Abstract
There is provided an improved hopper feed elevator utilizing an endless conveyor passing through a bin containing parts to be elevated. A curved tunnel is juxtaposed to an opening at the bottom of the bin. The endless conveyor passes through the curved tunnel. The endless conveyors includes a plurality of curved cleats which closely conform to the shape of the tunnel so as to avoid jamming of the apparatus by the parts. One wall of the tunnel may be formed as a spring loaded back plate so that the cross section of the tunnel is made variable.
