ASSIGNOE TO WESTERN CARTRIDGE GOZM- A CORPORATION OF NEW JERSEY.

CARTRIDGE.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, ROBERT G. CLYNE, a subject of the King of Great Britain, residing at Alton, in the county of Madison and State of Illinois, have invented certain new and useful Improvements in Cartridges, of which the following is a specification.

My invention relates to improvements in cartridges, and more particularly to metallic base caps for securing and anchoring the paper shell or tube' of that class of cartridges known as paper shot shells The primary object is to improve upon and reduce the cost of the material entering into a metallic base cap of this class, and at the same time give it greater strength and providing against rust or oxidation as is done where the entire cap is made of a nonferrous metal, such as copper, brass, or the like.

A further object is to provide a double walled or laminated metallic base cap, the inner wall or shell being preferably made from ferrous metal, such as iron, steel, or the like, and the outer wall or shell being made of a thin layer or covering of nonferrous material, this outer Wall being of comparatively thin material but of sufiicient thickness to exclude the air from coming into contact with the inner or thicker shell of ferrous material thereby preventing rusting or oxidation.

A still further object is to provide an improved form of metallic base cap having its mouth or rim portion reinforced by means of an inwardly extending hooked beading formed about the upper marginal edges of the outer shell or covering and extending over and interlocking with the upper marginal edges of the inner shell or main body portion composed of the ferrous metal.

With the above mentioned and other ends in view, the invention consists in the novel construction, arrangement, and combination of parts, hereinafter described, illustrated in some of its embodiments in the accompanying drawings, and particularly pointed out in the appended claims.

Referring to the drawings forming a part of this specification, Figure l, is a sideelevation of the cartridge constructed in accordance with my invention, a portion of the improved metallic base cap being broken away and shown in section for the purpose of clearer illustration of the parts.

PatenteolMay e. 1913..

The improved metallicbase cap to which this invention particularly relates, comprises 7 a double-walled or laminated base cap, the main or inner wall or shell 3, being composed of suitable ferrous metal, such as iron, steel, or the like, and the outer shell or covering 4, being of nonferrous metal, such as copper, brass, or the like, this outer covering or casing being preferably of relatively thin material, but of sufficient thickness to exclude the air from the main wall or shell 3, and thereby preventing the rusting or oxidation of this part of the base cap.

The outer shell or covering 4, is preferably provided about its upper marginal edges with an inwardly extending hooked heading 4, extending over and interlocking with the upper marginal edges of the inner wall or shell 3, thereby not only reinforcing and strengthening the mouth of the metallic base cap and forming an interlocking anchor heading for interlocking with the subjacent portion of the paper shell or tubal, but also sealing the rim portions of the inner and outer walls and thereby excluding the air from between the walls and preventing any rusting or oxidation at the rim portions of the base cap.

The improved metallic base cap may be.

provided with the usual peripheral base flange 4, for holding the cartridge in position within the breach of the gun barrel, and the base or bottom portion thereof may be provided with a battery cup receiving opening or primer pocket 5, of any suitable and convenient form for the reception of a suitable primer or a battery cup 6, such as shown, for example,-1n Fig. 1, of the drawmgs. 4

From the foregoing description, taken-in connection with the accompanying drawings,

the construction and advantages of my inventionwill be readily understood.

Having thus described some of the em- -ferrous metals, respectively,,said outer shell bodiments of my invention, what I claim having an annular hooked flange taking over and desire tosecure by'Letters Patent is,- and en aging the rim portion of said in- 1.
