. The pawl 51, after being tripped and the parts started in movement, is uncoupled and free to serve as a holding pawl for the selector bar by a cam swinging the trip link 56 clear of the tail of the pawl. The restoring pawl 76 thereupon carries the bar one step towards the clutch release position, and upon its recovery stroke the pawl 51 holds the bar in its advanced position. At the end of its recovery, the inner end of selector bar 48 engages pin 50 to rock the clutch trip 44 up into the operative position where, on the continued rotation of the gears, the clutch release lever 43 rides over the incline of the same to draw out the clutch and to stop the parts in the position shown, Fig. 1. The severed tickets are grasped by the purchaser, a finger lug 122 preventing the cut tickets from being accidentally pushed back into the machine.
