JAMES T. \"ALKER, OF BALTIMORE, MARYLAND.

WAD-RETAlNER FOR CARTRIDGES.

SPECIFICATION forming part of Letters Patent No. 289,191, dated November 27, 1883. Application filed October 10, 1883. (X0 model.)

To all whom it may concern Be it known that I, JAMES T. WALKER, a citizen of the United States, residing at Baltimore, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Cartridges, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain improvements in shot-cartridges; and it has for its objects to provide a device which may be fitted in the shell over the wad, and which will hold the wad and prevent its starting, thus obviating the necessity of crimping the shell.

The invention further has for its object to prevent the gun from fouling by the peculiar construction of the device for holding the cartridge, as more fully hereinafter specified.

These objects I attain by the means illus trated in the accompanying drawings, in

which- Figure 1 represents a perspective view of my improved device; and Fig. 2, a vertical sectional view of a cartridge, showing my invention applied thereto.

The letter a indicates an annular washer, constructed of thin brass or other metal, of suitable diameter to fit within a shell. The said washer is split or cut away at one side,at b, so as to permit the washer to contract and expand to the diameter of the shell or bore of the gun. The inner circumference 'of the washer is preferably slightly corrugated, so that when the device is placed over the wad in the shell the corrugations will be flattened by the pressure of the loader, which will tend to cause the outer edge of the device to bear firmly against the walls of the shell, thus securing the wad so firmly in position that it will not jar loose, but will be held firmly until fired.

The washer is in most instances provided with a flange, c, which scrapes the deposit left by aforrner discharge from the bore of the gun, thus preventing fouling. In some instances, however, the flange may be dispensed with; but it is always preferable, as, besides cleaning the gun, it tends to keep the device in shape, making it stronger.

Having thus described my invention,what I claim, and desire to secure by Letters Patent, 1s

1. A device for securing the wads in can tridge-shells, consisting of an annulus of thin metal split or cut away at one side, substantially as specified.

2. A device for securing the wads in can tridge-shells, consisting of an annulus of thin metal split at one side and having a flange at one edge, substantially as set forth.

3. A device for securing the wads in cartridge-shells, consisting ot an annulus of thin sheet metal split at one side and having its inner circumference corrugated, substantially as specified.

4. A device for securing the wads in cartridge-shells, consisting of a split metallic annulus, corrugatcd,as described, and provided with a flange at its edge, substantially as and for the purposes set forth.

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