SPECIFICATION forming part of Letters Patent No. 468,189, dated February 2, 1892.

Application tiled June 20, 1891. Serial No. 396,884. (No model.)

.T0 all whom t may concern.-

Beit known that I, JOHN L. BUCKINGHAM, a citizen ot' the United States, residing at Hermosa, in the county of Custer, State of South Dakota, have invented certain new and useful Improvements in Wireilighteners, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in wire-tighteners and stretchers; and it has for its objects, among others, to provide an improved implement of this character which shall be cheap, simple, and durable, and most efficient in operation.

I provide the lower jaw with an extension or lip which serves as a bearing for the implement in splicing the wire. The upper face of this lip is provided with a groove extending substantiallylengthwise of the jaw for the reception of the wire to give the implement a longer hold on the wire. I provide arms which serve to prevent slipping of the wire, and back of these arms are formed recesses or depressions which allow the jaws to rest down closer on the wire near the end of the jaws, and also provide room for the twist or coils.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be specifically defined in the appended claims.

The invention is clearly illustrated in the accompanying drawing, which, with the letters of reference marked thereon, forms a part of this specification, and in which is shown a perspective view of my improved implement.

Referring now to the details of the drawing by letter, A designates one of the jaws and B the other, the two being pivotally connected together in any well-known manner, as is usual in this class of devices, and formed with handles, as usual. The lower jaw B is formed with a downwardly-extending lip Z), the outer or front face of which is concaved, as shown at a, and the upper face of the said lower jaw is provided with a groove c, eX- tending in the direction of the length of the jaw, as clearly shown. The lower jaw is also provided with the upwardly-extending arms C, between which the upper jaw is designed to work. Each jaw is formed just back of these arms with a depression or analogous provision d, which may be present upon either or both sides of the jaws, although I have shown it upon but one side.

In operation the arms C prevent the wire from slipping out of the pliers while it is being wrapped around the main wire. The groove creceives the wire and gives the pliers a longer hold on the wire. The lip b, with its concavity a, formsa rest in which the main wire lies while the pliers are being passed around the main wire to which the splice is to be made, while the depressions dallow the pliers to set down on the wire nearer the end thereof, and also when first starting on the splice giving the coils or twist room to form in the recess thus formed when the instru;

ment is closed.

Some of the features of construction above specified may be employed Without the others.

The device as a whole is simple, cheap, and durable, and in practice has proved most eicient for the purpose for which it is intended.

What I claim as new is l. Pliers consisting of two jaws pivotally connected together, one formed with arms to embrace the other and one formed with a concave lip at its outer end, substantially as specified.

2. Pliers consisting of two pivotally-conf JOHN L. BUOKINGHAM.
