The cam lifter feed mechanism of this invention comprises an inclined endless chain conveyor carried by an upper framework and a lesser framework including a multiplicity of lug-like lumber engaging means mounted at intervals on the endless 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 Bearing plurality of cam lifters mounted on the shaft at opposite terminal sides of the endless chain conveyor including outwardly projecting hook-like foot portions becoming operable to activate the lowermost terminal edge of lumber continued the conveyor by the lug-like engaging means and also to carry the lumber over the shaft to a spot of discharge, a downwardly inclined discharge feed guide means mounted on the upper framework between cam lifters. The low framework having a pair of other hopper developing downwardly inclined aspect frame members getting operable to guide lumber toward the unlimited chain conveyor, means installation the endless string conveyor distally close to the lowermost end of the downwardly willing aspect body member. The hook-like foot portions 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 issuing upwardly from the leading edge into a connect developing portion.
