50 'rr/ZIE zz/bom, it may; concern:

Be it known that I, ANDREW BUR 1.Ess,of Owego, .county of Tioga, State of Xew York, have invented certain new and useful Improvements in Magazine Fire-Arms, of wh ich the following is a specification.

My invention relates to breech-loading and magazine-guns, and has for its object simplification of construction, increase in strength, and ease and certainty of manipulation.

This invention consists of various improvements on the well-known Iinchester arm, together with other combinations and arrangements of parts, hereinafter more fully set forth and claimed.

In the annexed drawings similar letters indicate corresponding parts.

Figure l. represents a longitudinal vertical section of this arm. Fig. 2 is a plan section of part of the frame, showing the method of attaching thereto the link and the position of the bolt. Fig. 3 is a sectional view of the arin in its open position. Fig. 4 is a section ofthe rear linl. Fig. 5 is a cross-section of same on line r Fig. G is a crosssection ofthe frame and forwardpart of carrier. Fig. 7 shows the application of the revolving cartridge-separator to the magazine. Fig. S is a cross-section of same on line v/ y. 9 is a side view ot' bolt, showing diagonal ejector. I() is a top view of same. Fig. ll shows a side view of loading-trap in the frame, and Fig. 12 shows sectional plan view of saine.

A represents the frame of the arm; I3, the bolt; C, the. carrier: D, the operating-lever, E, the ejector; L, the rear link; L', the forward link, I), the resisting-pin; T, the trigger; T, the scar; S, the cartridge-stop, F, the cartridgescparatorg 3l, the magazine; N, alever for withdrawing the firingpin; p, a spring to operate the ejector. O is the loading-trap, and O is the guide and cover for saine; s, spi ral spring for closing the loading-trap. The frame A is provided withareciprocating bolt, B, which is operated back and forward by the lever D through the links L and L, said links locking the bolt against the donble pin I?. The bolt Bis hollowed ont in its lower portion to receive the links L and L, the forward end of L being pivoted to the bolt near its face, and the rear end of link L pivoted to the frame through a slotin the bolt, and the forfarming part of Letters Patent No. 29,48, dated December :25, 1858,

ward pat of link L is provided with a slot which takes the pin (l ot' lever l) to operate the bolt in the manner well known in link systems; 'Jut the lever l) is bent near its upper end to fail clear ofthe links when the breech is opener as in Fig. 3. '3y this arrangement I am enabled to use heavy links in a strong continuons bolt, and by pivoting the linkLto the frameoy a pin with its strong rearward extension, I), to support the rear of said link, Fig. 2, gre it strength as well as case in assembling is obained. rI'he exiractors are fixed to the sidi; of the bolt in Figs. l and 3, and an ejer or is pivoted in the forward end of the bolt. Said ejector is provided with a spring to set the ejectorona center downward when the breech is closed, and when the breech is being opened a shoulder, e, on link L starts the projection on the ejector forward ot' the line of pressure on it of the spring p, when said spring drives the ejector' vertically upward to strike the head of the shell to throw it up clear ofthe frame. \\"hen the ejector is hung on the link-pivot, as here shown, the pivot is enlarged at one end to facilitate construction of parts. The carrier is split at the front end, and has spring sides pressing together, and I pivot between said sides a dog, s, Figs. l, 3, and 6, on which I form a wedgeshaped projection, s, rearward ofthe pivot, so the press nre of the sides of the carrier on said wedge tends to throw it downward, and thereby raise the forward end ot' dog S, as shown in Fig. 3, so by a slight rise ot' the carrier it stops the magazine, but when the Carrier is forced down, as in Fig. l, the rear or wedgeshaped piece ofsaid dog, striking the guard-strap, tnrns the forward end of said dog down io permit the cartridge to pass onto the carrier from the magazine.

It is obvious that the above dog may be op` erated by any ordinary spring in lien of the split carrier and wedge.

Figs. l and 3 show the trigger 'il pivoted in the guard-lever, so that it can only act on the scar 1" to discharge the arm when the breech is closed7 as in Fig. l, so the operator need not remove his finger from the trigger in ma nipnlating and firing the gun.

To hold the cartridges separate in the magazine, I use a spirally-grooved rod, Figs. 7 and 8. A slot is cnt in the side of the magazine and the spiral F hung longitudinally, so its side shall project into the magazine and engage the iiange of the cartridges in its groove.

