BREECH-LOADING FIRE-ARM.

SPEOIFIGATIO K forming part of Letters Patent No. 258,923, dated June 6, 1882.

Application filed January 27, 1382. (No model.)

To all whom it may concern:

Be it known that I. FRANK A. V'HOLLIEN- BECK, of Syracuse,in the county of Onondaga,

in the State of New York, have invented new and useful Improvements in Breech-Loading Fire-Arms, of which the following, taken in. connection with the accompanying drawings; is a fnll, cle ar, and exact description.

, This invention relates to certain novel devices for operating a tliree-barreled gun by only two locks and hammers,- and also has reference to various improvements in the construction of breechdoading guns generally, and

in the mechanisms essential to the successful operation of the same.

" The invention is fully illustrated in the an nexeddrawings, wherein Figure 1 is a longi-,

tudinal section of my improved"breech-loath, p g fire-arm. the forwardpos tiQlL of id sectlon being taken along the side of the usual lug on the under side of thebarrls, the rear part of the section being taken on the line parallel with the shifting-bar, which bringsthe tiring-pin, of thethird barrel into operation with the hammer of the gun. Fig. 2is a side view, showing the barrels in a tilted position.

Fig. 3 is a transverse section on line mm. Fig..

i 4 is a face view of the breech of the barrels.

Fig. 5 is adetached top view of the breech block or frame. Fig.6 is a view of the under:

of the barrels on line y y. Figs. 8 and 9 are enlarged detail views of the sight audits don nection with the gun, and Fig. 10 illustrates modifications in the construction and arrangement of the shifting bar. 7 Similar letters of reference: indicate correspending parts.

care placed in their operativeposition on the breech-block or frame, as shown in Fig. 1 of the drawings. By the engagement of the for ward face of the lug 1 with the rear face of a bridge, L, on the breech-extension between the two recesses or mortises I and l the recoil of the gun, when fired, is counteracted and the hinge-pin F relieved :of the strain incident to the tendency of the separation. of the barrels is hinged a link, p, the free end of which has its cross-bar passing through an inclined slot, o,in the forward lug, i. The sloto is extended through the rear end of said lng,'and ter ninates with a notch, 0', in the upper face of the lower portion of the slotted lug, as best seen in Fig. l of the drawings. [In tilting the barrels, as shown in Fig. 2 of the drawings, the free end of the link is drawn toward the rear end of the slot 0 and drops into the notch .95". th rebl arresting cthetmovemeutwof the of the resultant strain.

Erepresents the extractor ,rel 0, said extractor having a forward-e. tended tongue, is, which slides in alongitudinal groove or channel, 7:, in the lugs 'i i, and

end against the cross-bar-of the free end of the link p when said extractor is in its dormant position and the barrels brought down upon' the breech-block or frame. The extractor is secured in the groove It by an extra plate, L W'l ich' is removably attached to the bottom oftlie lug i, so as .to facilitate the"const ruc-. tion arid repairs of the groove constituting the guide for the extractor the said extractor is provided with a longi tndiual slot, m, through which passes a screw or. pin,' n, said pin, serving to prevent the extractor from slidingout endwise and becoming lost when slot m is of such a length as to allow the ex tractor E-to carry the for said lug whenever it is desired to the barrels from the stock.

ed to engage'the primed and of the cartridge.

from the stock. To the sides of the bridge L 19' barrels and-relieving the hinge of the barrels is of sufficient length torest with its forward inserted transversely in thelug i;

the barrels are detached from the stock. The 4 be pushed rearwardsnfiicient to ward end of the tongue k out of the log t, and thus allow the free end ofthe link p-to he swung out of its engagement with disconnect D represents the extractor'for the shotgun-rep barrels B B, it consisting of a plate, It, adaptor shell, and having a forwardlyextended stem sliding in a channel in the metal between the two barrels B B. The extractor D is operated by the extractor E, which has a shoulder, 9, engaging the rearof the plate h of the extractor D, and thus forces the same rearward or outward simultaneously with the rearward movement of the extractor E.-

a and aare the firing-pins for the respective barrels. Said firing-pins movejn bushings t-in therear end of the firing-pin of one of the shotgun-barrels and of the firing-pin of the riflebarrel, said shifting-bar being provided with two apertures, r 1', arranged in such relative positions that while one is in coincidence with its adjacent firing-pin the otherapertureis normally out of coincidence with its respective fir-' ing-pin. The shifting-bar has a lateral as well as a sliding movement, and is by means of a spring, 6, held normally in such a position as to bring the aperture 7" of saidbar in coincidence with the firing-pin ot' the rifle-barrel, and by means of springs e and a pressing against the shifting-bar, respectively at the base and upper portion thereof, said bar is held yieldingly rearward, so as to allow the two tiring-pins to be repelled back into the recoilplate or breech-block by the rebound'incident to the firing of the barrels.

