MAGAZlN E FIRE-ARM.

- SPECIFICATION forming part of Letters Patent NB. 357.517, dated February 8, 1887.

Application filed September 1, 1884. Serial No. 141.910. (Xe model.)

To an whom it may concern.-

citizen of the United States, residing at Owego,

haveinvented certain new and useful Improvements in Magazine Fire-Arms, of which the following is a specification, reference being had therein to the accompanying drawings.

My ingention relates to breech-loading and magazine fire-arms; and it'consists in various improvements and combinations of parts, with the object of producing'greater ease of manipulation, rapidity and effectiveness in such arms by details of construction and co-operation of parts hereinafter more fully set forth and described.

, Fignre'l is a longitudinal horizontal view, in section, of the frame and breech. mechanism of this arm; Fig. .2, a reduced sectional view of the butt. as connected with red B". Fig. 3 shows a top or plan view of the extractor of Fig. 1 and a section of a modification of same. Fig. 4 is a bottom. plan and sectional side view of the brace T. Fig. 5 is a front view of the face of the bolt and its parts. Fig. 6 shows the dog 2' in the ham mer, and dog 1-" as hung in the bolt, and the head of rod B, as in Fig. 1. Fig. 7 is a crosssection through the hammer, the dog'r, and therod B. Fig. 8 is a detail of foil-lever i, the projection b being shown cut ed in horizontal section. Fig. 9 is a modification of foil-lever 1', (in reversed position.)

Similar letters of reference indicate correspending parts.

A isthe frame of the arm, A the lockingshoulder, B the bolt, B the locking-brace, E

the extractor,G the slidingguard, T the guard-.

and R the reciprocating rodlocking brace,

which eo-operates -to move thebolt and hammer.

The belt B is looked forward by the brace B, which turns down forward of the shoulder A, fixed in the frame. The sliding guard G,

having the sectional sleeve-extension R, to be grasped by the hand .of the operator, engages the projecting arm r of the pivoted brace, so that in sliding back the guard the forward wall of notch G engages the arm 9 to turn the brace B upward, or out of engagement with the locking-shoulder A, when the bolt is free to movebaek to open the breech by the continued backward movement of the sliding guard, and by the reverse or forward movement of the sliding guard the rear wall of notch G engages the arm 9 of the brace to move the bolt forward until the breech closes so far forward that the rear of brace B may be turned downward (by the forward pressure of the sliding guard on its arm 9) against the locking-shoulder A.

I make the notch G wider than the arm 9, "so the guard has a little lost motion, that it may strike a blow when required to start the breech in either direction. A brace, T, is hung in the sliding guard, with movement in- .dependent of the trigger, and may be open at its rear to pass the trigger, as shown in Fig. 4, and has a spring, t, to-turn its rear end up forward of the abutment T in the frame, to lock the guard in its forward position, and thereby hold the bolt and brace locked by bearing forward on the arm got the brace B.

trigger, as grasping pressure on its projecting forward end turns its rear part downward to unlock the guard and allow it to slide backward, and after the guard has thus started back ,and moved the braceto unlock the breech the roll t (which is hung in the center of the rear of the split trigger) moves so far back that it may engage the rear incline of the abutment T, so that the pulling back on the trigger in moving back the guard pulls the roll t against the incline T in the part of the movement of the is arranged in the forward the cartridge into the slots 2' iof the projection guard to start'back the breeeh-bolt by the lev;

guard, and has a forward b of the bolt to insure its risingtherein when acted upon by the carrier, and in closing the breech the said spring-stud stops the magazine after the carrier falls,until retired byits projection S.

The jaws b b extend downward from the face of the bolt, and have grooves i i to receive the-flange of the cartridge from the mouth 01' the magazine and guide the head of said cartridge upward against and forward of the face of the bolt, and when the carrier raises the cartridge its front heavy end has a tendency to fly up and out of the frame; but the guidingnotches 'i t serve to clamp the flange when it [5 begins to turn obliquely from its'vertical position, and so hiild the cartridge down in position to be forced into the barrel by theclosing of the bolt.

I here show, Figs. 1 and 5, one side of the ex-.

' tension carrying the jaws b b partly cut away to permit the loading of the magazine through the side of the frame,and the opposite jaw providcd with the foil or lever i, which is arranged in the jaw, so as to be engaged, as at 2 5 c, bythe arm 9 of the brace when said arm is moved to'its foremost position in locking the breech to press the forward end of lever i butward intothe notch i and bridge it, so that when loading the magazine the cartridgeo flanges will be guided forward on said lever or foil 6, so as not to be obstructed by the notch i,- but when the arm 9 moves back from the end 0" of the foil '5' it is 'free to turn out of the groove, so that said groove will guide and hold the cartridge-flange, as before described. The

foil-lever i may be hung in the magazine, and its ,rear end swing into the groove 1" in an equivalent manner .by operatioupf the brace or bolt inclosing the breech. 1 I 0 In Figs. 1 and 5 I show eirtractors E E on each side of the face of the bolt, forming a continuation of the grooves i'iabove the guidingjaws, and also a top extractor, E, which may be used in conjunction with the others, or alon e. V

5' The top extractor,'E', asshownin section, Fi 1, and in plan, Fig. 3, consists of a base, E, which carries the extractor E and sets in a deprossion in the bolt, where it is held by a screw or otherwise, and may be vibrated to turn back the extractor nearly or quite even with the face of the bolt, as shown in dotted lines, Fig. 3, to allow the cartridge to be'thrown laterally,from'the frame.

