ABSTRACT:
A walking beam (20) is supported on and fixedly coupled to a pair of vertical rods (39) slidably received in bushings (41) mounted on a horizontally-movable carriage (40) held stationary in the absence of overriding force by a friction brake (60) coupled through a lost motion coupling (46, 48, 66) with a drive member 32 moved by an actuator 31 to undergo in alternation forward and reverse strokes. The rods (39) are pivotally coupled to the drive member (32) by inclined links (36). The arrangement is adapted to convert each forward and subsequent reverse stroke of the drive member into an up-forward-down-return rectangular movement of the beam (20).
