DESIGN FOR A SOLID-HEAD CARTRIDGE-SHELL.
SPECIFICATION forming part of Design N0. 26,677, dated February 23, 1897.
Application filed August. 3, 1896. Serial No. 601,566. Term of patent 14 years.
To all whom, if Um ('nn/w'u:
lie it known that l, JOHN GARDNER, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Design for a Solid-Head, Metallic, RiinlessCartridge Shell; and I do hereby declare the following, when taken in connection with the accompanying drawing and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawing constitutes part of this specification, and represents a side elevation of a solid-head, metallic, rimless-cartridge shell formed in accordance with my design.
This invention relates to a design for a solid-head, metallic, rimlesscartridge shell; and the design consists in the configuration of the shell, as shown in the accompanying ill ustration and hereinafter described.
My newly-designed solid -hcad, metallic, rimless-cartridge shell has its body A formed at apoint nearbut slightly forward of its head A with two shallow wave-like circumferential grooves or crinkles a a, located at a. right angle to its longitudinal axis, the groove or crinkle a being slightly narrower and also slightly shallower than the groove or crinkle a, and the two grooves being separated from each other by a distance fairly represented by the width of the groove or crinkle a. The said body of the shell or case is very slightly tapered and is formed Well toward its forward end with a long sloping bevel or shoulder A which in turn merges into a long cylindrical neck A". The head A' of the shell is cylindrical and corresponds in diameter to the diameter of the rear portion of the body of the shell. The said head is encircled by an annular extmcting-groovc A, having sharplydefincd edges located at a right angle to the longitudinal axis oi the shell and forming the line of dcinarkation between the body and the head thereof. This groove is deeper than either the groove or crinkle (L or the groove or crinkle u and is distinguished in particular therefrom by having sharply defined edges and side walls of much sharper pitch. The extreme rear end of the head is beveled, as at A The essential feature of my design lies in the shallow grooves or crinkles a a when formed and arranged as shown and when employed in conjunction with the deeper groove A having sharply-defined edges, and also in conjunction with the other features of the shell, as specified.
I claim- The design for a solid-head, metallic, rimless-cartridgc shell, as herein shown and described.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
