This invention relates to repeating breechloading firearms of the type known as the box-magazine gun, and has for its object the production of a simple, reliable and effective arm.

The improvements of the invention consist in the employment of the combined carrier and carrier-spring of great simplicity, a firing-pin and extractor combined with the breech-bolt in the barrel of the arm, and an eective and simple safety-catch mechanism, more fully described and claimed hereinafter, together with minor improvements.

In the drawings, A represents the barrel of the gun, B the wooden stock, and C the guardplate prolonged to form the lower tang c. Combined with this guard-plate and formed integral with it is the trigger-plate c', to which are pivoted at d the hammer D, at c the respectively;

trigger E, and at fV the safety-catch lever F, as more fully described hereinafter. The whole of this metal piece, embracing the guard, lower tang, and part of stock, is hereinafter referred to as the guard-plate, and is connected to the stock by the screw h and horizontal pin h2 and to the barrel by the screw a. of no unusual type, the former having the half-cock notch d and the cock-notch cl2, in which the end of the trigger may engage. A vmain spring R bears on the trigger E at o' and on the antifriction-roller (Z3 carried by the hammer D. y

Below the forward part of the stock B' is a metal strip G, which at the rear end makes a tongue-andfgroove joint with the guard-plate c', and is secured to the stock by the screw b and to the barrel by the screw a passing through the stock and engaging' in a stud a2 dovetailed into a transverse slot in the barrel, as shown in Figs. 1 and 2.

In the forward part of the stock B/ is a chamber H, vforming,with the barrel A, guardplate C and metal strip G, the magazine for the carrier mechanism and reception of the cartridges.

In the metal strip G, forming the bottom of the magazine H, is the elongated vertical opening g, wide enough to admit a cartridge, prolonged at its forward end into a narrow slot g', with the small circular opening g2. In the portion of the guard-plate C forming the rear of the magazine His a recess 7L, having two vertical flanges h and h2, forming grooves h3 and h4, extending from the opening g to the barrel A.

The carrier mechanism within the magazine H consists of the double wire K, looped at an end 7c and united at the lower end It', to which lower end is soldered or otherwise secured a button J with the flange or collar j. The wire K is coiled at k2 about a horizontal pin h3, and is thereby pivoted to the stock B, and adapted to swing in a vertical plane. Normally the flange j of the button J engages with the rear edge g5 of the circulai` opening g2. lVhen the magazine is to be charged with cartridges by pressure, the button J is disengaged from the edge g5 and passes through the opening g2, forcing the The hammer D and trigger E are IOO looped end k of the wire K downward toward and through the opening g, so that a cartridge may be inserted above it into the magazine H. Vhen the magazine is charged, the button .I is pressed to again engage by the iiange j on the edge g5, and the coiled spring exerts a pressure on the cartridges. rIhe looped end of the wire 7c, which forms the carrier of this gun, constantly presses against the cartridges until they are fed successively into the barrel through an opening I. (Described hereinafter.) A modification of this carrier ing I of the barrel.

The butt-end Aof the barrel A, above the magazine H and extending to the rear end, in its internal diameter is `somewhat greater than the bore of the gun, and contains four lateral openings extending longitudinally with it. One of them, I, in the under side of the barrel, placed over the magazine H for the admission of the cartridges, is of oblong shape, and its ends t' and z" are inclined upwardly toward the fore end of the gun. The rear end and adjacent portions of the side Vof the opening I incline sufficiently over the grooves h3 and h4 to detain the head of the cartridge entering from lthe magazine under the pressure of the carrier la, until the fore end 4of the cartridge is raised to`slip into the barrel.

The opening 'O von one `side of the barrel, adapted in size and shape for the passage of the Icartridge when ejected, is prolonged toward the fore-'end of the gun in a narrowslot o, the forward end vof which is inclined inwardly to the rear -of the gun. 'On the `same side and same horizontal plane the narrow Vslot o extends to the butt-end of the barrel, havin-g its fore-end beveled inwardly 'and forward'ly.

The narrow rectangular slot Q, formed in the side of the barrel opposite the opening'O, has its -re'ar end q inclined inwardly to the rear to act as -a recoil-abutment.

VVithi-n the portion 'of the barrel enlarged internally 'are the breech-bolt L, firing-pin M, and vextractor N. The breech-bolt L, of cylindrical form, is `divided horizontally into two portions, united "at their forward 'ends by the block Z. It receives between its two portions the lfiring-.pin M, loosely pivoted by the pin Z mounted in the breech-bolt'and'extending rearwardly beyond said breech-bolt. A

shoulder mof the firing-.pin is constructed to extractor N is constructed integral with the firing-pin M at the point n to form a springcatch extending beyond the breech-bolt L in the slot 0, and notched internally at n2 to engage with the rim of the cartridge.

The point m2 of the firing-pin M extends forwardly beyond the breech-bolt L, through the small opening Z2 in the end of said breechbolt, and is adapted to impinge upon the rim of the cartridge when the rear end of the firing-pin is struck by the hammer D.

