lMPRVEMENT IN BREECH-.LOADING FIRE-ARMS.

Speeilieatiou forming To all whom, it muy concern:

Be it known that LJOHN HiNsoN, of Rashcliile,near Huddcrsticld,inthe county of York` ngland, 'have' invented or discovered certain '.l-mproveincnts in ilrcech-Loading Fire-Arms, and in the Manufacture of Cartridges for the Same; and I do hereby declare that the following is a full, true, and exact description thereof, reference being had to the accompanying drawings, and to thelettersand figures marked thereon--that is to say z My improvements in fire-arms relate to those arms which are furnished with drawback closing-bolts5 and it consists in an improved arrangement of mechanismby which the arm is opened ready to receive a charge, the empty cartridge-ease extracted and thrown automatically from the arm, andthe piece placed in position for firing in one operation. The invention will be well understood by referring to the. accompanying drawings, of which Figure 1 is a sectional elevation of a gun with the parts in the position they occupy after the explosion of a charge;- and Fig. 2 a similar view with the parts in the position when the insertion of a cartridge takes place and the striker is set at full-cock.

I fit in the fore end ,of the closing-bolt a a striker, Z), formed with a button, c, at its back end for a coiled spring` 7, to act against to keep' the point of it flush with'the face of the closer a. Behind the striker b is abolt or rod, e, which is encircled by a coiled spring, f, held in a tube, g, to direct its action and preventy the coils overlapping. The tube g also serves as a guide for the closing-bolt a to work upon in its to-and-fro movements. cured at the back end to the rear portion of the breech-piece, which rests in the stock A. The bolt or rod e is formed with two heads, h, 4to it the tube g at one end, and the smaller head, @which rides inside the coiled spring f, at the other. This smaller head, when the arm is cocked, is caughtby a catch, j, and held in`that position until the arm is ready for firing.

The underside of the closing block or bolt is provided with a hole, 7:, into which a safetypin, Z, on a double-inclined lever, B, is free to enter when the holt a is entirely closed. The lever l3,with the piu l, iskept balanced by The tube g is separt of Tieiters Patent No. [09,3l, dated November 29, 1870.

means of. a spring, 1n. .In consequence of this safety-pin having no hole to enter into, except the one on the sliding bolt a, the gun is locked fast and cannot be discharged, either by accident or iutentioinuntil the closing-bolt a-is placed home in vposition for firing. Then the pin Z can enter the hole 7.', and the gun maybe discharged. It' the closing-bolt is moved but one-eighth of au inch from that position, the gun again becomes locked. This gun'oiers great facility for examining and cleaning, as the barrel is open at both ends. The double lever B is in connection with a projecting tail, n, of the trigger (5.

The fore cudof the closing-bolt a carries an extractor, p, in a slot, the extractor having a certain amount of -play allowed it, so that it is free to move when the cartridge is forced home in the chamber to engage itself` with it.

There is a bent lever, D, litted in the stock, one end, q, of which is struck by the extractor p in its backward movement, when it has traveled a certain distance. This striking .causes the other end, fr, Aof theforked lever to come forcibly against the empty cartridge-case and eject it through the opening inthe barrel autonia-tieall y.- \Vhen the rod is drawn back, the smaller head is forced downward by means of a spring, s, fitted at the mouth of the opening through which it protrudes.

A pin, t, on the rear end of the trigger-C, is made to take under the small headz' of the rod or bolt e, and on the triggerCbeing drawn back the pressure overcomes the action of `thc spring s and the catch j, and releases the plug, when the force of the coiled spring d drivesit to the front of thel closing-bolt a with suffi cien-t force to shoot the striker-pin b against the base of the cartridge,to explode the cap or fulminate.

I tit alever and disk, E, in the top o1" the stock A. *A portion of the disk is cut away at u, as seen in the detached view, Fig. S, io allowthe small head of thcbolt e-.to rise-when it is required to tire the arm; but when it is necessary to retain the arm in a loaded and cocked position, the lever is turned partly around to bring a-full part, r, of thcdisk upon the small head 'i of bolt e.

In some cases-it is essential that the cxtractor should be so made that it shall be caused toaet as un ejector as Well as an extractoxgand this is accomplished by fitting a tailpiece, 1v, on the under side of it, as shown vin the sectional View, Fig. 4, which is similar to Fig. 2 in all other respect-s. This combined extractor and ejector is acted upon bythe stop or end ofthe slot in which it is engagethto draw the cartridge-case clear of the bore'ai'ter each ,discharge, and when it has traveled a certain distance the tail-piece w comes against the xed stop sv andcauses it to tilt upon its pin, as shown in the ligure. lhe degree of force or speed with which it is necessary to eject the case will of course depend upon the speed and power with which the closing-bolt is drawn back-that is to say, the greater the speed and sharpness of action in `opening the breech the more certainty of action is cxpelling the'empty caseis obtained. rIhis re- .mark not only applies to this last-mentioned arrangement, but to the first-mentioned one as well. This disk, before referred to, isfcentered upon a pin o r stud, y, let into the top of Vthe stock, and-it is free'to be turned bythe pressure ofthe thumb againstthe proiecting head1', as seen in the plan view, Fig. Fig. 6 represents 4the back end of' the breech with the catch y' andthe springs fitted thereto.

1. The plug or rod, with two heads within a tnbe,to be acted upon in the manner and for the purpose hereinbefore described,and'shown inthe laccompanying drawings.. i

2. 'A tube for containing the coiled spring, and to serve as a guide for the closing-bolt. to slide upon, in the man-nerhercinbetbrc shou'n and described. .I

The disk with a projecting thumb-piece.,`

:induit-h a portion of the edge cut. away for retaining the arm at full-cock, or for freeingv -it ready, for the discharge, -as hereinbefore Shown and described.
