FIREARM.

SPECIFICATION forming part of Letters Patent No. 717,958, dated January 6, 1903. Application filed September 13. 1899. Serial Fn. 730,358. (No model To all w/eom, it nto/.y con/cern:

Be it known that I, JOSEPH C. WHITE, of Chelsea, in the county of Suiolk and State of Massachusetts, have invented a new and useful Improvement in Firearms, of which the following is a specification.

Myinventionis animprovement'on the com,- bined pistol and knife described in my Patent No. 626,472, dated June 6, 1899; and it consists in a novel lock and novel means for cocking the gun, as fully described below and specifically claimed,

Figure l is an elevation, partly in section, of one form of my invention. Fig. 2 is an edge View ofthe article shown in Fig. l. Fig. 3 shows thetrigger detached. Fig. 4 is a detail ot the firing-plunger.4 Fig. 5 is a section on line 5 5 of Figs. l and 2, and Fig. 6 is a detail hereinafter referred to.

In the drawings, A, B, and C represent three plates of substantially thef same shape, and between the plates A and B are located the barrel D 'and the lock or firing mechanism, and between the plates B and C is located the knife-blade E. The barrel D and knife-blade E are both pivoted upon a bolt d', so that the blade 'E may be swung into its open position in the usual manner and so that the breech of the barrel D may be swung out from between the plates A and B to a limited extent, as shown by dotted lines in Fig. 6, in order that a cartridge may be inserted or a shell extracted.

The breech-block F supports the side plates A and B and the back plate G, which is secured at its other end to the block H by means of the screw g. The block H is formed with a threaded socket in which is fitted the threaded end of a rod I, and the opposite end of the rod I is secured in a socket in the breechblock F by means of a screw f. The rod I guides the tiring-plunger J, which is moved lengthwise on the rod I in on'e direction by hand and in the opposite direction by the spring j, which bears at one end against the breech-block F and at its opposite end against the ring-plunger.

To one end of the firing-plunger J is pivoted at j a finger-piece jz, which lies within a slot g2 in the back` plate G and has a projection extending outside of the stock, which when moved to the rear by the finger turns the finger-piece on its pivot j', so that it may be grasped by the hand. (See Fig. 6.) The iinger-piece is then moved to the rear by the hand, and with it the firing-plunger J on its guide I into the firing position. When inoperative, the finger-piece jg lies within the stock, as shown in Fig. l.

The tiring-plunger J is notched, as atj3j4, and these notches are engaged by the free end of a spring-soar js, which is secured to the backfplate G by rivets g3. Whenthe firingplunger J is in its tiring position, as shown in Fig. 6, notch ,i4 is engaged by spring-scarf. To tire the pistol, the sear j is moved out of engagement with the notch L7'4 by means of the trigger K,Which is pivoted on a pin k, fast on the plate B. The inner end of the trigger K isformed with-a slot Zc, into which extends a projectionj6 on the free end of the searj. The part k2 of the trigger K, which is located at one side of the slot Zc, is yielding, so that as the tiring-plunger J is drawn back by hand v the part 762 will yield as the free end of the searj5 rides along the firing-plunger.

On the rod I is a split washer t", the ends of which are separated, and said washer is located between the endof the firing-plunger J and the check-nut t' andY serves as a yielding abutment against which the end of the firing-plunger strikes and to return the firingplunger toits half-cocked position. (Shown in Fig. l.)

vThe iiring-plungerJ is provided with an offset or projection f, which engages the cartridge in the barrel D when the plunger J is A thrown forward by the spring j.

The barrel D is notched on one side at d2 for the spring-catch d3, which is secured to the breech-block F by the screw d4. This notch and catch serve to lock the barrel D in its closed position. The catch d3 is thrown out of the notch d2 by the pin d5, which is mounted in a socket in the breech-block F and extends through the plate A to the outer side thereof.

The pin k, on which the trigger K is pivoted, extends through a slot lam in said trigger, and a portion 7622 of the trigger K projects IOO through the slot g4 in the back plate G and is formed of a convenient shape to be engaged by the thumb of the operator, and a notch 7c3 is formed in the trigger K at that end which is normally held by a spring 7c, located between the block H and trigger K, in engagement with one end of the slot g4 in the back plate G, as shown in Fig. 6, so that in order to disengage trigger K from the back plate Gr the trigger must be moved bodily against the force of the spring 7a4 until the notch k3 is moved out of engagement With the back plate G, and when this has been done the trigger K may be swung on the pin lo to disengage searj5 from the firing-plunger J and the latter released. 'lhetrigger is normally locked in a fixed position and cannot be moved to release the tiring-plunger Without first disengaging it from the back plate, and accidental discharge of the piece is thus prevented.

What I claim as my invention isl. In a firearm the lock above described, comprising a firingplunger; its spring; a notch in the plunger to receive a yielding sear; that sear; and a trigger with a slot receiving a projection from the sear, and with one'wall of the slot yielding to allow motion of the Sear as the notch in the plunger forces the engaging end of the sear to one side.

2. In a firearm the combination of a firingplunger bored longitudinally; a fixed rod extending through that bore; a spring to throw the plunger forward on that rod; means for moving the plunger on that rod against the force of the spring; a Sear for retaining the plunger when in its cocked position; and a trigger for releasing the sear from engagement with the plunger.

3. In a firearm the combination of a firingplunger; a spring for that plunger; means for moving the plunger against the force of the spring; a sear for locking the firing-plunger; a back plate; a trigger movable endwise and slotted to engage the back plate; a spring to hold the trigger-slot in engagement With the back plate and thereby prevent the trigger from being tilted to release the Sear until after the trigger has been moved endwise and its slot released from the back plate.
