PROVISIONAL SPECIFICATION.
Improvements in and relating to Fire Grates.
We, JAMES DANIEL HANNAH of 20 Victoria Street, Castle Fields, Shrewsbury,
Inventor, and WILLIAM CHARLES CLEMENT PEELE 11, High Street Shrewsbury,
Gentleman do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in and relating to fire grates, and the
object of our invention is to construct a fire grate by means of which a larger
portion of the heat from the fire will be utilized for warming the room or chamber
in which it is situated, and consequently less heat is allowed to escape to waste up
the chimney, than in the case with fire grates of the hitherto usual construction.
In carrying out our invention we provide the back, and preferably also the sides
of a grate, with a suitably constructed air chamber, the form of sail chamber being
such that the fire in the grate rests against said air chamber so that the air within
said chamber is heated.
At suitable positions at the upper part of said air chamber, we provide one or
more radiating pipes into which the heated air escapes. Said radiating pipes,
which are preferably formed with suitable perforations, may extend any desired
necessary distance around the room, and the lower portion of the air chamber is
formed with suitable openings to allow ingress of cold air into said chamber, the
arrangement of the whole being such that the heated air passes up into the
radiating pipes, through the perforations in which radiating pipes, said heated air
escapes into the room, while at the same time the supply of air in the chamber is
replenished through the openings at the lower part of said chamber as described.
It is found that if the air in the room or chamber in which our improved
apparatus is being used, be permitted to enter the chamber at the lower openings
referred to, said air becomes unduly warm and dry by reason of its constantly
circulating through the hot air chamber, to obviate which we cause the said lower
openings in the chamber to communicate with say, the air or atmosphere outside of
the building or with any other air supply so that a constant supply and circulation
of altogether fresh air through the heating chamber into the room takes place.
We wish it to be understood that we do not confine ourselves to any particular
construction of the different parts constituting our invention nor to any material of
which said parts may be made. We prefer also to provide the hot air chamber
with shelves or partitions of such a construction and disposition as to compel the
air, while circulating and being heated in said chamber, to travel in a more or less
circuitous path therethrough so that said air will be exposed to a larger heating
surface than it would if merely allowed to pass directly through said chamber into
the radiating pipes the current of air is also thereby increased.
We prefer also to provide the radiating pipes as well as the lower or supply
openings with suitable taps or cocks, so that the amount of air admitted into the
room or into the chamber or equivalent may be regulated.
We may attach to the ends of the radiating pipes any disinfectant for purifying
the atmosphere, which is sometimes essential, for example in hospitals or for
sick rooms.

We, JAMES DANIEL HANNAH 20 Victoria Street, Shrewsbury, Inventor, and
WILLIAM CHARLES CLEMENT PEELE 11 High Street Shrewsbury, Gentleman
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 improvements in and relating to fire grates, and the
object of my invention is to construct a fire grate by means of which a larger
portion of the heat from the fire will be utilized for warning the room or chamber
in which it is situated and consequently less heat is allowed to escape to waste up
the chimney, than in the case with fire grates of the hitherto usual construction.
In carrying out my invention I provide the back and preferably also the sides of
a grate, with a suitably constructed air chamber, the form of said chamber being
such that the fire in the grate rests against said air chamber so that the air within
said chamber is heated.
At suitable positions at the upper part of said air chamber, I provide one or
more radiating pipes into which the heated air escapes, said radiating pipes,
which are preferably formed with suitable perforations, may extend any desired
necessary distance around the room, and the lower portion of the air chamber is
formed with suitable openings to allow ingress of cold air into said chamber, the
arrangement of the whole being such that the heated air passes up into the
radiating pipes through the perforations in which radiating pipes, said heated air
escapes into the room, while at the same time the supply of air in the chamber is
replenished through the openings at the lower part of said chamber as described.
It is found that if the air in the room or chamber in which my improved
apparatus is being used, be permitted to enter the chamber at the lower openings
referred to, said air becomes unduly warm and dry by reason of its constantly
circulating through the hot air chamber, to obviate which I cause the said lower
openings in the chamber to communicate with say, the air or atmosphere outside
of the building or with any other air supply so that a constant supply and
circulation of altogether fresh air through the heating chamber into the room
takes place.
I wish it to be understood that I do not confine myself to any particular
construction of the different parts constituting my invention nor to any material
of which said parts may be made.
I prefer also to provide the hot air chamber with shelves or partitions of such
a construction and disposition as to compel the air, while circulating and being
heated in said chamber, to travel in a more or less circuitous path therethrough so
that said air will be exposed to a larger heating surface than it would if merely
allowed to pass directly through said chamber into the radiating pipes, the current
of air is also thereby increased.
I prefer also to provide the radiating pipes as well as the lower or supply
openings with suitable taps or cocks, so that the amount of air admitted into the
room or into the chamber or equivalent may be regulated.
I may attach to the ends of the radiating pipes any disinfectant for purifying
the atmosphere, which is sometimes essential, for example in hospitals or for sick
rooms.
In order that my invention may be fully understood I will now refer to the
annexed drawings in which
Figure 1. is a front elevation of my invention.
Figure 2. is a section of my invention through line in Figure 1

page_text: is the grate having the fire bars b. c is a chamber or casing in which the
partitions care arranged as shown. f is the inlet to the chamber or casing e' and
the air passes under the grate from the inlet e thereto. The hot air leaves the
outlet pipe d which is carried to suitable parts of the room and may be perforated
when required. If desired cold air may be allowed to enter the heating chamber
or casing cat or about the aperture or opening f. The fire rests upon the side
or wall g of the chainber or casing c¹ thus heating the air in same.
It will be understood that any convenient form of valve or tap may be employed
to regulate the entrance and exit of air to and from the beating chamber or
casing c¹.
I also sometimes find it convenient to provide the outlets or ends of the radiating
or heating pipes with a suitable disinfectant so that the hot air may become
impregnated with same.
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. The improved construction of stove or grate consisting of a chamber or
casing containing partitions or shelves and which is heated by the fire, said
chamber or casing having inlets and outlets for air, the heated air passing from
the outlets into the room or space to be supplied with same; with or without
regulating valves or taps and disinfecting material substantially as described.
2. The combined construction and arrangement of the various parts substantially
as illustrated & described herein.