To turn back the extractor, I arrangeapi'o jection, as S, inthe framein the line of move-. ment of the point B of the extractor-base, so

that at the last part of the rearward movement of the bolt the extractor is thereby turned back to disengage the cartridge-flange, andin the forward movement the point S encounters .the lower projection, S", to turn the extractor again parallel with the bolt; or, as in the modification in Fig. 3, the extractor may be turnedto operative position by-a spring; but I make no specific claim to the vertically-. swinging extractor of the modification, as I show and claim It in my application No. 168,819, filed J une'15, 1885. v

The vibrating extractor described may be arranged on the side or bottom of the bolt to operate in a similar manner without essential change in the features of the invention.

I arrange arod, R, to reciprocate longitudi' nally in the stock of the gun, and preferably attach it to a telescopic butt-plate, (or to the rear of the stock when atelescopic joint is made at the small of the stock,) so that the forward part of said rod may engage the bolt or hammer, or both, to move them forward or back, as desired.

In Fig. 2 the rod R is provided with aspring to move it back; but a reverse motion may be obtained by a lever or any other known means, or the spring may be applied topress the rod in the opposite direction; but I prefer this or similar arrangement of the spring, by which it also acts as a buffer to ease .the recoil of the gun. When the breech. is nearly closed and the rod Rf is forced forward by the shoulder of the operator, or otherwise, its forward end engages the projection R" of the bolt to force the bolt home, the rod moving forward to the position shown in dotted lines,.Fig. 1, when by releasing the rod R from the force that pressed it forward-as removing it from the shoulder-the upper projection on the head of the rod engages the dog 1", which, is pivoted in the bolt, so that when the bolt is unlocked the rod, pulling back by means of its springbntt, 0r otherwise, tends to move back or assist any other means used to move back-and open the breech, and the bolt will becomedisbelowthe bolt in moving rearward, as to posinon shown in Fig. 1. false showa lower frame stops the dog 1 to turnit up, as shown foremost position, so the rod it may engage it and pull it back until it cooks the hammer, when its line of. movement willfall so far below the line of n'rovementnflthe rod as to disengage it therefrom.

, I here show the forward endof rod R, in

at one side of the hammer; but it may pass forward through a mortise in said hammer (or be split to pass both sides of it) to engage the dog 0-, so itmay pull back on said dog r to cock the hammer, which at that point turns the dog out of engagement with the rod B, as described. p

- The engagement of a butt-piece through the rod R with the bolt to close it may be direct against a shoulder of the bolt,-'as here shown,

or by a lever-connection, why any known engaged from the red by the falling of said rod IIO central position, and a projection, as p, in the in dotted lines, when the hammer reaches its Figs. 1 and 7, in position to project forward means, and the operation of said rod on the forward, thus bringing the opposing forces to rear part, F, ofthejointed firing-pin F.

bear upon the bolt inthe same direction and forcing the brceclrblock forward in the frame, not only by the force of the hand upon the lever or handle, but also by the resistance against that force which, as the shoulder against the butt of the gun, in this case, holds the gun in position. This gives greatly increased force on the closing-bolt where it is most needed to force the cartridge home and to force the 8X1 tractor-hooks over the cartridge-flange.

The red It" may be operated by the hand, or otherwise than by the buttplate, and may engage the bolt or hammer by a lever or similar device, without changing the nature of the invention; or a slide underneath may take the place of the sliding guard.

In Fig. l I show a link hung to the brace, which engages a jointed firing-pin to withdraw it and to hold said firing-pin out of the line of movement of the hammer when the brace is unlocked. One end ofthe link f is pivoted in the brace I3, and the other in a slot in the The turning upward of the brace to unlock the breech turns up the rear part of the firing-pin by the link f, and by forcing the upper part of the linkf obliquely backward, which forces the firing-pin backward in the bolt, and when the brace is turned down to its locked position, the slotted connection of the link with the firing-pin allows said pin the necessary movement forward.

The brace T may be omitted, or the trigger made in one piece therewith; or the trigger will lock the guard forward when pulled by its rear arm, turning up forward of the shoulder T; but I do not herein claim such coustrnction, as I claim it in my application No. 145,558,- filed October 15, 1884.

The laterally-swinging extractor claimed herein is shown, but not specifically claimed,

in my application No. 140,499, filed September I do not herein claim thepe'cnliar arrangement of sear described and claimed in my application filed July 15, 1884, to which case the Patent Office has given the Serial No. 137,812.

I claim- I 1. In a breeclrloading fire-arm, a breechpiece which is moved to open and close the breech, and a sliding guard which serves as a handle to lock and move the breech-piece, and means, substantially as described, to connect the guard and breech-piece, in combination with alever pivoted in said sliding guard, and a fixed abutment in'tho body of the gun to receive engagement of said lever to lock the guard and bolt in firing position, and a projection of said lever in position for engagement outside the frame.

2. In a breech-loading fire-arm, a slidingguard arranged to operate the bolt by connecting therewith, in combination with a lever pivoted in said guard, and a fulcrum, as '1", in the body of the gun anarm, as i, on the lever to engage said fulcrum, and a projecting arm or handle on said lever by which to operate it to start open the breech, sn bstantiall y as speci tied in 3.
