Patented June 5, 1906.
` Appiicaion filed December 7. i905. semi No. 290,800.
To cir/ZZ whom, it may con/cern:
Be it known that I, LEO KOPPEL, a citizen of the Empire of Germany, residing at Cologne-on-the-Rhine, in the Empire of Germany, have invented a new and useful StaplingMachine, of which the following is a specification.
My invention relates to a staplingemachine for connected staples, which machine is capable of binding materials that offer a greater resistance than paper, such as clothes, leather, felt, pasteboard, cork, and the like. The chief feature of this stapling-machine is a thick needle, which serves for piercing the materials to be bound and is provided with two shoulders near its point for supporting the respective staple and also with two opposite grooves, in which the upwardly-bent points of two benders secured on the anvil engage for bending the legs of the staple. This thick needle is secured in a plunger the lower face of which serves for detaching the staple-head from the remaining staple-heads and for forcing same downward, while the legs of the staple engage in the hole of the materials produced by the needle. Thus the legs of the staple need not themselves pierce the materials, for which they would be too weak. l
I will now proceed to describe my invention with reference to the accompanying drawings, in which- Figure 1 is an elevation of a stapling-machine, a part of the anvil being shown in section. Fig. 2 is partly an end view and partly a section through the broken line A B in Fig. l seen from left to right. Fig. 3 is a hori- Zontal -section through the same on the line C D in Fig. l. Fig. 4 shows, on an enlarged scale, a needle with the lower end of the plunger in elevation and front view; and Fig. 5 is a plan, on an enlarged scale, of a series of connected sta les.
Similar etters of reference refer to similar parts throughout the several views.
The standard of the stapling-inachine consists of abase-platea and two vertical parallel plates a a', which are fastened on the base-` plate a by means of rivets Z Z or the like, while they are kept apart by means of a distancepiece a5 or the-like. The base-plate a is provided with two flanges a* a4, on which two tables t t are secured, while leaving between them a slit. (See Fig. 3.) The anvil a is cast in one piece with the base-plate a, and its top face is a little beneath the two tables t t. On this top face of the anvil a are fastened two opposite benders u lu., the points of which are bent upward and leave between them a certain small gap. (See Figs. 3 and 4.) Sufficient space for a staple-leg should be left between the top faces of the two benders u u and the bottom faces of the two tables t t.
The two vertical plates a a are each provided with a horizontal ledge a2 and avertical guide a7 for a plunger g. A hand-lever k is pivotally connected with the upper projections of the two vertical plates a a. by means of a link lc.
A springt' of any known and approved construction serves for pressing the hand-lever 7c upward. The plunger g is pivotally connected with the handslever 7c and is provided in its lower part with a longitudinal bore, in which a needle n can be secured by means of a screw g or the like. The needle n is preferably made cylindrical, and only at its lower end it is pointed. (See Fig. 4.) It is provided with two opposite inclined cut faces, so as to form two shoulders m m above the point, and, moreover, it is provided in the two cut faces with two grooves s e, which extend through the shoulders m fm. The upwardly-bent points of the two benders fu, a are adapted to engage in thesevtwo grooves s s of the needle n. The anvil a is provided with a vertical hole a3, in which the needle n can engage.
The staple-heads c c, connected with each other by means of narrow straps c (see Fig. 5,) are provided with central openings c2 c2, into either of which the needle n can engage. The staple-heads c c are in any known manner each connected with two elastic legs b, which converge downward a little and are preferably made inwardly a little concave. They are adapted to bear on the two inclined faces of the needle 'rt and to rest on the shoulders m of the latter, as is indicated by dotted lines in Fig. 4. The two horizontal ledges a2 0.2 on the two vertical plates a a/ serve for supporting and guiding the heads c c of the staples. The front ends of these two ledges a2 a2 are at a small distance from the center line of the plunger g, so that the latter is permitted to go downward past them. A lever e is mounted to turn on a pin between the two vertical plates a a and carries a pawl el, which is arranged to slide over the series of staple-heads c c and to engage in either of their central openings c2 c2. This pawl d is provided with an arm, which normally bears on the rear face of the lever e and is pressed IOO IIO
6o be.
thereon by a spring A hooked arm h is secured on the plunger g and is arranged to push the lever e rearward on the hand-lever 7c being moved downward. Thereby the pawl d is moved through such a distance that it can engage in the central opening c2 of the following staple-head c.
The stapling-machine is operated as follows he materials to be bound are placed on the IO tables t t and a series of connected staples is introduced between the two vertical plates a a', so that their heads c c rest on the two ledges a2 a2. This series of staples is so ad- ]usted that the front staple is in the center line of the plunger g and that the pawl d engages in the hole c2 of the next following staple, as is clearly shown at Fig. 1. On depressing the hand-lever 7c the needle n will engage in the hole c2 of the front staple and 2O between the two legs of the latter, which legs b are pushed aside until they snap above the two shoulders m m. Directly afterward the bottom face g2 of the plunger g will bear on the head c and cut the straps c to divide the front staple from the remaining staples.
The front staple will slide a little down the needle n until its two legs b rest on the two shoulders m. Thereby the staple is prevented from falling off the needle n. At the same 3o time its two legs b, being inwardly concave,
will be prevented by their elasticity from slipping to either side. Immediately the needle 'n will pierce the materials, while the staple sliding upward on the needle n is soon checked by the bottom face g2 of the plunger g and is thereby introduced through the hole in the materials produced by the needle n. The upwardly-bent points of the two benders u u will engage in the corresponding grooves s s 40 of the needle n and will push aside the ends of the two legs b, and thereby consecutively bend the following sections of the latter. When the head c of the staple is on the materials, it will check the plunger g, (see Fig. 4,)
where the staple in its final position is indicated by the dotted lines. Meanwhile, the hooked arm 7i on the plunger g will. have pushed the lever e to the rear, so that the pawl d slides over the heads c c of two neigh- 5o boring staples and engages in the central opening c2 of the following staple, as is indicated by the dotted lines in Fig. l. On again releasing the hand-lever 7c, it will be returned to its upper position by the spring i, or the hand-lever 7c may be moved upward and be 5 5 front staple is in the center line of the plunger g, when it will be ready for the following operation.
The stapling-machine may be varied in many respects without deviating from the spirit of my invention.
What I claim as my invention, and desire to secure by Letters Patent, is-
l.
