PROVISIONAL SPECIFICATION.
Improvement in Fuel Economisers for Use in Domestic Fire-grates.
ALBERT JOSEPH STOKES, 21, Burnbank Gardens, Glasgow, Commercial
Traveller, and EDWARD GEORGE PEYTON, 4, Castle Gardens, Gourock, Journalist,
do hereby declare the nature of this invention to be as follows;-
-
The apparatus consists in a chamber formed of cast iron, fire brick or any
other suitable substance, which is placed in a fire grate, the term grate being
applicable to a room fire place, a kitchener or stove. The chamber is open at
the bottom or base, so as to admit air to pass freely in. The front of the cham-
ber is so arranged that it slopes downwards towards the base, surface floor or
fire bar level of the grate. The chamber may face the front or side.
At con-
venient distances louvres or openings are arranged so that the heated air in the
chamber passes into the coal, and thereby causes complete or improved com-
-bustion. The sides and back of the chamber are so constructed, that due allow-
ance is made for expansion and contraction. A feature of the improvement is
the fact that the chamber can be removed at will, for the purpose of being
cleaned. The louvres may be mechanically moved. In the place of the louvres,
the openings for the transmission of air may be tubular or square holes, hori-
zontal or perpendicular bars.

Improvement in Fuel Economisers for Use in Domestic Fire-grates.
We, ALBERT JOSEPH STOKES, of 21, Burnbank Gardens, Glasgow, Commercial
Traveller, and EDWARD GEORGE PEYTON, of 4, Castle Gardens, Gourock,
Journalist, 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:-
-
Our invention relates to improvements in fuel economisers.
In order that our invention may be properly understood and readily carried
into effect we have hereunto appended one sheet of drawings, of which,
Figure 1 is a front elevation of our improvements.
Figure 2 is an end view.
Figure 3 is a sectional end view.

Figure 6 is a similar view of a further modified form of economiser.
Figure 7 is a sectional view of a still further modified form of economiser
which may be built into grate or removably fitted into it.
Figure 8 is a part section and part elevation of a range shewing the economiser
fitted transversely into its side.
Figure 9 is a perspective view of a lattice plate or gridiron for supporting
fire brick corresponding to Figure 7.
Figure 10 is a side elevation of such fire brick, all hereafter more fully
referred to.
The apparatus consists in a chamber A of cast iron, firebrick, or any other
suitable substance, which is placed in a firegrate B, the term grate being applic-
able to a room fire place, a kitchen or stove. The chamber A is open at the
bottom or base so as to admit air to pass freely in, as shewn more particularly
in Figures 3 and 4. The front of the chamber A is so arranged that it slopes
downwards towards the base, surface, floor, or firebar level of the grate. The
chamber A may face the front or side. At convenient distances, louvres or
openings C are arranged so that the heated air in the chamber passes into the
coal D and thereby causes complete or improved combustion as seen more
particularly in Figure 4. The sides and back of the chamber are so constructed
that due allowance is made for expansion and contraction. The openings for
the transmission of air may be tubular or square holes, horizontal or perpendicular
bars, and may be so arranged that a greater or less supply of the heated air in
the chamber may be allowed to pass into the fire place among the coal.
It will be obvious that this chamber can be readily removed at will for the
purpose of being cleaned, which is of course a special advantage.
In the modification illustrated in Figure 5 the economiser is more or less
rectangular in shape, whilst the economiser in Figure 6 is triangular or wedge
shaped in the direction of its length as seen in plan.
In Figure 7 the economiser is shewn with a movable firebrick E as constituting
the top or canopy of the chamber. The said firebrick is supported on a perforated
or latticed plate, shewn more particularly in the detached view Figure 9.
In Figure 8 the economiser is placed underneath the smaller hob in the fire
place, that is to say, the direction of its length is from the front to the back
of the range.
The economiser may be furnished with a door F and a slide G wherewith to
regulate the draught and permit of cleaning. It also may be surmounted with
a firebrick E as shewn.
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. The general arrangement and construction of fuel economisers, substan-
tially, as and for the purposes hereinbefore described and illustrated in the
several figures of the accompanying sheet of drawings.
2. The lattice plate or gridiron for supporting the fire brick, substantially as
described and shewn on the accompanying sheet of drawings.
