PROVISIONAL SPECIFICATION.
Improvements in and relating to the Drying of Fish and other
Substances.
I, HENRY SMETHURST, of Fish Docks, Grimsby, in the County of Lincoln, Fish
Salesman, do hereby declare the nature of this invention to be as follows:-
This invention relates to the artificial drying of fish and other substances
whereby the exposure of the fish to the open air or sun is obviated, and whereby
the drying operation can be effected independently of the weather.
The invention consists of a drying shed or kiln around or through which flnes
are provided in communication with a fire from which the products of combustion
pass through to a chimney, while hot air chambers or flues are arranged imme-
diately above the flues through which the products of combustion pass, so that
the air within such hot air chambers or flues is heated, thereby heating the air
within the kiln or shed. The air within the drying shed or kiln is carried away
preferably from the upper part thereof by such means as a fan or chimney.
The invention further consists in the arrangement of kilns or sheds side by
side with a fire so arranged in an intermediate position that the products of com-
bustion therefrom may pass equally through the respective flues of the drying
sheds or kilns or through one only so that the respective kilns may be cut off
from the supply of heat for the purpose of withdrawing or introducing the fish
or other substances to be dried.
The invention also consists in the specific design of drying sheds or kilns as
hereafter described.
In carrying the invention into effect according to a preferred construction I
build the drying sheds or kilns in duplicate of brick, so that one of the drying
sheds or kilns may be in use while the fish from the other are being withdrawn.
or while the other is being cleaned, and upon the floor and around the sides of
each of such drying sheds or kilns, flues are provided in communication at one
end with a fire placed in an intermediate position between the respective drying
sheds or kilns, and at the other with a central chimney or chimneys. Imme-
diately above such smoke flues, air chambers or flues are provided around each
side of the building. The heated gases from the fire travel through the smoke
flues that are arranged around the building and pass un through the chimney and
in their passage they communicate their heat to the air in the air flues or
chambers provided above them so that thereby the air within the respective kilns
or sheds in which the fish or other substance is stored is heated and dried, and in
heating rises to the top of the respective chambers whence it is taken through a
lateral flue by means of a fan or by means of the draught of a chimney so that
thereby there may be continual circulation of air within the chambers. The
hot air withdrawn from the top of these chambers may be caused to pass within
the air chambers or flues whence they may find egress therefrom into the
chambers again. The air may, however, not be circulated within the air
chambers or flues but air bricks may be provided at intervals for the purpose of

page_text: ventilation from the exterior or interior, the orifices being capable of being closed
or opened as required.
On each side of the grate or fireplace rooms may be provided for use respec-
tively, for instance, as an engine room and for storage of fuel. In the engine
room the fan employed may be mounted and driven by a motor. Between the
two rooms a recess may be provided so as to afford ample space for attending
to the fire. The doors admitting to these respective chambers may preferably
open out into this intermediate space.
It will be understood that by this means fish or any other material may be
stored within the sheds or kilns and may be effectively dried and heated by
means of hot air the temperature of which may be regulated as desired.

Improvements in and relating to the Drying of Fish and other
Substances.
I, HENRY SMETHURST, of Fish. Docks, Grimsby, in the County of Lincoln, Fish
Salesman 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:-
This invention relates to the artificial drying of fish and other substances
whereby the exposure of the fish to the open air or sun is obviated, and whereby
the drying operation can be effected independently of the weather.
The invention consists of a drying shed or kiln around or through which flues
are provided in communication with a fire from which the products.of combustion
pass through to a chimney, while hot air chambers.or flues are arranged imme-
diately above the flues through which the products of combustion pass, so that
the air within such hot air chambers or flues
within the kiln or shed. The air within the drying shed, or kiln. is carried away
heated, thereby heating the air
preferably. from the upper part thereof by such means as a fan or chimney.
The invention further consists in the arrangement of kilns or sheds side by
side with a fire so arranged in an intermediate position that the products of com-
bustion therefrom may pass equally through the respective flues of the drying
sheds or kilns or through one only so that the respective kilns, may be cut off
from the supply of heat for the purpose of withdrawing or introducing the fish
or other substances to be dried.
The invention also consists in the specific design of drying sheds or kilns as
hereafter described....
In the accompanying sheet of explanatory drawings
'
Figure 1 is a sectional plan of one form of my improved drying kiln or
shed, and.
Figure 2 is a transverse section taken on the line a, y. through the, building
and the engine room.
',
In carrying the invention into effect according to a preferred construction I
build the drying sheds or kilns A, A' in duplicate of brick, so that one of the
drying sheds or kilns A may be in use while the fish from the other A' are being

page_text: withdrawn, or while the other is being cleaned, and upon the floor and around
the sides of each of such drying sheds or kilns, flues B are provided in communi-
cation at one end with a fire C placed in an intermediate position between the
respective drying sheds or kilns, and at the other with a central chimney or
chimneys D. Immediately above such smoke flues B air chambers or flues E are
provided around each side of the building. The heated gases from the fire Û
travel through the smoke flues B that are arranged around the building and
pass up through the chimney and in their passage they communicate their heat
to the air in the air flues or chambers E provided above them so that thereby
the air within the respective kilns or sheds in which the fish or other substance
is stored is heated and dried, and in heating rises to the top of the respective
chambers whence it is taken through a lateral flue F by means of a fan G or
by means of the draught of a chimney so that thereby there may be continual
circulation of air within the chambers. The hot air withdrawn from the top of
these chambers may be caused to pass within the air chambers
flues whence they may find egress therefrom into the chambers again.
The air may, however, not be circulated within the air chambers or flues
but air bricks or grids H may be provided at intervals for the purpose of ventila-
tion from the exterior or interior, the orifices being capable of being closed or
opened as required.
or
On each side of the grate or fireplace rooms K, L, may be provided for use
respectively, for instance, as an engine room and for storage of fuel. In the
engine room the fan G employed may be mounted and driven by any ordinary
engine or motor. Between the two rooms a recess M may be provided so as to afford
ample space for attending to the fire. The doors admitting to these respective
chambers may preferably open out into this intermediate space.
It will be understood that by this means fish or any other material may be
stored within the sheds or kilus and may be effectively dried and heated by
means of hot air the temperature of which may be regulated as desired.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. The improved method of drying fish and other substances in which a build-
ing is employed as a storage chamber around which the flue from a furnace
passes to heat an adjacent air flue or conduit through which the air passes to
the drying chamber area and from which it is then extracted by means of the
draught induced by a chimney, fan or exhauster, substantially as and for the
purposes hereinbefore described and as illustrated in the accompanying drawings.
2. The improved duplex drying chambers for drying fish or other substances
by means of hot air heated by contact with the flues containing the gases and
products of combustion which travel from the furnace or grate round the build-
ing before passing to the chimney or exhauster such chambers being capable of
use together or independently, substantially as and for the purposes herein before
described and as illustrated in the accompanying drawings.
