PAPER SHOT-SHELL.

Specification of Letters Patent.

Patented Mar. 12, 1912.

Application filed October 10, 1911. Serial No. 653,906.

To all whom 'it may concern:

Be it known that I, FRANK O. HoAcLAND, a citizen of the United States, residing at Bridgeport, county of Fairfield, State of Connecticut, have invented an Improvement in Paper Shot-Shells, of which the following is a specification.

This invention relates to reinforced paper shot shells and has for its object to provide a simple, inexpensive and ornamental means of insuring that the shell will not slip out from the head or break off at the inner end of the head in firing. In order to accomplish this result effectively and enable the shells to be reloaded and used many times without danger of their breaking in the gun barrel or the heads pulllng off from the shell, leaving the latter in the barrel, I have found that it is necessary to effect a double locking of the shell with the metal of the head, which I accomplish in the manner I will now describe, referring to the accompanying drawing forming a part of this specification and using reference characters to indicate the several parts.

Figure 1 is an elevation of a paper shot shell illustrating the application thereto of my present invention; Fig. 2 a longitudinal section corresponding therewith; Fig. 3 a transverse section on the line 3-3, looking in the direction of the arrows; and Fig. 4 is a view similar to Fig. 2, showing a shell with a shorter head and lining.

It will of course be understood that the length of the head or the lining or the thickness of the base wad are immaterial so far as the principle of the invention is concerned.

10 denotes a paper shell of the ordinary or any preferred construction, 11 a sheet metal head which may also be of the ord1- nary or any preferred construction, 12 an inner steel lining which ordinarily but not necessarily extends from the base of the head a distance equal to or greater than the length of the head, and 15 a base wad formed in the usual manner.

The novelty of the present invention lies in the mode of locking the shell to the head. In order to accomplish this result effectively, I provide the head with a depressed panel or panels, indicated by 13 and having portions of the metal raised from the base of the panel as at 14. The width and design of the panels are wholly unimportant so far as the principle of the invention is concerned, it being simply necessary that the raised portions of the metal of the head, indicated by 14, be surrounded or approximately surrounded by depressedportions so that a double locking of the paper of the shell with the head will be effected as I shall presently explain. In the present instance I have shown a plurality of depressed panels extending circumferentially of the head. It 1s wholly immaterial, however, whether one panel or a plurality of panels are used, and hkewise immaterial what design is adopted for the raised portions within the panel. In the present instance, I have shown the raised portions as letters rising from the base of the panel, which effect a peculiarly strong lock between the shell and the head.

In carrying out the present invention, the panels and raised portions are first formed in the heads, then the heads are placed upon the shells, then the linings are placed within the shells and then the lining is forcibly expanded outward, the effect of which is to expand the paper of the shell around the depressed panels and also to force the paper into the depressions which form the reverse of the raised portions rising from the bases of the panels. I thus eifect a double lock by causing the paper of the shell to expand around the panels and also to expand into the raised portions within the panels, so that it is rendered practically impossible for the heads to become detached from the shell.

In practice, the linings are light strips of steel of the required width with the ends overlapping. The base wad is formed from a roll of paper inserted within the lining and then compressed by a plunger to onethird, more or less, of its original length, so that a dense, hard, base wad is formed and in the act of forming this wad the lining is forced outward and forces the paper of the shell to interlock with the depressed panel and raised portions formed in the head. It is not necessary, however, that the depressed panels and raised portions should be in the portion of the head which corresponds with the base wad, as in Fig. et, as the same effect is produced by the combined action of the wad and the plunger when the wad is compressed, if the depressed panel and raised portions are higher up on a relatively long head, as in Fig. 2. The dotted line 16 in Fig. 2 indicates approximately the length of with a smooth exterior, portions of said shell being also expanded by said lining 15 around said depressed panels and also into the raised portions of said panels whereby a double lock between the shell and head is efiected.

In testimony whereof I aflix my signature 20 in presence of two witnesses.

FRANK o. I-IOAGLAND.
