IMPROVEMENT IN BREECH-LOADING FIRE-ARMS.

tober, A. D. 18615 and my improvements consist of certain novel mechanism, fully described hereinafter, for effectually Withdrawingthe case of the metallic cartridge from -the bore of the barrel.

In order to enable others skilled in the art to make and use my invention, -I will now proceed to describe its construction and operation.

, On reference to the accompanying drawings, which form a part of this specification, Figures 1 and 2 are longitudinal sections of sufficient of a breech-loading re-arm to illustrate my improvements, and Fig. 3 is a transverse section on the line l 2, Fig. 2. y

Similar letters refer to similar parts throughout the several views. A represents the barrel of my improved rearm; B, the stock; C, the hammer, and D the breech-piece, hinged to the barrel at Fig. 3. A hoop or ferrule, a, is secured to, or forms a Y part ofthe rear of the barrel, and the hinged breech-piece is so adapted to this hoop that when depressed' the breech-piece may be said to form a part of the' barrel. A cam-shaped projection, b, with a beveled edge is secured to or forms a part of the breech-piece, and is` so situated inA respect to the metallic case of the cartridge X that on elevating and throw- -ing back the breechpiece the beveled edge of the projection shall bear against the flange of the cartridge and withdraw the same to a limited extent from the bore o'f the barrel.

The above-mentioned parts are too similar to those described in my aforesaid patent of October 8, 1861, to needfurthcr explanation.

A spring, E, situated in an opening formed in the stock at the rear of the barrel, is secured to a plate, F, attached to the under side of the stock, the spring being of such a length that it will bear at its upper end against the inside of the flange of the metallic cartridge X, as shown in'Fig; l. In the 'rear of the breechpiece isa circular opening forthe reception of the nipple G, which is so situated in respect to the hammer as to receive the blow from the same, and so situated in respect to the flange of the cartridge that the end of the nipple which is reduced in diameter, can strike the said flange and-ignite the detonatc contained therein. A spiral spring surrounding the ni pple and contained in the opening in the breechpiece serves to move the nipple back when the hammer is not in contact with it, and a screwpin, e, penetrating an oblong slot in the nipple, prevents the escape of the latter from the breech-piece. Prior to the insertion of the cartridge, theA breech-piece is elevated and thrown back, Vso as to expose the bore of the barrel in which the end ofthe cartridge is introdueed. On'pushing it forward to its proper position, the flange is brought into contact with the upperend of the spring E, which yields and' permits the cartridge to be pushed to nearly its proper position, the last push-being imparted to the cartridge by that portion of thebreccli-picce which is so beveled that when depressed it bears against the end of the case ofthe cartridge. The several'parts are now inthe position-.illustrated in Fig. l, and the fire-'arm is in a .condition for its load to be discharged, this being'accomplished by the ham-- mer through the intervention of the nipple in a manner which needs nodescription. After the discharge of the cartridge, the breech-piece is elevated and thrown back, so that the case of the spent cartridge maybe discharged from the bore of the barrel, and a new cartridge inserted therein.

During .the elevation of the breech-piece, the beveled projection b, bearing against the liange of the case, withdraws` the latter from the bore to a very limited extent. At the same time the edge ofthe projection b bears against the side of the case andretains the same, thereby preventingl the springfrom forcing the case fromthe bore until the latter is thoroughly exposed and the breech-piece presents no impediment to the withdrawal of the spent eartridge. The full force of the spring is thus reserved until the breech-piece is, thrown back and its projection b is free fromfcontact with the cartridge-ease, when the spring acting on' the same will suddenly force it from the bore and 'discharge it clear of the irem'm.

I claim as my invention and desire to secure by Lette1sIatent- Thebeveledprojectionbon the bre-empiece, B. F. JOSLYN.

in combination with the spring E, when both are arranged for joint action on the case of Witnesses:

the cartridge, substantially as set forth, for the N. B. PALMER, 2d, purpose described. O. B. GRANT.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
