The invention described herein may be manufacturedand used byor for the Government for governmental purposes, withoutthepayment to me of anyroyalty thereon. invention relates to a holder tridges. V ,t

Whenka holder for discharging a projectile is tobeairned at a target it usually has the form of the conventional pistol witha hand-grip at for caran angle to the barrel forthe purpose of facilitating aiming. I In *thistype cf weaponthe recoil is absorbed by the arm "or the operator and the capacity, of the operator to absorb the recoilof the piece is a limitingfactor on the size i6, and range ofthe projectile.

* When the projectile, suchas asignal or flare,

"fl is .notwto be aimed at a target but is merely to 1 be firedin a general direction, there is no pur- 11 pose in providing angularlty between the handr ll andbarrely e 'Iheprincipal object of the present invention is to. provide a holder in which the barrel andhandle are on substantially the same axis where- I by thef butt of the handle may be placed on any 85 convenientsupport to absorb the shock oi .re=-

coil. novel and inexpensive flringmechanism dismounted inthe handle. e

The invention is also directed to a simple provisionfor holding the cartridge case in the barrel and for subsequently extracting the case whereby the operations, of loading, firing and l extracting may be performed with one hand. a With the foregoing and other objects in view, the invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed. a

j it being understood that changes in the precise yembodiment of the. invention herein disclosed 40 maybe made within the scope of what isclaimed without departing from the spirit of the invention.: g

A practical embodiment of the invention'is illustrated in the accompanying drawing, where:

g. l is a longitudinal sectional view of a holder constructed-inaccordance with the in vention. Fig. 2

Fig. 3 is a view in elevation of the cartridge.

Fig. 4 is a view showing the positon ofthe parts of theilring mechanism after the hammer has been fired and showing the position of the is a reduced view elevation of the hammer in dotted'lines at the moment of its release. i

Referring to the drawing by characters of reference, the improved holder consists generally of a handle A and a barrel B in prolongation of the handle and on substantially the same axis. In the preferred embodiment of the invention the handle and barrel are separate members so that they may be readily connected, the specific connection consisting of a threaded stem 5 on the handle receivable in a threaded aperture 6 in the base i of the barrel. I W

The stem is provided with a counterbored recess 8 opening into a chamber 9 in the handle, and housing a firing pin ill. The firing pin is normally held in retracted position, with its rear end projecting intothe' chamber 9, by means of a spring H, one end of which is seated on a collar l2 of the firing pin and holds the collar against an annular shoulder iii of the recess 8. The other end of the spring is seated on a plug l4 threaded into therecess 8 and having a central aperture ii for guiding the front end of the firing pin. V

Positioned within the chamber 9; and directly in rear of the firing pin is a hammer i 6 having an arm ll which is apertured to receive a mounting pin i8 supported by the handle. The arm is preferably provided with a slot IQ for receivlng a sear mounted on the pin I 8. A flat spring 2| secured to the hammer by a screw 22 has one end engaging the, sear and serves to hold the sear with its:inner side 20a against the hammer and in aposition of non-rotative engagement therewith.

A safety lever 23 working in a slot 24 in the handle is mounted on a pin at its upper end and has a foot 26 engaging a recess 21 in the hammer. The lower end of the lever is 'provided with a slot 28 receiving a pin 29 fixed in the handle and limiting movement of the lever. A flat spring 30 disposed in the chamber 9 and secured by a screw 3| engages the slotted end or the lever and normally maintains the foot 26 in engagement with the hammer.

A trigger lever 32, working in a slot 33 in the handle opposite tothe slot 24 accommodating the safety lever 23, is mounted on a pin 34 at its lower end. A spring 65 secured to the trigger by a screw 36 has a curved extremity 3'! acting on a curved face 380! the hammer. The upper extremity of the trigger terminates in a foot 39 provided with a slot 40 for receiving a pin ti fixed in the handle and limiting movement of the trigger. A toe B2 on the foot 39 of the trigger is engageable with the sear 20.

The elements or the trigger mechanism are shown in normal position in Fig. 1, the firing,

pin being cocked and the hammer being held in safe or inoperative position. In grasping the handle, the .hand of the operator encloses the safety lever-23 as well as the trigger lever 32. Pressure exerted on the trigger lever 32 cannot be effective unless pressure is also exerted on the safety lever 23 to move it out of the path of rotation of the hammer. The inward movement of the trigger lever 32 acting on the sear 20 rotates the hammer about its pivot and compresses the spring 35. I

As indicated in Fig. 4 the toe 42 of the trigger, moving on a radius greater than that of the sear, overrides the sear when the trigger indicated in the'dotted lines is at the limit of its inward stroke. When the trigger is thus disengaged or released from the sear, the spring 35 acts to counterrotate the hammer and drive it against the firing pin. During this movement of the hammer the sear 20 has-moved behind the toe 42 is returned to its normal position by the sear spring 2|. When pressure is released from the safety lever 23 it is rotated by its spring 30 and its foot 26 engages the hammer.

The muzzle of the barrel B is formed with a ccunterbored recess 43 whose wall is engaged by an annular head or corresponding projection 44 of a cartridge case 545. The frictional engagement of the bead against the wall of the barrel is suflicient to hold the cartridge against the blow of the firing pin. Except for this engagement the cartridge case has a looseflt in thebarrel.

The forward portion ofthe cartridge case is provided with a flange l6 that extends over the front edge of the barrel. The exterior surface of the muzzle of the barrel is beveled as at so as to expose more of the flange. The flange serves as a means for extracting the cartridge case from the barrel. It may be directly engaged by the] hand of the operator or it may. be caught on a more or less rigid article and extraction effected by pulling back on the holder AB.'

The cartridge case is provided with the usual primer 48 and the projectile 49 carried by the cartridge case is a flare or signal, the detail construction of which formsno part of the present invention.

When the holder is to be used in an airplane, the cartridges are carried in a rack so that the holder can be loaded by merely moving the barrel over the cartridge case until the bead or projection 44 is frictionally engaged by the barrel. The base of the holder is then placed on a convenient support and the firing mechanism actuated by contracting the hand. The operations of loading, firing and extraction of the empty cartridge case may be easily and quickly performed, using only one hand.
