Abstract: A method for treating the surfaces and edges of a block to mimic the appearance of natural stone. The apparatus and method can treat up to four sides of a block, can be adjusted to provide varying degrees of surface and edge treatment, and useful in high volume block production equipment. Blocks are produced having a natural, weathered appearance without the damage, breakage, dust, or expense associated with conventional splitting and tumbling methods.

Abstract: A concrete block splitter including an anti-backdrive holding blade, a rigid cutting table, and a lower cutting blade. The present invention provides a masonry splitter that splits blocks or bricks starting from the bottom side of the block, which typically includes the most dense material, so that a resultant fracture propagates along a uniform plane through the block. The anti-backdrive holding blade firmly clamps the block onto the rigid table during a splitting operation in such a manner that the blade does not move relative to the rigid table. Accordingly, during a splitting operation, the block is prevented from moving and the blade is prevented from deflecting. The cutting blade contacts the bottom surface of the block with sufficient force to propagate a fracture through the block. In the preferred embodiment, the splitter is mounted on self-powered wheels for easy installation and removal from an automated block production line.
