Improvements in the Construction of Gas Heating Stoves.
HENRY PATTMAN TRUEMAN of 3 St. Georges Terrace, Hockley, Birmingham
in the County of Warwick Engineer, and WILLIAM HARMER BRISCOE of
120 Branston Street Birmingham in the County of Warwick, Manufacturer do
hereby declare the nature of this invention to be as follows:-
Our improvements relate to that class of gas stove which is commonly used for
boiling purposes, and is usually detachably connected with the gas supply by a
flexible tube.
Our improvements consist in the shape and arrangement of the various parts
whereby effective combustion and economy of manufacture is secured. In carrying
our invention into effect, we form the body or air mixing chamber of the stove from
a wrought metal tube say of brass or iron. The supports are formed of two
wrought metal stampings which are shaped so as to form a seat for cooking utensils
at the upper part and feet for the stove at the lower part. One of the stampings
has a centre perforation, enabling it to be passed on to the aforesaid tubular body;
the other stamping is placed at, and closes the end of the mixing chamber. Long
rivets or screws connect the two stampings which are held apart by distance
pieces on the tubular body. The gas admission end of the tube is partially closed
by a wood handle; this handle is bored through from end to end and forms the gas
admission tube. The small jet pipe or nipple may be composed of a short brass
cap driven into the wood handle, but we prefer to use a pipe clay tube, which is
inserted into the wood handle. Suitable apertures are formed in the handle end of
the body for the admission of air. These air passages may be adjusted by a metal
collar or outer tube which can be turned round at will. The wood handle can also
be furnished with a gas tap to adjust the supply of gas. This tap consists of a hole
bored in the wood, at right angles to the supply bore.
Into this hole a metal or
hard wood plug is inserted, by turning which plug the gas supply may be adjusted
or entirely cut off.
The burner apertures may be made by drilling or punching holes in the tubular
body, but we prefer to use a helical coil of wire, so that the gas filters through the
spaces between the coils. In this case the upper portion of the tubular body is cut
away so as to expose the coils. The before named supports may be made of cast
metals if desired.

DESCRIPTION OF THE DRAWINGS.
Fig. 1 of the drawings shews the principal parts of our before described gas
heating stove in elevation. Fig. 2 shews a longitudinal section of the parts in
position, with a transverse section, taken on a centre line between C and B. Fig. 3
shews a plan of the gas heating stove; similar letters refer to the same parts
throughout the drawings which are made to a scale in which six inches equals one
foot. A Fig. 1 is the tube forming the body of the stove, one end is slit and
opened up as shewn. These wings form the distance pieces between the supports.
The shape of this portion of the tube is clearly shewn in the transverse section of
Fig. 2. B Fig. 1 is the support having a centre perforation, and C is the support
which closes one end of the tube A. Holes are formed in the supports for the
passage of the connecting parts as shewn in the drawings. D is the wood handle
which is bored through as shewn in the section Fig. 2. H is the pipe clay tube
inserted in the wood handle D. Fig. 2 shews a sectional view of the same parts in
position and connected together by the bolts F F and the stay G. E is the wire coil
forming the gas grating or burner apertures. At J Fig. 2 is shewn the regulating
tap (this tap is not shewn on Figs. 1 and 3) and at K is the air admission
aperture.
Fig. 3 shews a plan of all the aforesaid parts in their relative positions and marked
with similar letters. At C' and B' is shewn extensions at the upper part of the
supports, presenting a wide base to the vessels placed upon the stove. To construct
a gas stove according to this our invention; the parts B and C are placed in
position upon the tube A and secured by the bolts F. F. and stay G. The wire
coil F is placed in the open part of the tube. The handle D is placed at the other
end of the tube and secured, when the stove is complete.
We are aware that some of the parts above described are in themselves destitute
of novelty as forming part of a gas heating stove, but the shape, arrangement, and
connexion of the various parts as described constitute this our invention.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1st. In the construction of a gas heating stove, the employment of a tubular or

page_text: hollow mixing chamber provided with projections adapted to engage and hold in
position the supports, substantially as herein described.
2nd. In the construction of a gas heating stove the employment of a pair
of supports adapted to engage with projections on the tubular body as herein
described.
3rd. In the construction of a gas heating stove, the employment of a wood
handle bored so as to constitute a gas passage in itself, with or without a plug tap
as herein described.
4th. In a gas heating stove, the configuration and employment of a wood handle
adapted to form handle, tube nipple, and gas passage in itself substantially as herein
described.
5th. In the construction of a gas heating stove the configuration, arrangement.
and combination of the various parts, consisting of a tubular body, two supports,
wire coil, bored wood handle, stop cock, and pipe clay nozzle as and for the
purpose, herein before described.
