Abstract: A conveyor drive roller with a replaceable sleeve defining a conveyor drive surface adapted to operatively engage a conveyor belt. The replaceable sleeve may be replaced with another replaceable sleeve defining another conveyor drive surface adapted to operatively engage another conveyor belt. A method of replacing the conveyor drive surface on the conveyor drive roller is also disclosed.

Abstract: A roller for a conveyor comprising a cylindrical core defining a support surface; a helical groove disposed in said support surface and lagging bonded to said support surface.

Abstract: A shaft support or mount for supporting a conveyor roller and for dampening the vibrations of the conveyor roller or conveyor roller assembly in operation, by providing flexible connection structure in the shaft support, which is usually comprised of rubber. A method of dampening the transmittal of vibrations from a conveyor roller by providing a flexible connection structure in the shaft support.

Abstract: A support for supporting the end of a shaft protruding from a conveyor roller for dampening the vibrations of the conveyor roller by providing a flexible connection between spaced first and second supports where the supports include structure for resisting the separation of the rubber. A method of dampening the transmission vibrations of a conveyor roller assembly is also provided.

Abstract: A self cleaning conveyor roller for supporting a conveyor media carrying contaminant materials. The conveyor roller consists of a drum defining a support surface, having a generally cylindrical shape, and being adapted to be supported for rotation, for supporting a conveyor media. The conveyor roller has a plurality of abutments on the support surface, raised above the support surface, and defining a series of spaced apart conveyor media support ridges lying on a circular configuration, concentric with the drum. The abutments are arranged in generally chevron shapes, around the drum. During rotation of the conveyor roller the abutments cause any debris or contaminants between the roller and the conveyor media to be guided out of the conveyor system. Also disclosed is a method of cleaning a conveyor roller.

Abstract: A motorized conveyor roller having a rotatable portion and at least one stationary end.

Abstract: An intermittent internal drive system for a drum conveyor, where the conveyor is started, stopped and restarted and having a drive drum with a hollow interior, a drive motor mounted within and enclosed by the drum for rotating the drum, a clutch located within and enclosed by the drum and connected to the motor and for transmitting rotation from the motor to the drum, and, a brake within and enclosed by the drum and connected to the drum for restraining rotation of the drum.

Abstract: An internally powered conveyor roller, of the type used for driving a conveyor one direction, and for preventing movement in opposite direction and having a drive roller for driving the conveyor medium, an internal drive motor for driving the roller, a one-way rotation device permitting rotation of the roller in one direction, and for preventing rotation in the opposite direction, and the one way rotation means being moveable between engaged and disengaged positions, and when in the disengaged position, being inoperative to prevent reverse rotation of the roller.
