Improvements in Hot Water Heaters.
I, CHARLES ARTHUR ALLISON, of 52, Chancery Lane, London, in the County
of Middlesex, Patent Agent, do hereby declare the nature of this invention (which
has been communicated to me from abroad by Alva Hubbard, of 420, North
Calvert Street, in the City of Baltimore, State of Maryland, and United States
of America, Manufacturer), to be as follows:-
This invention relates to improvements in hot water heaters. The object of
the invention is to adapt a hot water heater to a fire place to heat the room
wherein it is located and also to heat any other room or rooms, as may be
desired, by means of pipes leading from the heater to the radiators located in the
room or rooms to be heated.
I carry out my invention by providing a heater formed of a number of hollow
sections fitted together one above the other and each section communicating
with the one next above it, by one or more passages.
These sections are fitted within the fire place and are provided with a fire
board in front so as to leave only the grate and combustion chamber exposed to
view.
The combustion chamber or fire box is formed by two or more sections so formed
as to extend back into the fire place leaving ample room for the fire. The
sections forming the combustion chamber or fire box are hollow and communicate
with the section next above. A grate is provided in the lowermost section for
the hot coals to rest upon.
The sections above the fire box are hollow on all four sides and are provided
with hollow transverse ribs which extend over the fire box or combustion
chamber. These hollow ribs have openings between them through which the
hot air from the fire below passes in its upward course.
The section at the top has a flat upper surface just above the transverse
hollow ribs. This surface is provided with an opening for the communication of
the chimney pipe through which the residue products of combustion are carried
off. This top section is also provided with one or more openings for the connec-
tion of the flow pipes which convey the hot water to the radiators in the room
or rooms to be heated.
All the sections above the fire box are arranged so that the hollow ribs of one
section are directly above the openings of the section next below. The trans-
verse hollow ribs of all the sections are directly above the fire box.
The operation of the device is as follows:
The water is supplied to the lowermost section from any suitable supply, and
passes up into the section next above filling the hollow ribs and then passes
into the next section and so on until it reaches the top section where it passes out
through the flow pipes and is conveyed to the radiators located in the room or
rooms to be heated and is then conveyed back to the heater and enters the
lowermost section and is again heated. The hot air from the fire around the

page_text: lower sections forming the fire box will heat the said sections and pass up through
the openings between the transverse hollow ribs heating the water therein and
passing out through the pipe at the top leading to the chimney.
It will be seen, that as the water heats it will begin to circulate and pass
through the several sections, out through the flow pipe at the top of the heater
and is conveyed to the radiators located in the room or rooms to be heated,
from thence it is conveyed back to the heater through pipes and enters at the
lowermost section, where it is reheated, passed through the several sections,
and over the same course as before. Thus it will be seen a continuous circula-
tion is created.
The several sections are secured together by any convenient means and are
provided with water-tight joints.
The heater when located in the room has the appearance of an ordinary grate
fire, the fire box only being exposed.

Improvements in Hot Water Heaters.
I, CHARLES ARTHUR ALLISON, of 52, Chancery Lane, London, in the County:
of Middlesex, Patent Agent, do hereby declare the nature of this invention (which
has been communicated to me from abroad by Alva Hubbard, of 420, North
Calvert Street, in the City of Baltimore, State of Maryland, and United States
of America, Manufacturer), 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 an improvement in hot water heaters. The object of
the invention is to adapt a hot-water heater to a fire place to heat the room
wherein it is located and also to heat any other room or rooms, as may be
desired, by means of pipes leading from the heater to the radiators located in the
said room or rooms to be heated.
Other features of the invention will be fully set forth in the description of
the accompanying drawing, in which,
Figure 1 is a front elevation of the complete heater, the fire-board being
shown by dotted lines.
Figure 2 is a vertical cross section of Figure 1, showing the wall line and
the mantel projecting from the wall.
Figure 3 is a plan view of the top section of the heater.
Figure 4 is a plan view of the intermediate sections of the heater, showing the
apertures between the transverse hollow ribs.
Figure 5 is a plan view of one of the sections that form the combustion
chamber.
Similar numerals refer to like and corresponding parts throughout the several
views.
In the accompanying drawing, 1, designates the hollow sections which form
the combustion chamber. These sections are hollow, as shown in Figure 2, and
communicate with each other through the apertures, 2. Connected to the lower
section on each side are pipes, 17, for supplying water to the heater, and which
also serve as return pipes, as will presently be described. Within the combustion
chamber, formed by the lower section, is a grate, 3, upon which the hot coals
rest.

