SPECIFICATION forming para of Ltrers Patent Ne. 366,565, dated .Iuiy 12, ias-7.

Application tiled November 2i, 1885; Serial No. 1784,10?. (No model.)

To all whom, it may concern:`

Be it known that 'LANDREw BURGEss, a citizen ofthe United States, residing at Owego, in the county of Tioga-and State of New York, have invented certain lnew and useful I1n provements in MagazineFire-Armsof which" the followingis a specification, referencebeing had therein to the accompanying drawings.A

-This invention relatesfto magazine `and breech-loading fire-arms; and it consists in improvements `on locking, unlocking," and moving the breechv mechanism, and 'various combinations of parts for the object ofeasy .or semiautomatic and safe operation, as here inafter more fully set forth.

`Figurel is a longitudinal side elevation in vsection of an arm-construetedwith these iini provements.

y Fig. 2 is a plan viewof the top. Fig. 8 isa reduced section-of the butt. Fig. shows the operative'parts of Fig. l in an open position. Fig. 5 shows thelhammer in section; and-Fig. 6 shows in detail the relation of the top of the lever R', the unlocking de*` vice workedthereby to start open the breech, and other details. v-

- A metaframe; nthebreeoh-bou; B, the

barrel; M, the magazine; C, the carrier; l), the locking-brace; S, the slidinghandle; R, the operating1od; F,the tiring-pin; H,the hammer, 4

T', the trigger; R', the starting-lever; R", its operating-rod, and D, its lockingdog;

This arm is operated by a sliding handle,S,

which is counectedto the bolt by its rod R and pinf, which couples it to the brace. The

cr0sspinf, traveling ina longitudinal slot ink the bolt, projects into .an oblique slot in the lockingblock, yso l ,thatl the, backward movement of the handle S moves back-the cross- -pin f, which, first bearingagainst lthe side wall of the kslot of brace D, turns it inward to unlock it, and then, bearing backward against the,rear wall of said slot, forces it and thereby v the bolt backward -to open the breech, and the forward movement of the handle S closes the breechby reversing the above operation.`

The handle S consists of asleeve encircling the barrel, magazine, l, or asection, as in Fig. 2,'to curve around the lower part of the body of the gun, and a supporting-bolt, as S', is passed through the sidesof the handle, to stiften it and prevent its sides from bending inward against the fore and fore-arm, as in Fig.`

`bolt S to travel in and to guide said bolt and handle in its movement back and-forth. The

bolt S' may also serve, as in Fig. 2, to attach Vthe forward end ofthe rod R to the sliding handle.'

The rod R extends backward to be guided in a groove in the side of the frame, and a slot.A

4in the rear part of the frame allows the pin f` ofthe operatingrod' to reciprocate therein and move the brace and breech bolt, as already described,and apin, 'of rod R, projecting inward through a slot in theframeand bolt, engages the scar T', when the operatingpin of rod R reaches, the horizontal part of the slot of the brace and shall have' fully locked the breech, as in Fig. 1, to turn scar T from the position'` shown in Figl 4 (where it holds the hammer cocked) to therebyl release the `hammer and discharge the gun by the conti n uation `of the same movement of the rod R which closes the breech. ,i Y

The sear T' is hung in the frame and pressed by` a spring to engage a notch in the hammer when" in a cocked position: f

A'notherprojection, as r', ofthe operatingrod R, enters the eXtreme rear part `of the frame and bolt to projeetinto the path of movement Vof the upper arm of lever R,vwhieh is pivoted in the frame, so that a forward pressure on the flower arm of said lever R' forces back its up- `per Aarm against the pin r' to start back the `operatingrod and thereby the breech-bolt,

and such pressure orforce may be applied by the hand to the lower projecting end of lever R', or automatically, as by the rod R", which extends backward, and is provided with a weightto resist the recoil of the gun, or projects to the butt-plate, so as to be resisted by the shoulder ofthe operator and its own weight against the recoil, as shown in Fig.4 8, and I lock the rod R" against its forward movement in the gun'by a dog, as D,which, engaging the rod R", as in Fig. k1, locks it in its rearward .position but said arm has a projection, asW', by which it can be turned at will to unlock the rod, and I here show said projection as a weight whose inertia, resisting 4the recoil of the Ico gun, serves to turn thedog out of its notchin A the rod R, and as the movement necessary therefor isv very slight (and the weight is small in proportion to that which causes the rod to move forward) it results that the rod becomes unlocked by the first part of the recoil movement and its continuance causes the lever R to operate by force of its recoi-l against rod R" to start open the breech and the shell from its seat in the chamber of the barrel.

