Improvements in Hot-water Apparatus for Heating Purposes.
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 to be as follows:-
This invention relates to hot water heating apparatus and manifolds therefor.
The invention consists first, in the peculiar construction of the heater or stove;
second in the construction of the manifold employed for conducting the water to
be heated in close proximity to the fire, and third, in the combination of the
various parts, as hereinafter described.
According to my said invention the apparatus which is made in sections comprises
a grate section which is preferably circular in form and upon which is mounted the
fire pot section, a proper joint being formed between the two parts; this fire pot
section is formed flaring being semicircular upon its ends, at the upper portion, and
straight at the sides, the sides and ends being preferably joined by round corners.
The combustion chamber is formed in two parts the lower part is substantially
rectangular in cross-section, and rests upon the top of the fire pot section, leaving
the two semicircular ends thereof exposed; the upper section of the combustion
chamber rests upon the top of the lower section but gradually narrows to a central
point in its longitudinal direction, thus forming a combustion chamber with a
closed top.
An outer casing is provided which is formed in two parts semicircular in cross-
section, and which rests upon the tops of the similarly formed ends of the fire pot
section, embracing the combustion chamber upon its longest sides, and uniting at
the top forming a magazine section which is provided with a top, and a feed door.
A door is provided in one of the exposed ends of the combustion chamber, and
a smoke exit is provided from the said chamber.
A manifold is arranged on an incline in the combustion chamber with the inlet
at the lower end and the outlet at the upper end at which points the manifold is
designed to be connected with a system of hot water circulating pipes.
This manifold consists of a number of small tubes communicating at each end
with the interior of the heads such heads being preferably provided with removable
caps diminishing towards the inlet and outlet respectively.
The parts being constructed and arranged substantially as herein described a fire
is made in the fire pot, fuel being put into the top of the magazine section, is fed
to the fire down upon two sides of the combustion chamber, and, as the manifold is
designed to take up the greater portion of the space in cross section of the
combustion chamber, the heat and products of combustion must necessarily pass up
between and envelope the pipes of the manifold before they can pass to the exit,
and it therefore follows that the water contained in the tubes of the manifold must
be heated to a high temperature and in its expansion it passes out of the manifold
at the top end and is replaced by cooler water Howing in at the bottom.
To prevent fuel feeding to the fire pot at the lower end of the manifold, the
lower section of the combustion chamber is provided with the downwardly projecting
wings which partially shuts off the feed and precludes the possibility of over-
heating or burning the manifold at that point.
The heads of the manifold, are preferably cast rectangular in form, from any
suitable metal, though I prefer brass; each of these heads is provided with a
well

page_text: Caps are designed to be bolted to the flanges of the heads suitable packing
being used so as to ensure tight joints between the parts; each cap being
provided with a threaded neck by means of which it may be readily connected
with any system of piping.
The pipes or tubes communicate with the wells of the heads and should preferably
be sufficient, to equal the bore of the neck.
To secure these tubes in place, which are preferably of copper, and to obtain
tight joints, I tap through the bottom of the well a number of threaded holes
equal to the number of tubes to be employed in the construction of the mani-
fold; the interior of the well is then tinned, the ends of the tubes are tinned
and inserted in the holes in the heads, their ends projecting slightly within the
well. I now by the use of a proper tool, expand the ends of the tubes till they
are firmly embedded in the threads of the holes. This being done the tubes
are temporarily plugged, and molten lead is poured into the well around the
ends of the tubes, thus forming a filling which firmly adheres to the tubes and
the walls and bottom of the well, and produces a thoroughly steam and water tight
joint between the parts.

Improvements in Hot-water Apparatus for Heating Purposes.
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 per-
formed, to be particularly described and ascertained in and by the following
statement :-
This invention relates to hot water heating apparatus and manifolds therefor.
The invention consists first, in the peculiar construction of the heater or stove;
second, in the construction of the manifold employed for conducting the water to be
heated in close proximity to the fire and third, in the combination of the various
parts, as hereinafter described.
In the accompanying drawings I have shown how my
veniently and advantageously carried into practice.
said invention may be con-
Figure 1 is a perspective view of the body of the improved heater, with the fire-
pot section and top section removed.
Figure 2 is a vertical central section of the heater, complete.
Figure 3 is a similar view at right angles to Figure 2, and also showing the
position of the manifold.
Figure 4 is a top plan of the fire-pot section.
Figure 5 is an enlarged sectional elevation of the manifold.
The apparatus constructed according to my said invention is made in sections.
A represents the grate section which is preferably circular in form and upon
which is mounted the fire-pot section B a proper joint being formed between the
two parts, this fire-pot section is formed flaring as shown being semicircular upon its
ends, at the upper portion, and straight at the sides, the sides and ends being
preferably joined by round corners.
C represents the combustion chamber, and it is formed in two parts a and b the
lower part a is substantially rectangular in cross section, and rests upon the top of
the fire-pot section, leaving the two semicircular ends thereof exposed as in
Figures 2 and 3, the upper part 6 or top section of the combustion chamber rests
upon the top of the lower section a but gradually narrows to a central point c, in
its longitudinal direction, thus forming a combustion chamber with a closed top.

