Abstract

The saw has two or more arms spaced apart and solidly secured together, each arm acting as a support for a chain equipped with cutting tools. The design combines light weight and consequent easy handling with deep penetration into the rock, working face etc. Any rock between the chains and not actually cut by them is sufficiently thin and brittle to be broken up and removed with the remainder of the spoil during the cutting operation. The arms are held apart by spacer blocks which have tapped holes receiving screws joining the arms to the blocks.
