The cam lifter feed mechanism of this invention comprises an inclined endless chain conveyor carried by an upper framework and a lower framework including a multiplicity 
of lug-like lumber engaging means mounted at intervals on the endless Motorbase chains of the conveyor, a driven shaft journaled for roatation in the upper framework including sprockets operatively engaged with endless chains of the conveyor, a plurality of cam lifters mounted on the shaft at opposite terminal sides of the endless chain conveyor including outwardly projecting hook-like foot portions being operable to engage the lowermost terminal edge of lumber continued the conveyor by the lug-like engaging means and to carry the lumber over the shaft to a point of discharge, a downwardly inclined discharge feed guide means mounted on the upper framework between cam lifters. The lower platform having a set of other hopper forming downwardly willing aspect framework users becoming operable to guide lumber toward the endless chain conveyor, means mounting the endless chain conveyor distally close to the lowermost end of the downwardly likely aspect framework member. The hook-like foot servings each have got a leading edge downwardly inclined with respect to the radii of the cam lifter at an angle coincident with the angle of inclination of the endless string conveyor, the foot part providing upwardly from the leading edge into a hook developing portion.
