A New or Improved Wire Plate or Grating to be Employed in the
Drying of Grain, Malt, Seeds, or other Analogous Vegetable
Products.
L, JAMES MILNE of the Town and County of Aberdeen, North Britain, Grain and
Produce Merchant do hereby declare the nature of this invention to be as follows:-
This Invention which relates to a new or improved wire plate or grating to be
employed in kilns or other apparatus used for the purpose of drying Grain, malt,
seeds or other analogous vegetable products, consists as follows.
In carrying out this invention the said wire plate or grating is composed of steel or
other metal wires placed parallel to each other at equal short distances apart. Those
parallel longitudinal wires are by preference made triangular their cross section being
a triangle with the base uppermost, the spaces between the wires having a similar
cross section, but with the triangle reversed, the apex being above, and the base below.
The said parallel longitudinal wires are joined together by a number of transverse
bars, or ribs of a triangular form, having the base uppermost, but they may be made
of any convenient section such as oval or square, placed at suitable distances apart
with the under surface projecting below the bottom of the parallel longitudinal wires,
the upper surface of the wire plate or grating being flat forming a smooth level
surface suitable for the reception and working of the article to be operated upon.
The parallel longitudinal wires and spaces may be made narrow or wide to suit the
malt Grain, seeds or other products under treatment. The before mentioned
longitudinal parallel wires are by preference made triangular as that form is best
adapted to allow any particles passing through the openings to fall away quickly from
the wire plate or grating and thereby give a free air passage through it, to the article
under treatment or manipulation, but I do not confine myself to making the said wires
of a triangular section, as they may be made of any other suitable form, such as oval
or square, the openings between necessarily varying in form to suit.
The parallel longitudinal wires are preferably made of steel, drawn to the required
shape or form-but they may also be made of iron or other suitable metal.

page_text: The transverse bars or ribs are also preferably made of steel, but they may also be
made of iron or other suitable metal, and cast on to the back or lower side and between
the parallel longitudinal wires. The foregoing may be accomplished by placing the
parallel longitudinal triangular or other shaped wires in a frame or trough having
parallel longitudinal spaces formed by division plates or their equivalents, those division
plates deciding the distance to be left between the parallel longitudinal wires and
necessarily varying in thickness according to the space required between the said parallel
longitudinal wires and their length, depending on the distance between the transverse
bars or ribs. When the parallel longitudinal wires are thus placed in position the
transverse bars or ribs are cast in the ordinary method on the back and between the
parallel longitudinal wires, thus binding them together and forming the wire plate or
grating hereinbefore described. I do not however confine myself to this particular
mode of making the wire plate or grating, or to any particular method.
The wire plate or grating may be made of any convenient size required, and
preferably flat, but it may be made curved.
The wire plate or grating when employed as floors to ordinary flat kilns used for
the purpose of drying malt, grain, seeds, or other products are placed close to each
other the projecting transverse bars or ribs resting on the upper side of the ordinary
floor-plate bearers, the wire plates being connected to each other by staples or other
equivalent means affixed to the lower sides of the transverse ribs or bars at convenient
intervals, expansion and contraction being allowed for between the extreme outer
edges of the wire plate or grating, and the kiln walls.

