  • Patent number: 10414068
    Abstract: A tile or masonry saw assembly may include a saw, a frame, and a workpiece support. The saw includes a motor operable to turn a blade assembly to cut a workpiece. The frame is operably coupled to the saw to enable the saw to be moved along the frame in a first direction. The workpiece support is operably coupled to the frame to support the workpiece relative to the saw, and to allow the workpiece support to be moved along the frame. The saw assembly further includes a movement assembly via which both movement of the workpiece support and movement of the saw relative to the frame is accomplished, such that a movement of the work piece support along the frame in a second direction is enabled to cause the saw to move along the frame in the first direction which is opposite the second direction.