page_text: D represents an outer casing which is also formed in two parts d and e, semi-
circular in cross section, and which rests upon the tops of the similarly formed ends
of the fire-pot section, embracing the combustion chamber upon its longest sides
and uniting at the top forming a magazine section which is provided with a top E.
and a feed door F.
A door G is provided in one of the exposed ends of the combustion chamber, and
an exit H is provided from the said chamber as shown. A manifold J is arranged
at an incline in the combustion chamber with the inlet at the lower end and the
outlet at the upper end i, at which points the manifold is designed to be connected
with a system of hot water circulating pipes.
This manifold consists of a number of small tubes; communicating at each end
with the interior of the heads K such heads being preferably provided with
removable caps L diminishing towards the inlet and outlet, as shown.
The parts being constructed and arranged substantially as herein described a fire
is made in the fire pot, fuel being put into the top of the magazine section, is fed to
the fire down upon two sides of the combustion chamber, and, as the manifold is
designed to take up the greater portion of the space in cross section of the com-
bustion chamber, the heat and products of combustion must necessarily pass up
between and envelop the pipes of the manifold before they can pass to the exit, at
H, and it therefore follows that the water contained in the tubes of the manifold
must be heated to a high temperature and in its expansion it passes out of the
manifold at the top end and is replaced by cooler water flowing in at the bottom.
To prevent fuel feeding to the fire pot at the lower end of the manifold, the
lower section a of the combustion chamber is provided with the downwardly
projecting wings m which partially shuts off the feed and precludes the possibility
of overheating or burning the manifold at that point.
A¹ represents the heads of the manifold, which are preferably cast rectangular in
form, from any suitable metal, though I prefer brass; each of these heads is.
provided with a well a'.
CC are caps which are designed to be bolted to the flanges of the heads A¹,
suitable packing being used so as to ensure tight joints between the parts each
cap being provided with a threaded neck D' by means of which it may be readily
connected with any system of piping.
B' represents a number of pipes or tubes which communicate with the wells a' of
the heads A', and should preferably be sufficient, to equal the bore of the
neck D¹.
To secure these tubes in place (which are preferably of copper) and to obtain
tight joints, 1 tap through the bottom of the well a number of threaded holes equal
to the number of tubes to be employed in the construction of the manifold; the
interior of the well is then tinned, the ends of the tubes are tinned and inserted in
the holes in the heads their ends projecting slightly within the well. I now, by the
use of a proper tool, expand the ends of the tubes till they are firmly embedded in
the threads of the holes. This being done the tubes are temporarily plugged, and
molten lead is poured into the well around the ends of the tubes, thus forming a
filling c which firmly adheres to the tubes and the walls and bottom of the well,
and produces a thoroughly steam and water tight joint between the parts.
Having now particularly described and ascertained the nature of this invention,
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 :-
First. A heating furnace comprising a combustion chamber with a closed top,
and a magazine section partially enclosing the said combustion chamber for feeding
fuel down upon two sides thereof, substantially as and for the purposes described.
Second. A heating furnace or stove, consisting of a grate section, a fire-pot
section and a combustion chamber partially enclosed within the magazine section,
in combination with a manifold consisting of a number of water conducting tubes
communicating with a manifold head at either end common to all of said tubes, the

page_text: parts being constructed, arranged and operating substantially in the manner and
for the purpose set forth.
Third. In a heater of the character described, a stove or furnace provided with
a combustion chamber, and a magazine section, in combination with a manifold
consisting of a number of tubes communicating to and with a head at either end,
the said manifold being placed in an inclined position wholly or partially within the
said combustion chamber and adapted to be connected to a system of hot water
circulating pipes, substantially as and for the purposes described.
Fourth. In a manifold, the heads A', having wells a¹ tinned upon the inside and
provided with threaded holes or openings in their bottoms to receive the tinned
ends of a number of tubes B', the ends of said tubes being tinned and expanded
into the said threaded holes, and a filling of lead c¹ surrounding the inwardly
projecting ends of said tubes, the parts being constructed and arranged substantially
in the manner and for the purposes specified.
Dated this 21st day of February 1891.
