SPECIFICATION forming part of LettersPatent No. 453,303, dated June 2, 1891.

Application filed May 24, 1890. Serial No. 853,284. (No model.)

To all whom it may concern.-

Be it known that I, KOSTA R. MILOVANO- VITCH-KOKA, colonel and military attach of the King of Servia, subject of the King of Servia,and residing at Vienna, in the Province of Lower Austria, in the Empire of Austria- Hungary, have invented certain new and useful Improvements in Repeating-Rifles; and I dohereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make'and use the same, reference being had to the accompany- 1ng drawings, and to letters of reference marked thereon, which form a part of this specification.

Referring to the drawings, Figure l is a longitudinal sectional elevation of so much of a breech-loading gun embodying my invention as will be necessary to illustrate the same. Fig. 2 is a top plan View, and Fig. 3 a side elevation with part of the receiver broken away. Fig. 4 is a longitudinal axial sectional elevation of the breech-bolt; and Figs. 5 and 6 are top plan views, the handle or actuating portion thereof--being shown drawn out in Fig. 6. Fig. 7 is a side elevation, and Fig. 8 a cross-section on line m tr of Fig. '7, of the breech-bolt proper. Fig. 9 shows the breech-bolt head byan end and an under side. view, respectively. Fig. 10 shows the handle. or actuating piece of the breech-bolt in side elevation and cross-section, respectively, the latter being taken on or about on the line y y indicated in said side elevation. Fig.11 shows in end view and side elevation that piece of the breech-bolt to-which the firing-pin is connected and that serves to set the said pin to full or half cock. Fig. 12 shows the firing-pin by an end view and apart thereof in side elevation. Fig. 13 is a sectional side elevation of the receiver and magazine and a portion of the gunstoc'k. Figs. 14, 15, and 16 are cross-sections of the magazine and receiver, illustrating the cartridge-locking device in various positions. Fig. 17 is a longitudinal section of the magazine-case, and Fig. 18 is a top plan view of the magazine. Figs. 19, 20, and 21 are detail perspective views of parts of the magazine. Fig. 22 is a perspective view of the handlepiece A of the. gun.

The invention relates to that class of breechloading fire-arms in which the breechbolt has a longitudinal and partly-rotary movement imparted to it by a pull in a rectilinear direction and known as the straight-pull breech action; and it has for its object to simplify the construction of thebreech action and increase thestrength thereof and to combine with the gun a magazine depending therefrom and opening into the receiver, the cartridges being fed thereto in a straight vertical line by a feed-spring and follower.

The further object of my invention is to provide the magazine with means for holding the cartridges from being moved into the receiver when the breech-bolt is drawn back and with means for moving the cartridge holder or check out of the way and locking the same in that position to adapt the gun for use as a single-loader; also, with means for compressing the feed-spring and forlocking the same and the follower against operation for the purpose of facilitating the introduction of the cartridges into the magazine.

To these ends the invention consists in the construction .of the breech mechanism, in the combination of the parts thereof, and in the construction of the magazine, as will now be fully described, reference being had to the above-described drawings, in which like letters indicate like parts wherever such may occur in the figures thereof.

A, Fig. 7, is the breech-bolt proper, and is provided with the longitudinal lockingrib (t and at its rear end with a helical or spiral groove a, that is engaged by a correspondingly-formedlextension a on the handle-piece A, Fig. 10, said piece carrying the handle a having the locking-shoulder 0 The handlepiece A is further providedwit-h a prismshaped guide-rib a, that moves in a cone sponding groove 1), Figs. 1 and 2, formedin the receiver B, so as to lock said handle-piece against rotation in said receiver when moved to or fro therein in closing or opening the breech and to impart to the breech-bolt A a partial revolution when the spiral extension 0, moves in the spiral groove a of the breechbolt. When these parts are in the position shown in Fig. 6, the breech-bolt can be introduced into the receiver, a shoulder a", Figs. 10 and 22, of the spiral extension (6 of the vi I 453,303

handle-piece A hearing against the rear end of the breech-bolt A, so that the latter can be pushed forward to close the breech. By conwill move in the spiral groove a of the breechbolt A and impart to the same a partial rotation toward the right, whereby the lockingrib a is caused to enter a longitudinal recess in the side of said receiver B, the breech-bolt assuming the position shown in Figs. 1, 2, and 5.

