719,055. Ticket-printing machines. LICENTIA PATENT-VERWALTUNGS-GES. Oct 23, 1950 [Jan. 10, 1949], No. 25815/50. Class 106 (3). [Also in Group XVI] In a ticket printing machine in which a driving electric motor is switched on by the introduction of the ticket, into a, receiving slot, the mechanism for switching on the motor serves as an ejector which returns the ticket directly from the slot after printing. In the apparatus, shown, when the blank ticket 1 is inserted, it pushes back a slide 2 and rocks an ejecting lever 4 connected to a guide bolt 8, carrying a locking member 9 which. is] then moved out of the path of a lever 11 fixed to an axle 16 so that the latter are free to be rocked clockwise, Fig. 3, by a spring 12 connected to a lever 25. A latch 15, also secured to, the, axle, is. then moved, out of register with a locking disc 42 and allows a spring-urged; coupling claw 18 of a one-revolution clutch to engage an abutment. 22 on a worm wheel 23. At the same time, the lever 25 moves a switch rod 29 leftward to close contacts 32. 33 to start, the motor 34 which drives, through toothed gearing 35, 36,. 37, the wheel 23 and the claw-carrying member 19 which is secured to the printing-drive-shaft 24, The member: 19 includes a cam portion 39 which, through the bolt 8 and lever 4, moves the ticket slide into position 2b so as to clear the printing position 38, and eccentrics (not shown) guide a printing table parallel to a block to print the ticket. Before the end of a revolution of the shaft 24, a cam 14 returns lever 11, and therefore lever 25, to the position shown, thus switching off the motor, and the latch 15 is returned to the clutch-disengaging position. A slot in the cam 39 allows return of the bolt 8 and ejection of the ticket under the action of springs 5. In a modification, the ticket may switch on the drive motor through photo-electric sensing means.
