MAGAZINE FIRE-ARM.

SPECIFICATION forming part of Letters Patent No. 278,324, dated May 29, 1883.

Application tiled March 10, 1883.

To all whom it may concern:

Be it known that 1, WM. H. ELLIOT, of New York, county of New York, and State of New York, have invented a new and Improved Magazine Fire-Arm, of which the following is a specification.

The object and nature of my invention may be described as follows:

The object of my invention is to provide a simpler, cheaper, and more rapid fire-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 in Sheet 1 is a vertical longitudinal 7 section of myimproved arm in the closed position, showing thelimb-work in elevation. Fig. 2 is a vertical cross'sectiou of the arm at as, Fig. 1. Fig 3 is an elevation of the chargeopening cover. Fig. 4 is a plan of the guardstrap,showing the connecting-strap supported upon and sliding therein. Fig. 5 is a bottom view of the handle, with its locking-spring. Fig. 6 is a horizontal section of the receiverin the axis of the magazine. Fig. 7 is an elevation of the brace. Fig. 8 in Sheet 2 is a vertical section of the receiver, showing the barrel, magazine, and limb work in elevation, the arm being in the open position. Fig. 9 is a vertical cross-section of the arm at 00",Fig. 8. Fig. 10 is the same at 00, Fig. 1. Fig. 11 is a top view of the brace. Fig. 12 is an elevation of the brace, firing-pin, and a portion of the connecting-strap. Fig. 13 is an elevation of an adjustable mainspring-stop. Fig. 14 is a modification of the invention, showing the breechblock and brace combined.

My invention refers to that kind of magazine fire-arm which has a tubular magazine arranged under the barrel, a bolt or breechblock for closing the chamber, which nioves in a line with the barrel and is operated by means of a sliding handle, with its connecting-strap supported upon and sliding in the guard-strap or other device attached to the receiver. The

receiver has the'barrel screwed into its forwardend in the usual way and is provided with the recoil-shoulders c, which are formed in one piece with the receiver and project from the inner surface or sides of the same. The brace 61 is pivoted at c to the breech-block, and at (No model.)

the moment of discharge the surface dofthe brace rests upon the face of the recoil-shoulder c. The brace has an arm, (1, which extends downward and passes through or is joined or pivoted to the connecting-strap c at c. This strap slides back and forth in grooves in the upper side of the guard-strap, and at its forward end is provided with a handle, m, which may project into and be guided by grooves n in the barrel, as shown in Fig. 9. The guardstrap extends tor some distance forward of the receiver, and has the grooves for the connecting-strap continued in the part so extended forward, whereby the handle is guided and supported forward of the receiver independ ently of the barrel or magazine-tube. The strap 0,, being bifurcated atits rear end, so as to pass by the hammer and trigger, as seen at c, Fig. 4, by this means a long bearing is obtained for it in the guard-strap. The upper edges of the plate forming the handle may, if desired, run in grooves in the barrel, as shown at at; but I prefer that the handle be guided and supported entirely by the guard-strap.

The handle has a spring-bolt, m, which fastens it to the connecting-strap, the point of the bolt projecting into the strap, as shown at m. By raising the bolt the handle maybe moved back and fastened against the receiver, for convenience in handling and packing, by permitting the point an" to fall into the notch m. The handle, when so adjusted, occupies the position shown in Fig. 8, while all of the other parts occupy the position shown in Fig. 1. The carrier 0 is pivoted to the receiver at o, and is bifurcated at its rear end to make room for the hammer, as shown at 0", Fig. 6, and for some distance forward of its pivot it is made spring laterally to make room for the cartridge 1) and charge-opening cover 9 when the magazine is being charged-with cartridges. As the cartridges arepushedinto themagazinethe carrier and cover both yield laterally, to let them pass, but assume their natural positions again on being released from pressure. The carrier is provided at its forward end with dependent portion 0, which serves as a stop to the cartridges in the magazine, the strap 0 having in it the opening 0' to make room for said dependent portion when the carrier is depressed thin, as seen at 0', whereby it is adapted to,

' lower end of the arm d is carried backward 2o strap 0. In Figs. 1 and 4 the lower end of the surface projecting rib g, opposite to a correto its lowest position. The carrier is actuated in both directions by the brace, which strikes it in rear of its pivot to raise it and in front ofits pivot to depress it below the mouth of the magazine, as shown in Figs. 1 and 8. The support of the charge-opening cover 9 passes into one of the recesses a above the recoilshoulders, andis fastened to the side of the receiver by screw 9. The cover has on its inner spending projection, b, from the side of the receiver or guard-strap, to hold the cartridges centrally in the receiver while they are being raised by the carrier. The brace d is provided with a projection, n, on the upper side of the joint, as seen in Figs. 1 and 7. This projection, when the arm is closed, rests against the pin or shoulder c on the receiver. When the by the strap 0 in opening the chamber, the arm of the brace acts as a lever of the second order, to pry the breech-block away from the barrel, the face of the recoil-shoulder and the face d of the brace being out sufficiently eccentric to the axis 0 to permit this slight movement in the breeclrblock while unlocking the same. By this lever-action the cartridge is started from the chamber.

