BREECH-LOADING FlR-E-ARIVI.

SPECIFICATION forming part of Letters Patent No. 379,257, `dated March 13, 1888.

Application filed April 17, 1884.

To all whom t may concern:

Be it known that we, REINHARD T. TORKEL- sON and IVER JOHNSON, both of the city and county of Worcester, and State of Massachusetts, have invented certain new and useful' Improvements in Fire-Arms, of which the following is a specification.

Our invention relates to improvements in breech-loading fire-arms; and it consists in a novel arrangement of the locking-bolt and the hammer, whereby the bolt is Withdrawn by partially cocking the piece; also, in the mech anism for actuating the extractor and means for rendering this mechanism inoperative.

In the accompanying drawings, Figure 1 is a side elevation, the stock and part of gunbody being removed. Fig. 2 isa longitudinal section through the parts shown in Fig. 1. Fig. 3 is a side elevation, partly in section, of a modified forni of our invention, and also shows the screw for securing the barrel to the shell. Fig. 4 is a bottom view showing the triggerguard. Fig. 5 shows the cartridge-extractor.

lThe hammer A is provided with a projection, a, which, on the first movement of the hammer when being cocked, engages one alm of a bell-crank lever, a, provided with a spring, @that tends to depress the arm next the hammer and throws the other arm into a notch, b, in the lug b. The further movement of the hammer A raises one arm of the lever a against the spring a2 and withdraws the other arm from the notch b, thereby leaving the barrel B free to turn on its pivot b2, so as to bring its breech in position for receiving a cartridge. The lug b serves also as a lsupport for parts of the cartridge-extractor mechanism hereinafter described, and is preferably employed for receiving the bolt-in this instance an arm of the lever a-for locking the barrel in position f for firing. hen the usual sliding lockingbolt, b3, is desired, it may be connected to the arm of the lever a' by a suitable device, such as a pin and slot, as shown in Fig. 3.

The trigger-guard d is inserted in aslot made in the under side of the body D. To make this slot without filing or other hand-finish we use a circular cutter, which cuts it at one operation and makes its ends arcs of a circle. The

Serial No. 128,202. (No model.)

dotted 4lines in Figs. l and 2 indicate that part of the periphery of the circular cutter that enters the body in cutting the slot.

The guard d is shaped on a milling-machine, so that its surfaces which come in contact with the slot in the body D are also arcs of the same circle, and consequently iit the slot accurately.

The cartridge-extractor consists of a plate, F, shaped on one edge to correspond with the lower half of the bore of the barrel and provided with pinsff, which enter holes drilled lengthwise of the barrel and serve to guide the extractor. The plate F extends on each side of the barrel to form projections f2 f3, by

means of which it may be pulled out. A projectiomf, on plate F enters notch g in the end of the extractorslide G, thereby causing the extractor to move in both directions with its slide G. By means of a groove, g', in the upper bar of the slot coming in line with the pin g in its slot, the slide G is rendered capable of being tipped suliciently to allow the edge of the notch g to come below the projection f4L and release the plate F, so that the extractor may be withdrawn.

By making the extractor detachable dii'er ent styles of barrels may be used with one body, D. The slide G is actuated bya lever, g3, pivoted at g4 between the lugs b. One end of the lever g3 bears on the end of the slide G, and is caused to move the slide rearward by means of a spring hook, gi', pivoted at g to the guard d. 'lhe hook g5 catches the other end of thelever fas the barrel is tipped, and causes the lever to turn on its pivot until its end is withdrawn from the hook g5 by reason of its movement in a circle having its center in the pivot b2. A spring, gs, located in the slot in the slide G, draws back the slide and the extractor as soon as the hook releases the lever g3. A tail, gl, to the hook g5 extends outwardly, so that by pressing on it with the thumb or finger the hook may be thrown into an inoperative position, so as to allow the barrel to be tipped without expelling the cartridge.

In the arm shown the rear portion, b5, of the barrel B is made to t snugly but detachably in the shell b, so that when in place the shell and barrel are practically one. A screw, bl, fitted in the fore lug, bs, at an angle, as shown in Fig. 3, enters a notch, b9, in the barrel and serves to draw the barrel and the shell together, and. efectually prevents any turning or displacement of the barrel.

We claim as our invention- 1. The barrel B, pivotcd at b2, and its lug b', in combination With the locking-bolt a, catch a, and hammer A, the locking-bolt a being pivoted and the hammer A bearing against the catch a, also pivoted, to trip the lockingbolt a', substantially as and for the purpose specified.

2. The barrel B, pivoted at b2, its lug` b, and extractor-slide G, in combination with lever g3, fulcrumecl at g, and springliook g5, fulcrumed in the fore part oi' the frame, the lever g3 acting upon slide G to force it rearward,

and the spring-hookg5 engaging therear end of leverg3, substantially as and for the purpose specified,

3. The barrel B, its lug b', and extractorslide G,in combination with leverg3,fulcrumed at g4, and spring-ho0k g5, provided with tailpiece 07, and fulcrumed in the fore part ofthe frame, the leverg3 acting upon slide G to force it rearward, spring-hook g5 engaging the rear end of lever g, and tailpiece g7 extending outside the frame, substantially as and for the purpose specified.
