Improvements in Apparatus for Heating Buildings and the like.
1, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, do hereby
declare the nature of this invention to be as follows:-
This invention relates to a water heater for heating buildings and the like in
which a water heating chamber is arranged to surround a combustion chamber and
a portion of a fire pot, if desired, and in which, also, the water chamber is extended
across the combustion chamber by so shaping or forming the inner shell of the
heater as to provide a narrow hollow partial partition extending from the back of
the combustion chamber below the escape port upwardly and inwardly to near the
top of the combustion chamber, the cavity whereof is connected at the bottom and
at the sides with the water heating chamber.
This hollow partition serves to largely increase the water heating capacity of
the heater, in that it increases the area subjected to the action of the products of
combustion, and in that it is arranged to receive the direct impact therefrom
and then to deflect them to the front of the heater, causing them to traverse the
entire inner side of the heater at the front to the top, and then downward upon the
opposite side of the partition and the opposite side of the combustion chamber to
the escape port. The water heating chamber is supplied through one or more
inlets near its bottom and the heated water leaves the heating chamber at
its top.

1mprovements in Apparatus for Heating Buildings and the like.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 relates to a water-beater for heating buildings and the like, in
which the water-heating chamber is arranged to surround the combustion-chamber
and, if desired, a portion of the fire-pot, and in which, also, the water-chamber is
extended across the combustion-chamber by so shaping or forming the inner shell
of the heater as to provide a narrow hollow partial partition extending from the
back of the combustion-chamber below the escape-port upwardly and inwardly to
near the top of the combustion-chamber, the cavity whereof is connected at the

page_text: bottom and at the sides with the water-heating-chamber. This hollow partition
serves to largely increase the water-heating capacity of the heater, in that it
increases the area subjected to the action of the products of combustion, and in
that it is arranged to receive the direct impact therefrom and then to deflect them
to the front of the heater, causing them to traverse the entire inner side of the
heater at the front to the top and then downward upon the opposite side of the
partition and the opposite side of the combustion chamber to the escape port.
In the accompanying drawings,
Figure 1 is a side elevation of a heater constructed according to my invention.
Figure 2 is a vertical central section thereof.
Figure 3 is a vertical section on the line az of Figure 2, and
Figure 4 is an horizontal section on the line of Figure 2.
A is the ash-pit; B is the fire-pot; and C the combustion chamber. The lower
part of the fire-pot is preferably lined with fire-brick b. The upper part of the
fire-pot and the combustion-chamber C and the water-heating chamber or
cavity D, D are preferably formed by one casting, which rests upon the ring
and above the fire-brick b. In this casting is provided the fire-pot opening E,
adapted to be closed by a door, and also the escape-port El, to which the chimney
is attached. The said casting is preferably formed slightly conical from its base
upwards to its rounded top, the inner shell c and the outer shell c¹ being united
at their bottoms at c but the sides of the shells are separated from each other so as
to form an annular cavity or space entirely surrounding the combustion-chamber
and preferably a part of the fire-pot, the said annular space forming the water-
heating chamber D. The inner shell e has extending inward from the back part
of the combustion-chamber, below the escape-port E', a hollow section or partition c³,
which extends forward and upward in the combustion-chamber and also to the sides
of the shell, and the cavity of which forms the water-heating section D', which
is connected at its bottom d and at its sides with the main water-heating chamber.
The upper edge d' of this partition extends very nearly to the top of the com-
bustion-chamber, and it is curved from its centre upwardly in each direction,
(see Figure 3), and the connection between its cavity or water-heating chamber Di
and the chamber D extends from the sides to the point d. (See Figure 3.) This
hollow partition greatly increases the water-heating capacity of the heater by
increasing the area subjected to the action of the products of combustion.
It provides a water-heating chamber where it will receive the greatest amount of
heat, and also upon both its sides by receiving the first impact of the heat and
then deflecting and guiding it so that it is thrown against the front of the com-
bustion-chamber and caused to take an upward course about the top and downward
against the back side of the combustion-chamber and against the rear wall of the
partition to the escape port.
It will be understood that the water-heating chamber is supplied through the
inlet F or any other suitable place or places, and that the heated water leaves the
heating-chamber by the pipe F¹, extending from the top of the heater; and it will
also be seen that the water-heating chamber D extends almost vertically towards
the outlet F', and that the water-heating chamber D' is also substantially vertical,
and that where the chambers D and D¹ are not vertical the friction upon the
passing water is reduced as much as possible by curving such parts of the chamber
in the direction of the flow of the water, one object of my invention being to
interpose as little friction or resistance to the rapid flow of the water through the
heater as possible.
While it is desirable to extend the water-heating chamber into the fire-pot,
nevertheless the former may begin above the fire-pot. The connection between
the water-beating chamber D1 and the chamber D may be made from the centre
of the top of the hollow partition to the top of the water heating chamber D
directly, and this connection may be used instead of the side connections as shown
in the drawings or in conjunction with the said side connections, as may be desired;
and consider that my invention would be practised in part if the partition c³ were

page_text: solid instead of hollow, as certain of the beneficial effects of this invention
be thereby obtained, and in such case the said partition would be cast integral with
the inner plate c, or it could be made separate and attached thereto.
It will be understood that a constant circulation of water is maintained through
the heater, the distributing pipe system (not shown in the drawings) and by the
return pipe back to the heater.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
1. The combination in a hot water heater of the inlet pipe F, the water-
chamber D, conical in shape, and surrounding the combustion chamber, the water
chamber Di extending almost vertically from the lower part of the combustion
chamber below the escape port E to the upper part thereof, connected at its
sides with the water chamber D, and the outlet F1, substantially as described and
for the purposes specified.
2. The combination in a hot water heater of the water chamber D surrounding
the fire-pot and combustion chamber, and the water chamber D' extending from the
lower back portion of the combustion chamber to the upper central portion thereof,
connected with the water chamber D at the sides, and having a curved top,.
substantially as described and for the purposes specified.
3. The combination in a hot water heater of the water chamber D, conical in.
shape and the water chamber D₁ extending vertically through the combustion
chamber and cast integral therewith, substantially as described and for the
purposes specified.
4. A hot water heater provided with a combustion chamber enclosed by a water
heating chamber preferably somewhat conical, and having one or more water
inlets at its bottom and one or more outlets at its top, and a water heating chamber
in the combustion chamber extending across the same from side to side and from
below the escape port, connecting with the main water heating chamber, and the
walls of which form a dividing and deflecting partition in the combustion
chamber.
