Y 0F GARLS'TADT, NEW JERSEY.

.Letters -latent No. 104,872, dated June 28, 1870.

The Schedule referred to in these Letters Patent yand. making pari'. of the same o all whom it may concern:

Beit known that I, EDGAR MURRAY, of the city and State of New York, have invented and made Ian Improvementrin Nippers for Cutting lVire, and the following is declared to be a full and correct description of the same.

My invention relates to the nipping instrument used in cutting wire by hand, and consists in peculiar c onstruction and arrangement, whereby the cutting-edges are in a very convenientposition for luse, a powerful leverage is obtained, and the cutters are placed in said instrument so that they can be removed with facility, either for sharpening or for the intrmluction of' new cutters.

In the drawing-- Figure 1 is an elevation of the said nippers, as opened;

Figure 2 is a similar view, as closed, with the handles partly removed;

Figure 3 is a sectional plan at the line :1: .'v; and

Figure 4 is'a view ot the cutters, detached.

a b are the lever-handles of the instrument, and c is the fulcrum-pin for the same.

At the outer and short end ofthe handle a, a head, d, is formed, and said'head is-recessed for the standing or stationary cutter c, which is held in place by the pin or screw jl' A The head l is also provided with the slotor opening g, for the block h-to slide in.

rllhis block h is'connectcd with the lever b by the pin e', and-said block is between and guided by the lianges l l of the lever b. The outer end of said block h is formed as a cutting-edge, and, as it is necessary for said block and cut-ter to lmoved but a short distance to cut or nip the wire placed between it and the standing cutter c,tl1e arc of circle upon which the pin i moves, when the levers are operated, to cut the wire, will cause said block and cutter to move in almost a-straight line towardthe standing cutter e, and' separate the wire witha direct out.

By removing the pins fr', the-cutters can be taken out for sharpening, or for the introduction. of new ones. By this construction sufficient power can be easily exerted, by the hand, for separating wire, because the iianges lZallow of' the fulcruln-pins t' c being but a little distance apart. The wirevcan be laid .into the opening between the cutters and itsposition adjusted, or the instrument can be placed over the wire, and, the cut be direct and between the parallel cuttingedges, there is not any tendency to slide or move the wire as the cut is made.

I do not claim a stationary cutter attached to the jaw of' one lever, and a moving cutter operated by a second lever, as these are coxnnion. In my nippers, the jaw g being formed in the head d, and receiving the sliding cutter h, the parts are very compact and strong, and the fuleruni c of the lever b' passes through a portion of the head (l, and the anges l l serve to hold the cutter hI in place, as well as to receive the pini, thereby facilitating the construction of the irnplement, and the sharpening of the cutters.

I claim as my iliiention- The improved tool herein described, consisting` of the piece constituting the handle and head a d, the piece constituting the handle and head b l, and the vcutters e h, said cutters being located in recesses-in the head d, the bifurcated head l embracing the head d, and pivoted thereto and to the cutter 71, all as shown and described.

Dated February 2l, A. D. 1870.

EDGAR MUR-RAY.
