IMPROVEMENTS IN CONSTRUCTION OF STOVES OR HEATING APPARATUS
Year: 1884

page_text: PROVISIONAL SPECIFICATION:
I, JAMES STEPHENS, of Stonehouse, in the county of Gloucester, Engineer,
do hereby declare the nature, of my invention for IMPROVEMENTS IN
CONSTRUCTION OF STOVES OR HEATING APPARATUS to be as follows:-
THE
A novel mode of introducing water as the heating medium between the fire and
the air of the building or apartment to be heated, in a cheap and portable form, and
is an improvement on the well known "Gill Stove" (an apparatus which warms a
building or apartment by contact of the air with heated radial metal plates or
gills), and by which means I dispose of the objection to the "Gill Stove"
account of its liability to burn or over-beat the air of a building or apartment.
In carrying out my improvements I construct a metal case, or combustion
chamber: for containing the fuel, and fitted with fire grate, door, exit passage for
the waste gases, and ash pit.
on
This combustion chamber I enclose or partially enclose in another metal case, of
such size as to leave à space between it and the first named case or combustion
chamber; thus providing a chamber for the reception and heating of water, between
the two cases, called the water chamber.
To this outer case, and standing vertically outside of it, I attach a number of
hollow radial plates or gills by connecting their upper parts to the upper part of
the outer case, through which connections passages are formed from their interiors
to its interior, and also by connecting their lower parts to the lower part of the
outer case, through which conuections passages are formed from their interiors to
its interior. Thus providing the means for the rapid circulation of the heated
water from the water chamber and through the hollow radial plates, and for its
return to the water chamber to be again heated..
I fix a cistern either to the before named apparatus, or in any other position
seperate from it, at such a level that the lowest part of the cistern shall be above
the highest part of the outer case and of the hollow radial plates, and I conuect the
interior of the cistern to the interior of the outer case by a pipe from its lowest
part to the lowest part of the outer case.
I also connect the highest points of the interiors of the hollow radial plates to a
pipe common to all, which passes over the upper edge of the cistern.
This apparatus may be adapted for the combustion of gaseus fuel by fitting a
burner suitable for the combustion of gaseus fuel in the place of the before named
fire grate..

1, James StepheNS, of Stonehouse in the county of Gloucester, Engineer, do
heroby declare the nature of my invention for IMPROVEMENTS IN THE CON-
STRUCTION OF STOVES OR HEATING APPARATUS and in what manner the saine
is to be performed, to be particularly described and ascertained in and by the
following statement:―
A novel mode of-introducing water as the heating medium between the fire and
the air of the building or apartment to be heated, in a cheap and portable forïm,
and is an improvement on the well known "Gill Stove" (an apparatus which
warms a building or apartment by contact of the air with heated radial metal plates
.or gills), and by which means I dispose of the objection to the "Gill Stove" on
account of its liability to burn or over-heat the air of a building or apartment.

In carrying out my improvements I construct a notal case or combustion
chamber for containing the fuel, and fitted with fire grate, door, exit passage for
the waste gases, and ash pit.
This combustion chamber I onclose or partially enclose in another metal case, of
such size as to leave a space between it and the first named case or combustion
chamber. Thus providing a chamber for the reception and heating of water
between the two cases called the water chamber.
To this outer case and standing vertically outside of it, I attach a number of
bollow radial plates or gills, by connecting their upper parts to the upper parts of
the outer case, through which connections passages are formed from their interiors
to its interior, and also by connecting their lower parts to the lower part of the
outer case, through which connections passages are formed from their interiors.to
its interior. Thus providing the means for the rapid circulation of the.water from
the water chamber and through the hollow radial plates, and for its return to the
water chamber to be again heated..
I fix a cistern either to the before nained apparatus or in any other position
separate from it, at such a level that the lowest part of the cistern, shall be above
the highest part of the outer case and of the hollow. radial plates, and I connect
the interior of the cistern to the interior of the outer case by a pipe from its lowest
part to the lowest part of the outer case.. I also connect the highest points of the
interior of the hollow radial plates to a pipe common to all, which passes over
the upper edge of the cistern.. Or the last named pipe may be connected to the
highest point of the interior of the outer case and passed over the upper edge of
the cistern.

This apparatus may be adapted for the combustion of gaseus fuel by fitting a
burner suitable for the combustion of gaseus fuel in the place of the before named
fire grate.

A mode of carrying out my invention is shown by the accompanying drawings.
Fig 1 is a side elevation partly in section. Fig 2 is a transverse section on the
line A B in Fig 1. The letters refer to the same parts in each Fig.

page_text: C is the inner metal case or combustion chamber, D the fire grate, E the door,
F the exit passage for the waste gases, G the ash pit, H the outer case, I the space
between the inner and the outer case for the reception of the water to be heated,
K the hollow radial plates or gills, L the connecting passages from the interior of
the hollow radial plates to the interior of the outer case, through which the heated
water circulates, M the cistern for containing the supply of water, N the pipe for
the delivery of the water to the interior of the outer case, O the pipe for the
discharge of overflow water which may be caused by ebulition.
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 hollow radial plates or "water gills," attached to, or in combination with a
suitable vessel or boiler for heating water to circulate through them.
