- GUN AND PROJECTILEFOR THE SAME'I SPECIFICATION forming part ofy Letters Patent No. 398,595, dated February 26, 1889.

Application filed May 1, 1888. Serial No. 272,469. (Nd model.) i

.the following is a specification.

The primary objects of this invention are to simplify the actionot' breech-loading firearms and to augment the efficiency of smoothv section on the line x, Fig. l.

bores, which objects I accomplish mainly by dispensing with the ordinary cartridge-sh ells, which have to be ejected from the piece after each discharge. j

The invention consists in certain novel coinbinations of parts, hereinafter set forthy and claimed. i v

A sheet of drawings accompaniesthisspeciication as part thereof. Figure l of thesev i l drawings represents a longitudinal section of a pistol with its breech open. Fig. lX represents a side View of the front end of the pistol with its breech closed. Fig. 2 represents a longitudinal section of the pistol with breech closed and ready for tiring, showing a sec-' tional View of the proj ect-ile within the barrel. Fig. 3 is an end view'of the pistol, showing its breech end. Fig. 3*' represents a cross- Fig. Ltis a top view of the pistol as seen in Fig. 2. and 6 are perspective views of the projectile before and after its discharge.

Like lett-ers of reference indicate corresponding parts in the several figures.

The projectile forming part of this invention is composed of a head, A,4wliich may be of lead or other metal, and a tube, B, which may be cut from drawn metal tubing of snitable weight and diameter. One end ot' the tube is provided -with an internal screw-thread, andthe head A is tightly screwed into the saine.. The other end of the tube, hereinafter termed its rear end, is chanibered or enlai-ged internally for about one-sixteenth of i an inch from its extremity, and the wall of l the cliainbered portion is slightly expanded to render the rear end of the projectile originally flaring inform, as shown in Figs. 2 and 5. -The ltube is Vloaded with1 gunpowder or any other suitable explosive up to the commencement of the chamber, and the charge Figs. 5k

is then completed by thin layer or disk, d, of any suitable detonating explosive, which rests on the shoulderof the chamber, as shown in Fig. n

The barrel B of the fire-arm proper is a straight cylindrical tube of metal, having the inner angle of its rear end chamfered to form aseat, c, for said Haring rear end of the projee-tile. The barrel is furnished externally near its rear end with two diametrically-opposed p'. ns or studs, b,and slides within an o uter tube, C', which is provided with bayonet-joint slots j in its respective sides to accommodate and coact with said studs on the barrel. An opening, o, in the top of said tube C provides for the insertion of the projectile when the barrel is pulled forward, as shown in Figs. 1 and 3. When the barrel is forced backward to its rear position, (represented in Figs. lx, 2, and 4,)

said studs come opposite the locking ends of said bajfonet-slots, and a slight twist of the into said .locking barrel brings said studs y In this position of ends, as shown in Fig. l.

` the barrel the projectile is clamped against an end abutment, E, foi'iiied..witliin said'tube C"nearits rear end, andl` provided with a small hole, through which. the ring-pin F may be projected. Said tube C' isv extended behind said abutment 'E to forni a guidechaniber, within which a piston, D, Works between a pair of spiral springs, S S2. This piston carries the firing-pin F,aroiind whiclione of said springs is conveniently placed. The other spring, S, surrounds a )fiat stein, G, connecting said piston D with a cooking-knob, H. A hollow plug, I, behind said tube C 1nwithin the rear end of the tube CA. The rear end ot' said plug I is closed, except a hole through which said stein G works back and forth. Behind this closed end a vertical chamber is formed in a projecting upper portion of the pl ug, and within this vertical chainber a spiral spring, S, is compressed bya piston, K, composed of a pair of small disks rigidly niiit-ed by a central stem, which latter extends through a longitudinal slot formed in said stein G and knob H, as indicated by doi ted lines in Fig. l. 'When the pieceA is cocked by pulling said knob H, the upper disk of said piston K descends in front of the -closes said spring S, the interior `of the plug forming a coiitinuation'of said guide-chamber knob, as shown in Fig. 2, and prevents the premature or accidental projection ofthe firing-pin.

For discharging the piece, a disengaging-lcver, L, is pivotcd below said tube C and plug l. In the example said lever is in the form of a bell-crank with a relatively long arm, the extremity 'of which is upturned to engage' with the pist-on K, and with its other and shorterarm coupled to the loosely-sliding stem of a trigger-button, M.

' D becomes compressed owing to the momen- I' tum of the piston, so as to permit the projecl A touch on the button M brings the lever L into contact with the lower disk of the stoppiston K, as shownin 'dotted lines in Fig. 2. A slight pressure on the button then lifts the piston against the pressure of the spring S8, sc as to disengage its upper disk from the knob H, whereupon the main spring jS projects the piston D and therewith the. tiringpin F, causing the latter to penetrate or to strike and explode lthe detonating-disk d, which explodes the charge C within the project-ile. The spring S2 in front of the piston tion of the firing-pin- Its recoil partly retract-s the firing-pin, t-he point of which Qis normally masked by the abutment E, owing to the-reaction of said spring S2.

A stock-tube, T, is internally screwthreaded, and 'tube C and plug I are s: rzwed into its respect-ive ends.

andlling of the stock are secured' in customary manner.

It will be understood that the form and dil mensions ot the Weapon and its stock may be varied from those suitable for apocket-pistol up to those suit-able for a powerful shoulder arm. f'

of power caused by riding, `while the tube B causes the propelling-gases to rush from the projectile to the-breech instead of vice versa, so that there is no loss by wi'ndage. Moreover, the great comparative length of theprojectile, the facility with which it maybe centered by properly adjusting the weight of the head and the tube, and the heavy charge of powder that maybe safely used all contribute to the great range and accuracy obtainable by the use of tire-arms constructed 'in accordance with my invention.

A pair of framei plates, U, project downward from the stocktube, and to and between these the 'cheeks .The smooth-bore barrel avoids the waste l,

' Having thus described my said improvement in tire-arms, desire to patent under this specificationl The combination, substantially as hereinbefore specified, of a projectile composed of a head and a rearwardly-projecting open-ended tube,which latter contains the charge and is formed with an expanded rear end, andarearm having the rear end ofits barrel open and the bore, and a firing-pin projected through a hole in said abutment to explode lthe fulminate, substantially as hereinbefore specified. i 3. The combination, substantiallyashereinbefore specified, of a projectile composedof a head and a rearwardly-projecting tube, the

1 latter having its rear end cham'bered and exl panded, a sliding smooth-bore barrel having t its rear end internally chamfered and proouter tube having bayonet-joint slots and a projectile almittng opening, and provided wit-l1 an internal abutment behind the bore of the barrel, a piston behind said abutment provided on its respective sides with a firing-pin and a stem, and a pair of spiral springs-on g the respect-ive sides of said piston,for the purl poses set forth.

4. In combination with the spring-projected piston carrying the firing-pin and having on its back a at stem which is slotted and'pro p vided with a terminal cooking-knob, aspring- 1 projected stop-piston at right angles thereto, g `having a stem which passes through said slotted stem, and a disk which coacts directly i with said knob, and a disengaging-lever actt ing on said stop-piston to tire the piece, substantially as hereinbefore specified.
