Abstract: 536,296. Ticket issuing machines. FREEDMAN, B. H. Nov. 7, 1939, No. 29577. Convention date, Sept. 2. [Class 106(iii)] In machines in which the feed of the strip is controlled by selectors whereby the length of the strip may be regulated according to number of grouped tickets, printing means is provided operatively associated with such selector, or common printing means selectively operated by each of them. To issue a single ticket the most forward key 38 is depressed and its corresponding selector member 44 rocked so that the projection 50 extends across channel 56. The arm 34 is also depressed and latching lever 26 moved from beneath projection 24 on lever 22 thus releasing a pin 20 as the clutch lever 16 which urged by a spring 18 engages the teeth of clutch member 12. As the arm 34 moves downwardly, the plate 136 is depressed bringing its tail above lever end 150 and either directly or through the intermediate plates 136 of adjoining units closing switch contacts 147, 149 to start the motor. This now drives the shaft 6 and through wheels 8, 10 the clutch 12 imparting a counter-clockwise movement to cams 112, 114 and eccentric 58. The cam 112 immediately acts on a roller to withdraw the projection 104 on pivoted lever 102 from the teeth of pinion 96. The eccentric 58 also rocks the pivoted yoke 60 counter clockwise and through link 64 guided by pin 66 and slot 68 moves the bar 70 to the left. When the bevelled head 72 of the bar 70 engages the projection 50 of the actuated selector 44 the bar pivots about the pin 66, the roller 74 forcing down the lever 76 to disengage its end 80 from the slot in member 82 into which it projected. The rack 98 at the same time is moved to engage pinion 96 and the latter having been released, movement of the bar further to the left drives wheels 96, 86 to feed the strip in the guide 5 the pins 88 engaging holes therein. For a single ticket, the bar 70 moves to the left sufficiently to feed a length for one ticket, the movement ceasing when the eccentric 58 reaches a forward dead-centre position. This movement to the forward deadcentre position is determined by the position of the selector member 44 before the rack engages the pinion. During that portion of the rotation of eccentric 58 where the bar is scarcely moved, the cam 112 engages the follower ends 152, 30 of levers 148, 26. The former engagement causes projector 150 to come under the tail of lever 136 and prevent the switch opening, while the latter lifts arm 34 and restores selector and key. The forward end of bar 70 is thus released by the selector just prior to the dead centre position of eccentric 58. Projection 80 is now riding upon the periphery of 82 and does not raise bar 70 immediately. When the projection slips into a notch, the bar 70 is rocked counter-clockwise by lever 76 disengaging from pinion 96. After this, the roller 110 is released by cam 112 and the pinion 96 locked by detent 104. The reverse movement of the bar 70 now occurs, the teeth 98 clearing wheel 96 During this period the cam 114 acts on rollers 116, 118 to impart a cutting movement to knife 130 and a retracting movement to clear a passage for the next advance of the ticket strip. As the end of the cycle is reached, the levers 26, 148 are released by cam 112. The release of lever 148 permits withdrawal of projection 150 from 136 and the return of the latter to open the motor circuit. At the same time the pin 20 is engaged by lever 22 causing the end 14 of lever 16 to withdraw from the clutch member 12. Printing. Each key has a projection 201 which through linkage 306-315 actuates a pin-and-slot guided slide 317 a finger on which engages an arm 322 on shaft 323 on which the type wheel is fixed. A slot and pin guided vertical bar 328 is provided with a pin 332 extending across all. fingers 321. The lower end of the bar is connected to the bar 70 by a pin extending through slot 333. During a cycle all fingers 321 will be pulled down, but only the one moved forward will actuate an eccentric 324. Upon downward movement of bar 70, the wheel selected will be rocked into position to impress the ticket strip. Inking. An ink fountain 334 has roll 335 which through rolls 336, 337 transfers ink to type wheels 325. The ink rolls and impression roller 342 are driven through gears 338, 339 from shaft 84. The type wheel turns once for each patron and if ticket is intended for two patrons the numeral '2' will be impressed twice thereon. Ticket strip. The strip is divided into colour markings shown shaded at 359 with a longitudinal tear-defining line and is provided with with pin perforations 358. The white portion is retained and stacked for checking. In a modification only the last ticket on the delivered strip has the number of patrons printed on it. In this form a single printing wheel is used, set according to the number selected, printing occurring first before the ticket is fed to discharge. A lever moved differentially by the keys is connected to a single type wheel returned by a spring. U.S.A. Specification 2,103,730 is referred to.
