ABSTRACT:
A lumber stacking apparatus is described for picking up a course of boards at a course pickup station and moving the course toward to a course stacking station over a stack and depositing the course on the stack. The apparatus includes a general frame having a carriage mounted thereon for reciprocating swinging movement between the two stations. The carriage is movably supported by parallelogram linkage. A crank drive is connected between the frame and the carriage for swinging the carriage back and forth between the station while maintaining the carriage horizontal. The swinging movement of the carriage converts potential energy of the carriage to kinetic energy during the initial portion of the forward and rearward strokes and converts kinetic energy of the moving carriage back to potential energy during the end of the strokes. Such a conversion drastically reduces the peak energy required to drive the carriage.
