Abstract

Disclosed is an arrangment for applying a light, steady slipper force in an automatic stapler apparatus which includes a rotatable, cylindrical magazine adapted for indexing movement. As shown in the drawing, a stapler head 1 is mounted on a frame 2 in an inverted position to apply staples to a collected set 3 of sheets of copy paper. Drive means having an upwardly moving element 4 and a downwardly movable clamper/clincher 5 combine to produce separation of a staple from a staple stick 5 held in the stapler container 6, driving of the staple through the stack of sheets 3 and bending of the legs of the staple to complete the stapling operation. In order to replenish the staple container 6 with additional sticks of staples, there is provided a hollow, cylindrical magazine 7 mounted for rotation of the frame 2.

STAPLE SLIPPER FORCE BY ROTARY SOLENOID (Cont'd)

Disclosed is an arrangment for applying a light, steady slipper force in an automatic stapler apparatus which includes a rotatable, cylindrical magazine adapted for indexing movement. As shown in the drawing, a stapler head 1 is mounted on a frame 2 in an inverted position to apply staples to a collected set 3 of sheets of copy paper. Drive means having an upwardly moving element 4 and a downwardly movable clamper/clincher 5 combine to produce separation of a staple from a staple stick 5 held in the stapler container 6, driving of the staple through the stack of sheets 3 and bending of the legs of the staple to complete the stapling operation. In order to replenish the staple container 6 with additional sticks of staples, there is provided a hollow, cylindrical magazine 7 mounted for rotation of the frame 2.

The cylindrical magazine 7 is formed axially with openings 8 having the general shape of staples for containing the sticks 5 of staples. The openings 8 are formed adjacent to and along the circumference of the magazine 7 and are adapted to receive a slipper element 10 movable into and out of the openings 8 for engagement with each of the staple sticks. The slipper drives each of the sticks out of an opening 8 and into the container 6 and exerts a steady, constant force upon a stick until such time as it is retracted and the magazine indexed to present another stick insertion into the stapler container 6.

The slipper is secured by way of a bracket 11 to an endless belt 12 trained around a pulley 13 mounted within the hollow cylinder 7, a pulley 14 mounted on t...
