MINER$ COMBINATION TOOL. No. 270.315. Patented Jan. 9,1883.

UNITED STATES PATENT OFFICE.

JOHN JONES, OF OREGON CITY, OREGON.

MINERS COMBINATION-TOOL.

SPECIFICATION forming part of Letters Patent No. 270,315, dated January 9, 1883,

Application filed April 11, 1882.

To all whom it may concern:

Be it known that 1, JOHN JONES, of Oregon City, county of Olackamas, State of Oregon, have invented a Mincrs Combination-Tool; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to a novel com biuationtool for the use of miners in their operation with blasting-fuse.

The object of my invention is to provide a tool to split the fuse either lengthwise or crosswise, to cut it off squarely lI'Oil'l the coil, to press its end to receive the cap, and, finally, to press the cap tightly upon it.

My invention consists in a plier-like tool,the points or jaws of which are formed, one tlat and the other into a blade, constituting the splitting mechanism, and the flat jaw having on its rear part a small projection formed into a cutting-edge, which, with that portion of the blade which meets it, constitutes the cutter. Behind the pivot-point the meeting shanks or handles are formed with grooves adapted to tit around and press the end of the fuse, and also with other grooves havin; ribs and adapted to fit around the cap and press it lightly upon the fuse when titted upon it.

Referring to the accompanying drawings, Figures 1 and 2 are views oi my implement. Fig. 3 represents the fuse.

Blasting-fuse is a tube tilled with some combustible composition. In order to get at this composition to apply the match so that it will ignite readily, the protecting-tube should be split lengthwise at one end, as l have shown at a in Fig. 3. Sometimes, where no blastingcap is employed and the explosion is effected by direct contact with lire, it is necessary to split or cut the sides of the tube crosswise, as shown at b h in Fig. 3, so that the tire, when it reaches these cuts, may issue forth to produce the explosion.

Let A represent one half the tool, and B the other, pivoted together at O, and bearing a resemblance to the ordinary pliers. The side A has its point orjaw made flat upon its inner surface, as shown, while the side B has itsjaw made in the shape of a blade, the cutting-edge (No model.)

of which is adapted to be brought down upon the flat surface of the other jaw. By this construction the fuse I) may be split or laid open, as explained and shown, and may he cut crosswise withontentirelycutting through it. Upon the tlatjaw, near its rear part, is a projection, e, which is ground to a cutting-edge, and forms, with the blade of the other jaw, a'short cutter. In this the fuse may easily be severed from the coil or cut into desired lengths. Behind the pivot-point, in the innersidesof the two shanks or handles, which are of some width, are cut grooves in in, which, when the shanks meet, form ahole or die. In these grooves are formed ribs or beads o.

\Vhcn the cap G is fitted upon the end of the fuse itrequires to be pressed tightly thereon, making it secure and water-tight, so that it will not be damaged when used in wet holes, &c. The handles are opened and the cap fitted in the grooves in, which are then brought together and pressed tightly around it. The heads 0 press into it and form pee ripheral dents, which hold it securely to the fuse. Behind the grooves m m are othcrsm it, which are made to iitover the end of the fuse, and by compressing it prepare it to receive the cap with case.

By the use of this tool the fuse and cap may be readily prepared.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination-tool for splitting and cutting blasting-fuse, pressing it to receive the blasting-cap, and securing said cap thereon, consisting of the parts or sides A B, pivoted at O, the former having a. Hat point or jaw with a cuttin x-projection, c, and the latter having a sharp blade-like point or jaw, said sides A I5 alsohaviugbehindtheirpivot-pointthegrooves m m, with their heads or ribso and the grooves 02 12, substantially as herein described.

in witness whereof I hereunto set my hand.
