HENRY HARRIS LAKE, of the Office of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "AN IMPROVED GASEOUS COMPOUND OR MIX-
TURE DESIGNED TO BE USED AS A MOTIVE POWER, WHICH INVENTION ALSO
COMPRISES PROCESSES OR METHODS FOR PRODUCING AND UTILISING THE SAID
COMPOUND." [A communication from abroad by Joseph Williams, of Sharpsburgh;
Edgar Smith, of Pittsburgh; and Joseph R. Milligan, of Wilkins, all in Pennsylvania,
United States of America.]
The said Invention relates, first, to a compound or mixture to be used as a motive
power for actuating a piston, which compound consists of the vapor of bi-sulphide
of carbon and petroleum oil; secondly, the method, hereinafter described, for pro-
ducing the said compound for actuating a piston, namely, injecting bi-sulphide of
carbon into a boiler supplied with petroleum oil previously heated; and, thirdly, to
the method of operating a piston, as hereinafter described, by supplying the cylinder
with a mixture composed of the vapor of bi-sulphide of carbon and petroleum oil,
and with a small quantity of liquid petroleum oil.
In carrying the said Invention into practice I employ a furnace, a steam-boiler, a
condenser, and a force pump, which is connected with the said boiler and condenser
by pipes, all of which parts are of the ordinary form and construction, and the
operation of which is well understood. I connect the boiler with the cylinder of an
engine by a pipe furnished with the usual throttle valve. The boiler is supplied

page_text: with petroleum oil or petroleum oil and water (preference being given to petroleum
oil), the boiler to be filled to the ordinary "water line."
The lighter or volatile portion of the petroleum oil must be evaporated for the
purpose of separating the gasoline and benzole from it prior to putting the petro-
leum oil in the boiler.
I then heat the petroleum oil or the petroleum oil and water in the boiler to
about two hundred degrees of heat, which should be indicated by a suitable
instrument.
I then charge the chamber of the condenser with bi-sulphide of carbon, then open
a valve so that the bi-sulphide of carbon will be forced by the said pump gradually
into the boiler, which, bi-sulphide coming in contact with the previously heated
petroleum oil or petroleum oil and water is rapidly vaporized, forming a force or
pressure in proportion to the quantity of bi-sulphide of carbon injected into the
boiler and the heat applied thereto. The boiler should be provided with a suitable
pressure-gauge for indicating the pressure in the boiler, and which will also enable
the operator to adjust the flow of the bi-sulphide of carbon. The desired pressure
being obtained, the vapor is allowed to pass through a pipe to the cylinder of the
engine for the purpose of actuating its piston, the exhaust of the engine communi-
cating by means of a pipe with another chamber of the condenser. The exhausted
vapor from the cylinder of the engine being condensed, is carried back again into
the boiler through the medium of the first named pipes and the pump, and worked
over again.
The cylinder of the engine must be supplied internally with a small quantity of
petroleum oil, also the steam chest and its valve or valves and the piston rod lubri-
cated with said oil.
A motive power formed by bringing bi-sulphide of carbon in contact with petro-
leum oil or petroleum oil and water, as herein before stated, will with a small
quantity of said oil in the cylinder of the engine operate the engine in all respects
as well as steam, the cost of the former as compared with the latter being at least
seventy five per cent. lower, and this motive power is equally as well controlled by
the engineer as steam. The petroleum oil is used for vaporizing the bi-sulphide of
carbon for the reason that it rapidly absorbs the heat of the fire, and thereby rapidly
vaporizes the bi-sulphide of carbon, the evolving of which atomizes a portion of the
petroleum oil, and the atoms commingle with the vapor, so that the latter acts as a
lubricant in the actuating of the piston for operating machinery.
I am aware that bi-sulphide of carbon gas has been experimented with for a
motive power in a great variety of ways, one example of which is described in the
Specification of Letters Patent granted to Alfred Vincent Newton, October 11th,
A.D. 1856, No. 2388. The present Invention or discovery, in contradistinction to
that described in the above named former Specification, will more fully appear by a
reference to the latter.
It will be seen that this Invention does not consist broadly in vaporizing bi-
Bulphide of carbon for a motor, or vaporizing it by water, fatty oils, or glycerine.

