ABSTRACT:
An auxiliary drive is provided for a drive mechanism for a conveyor, the mechanism including a brake and clutch arrangement designed to facilitate the starting and stopping of the conveyor. The auxiliary drive is conveniently mounted on the mechanism and has a drive motor driving a gear through an intermediate pinion, a gear wheel fixed to the driven stage of the mechanism. The intermediate pinion is movable to engage both the gear wheel and gear to transmit drive from the motor to the driven stage but is actuable to discontinue such drive. The auxiliary drive is intended to provide a means whereby the driven stage may be run at a speed lower than its normal operating speed, a particular application being to conveyors of the scraper chain type which at times require tensioning or detensioning of the chain for maintenance purposes, but at speeds lower than can be achieved using the main drive motor.