An imperfect cartridge-head will sometimes swell out against the breech block with so much force that it requires *great effort to remove the brace away from the recoil-shoulders. To remedy this ditficulty, 1 make a joint, 0, midway in the brace, as shown in Fig- 7. When the lower end of the arm at is carried back the brace first bends upward to the position shown by open lines. This shortens the brace sufficiently to relieve the pressure ofthe cartridge-head against the breech-block. In such case the projection it must not act upon the shoulder 0' until after the brace is bent upward.

By reference to Figs. 1 and'7 it may be seen that the surfaces on each side of the lower end of the arm d at d, which are borne upon by the strap 0 are inclined, so as to counteract the tendency of the force applied by said strap to raise and depress the forward end of the breech-block as it is moved back and forth in manipulating the arm.

I have shown in the drawings several methods of attaching or joining the arm d to the arm is joined by merely passing through the strap. In Fig. 12 the arm at the lower end is pivoted to the strap 6. This method avoids any tendency of the strap to raise or depress the forward end of the bolt as it runs in grooves in the upper side ofthe guard-strap,and holds the breech-block to nearly a parallel movement, and so prevents any binding of the bolt in the rear end of the receiver.

In Fig. 14 amodification of my invention is shown. In this case the breech-block with the brace and arm are made in one piece of metal,

and when the brace is raised above the recoill within the receiver, and the connecting-strap,

being pivoted to the arm d, is provided with a bearing in the guard-strap only at its extreme forward end, the parts being forced to move in aparallel line by the friction-rollers in their grooves. The hammer and rear end of the bolt, it may be seen, are soformed that the hammer can strike the firing-pin only when the'brace is fully seated upon the reeoitshoulders.

The firing-pin i, Fig. 12, has a downward projection, t, and the brace also has an upward projection, i, and these projections are so arranged that the firing-pin can move forward to explode the charge only when the breech-block is fully locked. The firing-pin has a spring, 1', which throws both it and the hammer back to the safety position after the discharge, the mainspring lt=being stopped-at the proper point by theadjustable screw-loop h, the backward movement of the firing-pin being limited bythe pin u.in the oblong opening in the flange a, the lower surface of the projection t' being .cut diagonally, as shown in Fig. 12, whereby the firing-pin is cammed back or retracted by positive movement in case the spring 2" fails to perform its function, or in case it be dispensed with in manufacturing thearm. The loop. It, in which the mainspring works, is inserted in the lower tang,'and is adjusted by turning it in or out, as occasion may require. It also serves the purpose of keeping the mainspring in a central position.

The operation of my improved arm is as follows: The breech-block beinglocked, the carrier down, and the first cartridge-head resting partly upon the carrier, the first backward movement of the handle swings the brace up above the recoil-shoulders, which unlocks the breech -,block. The backward movement of the handle. being continued carries the breechblock back over the hammer and the brace into the recesses c, above the recoil-shoulders,.as.shown in Fig. 8. In this position a cartridge may be passed into the magazine through the charge-openin g, as represented in Fig. 6. As the breech-block retires to the rear the first cartridge follows it back, and when 'the brace strikes the rear end of the carrier both the carrier and cartridge are raised into the receiving-chamber, as shown in Fig.8. Reversing the movement of the handle carries the breech-block forward and the cartridge into the chamber of the barrel. When thebreech-block ceases to move forward the forward movement of the handle being continued swingsthe brace down in front of the recoil-shoulders, and as the brace is depressed it strikes the carrier and carries that down below the mouth of the. magazine, which liberates another cartridge.

IIO

It is obvious that the carrier may be bifurcatcd,,and the dependent portion of the breechbloek and the joint 0, which joins the brace to the breech-block, made to work through the carrier with the same result, as shown in my patent of September 14, 1880; also, that the recoil shoulders may be formed upon guard-strap or upon any other device suita bly supported by the receiver, and serve the same purpose, as shown in my patent of April 26, 1881.
