right angles to each other and tangent to the line of the centers. These
wheels carry on their periphery cavities that have the form of a quarter
of a sphere. They thus form at the point of contact a complete sphere
in which the material is inclosed. The paste is thrown by shovel, or
emptied by buckets and chain, into the hopper fixed at the upper part
of the frame. From here it is taken up by two helices, mounted on a
vertical shaft traversing the hopper, and forced toward the point where
the four moulding wheels meet. The driving pulley of the machine is
keyed upon a horizontal shaft which is provided with two endless screws
that actuate two gear-wheels, and these latter set in motion the four
moulding wheels by means of beveled pinions. The four moulding wheels
being accurately adjusted so that their cavities meet each other at
every revolution, carry along the paste furnished them by the hopper,
compress it powerfully on the four quarters, and, separating by a
further revolution, allow the finished ball to drop out.

The external crown of the wheels carrying the moulds consists of four
segments, which may be taken apart at will to be replaced by others when
worn.

This machine produces about 40 tons per day of this globular artificial
fuel.--_Annales Industrielles_.
