ANDREW? BURGESS, OF O\VllGO, NEW YORK.

MAGAZINE-GUN.

SPECIFICATION To aZZ iff/mm, it' may crm/:crit:

ile it known that I, ANnnnw Boneless, a citizen ot'the United States, residing at Owego, in the county of Tioga and State of New York, have invented certain new and useful lmprovements in Magazine Fire-A rms, of which the following is a specification, reference being had thereiato the accompanying draw. ings.

My invention relates to magazine lire-arms, and has l'or its object ease, rapidity, and certainty et' operation; and it consists principally in modifications and improvements of my ap` plieation No. 171,940, ot' July 1S, 1885.

Figure l is a longitudinal side elevation of the frame and operative mechanism of this Fig. 2 is a cross-section on the line x x of Fig. 1. Fig. 3 is a crossscction through the rear ot' the bolt and tiring-pin, to show arrangement ol' the cooking-dog and rollers. Fig. 4c is a detached view ol' thesliding piece, which operates the brace. Fig. 5 shows the `eonstructiou ol' the brace. Fig. (5 is a face view of the side extractors. top and sectional View of the boltand bolt attachmentsy A is the frame, B the bolt, C the carrier, D the cooking-dog, 1*) E the extractors, F the firing-pin, G the guard, II the hammer, L the locking-dog, and L its operating-rod. M is the magazine; 1t, the rod or strap to connect the guard and slide-piece S. ll is the trigger; T', the scar; T, a linger-piece to release the locking-dog. Lis a pulling-off ily andf ally to cock the hammer. r is a roll in said fly; r', a frictionAroller in the frame. c is an ejector and pulling-hook, p a piu in slide S to operate the brace, and W a weight on rod L.

r1he general construction ofthis arm is similar to that shown in my application No. 171,940,- but I will proceed to describe various details wherein it diil'ers from said arm, and which I desire to claim in this application.

The side extractorfhooks, E E, are widened downward as to the bottom ot' the bolt, so that when the cartridge-head is thrown upby the carrier between the extractors it enters between the lower parts of the extractor-booke to be guided thereby upward and held by its forming part of Letters Eratent No.l 366,564, dated July 12, 1887. Application tiled August 27, 18H3.

Serial No. l75;fl.'l.'). (No model.)

l l l l l l l construction ofthe frame and vibrating car rier the extractors serve lo stop and guide the feeding cartridges.

The sliding piece S carries a passes through a curved a straight longitudinal slot in the sides ofthe bolt. Said slide-piece is l'ormcd as a cylinder or sleeve at its top to encircle the tiring pin li, and has a downward extending arm which is engaged by the sliding strap it, which connects the operatinghandlc tothe sliding piece S, to thereby move it back and l'orth to open atc thel brace and bolt.

The ejector c is arranged to expel the carv tridge-shells upward, as in my lateut No. 289,972; but it is also provided with a spring to turn it downward, and a hook at the bottom ot'its l'ront end to engage the cartridges and pull them back into the l'rame in the same manner as the pull1ng-dog p in my application No. 113,436, of December 3, 1883, and the hook ofthe ejector' is raised out ofthe line ol" the magazine, as shown in Fig. 1, slide-piece S when the breech closes.

The carrier is arranged to be forced nearly but not quit-e down by the closinglholt, which slides along its top forward ofits pivot, ani an incline in the front end ofr the carrier is then engaged by the incline t" of the strap ll to force the carrier below the line ot' the magazine, asin Fig. 1; but in the first backward movement of the strap lt to open the breech its incline z engages a corresponding incline rearward on 'thc carrier to raise the carrier a little,"and thereby stop the magazine.

hang a ily,f, with a roller, r, in the rear of the bolt. I here show it pivoted to the tiring-pin; but its action is substantially the Same when pivoted or arranged as a sliding lly in the bolt. The roller-ily bears back the hammer to cock it when the bolt moves back to open the breech, and the roller r, project' ing below that portion of the bolt or its parts above the hammer or immediately to its Front, turns the hammer so far back as to be held at full-eock below that portion of the bolt or its parts forward of the ily, so that the `bolt passes back freely-over the nose ofthe hammer until the rear lower part, s, of the slide S reaches and depresses the nose of the hanr mer, so that it will bear thereon with elastic slot in the brace and piu, p, which turns back on reaching the nose of the ham,

mer to pass over it without friction. I also 4nivot a roller, 1", inthe top of the frame, to .engage the bolt and decrease the friction of the top ot' the boltvagainst the top of the frame as the bolt is being opened and the hammer bearing against the ily or bolt when being cocked thereby.

The automatic cooking device here shown is not claimed herein, as it is shown in various forms in my applications No. 168,819; of June 15, 1885, and No. 171,940, of July 18, 1885.

l arrange a ily'or movable piece, t, in the trigger to engage the scar when it is in position to hold the hammer cocked, as shown in dotted lines in Fig. 1, so` that if the trigger-is then pulled it turns the scar, asto the position there shown in full lines, to disengage it from lits notch in the hammer.

