Co., Patent Agents, Southampton Buildings, London, for the Invention of "IM-
PROVEMENTS IN STOVES." A communication from abroad by Messrs. Jewett &
Root, of Buffalo, New York, United States of America.

PROVISIONAL SPECIFICATION left by the said William Robert Lake at the
Office of the Commissioners of Patents on the 14th October 1876.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. IMPROVEMENTS IN STOVES." A communication.
<
This Invention relates to a stove designed for burning soft or bituminous coal, and
in which the fuel magazine is surrounded by a draught passage having openings
near the bottom of the inagazine, so that a downward and inward draught is caused
to strike the burning coal at the bottom of the magazine in addition to the ordinary
upward draught through the grate, thereby supplying the requisite quantity of air
to the burning fuel in such manner as to ensure the complete combustion thereof.
The fuel magazine is suspended by means of a flange resting upon an offset or
flange on the top of the stove. A draught passage surrounds the magazine and the
outer casing. A cast ring is provided on its inner side with recesses or notches
forming air escape openings communicating with the draught passage, and opening
inwardly below the said magazine. The said ring is preferably suspended by means
of a flange resting upon the lower flange of a secondary ring or short cylinder sup-
The said magazine rests
ported upon a flange formed on the inner side of the case.
with its lower edge upon the said ring, and is retained in place thereon by upwardly
projecting lugs.
An upward air passage is arranged within the downward draught passage at the
front of the stove to communicate with the draught passage at the top. The said
upward passage opens through the front wall of the stove, and is provided with a
damper or register for regulating the admission of air.
Openings are formed in the upper portion of the magazine below the cover thereof
for admitting the gases which may be liberated by the heating of the coal in the
magazine to the air passage, in which they commingle with the air, and are carried
downward by the draught into the fire, where they are consumed.

page_text: The aforesaid ring being supported in the stove, as above described, can be readily
removed when burned out, and replaced by a new one.
The air admitted by the register ascends through one passage, and then descends
through the other passage, and strikes the burning fuel at the base of the magazine
in an inward and downward direction, thoroughly permeating the same, and pro-
ducing in conjunction with the ordinary upward draught through the grate a most
complete combustion of the fuel, thereby enabling soft or bituminous coal to be
burned without generating noxious gases or smoke.
The damper permits the supply of air to be so regulated that the fire can be
readily kept burning all night.
The magazine being suspended by means of the flange, can be jarred from time to
time to prevent the coal from adhering to the sides thereof.

DESCRIPTION OF THE DRAWING.
Figure 1 is a vertical section of a stove provided with the said improvements;
Figure 2 is a horizontal section on the line x, x, Figure 1. Like letters indicate the
same parts in both of these Figures.
A is the outer shell or case of the stove; B, the fire-pot; C, the grate; and D,
the smoke pipe thereof.
E is the fuel magazine suspended by means of a flange e resting upon an offset or
flange on the top of the stove. F is a draught passage surrounding the magazine E,
and formed by the latter and the outer casing A. G is a cast metal ring provided
on its inner side with recesses or notches g, forming air escape openings communi-
cating with the draught passage F, and opening inwardly below the magazine, as
clearly shown in Figure 1. The ring G is preferably suspended by means of a
flange resting upon the lower flange h of a secondary ring or short cylinder H, sup-
ported upon a flange i formed on the inner side of the case A. The magazine E
rests with its lower edge upon the ring G, and is retained in place thereon by
upwardly projecting lugs k.
L is an upward air passage arranged within the downward draught passage F at
the front of the stove so as to communicate with the draught passage Fat the top.
The upward passage L opens through the front wall of the stove, and is provided
with a damper or register 6 for regulating the admission of air.
m represents openings formed in the upper portion of the magazine E below the
cover thereof for admitting the gases which may be liberated by the heating of
the coal in the magazine to the air passage F, in which they commingle with the
air, and are carried downward by the draught into the fire, where they are
consumed.
Figure 1 is a vertical section of a stove provided with the said improvements;
Figure 2 is a horizontal section on the line x, x, Figure 1. Like letters indicate the
same parts in both of these Figures.
A is the outer shell or case of the stove; B, the fire-pot; C, the grate; and D,
the smoke pipe thereof.
E is the fuel magazine suspended by means of a flange e resting upon an offset or
flange on the top of the stove.' F is a draught passage surrounding the magazine E,
and formed by the latter and the outer casing A. G is a cast metal ring provided
on its inner side with recesses or notches g, forming air escape openings communi-
cating with the draught passage F, and opening inwardly below the magazine, as
clearly shown in Figure 1. The ring G is preferably suspended by means of a
flange resting upon the lower flange h of a secondary ring or short cylinder H, sup-
ported upon a flange i formed on the inner side of the case A. The magazine E
rests with its lower edge upon the ring G, and is retained in place thereon by
upwardly projecting lugs k.
L is an upward air passage arranged within the downward draught passage F at
the front of the stove so as to communicate with the draught passage Fat the top.
The upward passage L opens through the front wall of the stove, and is provided
with a damper or register / for regulating the admission of air.
m represents openings formed in the upper portion of the magazine E below the
cover thereof for admitting the gases which may be liberated by the heating of
the coal in the magazine to the air passage F, in which they commingle with the
air, and are carried downward by the draught into the fire, where they are
consumed.

page_text: The ring G being supported in the stove, as above described, may be readily
removed when burned out, and replaced by a new ring.
The air admitted by the register ascends through the passage L, and then
descends through the passage F and strikes the burning fuel at the base of the
magazine E in an inward and downward direction, thoroughly permeating the same,
and producing in conjunction with the ordinary upward draught through the grate
a most complete combustion of the fuel, thereby enabling soft or bituminous coal to
be burned without generating noxious gases or smoke.
The damper permits the supply of air to be so regulated that the fire can be
readily kept burning all night.
The said magazine being suspended by means of the flange e, can be jarred or
shaken from time to time to prevent the adhesion of coal to the sides thereof.
Having thus fully described the said Invention as communicated to me by my
foreign correspondents, and the manner of performing the same, I wish it understood
that I claim,
First. The combination with the fuel magazine of the air passage provided with
openings near the bottom of the said magazine to produce a draught in a downward
and inward direction through the burning fuel, as herein-before set forth.
Second. The gas escape openings arranged in the magazine to communicate with
the descending air flue, so that the gases generated in the magazine are conducted
into the fire, as herein-before set forth.
Third. The magazine suspended at the top by the flange in combination with the
ring provided with lugs, as above described and for the purpose set forth.
Fourth. The combination with the fuel magazine of the surrounding downward
air passage, the cylinder, and the ring provided with recesses, as herein-before set
forth.
Fifth. The combination with the fuel magazine of the surrounding air passage
provided with openings and the ascending air passage provided with a damper, as
herein-before set forth.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Thirteenth day of April, in the year of our Lord One
thousand eight hundred and seventy-seven.
