CARTRIDGE.
SPECIFICATION formingpart of Letters ZEatent No. 640,856, dated January, 9, 1900.
Application filed July 3,1899. Serial No. 722,694. (No model.)
To all whom it may concern:
Be it known that I, CHARLES A. BAILEY, a citizen of the United States, residing at Cromwell, in the county of Middlesex and State of Connecticut, have invented an Improvement in Cartridges,of which the following is a specification.
a central opening, of a breech-piecehaving a projection or nipple adapted to extend into the opening of the metal cap and be upset thereon to connect the parts, the inner end of the paper tube being crimped over the breechiece and clamped between said breech-piece and head of the cap.
The invention further consists in providing the nipple of the breechiece with a thin outer wall, in connection with an anvil held in said nipple by upsetting the edges of the breecl'npiece upon the endsof the head of said anvil.
The following specification enters into a detail description of the invention, reference being had to the accompanying drawings, and to letters thereon which designate the different parts, and what it is desired to protect by Letters Patent is more specifically set forth in the appended claims.
In the drawings forming a part of this specification, Figure l is a sectional view of a cartridge constructed in accordance with this invention. Fig. 2 isasimilar view showing the application of the invention in connection with a metal cap having a very thin head.
- Fig. 3 is a detail view of the breech-piece and anvil carried thereby. Fig. is a. sectional view of-a modification of the invention whd're in provision is made for reinforcing the paper tube at the breech of the cartridge.
In carrying out my invention the head A of the metal cap is provided with a central opening a, and in case a very thick head' is employed the outer end of said opening is .the powder. I is therefore provided in connection with the countersunk iuthe usual manner, as shown in Fig. 1, while the metal of a thin-head cap, Fig. 2, is depressed around said opening, for the purpose hereinafter explained.
In connection with the metal cap I employ a breech-piece B, which is adapted to firmly hold the paper tube 0 within the metal cap and also provide an efiective priming device for the cartridge. To this end the said breechpiece is made'up of a disk the central portion of which is stamped or drawn to provide a projecting nipple D, having a thin outer wall d, and the outer edge is turned. to form the flange E. The nipple D is of such size relative to the metal cap that the outer end thereof will fit snugly within the opening in the head of said cap, and the length of said nipple is determined by the thickness of the head at the opening and the thickness of the paper tube, for in making up the cartridge the inner end of the paper tube is .crimped over the edge of the breechpiece, and after both are placed in the metal cap with the nipple projecting through the opening the outer end of said nipple is upset upon the head and serves to clamp the parts together. By countersinking' the outer end of the opening in the head of the metal cap the outer end of the nipple is located below the plane of the outer surface of said head, and as the fulminate is carried by said nipplethe danger of an accidental explosion will be lessened.
The fulmiuate is placed on the inner side of thethin outer wall (1 of the nipple D, and in order to provide for exploding the fulminate an anvil F is located within said nipple and is held firmly with its point f touching the fulminate. This anvil is preferably llshaped, as shown, the cross-bar extending across the disk or breech-piece to bear against the same, while the stem or point f projects into the nipple, the said anvil being held in place lfyupsetting the flange E over the ends of the cross-bar of the same, and for this purpose the ends of said cross-bar are preferably beveled, as shown. this form of anvil will permit a quantity of powder to collect around the point of the same and against the fnlmiuate, so that the full benefit of the dash will be had to ignite A very efiective priming device It will be here noted that particular manner of making up the cartridg a, and in case the headof the metal cap is me de very thin the thickness of the disk B ma; be increased to form a breech-block.
In the modification, Fig. 4, I have shown a construction of cartridge which contemplates the reinforcing of the rear portion of the paper tube H by short sections of paper and metal tubes 41 and 1', respectively, which are let into said tube H and crimped over the breech-block K with the same, as shown. The reinforcing tubes or sections are intended to extend only the distance occupied by the powder in the cartridge, and as they serve to thoroughly reinforce the tube at the breech the collar of the metal cap may be dispensed with and only the head L employed, the said head or washer being provided with an opening 1 to receive the nipple M, e xtending from the breech-block K, and projects sufficiently to form the usual rim. 3
The principal advantages attained by making up a cartridge in the manner herein shown and described are that a-firni and secure connection is bad between the metal cap or head and the paper tube, and the particular manner of making the connection also provides a nipple to receive the fulminate on the inner side of the same and combines an anvil which will permit a quantity of powder to collect in such close proximity to the fulminate as to insure a positive explosion of the cartridge from the flash. The crimped end of the paper tube is firmly clamped between the breechpiece and head of the metal cap, and the parts being thereby securely connected will not be liable to pull apart in .extractingthe cartridge.
' In some cases the paper tube could be reinforced at the breech by inserting only a metal tube instead of metal and paper tubes, as shown in Fig. 4, and of course the said metal tube would be spun over the breechpiece, so as to besecurely held when the parts are connected.
Though I have described the cap as made of metal, it is obvious that other material may be employed, for in some instances I contemplate making said cap of composite fiber or compressed papier-mach. When made of thismaterial, the head and sleeve would necessarily be thicker than when said parts are made of metal. PM.
-Having thus described my invention, what Iclaimas new, ,and desire to secure by Letters -Patent,
1. A cartridge, comprising a metal cap or head having an opening therein, a breechpi'ece provided with a projecting nipple adapted to fit into the aforesaid. opening, and an 6o'anvil secured to, the breech-piece and provided' with a point or stem extending into the nipple; together withihe tube held in place by thecap and breech-piece, substantially as shown and described.

7. In a cartridge, the combination, of the metal cap or head having an opening through the same, a breech-pieceprovided with a nipple adapted to enter the aforesaid openingand connected to the cap or head, a flange on the breech-piece, and an anvil secured to the breech-piece by upsetting the flange over the ends of the anvil; together with the paper tube and reinforcing-sections crimped over the breech-piece and clamped between said breech-piece and cap or head, substantially as shown and for the purpose set forth- In testimony whereof I hereunto affix my signature in the presence of two witnesses.
