other Analogous Vegetable Products.
I, JAMES MILNE of the firm of Milne Brothers of the Town and County of
Aberdeen, North Britain, Grain and Produce Merchant do hereby declare the
nature of the said invention for IMPROVEMENTS IN APPARATUS FOR DRYING MALT,
GRAIN, SEEDS AND OTHER ANALOGOUS VEGETABLE PRODUCTS to be as follows:-
Each
This Invention, which relates to improvements in apparatus for drying malt,
grain, seeds and other analogous vegetable products, consists of one or more
screens of wire cloth or gauze or otherwise perforated metal arranged vertically
within a kiln heated below from a furnace, the ascending currents of heated air
drawn upwards by a chimney, exhaust fan or their equivalents being caused to
pass and repass amongst the descending vegetable products under treatment.
of these screens (of which, for brevity, only one is hereinafter described) is com-
posed of two sheets of such perforated material and the said screen is divided in
the direction of its width into two, three or more parts by vertical division plates.
The perforated sides or sheets of the said screen may be arranged throughout their
entire vertical length parallel or obliquely, that is to say, nearer together at their
upper than at their lower extremities; or the said perforated sides may be arranged
parallel or obliquely for a portion of their length, the remaining portion of the
length being formed by the sides of the screen taking a zigzag course.
This said
zigzag part may be either above or below the parallel or tapered portion of the
screen or the said zigzag portion may extend the entire height of the kiln; under
any of these forms which it is caused to take, it is arranged in accordance with
the requirements of the produce which is to be dried within the apparatus. The
screen when used in the zigzag form, is provided at its angles with projecting
fingers arranged to break the descent and thereby mix it, and ensure the uniform
drying of the said malt, grain or other vegetable product under treatment. At the
upper extremity of the screen hoppers and shoots are so arranged as to distribute
the grain equally throughout the width of the screen, and at the lower extremity
of the said screen an arrangement of mechanism is provided to automatically
discharge the dried malt, grain or other vegetable product into the required bins
or other receptacles.
The mechanism employed for this purpose may consist of a roller having one or
more longitudinal grooves such as that described in my Complete Specification

page_text: Number 766 A.D. 1884, or of any other suitable apparatus, but the arrangement
of mechanism which I prefer to employ for this purpose consists of two outlets
formed of sheet iron or its equivalent and mounted upon a horizontal shaft situated
beneath the lower extremity of the perforated screen. The two outlets are
arranged upon this shaft in such manner that only one at a time can be presented
to the opening formed by the lower end of the screen, while between the two said
outlets a plate is arranged to check the descent of the grain during the time
occupied by the moving away of one, and presentation of the other outlet to the
lower or outlet end of the screen. The horizontal shaft is provided with a
quadrant, wheel or its equivalent, having one, two or more notches in its edge.
These notches engage with a projection formed upon a pivoted lever the amount
of resistance offered by which, may be adjusted by a spring. A sand glass, a sand
box or its equivalent is arranged upon a horizontal shaft situated above, below or
near the herein first mentioned shaft and is tilted over by the action of the
oscillating outlets. This sand glass or its equivalent operates in conjunction with
the before mentioned pivoted lever so as to release the shaft carrying the outlets
at any pre-arranged intervals. For this purpose a valve may be arranged in the
said sand glass or its equivalent, or the said lever may be released or depressed by
means of clockwork or other analogous mechanism. In place of forming the
quadrant with the recess and the lever with the projection the quadrant may have
the projection formed upon it and the lever, the recess, or any other suitable "trigger
device may be applied. The oscillating or moveable outlets are each provided at
its outer or lower end with a hinged door, which, when the said outlets cant over
upon the release of the beforementioned "trigger" device, by the gravity of the
therein-contained malt, grain or other vegetable product, open and close alternately,
that of the outlet presented to the screen being closed and the other opened
automatically.
"
In place of heating the kiln in the manner herein before described, that is to say,
by a furnace at its lower part, the said kiln may be heated by steam, hot air or
their equivalent supplied from any outside source and passed through pipes situated
within the kiln.

