I SAMUEL BROWN of Alma Road Rotherham in the County of York Solicitor
do hereby declare the nature of my invention for IMPROVEMENTS IN GAS LAMPS
OR THE APPARATUS FOR GAS ILLUMINATION to be as follows:-
The present invention relates to an apparatus for improved illumination from
Gas for example-Make a Reflector of white or coloured porcelain, or glass,
enamelled Iron or other metal or material-The Reflector may be made in the
form of an inverted pyramid cone wedge-shaped or other figure having two or
more sides, having au internal inverted pyramid cone wedge-shaped or other figure
(as the case may be) having two or more sides, so arranged as to form a chamber
or receiver into which the gas may pass through the pipe in the ordinary way of
conveying gas or other fluids and from the said chamber the gas may be conveyed
to the burner or burners through a thin or narrow passage formed by leaving a
passage or space between the outer and inner pyramid cone wedge-shaped or other
figure having two or more sides -The Lamps or apparatus being used in Streets
Buildings or any other places.

I SAMUEL BROWN Alma Road, Rotherham in the County of York Solicitor do
hereby declare the nature of my invention for IMPROVEMENTS IN GAS LAMPS, OR
THE APPARATUS FOR GAS ILLUMINATIONS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement that is to say:-
My Invention relates to improvements in the construction of Gas Lamps, or
apparatus for illuminating by means of Gas, and has for its object to more fully
develop the illuminating powers of such gas and to reflect and diffuse the rays
light to the best advantage.
of
And in order that my invention may be clearly and fully understood I annex a
sheet of drawings to illustrate the same, in which the same letters of reference
indicate the same or similar parts in any of the figures.
Fig. 1. is a sectional elevation of a lamp made according to my invention.
Fig. 2, is a sectional plan of a three-side or triangular lamp.
Fig. 3, plan of a circular conical lamp.
,
In carrying my invention into practice in the construction of a lamp as shown
in Fig. 1 for an example, I form a receiver or heating chamber A, the outer
walls B B, consisting of one or more reflectors preferably extending from C to D,
and made of enamelled iron or other suitable material,
The receiver or heating chamber with the reflectors may be made of any suitable
configuration, preferably an inverted pyramid or cone; a corresponding figure or
shell of smaller size E, closed at the bottom and open at the top, is placed within
the receiver, so as to leave a narrow passage F, for gas between the outside of the
shell E, and the back of the reflectors B.
The inlet pipe G, is taken through the top plate of the receiver A, and carried
down towards the bottom of the shell E, and the burners H, are connected with
the lower part of the gas space F, and project to a suitable height in front of the
reflectors.
It will thus be seen that from the position of the burners, the gas when lighted
will rapidly heat the reflectors and from their large surface the heat will be imme-
diately transmitted to the thin body of gas contained in or passing through the
narrow passage F, to the burners; the result of this rapid superheating of the gas
just before its combustion, is to expand its bulk and cause it to burn with a
brilliant and pure flame.
As the receiver and the shell E become heated, the above described effect is
increased, by the gas having to rise from the bottom of the shell, to the top of the
receiver as indicated by the course of the arrows.
Instead of the burners being fixed at the base of the lamp, they may be fixed in
the face of the reflector, so as to draw the gas direct from the narrow passage F.
The receiver with the burners may if desirable, either for inside or outside
situations be enclosed in a glazed frame or lantern.

page_text: The reflectors and receiver may be made of any suitable material and shape but
I find that the most suitable angle for the reflectors is at seventy three degrees or
thereabouts; the supply pipe may also be passed into the receiver from below, as
would be the case in street lamps.
The passages F may be subdivided or contracted so as not to extend over the
whole area of the reflector as shown in the drawings.
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 Gas Lamps, or apparatus for gas illumination, the arrangement for
heating or superheating the gas before combustion, by the action of the flame from
the burners, substantially as herein before described and illustrated.
(2.) The construction of gas receivers for use in lamps, the outer walls of which
are used as reflectors and conductors of heat, for the purpose specified, and
substantially as herein before described and illustrated.
