  • Patent number: 4272903
    Abstract: Disclosed herein is an improved reloading device of the type described in my prior U.S. Pat. No. 3,769,732 wherein the center shaft of a revolver cylinder is utilized to displace a latching mechanism retaining a ring of cartridges by the rims thereof. This latching mechanism is in the form of a slidable center post which in one position will oppose the inward bending of a plurality of cantilevered fingers each provided with a semicircular projection abutting the rim of the cartridges, and which, upon the invert articulation thereof, will release the cartridges for insertion into the cylinder. Included also are spring-loaded carriers conformed to support the foregoing reloading devices and to eject the devices into the hand of the wearer upon release.

A tray is provided that is removably supported in the first cup. The tray supports a number of cartridges in spaced groups, with the spacing of the cartridges in each group being such that they may be slidably inserted in a revolver reloading device when the body of the latter is moved inwardly towards the tray when the cups are in a second position.When in the first position the cups preferably define a first compartment therein in which a loaded revolver reloader is disposed for instant use. Also, when the cups are in a first position the reservoir may be carried or supported in a depending position from the handles thereof.
