40 carrying member with which the barrel carrying member when in closed position will register with interlocln'ng means on the stock of the firearm. With the above and other objects in view as will hereinafter appear my invention comprehends a novel firearm.

It further comprehends a novel firearzn wherein the barrel is readily detachable and is carried by a carrying member which causes it to register with novel interlocldng means. M

It further comprehends novel releasing means for the firing pin.

Other novel features of construction and 2a advantage will hereinafter more clearly ap pear in the detailed description and the appended claims.

For the purpose of illustrating the invention, I have shown in the accompanying drawings typical embodiments of it, which, in practice, will give reliable and satisfactory results. It is, however, to be understood that these embodiments are typical only and that the various instrumentalities. of which my invention consists can be vari ouslyarranged and organized, and the invention is not limited to the precise arrangement and organization of these instrumentalities as herein set forth.

Referring to the drawings In a co-pending application for a com bmed club and firearm, Serial No. 322,204, I have described and broadlyclaimed a novel construction of a double acting firin mechanism which is similar in some respec s to that shown in this application.

1 desi atesthe stock of the firearm which is provi ed at its rear end with a depending or oflset grasping portion 2. The stock is chambered as at 3 to receive the firing mechanism which includes a firing pin casing 4 within which is a firing pin 5. 6 is a firing pin spring interposed between a closure nut 7, in threaded engagement with the firing pin casing, and a shoulder 8 on the firing pin.

elevation of the barrel The firing pin 5 is cut away to form a shoul- ,,der 9 and its forward end is reduced at 10,

which, if desired, may be encircled by a retracting spring 11. The stock has secured to it a breech 12 in the form of a ring having a diaphragm 13 provided with an aperture 14 throu h which is adapted to pass the striking ,end 0 the firing pin 5. This barrel 12is secured to the stock in any desired manner and, as illustrated, in Figure 5 the stock s re-v cessed to receive the rearwardly "extending annular flange of such breech. The stock is recessed to receive a block 15. to which the firing pin casing 4 is fixed in any desired or conventional manner so that it is accurately positioned within the stock. The stock is recessed as at 16 to receive the trigget 17 which latter has connected to it a sleeve mechanism which may be emtrigger member is moved downwardly terlocked therewith, said breech having reg-- v 18 which is provided with a slot 19 which extends through the sleeve and into a portion of the trigger 17 so that it is adapted to receive a firing pin actuating member 20 which normally tends to move upwardly due to the.

provision of a spring 21. wThe sleeve 18 is slidably mounted on the firing pin casing 4. The breech 12 is provided with circumferentially spaced lugs 22 forming circumferentiall spaced recesses 23.

T e breech 12 has hinged to it at 24 a ring 25 which is provided with circumferentially spaced ribs 26.

27 designates the barrel which is provided with the circumferentially' spaced ribs 28 each of which is provided with a recess 29 in its periphery into which is adapted to extend a locking plun er 30 and a locking member 31 which exten s into a recess 32 in the breech 12 and which is normally retained in its forward or looking position by means of a spring 33. The locking member 31 is provided with a contact portion 34 which preferably has its outer face inclined forwardly.

he firing pin casing 6 is cut away as at 35 on its bottom face and terminates in the cam portions 36. The trigger member 20, as shown in Figures 5 and 8, is rectangular in cross section and the slot 19 is also rectangular to receive such trigger member while in Figure 9 and aperture 37 is provided to receive a cylindrical plunger 38 which is moved outwardly by means of the spring 39. In Figure 10 instead of usin the trigger member such as 20 or.38, a sprlng 40 is employed and the sleeve is cut away to permit such spring to move inwardly, and the trigger 41 is pivotally carried by the sleeve instead of being fixed thereto as in the other figures as shown. A trigger retracting spring 42 cooperates with the sleeve 18 to effect the forward movement of the trigger and retain it in its forward position.

It will now be apparent that, assuming the parts are in the position seen in Figure 5 and the barrel and its carrier 25 are swung upwardly, the barrel 27 will be in alignment with the breech 12 so that when it is moved rearwardly it will pass into the breech 12 the lugs 28 passin through the recess 23 and the barrel 27 can t en be turned in a counterclockwisedirection until the locking pin 30 engages a recess 29 whereupon the barrel will be locked in accurate ali ment.

Assuming now that t e firearm is loaded, the cartridge or shell being contained within the barrel 27 in the usual manner, the user draws rearwardly the trigger 17 which causes the trigger member 20 to engage the shoulder 9 and move 'the firing pin 5 rearwardly. During this rearward movement the trigger member 20 rides on the walls of the cut away portion 35 and as it comes into contact with the cam portions 36 the meaees against the pressure of the'spring until it is released from the shoulder 9 whereupon the firing pin sprin 6 which has been com- L pressed causes the ring pin 5' to move forwardly to eflect the firing-of the cartridge.

When it is desired to remove the cartridge or shell which has been fired, the user places his thumb or finger'on the contact portion 34 of the locking member 31 and draws it rearwardly, thereby causing the locking pin 30 to become disengaged from the recess 29 in the barrel 27 whereupon by a clockwise movement of the barrel 27 and the upward longitudinal movement, the barrel-will move into the ring 25 to interlock therewith and the barrel can be swung into the position seen in Figure 5 ready for the removal of the exploded shell or cartridge.

In some cases arising in'practice it is not necessary to have the barrel carrier, and aligning member 25 as the firearm will operate in the same way and in some cases this can be dispensed with. It is, however, a dis tinct advantage in having the barrel carrier 25 hinged to the breech since it enables one to hold the firearm in one hand while reloading. If the barrel carrier 25 is not employed it will be' apparent that the barrel is inserted into the breech by a longitudinal movement and then partially rotated to engage the locking mechanism. Y

It will be apparent that any desired or conventional type of cartrid ployed in' thebarrel and a su -gaug e' barrel may be inserted in the barrel 27 if desired to adapt itfor different types of shells or cartridges.

It will now to apparent that I have devised a new and useful firearm which embodies the features of advantage enumerated as desir; able in the statement of the invention and the above description, and while I.have, in the J can be empresent instance, shown and dscribed'pre v ferred embodiments thereof which will give r 1. In a firearm, astock, a breech on the stock, a barrel carrier hingedsto the breech,
