DAVID H. BAUSMAN, OF LANCASTER, PENNSYLVANIA.

WIREV-STRETCl-IER.

SPECIFICATION forming pari: of Letters Patent No. 358,831, dated March 8, 1887.

i Application led July 17, 1886. Serial No. 208,233. (No model.)

T0 all whom, it may concern:

Beit known that I, DAVID H. BAUsMAN, a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new andl useful lmprovementsin VVireStretchers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

rlhis invention relates to wirestretcbers; and it consists of a wire-clamping device with a loop-springand link, substantially as here inafter described and claimed.

I am aware that clamping devices for wirestretchers somewhat similar to that herein shown have been made before; also, that a spring-bail has been in use before in ice-hooks. Therefore l do not claim the same, broadly` but only the certain specific combination of the severalvparts fully hereinafter described.

In the accompanying drawings, similar letters refer to similar parts throughout the several Views.

Figure l represents a full front view of the machine with the jaws closed on ther wire.

Fig. 2 is a longitudinal sectional View through the line m m of Fig. l; Fig. 3, a full front view showing the jaws open, with the wire in position between them; Fig. 4, a similar view showing the application of the machine when stretching the wire on the fence.

ln Fig. 3 the jaws A A are shown open with the wire B in position between them. The jaws have eccentric concave and convex ridged faces a a', and are held in position on each other bythe rivet C, the concave and convex eccentric faces c a being adapted to grip and hold the wire B when closed on the same, as shown in Fig. l. On the upper side of the jaw A is a lug, D, projecting over the con- Vex face c, which prevents the wire B from twisting out laterally when the aforesaidjaws are closed on the same. Said jaws A A have outwardlyprojecting arms c c, through which are the openings e e, adapted to receive and fit loosely the ends of the loop-spring E, which are passed through them and bent up and around the body of said spring, as shown, forming a joint capable of standing considerable tensile strain.

The object of the loop spring E is, in the first place, to hold the jaws A A open when the holes e e in their outwardly-projecting ends are below the rivet C, as in Fig. 3, said spring having a contracting tendency, as indicated by the arrow s s in Fig. 3; secondly, to hold jaws A A closed on the wire B when the aforesaid holes e e in their outwardly-projecting faces are above rivet C, as shown in Fig. l; and, thirdly, to serve as a handle and a simple means of attaching the wire link F, the extreme ends, f of this link beingtwisted and bent down so as to withstand considerable tensile strain.

The entire operation of my construction of wire-stretcher is fully shown in Fig. 4. The jaws A A having holden the wire, the end of the lever H, which is a stout pole or piece of fence-rail, is passed through the link F, said end engaging with one ofthe fenceposts, which serves as a fulcrum for the same, enabling the operator to apply any amount of strain on the wire gripped by the jaws A A.

Having thus describedmy invention, what I claim as new, and desire to secure by Letters Patent, is

The jaws A A, held together by the rivet G, having the concave and convex eccentric faces a c', adapted to grip and hold the wire B, as set forth, in combination with the loopspring E, attached to the outwardly-projecting ends c c ofthe said jaws A A', and adapted to hold them open or closed by its contracting tendency, as set forth, and the wire link F, engaging with the aforesaid loop-spring E and adapted to receive the lever H, when constructed and operated substantially as set forth, and for the purpose described.

In testimony whereof l affix my signature inv Witnesses:

D. H. KULP, H. S. BITNER.
