' IMPRTO'VEMENT m REVOLVING FIRE-ARMS.

, Specification forming part of Letters Patent No. 129,334, dated July 16, 1872.

SPECIFICATION.

Be it known that I, JOHN GORDON, of San Francisco, San Francisco county, State of To all whom it may concern:

California, have invented Improvements in Fire-Arms; and I do hereby declare the following description and accompanying drawing are sufficient to enable any person skilled [in the artlor science to which it most nearly appertains to make and use my said invention and improvement without further inventionv through with the numerous movements necessary for-ordinarybreech-loading or magazine guns.

In thepresent case my invention is shown as applied to a revolving-chambered gun; and

. it consists in the use of a seriesof levers and springs combined, as hereinafter described, so that. the hammer can be raised and the gun be made ready to fire by pressing the butt of the stock against the shoulder. When the trigger is pulled the hammer falls and discharges a chamber, and at the same instant another spring is released, which again raises the hammer to the position of full-cock, and also operates the mechanism for revolving the cylinder, so that the next chamber is brought into position. By again pressing the butt of the piece against the shoulder the firin g-sprin g is agaiii set, and all thechambers can thusbe discharged without removing the piece from theshoulder.

Referring to the accompanying drawing for a more "complete explanation of my invention-- Figure 1 is a side elevation, partly in section, of the piece, showing the mechanism set ready to be discharged. Fig. 2 is a side elevation, partly in section, showingthe' position of the mechanism after the discharge.

A is the barrel of a gun. B is the revolving-chamber- (J, the small of the stock, and

y D the butt-piece. This butt is hollowed out so as to just slide over the small of the stock, and it has a small movement back and forward for the purpose of operating the mechanism, which is constructed asfollows: Eis

the hammer. F is'the'tumbler, mounted upon the tumbler-shaft G, which carries the hammer at its outer end. H is the trigger, which is connected with the dog or catch I by a bar or link, J, as shown.

top of the tumbler, and thus retains the hammer at full-cock when the spring is set. The main-spring V has its front ,end connected with the rear of the tumbler by a link, L. The rear end of the main-spring is secured to the lever M, so that it ordinarily lies closely against it 5. but when the gun is ready for firing its front end is separated or forced away from the. lever, as shown in Fig. 1. The elasticity of this spring returns it to its place against the lever when the trigger is pulled and the tumbler released, so that the hammer falls. The lever M has its fulcrum at N,gand its rear end is connected with the curved or knee-lever'O by a link, P. The lever O is in turn connected with the operating-bar Q by a link, R. From the front of the bar Q a plate or spring, S, extends forward, and is provided with a catch, t, near its front end. The' bar Q extends back through the small of the stock, and is secured to the butt-piece D by a screw or bolt, U.

The operation will be as follows: The gun being in its ordinary st'atethat is, not set for firing-the parts will stand in the position shown in Fig. 2. The main-spring V will be against the lever M, which will have its front end depressed, as shown, by the spring a, and by this means the tumbler F will be drawn down so that the hammer will stand at fullcock and the catch I will be in position to hold it there when set. The parts being in position, the gun is brought to the shoulder and the butt D pressed firmly against it. This causes the bolt U to force the bar-Q forward, thus carrying the spring S forward, until the catch t is held by the lug c, as

'shown'at Fig. 1. At the same time one arm of the knee-lever 0 is forced forward by the bar Q and the other arm is drawn downward, thus depressing the rear end of the lever M and elevating its forward end. As the tum-- bler is held in place by the catch I this movement of the lever M separates it from the spring V and thus gives it the necessary tension to force the hammer down when released.

PATENT OFFICE.

The spring K holds an catch down so that it falls into a notch in the The trigger being pulled, the hammer falls upon the cap, which is placed upon the nipple,

and thus the gun is discharged. At the same instant'a lug, d, at the lower part-of the tumbler, is carried backward by its rotation so as strike the spring S and release the catch t. This allows the spring a to act upon the lever M and depress the forward end to its first position, at the same time raising the hammer 'to the position of full-cock. The bar Q'and catch 23 are also drawn back b'y'.the action of the lovers, The cylinderB is revolved in the ordinary manner by a pawl, e, which is pinned to one'side of the tumbler, and operates upon a ratchet, f, at the rear of the cylinder. \Vhen the hammer falls the rotation of the .tumbler carries the pawl down one tooth .of

mechanism here shown, as the devices will be modified when applied to the Henry, Spencer,

andother repeating or magazine arms; but

What I do claim, and desire to secure by Letters Patent, is' v 1. The bar Q, and the spring S with its 7 catch it, ineombination with' the movable butt D for setting and holding the mechanism,

substantially as herein described.

-2. In combination with the operating-bar Q and butt-piece D, I claim the levers M and i O and the spring V, the wholeconstruetedto operate substantially as described.

3. The trigger H, connecting-bar J, holdin lever I, and tumbler F, when constructed and operated substantially as herein described. l l 4. The lug d operated by the tumbler F for releasing the spring S, substantially as and v for the purpose above described. I

5. I claim the spring a in combinationlwith the lever M and main-spring V, to return the parts to their position when released, sub-- stantially as and for the purpose above de-- scribed.

6. The combination of devices for automat- Q ically rotating the cylinder, consisting of the 1 levers M andO, springs a and V, tumbler F,

and pawl 0 operating the ratchet f, substan-' tially as and for the purposes above described.

7. In combination with the 'sliding butt D,

I claim the mechanism, substantially as herein described, whereby the main-spring is made operative when. the butt is pressed forward.
