MAGAZINE FIRE-ARM.

SPECIFICATION forming part of Letters Patent No. 293,315, dated February 12, 1884.

Application filed December 3, 1883. (No modcl.)

To all whom it may concern-.-

Be it known that I, W. H. ELLIOT, a citizen of the United States,residing at New York, in the county of `New York and State of New York, have invented a new and useful Improvement in Magazine Fire-Arms, of which the following is a specification.

Theobje'ct and nature of my invention may be described as follows:

The object of my invention is to vprovide a cheaper and safer magazine lire-arm than any now in use; and the nature of my invention consists in the use of certain appliances and methods, which are fully set forth in the following specification and claims.

Figure 1 is a verticallongitudinal section of my improved arm, showing some ofthelimbwork in elevation. Fig. 2 is an elevation of a portion of the limb-work, showing the position of the same when the chamber is open. Fig. 3 is a plan of the brace, showing smaller parts attached thereto. Fig. 4. is a front elevation of the bolt. Fig. 5 is a vertical crosssection of the arm through the operatinghandle. Fig. 6 is a vertical section of the brace, showing the levers for starting it' from the recoil-shoulders. Fig. 7 is a planof the carrier.

My invention is Vapplicable particularly to that kind of arm which has atubular magazine arranged under the barrel, ,and a bolt or breech-block'which moves in a line with the barrel .to close the chamber. It is also applicable to arms having detachable magazines.

The receiver a has' the barrel b screwed into its forward end in the usual way. It also supports the guard-strap g. This latter device has upon its forward end an upward-project-- ingv portion, g', which is bored through to' receive and support the rear end of the -magazine-tube t. The upward projection, y', is provided with two lateral projections-one upon each side-which rest against the forward endA of thereceiver and serve as recoil-shoulders, as shown in my patent of September 18, 1883.

The breech-block ismoved back and forth,

locked, and the carrier operated by means substantially such as are shown in my patent may be formed upon the guard-strap or upon The the receiver, as shown in said patents.

upper edges of the hollow handle a run in and are supported by parallel grooves b,cut in the barrel above and independent of the magazinetube t and,` guard strap, as shown in Figs. 1 and 5. This handle is provided with a connecting-strap, h, which extends backward into the receiver, and is at its rear end connected with the breech-block by'means of the downward-projectingarm or link ofthe brace d, said arm being pivoted at its lower end to the rear end of the connecting -strap at IL', and is also connected atv its upper end, through the brace d, with the breech-block at c, whereby the rear end of said connectingstrap is held to a substantially parallel movement by the breech-block, independent ofthe guard-strap as aguide or support. These lastmentioned features are among the most important of my invention. The grooves or guides for the handle being 'in the` barrel or above the magazine-tube, they are in almost a direct line with the movement of the breechblock. There is, therefore, less tendency to lateral pressure and consequent friction than there would be if the guides for the handle were in the guard-strap, as shown in said patents.

By providing guides for the handle above and independent of both the magazine tube and guard-strap, the constructionof the guardstrap becomes much less expensive, as the long grooves for the connecting-strap 4and the eX- tension of the guard-strap forward of the receiver are both dispensed with. In addition to these advantages there is still further the advantage of having'the magazine-tube independent of allof the moving parts of the breech mechanism, as in thatv case the breech mechanism can be assembled and its movements tested without having the magazine in its place, and the magazine may be taken out for repairs or cleaning without disturbing the rest l also forms a recess, r, for the reception of the of the arm; and while out the arm may be used as asingle breech-loader as practically as with the magazine in place, which is sometimes very desirable. The carrier sis pivoted near its rear end, and is provided with an upward projection, s', in rear. of its pivot, whereby its forward end is raised by the brace during its backward movement, as shown in Fig. 2, and is depressed to receive a cartridge from the magazine by the inclined surfaces e and e on the forward end of the breech-block.' The carrier is slotted or bifurcated, as shown in Fig. 7, the two sides being connected together at the forward end by the bar s, and vmay-be similarly connected at the rear end, if so desired. As the arm is being closed, the surface e, moving along upon the carrier, partly depresses it, when the surface e', coming against the bar s, forces the carrier down to the position shown in Fig. 1.

