PROVISIONAL SPECIFICATION.
Improvements in Means for Heating and Distributing Air in Stoves
and Fireplaces.
I, HENRY MARTYN RYDER, Electro-metallurgist, of 54, Charlotte Road, Edg-
baston, Birmingham, in the County of Warwick, do hereby declare the nature of
this invention to be as follows:-
The idea set forth in the subjoined plans (Figures 1 & 2) is to utilize the heat
which in an ordinary fire place goes up the chimney & is therefore wasted.
FIGURE 1.
(A) is a hollow iron casting or chamber with an inlet at (B) & an outlet at (C).
The bottom of this casting should be on a level with the back of the fire, & slope
forward over it.
(D) is a pipe going to outside air & can be run either under floor, skirtboard or,
where the fire place is on an outside wall, a connection may be got through the
wall at back of fire place.
(C) the outlet has a pipe connected which may be carried up the chimney to
room above at register (F) or to the same room at register (E).
These registers are arranged like a Venetian blind, & may be regulated or shut
off at will.
.
When the fire is burning the heat which usually goes up the chimney, is
absorbed by iron casting: the air inside becomes heated & rises through (C) to
room above, cold air enters at (B) which becomes heated in turn, & a constant
current of warm air is rising through (C) as long as fire is burning.
The advantages of this arrangement are as follows:-
Two rooms can be heated with one fire.
-
No heat, which, in an ordinary fire-place comes into the room, is used, but only
that which usually goes up the chimney.
No air is drawn from the room itself for supply, which would create more
draught, but a constant supply of pure air from outside.
This arrangement can be supplied to any existing fire place at a small cost.
The additional heat is obtained without increased cost of fuel.
In an ordinary fire place fully 50% of the heat generated goes up the chimney.
By this arrangement it is all saved.
During winter months a good fire is often left burning at night which lasts some
hours. A sliding panel might be arranged to cover front of grate when down-
stairs room is done with, in which case the whole of the heat from the fire would
be absorbed by iron casting & carried to upstairs room.

I, HENRY MARTYN RYDER, Electro-metallurgist, of 54, Charlotte Road, Edg-
baston, Birmingham, in the County of Warwick, 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 heating apparatus, and particularly to fireplaces or
grates, and the object thereof is to provide means for utilizing the heat which
usually escapes through the chimney or flue in heating apparatus of this class.
The invention is fully disclosed in the following specification, of which the
accompanying drawing forms a part, in which :-
Fig. 1, is a perspective view of an ordinary grate heating device: and
Fig. 2, a similar view showing a modified form of construction, one of the side
walls of the escape flue or chimney being removed to better show the construction.
In the drawing forming part of this specification, the separate parts of my im-
provement are designated by the same numerals of reference in each of the views,
& in said drawing--reference being made to Fig. 1-I have shown at 5 an ordinary
grate, & at 6, the escape flue or chimney thereof, said parts being shown in per-
spective and I have also shown at 7, an ordinary mantel, & within the fire chamber
or recess of the grate & directly over the same I place, in practice a hollow iron
casting or casing 8, which is preferably rectangular in cross section, the longer
side thereof being directed backwardly & fitted against the back wall 9, of the
fire chamber in which the grate is placed.
The front side & rear side of the said hollow casting come together at the bottom
thereof, & the front side is inclined outwardly & upwardly over the grate 10, & the
top thereof is inclined backwardly & upwardly from the upper end of the front
side as clearly shown in the drawing.
I also provide a pipe 11, which is shown in dotted lines in Fig. 1, & which is
introduced into the wall of the grate receptacle at one side thereof, & carried
upwardly therethrough, & passed into one side of the said hollow casting 8, as
shown in dotted lines at 12, and another pipe 13, communicates with the upper
side of the said hollow casting as shown at 14, & is provided with branch pipes 15
& 16 both of which are shown in dotted lines, & said branch pipes communicate
with air registers 17 & 18, the first of which is placed beneath the mantel 7, & the
second in one side of the chimney or flue near the top of the compartment or
room in which the grate is placed.
The pipe 13, is also carried upwardly as shown at 19, & also communicates with
other air registers placed in other or upper compartments, & the operation of this
form of construction will be readily understood from the foregoing description,
when taken in connection with the accompanying drawing & the following state-
ment thereof.
The air registers 17 & 18 may be of any desired construction, & I have also
shown a cord 20, by which the heat register 18 may be operated.
The pipe 11 by which the air is supplied to the hollow casting 8, or the
chamber therein is supplied with pure air from outside of the chimney, & my

page_text: improved heating apparatus does not interfere with the operation of the grate,
& the casing 8 may be of any desired form or construction, & may be secured in
the grate receptacle in any desired manner, the only object in this connection
being to so form said casing or casting that it will not interfere with the operation
of the grate.
It will be understood that the casting or casing 8 may be made in any desired
manner; & need not necessarily be cast. & in Fig. 2, I have shown a modification
in which the air pipe 11 is carried through the back wall 9, said air pipe being
shown in dotted lines.
It will also be apparent that my improvement may be applied to an ordinary
fireplace, & many changes in, & modifications of the construction herein described
may be made without departing from the spirit of my invention or sacrificing its
advantages.
By means of my invention, the escape heat or heat which is usually lost by
being dissipated up the escape flue or chimney of a fireplace or grate heater, is
utilized to a large extent, & a number of compartments may be heated, all that is
necessary being to provide suitable pipes or conveyers which communicate with
the casting or casing 8, & which convey the air to registers located in said
compartments.
Having now particularly described & ascertained the nature of my said
invention, & in what manner the same is to be performed I declare that what
I claim is:
1
1. The combination, with the receptacle of a fireplace or grate, of a casing which
is placed therein & which is provided with a supply pipe which opens outside of
the compartment in which the fireplace or grate is placed, said casing being also
provided with a distributing pipe or pipes by means of which connection is made
with air registers located in rooms to be heated substantially as shown & described
2. The combination with a grate receptacle of a casing secured therein over the
grate & adjacent to the back wall of said receptacle, an air supply pipe which
communicates with said casing & which opens outwardly, and an air distributing
pipe which communicate with said receptacle, & by means of branch pipes with
air registers located in rooms or compartments to be heated substantially as shown
& described.