In the bore of the handle-piece A is fitted a piece A Fig. 11, which constitutes the cock of the firing mechanism and is provided with a rib 0. in which are formed the half and full cock notches a a respectively, and'said piece has a milled flange (13 for manipulating the same.

The breech-bolt A, the handle-piece A, and the cock A are connected together by means of the firing-pin at, whose rear endis screwed into the piece A said firing-pin having a collar or annular flange a. near its front end,

. that forms an abutment for one end of the usual coiled spring a on said pin; the other.

end of which abuts against the rear wall of the enlarged portion of the bore of the breechbolt, as shown in Fig. 4.

To the front end of the breech-bolt is secured a. head, hereinafter referred to as the bolt-head A, Fig. 9, which has an attenuated extension or shank a, in which is formed a diametral slot or recess a, into which fit the locking-lugs 0. Fig. 12, of the firing-pin a and said extension a of the bolt-head fits I cockA to or unscrewing it from the firingpin a The bolt-head A is locked to the breech-bolt by means of a screw a, that enters a recess in the shank a of said bolt-head, the said screw serving also to connect the stop-disk'a to the locking-rib a of said bolt:

The bolt-head shank a and the bolt-head A have a longitudinal peripheral groove a for the reception of the shank of the shellextractor a", which is thus detachably connected with the breech-bolt and securely locked thereto by-the bolt-head, the extractor.

being suitably bent, as shown, to conform to the difference in the planes of the groove a in the bolt-head and its shank, as plainly shown in Fig. 4. The bolt and bolt-heads are further locked together by a projection a on said head engaging a recess a, formed in the end of the locking-rib a, that projects beyond said breech-bolt, as shown in Figs. 5 and 6.

At its outer end the bolt-head A has two radial lockin g l u gs a, adapted to engage corresponding recesses b' in the forward end of the receiver B, Figs. 1 and 2, thus adding very materially to the strength of the breech mechanism and its power to resist the recoil of the explosive charge in firing.

I have hereinbefore stated that. when the breech-bolt and its component parts are in the position shown in Fig. 6 said breech-bolt may be introduced into the chamber provided therefor in the receiver. It follows that by moving said bolt into the position shown theymay be removed from the receiver, andfrom the description of the means for connecting the parts it will be readily seen that they can be dismembered or disconnected with great facility. This is done by first unscrewing the cock A from the end of the firing-pin a then loosening the screw (r snfiicient-ly to permit the withdrawal of the bolt-head A when the firing-pin and its spring may also be withdrawn, and as the intermediate piece A, that actuates the breech-bolt, is connected thereto by the firing-pin and the cock A said piece can be detached immediately after the piece A has.been unscrewed from the firingpin. The removal of the bolt-head A also permits the'removal of the shell-extractor a",

as will be readily understood.

' The parts A A A A that constitute the breech-bolt, are of such construction as to present no weak points, so that the breech-bolt is substantially as strong as if it were made in one piece, while the locking devices a. and

a provided lock it firmly to the receiver.

As the breech-bolt is being moved forward to close the breech, the full-cock notch of in the rib a of the cock A will engage the sear a and prevent the cock A and the firing-pin from .advancing with the breech-bolt, thus bringing the spring a under tension tothrow the pin forward when pressure is applied to the trigger a, to which the searis fulcrumed orpivoted. The sear and trigger are returned into'their normal positioniby the sear-spring a, Fig. 1, and as shown in said Fig. l the triggerhas a lever-arm a, that bears on the under side of the rear tang 12 of the receiver to provide the necessary leverage to depress the sear a.

The gun may be fired by the forwardniovement" of the breech-bolt when this is done with sufficient force to explode the cartridgeprimer by locking the sear out of the path of the cock A To this end I provide a'locking lever or latch a, Fig. 1, that has a notch in its forward end adapted to engage a corresponding shoulder of on the. trigger, said latch being pivoted to the trigger guardtas shown.

