IMPROVEMENT IN `REVOLVING FlRE-ARIVIS.

Specification forming part of Letters Patent No. 43,606, dated July 19, 1864; reissue No. 5,631, dated October 28, i873; application tiled May 9, 1873.

To all whom it may concern:

Be it known that I, JACOB RUrEnTUs, of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented Improvements in Revolving Fire-Arms, of which the following is a specification:

My invention consists of certain improvements, fully described hereafter, in tire-arms having barrels or cylinders containing a number of chambers.

In the accompanying drawing, Figure l is a side view of my improved revolving iire-arm 5 Fig. 2, a longitudinal section; Fig. 3, an end view ofthe barrel-5 Fig. 4, a transverse section on the line l 2, Fig. 2, looking in the direction of the arrow.

A represents the stock and frame, and B the barrel of the latter, having, in the present instance, eight bores or chambers, a, arranged in a circle around a ce1 xtral chamber, b. D is a tubular breech-pin, onwhich the barrel turns, the central chamber, l), being reduced in diameter near its rear end for the reception of the said breechpin, the head d ofwhich bears against a shoulder,

c, the outer end being screwed into the frame,

and a tubular projection, j', a f the rear end of the barrel being arranged to tit into and turn in the said frame. Between the frame and the rear end of the barrel intervcnes a circular and movable breech-piece, E, a flange, h, on which overlaps the edge of a circular plate, fi, formed on the frame, on which plate, as well as on the tubular projection f of the barrel, the breechpiece is arranged to turn to a limited extent. It should be understood that the bores of the barrel are arranged for the reception at the rear) of the ordinary metallic cartridges, the lianges of which intervene between the rear of the barrel and the breech-piece, a notch, m, being cut at one point in the latter to permit the end of the hammer to strike the flange of that cartridge which is contained in the uppermost bore'of the barrel. The breech-piece E and the circular plate t' of the frame are cut away at one point, as seen in Fig. et, so as to afford room for the introduction ofthe cartridges into the bores of the barrel. To the breech-piece, near the point thus cut away, is hinged a door, lr, which, when closed against the said breechpiece, covers the part thus cut away; but which, when open, as seen in Fig. 4, permits the in troduction of the metallic cartridges into the bores of the barrel. rlhis door is provided with a lip or projection, a, and has a notch, q, which, together with a notch, t, at the rear of the breech-piece, will be alluded to hereafter. The rear end of the tubular projection f is provided with angular teeth, similar to those on the cylinders of other revolving nre-arms, the

teeth being acted on by a dog, which is caused to turn the barrel during the cooking of the hammer.

As the hammer, dog, and locl: are similar to those of other revolvinglire-arms, it has not been deemed necessary to illustrate them in the drawin 0'.

To the trigger II, which is also of the usual construction, is secured the spring I, the upper and rounded end of which is arranged to engage into the notch t of the breech-piece, and into the notch q of the door.

It will be observed that the barrel, although containing alarge number of bores, is rendered very light by its peculiar construction.

rlhe bores of the barrel, instead of being parallel with the axial line 5, round which the barrel revolves, as in other tire-arms of this class, all converge to one point inthis line; in other words, the center of each bore at the front end i of barrel is nearer to the axial line 5 than at the rear end of the barrel. By this arrangement, and bythe formation of the central chamber, b, I have been enabled to form a very light barrel, and yet one of appropriate strength. The barrel is rendered still lighter by removing from its outside, at points a, Fig. 3, between the bores, as much metal as possible, taliing care to le( ve at a point parallel with the center of each bore a longitudinal ridge, y, by means of which the proper sighting ofthe iirearm is effected. A rod, K, passes through the center of the tubular chamber b, and ts into the tubular breech-pin D, in such a manner that it can be readily drawn therefrom and used as an instrument for forcing the spent cartridges from the rear of the chambers.

After the breech-piece has been moved to the position shown in Fig. 4 and there lightly held by the spring I, the operator can depress the door G and introduce a cartridge into one of the chambers of the barrel, the latter being turned until a cartridge can be inserted into another ehaniber, and so on until every chainber is charged, after Which the door G 1s closed, and the breech-piece is turned baek in a direction contrary to that pointed ont by the arrow,

4, and until the lip n of the door eonies in Contact With the frame A, and the end ot' the spring I enters the notch q, When the firearm is in a condition to be discharged.

In thus loading; the -tire-arm no aeeidental discharge of the cartridges can take place, for when the loa-ding is being effected the notoh m in the breeolrpieee, through which the hammer ninst pass, is turned away from the Course of the hammer, so that the latter, should it aceidentally fall, cannot reaeh the charged anges ot' the cartridges. The same safety can be in snred when the loaded fire-arm has to be earried in the pocket, by tnrning` the breech -pieoe to the position shown in Fig. t.

It will be evident that the tubular breeohpin for the reception of a discharging-rod and 4 the peculiar method of constructing the barrel arev applicable to the cylinders of ordinary re- Y'olyin g fire-arms.

I claim ne my inventionl. The combination, in a lire-arm having a manyehambered revolving cylinder or barrel,

of a fixed tubular basepin and a detachable shell-discharging pin, as Specified.

2. A breech-piece, E, intervening between. the rear end of the barrel and the frame, and arranged to turn substantially as set forth.

3. The notoh m, formed at or near the edge of the said breech-piece, as set lt'orth, for the purpose speoiied.

4. The Combination of the said `movable breech-piece with the door vGr or its equivalent.

5. The said movable breech-piece, With its notches. t and q, in combination With the Spring I. 4 j

In testimony whereof I have signed 1n y name to this speeitieation in the presenee'of two' snbscribing witnesses.

JACOB RUPERTS.
