We may, therefore, at once proceed to introduce to our readers the
apparatus of this class illustrated in the above engravings. This is
a hoist (Cherry's patent) manufactured by Messrs. Tangye Brothers, of

the flexible steel rack connected to the piston, F, and gearing with a
toothed wheel, B, which is inclosed in a watertight casing having cover,
