PROVISIONAL SPECIFICATION.
Improvements in Burners and Apparatus for Lighting Fires.
CHARLES EDWARD HALL of Meersbrook Bank Sheffield in the County of
York Engineer do hereby declare the nature of this invention to be as follows:-
For Improvements in Burners and Apparatus for Lighting Fires.
Firstly. In the construction of gas tubes or lighters and their application for
igniting fuel; such burners may be of any convenient shape either flat, circular,
oval, tubular, conical, or a combination of the above; and of attaching them at
one end by a suitable metallic coupling of any well known kind to a flexible tube
which is connected with the ordinary gas service at the other end. The burner
has air ducts or passages so arrauged in relation to the gas supply (which issues
in the form of a jet) causing an induced draft which mixes in the burner and is
projected into the fireplace.
When it is desired to light a fire with my improved apparatus; the said flexible
tube is coupled to the gas supply & the burner is placed between the bars of the
fireplace and lighted; coal or other fuel is built over it until ignition takes place
when it is withdrawn and used for another fire.
The said gas & air flame may be further excited by the addition of a hand or
foot bellows of any suitable kind such as an india rubber cone or pear shaped ball
which will supply the mixture under pressure & expedite the process of fire
lighting.
Secondly. Of constructing the fire-grate bars hollow with suitable perforations
(protected from dirt & ashes) for discharging the mixed gas & air (ignited)
amongst the fuel. Suitable couplings are provided on the fire grate for attaching
a flexible or fixed gas tube thereto.
Thirdly. Of constructing fire lighting tubes or blocks or burners so that they
may be placed within any fire grate and by means of piping and suitable couplings
connect them to the fixed gas service in every room so that any fire may be readily
lighted by turning on the supply of gas and applying a light. A collapsible air
vessel with a check valve may be placed on the gas supply pipe to increase the
pressure and expedite the operation.

COMPLETE SPECIFICATION.
Improvements in Burners and Apparatus for Lighting Fires.
CHARLES EDWARD HALL of Meersbrook Bank Sheffield in the County of
York 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:-
For Improvements in Burners and Apparatus for Lighting Fires, and,
Firstly. In the construction of portable metallic gas and air tubes or lighters,
and in their application for igniting fuel. The precise form of such lighters may
vary, but I have shewn several types at Figs. 1. 2. 3. 4. 5 and 6. which will
5 and
sufficiently indicate the nature of my said invention.

page_text: Secondly. In the construction of hollow firebars with a covering plate, removeable
for cleaning purposes, such hollow firebars to be placed within the firegrate or
furnace, but removeable therefrom and connected by a flexible metallic tube to the
gas service as illustrated by Figs. 7. 8.9 and 10.
Thirdly. In the construction of fixed hollow grates or bars, built into the fire-
place or furnace and connected by a permanent arrangement of pipes to the gas
service; and in making hollow blocks or dead plates, with suitable gas and air
ducts cast therein as shewn at Figs. 15. 16. 19 and 20.
Any of the above forms of firelighters may be used in conjunction with asbestos
lumps when so required.
In order to make my said invention clear, I have attached a sheet of drawing
fully illustrating the same.
Fig. 1 is a vertical section of the gas and air chamber of a portable fire
lighter. Fig. 2. is a sectional plan of same.
Fig. 3. is a vertical section and Fig. 4 is an end elevation.
Fig. 5. is a plan of a flat circular firelighter suited to stoves and the like.
Fig. 6. is a vertical tubular lighter in section, which may be used for lighting
fires in small stoves or for heating goffer irons and the like.
The same letters refer to the same parts in the portable firelighters which are
used with flexible metallic or india rubber tubes.
A is the principal box tube or frame of the lighter. B. is the gas tube or gas
nipple for attaching the flexible tube to and may have a wood or other handle E.
threaded thereon. This nipple may be cast with A. or inserted therein as shewn.
C is a detachable cover secured by screws D. in the small bosses cast on A.
F is the air supply tube through which air is drawn by the action of the gas
jet b. d are gas and air jet ports, whose openings are protected from dust and
ashes by the overhanging edges of the cover C.
Figs. 7. 8. 9. 10. 11 and 12. illustrate the second part of my said invention as
applied to firegrates and furnaces.
Fig. 7. is a front elevation
Fig. 8 plan with cover N removed.
Fig. 9, also a front elevation, with separate gas and air ducts.
Fig. 10 plan with cover n removed.
Fig. 11.,sectional elevation, and Fig. 12 transverse section of fire-grates to suit
different types of furnaces.
Any of these may be placed upon the existing firebars and grates. M. is the
main casting with the gas and air channels and outlets cast therein. N is a cover
secured thereto by screws. O are the openings between bars for ashes. P. air
and gas channels. d, gas and air jet ports. H. hole for inserting the combined gas
jet and air injector, shewn in detail at Figs. 13 and 14.
I. separate air duct or passage joining H, where a simple gas nipple only is
used instead of the compound nipple 13 and 14.
Figs. 15. 16. 19 and 20 illustrate the third part of my said invention as applied
to fixed firegrates and furnaces for permanent work.
Fig. 15 is a vertical section of a circular burner for placing under a boiler or
other apparatus and Fig. 16 is a plan partly in section of the same.
I is the main casting [' is the annular air and gas mixing chamber. K is the
cast iron cover. H. is the gas jet. L. air ducts. d gas and air jet ports.
Fig. 19. is a longitudinal section of a hollow bar for lighting boiler and other
furnace fires; and Fig. 20 is a cross section.
I is the main tube casting or block. K is the compound gas and air jet d are the
outlet ports.
To increase the draught or force the fires when lighting, air under pressure may
be admitted along with the gas in any well known manner.
Figs. 17 and 18 illustrate a gas burner for heating box irons. Fig. 17 is a
longitudinal section, and Fig. 18 is a plan partly in section.
A is the main frame B is the gas supply tube. C. the cover, d gas jets.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
0
Firstly. Constructing portable metallic gas firelighters as described and illustrated
at Figs. 1. 2. 3. 4. 5. 6.
Secondly. Constructing hollow fire bars and grates with a covering plate so as
to act as an ordinary grate and firelighter combined or gas fire if required sub-
stantially as described and illustrated at Figs. 7. 8. 9. 10. 11. 12.
Thirdly. Constructing hollow grates bars or blocks to be fixed or built into the
fireplace or furnace substantially as described with reference to Figs. 6. 7. 8. 10.
