FRANCIS SOHOPP, OF NEW YORK, N. Y.

IMPROVEMENT IIN BREECH-LOADING FIRE-ARMS.

Specification forming part of Letters Patent No. 51,225, dated November 28, 1865.

To all whom it 'may concern:

Be it known that I, FRANCIS SCHOPP, of New York, inthe county and State of New York, have invented anew and useful Improvement in Pistols; and I do hereby declare that the followingis a full and eXact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure I represents a longitudinal section of my improved pistol. Fig. Il is a section of the movable breech. Fig. III is a front view ofthe same; Fig. IV, an end view, and Fig.

V of top view, of the breech.

The nature of my invention consists in the arrangement of a movable breech, sliding horizontally and containing two charges capable of being red off successively.

In the accompanying drawings, Arepresents thebarrel tirm l y secured to the stock or breechframe B. O is the cock, D the trigger, E the lock-spring, and F the trigger-spring, constructed in the usual manner.

The opening through the stock or breechframe B is made square, into which a square breech, G, is fitted perfectly tight, capable of moving sidewise or horizontally, and provided with two openings, 'm m', to receive the car- On the lower side, near the after end of this breech-piece, a projection, a, is made, extending the whole width of said breech -pieee G, and provided with recesses'o o', made with slanting sides, into which said recesses a pin, s, arranged in a suitable hole in the lower part of the breech-frame, B, is made to work. This pin s is acted upon by a spiral spring, e, situated behind said pin s, so as t force said pin into the recesses o or o', and to keep thereby the breech-piece G fast in either one or the other position.

The cock C being placed in the position represented in the drawings, or at half-cock, the breech-piece G can be moved sideways sufficient to introduce a cartridge into one of the openings, m, at the side of the breech-frame on the other side of the breech-frame.

when the breech-piece G is moved in the other direction, so as to charge the other opening, m', The breech-piece G is then moved so that the recess 2 between the two openings m m (see Fig. 1V) comes opposite the end of the cock C, when said cock O may be brought to rest, falling into this'reeess'2, and holding thereby the breech-piece G in that position, when the now loaded pistol canV 'be carried with perfect safety in the pocket.

The bottoms of the recesses o and o correspond with the center lines of the cartridgechambers m m', but the inclined side of the recess o toward o is carried farther over than the center of the breech-piece G, by which arrangement the pin s will stand upon this inclined surface, when the breech-piece G is in the center held fast by the cock O, as above described.

When the pistol is to be red off the motion ot' the cock C to half-cock will liberate the breech-piece G, when the pin s will act against the inclined side of the recess o so as to move said breech-piece G in a Inanner that the eartridge-ehamber m will come in a line with the barrel A, ready to be tired oft', after which the breech-piece can be moved by the tinger so that the pin s comes into the recess o', whereby the cartridge-chamber m will be brought in a line with the barrel A, ready to be tired ott', when the breech must be reloaded.

I do not claim, generally, a double-chambered square sliding breech-piece; but

What I claim as my invention, and desire to secure by Letters Patent, is-

'Ihe pin s, acted upon by a sprin g and operating the breech-piece G, in the manner and for the purpose substantially as set forth and specified.

FRANCIS qSCHOPP.