'
I, JAMES MILNE of the firm of Milne Brothers, of the Town and County of
Aberdeen, North Britain, Grain and Produce Merchant do hereby declare the
nature of my invention for IMPROVEMENTS IN APPARATUS FOR DRYING MALT,
GRAIN, SEEDS AND OTHER ANALOGOUS VEGETABLE PRODUCTS and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
My Invention, which relates to improvements in apparatus for drying malt,
grain, seeds and other analogous vegetable products, consists of one or more screens
of wire cloth or gauze or otherwise perforated metal arranged vertically within a
kiln heated below from a furnace or furnaces, the ascending currents of heated air.
drawn upwards by a chimney, exhaust fan or their equivalents, being caused to
pass and repass amongst the descending vegetable products under treatment. Each.
of these screens (of which, for brevity, only one is hereinafter described) is composed
of two sheets of such perforated material, and the said screen is divided in the
direction of its width into two, three or more parts by vertical division plates
The perforated sides or sheets of the said screen may be arranged throughout their
entire vertical length parallel or obliquely, that is to say, nearer together at their
upper than at their lower extremities; or the said perforated sides may be arranged
parallel or obliquely for a portion of their length, the remaining portion of the
length being formed by the sides of the screen taking a zigzag course. This said
zigzag part may be either above or below the parallel or tapered portion of the
screen, or the said zigzag portion may extend the entire height of the kiln; under
any of these forms which it is caused to take, it is arranged in accordance with the
requirements of the produce which is to be dried within the apparatus. The screen
when used in the zigzag form, is provided at its angles with projecting fingers
arranged to break the descent and thereby mix and ensure the uniform drying of
the said malt, grain or other vegetable product under treatment. At the upper
extremity of the screen, hoppers and shoots are so arranged as to distribute the
grain equally throughout the width of the screen, and at the lower extremity of
the said screen an arrangement of mechanism is provided to automatically discharge
the dried malt, grain or other vegetable product into the required bins or other,
receptacles.
The mechanism employed for this purpose may consist of a roller having one or
more longitudinal grooves such as that described in my Complete Specification
No. 766 A.D. 1884 or of any other suitable apparatus, but the arrangement of
mechanism which I prefer to employ for this purpose consists of two outlets formed
of sheet iron or its equivalent and mounted upon a horizontal shaft situated
beneath the lower extremity of the perforated screen. The two outlets are
arranged upon this shaft in such manner that only one at a time can be presented
to the opening formed by the lower end of the screen, while between the two said

page_text: outlets a plate is arranged to check the descent of the grain during the time
occupied by the moving away of one, and presentation of the other outlet to the
lower or outlet end of the screen. The horizontal shaft is provided with a
quadrant, wheel or its equivalent having one, two or more notches in its edge.
These notches engage with a projection formed upon a pivoted lever or its equiva-
lent, the amount of resistance offered by which, may be adjusted by a spring or
counter-weight. A sand glass, a sand box or its equivalent is arranged upon a
horizontal shaft situated above, below or near the herein-first mentioned shaft, and
is tilted over by the action of the oscillating outlets. This sand glass or its
equivalent operates in conjunction with the before mentioned pivoted lever so as to
release the shaft carrying the outlets at any pre-arranged intervals. For this
purpose, a valve may be arranged in the said sand glass or its equivalent, or the
said lever may be released or depressed by means of clockwork or other analogous
mechanism. In place of forming the quadrant with the recess and the lever or its
equivalent with the projection, the quadrant may have the projection formed upon
it and the lever, the recess, or any other suitable "trigger" device may be applied.
The oscillating or moveable outlets are each provided at its outer or lower end with
a door, which, when the said outlets cant over upon the release of the before
mentioned "trigger" device, by the gravity of the therein-contained malt, grain
or other vegetable product, open and close alternately, that of the outlet presented
to the screen being closed, and the other opened automatically.
In place of beating the kiln in the manner herein before described, that is to say,
by a furnace or furnaces located at its lower part, the said kiln may be heated by
steam, hot air or their equivalent supplied from any outside source and passed
through pipes situated within the kiln.
