Hydrocarbons.
We, WALTER MORSEBY CHINNERY of Bartholomew House, Dealer in Stocks and
PERCY TARBUTT of 23 St. Swithins Lane, Engineer, hoth in the City of London
do hereby declare the nature of this invention to be as follows:-
For combustion of liquid hydrocarbons apparatus has been employed such as is
described in the Specification No. 13752 of 1886. In this apparatus by admitting a
little air into the upper part of the vessel containing the hydrocarbon, partial
combustion is maintained therein and by directing a current of air through a nozzle
at the top of the vessel a vivid flame produced very complete combustion being thus
effected.
According to the present invention a reservoir which may contain a considerable
quantity of the hydrocarbon and which may be situated at a safe distance from the
combustion vessel, is connected therewith by a feed pipe provided with a cock or
valve which is opened when the apparatus is at work. The combustion vessel may be
divided by a horizontal partition into two compartments in which case the lower
compartment receives air forced into it under such pressure as is required, and from
this compartment there is a passage governed by an adjustable valve to an air nozzle
which opens in the centre of the upper compartment. The lower compartment may
however be dispensed with the compressed air being conducted merely by a pipe to
the nozzle. The vessel or its upper compartment receives its supply of the hydro-
carbon liquid from the reservoir the level of the liquid therein being maintained
approximately constant as in a fountain glass; that is to say, the reservoir being air
tight there is no flow of liquid from it to the combustion vessel unless the level in the
latter is so far lowered that air can pass along the feed pipe into the reservoir
permitting the outflow of a corresponding volume of the liquid. When the level of
the liquid in the combustion vessel is above the mouth of the feed pipe so as to seal it
against entrance of air, there is no farther supply of liquid until its level in the

page_text: combustion vessel is again lowered. Through the sides of the combustion vessel.
above the level of the liquid there are holes for admitting a small quantity of air to
maintain partial combustion within the vessel.
Above these holes the vessel tapers to a central outlet for the flame and the current
of air issuing from the central nozzle directs this flame upwards intensifying it and
effecting complete combustion.
The vessel becoming heated by the combustion, the hydrocarbon and the air are
heated before they mingle to produce the flame. In order to provide against
accidental leakage of air into the reservoir of hydrocarbon which would interfere with
the automatic action of the supply to the combustion vessel we have no opening in the
upper part of the reservoir but supply it by a siphon pipe descending to a level below
that of the combustion vessel and bending up to the reservoir.

Improvements in Apparatus for the Combustion of Liquid
Hydrocarbons.
We WALTER MORSEBY CHINNERY of Bartholomew House, Dealer in Stocks, and
PERCY TARBUTT of 23 St. Swithins Lane Engineer, both in the City of London 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 :-
For combustion of liquid hydrocarbons apparatus has been employed such as is
described in the Specification No. 13,752 of 1886. In this apparatus by admitting a
little air into the upper part of the vessel containing the hydrocarbon, partial
combustion is maintained therein and, by directing a current of air through a nozzle
at the top of the vessel a vivid flame is produced, very complete combustion being thus
effected.
According to the present invention, a reservoir which may contain a considerable
quantity of the hydrocarbon, and which may be situated at a safe distance from the
combustion vessel, is connected therewith by a feed pipe provided with a cock or valve
which is opened when the apparatus is at work.
The combustion vessel is divided by a horizontal partition into two compartments;
the lower compartment receives air forced into it under such pressure as is required,
and from this compartment there is a passage governed by an adjustable valve to an
air nozzle which opens in the centre of the upper compartment. The upper com-
partment receives its supply of the hydrocarbon liquid from the reservoir, the level of
the liquid therein being maintained approximately constant.
Through the sides of the combustion vessel above the level of the liquid there are
holes for admitting a small quantity of air to maintain partial combustion within the
vessel. Above these holes the vessel tapers to a central outlet for the flame and the
current of air issuing from the central nozzle directs this flame upwards, intensifying
it and effecting complete combustion. The vessel becoming heated by the
combustion, the hydrocarbon and the air are heated before they mingle to produce the
flame.
The accompanying drawing is a vertical section of the apparatus. The combustion
vessel is divided by the partition A into two compartments, the lower B which is
supplied with air under pressure by a pipe C leading from any suitable air com-
pressing apparatus, and the upper compartment D, which is supplied with oil from a
cistern E containing a float and cock or valve governing the supply by a pipe F leading
from an oil reservoir, which may be at a safe distance from the lamp. In the
centre of the partition A is screwed a nozzle G the lower mouth of which is
governed by a screw plug H, and the upper mouth of which projects a little
above the level of oil in the upper compartment. The cover K is of conical form
open at the top, and has a number of small holes k through it near its lower edge;

page_text: outside this cover is placed a hood L of size larger than K so that there is an
annular passage for air between it and K. The oil in the compartment D, being
kindled and supplied with a little air by the holes k, burns on the surface of the oil
with a lambent flame generating vapour and gases from the oil. The jet of air
through the nozzle G causes the combustible gaseous fluid mingled with air to rush
through the upper mouth of the cover K where it receives additional air ascending
within the hood L, the whole when kindled producing a high luminous flame. As
the cover K soon becomes heated, the combustible vapour and gases are generated
from the oil in larger quantity and are heated so that the lamp shortly attains its
maximum. illuminating power.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what l
claim is :-
Apparatus for the combustion of liquid hydrocarbons constructed and arranged
substantially as described with reference to the accompanying drawing.
