Abstract

In the drawing Figure, the paper feeder assembly 4 of a copying machine, shown here with a pair of copy sheet feed rolls 5, is pivotally attached to the main frame of the copying/printing machine. This permits the paper feeder assembly 4 to be opened for servicing by swinging the assembly 4 downwardly in the direction shown by the solid line arrow. To retain the paper feeder assembly 4 in operating position, a pair of latches 8 are provided, each latch being pivotally attached by pin 9 to the side frames 10 of the paper feeder assembly 4. Latches 8 are provided with interior stops 11 adapted to engage stop surfaces 12 on the machine frame when paper feeder assembly 4 is raised and locked in position with latches 8 closed.

OVERCENTER LATCH FOR MACHINE ACCESS (Cont'd)

In the drawing Figure, the paper feeder assembly 4 of a copying machine, shown here with a pair of copy sheet feed rolls 5, is pivotally attached to the main frame of the copying/printing machine. This permits the paper feeder assembly 4 to be opened for servicing by swinging the assembly 4 downwardly in the direction shown by the solid line arrow. To retain the paper feeder assembly 4 in operating position, a pair of latches 8 are provided, each latch being pivotally attached by pin 9 to the side frames 10 of the paper feeder assembly 4. Latches 8 are provided with interior stops 11 adapted to engage stop surfaces 12 on the machine frame when paper feeder assembly 4 is raised and locked in position with latches 8 closed.

To retain latches 8 in closed position, a wire form spring 13 is stretched between pin 9 of each latch and a locating pin 15 on latch handle 16. Springs 13 include a U-shaped tensioning segment 17. When paper feeder assembly 4 is closed (the position shown by solid lines), springs 13 impose a locking bias on latches 8 which holds the latch stops 11 tightly against the stop surfaces 12 to retain paper feeder assembly 4 locked in position. To release paper...
