Abstract: A walking beam conveyor of the type having a plurality of reciprocally movable notched beams interposed between a plurality of fixed notched beams, cools and transfers elongated articles such as cylindrical bar stock between a furnace and a discharge station. Vertical and horizontal reciprocal motions are applied simultaneously to the movable beams by eccentrics which are mounted on a single drive shaft for advancing the bars along the fixed beams toward the discharge end of the cooling bed. The vertical motion eccentric is operatively connected to the movable beam through a bellcrank lever and the horizontal motion eccentric is connected by a generally horizontal push-pull connection. The beam notches are V-shaped with one sloped surface having a greater length and smaller angle of slope than the other sloped surface. Rotation of the drive shaft in one direction will reciprocate the movable beams causing the bars to rotate 90.degree.