Back of the upper end of the shifting-bar s, and in range with the firing-pin of the shotgun-barrel, is a plunger,-b, provided with an axial cavity, 0, adapted to receive the rear end of the aforesaid firing-pin, as hereinafter explained. The aforesaid position of the shiftin g-bars brings the solid portionthereof across the rear end of the firing-piuof the shotgunbarrel. Thus when the plunger b is struck. by the hammer H said plunger throws the shifting-bar aforward, and-the latter in turn propels the firing-pin ot the shotgun-barrel and discharges said barrel, while the lower aperlure, r, of the bar 8 allows the firing-pin ot'the rifle-barrel to pass through said aperture, and

. thus prevent the simultaneous firing ot' the rifle-barrel. The lower extremity of the shifting-bar s protrudes at the surfaceof the stock, and is provided with a suitable handle, by means of which said bar can be pushed inward, so as to bring the upper aperture, 1', thereof in coincidence with the firing-pin of the shotgun and the solid portion of the bar below the lower aperture, r, across the firing-pin ot' the riflebarrel. A shoulder, d, or other suitable catch on the bar 8, engaging with a shoulder on t e inside of the stock, retains the said bar in i' s aforesaid position. If thegun is then fired, the" firing-pin of the shotgun-barrel passes through the aperture r of the upper end of the shift-' ing-bar and into the cavity 0 of the plunger 1), thus leaving the charge of the shotgun barrel undisturbed, while at the same time the solid lower portion of the shifting-bar forces the tiring-pin of the rifle'barrel forward, and thus discharges said barreL, The forward thrust of the shitting-barscauses the shoulderd thereof to become disengaged, and so soon as this is etfected the spring 0 forces the shifting-bar longitudinally and restores the same to themsition for firing the shotgun-barrels, as before described.

, In order to render the-tripping of the shiftin g-bar adjustable, so as to change itsposition at the proper time, I apply to the exterior of the stock, and in close proximity to the shiftihg-bar, an eccentric screw or button, f, against which the lower extremity of said bar rests. By turning said screw the rearward thrust ot' the aforesaidportion of the shifting bar can be checked to increase or diminish the engage ment of the shoulder d, as may be desired.

The plunger 1) is 'retained in the stock by means of a small screw, it, inserted through the-side of the stock, and engaging with a longitudinal groove in the sideof-the plunger,

as best shown in Fig. 1 of the drawings.

The' rear end of the barrels is locked on the breech-block or frame by means of a'lever, m, pivoted on top of the tang T in the manner hereinafterexplained, said lever passing with its forward end through a laterally-enlarged channel, which is extended through the solid portion of the breech-block, and thus completely incloses said end of the lever m and efleetually sustains the same to resist the upward strain when interlocked with the rear end of the barrels. The described channel allows the lever to swing laterally and engage a notch, N, in a rearwardly-extended book, 0,

on the breech of the barrels, said hook enterv ing a cori'esponding mortise in the upper part of the breech-block. The lever M, I provide with an "eye, by which I pivot it on a cylindrical projection or boss, 1, on top of thetang T and integral therewith, in the center of which boss is a hole, 2, extending vertically through the tang. In this hole I insert the stem 3, which .carries thesight 4, saidstem being provided with a vertical slot, 5, through which passes a pin, 6, inserted through the side of the tang. Between the rear side of the stem 3 and the.

adjacent side of the hole 2, I place a spring, 7,

which by frictional hold on the saidstem retains the sight in its desired position. The upper end of the spring 7 is extended over the top of the boss 1 and over a portion of the lever M, and thus forms a key to hold the latter down upon the tang. 1

1? represents the so called fore-end ot' the gun, and Q the tip-strap, which rests against the forward end ot' the breeeh -cxtension'G,

and in conjunction with the bearing of the lug t" against the hinge-pin F completes the connection of the barrels with the breech-extension. Heretofore the fore-end and tip-strap were'firtnl y united and operated as ifformed in one piece.

. Consequently it was exceedingly diflicult to render the same adjustable so as to compensate for the wear of the bearing of the ti p-strap on the end of the breech -extension,.although it has been attempted to accomplish the said object by means of a spring pivoted on the combinedlipmtrapandfiireemi, and bearin g with its free end on a lug on the under side of the barrels, yet the construction and arrangement of the spring were such that a slight wear and secured thereto by a. screw or screws passing through said parts.---

adjacentportion of each other with @strap to take up thewe'ar and abrasion of its joint with the end ing the thumbo i' The tip-strap consists of a metal-block, fitted at its rear end against the forward end of the breech-extension, and having its forward end beveled to fit .to the sh ank R aforesaid. In the beveled end of the tipstra-p there is g S, in which is placed a spring, U, in the form of a bow, which has its rearend hooked onto a book, 8, in the rear end of the mortise.

Thefonward end of the springs projects into a mortise in the shank R and in the fore-end, and is formed with arearwardly-inclined or reversed curved face, V, which bears on a stud, 9, or other suitable shoulder in theinortise of the shank It, and thereby crowds the tip-strap upward against the said shank and rearward against the end of the breech-extension, and by the latter action causes the tipthe lost motion incidentto of the breech-extension. The free end of the spring U terminates with a rearward extension, 10, which passes underneath a cross-pin,

.11, in the tnortisd of the tip-strap, and thus retains said spring, in the mortise. The spring U has suflicient elasticity to allow the forward end of the tip-strap to be pulled out by applyfinger in a recess, 12,, and the un'der side of the tip strap; The upper end of-the shank It and the asegmental face, 14, which is concentric with the hinge ot' the barrels, and at thesaid face-there are two set-screws, 15, in- Q."

the tip-strap are fitted to It is obvious that the herein-described shifting-bar s can be arranged in various ways, and I therefore do not limit myselfin that respect. One of the modifications of the construction and arrangement of the shifting-bar is illustrated in Fig. 10 of the drawings, and consists in terminating said shifting-bar inside of the breech-block and connecting thereto a pivotal lever, 16, which-projects through the side of the breech-block. By depressing the outer end of said lever the shifting-bar is moved upward to bring the-solid lower portion thereof nverthe'flriifg piiibt' marine-barrel, and simultaneously bring the aperture in the upper end of said bar in coincidence with the firing-pin of the shotgun-barrel. A reverse movement of the lever 16 restores the shifting-bar into rifle-barrel and for firing the shotgun-barrel.