In order that my Invention may be properly understood and readily carried into
effect, I will now proceed to describe the drawings hereunto annexed.
Figure 1, is a vertical section through one form of a drying kiln constructed
according to my present Invention.
Figure 2, is a similar view taken on a line at right angles to that at which
Figure 1, is taken.
Figure 3, is a horizontal section of the same taken on the line A. B, Figure 1.
Figures 4 to 13 (inclusive) are views of detached portions of the same drawn to
an enlarged scale and all hereinafter more particularly described.
Figures 14 and 15 are respectively a front elevation and a transverse section of
a detached modified portion of the same also drawn to an enlarged scale.
Figures 16 and 17 are views respectively similar to Figures 1 and 2 of another
form of drying kiln constructed according to my present Invention and drawn to
a reduced scale.
Figures 18 and 19 are horizontal sections of the same taken respectively on the
lines C, D, and E, F, Figure 17.
In constructing the drying kiln in accordance with my present Invention and as
represented more particularly at Figures 1, 2 and 3 of the annexed drawings,
I arrange the hoppers a, to discharge their contained malt, grain or other analogous
vegetable products into the upper ends of the screens which are hereinafter described
and between which, in their passage downwards the said vegetable products are
acted upon by the ascending currents of heated air or other drying medium
employed. The hoppers a, or the outlets of the said hoppers a, are provided with
means for distributing the descending vegetable product equally throughout the
width of the screens in a manner analogous to that described in my Complete
Specification No. 766 A.D. 1884. As shewn at Figure 2, of the annexed drawings
these screens are divided by the plates c, into five vertical parts all of which parts
however are supplied with the vegetable product to be therein dried, through one
common inlet and discharge the said product, when dried, through one common
outlet as hereinafter more particularly described. The upper part of the before-
mentioned screens are preferably constructed in the manner indicated more
particularly at. Figure 2, that is to say, inclining inwards towards the centre of

page_text: the drying kiln. At these parts the screens are formed, at one side with the
sheets d, of wire cloth or its equivalent arranged obliquely and connected together
by the vertical or nearly vertical strips e, of perforated or unperforated sheet iron,
the wire cloth d, and sheet iron e, being secured in any convenient manner to the
vertical division plates c. The opposite or lower sides of the said screens at their
upper parts are formed with the sheets f, of wire cloth or its equivalent, these
being supported in guides which admit of their being readily withdrawn from
time to time, that is to say, when access to the interior of the screens is required
for cleaning or for other purposes. The lower edge of each of the sheets f, of wire
cloth is arranged so as to overlap. the upper edge of the sheet f, immediately below
it, and space is left between these two overlapping portions so that the ascending
currents of heated air or other drying medium employed, may readily pass between
and through the perforated portions d, of the screens on their passage outwards
from the kiln. The hereinlast described portions, that is to say, the upper portions
of the screens are connected at their lower ends to the zigzag portions now to be
described. These lower or zigzag portions are formed of two sheets g, of wire
cloth or its equivalent arranged parallel to each other and secured at their edges in
any convenient manner to the vertical division plate c, and at the angles of the
said screens, the strips 82, (Figures 2 and 3) of wire cloth or its equivalent are
so arranged as to project and present to the descending grain alternately one such
strip 82, and immediately below it a space formed between two such strips, that is
to say, substantially in the manner described in my aforesaid Complete
Specification. These division plates c, are supported by their lower edges resting
upon iron girders or joists built into the walls of the kiln, that is to say, in the
manner described in my aforementioned Complete Specification No. 766 A.D. 1884;
or the said plates may be supported in any other convenient manner such for
example, by the brackets b, shewn at Figures 1 and 2. At or about half way up
the drying kiln I provide the joists or girders h, which support the arch i, and
which, with the horizontal doors j, and inclined plates k, (Figure 1) divide the
central compartment of the kiln into an upper middle and lower middle
compartment. The inclined plates k, are rigidly secured in any convenient
manner upon the vertical division plates c, while the doors j, for the removal of
any accumulated dust or dirt, are capable of being turned by means of the
levers m², (Figure 2) or their equivalents situated at the outside of the walls l,
and m, into the position indicated in dotted lines at Figure 1.
