The carrier-lever G is actuated by the fllllb ing of the lever N P, as in the turning of the trigger-guard lever in the \Vinchester arm, whereby after the breeclrpiece is opened the carrier rises, and after the breech-piece is i from the shoulder.

closed the carrier is dropped. This connection of the carrier-lever with the trigger-guard lcver of the Winchester arm is too well known to require detailed description in this specification.

To retract the firing-pin before the breechpiece commences its rear movement, and hold it so retracted until the breech-piece is completely closed, 1 form a cam-like projection, on the top of the strut I, which, as the strutrises, enters through a slot in the breech-piece into a corresponding cavity, in, in the firingpin, as seen in Fig. 4, which forces the firingpin to the rear and holds it in that position until the strut is dropped, as before described, into its locking position. Then the firing-pin is free for the action ofthe hammer.

The operator holding the gun at his shoulder, with his left hand upon theslidc S, in the usual manner of holding a gun, after the first discharge he has only to force the slide S forward, as seen in Fig. 2, without taking the gun Such forward movement draws back thebreech-piece, and with it the ray ploded shell,whichis engaged by the extractorhook a, the same as in the Vinchester arm. throws up the carrier, ejects the shell, pre sents a new cartridge, and then, still holding the slide S, draws it rearward to bring the parts back to their normal position, as seen in Fig. 1, which forces a new cartridge into the barrel and returns the carrier, the parts oper atirg, as before stated, substantially as in the Winchester arm. This movement of the slide, it willbe observed, is the natural movement of the left hand in the act of presenting the arm to the shoulder and taking it therefrom-- that is, as the arm is brought up to the shoulder the left hand naturally comes baeluvard' beneath the gun, in which movement the parts are brought to their operating condition, and then after discharge the natural movement of the left hand is forward, and which natural movement opens thc breech-piece, discharges the exploded shcll, and presents a new cartridge. This arrangement, whereby the natural movement of the hand operates the mechanism of the arm, is a great advantage over the reverse action, as in other arms which are operated by a slide beneath the barrel, as in such arrangement the forward movement of the arm at the time of preparing to fire is an unnatural one, and the rear movement of the hand after firing to open the parts is equally unnatural; but should it ie desirable to arrange the: slide so as to thus move forward in closing the breech-piece, and rearward in opening it, the connection T from the slide S may be made in the form of a bar, representedjn Fig. 3,) passing rearward through the receiver, as in dicated in Figs. 6 and 7 and connected directly to the stud (l on the arm L. The movement of the breech-piece will then be the same as before; but inasmuch as the hub of the lever, N 1? cannot then be utilized to operate the can. rier-lever G a modification of that lever will be necessary. This modification is seen in Figs. 3 and 4, and is as follows: At the rear end of the carrier-lever G an arm, 0, extends upward and in the path of a stud, g, on the arm L, in its rear movement, and so that as the slide N approaches its extreme rear movement the arm Lwill come against the arm 0 and turn the lever G upward, raising the carrier, as seen in Fig. 41, substantially as before. The lever is caught in this up position by a spring-dog, R, entering a notcluf, in the lever below its pivot u, this dog being sufficient to retain the lever in its up position while the brcech-piece is being moved forward and un til power be applied to turn the lever. As the breech picce approaches its forward movement the strut .l. is depressed, as before described, and in such depression or downward movement of the strutl it-strikcs an. arm, 7:. forward of the pivot a of the lever G, and thereby forces the lever G downward, taking with it the carrier, and in this down position the lever (l is caught by the spring-dog R falling into a notch, 1 on the hub of the lever. ln this modification I have represented the pivot on which the lever G- is hung a little. higher up and to the rear of the pivotof the lever N I in the first description, and this is desirable in order to the best action of. the lever thus modified.

Instead of employing the verticallyreciprocating carrier, which 1 prefer, a vibrating carricr may be hung at the rear upon the pivot a, substantially as is the lever G, to receive the cartridge and present it to a position in front of the open breech-piece, said vibrating carrier provided with projections corresponding to the projections c h, whereby the last part of the rear movement of the breeclrpiece will raise the carrier, and-the last part of the forward movement of the breech -picce will drop the carrier.

The arrangement of the slide S so as to be forced inward in opening the breech-piece and rearward in closing may be applied to arms having other operative mechanismas, for illust 'ation, many of the arms in which the mechanism is operated by a trigger-gr 1rd b ver may have a connection from tha lever to the slide S corresponding to the connectiop 'l use)" a in the-armhereinbefore described, and wherement, a lever hung by the arm will operate bythe movement of the slide forward and rearward as it before was operated by the forward and rearward move-' ment of the trigger-guard lever. Q I therefore do not wish to be understood as limiting thisarrangement of the slide to the particular mecl'i-v anism of the arm describedand instead of employing'the lever L I theentire mechanism of TO the Winchester arm'may be employed, the con nectiorrfrom \the slide" being made 'directlyt'o the trigger-guard lever below its pivot.

I claim-- I 1 1. In amagazine fire-arm, the combination I 5' of the breech pieceand thecarrier, with intermediatemechanism, substantially such as de scribed, whereby asthe breech-pieceis opened the previously-fired -cartridgeis retracted and a new cartridge transferredfrom the magazine to a position forinsertion into thebarrel, witha slide arranged beneath the barrel, free for reciprocating movement in line with the barrel,

and a connection between said slide, with; a

meohanism'which operates the breech-piece and carrier, wherebythe forward movementof said slide opens the breech-piecaan'd the return or rear movement of said slide closes the breech-piece and brings the parts to the firing condition, substantially as described. 3o 2.

moved in the opposite-direction will force said 'breehpiece forward through the carrier to transfer the cartridge so presented to the barrel and drop the carrier, substantially as described.
