IMPROVEMENT IN BREECH-LOADING FIRE-ARMS Specification forming part of Letters Patent No.'37,5 l S, dated January'fiY/Ififil.

TO-aZZ whom it may concern..-

Be it known that I, JARVIS DAVIS, of the city of Buffalo and State. of New York, assignor to PA'rnIoK Snrrn, of the same place, have invented certain new and useful Improvements in Breech-Loading Rifles and I (lo-hereby declare that the following is a full and exact description thereof, reference being had tothc accompanying drawings, nnikingapart of this specification, in which- Figure l is a side elevation of my improved hreech-lmlding ritle. Fig. ']I is a top plan. l ig. III isalongitndinal section. Fig. IV is anlan ot' the s ding abutment as coin-ierted to the guard.

Letters of like name and kind refer to like parts in each of the figures.

The nature of iny invention relates, first,

to the. construction of a spring-hook, in combination with the lock of a breech-loading rifle, so-that when the rifle is tired the hook will Catch under the cartridge and draw the shell or case of the exploded cartridge out of the barrel and throw it oh when the gun is corked, second, in the construction of a slotted sliding abutment so combined and an ranged that when the gun is tired the thin end of the cock-hammer will pass through the slot and strikeand explode the cart-ridge, the

shoulders of the thicker part of the hammer striking against the abutment. and closing the slot.

' A represents the gun-barrel; B, stock; C, guard; I), lock; E, hannner, to which the spring-hook is attached. 1

F represents a hook, which-is hinged or completely jointed to the hammer at the butt-end thereof, as shown at f in Fig. III, the hook end projecting forward of the hammer so as to pass un der the cartridge when the gun is fired.

' G"represents a spring, which is connected to the hammer by means of the screwh, the

free end of the spring lapping onto the buttend of the hook, so as to bear hard against it. The surface of the butt end, against which the spring bears, is made eccentric to the center or joint, so that when the hook is forced down alittle (as it is in drawing out the case of theexploded cartridge) it will throw back the-spring, causing it to press with great forc thereon, and as soon as the cartridgeca-se is liberated from the barrel the spring guard to its position in the stock.

will react and throw the spring back U.- its place, in the hammer with sut'ticient force to throw oft the case of the exploded cartridge. A groove is made in the hammer, in which the hook and spring are placed, and in which they act, as representedin Fig. III. A small recess or chamber-is made in the breech, as shown at '1', in order to allow the hook to pass under the cartridge and hook onto its flange.

J represents the sliding abutment. (The slottherein,isshownnt'j, Fig. l V.) .ltishinged to the guard as shown at C, so that the guard will more it up and down, as desired. When the guard is dropped down to the po, sition ofthc dotted lines U", Fig. III, the abutment will be drawn down to the'position of the dotted lines J. and when the guard is thrown up to its place in the'stock, the abut ment will be carried up to its place in the in Fig. 111; then cock the gun; then put your cartridge into the barrel and draw up the This brings the abutment up to its place in the breech, ready for dircharge. not. discharged directly after loading, tl hammer should be letdown to lmfi'cock, where it may be handled with safety. \Nhen the ritle is tired, the the thin end of the hammer passes through the slot in the abutment, nearly filling it, and strikes and explodes the cartridge. The hook, at the same ti me passingin to the chamber 2',

hooks onto the cartridge, the shoulders of the hammer striking against the abutment. When the gun is discharged, the guard should be immediately lowered, so as to draw the abutment to uncover the bore. Then it should he cocked, and in the actof cocking the hook I as herein described.-

being eonnecteil teiaml operating \ll th the breech, forthe nufposes and substantially as hammer, for the purposes and. substantially set; fm th.