A dog, d, is pivotedin the breech-brace D, and has a spring to turn it into engagement with the ledge z in the bolt when the brace is in its locked position to hold it there; but said dog has a thumb-piece projecting at the top vof the bolt, so it canbe moved at will to unlock the brace, and, also, the firing-pin has a shonl` der, 2, which in its movement forward, as by being struck forward by the hammer, engages the lower arm of the dog to force it out of engagement, so that the brace is then free to be movedby the Arod R, as aforesaid. It is'obvions that the locking of the brace by the dog d thereby locks the rod R andy the operatinghandle forward. I

The hammer is provided with a long swinging piece or fly, as 7l, which in its upward po-v sition, as in Figs. I and 5, receives engagement of the bolt when movedl rearward to cock the hammer; but a sliding thumb-piece, h, is arrangedin a slot in the hammer to carry awedge or block downward against the rear of fly t to block it forward, asin Fig. 4 and broken lines in Fig. 5, so that its point remains below the line of engagement ofthe bolt aforesaid, and

the bolt may then be moved back and forth over the nose of the hammer without cocking y it and without the expense of power usually applied for that purpose, and the gun may be cocked by the trigger as is usual in the socalled self-cooking arms. I here hang to the trigger the sear-piece h', with a spring to turn its upper arm forward to' engage the notch in the hammer, as shown in Fig. 4, and the lower arm of the scar-piece comes in contact with the guard-strap when the trigger has moved the hammer to full-cock, so that the scar-piece is then turned to release ythe hammer and a spring bears the trigger back (when released) to its normal position. lower part of lever R is in its extreme forward position, as in Fig. 4, the trigger cannot be pulled Yback far enough to release the hammer.

As a substantial equivalent of the weight W', the Weight NV may slide on the rod R and carry an incline, as shown in dotted lines, to release the dog D.

A stop, f, is pivoted in the guardstrap, so that when it is turned one side, as shown in Fig. 1, it allows the trigger to turn forward, so that its scar-piece may be operated by v the trigger in the self-cockin`g manner; but

when the trigger is pulled nearly back and the stop tis turned forward of it, as in Fig. 4, to hold the trigger back, it then has but little movement, and the sear is held by it in posi-j tion, as shown, to catch and hold the hammer lVhenthe at full-cock, (whenever it shall be turned back by the bolt or hand,) and the trigger has to be pulled but slightly back to release the hammer, as in the ordinary manner in arms that are not selfcooking.

ObviousY changes in location of parts and equivalents of construction are intended to be covered by the claims.

I claim- I. vIn a magazine fire-arm, a sliding handle curved around the fore-arm in front'of the frame andprovided with a supporting-bolt to hold the-sides' of the handle apart, the slot S between the bores of the barrel and magazine for said bolt to traverse, and a reciprocating rod connected to the handle and breech-piece,

by which reciprocating movement ofthe handle opens and closes the breech, all in combination, substantially as specified.

2. In a breech mechanism ofa magazinegun,

having reciprocating movement to open and close the breech, the sear-pawl T', pivoted in the frame above the axis of the hammer, and having an arm extending rearwardinto engagement with a notch in the hammer when vsaid hammer is in cocked position, and a projection above its pivot,which is engaged by a shoulder on the breech mechanism inthe final movement of the breech to disengage said searpawl from the hammer, and 'a trigger which operates on the hammer independently of the breech-closing mechanism, all combined substa-ntiall y as described.

3. In combination with abreech-loading gun having the usual operating-handle and 'connections therefrom forv operating the breech mechanism,a starting-rod, in combination with `a locking-piece to hold said rod out of operative engagement, a connection to the lockingpiece to disengage it from the rod, and a breech -piece and means of engagement between the breech-piece and rod, by which the forward movement of said rod assists to open the breech, substantially as specied.

4. In a breechloading fire-arm, a vibrating hammer, a sear, as T, hung in the frame in position to engage a notch in the hammer and hold it at full-cock, in combination with a reciprocating rod which serves to connect the operating-handle with the breech mechanism and its projection, as t', to engage and release the sear in the last part of the movement of said rod in closing the breech, substantially as specified. 5. In combination with the breech mechanism of a breech-loading nre-arm having the usual operating-handle and breechconnec tions, a leverpivoted in the frame, Whose upper end makes connection with the reciprocating breech-bolt,- and'means of propulsion below its pivot, substantially as described, by which the lower end of said lever may be forced forward to rotate backward its upper end and thereby start back the bolt.

6. In a breech-loading fire-arm, a reciprocating rod operated by a sliding handle and -IOO IIO

\ thc stock, said piece provided with a lever hung in the frame in position connected with the breech mechanism to operate it, in combination withan auxiliary lever hung in the frame in position to engage said rod to start it, and thereby the breech-piece and cartridge shcll, said lever being disengaged as the breech-piece moves backward, and a projection of said leverextendingoutside the body of the gun, by which it may be operated by a movement inthe 'opposite direction `to that of the sliding handle to start open the breech, substantially as described.

7. In a `breech-loading fire-arm, a startingto, engage the operative mechanism of the gun, and, in combination therewith, an operating-piece in locking device to hold it from moving with the lever, and means for releasing the said operatingpiece, substantially as described.
