SPECIFICATION forming part of Letters Patent No. 572,808, dated December 8, 1896.

Application filed August 11, 1896. Serial No. 602,407. (No model.)

To all whom it may concern.-

Be it known that I, MARTIN KILLIAN, of Central City, in the county of Gilpin and State of Colorado, have invented a new and Improved Tool for Miners and Blasters Use, of which the following is a full, clear, and exact description.

- The object of the invention is to provide a tool especially adapted for miners use which will combine in one article knives arranged for splitting the fuse or. for cutting the fuse into lengths, together with a device for fastening the caps on the fuse, a cutter for any kind of wire, and a knife and punch, the tool being as compact as an ordinary pair of pliers and may be carried in the pocket with the greatest ease.

A further object of the invention is to so construct the knives that they may be readily removed from the tool in the event they should become dull, broken, or otherwise injured. The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to'be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the tool. Fig. 2 is a section through the jaws of the tool, the said jaws being closed; and Fig. 3 is a detail perspective view of one of the knives removed from the tool.

In carrying out the invention the tool in its entirety is shaped substantially as a pair of nippers or pliers, embracing two members A and B, each member comprising a body 10, a handle 11, and a jaw 12, the body portions of the members being of less thickness than the handlesand jaws, so that the body portions may be mounted to turn loosely one on the other, being connected by a pivot-pin 13 or its equivalent. The jaws may be in any shape, but are preferably made tapering longitudinally and are more or less triangular in crosssection, as shown in Fig. 2, their wider or base portions being arranged to come in contact. In the meeting face of each jaw a longitudinal groove 14 is produced, and these grooves are preferably segmental in crosssection and are arranged to register when the jaws are closed. Above the groove in the upper jaw and below the groovein the lower jaw a longitudinal T-slot 15 is produced, communicating with the segmental grooves 14, and in each of these slots or channels 15 a substantially T-shaped knife 16 is introduced, the shank portion of each knife extending into the segmental groove 14 of the jaw to which the knife is applied, and the shank portion of each knife is made tapering, being sharpened to form a cutting edge 17 at that part which enters the grooves. The knives are so placed that when the jaws are brought together the cutting edges will be substantially in contact. The knives are held in place by means of set-screws 18 or their equivalents, whereby either knife may be expeditiously and conveniently removed and replaced. In the meeting faces of the said jaws, between their centers and the body portions 10 of the members of the tool, a transverse segmental recess 19 is produced, across which recesses the knives 16 are carried, and the fuse that is to be cut in lengths is entered between the jaws at the transverse recesses 19, enabling the fuse to be quickly cut as the jaws are closed without crushing the fuse. The recesses 19 are adapted to register when the jaws are closed. The outer end portions of the knives are employed for shredding or slitting the end portion of the fuse.

A semicircular recess 20 is made in the inner edge of each handle portion 11 of the tool, and the wall of each recess is crimped, as shown in Fig. 3. These recesses 20 are adapted to receive between them the cap which is to be fastened to the fuse, and as the handles are brought together the cap will be crimped firmly to the fuse. a pocket 21 made longitudinally in its inner edge, and at the rear end of one handle a pointer 23 is pivoted, adapted when not in use to enter the pocket of that handle, and this pointer is employed for making a hole in the powder for the introduction of the cap and the fuse, while a knife-blade 22 is pivoted to the opposite handle and when not in use will enter the pocket in the same. Openings 24 are made in the body portions of the members of the tool to receive a strand of wire for the purpose of enabling said strand to be out,

Each handle hasbut this form of wire-cutter does not differ from the form ordinarily used in connection with pliers or like tools.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A tool for miners and blasters use, comprising the pivoted jaws and handles, the jaws being provided with longitudinal grooves in their meeting faces and knives secured to said jaws and having their cutting edges in the same plane as the meeting faces of the jaws, whereby said edges contact when the jaws are closed, the jaws being further provided with transverse recesses or openings across which the knives extend, as and for the purpose set forth.

2. A tool for miners and blasters use, com- MARTIN KILLIAN.
