Abstract

In a conventional solenoid'operated stapling device, the source of power to the solenoid comprises a half-wave rectifier and circuitry which permits only a one-half cycle of current to go through the solenoid.

FULL WAVE CONTROLS FOR SWINGLINE STAPLER (Cont'd)

The illustrated stapler is shown with its solenoid 10 connected to a full-wave rectifier and control circuit 12 for energizing the same with full-wave current. A switch 14 is arranged to be actuated by the insertion of a set of sheets to be stapled between the driver for the stapler and its clinching anvil. The lamp 16 is arranged on the stapler and is normally energized when the stapler is connected to a source of electrical power.

The illustrated arrangement is insensitive to relatively large voltage fluctuation and is capable of stapling much larger sets of sheets than is possible with the conventional circuitry.
