BREECH-LOADING GUN.

SPECIFICATION forming part of Letters Patent No. 444,574, dated January 13, 1891.

Application filed J'anuaryZ, 1890. Serial No. 335,721. (No model.) Patented in France October 27, 1887, No. 186,977; :in Belgium April 24,1888,No.81,549; inEngland May 9,1888, No.6,936, and in Italy July 30, 1889,1Tgo. 25,915.

To all whom it may concern:

Be it known that we, PTRUS BLACHON and ETIENNE MIMARD, citizens of the French Republic, both residing at St. Etienne, in the Department of Loire, France, have invented certain new and useful Improvements in Hammerless Fire-Arms, (Letters Patent for the said invention having been granted to us in France October 27, 1887, No. 186,977; in Belgium April 24:, 1888, No. 81,549; in England May 9, 1888, No. 6,936, and in Italy July 30, 1889, No. 25,915,) of which the following is a specification.

v Our invention relates to improvements in that class of so-called hammerless fire-arms 7 which are generally used for sporting purposes; and the objects of our invention are, first, to avoid all projecting movable parts, which frequently cause accidents in handling the fire-arm, and, second, to provide means for facilitating the manipulation of the arm and for indicating automatically if either of the barrels is charged with a cartridge. IVe obtain these objects by the mechanisms and arrangements illustrated in the accompanying drawings, in Which- Figure 1 is the rear part of the arm, showing the lock in a longitudinal section and in the position wherein the barrels are locked and the firing-pin at rest. Fig. 2 is the same sectional view, showing the barrels elevated and the firing-pin cocked. Fig. 3 is atop view of the rear part of the nre-arm with the indicating device, the barrels being partly in sec- Fig. 4 is the butt-end, partly in section, showing a device for automatically stretching the gun-belt close to the stock as soon as the arm is removed from the shoulder. Figs to 11 illustrate the lock parts in details.

The motions for charging the arm are made by means of the pivoted lever c, which laps over the` trigger-guard p and locks the barrels in firing position by engagement of its notch o2 with a piu fu', passing through a sliding piece o. This sliding piece o is guided within a cavity o3, Fig. 5, of the lock-frame, and receives in a slot o5 the lugs o6, projecting beneath the barrels, which it allows to elevate or depress when the sliding piece c is retracted by means of the lever c, Fig. 2.

For locking the barrels the lever c needs to be depressed, whereby the sliding piece u is pushed forward, so that suitable projections o4 o7 of the latter will enter the recesses v9 and o8, Fig. 2, of the lugs. Vhile the sliding piece 'u is retracted bythe lever c, it simultaneously acts by means of its lateral projections t' t" upon corresponding lugs s of the traverses E, situated at both sides of the sliding piece c and carrying at their upper end the firing-pin e for each barrel. At their lower end each of these traverses is provided with a rod c', extending within a prolongation of the frame beneath the barrels, and being adapted to receive between the head u and the inwardlyprojecting annular part of the boring of the frame a helical driving-spring d, which tends to draw the traverse with the firing-pin into the firing position, Fig. 1. As soon as the lever c is elevated into the position Fig. 2, and thereby the sliding piece o withdrawn against the tension of the driving-spring d, the .firingpins of both barrels are cocked by the aid of the short arm g of each trigger g, which engages under the action of a spring f over the projection s of the traverse E, Fig. 2. In this position of the firing-pins c the lever c and the sliding piece o may be moved independently from the action of the spring d and the barrels elevated or depressed, as may be required.

The triggers g, forming with the prolongations g double-armed levers, are pivoted to the frame separate from another in the usual manner. The trigger-guard p is provided with suitable cavities 202133, for the reception of the triggers in such a manner that the latter may entirely recede within the cavities of the trigger-guard unless the firing-pins have been cocked before. At the rear end the trigger-guard is also suitably formed to receive the rear branch of the lever c, so that only the handle c3 will project beyond the triggerguard when the barrels are depressed.

In order to indicate whether the barrels are charged, the pins tt are passed through that part of the frame which forms the breech of the barrels, and they are adapted to recedeV charged with a cartridge R the rear end of the latter will press said pins t t', respectively, backward, so that it will appear at the outside of the frame next to the stock of the arm, as shown by the pin t', Fig. 3.

The last part of our invention relates to a device for automatically stretching the gunbelt, so that the latter may be drawn close to the stock as soon as the arm is taken from the shoulder; and it consists of a spiral spring 3, wound upon a disk 2 Within the butt of the arm and journaled between suitable bars l. The free end of said spring 3 is passed through al guide-plate i and connected to thev gun-belt, so that the latter will be stretched straight under the action of the spring; but as soon as the arm is hung over the shoulder by means of the gun-belt the spring 3 is accordingly unwound.

From the foregoing explanation it will be easily understood that provisions have been taken to the utmost possible degree and that the subject-matter of our invention is based upon the idea to obviate any movable part to protrude from the arm in order to coinbine easy operation with a 'high degree of safety against accidents in handling the arm.

Having now'particularly described and ascertained the nature of our invention and in what manner the saine is to be performed, we declare that what We claim isl. Ina fire-arm, the combination of the pivoted lever c with the sliding piece o, the barrel or barrels of the arm having lugs@6 underneath to engage with the former, and the firing pin or pins attached to the traverse or traverses E, engaging with the correspondingtrigger and actuated by a spring or springs d, substantially as and for the purpose specified.

'2. In combination with cavities located in the gun-stock, a trigger-guard having slits 10 192193 for the reception of the triggers and lever c, the former pivoted in the lower part of the stock and lying round inside of the trigger-guard, thelatter pivoted within the stock at c and adapted to close round the outside of the trigger-guard, substantially as and for the purpose specified.

3. In combination with a fire arm, the springbarrel with a spiral spring journaled Within the butt and connected to the rear end of the gun-belt, substantially as and for the Y
