Application filed August 5, 1914. Serial No. 855,115.

To all whom it may concern Be it known that I, CiiAnLns XV. Rnnvns, a citizen of the United States, residing at New Haven, New Haven county, Oonnecti cut, have invented certain .new and useful Improvements in CartridQeShells, of which the following is a full, clear, and exact description.

My invention relates to improvements in cartridge shell construction, the object being to provide a simple and effective reinforcing means to prevent the forward end from bulging.

In the ordinary shell in which the main part of the cylinder is made of paper or other like material, the crimped forward end of the shell frequently becomes bulged or mushroomed, thereby either ii'npairing its operation in'the magazine and barrel, or making it wholly inoperative.

In the use of an ordinary "magazine shot-- gun, the user inserts into the magazine say, five or six loaded cartridges or shells. Ordinarily, after discharging: the arm once or twice and using up one or two most shells, he replaces the used shells with new ones, leaving in the forward end of the magazine, three or more of the shells that were first introduced. It has been found that the repeated shock of discharging! the gun tends to cause the forward end of the shells remaining in the magazine to bulge or mushroom, thus not only making it difficult or impossible to insert such shells in the chamber of the barrel, but sometimes even impairing the operation of the shells within the magazine itself. My improvement prevents this. I

In the accompanying drawings: Figure 1.

is a perspective View of my improved shell;

Fig. 2 is a perspective View of an ordinary shell, not equipped with my improvement and illustrating the appearance of the shell after it has been injured as aforesaid; Fig. 3 is a side elevation, partly in section, of the forward end of the shell, shown in Fig. 1; Fig. 4 is arelatively enlarged perspective view, partly broken away and in section, of a detail; Figs. 5 and 6 are similar views of modifications of the detail shown in Fig. 4.

1 is the rear end of the shell ordinarily made of brass.

' 2 is the main body of the shell, the same being in cylindrical form and ordinarily made of paper. \Vhen the shell is loaded of the rcarin the ordinary construction, it is customary'to insert a wad 3 and finally crimp in the forward edge of the main body to hold the wad and charge in place. It is this crimped portion, which, by reason of the fragile character of the body 2, frequently becomes upset, bulged or mushroomed, as shown in Toprevent this, I employ a reinforcement which cooperates with the crimped forward end to hold it up against endwise shock. In one form of'my invention, shown in Fig. 4, this reinforcing; member comprises a cupped member 4:, of approximately the diameter of the inside of the shell 2, the open end of the cup facing outwardly, the crimped portion of the shell body being turned into the cup around the annular wall thereof,-the bottom of the cup resting upon the Wad 3, which in turn is supported by the load within the cartridge. By this means the otherwise relatively weak crimped edge of the cartridge body is stoutly reinforced so that it cannot become bulged, when subjected to such shocks as occur within the magazine upon the firing of the gun.

Fig. 2.

in Fig. 5, I have shown at 4 a modificaof the reinforcing element, in which the center of the bottom of the cup is cut out or open. I

in Fig. 6, the reinforcing element 4 is still further modified by turning up a flange (3 around the inner edge of the central opening in the bottom of-the cup, thus making a channel to receive the extreme edge of the inturned or crimped portion of the shell.

It is obvious that the reinforce may be modified in a variety of other ways without departing from the spirit or scope of my invention, the means herein shown, however, illustrates certain preferred forms.

The reinforcing element may be made of any suitable material, preferably thin metal, such as brass. The outer edge of the annulus around which the body material is crimped should, of course, be made blunt, or otherwise shaped, to prevent cutting the material crimped around same.

What I claim is: I
