Abstract: A motorized saw assembly includes a base assembly having a workpiece support surface which defines a workpiece surface plane, an upper support assembly configured to support a saw blade, and a hinge assembly including a first linkage assembly and a second linkage assembly. The upper support assembly is configured to move between a first position, whereat the first linkage assembly and the second linkage assembly extend substantially perpendicular to the workpiece surface plane, and a second position, whereat the first linkage assembly and the second linkage assembly extend over the workpiece support surface.

Abstract: The multiple saw machine includes a rigid mainframe that provides mountings and attachments for all mechanical components. The components include multiple saw frames, conveyor belts, transfer chains and drive shafts for providing motive power for the conveyor belts, saw blades and transfer chains. A computer and an array of sensors are employed to monitor the saw machine functions and to control the timing of and location of board cutting.