It has hereinbefore been stated that the cock A has a milled flange or rib 0. for the purpose of nianipulating said cock. It will readily be seen that the cockmay be drawn out for the purpose of setting the same for firing after the breech is closed or for releasing the said cock from the sear or setting as a whole is very short as compared with the secured to the receiver, as shown in Fig. 13.

breech-bolts-in use in this class of fire-arms, and that it is devoid of a groove in that portion which carries the locking-rib, as is usual, so that those parts which are subjected to the greatest strain are in no manner weakened. On withdrawing the-breech-bolt A to open the breech the spiral extension of the actuat ing-piece ,A operates in the corresponding groove 0. of the breech-bolt proper and imparts to said bolt a partial rotation from right to left, thereby disengaging the rib a and the radial locking shoulders a from their re-' spective recesses, when the breech-bolt is free to move back to its full extent. This backward movement of the breech-bolt is limited by an abutment 11 Fig. 1, on the receiver, which is in the path of the stop-disk a" and arrests the further backward movement of the bolt.

The gun,as described, may be used as a single-loader, or it may be used as a' rapidfiring or magazinegun, to which end the receiver has in its bottom in front of the trigger-guard a slot of such form and dimension as to afiord a ready passage to a cartridge inserted from below, a vertical magazine being employed to receive a number of cartridges and feeding devices combined therewith to feed the cartridges one after another to the slot in the receiver.

The magazine 0,-Figs. 1 and 13 to 18, inclusive, is substantially of parallelogramm atic form, the forward vertical wall thereof being conical or having the sha'peof a bullet, as shown in Fig. 17. Around its upper edge is formed a flange 0 by means of which it is The bottom 0 of the magazineC is detachably connected with the casing, said bottom having at its front end a lug or lugs 0-, that take into a suitable slot or slots in the forward end wall of said casing, (see Figs. 13 and 17,) while at its rear end said bottom carries an exteriorly-threaded sleeve 0 Fig. 1, that is screwed into a nearly-cylindrical recess 0 Fig. 17, formed in the rear wall of' the magazine-casing, said sleeve serving also as a bearing for the lower end of a rod 0", provided at its upper end with a wedge-shaped block 0 hereinafter referred to as the spreader-wedge,

and for purposes that will presently be ex plained. p

The cartridges may be'supplied't o the magazine one by one, or a number of them in the form of a charge may be introduced by the 'aid of cartridge-holders, each holder carrying a number of cartridges suflicicnt to fill the magazine. On the other hand, the feeding devices for the cartridges may be locked against operation and the gun used as a single-loader, the cartridges being introduced into the receiver from above after thebroechbolt has been moved back to uncover the breech, as' shown in Fig; 3.

The feeding devices for feeding the cartridges to the receiver B consist, as usual, of a feed-springc, to the free end of which is secured a follower 0 (See Figs. 1, 3, and 18.)

In order to prevent the cartridges leaving the magazine under the stress of the feedspring 0 when the receiver is open, I provide a stop 0, Fig. 20, consisting of a plate 0 that has two L-shaped spring-arm's 0 .0 and to the back of said plate is secured a sleeve 0" for the passage of the screw-rod 0 Fig. 1, that connects therear' end of the magazine bottom a to the casing, as hereinabove set forth, and that serves as a guide to the springstop 0', which is movable vertically on the rod 0 As shown in dotted lines in Fig. 1 and in full lines in Fig. 3, thearms c extend forward along the shell of the upper cartridge, and the distance between them is such as to allow the rim of the shell to project slightly into the receiver, as shown in Fig. 3. The elastic or spring arms are comparatively short, so that the forward end of the cartridges will is moved forward its head A will engage the projecting shellrim and carry the cartridge along, which cartridge will be pushed fully into the receiver as soon as its rim has passed the end of' the spring-arms c of the stop C, as will be readily understood.

C is secured a plate whose ends project be yond the opposite sides of said plate 0 and to said ends are secured milled disks 0 that lie outside of the magazine-case, the projecting ends 0 of the plate lying in a vertical slot 0, on the rear wall of which'is formed a stop-shoulder 0 as more plainly shown in Fig. 13.

