The machine is wholly of cast iron. The frame consists of four
columns, A, bolted to a rectangular bed plate, A', and connected above
by a frame, B, that forms a table for the support of the transmission
pieces, as well as the iron ladders, _a_, and the platform, _b_, that
supports the water reservoirs, C, and sand receptacles, C'.

Between the two columns at the ends of the machine there are two
crosspieces, D and D', so arranged that they can move vertically, like
carriages. These pieces carry the axles of the pulleys, P and P',
around which the band saw, S, passes. In the center of the bed plate,
A', which is cast in two pieces connected by bolts, there are ties to
which are screwed iron rails, _e_, which form a railway over which the
platform car, E, carrying the stone is made to advance beneath the
saw.

The saw consists of an endless band of steel, either smooth or
provided with teeth that are spaced according to the nature of the
