magazine-guns; and Vthe objects of the same are to lessen the number of parts in such a gun, to increase the speed in firing, and to` render the working of some of the principal parts automatic. f

lt is illustrai ed in the accompanying drawings, in Which- V Figure l is an exterior side View in eleva'- tion; Fig. 2, a longitudinal section showing the posit-ion of parts in the act of firing; Fig. 2*, a continuation of Fig. 2, showing the spring for throwing back the barrel compressed; Fig. 3, a similar View showing the gun open with cartridge-carrier raised; Fig. 3*, a perspective view of guard-plate and cartridgecarrying mechanism for changing the firingchamber; Fig. 4, a perspective of the swinging and sliding breech-pieces. Fig. 5 is a continuation of Fig. 3; Figs. 6, 7, 8, and 9, details of parts of the cartridge-carrier; Fig. lO, a detail of the sliding sight-plate and extension coveringaspace over the sliding breech-piece; Fig. 11, a plan ot' the sight; Fig. l2, a detail of one of the arms connecting the swinging andsliding breech-pieces; Fig. 13, a detailof forked spring to hold the breech-block up in place; Fig. 14, a cross-section of upper part of metallic case inclosing the sliding breechpiece on line y y of Fig; 2. Fig. l5 is ardetail of a handle for holding the regulator up, as hereinafter described; and Fig. 1G, a detail showing said handle connected to the regulator.

Referring to the drawings, A is a barrel adapted to be slidinside the wooden casingA2 by the action of the ball and a spiral spring S, as hereinafter described, and is inclosed by two short brass tubes Y Y2 at opposite ends of the barrel to reduce the friction. To further reduce the friction of the sliding barrel that part of the stock which receives the bar- Serial No. 388,644.- (No model.)

rel is lined with a leather or clothbushing at to keep out the dirt.

The springS surrounds the barrel and is inclosed in a tubularcham ber S', formed by tube Y2, and the latter is1 held in place byjmeans of a screw ring-plate" S2, as shown in Fig. 5. y

v B is the stock. Y C is a locking-brace pivoted ou a shafto forked and carries between theforks anantifriction roller C?, which rides on theunder curved surface of the locking-brace C. '.Thes: locking-brace C is also provided with al hamnier H, nose h,and a catch C.

E is the firing-chamber, E the storage-chain-V y' g 79' ber, and Eza spiralsprin g in the storagechamber to force the cartridges back. .Y l

F is a sliding breech-piece connected, as

shown in Fig. 4, to the locking-brace C byy arms G. These arms are pivoted to the sides of the piece C by pins and to the sliding piece F by roller-pins C4, which rollers move in grooves C5, formed inthe sides of a receiver C6.

I is the ring-pin placed within the sliding breech-piece Fand having a i'langedhead in a chamber on, a line with the hammer-nose. A spiral spring V is'put around the pin within said chamber bearing against the ange, and the function of which spring is to redraw the pin from the cartridge-head after firing. This withdrawal is aided byy the action of a lever 12, pivoted in thebreech-piece near the tiring-chamber, and the nose of which fits in a slot in the firing-pin. piece `F is also provided lwith a hook I? toengage with and operate a carrier-lever K, as hereinafter described. The head ofthe sliding piece F is provided with a brass tube F2,

The sliding breech-A screwedthereto, which tube has .the function of reducing the friction of the the ring-chamber.- Y

My gun is so constructed that very little gas couldescape from the firing-chamber ou explosion of the cartridge without'making any special provision therefor; but to entirely `pre-- vent such escape I provide at-the inner end piece Fl within of the firing-chamber and at the end of the tube Y disks 14, composedof Va central cork disk and two outer steel disks, compressed slightly on explosion. By this means a per- VIO fectly-tight gasjoint is formed at the junction of the stock and firing-chamber.

The breech-lever D is on the outside of the casing, and, as shown in Fig. l,is provided at its lower end with toothed segment D, which engages with a'rack D2,'sliding in a plate D3, secured tothe casing.

D4 is a slide-rod, onerend of which is secured to the gunebarrel by a short screw-rod t, while the other end is free and adapted to bear against the rack-plate D2. The screw-rod t is placed in a longitudinal slot tain the casing,

and consequently the slide-rod D4 and the barrel have aV movement the length of such slot. The free end of the slide-rod rests on a small roller D6, and D4 has also a curved projection D5 onits underside, which in the rearward movement ofthe slide-rod comes in contact with said roller, rides up thereon, and lifts the slide-rod out of engagement with the rack-bar D2. y

D7 is a spring secured to the barrel-casing with its free end pressing on the rod D4, so that after the latter is lifted, as just described, it will be forced down again on the opposite movement of the barrel.

Ds is a dependent lug on the fastened end of the spring and extending over the side of the slide-rod to hold it in place.

L is a carrier for lifting the cartridges from the storage-chamber to a point on a line with the firing-chamber. The carrier is composed of four parts--namely, the movable cartridgeholder I', (shown in Figs. 3* and 8,) the movable base i2, (shown in detail in Fig. 6,)'on which rests the'cartridge-holder, a stationary yoke t3, on which thecarrier is carried up or down, and the carrier-lever K.

M is an automatic regulator, thefunction of which is to automatically separate a cartridge on the carrier from those in the storage-chamber, and as such cartridge is lifted to follow it up, pressing against those in the storage-chamber and not permitting one of the latter to come forward' onto the carrier until the latter has descended. 'lhisregulator is pivoted at N to a stud rising from the guard-plate P. lts forward end terminates in a nose o,which is forced up between the cartridges, as above explained, and its rear end is forked, embracing the base, to which it is pivoted, the forked ends terminating in a heel o. (Shown in Fig. 9.)

