Unire Sfrnrns `ROBERT C. BOLON, OF LINEVILLE, IOVA.

WIRE-STRETCHER.

SPECIFICATION forming part of Letters Patent No. 554,765, dated February 18, 1896.

' Application tied June 4, 1895.

To all whom t may concern:

Be it known that I, ROBERT C. BoLoN, a citizen of the United States of America, residing at Lineville, in the county of Vayne and State of Iowa, have invented a new and useful Combined Wire Stretcher, Splicer, Cutter, and Staple-Puller, of which the following is aspeciication.

The object of this invention is to produce a simple, strong, and durable device adapted to stretch a wire beyond the post to which it is attached and to grip the Wire and stretch it with one movement of the operating-lever, to connect an eccentric-clutch therewith, whereby the device may be used as a wiresplicer to operate without engaging a post, and further to provide means for pulling staples and cutting wire.

My invention consists in certain details in the construction, arrangement and combination of the various parts of the device, as hereinafter set forth, pointed out in the claims and illustrated in the accompanying drawings, in which- Figure 1 shows the complete device in perspective in position for either stretching or splicing wire. Fig. 2 is a detail view showing the staple-puller and wire-cutting device.

Referring to they accompanying drawings, the reference-letter A is used to indicate a straight fiat metal bar having a curved lateral extension A2 adapted to engage a post or to have its tapered end A3 enter under a staple to pull the same.

At the rear end of the device is a cross-arm B projecting laterally from both sides. B2 is a stationary segmental upright on one end of said cross-arm, and B3 is a lever fulcrumed to the opposite end of the cross-arm and having a cam-face BL1 adapted to engage the upright B2 and a lip B5 arranged to overlap said upright and prevent a wire from moving upwardly above the upright B2 when clamped between the two surfaces.

C indicates an arm slotted to admit the bar A and pivoted at its one end to the lateral eX- tension A2 and having formed integral with Serial No. 551,693. (No model.)

end of said arm beyond its pivotal point is a curved projection F having a sharpened lower edge, and F2 is a notch formed in the side of the arm C adapted to receive a wire and sharpened at its upper edge to form, in connection with the projection F, a wire-cutting device.

H indicates a chain secured to the end of the bar A opposite from the eccentric wire-clutch hereinbefore described, and H2 is an eccentric -wire-clutching device of common construction detachably connected with said chain.

In practical use if it is desired to stretch a fence-wire to a post the hook B2 is passed around the post or pressed into a iiat upright, and the lever D and arm C moved toward the end of the bar in the direction of the wire to be stretched. The wire is th en admitted between the segmental upright C2 and cam D2 and the lever D moved forwardly to clamp the wire therein. A further movement of the lever in the same direction will stretch the wire, and when moved to its farthest limit the wire is clamped by the device on the end of the bar A and held until said lever D is moved rearwardly and a newhold on the wire is obtained.

To splice wire the eccentric clamping device H is connected with one end of the Wire and the other engaged by the eccentric on the bar A and drawn toward said wire in the same manner as if the device were attached to a post.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent of the United States therefor, is-

1. An improved Wire-stretcher, comprising a bar having a curved lateral extension at one end, terminating in a point adapted for pulling staples and provided with a notch on its convex edge for cutting wire, an arm pivoted to the said extension and extended across the bar, and terminating with a curved point having a cutting-edge, an upright on its top surface and a lever fulcrumed to its free end and having an eccentric on its inner end to engage said upright, and a wire-clutching device on the other end of said bar, for the purposes stated.

2. An improved wire stretcher, splicer, cutter and staple-puller comprising a flat bar, a curved lateral extension tapering to a point D2adapted to overlap the upright C2. At one adapted for pulling staples and provided with IOO a notch in its convex edge for cutting wire, with the end of the bar beyond the lateral oxa-n :mn pivotcd to said extension and provided tension, all arranged and combined substan- 1o wtlmproject-ing point havinga cutbing-edge, tisilly as and for the purposes stalled.

:in upright on cop of said arm, a lever fulcrumed to the opposite end of the zirln and ROBERT C. BOLON. having au eccentric on its top, an eccentric Vitnesscs:

clutch device on the opposite end of the bar, JACKSON UNDERHILL,

and a clutch device detachably connected DILLEN UNDERHILL.