It willrbe readily seen that when the stop C is pulled down against the stress of the feed-spring and the projecting ends 0 moved under the shoulder a the cartridges will be locked against upward movement under the stress of said feed-spring, so that the gun can be used as a single-loader. By simply shoulder a the feed-spring will at once carry the parts into their normal position, the upthe end of the slot 0, and is locked against downward movement by the locking-shoulder e As shown in Fig. 20, the L-shaped springvarms 0" c of the stop 0 are bent toward each other or inwardly in such manner as to form a V-shaped space above the bend of the arms; When the stop is in'its normal position, this bend lies immediately below the spreaderwedge 0 hereiubefore referred to. By moving the spreader-wedge downward between said spring-arms they will be spread apart be tilted upward, their bullet ends projecting fairly into the receiver. As the. breech-bolt At the lower end of the plate a of the stop ward'movement of the stop being limited bymoving the stop from under the lockingdown the draw-bar the follower will also and lie along the lateral edges of the slot in the receiver, (see Fig., 14,) thus admitting free passage to the cartridges. The object of these devices is to provide a means whereby the magazine may be emptied by simply spread- ;ing the arms of the stop 0' and uncovering the receiver, when all the cartridges will be ejected by the feed-spring.

In order to" return the spreader-wedge 0 into its normal position, a coiled spring'c is mounted on the rod 0 Figs. 1, 3, and21, between the sleeve 0 of the stop 0' and the wedge 0 e The rod 0 and wedge e are moved down wardly by the following devices: A camor eccentric provided with a thumb-piece c is arranged to revolve in. the sleeve or tubular nut 0 hereinbefore referred to, said eccentric having an inclined face 0 in contact with the bottom of the magazine, and to said eccentric is pivoted the rod 0 that carries the spreaderwedge 0 If the cam is turned to the povsition shown in dotted lines in Fig. 17, the inclined surface will move under the magazine,

drawing the rod 0 down to spread the arms of the stop 0 as will be readily understood.

In the description of the construction of the parts of the breech-bolt and their interconnection through the medium of the firingpin and its spring I provide an elastic connection between these parts, whereby the cock A and. the handle-piece A may have an independent motion, the head A 'being made removable for the purpose of having access to the chamber that contains the spring which actuates the firing-pin.

As shown in Figs. 3 and 13, the magazine is provided in its opposite sides with a recess 0 at the base of which is formed a semicircular slot or opening 0 Fig. 13, In said recesses is fitted a yoke or U -shaped actuating or draw bar 0 Fig. 19, the vertical spring-arms c of which are slotted 'for the sake of lightness and for the purpose of giving them a greater of a quarter of a sphere.

;' curedto the feed-spring 0 has a lug on each side, whichtakes into the upper end of v elasticity. At their upper ends said arms are provided on opposite sides of the slot with a lug 0 the form of which is substantially thatv The follower c sethe slot of the spring-arms 0 of the drawbar At its lower end the draw-bar G which straddles the bottom of the magazine,

has on each side a milled button 0 that serve as thumb-pieces or hand-holds. By pulling be drawn down, thereby compressing the feedspring 0 and as the lugs e reach the semi- .cylindrical slot 0 atthe. bottom of the recess the spring-arms will expand or spread, owing to their elasticity, the lu s 0 en 'a dn said I b b b slot, thus locking the feed-spring against operation and into its compressed position. I

The object of the described arrangement is to admit of the introduction of a charge of cartridges through the receiver without interference by the feed-spring, so that the magazine may be readily replenished.

In the introduction of the cartridges it is not necessary that the looking or retaining arms 0 c of the stop 0' be spread. These arms being, as stated, more or less elastic will yield to pressure from above and spread, so as to admit of the free passage of the cartridges.

In the description of the magazine 0, I have stated that the bottom thereof is detachably.v connected with such magazine, and as the feed-spring c is secured to said bottom it is obvious that thesaid spring can be readily removed when this becomes necessary for in the receiver for locking the handle-piece against rotation, said extension. having a shoulder 0.", adapted to engage the rear face of the breech-bolt, as and for the purpose set forth. v
