U TED STATES PATENT OFFICE,

FREDERICK BEESLEY, OF LONDON, ENGLAND.

LOCK FOR BREAKDOWN GUNS.

SPECIFICATION forming part of Letters Patent No. 320,040, dated June 16, 1885.

Application filed January 24, 1885. (No model.) Patented in England January 2, 1884, No. 425, and in Belgium December l, 1854. No. 67,064.

To all whom it may concern:

Be it known that I, FREDERICK BEESLEY, a subject of the Queen of Great Britain, resid ing at London, England, have invented new and useful Improvements in or Applicable to Breakdown Hammerless Guns, of which the following is a specification.

The improvements constituting this invention are applicable to breakdown hammerless guns; and they consist of improved means or arrangements of parts for automatically effecting the cooking of the tumblers when opening the gun for inserting the cartridges, and for similarly effecting the compression of the springs when closing the gun, thus rendering them effective for discharging the cartridges when the tumblers are released from the sears in the usual manner.

Figures 1 to 4 of the accompanying drawings illustrate the application of the invention to a body-action gun. Figs. 1 to 3 are longitudinal sections through the line a b, Fig. at, looking in the direction of the arrow 0,- and Fig. 4 is a cross-section through the line d e, looking in the direction of the arrow f.

The improved means hereinbefore referred to consist of fiat spring-levers 1, which are pivoted, as at 2, at the front end of the action, near the knuckle-joint 3, and have their forward ends, 4, projecting beyond the knucklejoint and through slots 5, cut in the fore part, 6, and lying under the barrels 7 of the gun, or projecting into similar slots out only in the iron of the fore part, and lying under the upper part of the slotted iron, and have their rear ends, 8, each extending into engagement "with a slot, 10, in the lower forward part of one of the tumblers 11, and with which slots the rear ends of the springs always engage.

Over the spring end 8 of each of such levers 1 there is pivoted, as at 12, in the action a tumbling lever, 13, and these tumbling le vers 13 are actuated by the under part of the barrels, or by a cross-bar, 14., carried by one, and preferably the forward one, 15, of the steel lumps of the barrels, in such a manner as to cause a regular compression of the spring while the gun is being closed after the cartridges have been inserted. The spring-levers 1 and tumblers 11 are arranged in two slots,

16, out along the bed of the action, (see Fig. 4,) one for each lock mechanism.

I would remark that the improved means herein described may partly or wholly be mounted on side or look plates, either of the bar-action pattern or of a back-action pattern, or part of the n1echanismsuch, for example, as the tumblers and sears and sear-springsmay be mounted on the trigger-plate; but in all modifications I prefer that the spring-levers, with their respective compressing-tumblers, should be supported by the action.

The action of the mechanism herein described is as follows: As the barrels are opened the under part thereof, or the adjacent part of the fore part, depresses the forward'projecting ends 4 of the pivoted spring-levers 1 in the direction of the arrow g, causing the spring ends 8, engaged with the slots 10 in the tumblers 11, to be uplifted in the direction of the arrow h, thus causing the tumblers to be lifted to full-cock, where they are retained by the sears 17. (See Fig. 1.) On closing the gun the crossbar 14 bears in the direction of the arrow i, and causes the pivoted tumblers 13 to compress the spring ends 8 in the direc tion of the arrow j against the resistance offered by the tumblers still held by their respective sears, (see Fig. 2,) and to such an extent as suffices to discharge the gun when the tumblers are released from the scars by the usual action of the triggers. Then the parts are caused to assume the positions shown in Fig. 3, from, which they are all again removed to the positions shown in Fig. 1 by the mere act of opening the gun.

It will thus be seen that in accordance with the present improvements I dispense with double or V or spiral springs, and with all modification of the Stanton mainsprings, and also with all such cams, levers, thrust-rods, and other like appliances as have been previously necessary when used in effecting the object of the present improvements in various combinations with the Stanton mainspring, and in lieu thereof substitute in each lock mechanism a much simplified arrangement of parts, consisting of a single flat spring-lever, which, as hereinbefore described, acts in itself both as a lifting or tu1nbler-cocking lever, and

also as a spring foractuating the tumblerfor discharging the gun.

Having now particularly described and ascertained the nature cf my said invention, and in what manner the same is to be operated, what I claim is- The hereinbefore-described improvement in or applicable to breakdown hanimerless guns, consisting in the'combination, with the turnbler and sear, 0f the lever, one end, 8, of which is a spring which is connected with the turnbler, and said lever serving the double purpose I I
