  • Variable speed common axis control sprockets used in a shell casing unloading device
    Patent number: 6202534
    Abstract: A handling system for brass shell casings in an ammunition handling system. A shaft has a first sprocket and first hub and a non-circular gear mounted thereto, and because of the non-circular gear, rotates at a variable speed when driven by a power source. A second hub, coaxial with the shaft and rotatable independently of the shaft, has a second sprocket and a circular gear mounted thereto, and because of the circular gear, rotates at a selected speed when driven by the power source. The speed of the first sprocket varies between being equal to the speed of the second sprocket to being less than the speed of the second sprocket so that one end of a shell casing mounted on the two sprockets first lags behind the other end of the shell casing, then catches up to the other end of the shell casing.
