Abstract

Continuous ticket stock 1 is incrementally advanced, into the plane of the paper, by feed mechanism 2 of a ticket printing machine. Each feed increment is the length of one ticket. At times it is desirable to ever the stock at intervals that produce groups of interconnected tickets rather than individual tickets. The apparatus enables selective control of the severing interval.

Selectively Controllable Ticket Chopper

Continuous ticket stock 1 is incrementally advanced, into the plane of the paper, by feed mechanism 2 of a ticket printing machine. Each feed increment is the length of one ticket. At times it is desirable to ever the stock at intervals that produce groups of interconnected tickets rather than individual tickets. The apparatus enables selective control of the severing interval.

Punched card 4 is inserted in slidable tray 3. The latter is moved to the left to a position established by stop 18. Horizontally movable hole sensing arm 5 has tip 6 which drops into card hole 19 as 3 moves to the left. Microswitch 7 mounted on 5 is thus laterally positioned with respect to ratchet 8 in accordance with the position of hole 19.

Each feed increment of 2 reciprocates drive pawl 12 to move 8 one tooth to the right from a home position established by stop 10. Antireverse pawl 13 restrains 8 from movement to the left under the influence of tension spring 11. When shoulder 9 of 8 contacts the actuator of 7, chopping solenoid 15 is activated, causing blade 16 to sever 1. At the same time, link 14 is caused to pivot 12 and 13 out of the path of the ratchet teeth. This permits 11 to draw 8 back to its home position. Thus the apparatus is set up to undergo another cycle. To change the severing interval, the position of 7 is changed through insertion of a new card.
