PROVISIONAL SPECIFICATION.
Improvements in Gas Stoves.
WILLIAM HOLDER Civil Engineer Caeran Park Newport Mon. I do hereby
declare the nature of this invention to be as follows:-
My invention relates to improvements in gas stoves, and has more particular
reference to heating rooms and buildings than for cooking purposes.
In carrying my invention into effect I construct my stove vertically for the
purpose of utilizing heat and lessening the space on which it stands, and consists of
two perpendicular tubes or cylinders the inner of which is made of fire clay and the
outer of any suitable material.
The inner cylinder is made in sections and has diagonal perforations at the
requisite distances for the reception of asbestos fibre.
These sections have suitable devices at both ends by which they are bound
together, thus forming a cylindrical pillar of flossy asbestos.
I construct the outer cylinder one inch or so larger in diameter than the inner
one and fix a suitable top to same for the reception of a kettle, or any other
purpose.
The base of my stove is so constructed as to receive the said cylinder and hold
same firm vertically.
The base is so formed as to allow a recess and hold the water necessary for the
easy withdrawal of the poisonous bye-products of combustion which accumulate
therein.
In the centre of the base I fix an atmospheric or other burner which communicates
directly with the centre of the asbestos lined inner tube at the bottom. The gas
when alight is retarded in its ascent by the asbestos fibre thus causing the latter to
become incandescent, consequently heating the fire clay tube on both sides at the
same time, first, by direct contact with the inside and by escaping at the top and
descending the outer tube (in the centre of which the former is fixed during which
process the bye-products of combustion are deposited in the water below which can
be readily extracted through a small tap which communicates with the water
chamber.
I leave small perforations at the bottom of the outer tube through which the
purified heated air escapes.

Improvements in Gas Stoves.
I WILLIAM HOLDER of Caeran Park Newport Monmouthshire do hereby
declare the nature of this invention and in what mauner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
My invention relates to improvements in gas stoves used more particularly for
heating purposes. In carrying my invention into practice I construct my stove
vertically for the purpose of utilizing heat and economizing space the same con-
sists of two vertical tubes or cylinders the innermost of which is made of fire clay
while the outer tube is made of any suitable material.
The inner tube or cylinder is made in sections and is furnished at suitable
intervals with diagonal perforations for the reception of asbestos fibres.

page_text: These sections have suitable devices at both ends by which they are bound
together thus forming a cylindrical pillar of flossy asbestos.
I construct the outer cylinder one inch or so larger in diameter than the inner
tube and fix in some cases a suitable top to the same whereon a kettle or any other
heating utensil may be conveniently placed. The base of niy stove is so constructed
as to receive the said cylinder and hold same firm vertically. The base is so
formed as to allow a recess and hold the water necessary for the easy withdrawal of
the poisonous bye-products of combustion which accumulate therein as the products
impinge on the surface of the water. In the centre of the base I fix an atmospheric
or other burner which communicates directly with the centre of the asbestos lined
inner tube at the bottom.
The gas when alight is retarded in its ascent by the asbestos fibre thus causing
the latter to become incandescent, consequently heating the fire clay tube on both
sides at the same time first by direct contact with the inside and by escaping at
the top and descending the outer tube (in the centre of which the former is fixed
during which process the bye-products of combustion are deposited in the water
below which can be readily extracted through a small tap which communicates with
the water chamber 1-leave small perforations at the bottom of the outer tube through
which the purified heated air escapes.
In the accompanying drawings
Fig. 1 is a vertical section of my improved gas stove and
Fig. 2 is a similar view of a modification of the same.
My improved gas stove consists of the outer tube or cylinder a of any suitable
material and of an inner cylinder b of fire clay this cylinder being preferably made
in sections bound together at each end and formed with diagonal perforations e for
the reception of the asbestos fibres d. The two cylinders are supported on a base e
forming a chamber for holding water f. g is an atmospheric or Bunsen burner
and is the gas supply pipe. i is a tap for drawing off the injurious and heavy
by-products of combustion, jj are holes in the inner and outer cylinders for lighting
purposes k. k. are holes near the bottom of the outer cylinder through which the
purified heated air escapes. The gas passing from the supply through the burner
is when alight retarded by the asbestos fibres thus heating the same and with it the
fire clay tubes on both sides first by direct contact and then by descending through
the outer tube the gas escaping through the holes k. The by-products of com-
bustion are deposited in the water e which can be readily drawn off through the
tap i.
In Fig. 2 the water receptacle is separate from the base and is formed of tin
or other suitable metal this receptacle having an annular or circular shape in plan
so as to fit between the inner and outer cylinders this modification is similar in con-
struction to that shown in Fig. 1.
Having now fully 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 :
:―
The improved gas stove arranged and constructed substantially as herein described
and shown and for the purpose set forth.
