APPARATUS FOR MANUFACTURING GASEOUS OR AERATED BEVERAGES.


The apparatus employed at present for making gaseous beverages are
divided into two classes--intermittent apparatus based on chemical
compression, and continuous ones based on mechanical compression.

The first are simple in appearance and occupy small space, but their use
is attended with too great inconveniences and losses to allow them to be
employed in cases where the manufacture is of any extent, so the
continuous apparatus are more and more preferred by those engaged in the
industry.

Continuous apparatus, however, other than those that we now propose to
occupy ourselves with, are not without some defects, for the gas is
produced in them intermittingly and at intervals, and more rapidly than