The walls n, of the kiln are formed with the vertical passages o³, the lower
ends of which are connected through the flue tubes p³, (Figure 1) with the upper
part of the furnace c, and the upper ends of the said passages are provided with
sliding doors or dampers, by opening which, highly heated air is conducted
directly from the furnace c², to the upper part of the kiln that is to say,
substantially in the manner described in my aforesaid Complete Specification
No. 766 A.D. 1884.
Below the lower extremities of the zigzag screens g, there is arranged the
apparatus by which the dried grain is intermittently discharged. This apparatus,
as represented more particularly at Figures 4 to 13 (inclusive) of the annexed
drawings, consists of the two outlets n, and o, which are, or may be formed of
sheet iron and which are secured rigidly upon the horizontal shaft p. Between
the upper orifices q, of these outlets n, and o, there is provided the curved plate r,
which serves to support that dried grain or other analogous vegetable product
which is in the zigzag screens g, at the time when the outlets n, and o, are in
motion as hereinafter described. The discharge orifices of the outlets n, and o, as
represented more particularly at Figures 4, 5, 8 and 9 are held apart by the stays 8,
which are secured to the angle iron t, and the said outlets, at these parts are
provided with doors which are caused to open when the said outlets n, and o, have
arrived at their discharging position. These doors, as is obvious, may be
constructed and be caused to operate in many different ways and as an example,
upon the annexed drawings I have represented such doors as being arranged to

page_text: slide in a direction transverse to their length. These said doors u, as shewn on.
an enlarged scale in front elevation at Figures 10 and 11, and in transverse
sections at Figures 12, and 13, are held in position, that is to say, close against
the discharge ends of the outlets n, and o, by the nuts v, which are screwed upon
the screwed studs w, or their equivalents, the said studs, being secured in the
brackets. These brackets are riveted or otherwise secured at the interior of the
outlets n, and o, and the studs w, besides passing through the doors u, also pass
through the levers y, which are pivoted at 2, upon the said doors. The doors u,
are slotted at a', so that they may, at these parts, move upwards past the fixed
pivots w, into their open position as indicated at Figures 11 and 13. The opening
of the doors u, is effected by moving the levers y, into the position in which they
are represented at Figure 11. The levers y, may be so operated, by means of
rigid stops against which the said levers are caused to strike when the outlets n,
and o, are moving over into one or other of their two positions, or the said levers y,
as represented upon the annexed drawings, may be provided with the studs b¹,
which project outwards so that their respective paths are intersected at the proper
point by the rigid stops c¹. These stops c', are secured to any convenient part of
the kiln for example those for operating the levers y, at the ends of the doors u,
may be built into the walls of the said kiln and those stops for operating the
levers y, at or near the centre thereof may be secured to the vertical division
plates c, all as shewn more particularly at Figure 4, it being here explained that
any number of levers y, proportionate to the size and weight of the doors u, may
be employed.
In place of constructing the outlets n, and o, in the manner hereinbefore set
forth and thereby causing the doors thereof to be opened by means of levers, I may
arrange the said doors to be opened by means of cams or cam surfaces such as those
represented at Figures 14 and 15. Under this arrangement, the sliding doors u,
are supported against the inner or under sides of the outlets n, and o, by means of
the brackets q, in which brackets the said doors are free to slide transversely. At
their two ends, and if required at their centre, the doors u, carry the rollers ³,
which are so situated that they roll upon the cams or cam surfaces s², and in so
doing, cause the doors u, to be raised and thereby leave the contents of the said
outlets n, and o, free to fall into the shoots b², Figure 2. The bars upon which the
cams, are formed, are preferably secured by the bolts and nuts t2, or their
equivalents, to the brackets b.