Drying of Grain, Malt, Seeds, or other Analogous Vegetable
Products.
I, JAMES MILNE of the Town and County of Aberdeen, North Britain, Grain and
Produce Merchant, 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 which relates to a new or improved wire plate or grating to be
employed in kilns and other apparatus used for the purpose of drying Grain, Malt,
seeds or other analogous vegetable products, consists as follows-
The said wire plate or grating is composed of steel or other metal wires placed
parallel to each other at equal short distances apart. Those parallel longitudinal wires
are by preference made triangular, their cross section being a triangle with the base
uppermost, the spaces between the wires having a similar cross section, but with the
triangle reversed, the apex being above and the base below. The said parallel
longitudinal wires are joined together by a number of transverse bars or ribs pre-
ferably of a triangular form having the base uppermost, but they may be made of any
convenient section such as oval or square. These transverse bars or ribs are placed
at suitable distances apart with their under surfaces projecting below the bottom of
the parallel longitudinal wires, the upper surface of the wire plate or grating being
flat forming a smooth level surface, suitable for the reception and working of the
article to be operated upon. The parallel longitudinal wires and spaces may be made
narrow or wide to suit the malt, grain, seeds or other products under treatment.
The beforementioned longitudinal parallel wires are by preference made triangular
as that form is best adapted to allow any particles passing through the openings to
fall away quickly from the wire plate or grating, thereby giving a free air passage
through the plate to the article under treatment or manipulation. I do not confine
myself to making the said wires of a triangular section, as they may be made of any other
suitable form, such as oval or square the openings between necessarily varying in
form to suit.
The parallel longitudinal wires are preferably made of steel drawn to the required
shape or form, but they may also be made of iron or other suitable metal.
The transverse bars or ribs are also preferably made of steel, but they may also be
made of iron or other suitable metal and cast on to the back or lower side, and between
the parallel longitudinal wires—The foregoing may be accomplished by placing the
parallel longitudinal triangular or other shaped wires in a frame or trough having
parallel longitudinal spaces formed by division plates or their equivalents, those division
plates deciding the distance to be left between the parallel longitudinal wires and
necessarily varying in thickness according to the space required between the said
parallel longitudinal wires, and their length depending on the distance between the
transverse bars or ribs. When the parallel longitudinal wires are thus placed in
position the transverse bars or ribs are cast in the ordinary method on the back and
between the parallel longitudinal wires, thus binding them together, and forming the
wire plate or grating hereinbefore described. I do not however confine myself to
this particular mode of making the wire plate or grating or to any particular
.method.
The wire plate or grating may be made of any convenient size required, and
preferably flat, but it may be made curved.

page_text: The wire plate or grating when employed as floors to ordinary flat kilns used for
the purpose of drying malt, grain, seeds or other products are placed close to each
other, the projecting transverse bars or ribs resting on the upper side of the ordinary
floor-plate bearers, the wire plates being connected to each other by staples or other
equivalent means, affixed to the lower sides of the transverse ribs or bars at convenient
intervals expansion and contraction being allowed for between the extreme outer
edges of the wire plate or grating and the kiln walls.
In order that my said Invention may be properly understood and readily carried
into effect, I will now proceed to describe the drawings hereunto annexed.
Figures 1 and 2 are transverse sections, Figure 3a plan and Figure 4, a longitudinal
section at natural size of a portion (a corner) of the new or improved wire plate or
grating, constructed according to and constituting my present Invention. Figures 1
and 2 represents respectively the parallel longitudinal bars with a triangular and
elliptical cross section.
Figure 5, shews one mode of attaching two contiguous plates together when
employed as floors to ordinary flat kilns, whilst a second method of attachment is
represented at Figures 6 and 7, which are respectively a transverse and a longitudinal
section of the floor plates and their supports.
My new or improved wire plate or grating consists of a series of steel or other
metal wires A, placed parallel to each other at equal short distances apart. The said
parallel longitudinal wires A, are by preference made triangular as represented at
Figures 1, 5 and 6, but they may have any other cross section, elliptical for example,
as shown at Figure 2, the space B, between the bars A, necessarily varying in form
to suit the different sections. The beforementioned longitudinal wires A, are joined
together by a number of transverse bars or ribs C and C¹of any convenient section,
but preferably either square as shewn in Figure 7, or the section of the intermediate
bars C, may be an irregular hexagon, and the end transverse bar C¹, an irregular
pentagon as represented in Figure 4,-These transverse bars C and C are placed at
suitable distances apart with their under surfaces projecting below the bottom, and
their upper surfaces flush with the top of the longitudinal wires A.
The plates when employed as floors to ordinary flat kilns used for the purpose of
drying malt, grain, seeds or other products, are placed close to each other, the pro-
jecting transverse bars or ribs C and C, resting on the upper side of the ordinary
floor plate joists D, which are in turn carried by bearers E, and the whole supported
on metal standards F, as represented in Figures 6 and 7. The said plates are
connected to each other by staples G, Figure 5, or by junction plates H,-Figures 6
and 7, affixed by screw pins or otherwise to the lower sides of the transverse bars or
ribs C and C, at convenient intervals.
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
As an improvement in wire plates or gratings, employed in the drying of grain,
malt, seeds or other analogous vegetable products, the combination of parallel longi-
tudinal wires A and transverse bars C and C, the said bars C and C³, being cast on
the back, and in between the wires A, in such a manner that the upper surfaces of
wires A, and bars C and C, are level, substantially as hereinbefore described, and for
the purpose specified with reference to the annexed drawings.
Dated this 25th day of October 1887.
