IMPROVEMENTS IN SUN BURNERS
Year: 1884

page_text: I, CHARLES HUNT of Birmingham, in the County of Warwick, Civil Engineer, do
hereby declare the nature of my said Invention for "IMPROVEMENTS IN SUN
BURNERS" to be as follows:-
This Invention has for its object the more complete utilization of the light emitted
from the combustion of gas when consumed with the kind of appliances commonly
known as "sun-burners," in which a number of gas burners formed into several
groups are employed.
In the form of sun burner frequently made, each group of burners is placed
beneath a hollow truncated conical reflector, the heat and products of combustion
passing off through a tube connected to the top of the reflector, while the light is
reflected by the reflector into the apartment where it is most required. In this
form between each of the circular reflectors there is left a considerable space up
which rays of light pass and are to a great extent lost. The whole of the reflectors
are fixed beneath a truncated conical casing, the upper part of which communicates
with the air outside the apartment.
The Invention consists in making each of the reflectors hexagonal in plan,
instead of round as is usually done, and by this means covering a very much larger
area with reflecting surface, while at the same time any loss from the cause before-
mentioned is prevented, nearly the whole of the rays being reflected back into the
apartment. For the purpose of ventilation the combined groups are surrounded by
open work of cast iron through which the vitiated air of the room passes and keeps
the tubes connected to the reflectors comparatively cool.
COMPLETE SPECIFICATION.

I, CHARLES HUNT of Birmingham in the County of Warwick, Civil Engineer, do
hereby declare the nature of my Invention for "IMPROVEMENTS IN SUN-BURNERS
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement, reference being had to the
accompanying Drawings and to the letters and Figures marked thereon, that is
to say :-
This Invention has for its object the more complete utilization of the light emitted
from the combustion of gas when consumed with the kind of appliances commonly.

page_text: known as "sun-burners," in which a number of gas burners formed into several
groups are employed.
In the form of sun-burner frequently made, each group of burners is placed
beneath a hollow truncated conical reflector, the heat and products of combustion
passing off through a tube connected to the top of the reflector, while the light is
reflected by the reflector into the apartment where it is most required. In this
forin between each of the circular reflectors there is left a considerable space up
which rays of light pass and are to a great extent lost. The whole of the reflectors
are fixed beneath a truncated conical casing, the upper part of which communicates
with the air ontside the apartment.
The Invention consists in making each of the reflectors hexagonal in plan,
instead of round as is usually done, and by this means covering a very much larger
area with reflecting surface while at the same time any loss from the cause before-
mentioned is prevented, nearly the whole of the rays being reflected back into the
apartment. For the purpose of ventilation the combined groups are surrounded by
open work of cast iron, through which the vitiated air of the room passes and keeps
the tubes connected to the reflectors comparatively cool.
In order that the foregoing may be more easily understood Drawings are attached
hereto of which the following is a description. Fig. 1 is a plan of the under side
of a single hexagonal reflector with its group of burners A in the centre. Fig. 2 is
a plan of the under side of three such reflectors combined into one group, each
hexagonal reflector having its group of burners A.-Fig. 3 is a similar view of
seven reflectors formed into one group, each furnished with its respective group of
burners A. Fig. 4 is a general vertical sectional elevation showing the reflectors C,
the burners A and gas supply tubes B being in elevation.-D, D are the tubes for
conveying away the heat and products of combustion, and E in Figs. 2, 3 and 4
are spaces covered or partially covered with ornamental iron fretwork through
which the heated and vitiated air of the apartment pass up to the hood F Fig. 4 by
virtue of the draught caused by the ascension of the heated air and products of
combustion emanating from the gas when burning below. The heated and vitiated
air are conducted away from the hood F to the atmosphere outside the apartment
by a suitable conduit in the usual way. Beneath each reflector any suitable burner
or group of burners may be used instead of those shown in the Drawing.
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
The construction of "sun-burners" formed of three, seven or more hexagonal
reflectors combined in one group and provided with burners as herein described,
and as shown on the Drawings.
