Year: 1862

page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet Street,
in the City of London, Patent Agent, for the Invention of "IMPROVEMENTS
IN STOVES OR APPARATUS FOR HEATING AND DRYING."-A communication
from abroad by Etienne Sauret, of Remiremont, and Eugene de Fleury,
of Rolanges, both in the Empire of France.
Sealed the 19th June 1863, and dated the 22nd December 1862.
PROVISIONAL SPECIFICATION left by the said Richard Archibald Brooman
at the Office of the Commissioners of Patents, with his Petition, on the
22nd December 1862.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN STOVES OR APPARATUS FOR HEATING AND DRYING," to be as
follows:-
This Invention consists in the construction of apparatus for heating, and
drying, in which the air is heated by being caused to circulate in a zig-zag
direction through a casing surrounding pipes and chambers, in which the
products of combustion from a stove are made to pass, all as hereafter
described. The stove consists of a grate with a dome-shaped casing above
it in communication with a series of chambers, one above the other, and con-
nected by pipes; each chamber containing plates for dividing the products of
combustion in their passage to the outlet or chimney. The apparatus, just

page_text: described, is enclosed in a casing with division plates alternately fixed to each
chamber. Air is admitted near the bottom of the apparatus, and circulating
round and in contact with the chambers is heated and passes upwards in
a zig-zag direction to be used for heating or drying as required.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Archibald Brooman in the Great Seal Patent Office
on the 22nd June 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of December, in the year of our
Lord One thousand eight hundred, and sixty-two, in the twenty-sixth year of
Her reign, did, for Herself, Her, heirs and successors, give, and grant unto
me, the said Richard, Archibald Brooman, Her, special licence that I, the
said Richard Archibald Brooman, my executors, administrators, and assigns,
or such others as I, the said Richard Archibald Brooman, my executors,
administrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might. make, use, exercise, and vend, within
the United Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "IMPROVEMENTS IN STOVES OR APPARATUS FOR
HEATING AND DRYING," (communicated to me from abroad by Etienne Sauret,
of Remiremont, and Eugene de Fleury, of Rolanges, both in the Empire
of France,) upon the condition (amongst others) that I, the said Richard
Archibald Brooman, my executors or administrators, by, an instrument in
writing under my, or their, or one of their hands and seals, should, particularly.
describe and ascertain the nature of the said Invention; and in what manner,
the same was to be performed, and cause the same to be filed; in the Great
Seal Patent Office, within six calendar months next and immediately, after the
date of the said Letters Patent.

NOW KNOW YE, that, I, the said Richard Archibald, Brooman, do hereby.
declare the nature of the said Invention, and in what manner, the same, is
to be performed, to be particularly described and ascertained in and, by, the,
following statement, thereof, reference, being, had, to the Drawings, hereunto,
annexed, that is to say :-

page_text: This Invention consists in the construction of apparatus for heating and
drying, in which the air is heated by being caused to circulate in a zig-zag
direction through a casing surrounding pipes and chambers in which the
products of combustion from a stove are made to pass, all as hereafter
described. The stove consists of a grate with a dome-shaped casing above it
in communication with a. series of chambers, one above the other, and, con-
nected by pipes, each chamber containing plates for dividing the products of
combustion in their passage to the outlet or chimney. The apparatus just
described is enclosed in a casing with division plates alternately fixed to each
chamber. Air is admitted near the bottom of the apparatus, and circulating
round and in contact with the chambers is heated, and passes upwards in a
zig-zag direction, to be used for heating or drying, as required.
Figure 1, of the accompanying Drawings, is a front elevation, and Figure. 2
a cross section of a stove constructed according to, this Invention.
a is the outer casing of the stove; b, b,,, 63, are, horizontal division plates,
fixed alternately to the front and back of the casing a,, and causing, the air to
circulate in a zig-zag direction through the spaces c, c, as indicated by the blue
arrows in the Drawing. A is the fire-place surrounded by a dome-shaped
casing.d, in. the. bottom. of which. the.grate. is. fitted, and, which, is, in communi-.
cation at top with the first chamber 9. Air for keeping up combustion
enters the, fire place. through the grating, and by openings e; e; formed all round
the fire-place between it and the casing d'; these openings e communicate with
the lower part of the stove; 9, 9³, 9², are chambers placed above the division
plates 6, 6, 6. The two upper chambers 91, 9, are fitted with double par-
titions or compartments m, m³, so as to form a passage for air through them.
The chambers g, g¹, g³, are connected by pipes h, h³, and an exit pipe or
chimney is connected to the top of the uppermost chamber g; k is a circular
case fitted in the centre of the chamber g, and pierced with holes round its
periphery to allow of the passage of air, which is admitted through the tube j,
and forms a blast. Cold air from the outside of the stove enters the case k,
becomes heated to a high degree, and escapes therefrom through the holes
after having consumed the gases which arise from the casing d, and after
having produced an intense heat at that point. Instead of cold air, steam, or air
mixed with steam may be admitted through the tube j. The products of com-
bustion coming from the casing d diverge round the case k, pass through the
pipe h into the chamber 9', pass round the compartment m, m³, therein, thence
through the pipe h¹ into the chamber g³, round the compartment m, m³, in
that chamber, and finally pass off by the exit pipe i, following in their course
the direction indicated by the red arrows in Figure 2. The air to be heated

page_text: ;
enters through the outer casing a by the opening n, and circulates in a zig-zag
direction round the chambers 9, 9, 9, and through the compartments m, m²
it thus acquires a high temperature, and can be employed for drying and
beating purposes. 0, 0, are openings in the outer casing a, through which
tools may be inserted for cleaning the chambers. These openings may be
formed at the top and bottom of each chamber, or at each side, or as shown in
Figure 1 at top and bottom, as well as at each side. They are closed by
stoppers p to prevent escape of the heated air through them. The number of
chambers 9, 9, 9³, may be varied.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim, constructing
stoves or apparatus for heating and drying, substantially as herein-before
described and illustrated in the accompanying Drawings.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Twenty-second day of June, One 1
thousand eight hundred and sixty-three.
