Abstract
An inclined chute is attachable to a support by means of a base including a clamping arrangement. An inclined base portion supports said chute and also a pair of bearing posts. A drum disposed within the chute is journaled within the bearing posts. Adjustment means enable axial positioning of the bearing posts for adjusting drum and chute clearance to accommodate various sized nuts. A handle imparts rotation to the drum.
