Invention of "AN IMPROVED METHOD OF UTILIZING THE VAPOUR OF
HYDROCARBON OILS OR THE PRODUCTS THEREOF OR SIMILAR SUBSTANCES FOR

COMPLETE SPECIFICATION filed by the said George Haseltine at the
Office of the Commissioners of Patents, with his Petition and
Declaration, on the 3rd December 1872, pursuant to the 9th Section
of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the International Patent Office, Southampton Buildings,
London, Doctor of Laws, send greeting.
WHEREAS I am in possession of an Invention for "AN IMPROVED
METHOD OF UTILIZING THE VAPOUR OF HYDROCARBON OILS OR THE PRODUCTS

page_text: THEREOF OR SIMILAR SUBSTANCES FOR OBTAINING MOTIVE POWER," and have
petitioned Her Majesty to grant unto me, my executors, administrators,
and assigns, Her Royal Letters Patent for the same, and have made
solemn Declaration that it has been communicated to me from abroad
by Perry Franklin Goodrich, of San Francisco, California, United States
of America.
NOW KNOW YE, that I, the said George Haseltine, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention, and
in what manner the same is to be performed, in and by the following
statement:-
My Invention relates to a new and economical method of converting
heat energy into mechanical force, and the said Invention consists in
operating engines or motors by a vapour produced from hydrocarbon
oils or the lighter products thereof, either separately or in conjunction
with other volatile materials instead of the steam ordinarily used for
such purpose.
The method of carrying the said Invention into practice is as
follows: I take a boiler of any suitable construction and place therein
a quantity of any of the lighter products of petroleum or analogous
hydrocarbon oil which are most easily volatilized or vapourized. To.
the boiler thus supplied heat is applied in any suitable manner to
convert its contents into a vapour, as water is converted into steam,
and this vapour I use to operate an engine or motor in the same
manner that steam is used for a similar purpose; but instead of
exhausting the vapour from the engine into the atmosphere and
allowing it to escape I exhaust it into a receiver or vessel of any
suitable kind, and then condense it again into a liquid form. The
liquid thus produced by the condensation of the vapour exhausted
from the engine is again pumped into the boiler where it is again
vapourized and used to operate the engine, and so on continuously.
.
In this way it will be seen that I use the same quantity of fluid over
and over; the same being first vapourized, then used to operate the
engine, then condensed and returned to the boiler to be again
vapourized.
It is obvious that the said Invention may be applied by means of
devices already well known and in use, and therefore I do not describo

page_text: any special mechanism for the purpose. The ordinary steam boiler and
engine will answer, it only being necessary to add a condenser and to be
sure that all the connections shall be perfectly tight and closed.
The exhaust vapour may be condensed by surrounding the receiver
with water or with air, especially if in the latter case the vapour is made
to pass for a considerable distance through pipes or tubes before it enters
the receiver from which it is to be returned to the boiler.
The advantages, of this method of generating power are very great;
in the first place, by using the lighter and more volatile products of
coal oil which vapourize at a lower temperature than water very little
fuel is required; in the second place the formation of scale in the
boiler and pipes is entirely prevented, and there is but little wear upon
the valves and other parts of the engine as the vapour and especially
any condensation thereof 'in the engine serves to lubricate the same.
Furthermore there will be no necessity for constantly furnishing the
boiler with a fresh supply of liquid, as when water is used.
In the case of ocean steamers this saving would be immense, for not
only would there be the actual saving in the cost of the fuel, but the
increased space for freight in consequence of having to carry less fuel
would be of great value. In locomotives this Invention would obviate
the necessity for stopping to take water, and I thus effect a saving of
time.
. While, as before stated, I prefer to use gasoline or the lighter
products of coal oil, I do not wish to be understood as limiting
myself to them, because it is obvious that the heavier grades may
be used in the same way, the only difference being that in the latter
case more fuel would be required and the saving therefore less, the
difference being simply one of degree and not of kind; and other
volatile substances of suitable nature may be used in connection with
the gasoline or light hydrocarbons. I sometimes use a quantity of
water in the boiler in connection with gasoline with good results; but
I prefer to use the gasoline without the water, or with but a small
portion of the latter, believing it to give the best results.
Having thus fully described the said Invention as communicated to
me by my foreign correspondent, and the manner of performing the
same, I wish it understood that I claim,-

page_text: First. The use of vapour produced from hydrocarbon oils or from the
products thereof, either separately or in conjunction with other volatile
substances, as herein set forth and for the purpose specified.
Second. Operating engines or motors by vapour generated from hydro-
carbon oils or the products thereof in a boiler, the said vapour, after it
has been used to operate the engine, being condensed and returned to
the boiler to be re-vapourized, and thus used continuously, substantially
as described.
In witness whereof, I, the said George Haseltine, have hereunto set
my hand and seal, this Third day of December, in the year of our
Lord One thousand eight hundred and seventy-two..
Witness,
