Abstract
A device for adjusting or cocking an idler roll assembly so as to control the path of the belt in a conveyor belt system. A hook attached to at least one end of the idler roll assembly is hooked across a horizontal shaft having spacer structure, on top of a support stand, so that the idler roll assembly may be set at a desired angle with respect to the direction of travel of the belt and also may easily be adjusted. In one embodiment of the invention, the spacer structure include washers slidably mounted on the horizontal shaft with sufficient space left on the shaft to receive the hook.
