Abstract: 648,343. Ticket-cancelling machines. BELL PUNCH CO., Ltd. Jan. 30, 1948, No. 2893. Convention date, May 2, 1947. [Class 106 (iii)] A ticket-cancelling machine for severing the patron's portion or portions of a ticket or ticket strip from the stub portion or portions thereof comprises a member having a longitudinal opening providing a channel of sufficient length to receive a ticket strip comprising a plurality of interconnected ticket units, a plurality of spaced fingers disposed substantially in alignment adjacent to the inner longitudinal edge of said channel, a movable support for mounting alternate fingers to cause conjoint movement of all such fingers, and a second movable support for similarly mounting the remaining alternate fingers, a knife for severing the patron's portion or portions from the stub portion or portions thereof, and means for actuating the knife when any adjacent fingers are moved by the ticket. The ticket or tickets to be severed and counted are placed on a tray 191, Fig. 2, from which they are pushed into a channel 19, Figs. 1 and 6, between two plates 22 and 23. The remote edge will abut at least one of a series of depending fingers 25 carried by a shaft 26 and will also abut one of a series of upstanding fingers 30 carried by a shaft 31. The shafts 26, 31 are thereby slightly rocked and effect closure of two switches 33, 35, Figs. 6 and 15, in series. A relay 75, Figs. 2 and 15, is thereupon energized and a lever 73 is rocked away from arresting engagement with the ratchet- and-pawl 65, 66 of a one-revolution clutch controlling the main shaft 60. At the same time a circuit to the motor 51, Figs. 2 and 15, is established and the motor drives the main shaft 60 through a worm and worm-wheel 56. A drum 43 on the shaft 60 is rotated and belts 40, 41 which surround this drum and a drum 42 are set in counterclockwise motion. A heart cam 102 then effects downward movement of an arm 105 carried by a shaft 110, Fig. 1. This movement is transmitted by an arm 107 and links 109, 112 to two bell-cranks 113 which through rollers 115 effect vertical downward movement of a plate 94 which carries a knife 36, Figs. 1 and 6, which severs the ticket or tickets. A pin 142, Fig. 2, on the cam 102 moves a pawl 143 to release a wheel 135 which is in the train of gearing from a wheel 45, Figs. 1 and 7, to a counter 46. The shaft 129 and the above gear train thus freed are rotated back to starting positions, as determined by a stop, by a coiled spring (Fig. 14, not shown). The teeth 50 of the wheel 45 project into the ticket channel 19 so that as the ticket strip is fed to the right, Fig. 1, by projections 44 on the belts 40, 41, the wheel 45 is rotated and the counter 46 therefore registers the number of tickets which have been inserted. As the shaft 129 of the wheel 45 rotates a contact segment 161, Fig. 15, rotates so that circuits are established to as many lights 146, Figs. 1 and 15, as there are tickets, so that the number of lamps 146 which light give a visible indication of the number of tickets. During the rotation of the main shaft 60 a holding circuit to the motor 51 is established through relay contacts 183, but at the end of a complete revolution of the shaft 60 this circuit is broken at contacts 176, 177 by a cam 184 on the shaft.