l v By reference to Fig. l it may be seen that the surface of the rear end of the brace d is cut eccentric to the axis of that device, and concentric with the center t' considerably above the axis of the brace; also, that the shoulders d on each side of the brace, being struck from the same'center, are parallel and equally' eccentric to the said axis. The recoil-shoulders g arerigidly supported by the receiver,

. and have a for-m corresponding with that of the end of the brace cl, so that the downward movement of the rear end of the brace, acting against the recoil-shoulders, carries the bolt forward with great force, to complete the insertion ofthe cartridge. The pins or shoulders m project rigidly from the inner surface of the receiver, and rest against the eccentric surfaces d', so that when the brace is raised in the act of opening the chamber, the pins m, acting upon the eccentric shoulders d', cam

' the bolt back with equal force to start a shell that sticks in the chamber.

By reference to Figs. l, 3, and 6 it may be seen that the arm d" of the brace is pivoted to that device at 0', and has a limited movement in relation to it, without affecting its function of moving the bolt; also, that the said arm has a projection backward at its upper end, which rests against the under side of the rear end of the lever o, which is also pivoted to the brace at o', and rests at its rear end upon the top ofthe recoil-shoulders g. When in the manipulation of the arm the lower end of the arm d is carried backward, it acts as a lever to raise the forward end of the lever o, which,

' in turn, acting upon the top ofthe recoil-shoulcentral portion of the rear end of the brace when the bolt is back and the chamber open. By this construction of the hammer the rear end of the receiver is kept at all times closed, and room is provided for the carrier and brace Without increasing the length of the receiver for that purpose.

Having described my invention, what I desire to have secured to me by Letters Patent of the-United States is- 1. The combination, in a magazine fire-arm, of the longitudinally-reciprocating strap h, pivotally connected at its rear end to the arm d of the bracevof the breech-block, and having at its forward end the handle a, with in- 'wardly-projecting arms or edges, taking with the grooves or guides in the barrel above and independent of both the magazine-tube and the guard-strap, whereby the handle is supported and guided independently of said tube and guard-strap, and the rear end of said connecting-strap is guided by the breech-block, substantially as shown and described.

2. In a magazine fire-arm, the construction and combination of devices substantially as follows: a breech-blockl for closing the chamber, movable in a line with the barrel, actuated by a longitudinally-reciprocatin g handle, n, arranged forward of the receiver, through a suitable connection therewith, and having upon its forward end the inclined surfaces or cams e and c', a bifurcated or slotted carrier pivoted at its rear end and provided with bar s, upon which said surfaces act, whereby the carrier is depressed from its highest to its lowest position by the'said inclined surfaces during the forward movement of the breechblock, substantially as specified.

3. In a magazine lire-arm, a breech-block, movable in a line with the barrel,bearing the pivotally-connected brace, and having the ec; centric bearing-surfaces cl, for forcing the cartridge into the chambenand d', for starting the cartridge-shell out of the chamber, in

combination with the receiver having the sta- A tionary shoulders g and m rigidly fastened thereto, whereby the cartridge is forced home in thechamber, and the shell is started out of the chamber by the alternate raising and lowering of the brace, substantially as shown and described.

' 4. In a magazine fire-arm, a breech-block provided with a brace for resisting the recoil ofthe charge, which brace abuts upon suitable recoil-shoulders that are formed eccentric to the axis of the brace and are supported by the receiver, and in combination therewith the two levers d and o, both being pivoted to the brace and acted upon by the devices that give movement to the breech mechanism, to displace the brace from the recoil-shoulders, substantially as specified.

, 5. In a magazine re-arm, a hammer havving the curved projection r extending forroo Ward from the face of the hammer under the end of the brace occupies said recess when rear end of the bolt, and the recess r under the arm is open, andthe rear end of the re- 1o said projection, in combination with the carceiver is kept all the time closed7 substantially rier s and brace d, the vparts being arranged as shown and described.

in such relation to each other that during Y WM. H. ELLIOT. the manipulation of the arm the rear end of Witnesses: the carrier occupies therecess r when the G. J. EHBETs,

' arm is closed and the hammer down, the rear` S. F. FRASIOK.
