Slate-saw.

A machine for trimming the edges of slate-slabs to shape. In the example, the slab is laid on a traversing bed and passes beneath two circular saws which are gaged such a distance apart as the proportions of the slab may warrant or the width of the piece required may justify-The blades are made of diameters from 2 feet up to 13 feet, and the machine is used for other varieties of stone beside slate.
