ABSTRACT:
Apparatus for feeding pieces of lumber along a path with the center lines of the pieces extending along a preselected datum plane in the direction of the path. A plurality of spaced apart, upper and lower transverse members are mounted for rotation about horizontal axes at opposite sides of the datum plane with the lower side of each upper transverse member and the upper side of each lower transverse member traveling in the direction of the path of movement of the lumber to provide oppositely disposed transverse members at opposite sides of the datum plane. Outwardly projecting lumber engaging members carried by the oppositely disposed transverse members are yieldably urged toward the adjacent sides of the pieces of lumber therebetween with substantially equal force to maintain the center line of the pieces of lumber along the preselected datum plane.
