As the plug must trav-ellongitudnally, the gear 13 onthe same is elongated. The screwplug has a central longitudinal opening, in which is placed a spindle 2, carrying a gas-check M on its inner end and havinga firing-opening 3, and it is provided with means for prevent its rotating. The particular means for locking it to the carrier will be hereinafter described, and, as shown in the present instance, it embodies the cap-plate K and cooperating parts. The plug is also so construotedjand arranged that itis mounted on the carrier, and the carrier practically supports the plug in such a Way that it may rotate and move longitudinally with relation to around or about the spindle 2, although itis not supported by thespindle. The advantage of this construction is apparent to those skilied in the art, as it is wellf known that the fras-check is apt to stick in the breech aftero seat, due. to the lead of the thread..

" In order to reduce the carrier, and at the same time it rotatesplug by rotation, I provide it withaplurality l 1t will be seen that the breechlocking it to the carrier, so as to IOG check suiiicient to-free the gas-check from its into reopening in the carrier i), which opening is snrrounded'hy au annular -lange li, extending into en annuler recess jl; in the rearoi' the'plng. The plug thus turns on and is guido vy the flange li and is mainanni tion While it is permite l r. i toi-th Within the opening in the carrier, n the toothed wheel 13 engages the pinion l2 open e. driving-shaft to which is connected the operating-handle L. The carrier isproviijied h e locking-'ooit e radially, the end D, so supported as to incr lli thereof c tcruf recess u; in e. part of the breech. This my be integre-l with the breech or., es .hor/n, may he a sind l?, secured. to the breech. A spring i8 tends to carry the holt inward, to cause its inner end to .heer upon the face of the teeth of the gear 13, which are out on the projecting portion ot' the screw-plug, and also to cause the inner end. of the loch-bolt 'to enter its locking recess r in the breech Y ng. This projecting portion ol" the ping is pr sided with a epiral caminos -lrhich when the plug is turned oer-.rs on 'the ooit D. This spiral cam-face may he in but, es shown, is formed riphery oi' t. by cutting e, epiral groove, pnieferaiolyof gradueliy-ricreasing "i li toward. the forward ci the teeth of the wheei h'lt being oi' such width er .hete-'een the teeth durhe plug. v"When the lositioini shown in Eig. l, will hee-r 'that nd, across 'the i3, the end d 'or mit it cannot e the rotation intrisa in. `the the locking-- bolt D i of' the cern surface which is farthest of Athe t-plug, and when the ping is tizrnej to wi dran' it from its soc-het in the breech, carrying the toothed.

As the breech-plug is carried toward the breech in closing,r a bevel s on the bolt D metres contact vwith "neveled face 15 on 'the breech, and holt is thereby carried out of the socket o, end the outer end enters the recess w and locks the carrier to the breech. The plug can noviT be turned; but the inner end of the bolt remains in the groove, so that the latter by its screw-like action serves by engaging with the bolt to feed the plug forward in such time and movement that its threads will engage properly'with those of the breech. As shown, when the groove is of grado allydecreasing depth the bolt is gradually forced out of the grooves, and its position in the recess yzu is insured; but this is notabsolutely essential. l

When the parts are in their locked position, the handle L is in the relative position shown in Figs` l and Z-that is, extending later lly toward the hinge l of the carrier. By the peculiar construction and arrangeinent of the teeth on the plug and the pinion turning on a bearing in the carrier engaging the teeth on the plugand having the parts so arranged that the pinion or handle will ro: tete more than a complete rotation, preferably a turn and a'half to completely lock or disengage the. breech-plug, then the handle Will be in a position practically diametrically opposite the position shown in Fig. 2, and thus be in a. position to get the greatest leverage to turn vthe carrier C on its hinge l. To aid in retaining the parts While the carrier is being swung upon its hinge, I provide means for locking the handle in this position, the,

pinion,'operating-handle, and block-carrierr in the position above indicated and retains them there While-.the carrier swings outward or inward Vto open or close the breech mechanisnr.

The rear end of the firing-opening 3 in the spindle 2 is enlarged to receive a primer Y, and about the enlarged end of this opening is fitted the forked end i of an ejector-lever l, pivoted at 19 to the head 10, the spindle and head being prevented from turning, as set forth hereinafter. A slide J is movably iitted in guides at the outer end of the head l0 and isrprovided with a loose pin or ball-j',

fitted into an inclined slot or recessj, whichV ico IIC-

is so arranged that when the slide is lifted by its handle f3 this loose pin or ball will strike the projecting end z' of the ejector-le ver and swing the latter upon its pivot and throw out the primer. By continuing the up# werd motion of the slide until theloose pin or ball has passed beyond the end i' of the ejector-lever the latter will then drop back to its original position and permitof the insertion of 'a new primer Without having to lower the slide J, which would interfere with the ready insertion of a new primer.V Then after the down to cover the primer and hold the same in place for firing the loose pin or bali will be forced upward and outward in the oblique slot until it has passed beyond the end L of the ejectordever. Then continuing the down- Io Ward movement the loose pin or hall will pass by the end t' of the ejector-lever and naturally fall to its lower positionl in the oblique slotin the slide, ready for another' ejection. Vhen the slide is depressed, a shoulder j* rests on the flattened surfaccsj of the head 10, which acts as a stop to hold it in place and in such a position as to securely hold-the primer in place and prevent the -dislodgment of the latter until the iii-ing is 2o eected. This firing may be effected by pulling the friction-wire of the primer or by means of an electric current, and to faeiiit'ate the use of the latter the slide is provided With a properly-insulated plate 20, having a binding-post 22 to receive the end of the electrical conductor 23, it being understood that some other part of the gun is connected to another conductor leading to the electric generator'. The spindle 2 of the breech-plug and gas 3o check, with the head 1G, may be prevented from turning by providing said head 10 with a spline-screw g and with dat side faces g g", bearing against dat bearings supported by the carrier C. Such bearings are best afforded by the inner edges g2 g2 oli' an opening `\.Q `iuamap-plate K, bolted to the rear face of thenarrier C; the head l0 projecting through the opening z, as shown, and the cap-plate being out away at the lower edge to receive 4.o the boss, through which extends the shaft of the pinion l2, connected with the operatinghandle L. This cap-plate not only serves to prevent'the head and parts connected therewith from turning, butl serves as a cap to exclu'de dirtv or other substances from getting into the gear-te`eth or other parte of the mechanism. n..
