page_text: LETTERS PATENT to Joseph Davis, of Birmingham, in the County of
Warwick, Manufacturer, for the Invention of "A NEW OR IMPROVED
METHOD OF MANUFACTURING THE SMALL COKE, COMMONLY CALLED BREEZES,
WHICH SAID METHOD OF MANUFACTURE ECONOMISES HEAT AND EFFECTS THE
SUPPRESSION OR PARTIAL SUPPRESSION OF SMOKE.".
Scaled the 19th September 1856, and dated the 17th June 1856.
PROVISIONAL SPECIFICATION left by the said Joseph Davis at the Office
of the Commissioners of Patents, with his Petition, on the 17th June
1856.
I, JOSEPH DAVIS, of Birmingham, in the County of Warwick, Manufac-
turer, do hereby declare the nature of the said Invention for "A NEW OR
IMPROVED METHOD OF MANUFACTURING THE SMALL COKE, COMMONLY CALLED BREEZES,
WHICH SAID METHOD OF MANUFACTURE ECONOMISES HEAT AND EFFECTS THE SUP-
PRESSION OR PARTIAL SUPPRESSION OF SMOKE," to be as follows:-
My Invention consists of a coke oven for making the small coke, called
"breezes," constructed and arranged as hercin-after described. The said coke
oven consists of a chamber or furnace provided with doors, by which the coal
to be coked is introduced, and the admission of air regulated.
The said oven is also provided with flues and dampers, by which the heated
air and flame can be conducted therefrom, either into a stack or chimney, or
into the furnace or fire-place of a steam boiler or elsewhere, where it can be
applied to heating or other useful purpose. When the heated air from the

page_text: coke oven is conducted into the furnace of a steam boiler it may be delivered
at or near the bridge of the said furnace, when it will effect the suppression
or partial suppression of smoke from the steam boiler furnace. The heat
from the coke oven also increases the production of steam from the boiler.
The heated air from the coke oven may be applied to other heating purposes.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Davis in the Great Seal Patent Office on the 16th
December 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPII
DAVIS, of Birmingham, in the County of Warwick, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Iler Letters
Patent, bearing date the Seventeenth day of June, in the year of our Lord
One thousand eight hundred and fifty-six, in the nineteenth year of IIer reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Joseph Davis, Her special licence that I, the said Joseph Davis, my execu-
tors, administrators, and assigns, or such others as I, the said Joseph Davis,
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 "A NEW OR IMPROVED METHOD OF
MANUFACTURING THE SMALL COKE, COMMONLY CALLED BREEZES, WHICH SAID METHOD
OF MANUFACTURE ECONOMIZES HEAT AND EFFECTS THE SUPPRESSION OR PARTIAL
SUPPRESSION OF SMOKE," upon the condition, (amongst others) that I, the said
Joseph Davis, 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
Scal Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, tle said Joseph Davis, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
etatement thereof, that is to say:

page_text: My Invention consists of a coke oven, constructed, arranged, and used as
berein-after described, and illustrated in the accompanying Drawing, for the
manufacture of the small coke called breezes, for economizing of heat and
for the suppression or partial suppression of smoke.
:
Figure 1 of the accompanying Drawing represents in elevation, Figure 2
in vertical section, and Figure 3 in plan, a coke oven, combined with the
furnace of a steam boiler, constructed according to my Invention. The said
coke oven consists of a chamber or furnace a, provided with doors b, b, by
which said doors the coal to be coked is introduced and the admission of air
regulated. The draught may be further regulated by means of the damper c.
The oven a is also provided with flues d, in which flues dampers may be
situated. The heated air and flame from the oven a may be conducted there-
from either into a stack or chimney, or into the furnace or fire-place e of a
steam boiler f, or the said heated air and flame may be conducted elsewhere,
where they can be applied to beating or other useful purpose. When the
flame and heated air from the coke oven a are conducted into the furnace e of
a steam boiler f they may be delivered at or near the bridge of the said
furnace, when they will effect the suppression or partial suppression of the
smoke from the said furnace. The heat from the coke oven a also increases
When the coal in the oven a has

the production of steam in the boiler f.
been converted into the small coke called
by the closing of the doors b, b, damper c, and the door g of the ash-pit; and
the breezes are cooled by the introduction of a jet of water unto the said oven,
the said water being directed upon the breezes; or the said breezes may be
withdrawn from the oven in a heated state, and afterwards cooled by water
or otherwise. Although I prefer to place the coke oven on the side of the
boiler, as represented, yet it may be placed under the boiler, or in any other
convenient situation.
Although I have only represented in the accompanying Drawing the com-
bination of a coke oven for manufacturing breezes with a steam boiler, yet
the said oven may be combined with any other furnace for the purpose of
increasing its heat, and suppressing or partially suppressing its smoke; but I
believe the nature of my said Invention will be sufficiently understood by the
description herein given, and illustrated in the accompanying Drawing.
The size and form of the ovens may be varied to suit the quantity of breezes
to be manufactured, and the particular purposes to which the flame and heated
air from the said ovens are to be applied.
Having now described the nature of my said Invention, and the manner of
carrying the same into effect, I wish it to be particularly understood that I do

page_text: not limit myself to the precise details herein described and represented, as the
same may be varied without departing from the nature of my said Invention;
but I claim as my Invention the new or improved method of manufacturing
the small coke, called breezes, economizing heat, and suppressing or partially
suppressing smoke, herein-before described and illustrated in the accompanying
Drawing that is to say, combining the oven, in which the said breezes are
made, with the furnace of a steam boiler or other furnace, so as to economize
the heat produced in making the said breezes, by causing it to increase the
beat, and suppress or partially suppress the smoke of another furnace with
which it is in communication.
In witness whereof, I, the said Joseph Davis, have hereunto set my hand
and seal, this Fifteenth day of December, in the year of our Lord One
thousand eight hundred and fifty-six.
Witness,
GEORGE SHAW.
