IMPROVED CARTRIDGE-CASES.

Specification forming part of Letters Patent No. 29,287, dated July 24, 1860;

To all whom it may concern Be it known that I, JOHN PARKER LIND- SAY, of the city, county, and State of New York, have invented a new and useful Improvement in Repeatin g-Oartrid ges for Breech- Loading Fire-Arms, it being a new article of manufacture; and I do hereby declare that the following is a full, clear, and exact de: scription of the construction, character, and operation of the same, reference being had to the accompanying drawings, which make part of this specification, in 'wbich- Figure 1 is a perspective view of the cartridge as it appears externally, with two discharging tubes or passages attached and the rods inserted. Fig. 2 is a section of the same cut longitudinally through the center, showing the internal structure when the case is loaded with two-charges. Figs. 3 and 4 are perspective views of two rods or slides, with the fulminating compound on their inner ends. Fig. 5 is a plan of the rear end of the cartridge.

My improvement consists in attaching to,

or constructing with, the metallic cartridge; case, tubes or passages, to correspond vwith the number of charges in the cartridge-case in such a manner that by means of rods, or otherwise, and an explosive compound, I can ignite the powder of the several charges in their proper succession, by using the hammer or other percussive force at the rear end of the cartridge, so as to preserve the symmetry of the piece or fire-arm, and also avoid the necessity of making any vent-holes through the side of the barrel.

I make the cartridge-case of copper, or any other suitable material, in the cylindrical form substantially as represented at F, Fig. 1, and indicated, in section, in Fig. 2, with as many vent-holes, as O (3, Fig. 2, as there are to be charges of powder and ball.

On the outer surface of this cylindrical case I fix or secure tubes, as A A, equal to the number of charges to be used in the case, of the proper length to extend to and connect with the vent-holes in the cylinder or case, as indicated in section in Fig. 2.

Into these tubes or passages I insert rods or slides, as indicated at B and B, Fig. 2,

with a fulminating compound secured on their inner end, as indicated at D, Figs. 3 and 4. I

These rods or slides may pass through holes or spaces in the continuation of the cap or rear endG of the cylindrical case, and extend out a short distance, as shown in Figs. 1 and 2, for the hammer to strike against, or they may be concealed within said cap or rear end G, and have the hammer perforate the cap G, and thus strike the rod or slide B or B, Fig. 2, to cause the requisite percussion on the fulminating compound, as at D, Figs. 3 and 4, on the inner end, so as to ignitethe powder in the case.

Instead of cylindrlcal tubes, as shown at A and A, Fig. 1, longitudinal segments of such tubes maybe secured to the outer surface of the cylindrical case F, and the rods or slides made to conform in shape, and the hammer applied in either of the ways above described;

or I may make the cartridge-case and the passages for communicating the fire to the powder of one piece of steel, or any other suitable material, and make the chamber for the charges and the passages by drilling, or in any other convenient way, and insert nippies at the rear ends of the passages, and use caps in the ordinary way-dispensing with 1 of course, the breech-end of the barrel of the piece must be fitted to receive thecartridgecase, with its appendages.

I' am aware that repeating-cartridges have been used which'required separate locks, one for each charge, fitted along the barrel of the piece, and separate touch-holes or vents drilled through the side of the barrel, as described in Newtons Journal, first series, volume 13, pages 72 to 73; but they were soon abandoned as being too clumsy and inconwith the discharging tubes or passage s, when venient. I therefore do not claim any such the whole is combined, arranged, and fitted contrivance as my invention; 'but for use, substantially as herein described.

What I claim as my invention'and desire T to secure by Letters Patent, as a new article JOHN PARKER L 1ND of manufacture, is- Witnesses The cartridge-case made with its chamber E. CRAIG, for receiving several charges, in combination R. FITZGERALD.