For automatically canting over the outlets n, and o, into the positions necessary
for ensuring that one is being charged with grain or its analogue while the grain or
other analogous vegetable product is being discharged from the second outlet, there
may be provided an arrangement of mechanism operated by clockwork, or by a
sand glass or by the equivalent thereof.-The arrangement of mechanism however,
which I prefer to employ for the aforementioned purpose is that which is
represented on an enlarged scale at Figures 4, and 7, of the annexed drawings
the said apparatus being there represented, in side elevation, when respectively in
its "locked" and "unlocked" condition as hereinbefore explained.-At Figures 5,
and 6, respectively this said apparatus is represented in front and back elevation
when in its unlocked condition, while at Figures 8, and 9, respectively I have
represented the same in front elevation when locked in its two positions, that is to
say, at Figure 8, it is represented in the position in which one of the outlets is
being charged with dried grain or other analogous vegetable product and at Figure 9,
the said apparatus is represented with its other or second outlet being so charged.
In applying this apparatus to the outlets n, and o, the shaft p, upon which the said
outlets are rigidly carried, passes, as shewn at Figures 2 and 4, outwards through
the walls of the kiln.-In these walls the said shafts p, are supported in bearings
(not represented on the annexed drawings) and on one end thereof the wheel d',
is keyed or otherwise secured. In the edge of this wheel d', there are formed the
two recesses e¹, of size sufficient to admit the stop f¹. This stop f¹, is secured to
the vertical bar g³, which is capable of being moved in the direction of its length

page_text: within its guides h¹, which are formed at the back of the plate i¹, and passing
through a slot in the said plate ¹, the stop is also capable of being raised and
lowered. The bar g¹, is moved downwards, for releasing the stop f¹, from the
recesses e¹, by means of the cam j, which is secured upon the horizontal shaft k¹,
and which is rotated by means of a water or other liquid containing vessel herein-
after described. The upper end of the bar g', is maintained in contact with the
surface of the cam 1, by means of the weight m¹, the position of which, is
adjustable upon the lever -This lever n', is pivoted at o¹, to the back of the
plate , and is connected to the bar g', by a pin p¹, which is secured thereto,
engaging with a slot formed in the said lever n¹. The plate i¹, is secured to.the
outside of the wall m, of the kiln, by bolts or the equivalents thereof passing
through the holes q', the said plate being formed with the projecting edger,
Figures 4, 6, and 7.-The water or other liquid-containing vessel hereinbefore
referred to, is formed in two parts s', and t₁, which are united by the central
portion u¹, by which central portion, the said vessel is secured to the shaft k¹.-
Through this central portion u', there is formed a passage communicating with the
two parts s¹, and t¹, and the said passage is provided with a valve which is operated
by the screw v¹, so that the water or other liquid passing from the vessel s¹, to the
vessel t¹, or vice versa, may be caused to flow quicker or slower as may be desired.--
The vessels s¹, and t¹, are further connected by the tube w¹, which admits of the
air passing from one to the other of such vessels. At the back of the vessel s³,
there is secured the segmentally-grooved projection 21, in the groove of which a pin
or anti-friction roller y¹, is free to move.-This pin or roller y¹, which is represented
in dotted lines upon the annexed drawings, is secured to the upper end of the
rod, the lower end of which is pivoted at a³, to the rim of the wheel d'.
In the hereinlast described automatic discharging apparatus the periods at which
the grain or other analogous vegetable product is so caused to be discharged, inay
be regulated by adjusting the valve v', or by adjusting the position of the
weight m', on its lever n¹. Let it be supposed that the outlets n, and o, are in
the position indicated at Figure 8, of the annexed drawings that is to say, the
outlet n, is receiving the grain falling from the zigzag, parallel or oblique screens,
and that the vessels s', and t', are also in the position there indicated.-During
the time the grain is so directed, the water or other liquid is flowing from the
vessel 8, into the vessel t¹, and so soon as sufficient of the said liquid has passed
from the then upper to the lower of such vessels, the said vessels commence to
move in the direction indicated by the arrows at Figure 8.-This motion continues
until the vessels 81, and t¹, arrive at the respective positions in which they are
shewn at Figures 5, 6, and 7, that is to say, until such time as the pin or
anti-friction roller y', abuts against the lower end of the segmental groove x¹..
