BREECH-LOADING FIRE-ARM.

SPECIFICATION forming part of Letters Patent No. 250,189, dated November 29, 1881. Application filed March 24, 1881. (No model.) Patented in England January 3, 1880, and in Belgiuniscptemher 20, 1880.

To all whom tt may concern:

Be it known that I, FREDERICK BEEsLEY, of Queen Street, Edgware Road, in the county of Middlesex, England, have invented certain new and useful Improvements in the Locks of Break-Down Guns, (for which I have obtained Letters Patent of the Government of Great Britain, No. 31, dated January 3, 1880, and a Brevet dInvention of the Government of Bel- IO gium, No. 52,603, dated September 20,1880,)

of which the following is a specification.

The object of this invention is to improve the action of self-cocking break-down guns, and also to render it impossible for the ham- 1 5 mers to drop while the gun is open (even though they should be released from the sears) by reason of the mainsprin gs being rendered powerless so long as the gun is open.

In carrying out my invention I use a main- 2o spring constructed on the principle of that described in the specification of an English patent granted to John Stanton, and bearing date February 9, 1867, No. 367, the stand side of which spring is elongated to serve.

2 5 as a cocking-spring. The stand side of this spring, in the case of forward-action locks, I cause to bear onthe tail end of the tumbler, and while thus bearing upon it the other end of the mainspring, which is connected, as usual, to

the hammer, is powerless to act, the extensionpiece pressing up against the tail end of the tumbler. This state of thin gs occurs when the gun is open or the barrels are dropped. So soon, however, as the barrels are raised into position and the gun is closed the'stand side of the mainsprings will be depressed clear of thetailof their respective hammers, the springs will be cramped, and they will thereby regain their power for throwing down the hammers.

In carrying out my invention 1 have found that the principle of action admits of embodiment in various forms, both as respects the cramping of the mainsprings and the cocking of the hammers, according to whether the in 5 vention is applied to a forward or a back action lock.

In the accompanying drawings, Figures 1 and 2 show in partial side elevation a breakdown double-barreled gun fitted yvith for- 0 indicates the lock-plate, one only being shown in the drawings.

D is the mainspring, pivoted to the lockplate 0 at d, and connected at its lower end permanently, by a link or swivel, c, to the hammer E, which hammer is pivoted, as usual, to the lock-plate.

F is the bridle-piece, which carries the inner end of the pivot-pin of the hammer, and also the inner end of the pivot-pin of the sear Gr.

Above the extremity of the so-called stand side of the mainspring D, and in contact therewith, is a tumbling-lever, H, which is recessed into and pivoted to the lock-plate G. This tumbling-lever receives a rocking motion from the thrust of a horizontal sliding rod, I, 7 5 which tits loosely in a hole drilled longitudinally through the breech-block, (see Fig. 3,) and terminates in a recess, K, in the breechblock, made to receive a cam mounted loosely on thehinge-pin of the gun. This cam (one for each lock) is shown at L, Figs. 1 and 2. As the gun is closed by the raising of the barrels into line, the cam L will be rocked by the pressure of the barrels upon a fiat portion of their periphery. The increased radius of the 8 5 cams, being thus brought up into contact with the forward ends of their respective rods 1, will thrust back the rods and cause them to rock the tumbling-levers 11, thereby depressing and holding down the stand side of the 0 mainsprin gs D. By this forcible depression of the stand side of the mainspring the other end of' the mainspring, or that which is linked to the hammer, will be free to answer to the action of the trigger, the barrels being at this 5 time securely locked in place. After the firing of the gun the hammers will remain down; but so soon as the gun is unlocked and the barrels are dropped the sliding rods I, being released from the pressure of the cams L on the hingepin, will Withdraw their pressure from the tumbling-levers H- and allow the stand ends of the springs to rise into contact with the tail ends of the tumblers, when the rebound of the hammers will take place, the parts taking the position shown in Fig. 2.

Having now set forth the nature of my invention, I wish it to be understood that I claim- In a self-cocking break-down gun, a cam, L, in the breech-block, actuating through a sliding rod, I, the tumbler-lever H, which bears upon the stand side of the mainspring, for the purpose of' cramping the mainspring by the'act of closing the gun, (whereby the spring is made eft'ectivefor firingthe gun,) such spring, when uncramped, on the opening of the gun, being free to cock the hammer, substantially as herein described.
