BLASTING-CARTRIDGEr SPECIFICATION forming part of Letters Patent No. 542,102, dated July-2,1895. Application filed June 13, 1851, Serial No.:396,105- (No model.)

To all whom it may concern.-

Be it known that}, GERsnon MOORE PE- 'lERS, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Blasting-Oartridges, of which the following is a specification.

This invention relates to blasting-cartridges, and it will be described in the following specification, and pointed out in the claims.

Like letters refer to the same pa'rts in the several figures of the drawings, in which- Figure 1 represents a side elevation, partly in section,.of a blasting-cartridge containing a detonating-cap connected to an electric fuse. Fig. 2 is a transverse section of the same, taken on the line .1: a: of Fig. 1. Fig. 3 is a side eletridge with the compressible plug for the elec- Fig..4 is a side elevation, partly in section, of the blasting-cartridge, including the safety-fuse; and Fig. 5 isa vertical section of the sealing disk or head with therein.

The case of the cartridge is designated in the drawings by the letter A, and it may be made of any suitable material and of any proper shape, but is preferably of cylindrical shape and composed of waterproof paper or similar substance. The ends of the case may be closed by disks, preferablyof heavystraw or cardboard, cut to closely fit the internal diameter of the case,and secured thereto by glue or waterproof cement specially prepared. Instead of connecting the disks in the abovedescribed manner, which is the one I prefer, y it is obvious that they may be secured thereto in any other suitable manner. One of thedisks, called the head, and designated by means of a punch, or, rather, the stroke of the punch is arrested before it is entirely finished, so that the material being punched out is only partially pushed out and remains to form what may be termed a removable stopper, which closes the aperture during the transportation of the package and 'until it is desired to use the cartridge. This stopper is designated by the letter B and is plainly shown in Fig. 5 of The stopper may be readily the drawings.

removed and then the cartridge may be used with a safety-fuse or a blasting-barrel or an electric fuse, and in the accompanying draw ings I have shown in Figs. 1 and 4, respectively, the manner of applying the electric fuse and the safety-fuse.

\Vhen I wish to employ an electric fuse I connect wires F F to a detonating cap or primer D, insert the latter in the powder within the cartridge, and connect the portions of the wires which extend outside of the cat. tridge to a suitablesonrce of electricity, in this case said source being shown at G as a battery. The circuit is normally broken, but can be readily closed when desired, asis shown at II. I then pass a plug E, of cork, rubber, or similar material, into the aperture in the head and press it downward so firmly as to cause those portions of the wire F F adjacent to such plug to become embedded therein, whereby a tight and water-tight joint is effected.

Then I desire to employ a safety-fuse in connection with this cartridge, I use a plug I, of cork, rubber, or other suitable material, having a hole therethrough, pass a fuse K through such hole in the cork, and then insert the cork in the aperture in the head 0 and press downward so firmly as to cause the plug to tightly compress about the fuseand make a water-tight connection.

The manner of applying the safety-fuse, as above described and shown in Fig. 4 of the present drawings, is not specifically claimed in this application, but is the subject of a companion application executed and filed of even date herewith.

The blasting-cartridge constructed as described is of a simple and economical kind, may be shipped greatdistanoes with facility and safety, and can be conveniently and offectively applied for use with various kinds of fuses. v

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

1. A blasting cartridge comprising a case, a head having an aperture therethrough a detonating cap having wires extending therefrom to a source of electric energy, and a compressible plug tightly fitting the aperture and embedding the portions of the wire against a compressible plug fitting the aperture be- 16 which it in use rests,substantia1ly as and for tween the wires, so as to embed them and the purpose set forth. i make a'water tight joint, substantiallyas and 2. A blasting cartridge comprising a case of for the purpose set forti w waterproof paper a comparatively heavy card board head having an aperture thereth rough, GfiRsHOJ MOORE PR1 ER?!" 2 detonat-ing cap within such case and con- 'VV ituesses: nected by wires to a source of electric energy, FRED (J.