The regulator M is normally held down to the plate by action of a spring-bar M', one end of which is screwed to the guard-plate. The carrier-lever K is centrally pivoted between supports L2, rising from guard-plate P. At its top it is provided with a catch K2, and at its lower end it is provided with a nose K3, which is placed between the lugs ct b in piece a3 on carrier, (shown in Fig. 7,) and with a heel, to which a roller r is secured,which is adapted to ride on the heel o of the automatic regulator. A small spiral free spring L2 is put in from the inne-:sides of standards L2 to an aperture S in the lever to hold the lever in the position in which it may be placed. The lever K is also provided with a flange K4, with which a projection K5 on the ham mer-block engages for the purposes hereinafter described.

Wv is a trigger provided with a nose tu and spring W2. t

Q is a sight-frame and plate. (Shown 1n detail in Figs. 10 and 1l.) This plate is asliding one, 'and through a slot r extends the hammer. The part R of the plate in front of this slot acts as a cover for the opening in the casing over the sliding breech-piece when the gun is not in use.

is a spring secured. to .the stock back of the locking-brace and adapted to press against the head of a sliding bolt x2 in a slot in the stock, the opposite end of which bolt hears against a shoulder x3 at the rear en d of the locking-brace, thereby maintaining a constant pressure of this piece against the sliding breech-piece.

A small spiral spring Q is employed (put between the walls Q2 of sight-plate and bearing against the sides of the sight) to keep the sight in place and against displacement by jars or wear and tear.

P2isa handle on the outside ofthe metal plate of the stock, as shown in Figs. 15 and 16, which carries a half-pin, which is to be put through the casing and con nect with a half-pinp3 on the end of regulator M, whereby, when desired, by turning the handle P2 the regulator is held up so that its nose is held fixed in place over' the mouth of the storage-chamber to prevent va cartridge coming therefrom to the carrier and so that cartridges may be supplied to the carrier by hand, while the cartridgesin the stor` .age-chamber are held as a reserve, or as a single-loader after the cartridges from the storage-chamber are exhausted and the time of recharging the storage-chamber is desired to be saved.

The sliding breech-block F terminates in .two cylindrical parts m2 'm3, through which the tiring-pin also movcs,and which cylindrical parts are separated by a cork disk m4, all covered by tube or sleeve F2. There is a hole through the cork; but the cork presses against the tiring-pin and acts as a gas-check to pre` vent the gas escaping into the back channel of the firing-pin. In the front part m2 the tiring-pin is provided with a slot, through which a pin m5 extends for thc purpose of holding in place the said cylindrical parts and restricting the moving distance of t-he firing-pin. The sight-plate R is also provided with a narrow slot m7 at its rear end.

\Vhen firing, the hammer is forcedthrough the slot 0"; but after firing and when the piece is not in use the hammer is withdrawn from the slot r and said plate R is pushedk forward by hand. Then the hammer is raised and the plate is pulled back a little, so that the hammer enters the slot m7 and is held in place and against accidental displacement and discharge, andjust before the piece is IOO ITO

-zine be filled and the parts be in position indicated in full lines in Figs. 1, 2, 4, and 5. Then by giving the breech-lever D a forward push the locking-brace C, secured tothe shaft of the lever, willbe turned down and the sliding breech-piece F pulled back, the arms taking the position indicated by dotted lines in Fig. 2. The sliding back of the piece F uncovers the firing-chamber, and as it slides back the hook I3 on breech-piece F engages with catch K2 on the upper end of the carrier-lever K, throws the head of said lever backward, and its toe K3 upward, which toe, extending between the forks a b of the cartridge-carrier L, lifts the carrier, together with a cartridge thereon, to the level of the tiring-chamber, as shown in Fig. The heel r of the carrier-lever at the` same time forces down the heel 0 of the regulator M, carrying its toe up between the cartridge on the carrier and those in the storagechamber and holding the latter in place. lV hen the locking-brace descends, its catch C engages with the catch w on the trigger and is locked thereby until released by the pull- .ing of the trigger. \Vhen t-he trigger is pulled,

of the ascending hammer H on the flange K4- of carrier-lever K, and the regulator M at the same time forced down by the action of the spring It Then the hammer and the head of the carrier-lever are'up, as shown in Fig. 2, the projection K5 on the hammer also serves to prevent the carrier f rom being accidentally turned backward. As the cartridge is carried into the firing-chamber by the sliding breechpiece the firing-pin carried by this breech-piece follows it, and at the moment the cartridge is in place the nose h of the locking-brace C strikes the head of the tiring-pin and drives it against the cartridge and explodes it. .The firing-pin is retired bythe action of the spring V and lever I2, the upper end of which lever as the breech-piece is carried back strikes the guard-plate R, which forces the guard-plate a little distance, as before described, and then the lower end of the lever in the slot of the firing-pin is carried forward, accelerating the outward movement of the tiring-pin. lVhen the cartridge is exploded, the barrel is carried forward by the force of the escaping ball against the wings of the barrel and tothe extent of the slot t3 in the casing, as before stated. For this purpose the barrel must slide very freely, and hence the employment of the metal anti-friction tubular bearin gs Y Y2, before described. By the -forward movement of the bal-.rel the spiral sprin g surroundinfs` and in contact with it is compressed against the tube YS, and then afterdischarge the springrecoils, carrying the barrel back with it. The barrel having secured to it the slide-rod D, as be-A fore described, the recoil of spring and barrel serves to move back the rack and set the breech-lever, which engages' with it for the -next operation.

It will be observed that the only manual action necessary in working the gun after it is loaded is pulling the trigger, the rest of the movements being'automatic. It will also be seen that many parts of my invention may be varied as to form and yet accomplish the same functions. I do not wish,therefore, to be understood as continin g my claims to the precise features in all respects herein described, but to embrace their equivalent mechanisms.
