COMPLETE SPECIFICATION.
Improvements in or pertaining to Domestic Fire Places.
I, ADOLPH HENRY LOUIS of Crecy, Anerley Road, Norwood, in the County of
Surrey, 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 :-
It has been proposed to provide chambers bebind fire places to warm air to be
admitted into rooms. Now my invention has for its object to enable existing fire
grates to be adapted, without removal, for warming air and diffusing it, either alone
or with disinfectants or substances for the relief of sufferers from bronchitis or other
ailments.
The air may enter the warming chamber cither directly from the
apartment to be warmed or from some external source. Within the grate I provide
a jacket or inner wall (hereinafter called a lining) adapted to enclose a space at the
sides and back within the ordinary fire place so that the fuel containing space is
reduced in size and is surrounded on three sides by an air warming chamber. To
this air is admitted through suitable openings or pipes, either from the room in

provided for discharging the warmed air into the apartment.
Where desired I provide in connection with these outlets contrivances for holding
vessels charged with disinfectant, or fluid to be taken up by the escaping warm air
and distributed into the room or apartment.
The lining to which I have referred is constructed in parts overlapping one
another at the joints and formed with lugs connected together by screw bolts the
arrangement being such that a given lining can be adjusted to suit fireplaces of
different sizes. When such a lining has been fitted into a fire grate the joints
between the ordinary walls of the fire grate and the lining can be made air tight by
means of suitable cement.
In the accompanying drawings,
Fig. 1 is a front view of an ordinary fire place provided with apparatus according
to this invention, the front bars being broken off to show the apparatus more
clearly.
Figs. 2 and 3 are horizontal sections on the line a x and y y respectively of
Fig. 1.
Fig. 4 is a vertical section on the line y₁ y' of Fig. 1.
A is a lining of plate metal formed with an upper flange A' and end flanges A
so that when it is placed within a fire grate as shown it will in conjunction with the
sides and back of the grate, enclose a space A' which forms the air warming
chamber which may be in communication with the ash pit through the space
between the rear ends of the fire bars. The lining which may advantageously be
formed of cast iron is in the arrangement shown in Figs. 1 to 4 inclusive made in
four parts which overlap one another at the back and sides of the grate, one of the
parts of each adjacent pair of parts having a vertical extension B which fits
telescopically behind the other and also a flanged upper portion B' which fits
below the upper flange A¹ on the adjacent part of the lining. Each of the parts
has a lug C and through the lugs of each pair passes a bolt D provided with
nuts D¹ located at each side of each lug the arrangement being such that the parts
forming each side or the back can if necessary be moved closer together or further
apart to fit and become firmly fixed in the grate to which the apparatus is to be
be applied and be then rigidly fixed together and to the grate within which it is
placed. As will be obvious various other means can be adopted for this purpose.
EE are pipes by which additional air is admitted to the air warming chamber A³.
These pipes which may be formed of iron or brass, communicate with the warming
chamber through short tubes or necks on to which they are screwed and which are
cast in the lower end parts of the lining A. F F are pipes which serve as outlets
for conveying the heated air from the air chamber and discharging it into the room
or apartment as indicated. Along the upper edge of the lining a flange or bead G
is provided as shown, so that when the various parts have been fixed in position in
a fire grate, cement, fireclay or other suitable filling can be placed inside the flange
in order to make an air-tight joint with the sides and back of the grate. The
end flanges A may be each formed with a vertical bead for a like purpose. On
the upper end of each of these pipes may be fitted a holder as shown for supporting
a bottle of liquid. These holders cach comprise a perforated plate I having on its
underside a socket I adapted to be readily engaged with the upper end of the
corresponding pipe F and from which rise wires or supports 12 carrying a ring I³
in which rests the vessel J serving as a receptacle for liquid such as perfume,
disinfectant or water. The vessel may be an inverted bottle or flask in the mouth
of which is securely inserted a piece of sponge or other suitable porous or
perforated material, and in the upper part of which is an adjustable air inlet
valve by which the out flow of the perfuine, disinfectant or water can be regulated.
By these means the air issuing from the upper ends of the pipes F, F can be
suitably impregnated with perfume, disinfectant or water vapor. When water is
used, the air inlet valves can be so regulated that water will flow down the pipes
and connected parts and be converted into steam which will issue into the room

page_text: or apartment with the heated air. Thus the arrangement described may, when
necessary, be used in lieu of a bronchitis kettle for providing a moist atmosphere
to an apartment.
Fig. 5 is a similar view to Fig. 2 showing a modification in which each of the
side portions of the lining is made in one piece with one of the adjustable back
portions. In this case the said side portions may be made of any desired length
less than that of the side of the grate, and the lining is fixed in the grate by
means of pipes K that are screwed onto corresponding screw threaded nozzles on
the said side portions and are each provided with a nut L adapted to be screwed
tight up against the inner side of the pair of fire bars between which the outer
end of the pipe passes. The outer ends of the pipes K are provided with sockets
or other suitable fittings by which the pipes E can be readily connected to and
disconnected from the said pipes K.
As will be obvious one outlet pipe F only may be used, but I prefer to use two
as shown.
I have found that with apparatus constructed and applied according to my
invention, rooms can be warned in a more uniform and efficient manner than is
usually the case with fire places of ordinary construction and with a much smaller
consumption of fuel than is usually required with such fire places.
The apparatus can be easily and quickly applied to fire places, adapted for
burning either solid or gaseous fuel, without alteration of such fire places, and
without the aid of skilled labor, the construction moreover being such that the
apparatus can be readily adapted to suit fire places of different sizes.
•
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A lining A constructed in adjustable parts overlapping one another and
provided with air inlet and outlet pipes and with means for connecting the parts
together and fixing them in place, the arrangement being such that the lining can
be readily applied to and fixed within an ordinary domestic fire-grate so as to form
with the rear portion thereof an air space or chamber into and through which air
will flow when a fire is burning in the grate, and so that such air will be discharged
in a warm or heated state into the apartment in which the fire grate is located
substantially as herein before described with reference to the examples illustrated
in Figs. 1 to 4 inclusive and in Fig. 5 of the drawings annexed.
2. Apparatus of the kind referred to in the preceding claim in which the air
outlet pipe or pipes is or are provided with contrivances for holding vessels charged
with disinfectant or other fluid to be taken up by the escaping warm air and
distributed into the apartment in which the fire place is located, substantially as
described.
