IMPROVEMENT lN yBREECH-"LOADING FIRE-ARMS.

Specification form-ing part of Letters Patent Nc.l132,740, dated November 5, 1872. 'i

To 'all whom it may conce-rn:

Be it known that I, WILLIAM MONT STORM, ot' the city, county, and State of NewYork, have invented .certain ner and useful Improvements in Breech-Loading .Fire-Ar1 ns o t' which the following is a specification:

M y invention relates to breech-loaders of the class having pivoted or swinging breeches.

1. The object of the rst part of my invention is to impart an upward vertical movement to the breech piece or gate when closed against the end ofthe barrel, thus causing the gate' to pa'ss behind an abutment, which sustains the gate against the recoil of the explosion, and a reverse, movementafter the. explosion to release the gate; and this I accomplish by combining a suitably-shaped cam with the breechgate, as hereinafter specified.

2. The object of the next part of my invention is so to combine the breech-gate4v havin the movements above mentioned that the hammer may be cocked by the act of opening the breech; but the charge cannot be exploded while the breech is open orieven unlocked.`

3. The objectof the next part of my invention is to hold the breech sccurelyagainstthe force of the explosion to prevent the breech being blown open; and this I do by combining the breech, a gate, and its operating-cam, having the movements above described, with an abutment or locking-jaw on the breeching, into which the barrel is screwed, as hereinafter specified.

4. .The object of the next part of my invention is to eject the exploded shell, which I do by combining the breech piece or gate, operating as above described, with an ejector pivoted within the stock and actuated by the breechblock itself, as hereinafterspecied.

5. The object of the next part of my invention is to enable the operator more readily to manipulate the gun 5 and thisI do by constructing the operating or breech-opening lever of the gun with an extension infront as well as in rear of its axis, as hereinafter set forth.

The accompanying drawing shows all the improvements herein claimed as embodied in asin gle arm; obviously, however, some of them may be used separately from the .others and in arms differin g in construction from that herein shown.

Figure l represents avertical longitudinal y central section through so much of in y improved gun as is necessary to illustrate the invention claimed, with the parts in the relation they assume at the moinentof firing. Fig. 2 represents a similar section, with the hammer at half-cock and'the-breecli-piece partially drawn down.` Fig. 3 represents a similar section with the breech Vfully open. The position ,of the working .lever isshown in dotted lines'in the preceding figures. Fig. 4 represents a hori- Zonta-l longitudinal section through the barrel with the breech open. Fig; 5 represents a vertical transverse section through the gun, showing the cam 5. and Fig. 6, a view in perspective ofthe working lever and cam.

My gun, in this instance, is shown as adapt. ed to thcuse of a primedcentral-re metallic cartridge.

An open-ended barrel, A, is screwed into aj breaching, B, open behind in like manner. A back-strap,fB1, connects thisbreeching securely with the upper side of a stock, O, while a similar 1ockstrap,B2, connects thefunder side' of the stock and breeching. This strap also carries .the few parts constituting thelock. A mainsprin g, D, secured in a'cavity in the stock,

is connected by a link, d, with a hammer, E,-

vibrating centrally in the'stock on a pivot, e, and havingapointed nose to penetrate through an opening in thefbreech-block or gate to ignite the charge. The hammer, whcni'ull-cocked, sinks into a' recess in the stock, so as to lie below the plane of the bore, so as to oii'er nol impediment to the removal -or insertion of the cartridge. The trigger F needs no description. The gate or b reech-piece Gr is of peculiar construction, as shown'inthe drawing, and has both a vertical and an' oscillating movement imparted to it by means of a cam, h, Working in a yoke in the gate.` The upper partjot' the gate is iiat and adapted to close the breech, as seen in Fig. l, where it rests with its upper end in a groove formed by a strong jaw, hook, .or

abutment, g, on the breeching. The lower part ofthe gate is curved, as shown, so that when the breech is closed the jaws of this gate may abut aga-inst the shoulders of the back-strap B1, and thus sustain the gate against the strain ofthe explosion. The cam h rocks on a. pivot, h', and is actuated by a lever, H, mounted onl its projecting end outside or" the lock-plate. This lever, itwill be observed, beside theusual and backward in opening the breech.

below the bottom of as also does the hami v 'in g the cartridge.

'less the 4hammer abnts against the bottom or rounded thumb-piece h2, has a projection, h3, in front ofy its pivot, which front projection movesupwqad gate, when opened, lies the bore of the barrel, mer when full-cocked, both of which are thus well out of the Way when inserting or remov- The hammer can be cocked x without moving the breech-piece, but, if prei ferred, it maybe cocked by theopening of the breech-piece.

breeclris closed, as when open the part of the breech-piece before striking the lupper part. -(See Fig. 2.) In opening, the breech-piecev descends vertically far enough to clear the `jaw g,vas in Fig. 2, and then swings outward and downward into the position shown in Fig. 3. As4 assumes thisposition prongs y2 on it abut against'the toes i of an ejector, I, pivoted on thesame axis as the hammer, and

y cause the ejector to vibrate, thus expelling the cartridge-shell. The ejector, it will be seen, requires no spring, being opened bythe breechpiece and closed by it, or by the insertion of the cartridge. It works entirely within the lock-plate, where it is protected from harm and y does not mar the symmetry of the gun.

' I claim ns'my inyentionl1,'The combination of the oscillating vertic v allylmoving brcech-gaterand the cam which The charge cannot be fired unv 'imparts these movements to it, thesevparts i being4 constructed and operating in combination, substantially as set forth.

2. The combination of the oscillating vertic- `vally'mvingbreechgate and the hammer, these `members being constructed and operating in combination, substantially as set forth, so that the hammer maybe cocked by the opening of the breech-gate, and to prevent accidental explosion.

.3. The combination ofthe locking-jaw on lthe breeching'with the oscillating verticallymoving breech-gate and its cam, these parts cam,and an operating-lever swinging vertically parallel with the barrel and projecting on both sides of its axis, substantially as set forth.

Will-MONT STORM.
