Year: 1875

page_text: LETTERS PATENT to George Bryan Jennings, of No. 23, Philpot Lane,
in the City of London, for the Invention of "IMPROVEMENTS IN THE
USE OF COAL OIL AND OTHER OIL AS FUEL."-A communication from
abroad by Peter M. Qvist, of St. Paul, in the County of Ramsey, at
State of Minnesota, in the United States of America.
PROVISIONAL SPECIFICATION left by the said George Bryan Jennings
at the Office of the Commissioners of Patents, with his Petition, on
the 25th November 1875.
I, GEORGE BRYAN JENNINGS, of No. 23, Philpot Lane, in the City of
London, do hereby declare the nature of the said Invention for “Im-
PROVEMENTS IN THE USE OF COAL OIL AND OTHER OIL AS FUEL," to be as
follows:-
This Invention has for its object improvements in the use of coal oil
and other oil as fuel. For this purpose the oil is conducted by a pipe
from an elevated cistern into a tank containing water. The oil enters
amongst the water in the tank, floats to the surface of the water, and is

page_text: there burnt. The heat generated raises steam in a steam boiler or serves
for other manufacturing purpose for which furnaces burning coal or
other fuel are now employed.
Suitable valves are provided to regulate the flow of the oil, the level of
the water in the tank, and to prevent the water passing back into the
oil pipe.
TL
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Bryan Jennings in the Great Seal Patent
Office on the 24th May 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
BRYAN JENNINGS, of No. 23, Philpot Lane, in the City of London, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of November, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said George Bryan Jennings, Her
special license that I, the said George Bryan Jennings, my executors,
administrators, and assigns, or such others as I, the said George Bryan
Jennings, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN THE USE OF COAL OIL AND OTHER OIL AS FUEL," a com-
munication to me from abroad by Peter M. Qvist, of St. Paul, in the
County of Ramsey, at State of Minnesota, in the United States of
America, upon the condition (amongst others) that I, the said George
Bryan Jennings, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be

page_text: Figure 1 is a transverse section, and Figure 2 is a longitudinal section
of apparatus arranged according to my Invention.
a is a cistern containing the coal oil or other oil; a¹ is a coiled pipo
within the cistern to which steam may be admitted if necessary to keep
the oil fluid. is a tank containing water amongst which the oil can
be allowed to flow continuously and in regulated quantity by the pipe c,
on which is a stop-cock at d and a check valve at e to prevent the
possibility of a return flow. The oil floats to the surface of the water
up between the hollow trough-like bars through which air is admitted,
and the quantity of air may be regulated by a suitable damper or sliding
valve. The oil is ignited and burns at the surface of the water in the
tank; g is a pipe for supplying water to the tank b, and h is a draw off
pipe; i is a steam boiler in which steam is generated by the heat from

page_text: the furnace. Or in place of generating steam in a steam boiler the
furnace heat may be otherwise applied.
I claim the means substantially as described for the employment of
coal oil or other oil as fuel for generating steam or for other manu-
facturing purpose.
In witness whereof, I, the said George Bryan Jennings, have here-
unto set my hand and seal, this Twelfth day of May, in the
year of our Lord One thousand eight hundred and seventy-six.
