Improvements in or applicable to Domestic Fire-grates and Stoves.
We, GEORGE QUICK, of 11, Trebovir Road, and CECIL SANDYS WALKER, of
14, Edwardes Square, both in the County of London, Engineers, do hereby declare
the nature of this invention to be as follows:-
This invention relates to a novel construction of apparatus applicable to domestic
fire-grates and stoves, and by the use of which the combustion of the fuel is
rendered more complete than heretofore, thereby economising the consumption of
fuel and diminishing the production of smoke as a very large portion of the air fed
to the fuel is caused to pass through a preliminary heating chamber from which
it escapes into the fuel at the bottom thereof so that the heated air is forced to pass
up through the whole thickness of the layer of fuel before passing to the chimney.
In carrying out our invention we employ a kind of box which may be of cast
iron, wrought iron, steel or other suitable material and which is open at the bottom,
closed at the top and adapted to be placed in the grate or stove; the said box is
provided with a curved or flat diaphragm or partition dividing it into two passages,
which are in communication with one another at the upper part of the box so that
air, which is drawn in by the chimney draught enters at the lower open end of
the box, passes up and thence downwards and is heated by the box which is in
contact with the fuel. The lower end of the down-take passage in the box is open
so that the heated air passes from the said passage into the lowermost portion of
the layer of fuel through which it passes thereby effecting the complete combus-
tion of the fuel, before escaping into the chimney.
A grate or stove may be provided with one of our fuel economisers at each side
and at the back or with only one at either side or at the back. The apparatus
simply stands upon the bottom grating or fire brick floor of the grate or stove, or
in the case of new stoves it will be obvious that it can be made in one therewith.
When furnished with our apparatus grates or stoves can burn all kinds of coal,
coke, slack, cinders or wood with great economy and without trouble or incon-
venience.

Figure 4 is a sectional plan view illustrating the application of our apparatus
to a domestic fire-grate;
Figures 5 and 6 are views similar to Figure 3 of slightly modified constructions
of the apparatus; and
Figure 7 is a plan view shewing the whole set of apparatus cast or made in one
piece.
a is the box of cast iron, wrought iron or other suitable material, the said box
being open at the bottom as shewn and is the diaphragm or partition which
divides the said box a into two passages which are in communication with one
another. The box is open at its lower part as shewn at e and is provided with
an outlet at the lower part of the upper division so that air, which is drawn in
by the chimney draught, enters at the lower open end of the box, is directed up-
wards by the partition so as to be heated by the box which is in contact with the
fuel, after which it passes downwards and through the outlet into the lower
portion of the fuel in the grate through which it passes, thus effecting the complete
combustion of the fuel before escaping into the chimney.
We may provide a fire-grate with one of our economisers at the back or at either
side of the grate or at the back and one side or at the back and both sides. As
above mentioned and as shewn in Figure 4, the apparatus simply stands upon the
bottom or fire-brick floor of the grate, although, and especially in the case of new
stoves, it can be made in one with the said bottom.
In the arrangement shewn in Figure 5 it will be noticed that the bottom portion
or division of the box a is made broader than the upper part so that the apparatus
covers a larger area of the grate thereby excluding more cold air and admitting
larger quantity of hot air to the fuel.

page_text: In Figure 6 we have shewn a modification which can advantageously be employed
in cases where small coal or breeze is employed as fuel.
Figure 7 illustrates the economiser cast in one piece to form both back and sides
to the grate; this form is adapted to be used in the construction of new grates or
stoves and it may be employed as the sole casing for the fire; or we may arrange
it inside an ordinary fire-brick back and side casings.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. Apparatus applicable to domestic fire-grates and stoves and comprising a
box of cast iron or other suitable material open at the bottom, closed at the top and
provided with a diaphragm or partition so arranged that air, which is drawn into
the box by the chimney draught is directed upwards by the said partition so as to
be heated by the fuel in contact with the box, the said air then being drawn into
the lower portion of the fuel through a suitable orifice in the box, substantially as,
and for the purpose, hereinbefore described.
2. The manufacture and use of apparatus applicable to domestic fire-grates and
stoves, constructed and arranged substantially as hereinbefore described and illus-
trated in the accompanying drawing.
