BREECH-LOADING FIRE-ARM.

SPECIFICATON forming part of Letters Patent No. 297,784, dated April 29, 1884.

Application tiled December 19, 1883.

To @ZZ whom it may concern.-

Be it known that I, Pr-riLIr Til-reims Gonsir., of Eton, in the couirty ofBackingham, England, have invented certain new and useful Improvements in Breech-Loading Fire-Arms,

of which the following is a specication.

This invention relates to that class of breechloading fire-arms in which the sliding breechbloclr is actuated by a lever, the objects being 1c to simplify the construction oi' such arms and to increase their efficiency. The breech-block, which covers the breech end of the barrel, slides in guides formed for it by t-he sides or cheeks of the breech-case, and it is held in r 5 place against theback-pressure of the ignited charge by the metal iacings at the rear end of the breech-case. ln order to raise and lower this breech-block, a lever external of the breech-case is made to connect with the block, 2o and thus serve, as the lever isrocked, to draw down the block in its guides, so as to expose the breech end ot' the barrel, or to force up the block into the closed position. The fulcrumpin of the breech-lever serves to carry the 2 5 hammer, and also the cartridge extractor, which latter is so arranged that whenthrust forward by the act oi' inserting a cartridge it will effect the rocking of the breech-lever, and thereby enable the mainspring to complete the 3o closing of the gun.

In the accompanying drawings I have shown my improved fire-arm in three positions and several parts ofthe action in detached views.

Figure -1 is a longitudinal section of the gun 3 5 in the iixed position. Fig. 2 is alongitudinal section of the gun open. Fig. 3 represents the gun loaded and in the position for tiring. Fig. 4 is a cross-section of the gun on the line x w of Fig. l. Figs. 5 represent plan, side, and end 4o views of the breech-case. Figs. 6 represent side and end views of the trigger-plate forming the bottom ofthe breech-case. Figs. 7 are side and back views of the extractor. Fig S are side and back views of the inner portion 4 5 oi' the compound breech-lever. Figs. 9 are side and front views of the hammer; and Figs. 10 are plan, side, back, and front views of the breech-block.

wrought-metal body or breech-case B, into the front of which the barrel O is screwed.

D is the breech-block, which closes the breech end of the barrel. This block slides between the sides of the breech-case B, and is held in place against the back-pressure of the ignited charge by the vertical metal facings b.

E is a side lever from which the motion is derived for raising and lowering the breechblock D, and E is a virtual extension of this lever, connecting the same with the breechblock D. This piece E/ is formed with a sleeve, c, which projects outward beyond the breechcase, and is squared to receive the detachable hand-lever E, the breech-case being slotted to provide for the insertion ot' the sleeve. F is thev hammer, G the trigger', and H the cartridge-extractor. The three pieces FJ, F, and H all work on a common fulcrum, I, which is carried by the trigger-plate K, which forms the closed bottom of the breech-case B.

L is the mainspring for actuating the hammer and for holding the breech-lever in its opening and in its closing positions, its stand 7 side being utilized i'or retaining the block in its set positions.

The piece E is bell-cranked,`and its sleeveextension c receives the Fulcrum-pin I, on which the hannner and extractor are loosely mounted. The angle c is slightly rounded, to allow of its rocking or moving freely over the stand side of the spring L, to present the straight portion of thc arms oi' the bell-crank alternatcly to the spring, which, by its pressure thereon, maintains the lever in its set positions. The extremity e2 of the crank-lever or piece E underlies the breech-block D, and a bracket projection from the underside of this block underlies the end c2. As, therefore, the breech-lever is rocked, its end cl will raise or lower the breech-block, and thereby close or open the gun. The tail of the crank-lever has a lateral extension, e, which underlies the tumbler of the hammer, and extends beyond it into the range of motion of the extractor. This is for the double purpose of actuating the extractor to throw out the exploded cartridge, and to receive from the extractor a movement for starting the breech-block from its depressed condition, and for presenting to the so-called stand side of the spring L an inclined surface that will enable that spring, by its pressure thereon, to complete the upward movement of the breech-lever, and consequently of the breech-block. The mainspring L, it will be thus seen, is used to perform a double duty. A

It is connected, as usual, by alink to the tumbler; and to enable what is known as the "'stand7 side to act as a spring, the connection is made with the trigger-plate at the bend of the spring.

The trigger-plate K is formed with vertically-extending sides, which serve to receive near the front end of the platea hinge-pin, 7c, which connects it with the breech-case B. These sides also carry the fulerum-pin I and the parts connected therewith; and to secure the plate in place, a transverse screw-pin, k, is used, the same being passed through the breech-case and the sides of the trigger-plate. The trigger is pivoted to the plate by means of a transverse pin, as usual. This plate and also the breech-case terminate rearward in tangs, which serve to embrace the stock A, and are secured thereto by screws.

The breech-block D is hollowed out and pierced to allow the hammer striking through it to explode the cartridge. y

Supposing, now, the gun to have been fixed, as indicated in Fig. l, and that it is desired to prepare it for a second discharge, the lever E is depressed, as in Fig. 2, in order to bring down the breech-block and expose the head of the cartridge. In doing this the hammer is iirst tipped back clear of the breechblock, its tumbler being pressed upon by the lateral extension e3 of the cranked lever E, and as the downward movement of the lever is continued the breech-block begins to de-' scend. Meanwhile the cooking of the hammer proceeds, and it is completed simultaneously with the descent of the breech-block to its lowest position. So soon as the head of the cartridge is completely exposed to view, the part ci of the crank-lever will strike against the front of the extractor H and cause it to throw out the empty cartridge-case. On applying a fresh cartridge to the gun, the extractor will be caught by the iianged head of the cartridge, and as the cartridge is thrust home the extractor will be forced against the extension e of the rock-lever, thereby thrusting it back into its place and bringing the crank-lever into a position to lift the breechblock. This rockingmotion of the lever will cause the stand side of the spring L to yield to the pressure of the elbow of the lever, and the elbow having passed, the spring will resume its position, pressing on the-lever and causing it to effect the lifting of the breechblock, at which time the position of the parts will be as represented at Fig. 3. By this automatic action of closing the gun, one movement of the hand of the operator is saved-a matter of considerable importance when rapid iiring is required.