By the rotation thus imparted to the cam 1, the bar g¹, is depressed, and with it
the stop f, so that the weight of the grain or other analogous vegetable product
then contained within the outlet n, being left unsupported causes the said outlet n,
to descend, and the door u, thereof to be opened in the manner herein before
described and thereby allows the said grain to fall into the shoots 62, Figures 1
and 2. Having completed these operations, the second outlet that is to say, the
outlet o, is brought into its charging position and the several parts of the releasing
apparatus assume the respective positions indicated at Figure 9, of the annexed
drawings. The water or other liquid is then caused to flow from the vessel t¹, to
the vessel 8, and the said vessels, after sufficient of the liquid has so passed,
commence to travel in the direction indicated by the arrows at Figure 9, until such
time as the upper end of the segmental groove x abuts upon the pin or anti-
friction roller y¹. By the rotation thus imparted to the cam j¹, the weight of the
grain then contained within the outlet o, is, in the manner herein before described,
left unsupported and thereby causes the discharging apparatus to return to the
position indicated at Figure 8, and the door u, of the outlet o, having been opened
during its travel to such position, allows the grain or other contents of the outlet o,
to fall into the shoot 6 as before described.

page_text: In the general arrangement of the drying kiln, the working is conducted as
follows: A fire is kindled at the furnace c², or, it may be furnaces, formed in the
lower part of the kiln, and the currents of heated air ascending therefrom pass in
the direction indicated by the arrows at Figure 1, outwards through the zigzag
or otherwise formed lower portions g, of the screens wherein they impinge upon
the descending vegetable product under treatment, and the heated air also passes
up into the arch i, the temperature of which is thereby raised to a very con-
siderable extent.-The ascending currents of heated air then strike inwards through
the upper part of the screens and thence through the flue d', from which they escape
through the chimney e². If desired, highly heated air may also be passed direct
from the furnace c², to the upper part of the kiln by means of the passages o³, and
flue tubes p², that is to say, in the manner hereinbefore described with reference
more particularly to Figure 1, of the annexed drawings.-The flue d², is provided
with the pivoted damper f, which may be operated by means of the lever l¹,
(Figure 2) from the outside of the kiln and thereby enables the draught through
the said kiln to be readily controlled. The walls of the kiln are provided with
the manholes g², by means of which, easy access may be had to the interior of the
said kiln, when such is desired for cleaning or other purposes and the said kiln is
further provided with any suitable form of indicator for indicating the heat or
temperature at the interior thereof.
As has been herein before described the grain or other analogous vegetable
product to be subsequently treated within the drying kiln, descends from the
hoppers a, into which however, the said product may be first charged in any
desired manner. The arrangement represented at Figures 1 and 2 of the annexed
drawings for charging the hoppers a, is that wherein is employed the elevator l²,
to which the grain or other vegetable product is supplied at any convenient part,
the elevator discharging its contents through the shoot 2². After having passed
down through the kiln and been discharged therefrom into the shoots b³, by the
outlets n, and o, in the manner herein before described, the dried grain may be
conducted through further shoots and if necessary by screw creepers or conveyors
or the equivalents thereof to the elevator 2, and by it, be discharged through the
shoots 2, into the dry-corn bins 3, or the said dried grain may be conducted to
any other desired receptacles.
In the arrangement of apparatus which I have represented at Figures 16 to 19,
inclusive, there are employed two furnaces c³, and one of the perforated screens
there shewn is constructed in a manner similar to that shewn at Figures 1 and 2
of the annexed drawings while the other of such screens is constructed of a zigzag
form throughout its whole vertical height.-Under this arrangement the elevators q²,
and 72, are so situated at the sides of the kiln as to discharge the grain directly
into the hoppers a, which are inclined over so as to dispense with shoots or other
spouts. In other details the kiln represented at Figures 16 to 19, corresponds
with that herein before described and shewn at Figures 1, 2 and 3 of the annexed
drawings and therefore need not be herein further described.
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