page_text: The sections, 4, are placed above and extend across the combustion chamber,
and are hollow on all four sides thereof and provided with transverse hollow
ribs, 5, having apertures 6 between them through which the hot air from the
combustion chamber passes, as indicated by darts in Figure 2. These sections, 4,
also communicate with each other and with the sections, 1, forming the combus-
tion chamber, by means of the apertures, 2. These sections, 4, are so arranged
that the transverse hollow ribs, 5, of one section will rest above the apertures, 6,
of the section next below it. The sections, 4, are provided with transverse
hollow ribs, 5, in order that a large heating surface may be had. Between these
sections are openings, 7, to permit of cleaning between the said sections and
removing the dust that may accumulate there between.
The top section, 8, is flat and hollow and is provided with a hole, 9, to which
the smoke pipe, 10, is fitted. This top section, 8, is also provided with one or
more holes, 11, for the connection of the water or flow pipe or pipes, 12, which
carry the hot water, or steam, to the radiators.
The upper section, 8, and the two lower sections, 1, are provided with lugs, 13,
having holes, 14, therein through which the rods, 15, passes and secures the
sections together.
All the sections communicate and are provided with water-tight joints to
prevent leakage.
When the heater is located in a room it is set in the fire place and is provided
with a fire-board, 16, as shown in Figure 2, flush with the wall, which may be
ornamental so as to present a neat appearance. The whole device has the effect
of an open grate fire. The fire board, 16, is provided with a door, 19, to permit
cleaning between the sections forming the heater; also a door, 18, which opens
to the combustion chamber.
The operation of the device is as follows:
The water is supplied through the pipe, 17, to the lower section and passes
up into the sections above, filling the hollow transverse ribs,, 5, in the sections, 4,
and then flows out through the pipes, 12, connected to the top section, 8, to the
radiators located in the room or rooms to be heated. The hot air from the fire in
the combustion chamber heats the lower sections, 1, and passes up through the
apertures, 6, between the hollow ribs, 5, heating the water therein and then
passes out through the pipe, 10, at the top leading to the chimney.
It will be seen that as the water heats it will begin to circulate and flow
through the several sections, through the pipes, 12, at the top and pass to the
radiators located in the room or rooms to be heated, from then it is carried back
through pipes and enters the heater at the lower section through the pipes, 17.
Thus it will be seen a constant circulation of the hot water is continued and
the same water may be used over and over again.
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
1. In a fire-place heater, the combination of one or more hollow sections
forming a combustion chamber; one or more hollow sections placed above and
extending across the combustion chamber; a hollow section on top provided with
an aperture for the connection of the smoke pipe, and one or more connections
for flow pipes, all of said sections communicating; and a pipe connecting with
the lower section to supply water to the heater.
2. In a fire-place heater, the combination of one or more hollow sections
forming a combustion chamber; one or more hollow sections placed above and
extending across the combustion chamber and provided with transverse hollow
ribs and apertures therebetween; a hollow section on top provided with an
opening for the connection of the smoke pipe and one or more connections for
the flow pipe or pipes, all of said sections communicating; and one or more pipes

page_text: connected to the lower section to supply water to the heater and serve as return
pipes.
3. In a fire-place heater, the combination of one or more hollow sections
forming the combustion chamber; a supply and return pipes connecting with
the lower section; a grate within the lower section; one or more hollow sections
arranged above and extending across the combustion chamber and provided
with transverse hollow ribs and apertures therebetween; a hollow section on
top provided with a smoke pipe connection and connections for flow pipes, all
of said sections communicating; and a fire-board arranged in front of the
heater.
