ABSTRACT:
Apparatus for cutting elongate workpieces, such as lengths of lumber including lengths of scrap lumber, into blocks of predetermined length for use, for example, as spacers for pallets, the apparatus comprising a chute for holding a workpiece generally vertical comprising separate upper and lower portions, a generally horizontal circular saw blade, a pivotally mounted arm carrying the saw blade for moving the saw blade between a cutting position in which the saw blade extends between the chute portions for cutting the workpiece and a retracted position in which the saw blade is spaced from the chute, and a feed mechanism for feeding the workpiece through the chute under the force of gravity in timed relation to the movement of the arm. The feed mechanism comprises upper and lower clamps for releasably clamping the workpiece in the upper and lower chute portions, respectively, a stop movable between a workpiece supporting position in the lower chute portion for supporting the workpiece with its lower end spaced a predetermined distance below the cutting plane and a block releasing position in which the stop is spaced from the chute to allow a block cut from the workpiece to drop from the chute, and control mechanisms operatively associated with the arm and the upper and lower clamps and the stop for controlling the operation of these latter elements in timed relation to the movement of the arm.