As the said rod is free to rotate, the flanges ofthe cartridges move easily forward and back in its spiral groove, and as the flanges cannot pass out of the groove along the body of the rod they are held in the same relative position by the grooves when moved by the spiral spring, or any other means of propulsion.v

At N, Fig. 7, I show a modified firing-pin retractor consisting of a lever pivoted in the bolt and a link to force it back. Said retracting-leverhas also a spring to rotate it forward, so that by pressing against the link it holds the breech closed. I also show a diagonallymoving ejector in Figs. 9 and 10. It consists of a pin passing diagonally through the face of the bolt B, and a spring-stop, p, projecting through the side of the frame. rllhe stop p enters a groove, p', ofthe bolt, and when the bolt moves back the projection p pushes back the stop, stop, riding over, engages and starts the ejector positively forward until it clears the projection p, when it is free to spring the ejector' forward. I use the well-known slide and spiral spring to close the magazine-loading aperture in the side of the frame; but lto prevent it from coming in contact with the wood of the stock I insert the guiding-shield O within the wood and fasten it to the frame A, as shown in Figs. 11 and 12. The slideO moves freely inside of it and is guided by a rod on its forward end, which passes through a hole in the end of said guiding-shield, the whole being attached to and supported by the frame. A solid abutment of the frame may extend upward into the hollow of the bolt to resist the link L; but I prefer to use the removable pin P to facilitate the assembling of the parts. The pivoted vibrating carrier Gis hung leneath the bolt in the usual manner, and has an upward projection near the pivoted end, as is usual. (See Fig. 1.) This projection is engaged by link L the link swings backward, thus serving to raise the carrier.

I do not herein claim the firing-pin of Fig. 7, or the diagonal ejector of Figs. 9 and 10, or the loading-trap and shield, Figs. 11 and 12, as these are claimed in a pending application filed 'by me, office Serial No. 111,421.

Certain of the details shown herein (notably in Figs. 9, 10, 11, and 12) are not herein claimed, but are claimed in my application No. 111,421, filed November 10, 1883.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A reciprocating breech-bolt having a recess in its lower portion, a link, L, pivoted at the front of the bolt, so as to close into said recess, a link, L, pivoted to said front link and to a resistance-piece passing through the recess near the rear of the bolt, (when in compressing its spring, so that said. Y

closed position,) and an operating-lever connected to one of said links, all the parts being combined and arranged substantially as described.

2. A reciprocating breech-bolt having arecess in its lower portion, a link, L', pivoted at the front of the bolt within said recess, a a link, L, pivoted thereto and to a pin in the frame near the rear ofthe bolt when closed, a resistance piece immediatelyI in rear of the pivoted portion of said link L, and an operating-lever connected to one of said links, all arranged and combined substantially as set forth.

3. In combination with the frame and 9perative mechanism of a breech-loading gun, a double pin, l), having a portion which sei-ves as a pivot for a link or brace, as L., and a portion to the rear thereof, made strong to serve as an abutment, said pin passing removably through the frame and link, substantially as and for the purpose specified.

4. rFhe combination, with a reciprocating bolt, of links L and L, each constructed in one piece and occupying the lateral center of the bolt, said links being pivoted to each other and to the frame and bolt, and a downward extension on link L, having a eruciform slot, and the lever D, extended upward within the frame to carry a crosspin which enters said eruciform slot to operate the breech mechanism, substantially as set forth.

5. The con'ibination of an ejector hung in the face of the bolt, a link having a projection to start said ejector, and a spring to throw said ejector aga-inst the head ot' the cartridge-shell and strike it vertically upward, substantially as described.

6. In theframe of a magazine-gun,` avibrating carrier, mechanism to force said carrier up and down, and a dog pivoted within the carrier, and provided with a spring which slightly raises the carrier and turns up the front end of said dog to stop the magazine, in combination with an abutment in the bottom of the frame to turn said dog to open the magazine when the carrier is forced down, substantially as set forth.

7. rllhe carrier, pivoted, as described, at the rear of the lrame, and having a projection, as shown, in combination with the bolt-operating link L, located as described, so as to engage said projectiomand thus operate the carrier, substantially as set forth.

8. In combination with the magazine of a gun,a spirallygrooved rod pivoted outside of and projecting laterally into the magazine to engage the cartridgelianges, substantially as and for the purpose described.
