ABSTRACT:
A mechanism for elevating and/or shifting a log infeed table to position a log received on the infeed table for a subsequent operation. The mechanism has sets of opposed paired crank arms pivotally mounted on supports. The infeed table is mounted on supporting shafts extending between the crank arms with the supporting shaft offset from the pivot axis of the crank arms. The crank arms are pivoted by an actuator coupled to a beam extended between one pair of the crank arms. All of the sets of paired crank arms have their beams coupled together by flexible couplings such that all of the sets of crank arms will pivot in unison. As the crank arms are pivoted by the actuator, the infeed table is raised or lowered. The supporting shafts are slidably movable in the cranks arms. Separate actuators are provided to move the supporting shaft in the crank arms to shift the infeed table transverse to the flow path of the infeed table.
