The apparatus consists of a flat, cast iron, rectangular frame,
resting upon a wooden base which forms a closet. In a longitudinal
direction there is mounted on the machine a rectangular guide, along
which travel two iron slides in the shape of a reversed U, which make
part of two smaller carriers that are loaded with weights, and to
which are fixed cast-steel mullers.

At the center of the frame there is fixed a support which carries a
train of gear wheels which is set in motion by a pulley and belt.
These wheels serve to communicate a backward and forward motion,
longitudinally, to the mullers through the intermedium of a winch, and
a backward and forward motion transversely to two granite tables on
which is placed the ink or color to be ground. This last-named motion
is effected by means of a bevel pinion which is keyed to the same axle
as the large gear wheel, and which actuates a heart wheel--this latter
being adjusted in a horizontal frame which is itself connected to the
cast iron plate into which the tables are set.

This machine, which is 2 meters in length by 1 meter in width,
requires a one-third horse power to actuate it. It weighs altogether
about 800 kilogrammes.--_Annales Industrielles._
