Patented in the German Empire on March 16, 1886.

The wire, which unwinds from the reel x, Fig. 5, is ^{pulled through the guides / and Z 1} and the round knife m over the bending block η and under the clamp benders b and b ^l , Fig. 2, after the have been set apart by toothing with connected rollers y and y ^x , which is done by setting the eccentric bolt %, around which the small roller y 'rotates, in motion by means of the crank k.

After the wire is retracted, the crank is rotated k back so far, that both rolls and y j ^'1 pinch the wire, after which it automatically introduce the same into the staple forming apparatus.

• By pressing down the footstep connected by the tension spring to the curved lever c ¹ , Fig. 4, the angle lever w is set in motion and thereby initially the tongue d, which is under spring pressure in the clamp slide c, Fig. 2 and 4 , alone moved downwards, up to the moment when it lies on the wire located between tongue d and bending block η. Then the nose attached to the connecting piece 0 / the releasable pawl e of the three-armed lever g has also arrived, FIG. 1.

By further pushing down the Füfstritts the catch E is moved laterally and thereby h the slide on which the flex-b and are b ^1, Fig. 2, is moved downward and the bracket above the Umbiegeklotz η finished bent after the wire by at Flat knife s attached to bender b is cut off. At the last moment of the pawl movement, the bending block is pulled back, to the extent that the tongue d can push the clamp downwards. Now the staple slide c hits the two bolts ρ and p ^l , Fig. 1 and 2, located on the scissors shsh, and causes the inward movement of the staple drivers t and i ¹ , whereby the staples by moving on the inclined planes q and q ^l get their lead, pushed through the box walls.

Figure 3 shows how the staple is formed and driven into the paperboard.

In the course of the movement of the staple driver, the pawl e has stepped over the nose f , which is caused by the tension springs ii which are at the same height and which lie on both sides of the connecting piece 0. In addition, during this movement, the lever α has been moved sideways by the angle lever r, with the result that the movable pawl u has gone to the opposite side and placed itself behind one of the six pins located in the roller y.

The curve lever has then reached its dead point. A further movement of the same has only to bring about the bending of the clamp legs inside the box, which happens because the stop M ¹ , which is attached to the side of the cam lever, rests on the rod s ¹ and moves it forward, which movement through the angle lever n> ^{1 is transferred} to the bending slide, FIG. 4.

When stepping back, the clamp slide c is lifted again and the tongue d of the same is just above the bending block n when the scissor bolts j? andp ¹ in the slot holes α and a ^{l assume} their original position. When the clamp slide c goes up further, the angle levers r and r ¹ , with which the clamp drivers t and i ¹ are connected, are drawn together, the movable pawl u on the lever α, which is connected to the angle lever r by the connecting piece β moved sideways and then the wire is fed into the staple forming apparatus.

Claims (1)

Pat ent. Claims:
To insert the wire into the staple forming apparatus, the mechanism formed from the pawl u, the lever a, the connecting piece ß, the angle lever r and the scissors sh. For the purpose of the automatic clamp formation of the nose / in connection with the three-armed lever g, the releasable pawl e located on the same and the springs i P formed, which the clamp bender b and b ^l , the knife s for cutting the wire and the Sets the bending block η in motion. For this purpose 2 sheets of drawings.
