ABSTRACT:
A stone block, cutting chain saw having an improved drive sprocket and chain link design is disclosed. The sprocket itself is formed using rectangular, preferably square, shaped teeth which engage corresponding receiving areas on the cutting chain. In the preferred embodiment, the teeth are formed of carbide steel. The sprocket having the improved teeth design is rotably attached to a drive shaft. The cutting chain continuously revolves around the drive sprocket and at least a second sprocket, so that rotary motion over both sprockets enables the continuous cutting of stone, rock, coal and the like.
