Abstract

The apparatus is associated with a ticket printing machine to print a stripe of a selected color on ticket stock 1 feeding from right to left. A rack 3, pivoted at 17, supports a plurality of cartridges 10...14 containing different colored inks. Each cartridge has a felt writing nib 15 at its lower end and is normally supported upwardly, out of printing contact with 1, by a compression spring 16.

Automatic Ticket Striper

The apparatus is associated with a ticket printing machine to print a stripe of a selected color on ticket stock 1 feeding from right to left. A rack 3, pivoted at 17, supports a plurality of cartridges 10...14 containing different colored inks. Each cartridge has a felt writing nib 15 at its lower end and is normally supported upwardly, out of printing contact with 1, by a compression spring 16.

To move 3 to locate a selected ink cartridge in print position under arm 8, punched card 9 is inserted in slidable tray 6. The latter is moved leftwardly to a final position established by frame member 20. During the course of this movement, hole sensing arm 4, which is constrained to move horizontally in a straight line, scans a predetermined column of the card. Arm 4 is pivotally connected to 3 and has a tip 5 for sensing holes. When 5 drops into a hole 21, a ridge 23 in the bottom of 6 bears against 5. Such action causes the continued movement of 6 toward its final position to pivot 3 clockwise, against the bias of tension spring 22.

The position of the hole in the card thus selects the ink supply to be used for printing the stripe. Solenoid 7, activated when the ticket feed mechanism starts, causes arm 8, which pivots about pin 18, to depress the selected cartridge so that its nib contacts 1 and causes a stripe to be printed as the stock feeds. Rack 3 can be provided with appropriate containers, not shown, for enclosing nibs 15 in airtight ch...
