UNITED STATES PATENT. OFFICE. CHARLES A. YOUNG, or ENON, orno.

FIREARM 1' lov'ving to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to make im* provements inasingle-barreled two-shot gun; and the invention consists in the provision of improved safety devices to hold the barrel locked against the standing breech until the devices are manually operated to permit the release of the barrel from the standing breech. The'invention also consists in other constructions or combinations, as hereinafter described and claimed.

purpose to be hereinafter explained. Ar-

ranged in the breech-block frame forward of the carrier-chamber d is" a barrel-latch a consisting of a cylindric slug having a nose 67/ 31] its upper end, said nose being square at its rear side and beveled at its forward side,

the square side of the nose adapted to engage the forward recess a when the barrel is closed and the rear recess a when the barrel is opened. "The beveled forward sidev of the nose of? permits the barrel to be drawn rearward over the said" nose toward the standing breech. The barrel-latch 03 is normally held up toward the barrel by a spring a, con-' tained in said latch and seated on the bottom plate of the breech-frame. The said barrel latch is also made of such length that when it engages the forward recess a) there is a small v space between its lower end and the bottom plate of the breech-frame, and because the recess a is shallower than the recess a this space is partially or completely closed when the gun is opened to said recess a The purpose of the construction just described is to secure and lock the barrel in closed position until the gun is fired to pro vide a limiting-stop for the barrel in its ex-. treme open position and at'the-same time permit the ready closing of the barrel from that position by simply pulling the barrel toward 1 the breech-frame.

The breech-bolt h hasa laterally-projecting cross-pin h operated by the cocking-lever it",

(see Fig. 4;) but in the present instance, as distinguished from the construction shown in my former patent hereinreferred to, the cocking-lever is at the opposite side of the firing.- pin and the cross-pin it projects from the firing-pin in both directions. Piv'oted at h 9 to the standard or post of the firing-pin'frame is a lever h havingits upper end lying in front of the cross-pin if and its lower end made with a notch k and a finger-piece h, the latter projecting through a slot. in'the bot-; tom plate of the breech-frame. Engaging the notch k of the lever h is. the rear' end ofv a rod 71 that extends forward to the barrel-J latch, where it is provided with 'athickenedend it, adapted when projected under said barrel-latch to prevent the depression of said latch, and therefore the opening of the gun;

I The lower end of the lever? is pressed at its rear by a spring h 7, tending to throw the rodit forward, and therefore lock the barrel in closed position; but the rod fi canebe pulled rearward againstsaid spring ll? by pulling rearward with a finger of the hand on the finger-piece if. When the trigger is pulled, as; in firing the gun, the cross-piece It being pressed with a spring of greater power than that of the spring [L27 the upper end of the lever k is pressedforward, and therefore with draws the end 72, of the rod if from under the barrel-latch a and holds the rod h until the gun is recocked and the pin h retracted.

Slidingly mounted in the standard of the breech-frame is a small notched pin it. This pin is furnished with a weak spring it. tending to push said pin forward; but a cross-pin it in the pin it, to abutagainst the rear side of the standard, limits the forward movement thereof. Said pin it also projects sufficiently to be acted on by the upper end of the lever it when the latter is moved rearward by the spring b and the pressure of the cross-pin h is withdrawn in recocking. Fig. 1 illustrates the cooked position of the gun. In this position the sear k which releases the firingpin, as usual, is free to be moved to fire the gun by reason of the position of the notched trigger-locking pin h. Fig. 6 illustrates the position of the pin hi after the gun is fired, and in this position said pin prevents the operation of the sear h", and therefore the pulling of the trigger, until the gun is closed and recocked.

The carrier 6 is lifted out of its chamber at under the breech end of the barrel by a spring 6 and it is depressed into said chamber by the breech end of the barrel in closing and loading substantially as in'my former patent hereinbefore referred to. Sometimes, however, it may be desirable not to use the weapon as a repeating or two-shot gun, and in such event the carrier should be latched down in its chamber d. To effect this, I now provide the under side of the carrier-supporting lever 6' with a notch e to be engaged by a catch e sliding in a slot in the bottom plate of the breech-block frame and operative independently of the trigger, said catch being provided with a finger-piece on the exterior of the bottom plate and a small spring to make sufiicient friction to hold or assist in holding the catch in the position to which it is moved, as clearly indicated in Fig. 5.

