APPLIANCE FOR sno'rcruns.

Specification of Letters Patent.

Patented Apr. 11, 1916.

Application filed July 20, 1915. Serial No. 40,961.

To all whom it may concern Be it known that I, HENRY K. MAYER, a citizen of the United States, residing at Fort Collins, in the county of Larimer and State of Colorado, have invented certain new and useful Improvements in Appliances for Shotguns, of which the following is a specification.

This invention relates to shot gun appliances and has as its primary aim to provide a cartridge chamber which may be fitted into the breech of the shot gun and which is constructed to receive a ball cartridge of relatively small caliber in such manner that the same may be discharged by the firing mechanism of the shot gun.

The device embodying the present invention is designed primarily for use in raising ducks and other game and is not, as are devices of this general class heretofore devised, intended as an auxiliary barrel for the shot gun designed to permit of the gun being employed as a rifle.

On the other hand, it is an aim of the invention to so construct the appliance that when the gun is broken, it will be ejected in the same manner as the ordinary shells employed in the gun and therefore in its use, after the ball cartridge placed therein has been fired and the game has been raised and the shot cartridge in the other barrel of the gun has been discharged at the game, the empty shell and the appliance will both be ejected when the gun is broken, and the ordinary shells may be inserted in the two barrels of the gun, and the gun may then be put to its ordinary use.

In the accompanying drawings: Figure 1 is a view partly in elevation and partly in section illustrating the device arranged within the breech of a shot gun. Fig. 2 is a perspective view of one form of the invention. Fig. 3 is a vertical longitudinal sectional view through the device, a ball cartridge being shown in elevation within the bore of the device. Fig. 4. is a vertical transverse sectional view through the device. Fig. is a side elevation illustrating another form of the device. Fig. 6 is an end elevation of the form shown in Fig. 5.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

The device embodying the present invention comprises a tubular body 1 which is exteriorly of the same diameter and length as the ordinary cartridge shell and in order that the device may be readily and conveniently inserted within either barrel of the shot gun, it is exteriorly tapered at its forward end, as indicated by the numeral 2. At its rear end, the device is provided with an annular rim 3, corresponding to the rim of the ordinary shot gun shell, and this rim is continuous and unbroken for a purpose to be presently explained.

The bore of the body 1 is indicated by the numeral 4 and, if desired, may be rifled, as lndicated at 5, in the same manner as the bore of a rifle or other similar fire arm, the bore being flared at the forward end of the device, as indicated at 6. The bore 4 is of a diameter to receive a ball cartridge of small caliber, as for example a 22 or a 32, and the rear end of the body is formed with a shallow recess 7 surrounding the corresponding end of the bore 4.

The numeral 8 indicates a ball cartridge which is fitted within the rear end of the bore land the rim of this cartridge, inclicated at 9, abuts against the wall of the recess 7 at the said end of the bore, the re cess being of a depth to permit the rim of the cartridge, if the same is a rim-fire cartridge, to lie flush with the rear end face of the body 1 or of a suificient depth to permit the cap to lie flush with the said rear end face of the body if the cartridge is of the center-fire type. If constructed to receive cartridges of the center-fire type, the bore at is located in axial alinement with the body 1, but if the device is designed to receive small cartridges of the rim-fire type, the bore 4 is located eccentrically with respect to the axis of the body, as clearly illustrated in Figs. 5 and 6 of the drawings, so that, regardless of the manner in which the device shown in Figs. 5 and 6 is inserted within the barrel of a shot gun, the firing pin of the gun will strike the rim of the cartridge when the corresponding trigger is pulled.

As before stated, the rim 3 of the device is in both forms of the invention continuous and unbroken and corresponds in every respect to the rim of an ordinary shot gun cartridge, and after the device has been inserted into the breech of the gun and the ball cartridge inserted therein has been fired and the gun is broken, the ejector of the gun will cooperate with the rim 3 to eject the device or to withdraw the same to such a position that it may be conveniently removed. It will be observed, furthermore, that, unlike previously devised appliances of this class, the device of the present invention is not provided with any means for ejecting the shell of the ball cartridge, which ejecting means or devices have heretofore been actuated through the ejector of the shot gun and, consequently, the device of the present invention may be inserted within the breech of the gun without any attention being paid to the exact position to be occupied thereby. In fact, in the use of the device, a ball cartridge will be inserted therein. and the device may be car ried in ones pocket or in a cartridge belt until it is desired to use the same, when it may be inserted into the breech of the gun in the same manner as the ordinary shell.

As before stated, the forward end of the appliance is exterior-1y tapered or rounded and the corresponding end of its bore is flared, as indicated at 6. By reason of this construction, tne appliance may be readily inserted into the breech of the gun and there is no likelihood that the appliance at its forward end will become so battered as to interfere with the free passage of the bullet. Furthermore, by so forming the appliance it is less likely to wear holes in the pocket in which it is carried.

Having thus described the inventiomwhat is claimed as new is:

In a firearm appliance of the class described, a body adapted for insertion into the breech of the barrel of a firearm and provided with a cartridge receiving bore, the rear end of the body being provided with a circumscribing continuous and unbroken rim corresponding to the rim of the shell to receive which the barrel is gaged, said rear end of the body being further provided with a recess the Wall of which is flared, the said recess surrounding the rear end of the bore and being of a depth to re ceive the rim of a cartridge to be fitted within the bore with the primer cap of the cartridge located in the same relative position to the end surface of the body as would be occupied by the primer cap of such shell, the said body at its forward end being exteriorly conoidal whereby to permit of its ready insertion within the said breech of the barrel, and the said body at its said end having the corresponding end of its bore outwardly flared, the forward end edge of the body between the flared wall of the bore and the conoidal exterior surface of the body being blunt and rounded.

In testimony whereof I afliX my signature in presence of two witnesses.
