PROVISIONAL SPECIFICATION.
Improvements in Furnaces applicable to Metallurgical, Chemical,
and other Purposes.
I, JOHN WILKINSON, of Crimbles, Pudsey, in the County of York, Engineer,
do hereby declare the nature of this invention to be as follows:-
The invention relates to furnaces and their application to metallurgical, chemical
and other purposes whereby a steady and maintained heat may be sustained
throughout the length and breadth of the ovens or kilos to be heated. The
furnace is by preference placed underneath or behind the oven or kiln, or may be,
if found more convenient placed at either side or in front.
In carrying out the invention, the oven or kiln may be surrounded on all or a
portion of its sides by a flue or flues through which the heat from the fire passes on
its way to exit main-flue to chimney, at the upper part of the furnace and beneath,
or on the side of the ovens or kilos, I put a solid arch or blocking course of
quarries continuous from front wall to within about twelve inches or eighteen
inches of back wall, according to extent of surface to be heated, and thereby
guiding the heated furnace gases in that direction. These heated gases then pass
under the sole of the upper oven, or in the case of two divide and pass under each
in such volume as may be found most desirable for the purpose desired, and is
confined closely to the exposed surfaces of the ovens or kilns before mentioned';
from the back outlet mentioned the gases pass along to the front and then between
two blocking walls again to the back of the ovens, and between the upper and
lower ones respectively, and so on until the heat is practically spent, when
an exit flue connected with the chimney-shaft.
enters
The furnace, flues, ovens, &c., are preferably constructed of or lined with
firebrick or fire-tiles according as the ovens or kilns are to be worked at a high or
low temperature, and the outer casing or shell not immediately contagious to the
fire may be constructed of ordinary red brickwork. Between the outer casing and
the firebrick linings, a cavity or space may be provided which is filled with silicate
cotton, slag wool, or similar material thus preventing the escape or radiation of any
heat, the material named being incombustible does not burn away.
Some of the advantages of this invention are as follows:-
1. By reason of the proper distribution of heat great economy of fuel is effected,
and inferior kinds of fuel used, whereas usually only the best kinds are found
efficient for the purpose.
2. Uniformity of temperature over the whole surface of the ovens or kilns
thereby conducing to greater effectiveness in distillation.
3. The heat being conveyed around the ovens or kilns as to effect complete
combustion of the furnace gases.
4. No special kinds of fireclay material are necessary, ordinary stock sizes and
shapes being sufficient for the purpose required.
5. The wear and tear of the ovens or kilns usually very heavy with ordinary
firing is reduced to a minimum through complete combustion being obtained.
It will be understood that the foregoing is given by way of illustration, and that
the shapes, materials and proportions of the parts, may be varied in many ways
within the scope of my invention.

1, JOHN WILKINSON, of Crimbles, Pudsey, in the County of York, Engineer,.
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:
The invention relates to furnaces and their application to metallurgical, chemical
and other purposes whereby a steady and maintained heat may be sustained
throughout the length and breadth of the ovens or kilns to be heated. The furnace
is by preferénce placed underneath or behind the oven or kiln, or may be, if found
more convenient placed at either side or in front.
And in order that my invention may be thoroughly understood, I now proceed to
describe the 'accompanying drawing thereof, reference being had to letters and
figures marked' thereon.
"
Fig. 1, is a transverse section on line A. B, of: Fig. 2.
Fig. 2, is a'longitudinal section on line C. D, of Fig. 1.
In carrying out the 'invention, the oven or kiln may be surrounded on all or a
portion of its sides by a flue or flues à through which the heat from 'the fire passes
on its way to an exit' main flue to chimney at the upper part of the furnace and
beneath, or on the side of the ovens or kilns. I put a solid arch.or blocking course
of quarries b'continuous from front wall c to within about twelve inches or eighteen
inches of back wall d áccording to extent of surface to be' beated and 'thereby
guiding the heated furnace gases in that direction. These heated gases then pass
under the sole of the upper ovens a¹¹ and pass inder each flue at in such volume
as may be found most desirable for the purpose desired and then along sides a
heating the exposed surfaces of the ovens a' or kilns before mentioned, and then
drop into the flues' h and along sides of bottom oven all and then under the bottom
along a as indicated by arrows in Fig. 2, until the heat is practically spent when
it enters an exit flue g connected with a chimney-shaft.
The furnace

Alues
ovens a', and other like parts, are preferably constructed
of, or lined with firebrick or fire-tiles according as the ovens or kilns are to be
worked at a high or low temperature and the outer casing or shell f of ordinary red
brickwork. Between the outer casing and the firebrick linings, a cavity or space
may be provided which is filled with silicate cotton, slag wool, or similar material
thus preventing the escape or radiation of any heat, the material named' being
incombustible does not burn away.
Some of the advantages of this invention are as follows
By reason of the proper distribution of heat great economy of fuel is effected
and inferior kinds of fuel used, whereas usually only the best kinds are 'found
efficient for the purpose.
Uniformity of temperature over the whole surface of the ovens 'or kilns thereby
conducing 'to greater effectiveness in .istillation.
The heat being conveyed around the ovens or kilns as to effect complete
combustion, of the furnace guses.

No special kinds of fireclay material are necessary, ordinary 'stock sizes and
shapes being sufficient for the purpose required.
The wear and tear of the ovens or kilns usually very heavy with ordinary firing
is reduced to a minimum through complete combustion being obtained.
It will be understood that the foregoing is given by way of illustration, and that
the shapes materials and proportions of the parts may be varied in many ways
within the scope of my invention.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what [
claim is :-
--
1. In furnaces, the combination of the oven or kiln surrounded on all or a portion
of its sides by flues, and the flues through which the heat from the fire passes on
its way to chimney, and the solid arch or block course of quarries continuous from
front wall to back wall, with the furnace and shell, substantially as herein described
and according to the accompanying drawing.
2. In furnaces, the combination of the furnace, flues, ovens and other like parts,
constructed of firebrick or fire-tiles according as the ovens or kilns are to be worked
at a high or low temperature, with the outer casing or shell, substantially as
herein described and according to the accompanying drawing.
