IMPROVEMENT IN METALLIC CARTRIDGES.

The Schedu1e referred to in these Iietters Patentand making part of the same,

To all whom it may concern Be it known that I, RoLmnWnIrn, of Lowell, in the county of Middlcsex and in the State of Massachusetts, have invented certain newand useful Improvements in Cartridge; and do hereby declare that the following is a full, clear, and exact description therr'f, reference being had to the accompanying drawmg and to the letters of reference marked there on, making a part of this specification;

The object of my invention is to produce a cheap yet substantial cartridge, the case of which shall partor divideavhen.leavingtheglm and It consists in the construction and arrangement of the various parts forming said cartridge, as will hereinafter be fully set forth.

In order to shableothersmkilled in the art to.

which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1- is a longitudinal vertical section of my cartridge; and

Figures 2, 3, and 4 show various modifications of the same.

I A represents the cap, within which is the space a, for the fulminating powder, with the vent i from said space.

"Around the vent i, forming a plate or part of the cap, is the anvil b.

- cl is the opening in the head or butt B, in which The walls or sides of this cap-chamber are vertical, as shown at :v, figs. 1, 2, 3,,and 4. This cap may be made by any suitable means of one or more plates, and inserted into the aperture of the head, where it is to be held by any means desired, so as to prevent it from being forced into the cartridge by the blow of the hammer. Its

upper or outer surface may or may not he concave in the center, and, if concaved, making the metal at this point much thinner. At or near the center is the only place where a blow will ignite the fulminate. Hence, it follows that even if'thecap should be flush with the outer surlace of the head, no ordinary glow n y by a blow of a pointed hammer orother similar instrument directly in or near the center of the cap will the fulminate he exploded.

'Within the head B maybe placed a plate, I), to form the cartridge anvil, in which case the anvil b of the cap may or may not be dispensed with, as desired.

' 111 some cases I may form my cap without the vent i, in which case a portion of the plate or anvil should be made so thin or weak that the explosive force of the fnlminating powder will burst, through and drive the the intothe charge or cartridge.- 1 I The head or butt B is formed with a thick portion or circular flange, x, around the opening d, in which the cap is inserted.

A short distance from, outside of, and around this flange is another circular flange or lip, y, which forms a reinforce or hearing for the paper tube It.

This tube is placed around and against the lip y, and is confined by means of a short metallic tube, 0, which is flanged at its rear edge, as shown, and the flange e of the'head is then bent over the flange of this metallic tube, thus holding the two tubes 0 and 7c in place.

The flange or lip y andthe metallic tube 0 extend equal distance forward, and the paper tube 7:7 is thus held firmly between two straight metallic surfaces.

By using the paper tube It the metallic tube 0 need :tinlybelong enough. so as .to hold thepaperjuhe firmly, thereby lessening the expense. There is also another object in using said paper tube, which will be presently described.

I) represents the main tube or shell of the cartridge,

'made of paper nud'cloth or other suitable material,

same, as shown at 71 The tubes k and, D are connected together by means of paper, m, pasted or otherwise fastened around the same. If the tube 7; was made of metal, it would be difiicnlt to paste the paper tube at on it but being of paper, this is readily done. This outside covering in being merely a single thickness of paper, allows the cartridge to divide or separate at h, and the power of the charge will drive or carry thefront portion, with the ball or'shot, out of the gun.

The shell I) is, as above mentioned, adapted to form the patching-of the ball or shot.-

The ball E is grooved and placed within the patching. "A string is then'wound firmly in the grooves,

with some soft or greasy substance. .This string r' mains in said grooves until-the cartridge is fired, and while the ball is passing through the atmosphere the string will unwind, and the ball will leave the tube or shell soon after it leaves the gun.

1-Iaving thnsfully described my invention,

What I claim as new," and desire to secure by Letters Pate11't,;is-j-. p 1. The cap-chamber d,-with parallel vertical walls, as, extending allthe way through the base, substantially as set forth. v

2. The cap A, having a concavity in itsputer snr-. face, and-provided with a fuhninateueceptacle, a, and anvil b, with or without the vent t, substantially as set forth.

4. The combination of .the cap A, constructed as described, and the plate or anvil b, s-ubstantially'as and for the purposes herein setjbrth.

5. The head or butt B, constructed as described, with a flange, e, and lip y, substantially as and for the purposes herein set forth.

6. The combination of the head B, metal tube 0, and paper tube It, all constructed and arranged substantially as and for the purposes herein set forth.

7. -The combination of the head B, with its tubes 0 and f, and the tubeor shell D, constructed as described, and connected together by means of the outside covering m, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 21st day of September, 1870.
