Abstract
A relatively small desk-type stapler is disclosed which both forms and drives the staple from a belt of staple blanks retained in a removable cartridge. The stapler includes a driver, a former positioned to be driven by the driver, a former block and a sheath, all of which ports are held to a stationary stapler head by means of a single spring. Power to drive and form the staple may be provided by an electric solenoid. A simple anti-jam means is provided by the interaction ofthe driver, the former, the former block, the sheath and the stapler head.
Claims4
A staple forming and driving tool for forming staple wires fed from a staple belt into staples and driving such staples into a workpiece comprising:
- (a) a lower housing unit having power supplied thereto;
- (b) an upper housing unit having a block base unit, a vertical front sheath, a belt cartridge, a forming and driving unit and a solenoid for driving the forming and driving unit therein;
- (c) electrical connector means for connecting the solenoid to the power source;
- (d) insulating means insulating the solenoid and the electrical connector means;
- (e) a front sheath mounted on the block base unit;
- (f) forming and driving means being configured and the block base unit being configured to form a passageway between the front sheath and the block base to permit reciprocating movement of the forming and driving means between the block and sheath;
- (g) the block base unit having an opening therein for receiving a staple belt;
- and
- (h) the cartridge means having a chute portion insertable into said block base opening to restrict the size of the opening and to provide limit means for limiting upper movement of the belt during operation.