by the said Henry Harris Lake in the Great Seal Patent Office on the 2nd
October 1879.
HENRY HARRIS LAKE, of the Office of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "AN IMPROVED GASEOUS COMPOUND OR MIX-
TURE DESIGNED TO BE USED AS A MOTIVE-POWER, WHICH INVENTION ALSO
COMPRISES PROCESSES OR METHODS FOR PRODUCING AND UTILISING THE SAID
COMPOUND." A communication from abroad by Joseph Williams, of Sharpsburgh;
Edgar Smith, of Pittsburgh; and Joseph R. Milligan, of Wilkins, all in Pennsylvania,
United States of America.
The said Invention relates, first, to a compound or mixture which is to be used
for actuating a piston, and which consists of the vapor of bi-sulphide of carbon and
petroleum oil; secondly, to the method, hereinafter described, of producing a motor
for actuating a piston by injecting bi-sulphide of carbon into a boiler supplied with
petroleum oil previously heated; thirdly, to the method of operating a piston, as
hereinafter described, by supplying the cylinder with a mixture of the vapor of bi-
sulphide of carbon and petroleum oil, and with a small quantity of liquid petro-
leum oil.
The accompanying Drawing shews a perspective view partly in section of the
apparatus used for carrying the said Invention into practice.
A represents a furnace; B, a steam-boiler; C, a condenser; D, a force-pump,
which is connected with the boiler B and condenser C by pipes e and f, all of which
are of the ordinary form and construction, and the operation of which is well
understood. The boiler is connected with the cylinder of an engine by a pipe fur-
nished with the usual throttle-valve. The boiler B is supplied with petroleum oil
or petroleum oil and water (preference being given to petroleum oil), filling the
boiler to the ordinary "water line."
The lighter or volatile portion of the petroleum oil must be evaporated for the
purpose of separating the gasoline and benzole from it prior to putting the petro-
leum oil in the boiler B.
The petroleum oil or the petroleum oil and water in the boiler B must then be
heated to about two hundred degrees Fahrenheit, which should be indicated by
a suitable instrument. The chamber g of the condenser C is then charged with bi-
sulphide of carbon, and the valve h is opened, so that the bi-sulphide of carbon will
be forced by the pump D gradually into the boiler B, and coming in contact with
the previously heated petroleum oil or petroleum oil and water is rapidly vaporized,
generating a force or pressure in proportion to the quantity of bi-sulphide of carbon
injected into the boiler and the heat applied thereto. The boiler B should be pro-
vided with a suitable pressure-gauge for indicating the pressure in the said boiler,
and also for enabling the operator to adjust the flow of the bi-sulphide of carbon.
The desired pressure being obtained, the vapor is allowed to pass through a pipe i to
the cylinder of the engine for the purpose of actuating its piston, the exhaust of the
engine communicating by means of the pipe j with the chamber K of the con-
denser C. The exhausted vapor from the cylinder of the engine being condensed, is
carried back again into the boiler B through the medium of the pipes e, f, and pump
D, and worked over again.
The cylinder of the aforesaid engine must be supplied internally with a small
quantity of petroleum oil, the steam-chest and its valve or valves and the piston
rod being lubricated with such oil.
A motor produced by bringing bi-sulphide of carbon in contact with petroleum
oil or petroleum oil and water, as herein before stated, will with a small quantity of
the said oil in the cylinder of the engine operate the engine as well as steam, and
will be as easily controllable as steam, while its cost as compared with the latter
will be at least seventy five per cent. lower. The petroleum oil is used for vaporizing

page_text: the bi-sulphide of carbon for the reason that it rapidly absorbs the heat of the fire,
and thereby rapidly vaporizes the bi-sulphide of carbon, the evolving of which
atomizes a portion of the petroleum oil, and the atoms commingle with the vapor,
so that the latter acts as a lubricant in the actuating of the piston for operating
machinery.
Having thus fully described the said Invention as communicated to me by my
foreign correspondents, and the manner of performing the same, I wish it understood
that I am aware that bi-sulphide of carbon gas has been experimented with for a
motive power in a great variety of ways, one example of which is described in the
Specification of Letters Patent, dated October 11th, A.D. 1856, No. 2388, but the
present Invention differs materially from that described in the said Specification, as
will appear by a reference to the latter, and I wish it distinctly understood that I
do not claim broadly the vaporizing of bi-sulphide of carbon for a motor, or
vaporizing it by water, fatty oils, or glycerine, but I claim,-
First. The above described compound or mixture to be used for actuating a piston,
and consisting of the vapor of bi-sulphide of carbon and petroleum oil.
Second. The method, above described, of producing a motor for actuating a piston
by injecting bi-sulphide of carbon into a boiler supplied with petroleum oil pre-
viously heated.
Third. The method of operating a piston, as above described, by supplying the
cylinder of an engine with a mixture composed of the vapor of bi-sulphide of carbon
and petroleum oil, and with a small quantity of liquid petroleum oil.
In-witness whereof, I, the said Henry Harris Lake, have hereunto set my
hand and seal, this Second day of October, in the year of our Lord One
thousand eight hundred and seventy-nine.
HENRY H. LAKE. (L.S.)
