, ting and bending wire; and my principal object is to provide pliers of this. character with means for cutting a wire when held at the side ofthe pliers, and to so construct the jaws that the severed end of the wire will be gripped between them when the wire is so positioned.
A further object is to so form the jaws as to combine with this wire cutting feature means for gripping the wire transversely between the jaws, for bending and otherwise manipulating it; and to also provide means for gripping and turning bolts and small. pipe between the jaws, said jaws being ma terially strengthened where the serrated wrench grooves are formed. And 'a still further object is to provide a simple and strong tool, in which will be combined features adapting it for general use.
I attain my objects by constructing the pliers in the manner illustrated in the accompanying drawings, in' which-.-
' Figurel represents a side view, with a wire shown in position after being cut; Fig. 2, a plan view; and Fig. 3, another side view, showing the tool as applied for pulling nails.
Like letters of reference designate like views.
The'pliers comprise two parts A and B, fastened together in the usual manner by a pivot pin, and provided with-tapering jaws beyond the joint circle. These jaws, upon each side, are provided with rearwardly which projections terminate at-the joint circle in transverse cutting knives, C and D. Just forward of these out- I provide oppositely disposed recesses, preferably in the form of curved grooves E, E, which pass transversely across the jaws. These recesses provide space between the jaws for the operation of theknives upon a wire placed between them, and the forward edges of these recesses at F provide means for firmly gripping-the severed-wire between theijaws. By serrating bolts, etc., of small diameter;
these grooves I give to the tool an additional I function, namely, that of a pipe wrenc Adjacent the outward ends of the jaws, I provide small transverse grooves G, G, the jaws between said grooves G and the serrated grooves E being provided with flat gripping surfaces. As so constructed thepliers, whichever side up they may be grasped, are adapted to have a wire, as H, held alongside and severed between the knives C and D into the two parts H and H, as shown in Figs. 1 and 2; the part H being immediately gripped between the jaws where they come together at the point F and held therein, while the part H may be caught in the hand which grips the pliers; thus retaining both ends of the wire in posi-v tion'to be further conveniently handled and manipulated. Byproviding the jaws with the tapering side flares the knives are very materially strengthened, so that wire of large gage may be readily cut therewith without fear of breaking the knives; the outward end of the jaws being maintained at a width sufliciently narrow to adapt the tool for conveniently handling wire, etc.,
between the jaws at this point. By combining the serrated grooves with the jaws at the point where they widen out to form the cutting knives, I am also enabled to provide a powerful and effective wrench for pipes, the width of the jaws at this point permitting a very considerable strain to be put upon the pliers without fear of breaking the jaws. By further combining with the jaws the transverse grooves G adjacent their outward ends, I provide. simple and effective means for gripping a wire,(as indicated at I, in Fig. 2), for bending or otherwise manipulating it; and by means of this groove I am further enabled to adapt the pliers for pulling or positioning nails, and the like, as illustrated in Fig. 3.
I thus provide a convenient tool combining features which adapt it for general purposes, as well as for the special uses herein set forth; said tool being made exceptionally strong and powerful, without rendering it awkward or inconvenient to handle.
