'STAPLE-BEMOWR.

Application filed April 29, 1921.

Z '0 alZZ whom it may concern Be it known that 1, JOHN hllu'rn, a cit-izen of the United States, residing at Non walk, county of Fairfield, State of Connecti cut, have invented an Improvement in Staple Removers, of which the following is a specification.

This invention relates to the class of machines for fastening sheets of paper together that take staples in strips and drive them singly, and the object of the invention is to provide a device by which the staple strip can be readily removed should the machine become clogged. A. further object is to provide a device of this character that will be simple and of negligible cost, and at the same time dependable and easy to use.

In the drawing, forming a part of this specification,

Figure l is a longitudinal section of a known type of stapling machine, showing my staple remover in position to withdraw the staple strip;

Fig. 2, a perspective View of the staple remover; and

Fig. 3 is a perspective view of a staple strip.

In said drawing, 1 represents the base of a machine having pivoted thereto at one end a frame 2 by means of a pin 3. In the frame is the guide bar 4i along which the staple strip is fed to a plunger 5 which severe the staples singly from the strip, as in attaching sheets of paper together. 6 is a spring acting to hold} the plunger in the raised or inoperative position. On the plunger is a lug or step 7 that cooperates with a dog 8, pivoted to the frame, to feed the staple strip through the medium of a feed pawl 9, nor mally pressed against the strip by a spring 10.

The staple remover 11, as shown in Fig. 2, consists of a strip of metal preferably having a thumb piece 12 at its rear end, a head 13 at its forward end, and bent down claws 14 adjacent to the head. In operation, the remover is inserted along the top of the guide bar and above the staple strip until the head passes under the operating end of the feed pawl a sufiicient distance to prevent the pawl from re'ngaging the staple at the right end of'the strip. The resistance of the pawl will press the claws tightly against the strip and. muse them to engage Specification of Letters Patent.

Patented Nov. 15, 1921..

Serial No. 465,366.

the device herein described to withdraw the staple strip, which may then be repaired or another strip inserted in its place.

It is not necessary that a bar, such as shown in the drawing be used. It is suitici'ent if the device has a head corresponding to that shown at 13 that will lift the operatin end of the feed pawl and has a claw or claws adjacent thereto in position to take hold of the staple strip suiiiciently to permit its withdrawal.

Having thus described my invention, I claim:

1. A device for withdrawing staple strips from a stapling machine including a handle adjacent one end, a head adjacent the opposite end and adapted to render the feeding mechanism inoperative, and means adjacent said head for engaging a staple strip to be withdrawn.

2. A device of the class described comprising a bar having a thumb piece at one end and a head at the opposite end, and means adjacent the head for engaging a strip of staples to be withdrawn.

3. A device for withdrawing staple strips from a stapling machine having a guide for strips of staples and means for feeding a strip of staples along said guide, comprising means movable along the guide in one direction to disengage said feeding means from a strip, and movable in the opposite direction to withdraw the strip.

4:. A device for withdrawing staple strips from a stapling machine having a guide for strips of staples and a pawl for feeding a strip of staples along said guide, comprising means movable in the same direction as the strip is fed to disengage the pawl, and movable in the opposite direction to withdraw the strip.

5. A device for extracting staple strips from feeding position of a stapling machine having a guide for strips of staples and means for feeding a strip along said guide,

co nprising an elongated body, a head at one end thereof adapted to disengage the feeding means by movement along the guide in one direction, and means for engaging the strip upon movement in the opposite direction.

6. A device for extracting strips of staples from a stapling machine, comprising an elongated body, having means designed to disengage the feeding mechanism of such machine when moved along the staple strip in the direction the strip is fed and also means to positively engage said strip upon movement in the opposite direction.

7. A; device of the class described comprising a barhaving means for rendering the feeding mechanism of a stapling ma chine ineflectivaand: means for engaging a strip of staples to be withdrawn.

8. A device of the class described comerisin means for renderin the feedin C b 23 mechanism of a stapling machine ineffective,

and means for engaging a strip of staples and removing same from the machine.

9. A device for withdrawing staple strips from a stapling machine comprising a fiat bar provided, adjacent one end, with transversely spaced projections struck up from the bar.

10. A device for withdrawing staple strips from a stapling machine comprising a fiat bar provided with a projection adapted to slide over a staple strip in one direction but to engage said strip and withdraw the same when. moved in the opposite direction.

11. A device for withdrawing staple strips from a stapling machine comprising a flat bar provided with a cut at one edge thereof, and the material adjacent said cutbent from the plane of the body to form a projection to engage a staple strip.

In testimony whereof I afiix mv signature.

JOHN MUTH.
