ABSTRACT:
The present invention is directed to a portable, table-type masonry saw for cutting concrete blocks, bricks, marble, tile, stone and other objects. The masonry saw includes a gasoline engine for driving a saw blade through a belt drive arrangement coupled to an arbor shaft on which the blade rotates. The gasoline engine is mounted on a stationary support while the saw blade is pivotally mounted by means of a live pivot shaft for engagement and disengagement with the workpiece. A water trough and pump are provided for wet-cutting. The water pump is connected to an output shaft of the gasoline engine through a belt drive which may be removed to permit dry-cutting of an object.
