PLIERS FOR CUTTING ANo-cAsPm e Fuss, etc,

SPECIFICATION forming part of Letters Patent as. 287,159, dated October 23,4883.

' Application filed July 20. 1883. (No model.)

of New York, have invented a new and useful Improvement in Pliers for Cutting and (lap ping Fuse, &c., and the following is declared to be a description of the-same.

In mining and other operations where blasting is carried on the handling of fuses, cartridges, or explosive caps and cases of explosive powder is always attended with great risk, and unusual precautions are necessary to protect human life. Devices for securing the explosive cap upon the fuse have heretofore been made.

'My invention consists of a device combining the qualificationsof a fuse cutter, capper, and case-opener. 1

' My improved pliers contain a pair of handies and jaws pivoted together. Th9 handles, being made round, with parallel sides, and the ends being pointed, are used for making a hole in the blasting cartridge or case of giantpowder for the insertion of the explosive cap upon the end of the fuse. I Upon the inner surface'of one jaw of the pliers there are two transverse semicircular grooves, and upon the inner surface of the other jaw there is one transverse semicircular groove opposite to the groove in the other jaw nearest the pivot of the pliers, and there is a projecting lip also upon the end ofthis jaw, opposite to the second transverse groove in the other jaw, and

' upon the face of one jaw there is secured a plate of metal having a cutting-edge to sever the fuse. The fuse is out by the blade, and at the same time compressed in the opposing semicircular transverse grooves to a size for entering the explosive-cap. The fuse and cap are laid in the second transverse groove, and.

the lip on the other jaw is forced into the shell of the cap, near its open end, to indent the metal into'the fuse for securing the cap to tlfe end of the'fuse.

In the drawings, Figure '1 is an elevation of the pliers open. Fig. 2 is a perspective view of the same, showing also the fuse andexplosive cap, as the indentation is made in said cap: Fig. 3 is an enlarged cross-section of the fuse and cap, showing the indentation.

The handles a aare preferably made round,

with parallel sides and pointed ends a a, and 'areto be used to puncture the blasting eartridge or case of giant-powder for the insertion of the explosive cap The jaws b b and handles a (L are pivoted together at c. The jaw b is made'with t'wo transverse semicircular grooves, d (1, upon its inner face, and the jaw b is made with one transverse groove, e, upon its inner face opposite to the groove 11, and at the .end of the jaw b there is a projecting lip,j, opposite to the groove 6. The cutter blade or plate 9 is upon the jaw b,- and when the fuseis laid in the groove e and the pliers closed such fuse is cut off square by this out ter, and at the samc'time the end portion inthc grooves (Z c is compressed to the correct size to enter the end of the explosive cap it. The fuse It is now to be passed into the explosivc cap it", and the latter -laid in the transverse groove d, and the pliers are closed, the projecting lip f indenting the metal near the Open end of the cap into the fuse and securing the two together.

If desired, the pivots, 0 might be at the outer ends of the jaws b b, in which case the handles will be continuations of the. respective jaws, and in line, or nearly so, with them.

I claim as'my invention- 1. The pliers for cutting and capping fuse, composed of the handles and pivoted jaws, one jaw having a cutter and two semicircular transverse grooves, and the other jaw having one semicircular groove opposite to one of the grooves in the other jaw, and a transverse projection opposite to the other groove, substantiallyas specified.

, 2. Pliers for eutting'and capping fuse and perforating the cartridge, composed of roundpointed .handles, jaws with coinciding transverse simicircular grooves, and a cutter adjacent to such grooves, and a semicircular groove in one jaw and a projecting rib on the other jaw for indenting the cap, substantially as set forth.

' Signed by me this 13tl 1 day of July, A. D. 1883.

SAMUEL POOLE.