The cocking-rod for operating the cookinglever it is composed of two parts-one, it, attached to the cocking-lever, substantially as shown in my former patent herein referred to, and the other, it, slidingly attached to the sliding grip f. The parts of the cockingrod automatically hook or couple together in fixed but detachable relation to each other,

so that in assembling the gun it shall not be necessary to manipulate the parts of the cocking-rod to effect their coupling. In Fig. 4 the. parts it and h are each shown to be made with a notch and a beveled end, but placed in reversed position and in line with each other,

sothat when the two ends come together in closing the gun in assembling they will, by the contact ofthebeveled ends, spring apart and hook together, as indicated in Fig. 3. After the parts of the cocking-rod are hooked together, as shown in Fig. 3, the abutting shoulders behind the notches and the hook ends prevent their separation longitudinally with respect to each other. In taking down the gun the parts of the cocking-rod are separated by springing the coupling ends asunder with the fingers of-the hand. The movement of the part it in the grip f is limited by the contact of the shoulder If with the end of the grip.

The grip f slides, as before indicated, with a limited play on the barrel, and it is provided at its rear end with a rigid arm f, carrying at its rear end an anti friction-roller. Pivoted at a between the sides of the forward end of the breech-block frame is a lever a, the rear end of which engages the barrel latch a and the forward end" of which is shaped and located to be wiped by the antifrictiomroller on the rear end of the arm f, so as to depress said barrel-latch out of the forward recess a" in the under side of the barrel preparatory to moving the barrel from the standing breech. This, however, it will be remembered, can only be done after the end if has been with drawn from under the .latch a as before stated. Thus it will be observed that the danger of firing the cartridge or shell after the gun is partially opened or before the gun is completely closed is avoided. When the gunis used asa repeating or twoshot gun, a shell or cartridge is first put into the carrier and the carrier depressed into its chamber to permit the insertion of a second shell or cartridge into the breech of the barre]. The barrel is then closed on the standing breech, as indicated in Fig. 1,. when the gun is ready to be fired. The discharged shell is then withdrawn and e ected upon the opening of the barrel and the loaded shell or cartridge brought by the carrier into position to load, substantially as in my former patent hereinbefore referred to.

When the weapon is to be used as a singleshotgun, the carrier is locked down in its chamber and the shells loaded into the breech of the barrel, fired, and ejected as though therewere no carrier.

In my claims where I use the term car tridge I mean either a shot-cartridge or a' bullet-cartridge, because the improvements described are useful either in a shotgun or a rifle.

What I claim, and desire to secure by Letters Patent, is-

1. In afirearm, the combination of a breechframe, a firing-pin and a cocking-lever therefor, a sliding barrel and asliding grip on the barrel, a cocking-rod connecting the cookinglever and the grip, a latch for latching the barrel in its closed position, means operative by the grip for disengaging the latch upon the opening of the gun, and a spring-actuated device to lock the barrel-latch when the firingpin is cooked. 1

2. In afirearm, the combination of abreechframe, a firing-pin and cocking-lever therefor, a sliding barrel, and a sliding grip on the barrel, a cocking-rod connecting the cockinglever and grip, a barrel latch for latching the barrel in its closed position, means operative by the grip for disengaging the latch from the barrel-upon the opening of the gun, a springactuated device to automatically lock the barrel-latch when the firing-pin is cocked, and means whereby said spring-actuated device may be operated manually to unlock the barrellatch.

3. Inafirearm, the combination of a breechframe, a firing mechanism including a firingpin and a scar, a cocking-lever for the firingpin, a sliding barrel, a sliding grip, a cocking--v rod connecting the grip and the cocking-lever, a barrel-latch for latching the barrel in its closed position, a spring-actuated device for locking said latch when the barrel is closed, and means for lockingthe sear when the barrellatch is unlocked.

4. Ina firearm, the combination of a breechframe, a firing mechanism including a sear, a

sliding barrel, a barrel latch for latching the barrel in its closed position, a device for locking the scar, and means for simultaneously locking the barrel-latch and releasing the sear.
