Chicago eagle. [volume] (Chicago, Ill.) 1889-19??, 1893-12-02

In 1780-S3 Henry Cayendish, of
England, made the surprisingly im-
portant and valuable discovery that
Xater was composed of one-third
4ygen, by volume, and two-thirds
hydrogen. These gases burn with
intense heat when brought together
and ignited, producing water as the
ashes of such combustion. Previous
to this time water had been con
sidered one of the primary and in
Invisible elements of the universe
the universal solvent, and that only
After this discovery of Cavendish
search began to be made for the
util ization of the discovery for
the manufacture Of cheap il
Illuminating and fuel gas, as shown
~ the invaluable records of the
United States and foreign patent
Offices 1t was not, however until
1876 that the first plant for the man
ufacture and distribution of illumi-
mating water gas was put to use in
New York City by the construction
of the Municipal Gas Works, operat-
ing what is known as the TeSsie du
Motay system. The primitive and
Tasteful process was soon after i'm
kroved by the invention and intro
duction of the Lowe system. since
which time the Lowe system has been
modified by various inventors, name
ly: Granger, Springer, FlannerH
Martin, Moses, Humphreys, Mckay
Critchlow, Hanlon < Leadley, Pratt
& Ryan. and others These methods
have superseded the primitive retort
or coal gas processes in most of the
large cities of this country.
All Of the foregoing systems men
tlnned for the manufacture Of illu-
ninating water gas are confined to
the use of costly anthracite coal or
its equivalent, coke. How to handle
cheap bituminous coal economically
and without waste so as to convert it
completely into gas and ashes by the
water gas process has, until now,
been an unsolved problem since the
discovery of Cayendish This prob
lem has at last been completely and
satisfactorily solved and the process
by which it is accomplished has been
put to use by the National Gas and
Water Company, 218 La Sale street,
to manufacture high candle power
gas for the Cicero Gas Company,
which supplies gas to the suburban
villages of Austin. Ridgeland and

The process and apparatus is the
invention of Mr.. Henry c. Rev.
citizen of Chicago and has been de-
yeloped by Mr. Il. +. Morrell,
water-gas engineer of national repu-
tation.
The coal is first quickly cooked in
internally fired coling chambers hay-
ing independent air supplies. The
coke then drops into adjoining gem
orators, wherein the carbon contained
i'm ii is completely combined with
the oxygen of the air while heating
no and with the oxygen OF the steam
while making gas, Nothing is left
: but the ash and clinker