The firing-pin and breech-bolt herein described lare constructed for rim-fire, but by slight alteration may be adapted for central lire. Y

Parallel to the barrel and on the side of the slot Q extends the action-handle S-a narrow strip of metal--its forward end s constructed to partially surround thebarrel, the whole capable `of longitudinal movement. The rectangular slot s', located opposite the slot Q, receives the extension m of the firingpin, which projects through the slot Q and is bound to said action-handle by the pin m3, as shown in Figs. l and 3.

In the extraction of a spent cartridge, the

action handle being drawn rearward, by

means of the extension m forces the firingpin rearward with it. The loose bearing of the firing-pin M on the pin Z allows sufficient play for the release of the shoulder m from the recoil-abutment q before the rearward action is transmitted to the breech-bolt L. Continued rearward movement of the actionhandle withdraws the breech-bolt, firing-pin, and "extractor connected thereto, (which engages the rim of the cartridge,) thereby pulling rearward the 'cartridge until its rim comes in 'contact with a notch 'a3 l(or pin) in the barrel. The spring-catch of the extractor forces the cartridge in contact with the notch a3 and draws lit about, ej'ectin'g it through the opening 0. The breech-bolt L presses against the hammer D, forcing it backward until it is fully cocked. While the breech-bolt and appended parts are thus withdrawn, the carrier fle presses into the barrel a new cartridge, and the forward 'movement of the actionhandle acting on the breech-bolt forces the -cartridge into its chamber in the barrel, as shown in Fig. 3.

A feature in this invention is the safetycatch mechanism, to prevent the premature discharge of the lgun before the breech-bolt is restored by the action-handle to its nor- -mal position in the barrel, and the shoulder 'm engaged with the recoil-abutment q. This mechanism consists of a lever F, .pivoted at fin the guard-plate C, having the elbow f', and lan arm f2, forming at f3 an angle vin a vertical plane 'at right angles to that of the two arms y'of the lever. A notch s2 in the acabut-ment.

IIO

ver -presses a spring w in a recessWV in the guardplate C. The engagement of the arm f2 with the action-handle S overcomes the tension of the spring w, until said arm f2 is released by the rearward movement of the action-handle, when the spring w forces the arm f4 of the lever to engage with the notch d4 in the hammer D, when said hammer is fully cocked.

Until the breech-bolt L is withdrawn sufficiently to fullcock the hammer D a cartridge cannot be pressed by the carrier lainto the barrel, and it is apparent that after the hammer has been full-cocked it will be engaged by the lever F and prevented from forward movement until the action-handle S is again drawn forward, and the breech-bolt L by means of the firing-pin M locked with the recoil-abutment.

The details of construction of this gun may be varied somewhat without departing from the spirit of the invention, and

What I claim isl. In a repeating breech loading rearm, the combination of the stock thereof, with a magazine, of a coiled spring pivoted in said magazine to swing in a vertical plane, the upper end of which is looped to form a carrier, the lower secured to a iianged button; and an opening leading into said magazine for the passage through it of the ends of said coiled spring and button, and adapted to engage said iianged button for holding said spring in tension, substantially as described.

2. In a repeating breech loading iirearm, the combination with the stock thereof of the barrel having a passage in the under side, a box :magazine in the stock communicating with said passage, constructed with an opening in the bottom adapted to receive cartridges, said magazine being so constructed that the cartridges may be fed vertically upward from said bottom opening in said magazine into said under passage in thebarrel, and a lateral opening in the barrel formed for the ejection of cartridges, substantially as described.

3. In a breech loading iirearm the combination in the barrel thereof, with a cylindrical breech bolt divided horizontally into two parts united at their forward ends, of a combined part comprising the firing pin and extractor between the portions of said breech bolt and pivoted thereto, having a shoulder adapted to lock with a recoil abutment formed in the barrel, substantially as described.

4:. In a breech loading firearm, in the barrel thereof, la cylindrical breech bolt capable of longitudinal motion within the barrel, divided horizontally in two portions united at their forward ends, substantially as described.

5. In a breech loading irearm, the combination with the barrel thereof, having a lateral slot, with an action handle capable of longitudinal motion, of a breech lbolt within vthe barrel, and a combined part comprising the iiring pin and extractor, pivoted to said breech bolt and connected through said lateral slot to the action handle, said combined part and breech bolt being capable of longi-V tudinal motion and operated by said action handle, substantially as described.

6. In a breech loading firearm, the combination with the barrel, of a guard plate in which are pivoted the hammer and an angle lever, a spring constructed to press against said lever to throw an arm of said lever into engagement with anotch in the hammer when full cocked, a breech bolt and firing pin within the barrel, adapted to lock with a recoil abutment in the barrel when fully closed, andan action handle connected with said firing pin and breech bolt and notched to engage with an arm of said angle lever to overcome the pressure of said spring when the parts within the barrel are locked with said recoil brace, substantially as described.

In witness whereof I have hereunto set my hand this 18th day of February, A. D. 1895.