When the piece t will have passed so far as to be in position to tu rn forward a-nd no longer obstruct the movement of the sear, (the spring of the y, if used,l

being so much weaker than the scar-spring as not to resist its operatiom) so that if the hainmer be again cocked while the trigger is yet being pulled, the scar will spring into plaee'to hold it, and when the trigger is releasedlit' will be turned 'againinto operative position by its spring t, the ily-piece turning back of its tired sufficiently by the turningof the trigger.

The above is a modification of the'trigger of my application No. 171:940, in which the pulling-piece is locked by a spring-*catch arranged to' be released by a set-screw'in the fixed guard strap.

A. dog or lever, as L, is pivoted in the frame or fixed part of the gun to engagethe sliding handle or a part moving therewith, to lock the handle forward or in positionv to hold the breech closed. I' show the dog L pivoted -in the guard-strap and provided with aspring to turn its pivoted on the same pin with the trigger, but with independent movement, and has a projection, as t, near the base of the triggenby which i'amay be engaged to unlock the slid-` ing guard by turning its vrearpart'inward'A against the locking-dog- 'to press' itout`of the" pull the trigger near its ,lower point, will not need to engage or operate the unlocking-piece,

ving in y y widened, part being concave tobear against. 4segmental shoulders in the top of thebolt point of engagement on the sear when rei forward part outward, behind ashoul-` der of the sliding guard-handle, to lockthe guard forward, and an unlocking-lever, T, is=k fstantiallyas described.

but whcnJas in tiring rapidly, it may be desir'- able, the finger can engage the unlockingpiece and the trigger near its base at the sanie time.- v

The unlockinglcver maybe `provided with a hook, as h, to engagea shoulderin the frame and lock the handle independently of the dog L. A rod or movable piece, as L', is arranged rearward of thelocking-dog, in position to be engaged by said dog when the recoil of the discharge thrusts back the gun, the inertia of rod L insuring such action,so that the inclined ends 'of the dogand rod strike together to turn the dog out. of engagement with the sliding handle to unlock it, so that if the operator is pulling back en the handle in firing, the recoil unlocks it andthesame pull of the operator which presses'the gnu against his-shoulder slides back thehandle to open the breech. A spring, as show-n, may hold the rod out of contact with the dog, (but will. be compressed by the recoil, asj aforesaid,) and a weight, as W,

may be added to therrod, when desirable, to

increase thepower-of its blow onthe dog L.A The bracois pivoted in the bolt and has a segment bearing therein forward of its pivot,and said brace is'widened rearwardto fill the openthe top of the'frame, the .front of such rearwardof the brace-pivot. (See Fig. 7.)

I do `notconfin"e my claim to the lever form of the unlocking dog or piece shown,v as other mechanical equivalent(to 'produce 4.the same result) may be used-or ,substituted by obvious changes in construction, and the unlockingpiecev and also the locking-dog maybe ap- .plied insubstantially the same manner to other 'well-knownoperating-handles.

I claim-- 1. In a magazine tire-arma 'reciprocating bolt, a pairofy ,yielding extraetors located at lthe sidesof-the,bolt-face and provided with downward-eirtending hooks integral therewith to guide. the cartridge upward before the face of the bolt by its flange, in combination-with fa' carrier which raises the cartridge-flange to a position between said extracting-hooks, sub- 2. Inlabreech loading gun, a reciprocating bolt, alockingbrace, a sliding pieceguided to' longitndinalmovement inv the'bolt and surrounding 'thering-pin, but having movement independent ofythe firingpin movement, and- `h`avin`g al downward projection connectedto a link, R, operated by the sliding operatingspring to turnr said ejector downward, and a hook thereonv to engage and pull back the car-A tridges from the magazine in opening the IIO breech, and means, substantially as described, to turn the ejector-hook upward out of engaging position in closing the breech.

4. In a magazine fire-arm, a hammer and a sear arranged to engage the hammer to hold it in a cocked position, in combination with a trigger and alprojeetion carried thereby and having movement relatively to the trigger, all combined and all arranged in such relative position and line of movement that the pulling of the trigger first bears its projection against the Sear to release it from the hammer'a'n'd then carries it past its engaging position toalstaniiall y as described audthe scar to engage it while the trigger is yet being pulled.

5. In a magazine fire-arm, a hammer and a sear arranged to engage the hammer to holdit in a cocked position, in combination with a vtrigger carryinga fly to disengage the sear from the'hammer bythe rstpart of the movement of pulling thc trigger and then pass its engaging point on the sear by its further movement, and a springto return the trigger to operative position when the trigger isreleased.

v 6. In a breech-loading Iire-arma sliding handle and means, substantiallyas described, to lock it, a trigger, andgau unlocking-piece hung at the base of the trigger and having dle by the same backward pull of the nger. l

7. In a breech-loading fire-arm, a dog arranged to engage and lock a sliding handle, and in combi nation therewith,aud arod or weighted deviee,with which the locking-dog engages by ,the force of the recoil of the gun to unlock the iow the hammer to be cocked by meansl subs' handle, substantially asspecited.

-8.' In a breech-loading firearm, a sliding` handle and ay dog. yarranged to engage said handle to theixed'part ofthe gun to lock it, in

`combination with a rod or weighted device,

substantially as described, with which the dog engages by force of the recoil of the gun in ring to unlock the handle, and a spring to hold l the unloekingrod out or" contactwith the locking-dog.
