Weekly Chillicothe crisis. (Chillicothe, Livingston Co., Mo.) 1878-19??, 1880-04-22

| From the New York Graphic.
New York is threatened with another
motor which is destined ito revolutionize
trade and commerce" and many other
wonderful things. 1t has this advantage
over its Philadelphia predecessor that
there is nothing mysterious about it,
there remains nothing to be patented, and
any one may see all there is in it. Two
Pittsburg inventors, who in 1878 worked
out successfully an old idea which had
been tried for II hundred years, have taken
a warehouse at Rutgers and Cherry
streets, where they exhibited what they
call the mammoth motor" 1t consists
OF boilor and high.pressure engine, such
as are ordinarily used for steam, except
that they are of greater strength, with a
condenser and small iron tank, the lat
ter containing mixture of crude petro'
leum and bi-sulphide of carbon. The
vapor of bi-sulphide Of carbon has long
been experimental with as motive
power, but its great strength prevented 1t
from being used because of the difficulty
in controlling it. Its admixture with
petroleum, it is claimed, has obviated the
latter difficulty, and the inventors Of the
process say the experiments seem to con-
| firm The statement that while the power
can be Increased or diminished almost in
simultaneously, an assured pressure a
hundred per cent. greater than that OF
steam can be obtained at nominal cost.
The inventors are Mr.. Edgar Smith and
Mr. j. R. Milhgan, who have taken out
patents in this country, England, France,
Germany, Austria, Italy, Holland, Bel
gum, Spain. Australia and Canada. The
control of the American patent will, it is
understood, pass into the hands of New
York company, the head of which is Mr..
Henry +. Hamill, of the Delamater Iron
works. The patentees are Plttsburg
machinists, who have been carrying on
their experiments in that city unsuccess-
fully for several years. when, in 1873,
they succeeded in controlling the enormous
power which had previously been de-
veloped from the vapor by other expert
menters, and took out their patents.
The petroleum used is lubricating oil OF
600 degrees fire test, and water is mixed
with it and with the bi-sulphide of carbon.
The great economy results from the fact
that the latter, which is extremely cheap,
can be used over and over again, vaporizes
at extremely low temperatures, so that
little fire is needed, and the water in the
boiler need only be kept at any point
above 160 degrees. This can be done by
a light or stack fire. The vapor, instead
OF being blown off, passes into a con-
denscr,. seems instantly to resume its first
condition, and can be Immediately used
over again the same way as condensed
water is. A single pound of the material
costing ten cents, it is claimed, can be
used for an entire week, making it about
as costly as water, while only twenty-five
per cent. as much coal will be required in
keeping up the boiler heat as is necessary
for steam engines. Should this prove tC
be true, the advantage to ocean steamers
in the saving Of space and tonnage il
carrying coal as well as in the cost OF the
latter, will he enormous. The cost of the
small quantity cf coal oil used is repre-
sented as practically nothing
