ADJUSTABLE MAGAZ INE PLUG Filed March 24, 1967 INVENTOR CHARLES CASSELL 3,371,440 ADJUSTABLE MAGAZINE iLUG Charles Cassell, 2708 SW. 44th, Oklahoma City, Okla. 73119 Filed Mar. 24, 1967, Ser. No. 625,848 (Jlaims. (Cl. 4249) ABSTRACT GF THE DISCLGSURE A plug adapted to be removably inserted into the magazine of a shotgun to absorb moisture which would otherwise impair the functioning of the shotgun, and in addition when necessary, to reduce the capacity of the magazine to two shells as required by law in certain states when hunting migratory birds.

Summary of the invention I provide a hollow cylindrical container filled with silica gel and open at both ends. An end cap removably fits in one end as a seal. A disc having a central threaded bore is disposed in the other end, the disc having a plurality of holes disposed between the bore and the disc periphery.

When the container is disposed with disc end inward into the shotgun magazine, the moisture created in the magazine by condensation therein (as the gun is fired and the resultant heating and cooling of the barrel produces heating and cooling of the magazine) is absorbed in the silica gel. This moisture will otherwise cause resulting and leave a residue; this combination can produce shell feed jamming and improper functioning of the shotgun.

In order to reduce the magazine capacity, elongated shaft means having an axis coincident with the axis of the cylinder is disposed in the magazine with one end secured to the disc bore and the other end bearing against the adjacent shell.

Brief description 0 the drawings In the drawings:

FIG. 1 is a side view of my plug in use;

FIG. 1A is a view through AA in FIG. 1;

FIG. 2 is a side view of my plug as fully assembled;

FIG. 3 is a view through 33 in FIG. 2; and

FIG. 4 is a perspective exploded view of the parts of my plug.

Detailed description of preferred embodiments Referring now to the figures, I provide a hollow cylindrical container filled with silica gel 12.

An end cap 14 having a lip 16 fits detachably in one end of container 10. A disc 18 detachably seals the other end of the container. Disc 18 has a central threaded bore 20 and four holes 22 (exposing the gel) equidistantly spaced between the bore and the disc periphery.

An inwardly tapering shaft 24, at its larger end, has a reduced diameter extension 26 threadedly engageable with bore 20, the shaft axis being coincident with the container axis. The shaft has a central threaded bore 28 3,371,440 Patented Mar. 5, 1968 at the other end. A cylindrical extension 30 has, at one end, a reduced diameter threaded extension 32 engageable with bore 28, its other end being rounded.

In use the entire structure can be placed inside the hollow magazine 34 of a shotgun 36 with lip 16 in contact with the open end and the rounded end of extension 30 in contact with an adacent one of two shells 36, thus providing the desired reduction in capacity. Spring loading can be provided by coil spring 38 circumferentially disposed about shaft 24 and extension 30, with one end passing into follower 40 and bearing against the disc of the follower. The other side of the follower bears against the shell.

For trap and skeet shooters requiring full magazine capacity, shaft 24 and extension 3t can be removed. Extension 30 is used when regular size shells are used and can be removed separately when longer shells (such as magnum) are employed.

The device can be made of aluminum, ebonite and various plastics and can be varied in dimension to accommodate its use in all brands and gauges of automatic and pump shot guns.

While I have described my invention with particular reference to the drawings, my protection is to be limited only by the terms of the claims which follow.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A plug insertable into a shotgun magazine to reduce the shell capacity thereof, said plug comprising a hollow cylindrical container filled with silica gel,

both ends of the container being open;

a cap adapted to be removably disposed in one open end of the container to seal same; and

a disc detachably disposed in the other open end of the container, said disc having a centrally disposed threaded bore and a plurality of holes equidistantly spaced and disposed between the bore and the disc periphery.

2. A plug as set forth in claim 1 further including an elongated slightly inwardly tapering shaft, the larger shaft end having a threaded extension engageable with the disc bore whereby the shaft extends away from the disc and container and has an axis coincident with the axis of the container.

3. A plug as set forth in claim 2 further including a generally cylindrical extension engageable at one end with the other end of the shaft and having an axis aligned with the shaft, the other end of the cylindrical extension being rounded.

4. A plug as set forth in claim 3 wherein said cap engages the open end of the magazine and said cylindrical extension bears against the adjacent shell in the magazine.

5. A plug as set forth both in claim 4 further including a coil spring encircling the shaft and cylindrical extension, one end of the spring bearing against a follower, the other bearing against said container disc.
