Improvements in Apparatus for Heating Water or other Fluids.
We, JOHN CUMMING, of Bonella, Butlers Deane Road, Wallingham, Bath Proprietor,
FRANCIS NICHOLAS FENNELL, of Somerset Villa, Whytecliffe Road, Purley and GEORGE
FREDERICK FENNELL, of Marion Villa, Whytecliffe Road, Purley, both Clerks, and all
in the County of Surrey, do hereby declare the nature of this invention to be as
follows:-
The said invention relates to apparatus for heating water or other fluids for
warming buildings or conservatories or other purposes, and it is designed to effect
same in an advantageous and economical manner, by an apparatus which shall occupy
a small space, requiring no special setting, and which shall practically obviate any
danger of collection of sediment or fouling, and which shall utilize the whole of the
heat of the furnace employed.
Our invention consists of an inner furnace case, and an outer case surrounding the
same, so that the whole of the heat of the furnace is utilized against a comparatively
thin film of water or other liquid to be heated. The furnace is fitted with a suitable
draught pipe and stoke hole, as also with a damper to regulate the draught, and a
suitable flue is provided to carry away the waste products of combustion. The outer
or reservoir case has an inlet flow at the lower part, and an outer flow at the upper
and hottest part, and where a system of heating, such for instance as would be
suitable in a conservatory, is in question, the flow of the heated liquid is very rapid,
and the temperature is consequently well sustained. Where it is a question of
heating a quantity of water, (for baths for instance), we place in the circuit of flow a
cistern or tank, through which the heated water flows and the contents of which are
soon raised to any necessary temperature. In the bottom of the outer case we
provide a sluice tap to withdraw any sediment which may be deposited from the

page_text: contained liquid, and we may also provide suitable doors to admit of a scraper being
introduced if necessary.
Where it is intended to heat liquids other than water, such for example as the
chemically prepared liquids used in the warming pans for railway carriages, we may
carry our heated liquid in a pipe through a reservoir of such fluid.
In the furnace we suitably hinge the fire bar frame and place it in a sloping
position, so as easily to move and cast off the ash.
We may also jacket the whole apparatus with any suitable non-conducting com-
position, to lessen the radiation of the heat.

Improvements in Apparatus for Heating Water or other Fluids.
We, JOHN CUMMING, of Bonella, Butlers Deane Road, Wallingham, Bath Proprietor,
FRANCIS NICHOLAS FENNELL, of Somerset Villa, Whytecliffe Road, Purley, and
GEORGE FREDERICK FENNELL, of Marion Villa, Whytecliffe Road, Purley, both
Clerks, and all in the County of Surrey, 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 :-
The said invention relates to apparatus for heating water or other fluids for warming
buildings or conservatories, or other purposes, and it is designed to effect the same in
an advantageous and economical manner, by an apparatus which shall occupy a small
space, requiring no special setting, and which shall practically obviate any danger of
collection of sediment or fouling, and which shall utilize the whole of the heat of the
furnace employed.
In order that our invention may be the better understood, we now proceed to
describe the same in relation to the drawings hereunto annexed, reference being had
to the letters and figures marked thereon. Like letters refer to like parts throughout
the figures.
Figure 1 is an elevation of our device partly broken away so as to show internal
arrangements.
Figure 2 is a sectional elevation of the same.
Figure 3 is an alternative arrangement of rectangular form, shown also in sectional
elevation.
Our invention consists of an inner furnace case A and an outer case B surrounding
the same, so that the whole of the heat of the furnace is utilized against a com-
paratively thin film of water or other liquid to be heated. The furnace is fitted with
a suitable draught pipe and stoke hole D, as also with a damper E to regulate the
draught; and a suitable flue F is provided to carry away the waste products of
combustion. The outer or reservoir case has an inlet flow at the lower part and
an outer flow M at the upper and hottest part. Where a system of heating, such for
instance as would be suitable for a conservatory, is in question, the flow of the heated
liquid is very rapid, and the temperature is consequently well sustained. Where it is
a question of heating a quantity of water, for baths for instance, we may place in the
circuit of flow a cistern or tank through which the current of heated water flows, and
the contents of which are soon raised to any necessary temperature. In the bottom of
the outer case we provide a suitable sluice tap to withdraw any sediment, which may
be deposited from the contained liquid, and we may also provide suitable doors K to
admit of the scraper being introduced if necessary.
Where it is intended to heat liquids other than water such for example as the
chemically prepared liquids used in the warming pans of railway carriages, we may
carry our heated liquid in a pipe through a reservoir of such Huid, thus avoiding
direct contact, whilst at the saine time raising the temperaturo.

page_text: In the furnace we suitably hinge the fire bar frame L, and place it in a sloping
position, so as easily to move and cast off the ash. In figure 2 the fire bar frame is
shown pivotted at the centre and in figure 3 pivoited at the end.
We may jacket the whole apparatus with any suitable non conducting composition
to lessen the radiation of the heat, and, in order to prevent incrustation, we may
galvanize the interior of the water casing.
Although we have shown our apparatus in a cylindrical form, yet it is obvious it
might be constructed in a square or other form.
our said
Having now particularly described and ascertained the nature of
invention and in what manner the same is to be performed, we declare that what we
claim is :-
The construction of apparatus for heating water or other fluids consisting of a
double casing exposing the water in a comparatively thin film to a central furnace,
and provided with sluice taps, tilting fire bars and subsidiary devices, substantially as
and for the purposes specified.
