I, GEORGE SAMUEL SYMMONS trading as Prince and Symmons of Lion lamp works
Charlotte Street, Great Eastern Street in the County of Middlesex Lamp Manu-
facturer do hereby declare the nature of this invention to be as follows:-
The invention has for its object improvements in safety hydro-carbon lamps and
consists in means whereby a supply of air is caused to pass upwards at the sides of or
between the wick or wicks to keep the burner cool and whereby the oil is trapped
against passing to the light.
For this purpose I connect to the bottom of the container one or more air tubos the
lower end or ends of which is or are open to the atmosphere whilst the upper end or
ends rises or rise above the level of the top of the container. In combination with
the container provided with such air tube or tubes I employ burners which are fitted
with a tube or tubes telescopically fitting over the container air tube or tubes so as to
prevent the passage of oil through the space between or at the sides of the wicks to
the flame.
I also attach to the burner a tube which descends considerably into the container
and passes through and closely fits a suitable burner fitting carried by the container:
By this latter construction the burner is capable of being readily slidden into and out
of position in the container and the oil is effeciently trapped against passing out
through the burner fitting.

I, GEORGE SAMUEL SYMMONS trading as Prince and Symmons of Lion Lamp
Works, Charlotte Street, Great Eastern Street, in the County of Middlesex, Lamp
Manufacturer, 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:-
The invention has for its object improvements in safety hydro-carbon lamps and
consists in means whereby a supply of air is caused to pass upwards between the
wicks to keep the burners cool and whereby the oil is trapped against passing to
the light.
For this purpose I connect to the bottom of the container an air tube the lower end
of which is open to the atmosphere whilst the upper end rises above the level of the
top of the container. In combination with a container provided with such air tube
I employ a burner which is fitted with a tube telescopically fitting over the container
air tube so as to prevent the passage of oil through the space between the wicks to
the flames.
I also attach to the burner a tube which descends considerably into the container
and passes through and closely fits a suitable burner fitting carried by the container.
By this latter construction the burner is capable of being readily slidden into or out
of position in relation to the container and the oil is efficiently trapped against passing
out at the junction of the burner with its fitting.
And in order that the said invention may be more clearly understood and readily
carried into effect, I will proceed aided by the accompanying drawings more fully to
describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical section and Figure 2 is a sectional plan of a hydro-carbon
lamp illustrating my improvements.
a represents the oil container which according to my invention is furnished with a
plain or tapered air tube al, of oblong or other suitable cross section passing through
or connected with an opening formed in the bottom of the oil container a to which it
is secured by means of solder or otherwise. The lower end of this air tube a¹ is open
to the atmosphere and the upper end thereof rises above the level of the top of the
container a and thus stands well above the oil.
In combination with a container a provided with such an air tube a¹ I employ a
burner which is fitted with a short plain or tapered tube or sleeve b' telescopically
and closely fitting over the container air tube a' so as to prevent the passage of oil
or vapour through the space between the wicks to the flames.
The short tube 6' is entered into or connected with a hole formed in the plate or
partition 62 of the burner 6 where it is secured by means of solder or otherwise; and
the plate or partition 63 of the burner has an opening 6* formed therein in order to
allow air passing up the supply tube a¹ to have free access to the flames.

page_text: By these means 1 am enabled to keep the burner and adjacent parts much cooler
than heretofore and in consequence of the increased supply of air between the flames
I also obtain more complete combustion and a much whiter and more brilliant
light.
I also attach to the burner, preferably by soldering it thereto, a tube 6 which
descends considerably into the container a and passes through and closely fits a
suitable burner fitting a² carried by the container a. Or if desired the tube 65 may
be attached to the container and the base of the burner 6 or an extension thereof may
be formed to fit tightly therein as will be readily understood.
By these latter constructions the burner b is capable of being readily slidden into
or out of position in relation to the container a and the oil is at the same time
efficiently trapped against passing out at the junction of the burner with the
fitting a².
I would here remark that since filing my provisional specification I have discovered
that the method therein described of supplying air to the flame of a single wick burner
does not possess such an amount of utility as to render it desirable to make a claim
thereto and for this reason I have omitted to more fully describe and I do now hereby
disclaim such arrangement.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
:-
1. In a hydro-carbon lamp having two or more flat, or approximately flat, wicks,
the employment of an air tube, such as a to supply air between the flames in manner
substantially as heroin shown and described.
2. In a hydro-carbon lamp having two or more flat, or approximately flat, wicks,
forming the container a with an air supply tube, such as a' and the burner & with a
short tube or sleeve, such as ¹, in manner and for the purpose substantially as herein
shown and described.
3. In a hydro-carbon lamp having two or more flat, or approximately flat wicks the
combination of air supply tube a', short tube or sleeve 6, opening 6 in partition 6³,
and descending tube all in manner substantially as herein shown and described and
for the purpose stated.
