We, ROBERT WARNER and SAMUEL BENJAMIN GOSLIN of The Crescent Foundry
Jewin Crescent in the City of London Engineers do hereby declare the nature of
this invention to be as follows :-
--
This invention has for its object improvements in heating apparatus for water and
air and for these purposes we make the water boilers of circulating hot water heating
apparatus either circular or by preference of an elongated oval form either with oval or
circular furnace tubes with or without one or more cross circulating tubes placed
vertically horizontally or at angles inside the main furnace tube with a terminal end
water space connected to the inner and outer shells or tubes-the outer shell being
provided with angle iron seatings attached horizontally to form with metal plates or
tiles or bricks placed thereon-side flues distinct and apart and free from the boiler
plates. We also mount the boiler upon cast iron standards for the same purpose and
to form a space for the bottom return flue, the arrangement of the flues and access
thereto by soot doors together with a regulating damper door under the furnace bars
effecting economical consumption of fuel.
When a terminal end is provided we take circular side flues from the inner to the
outer shell near the back end and divert the smoke or heated gases into side flues
leading to the front and then into a flue leading along the bottom of the boiler to its
back end and in cases where it is advantageous to heat air in combination we provide
cast iron saddle gills with flues running through the sides of them in connection with
the side flues of the water boiler and provide proper dampers regulators and soot doors
as in the former case. We also provide water troughs to admit of the heated air
being moistened where required and encase the heating apparatus in a concrete or
brick formed chamber.
The furnace flue may be placed centrally within the boiler shell or above the
centre so that the main heating of the water takes place near the upper part of the
boiler.
We do not however confine ourselves to the exact placement of the inner flue tube
it may be arranged for a larger or less water space under over or at the sides of
the fire when applied to baths laundries or lavatories or to conservatories greenhouses
rooms or halls.

page_text: We, ROBERT WARNER and SAMUEL BENJAMIN GOSLIN of The Crescent Foundry,
Jewin Crescent in the City of London, Engineers, 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:-
This invention has for its object improvements in heating apparatus for water and
air and for these purposes we make the water boilers of circulating hot water heating
apparatus either circular or by preference of an elongated oval form either with oval
or circular furnace tubes with or without one or more cross circulating tubes placed
vertically horizontally or at angles inside the main furnace tube with a terminal end
water space connected to the inner and outer shells or tubes-the outer shell being
provided with angle iron seatings attached horizontally to form with metal plates or
tiles or bricks placed thereon-side flues distinct and apart and free from the boiler
plates. We also mount the boiler upon cast iron standards for the same purpose and
to form a space for the bottom return flue, the arrangement of the flues and access
thereto by soot doors together with a regulating damper door under the furnace
bars effecting economical consumption of fuel.
When a terminal end is provided we take circular side flues from the inner to the
outer shell near the back end and divert the smoke or heated gases into side flues
leading to the front and then into a flue leading along the bottom of the boiler to its
back end and in cases where it is advantageous to heat air in combination we provide
cast iron saddle gills with flues running through the sides of them in connection with
the side flues of the water boiler and provide proper dampers regulators and soot
doors as in the former case. We also provide water troughs to admit of the heated
air being moistened where required and encase the heating apparatus in a concrete or
brick formed chamber.
The furnace flue may be placed centrally within the boiler shell or above the
centre so that the main heating of the water takes place near the upper part of the
⚫ boiler.
We do not however confine ourselves to the exact placement of the inner flue tube
it may be arranged for a larger or less water space under over or at the sides of the
fire when applied to baths laundries or lavatories or to conservatories greenhouses
rooms or halls.
Figure 1 is a transverse vertical section Figure 2 a longitudinal vertical section
Figure 3 a front view and Figure 4 a horizontal section of one form of. boiler for
hot water circulating apparatus constructed according to our invention.
A is the inner furnace tube B the terminal end water space-C C passages at each
side from the inner end of the furnace tube to the outer sides of the boiler-D D are
angle iron seatings secured along the two sides of the boiler shell-the angle irons
have plates D fixed to them which form the bottom of side return flues E-tiles,
bricks or metal plates may be placed above the plates D¹ to protect them-F is a cast

page_text: iron plate forming a standard to support the front end of the boiler and G a cast iron
plate to support it at the back. The space H below the bottom of the boiler is closed
at the front by the plate F and door F' and at the back there is an opening Gi
through the plate G by which this space communicates with a flue I led upwards past
the back end of the boiler to a chimney J. K is a door to give access to the back
end of the boiler and chimney. L L are mud hole covers at the front end of the
boiler F¹ is a soot hole door at the front end of the bottom flue H. M M are soot
hole doors at the front end of the side flues. N is a furnace bridge at the back end
of the fire. O is the flow pipe leading from the top of the boiler and P the return
pipe opening into the bottom of the boiler. The heated gases from the fire after
passing over the bridge pass from the inner furnace tube through the passages C C to
the side flues E and at the front end of these flues they descend into the bottom
flue H and from the back end of this flue to the flue I leading to the chimney.
Figure 5 is a longitudinal section, Figure 6 a transverse section and Figure 7 a
front view of a modification of the boiler and its stand. In this modification the side
flues are omitted and the heated gases from the fire after passing over the bridge pass
directly into the bottom flue H through a passage formed through the bottom of the
boiler at the back end of the inner furnace tube A and 'from the flue H to the
chimney. In this construction also the bridge is formed as a hollow water bridge.
The bottom flue H is formed entirely within the casting upon which the boiler rests so
that no brickwork flues have to be formed when setting the boiler.
Figure 8 is a front elevation. Figure 9 a side elevation, Figure 10 a longitudinal
section, Figure 11 a section on the line A B, Figure 12 a section on the line C D
and Figure 13 a section on the line E F of the terminal ended boiler used together
with air heating appliances.
In these figures the parts which are like those shown in figures 1, 2, 3 and 4 are
marked with the same letters of reference. The side flues E are formed of passages
through the lower part of cast iron saddle gill plates R where these plates are formed
to abut one against the other. The gill plates are surrounded by an air chamber S to
which cold air is admitted through an inlet T and from which heated air passes by an
outlet V. W W are auxiliary air inlets for regulating the heat of the outgoing air.
XX are flues for distributing the incoming air to the spaces between the plates R.
Y Y are slots formed through the foundation plates to admit of the passage of the
air to the spaces between the plates. Z Z are troughs which may be kept filled with
water to supply moisture to the heated air.
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 :-
1. A boiler with flow and return pipes for hot water heating apparatus and formed
with an inner furnace flue and terminal end water space and side or bottom outlets
from the inner furnace flue near its back end beyond the furnace bridge.
2. The construction of water heating apparatus substantially as herein before
described and shewn at Figures 1, 2, 3 and 4.
3. The construction of water heating apparatus substantially as herein before
described and shewn at Figures 5, 6 and 7.
4. The construction of water and air heating apparatus substantially as herein before
described and shewn at Figures 8, 9, 10, 11, 12 and 13.
