WILLIAM R. HORSLEY, OF COLUMBIA, ASSIGNOB TO JOHN B. OLOUGH, OF NORTH AMHERST, OHIO.

DEVICE FOR STRETCHING WIRE.

SPECIFICATION forming part of Letters Patent No. 233,619, dated October 26, 1880.

Application filed June 7, 1880.

To all whom it may concern Be it known that I, WVILLIAM It. HORSLEY, of Columbia, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Devices for Stretching Wire; 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 pertains to make and use it, reference being had to the accompanying drawin gs, which form part of this specification.

Myinvention relates toa device for stretching wire; and it consists in parts and combination of parts that will be more fully hereinafter described and claimed.

In the drawings Figure 1 is a view, in elevation, of adevice constructed according to my invention and adapted to be operated by means of a lever. Fig. 2 is a top view of the same adapted to be operated by means of a tackle,

wherein a link is substituted for the lever,.as shown in Fig. 1. Fig. 3 is a perspective view of a portion of the device, representing the jaws clamping a wire.

In the said drawings, A represents a wire in. the process of being stretched B B, the jaws of my device. These jaws are pivoted at b. Theother ends of the jaws are pivotally attached to connecting-rods O O. These con- 0 meeting-rods O O, in turn, are pivotally united at E.

The inner faces of the jaws B B may be roughened, if desired, in order that they may more readily grasp the wire. They are con- 5 nected at a point near their outer extremities by a coiled spring, D. The object of this spring is to hold thejaws B Biu contact when power is removed from the pivot- E.

As shown'in Fig. 1. the lever may be fulo crumed at the union of the connecting-rods O O at E. One arm of this lever maybe made to bear against the ground or against the post to which it is proposed to attach the wire, and power applied to the other end of the lever will 5 increase the pressure of the jaws B B upon the wireAin proportion to the power applied. The greater the power applied the less liability there will be in the wire A slipping in the jaws B B.

(No model.)

In Fig. 2 a link, F, is substituted for the lever, as shown in Fig. 1. The object of this link is to afford a ready means for attaching a fall where it is desirable to do so, and where it would be more conveniently used than the leveras, for instance, in stretching wire upon telegraph-poles or other elevated places where it would be inconvenient to operate a lever.

My device will be found especially useful in the construction of wire fences, and when it is employed for this purpose I prefer the use of the lever rather than the link, as it can be more readily operated.

The operation of my device is as follows: The wire A is griped by the jaws B B at any convenient point. The short arm of the lever E may be brought to bear against any convenient obstacle, power being applied to the long arm of the lever E sufficient to stretch the wire the tension desired, when the end of the wire may be permanently attached to the post, and the gripe of the jaws B B released from the wire by separating them by hand.

The object of the coiled spring D is to hold the jaws together witlnsufticient force, that when griping the wire and no power applied upon the lever there will be enough strain to hold the jaws together with sufficient force to prevent their loosening entirely their gripe upon the wire.

.What I claim is- In a wire-stretcher, the combination, with two clamping-jaws adapted to operate as levers of the second order, and a spring connected to said jaws and tending to draw them together, of two arms having their rear eX- tremities respectivelypivoted to the jaws and their forward extremities pivoted to a draft device, substantially as set forth.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM It. HORSLEY.
