Complete Specification Left, 10th Oct.. 1898-Accepted, 19th Nov., 1898
Improved Oil Injector for Water Gas Carburetters.
We, CHARLES FREDERIC BOTLEY, of Gas Works, Hastings, in the County of Sussex,
Engineer, and SAMUEL CUTLER, Junior, of Providence Iron Works, Millwall, in the
County of London, Engineer, do hereby declare the nature of this invention to be as
follows:-
In the manufacture of carburetted water gas the oil used for carburetting the gas
is injected into highly heated chambers and therein volatilized, and to secure the
greatest efficiency the oil should be minutely atomized and sprayed uniformly
within the chamber and not permitted to impinge in any considerable quantity upon
the heated brickwork, as this causes local cooling and defective gasification.
By our invention the volatization of the oil is effected in a most complete manner
and the maximum enrichment imparted to the gas.
In carrying out our invention, we conduct the oil, which is preferably preheated,
into a chamber wherein it is subjected to a considerable pressure of steam, air or gas,
and is ejected therefrom through an exit tube and passing forward to the atomizer
encounters there a jet of steam, compressed air, or gas, and is caused to enter the
carburetter in the form of a fine spray. We prefer to use in conjunction with this
device the form of atomizer described in Patent 9316 of 1896, but may substitute any
equivalent device suitable for the purpose.
Dated this 10th day of January 1898.

Improved Oil Injector for Water Gas Carburetters.
We, CHARLES FREDERIC BOTLEY, of Gas Works, Hastings, in the County of Sussex,
Engineer, and SAMUEL CUTLER, Junior, of Providence Iron Works, Millwall, in the
County of London, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
In the manufacture of carburetted water gas the oil used for carburetting the gas is
injected into highly heated chambers and therein volatilized, and to secure the
greatest efficiency the oil should be minutely atomized and distributed uniformly
within the chamber and not permitted to impinge in any considerable quantity upon
the heated brickwork, as this causes local cooling and defective gasification. By our
invention the volatilization of the oil is effected in a most complete manner and the
maximum enrichment imparted to the gas.
Referring to the illustrative drawing hereunto annexed which represents an

page_text: arrangement of apparatus for carrying out our invention, oil, preferably preheated, is
conducted through a suitable pipe d into a reservoir b wherein it is subjected to
a considerable pressure of steam, air, or other gas supplied from the chamber c
through pipe g. The said chamber c is supplied from any convenient source, the
pressure therein being regulated by a suitable controlling valve ; in the supply
pipe h.
The oil under pressure in the reservoir b is forced through pipe e to the
atomizer and, encountering there a jet of steam, air or other gas coming from
chamber c through pipe f, is broken up and enters the carburetter a in the form
of a finely divided spray.
We prefer to use in conjunction with this device the form of atomizer described
in Patent 9316 of 1896, but may substitute any equivalent device suitable for
the purpose.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is-
1. An improved oil injector for water gas carburetters comprising an atomizer
communicating with the carburetter, an oil reservoir in communication with the
said atomizer and into which the oil is conveyed and subjected to pressure and a
pressure chamber in communication with the said oil reservoir and also with the
said atomizer, the whole substantially as described.
2. The combination of a gas carburetter with an atomizer communicating with
the said carburetter, an oil reservoir in communication with the said atomizer and
into which the oil is conveyed and subjected to pressure and a pressure chamber in
communication with the said oil reservoir and also with the said atomizer, the whole
arranged, constructed and operating substantially as described and shown."
