Improvements in or relating to Wire Cloth Kiln Bedding for Drying
Barley, Oats, Wheat, and other Grain.
I, JOHN CICERI SMITH of 219 High Street, Edinburgh, in the County of Mid-
lothian, North Britain, Wire Cloth Manufacturer, do hereby declare the nature
of this invention to be as follows:-
Hitherto the wire cloth has been laid upon supporting iron bars of usually
about inch round wire and spaced about 2 or 3 inches apart. It has been found
however that the cloth so supported does not keep flat and to remedy this defect I
provide the underside of the cloth with a backing of coarsely woven stout wire.
Also it has been found that at the parts where the cloth is joined, that is to say
at the seam produced by the joinings of the selvages of the web, there is an
objectionable ridge which interferes with the efficient working or scooping of the
grain, the said ridge increasing with the expansion from the heat. To remedy this
defect I cut off the ordinary selvages and lay the sheets edge to edge, and 1 tie
down the sheets to the under backing above referred to, the said arrangement
producing a flush joining of the sheets. In order to meet the contingency of
expansion and contraction, I, after trimming off the selvages, may remove one or
more of the ordinary warp wires at the edge of the sheets whereby I am enabled to
dovetail the weft or "shoot" wires into each other, and then tie down to the
under backing; or in order to meet a greater amount of expansion and contraction
I take out more of the warped wires and so curve or bend the ends of the weft
wires that they may lie under the warped wires: this arrangement also preventing
the points of the weft wires from getting bent and protruding upwards:
I may employ a similar arrangement for producing a flush joining of the sheets
of the under woven backing, the joining being preferably effected along and
immediately above one of the supporting bars.
As a substitute for the under woven backing I may employ stout iron or steel
wires say th of an inch thick, and spaced say from inch to 1 inch, running
transversely to the supporting bars, the said wires affording a strong support for
the cloth, and being laced or otherwise attached to the cloth; or the said stout
wires may be kept in position by interweaving them with twisted wire netting.
Dated this 1st day of February 1895.

Improvements in or relating to Wire Cloth Kiln Bedding for Drying
Barley, Oats, Wheat, and other Grain.
I, JOHN CICERI SMITH, of 219 High Street, Edinburgh, in the County of Mid-
lothian, North Britain, Wire Cloth Manufacturer, 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 improvements in or relating to wire cloth kiln bedding

page_text: for drying barley, oats, wheat and other grain, and has for its object to obviate the
tendency of the cloth to become uneven on its upper, surface.
Also in accordance with my invention I provide means whereby the joints formed
by the joinings of the various web selvages or edges have no upper ridge, which,
hitherto has been found a great disadvantage.
But in order that my said invention may be more readily understood and easily
carried into effect, I will proceed to describe the same with reference to the
accompanying drawings.
Figure 1 is an upper plan, Figure 2 a cross section, and Figure 3 an under plan,
showing my improved wire cloth kiln bedding.
Hitherto the wire cloth A. has been laid upon supporting iron bars B of usually
about inch diameter, said bars. B being spaced about 2 or 3 inches: apart.
It has
been found however that with such a backing the cloth A does not keep flat or
even on its surface, and to remedy this defect I interpose, between the back or
under side of the wire cloth A and the supporting bars B, a backing of coarsely
woven stout wire C. The said cloth A, bars B and backing C being retained in
position or connected to each other by binding wires D or otherwise.
Figure 1 shows my improved joint for overcoming the objection of having a
joining ridge where the selvages of the webs meet as hitherto ; said ridge interfered
with the efficient working or scooping of the grain being treated, and particularly
when the said ridge becomes enlarged according to the amount of expansion of the
metal caused by heat from furnace etc. In constructing or forming the said joint I
cut off the ordinary selvages of the wire cloth and lay the sheets A, A edge to edge
and tie them to the coarsely woven backing C by means of wire ties E; thus
forming a flush joining of the sheets, in which one or more of the ordinary warp
wires a have been removed so as to enable the sheets or weft or "shoot" wires a¹ of
same to be dovetailed into each other before being tied down to the backing C thus
affording room for expansion or contraction of the wire cloth according to the
Ι
Or I may cut off the ordinary selvages of the wire cloth so as to produce clean
cut square edges so that when the sheets are laid side by side they lie absolutely
close together and form a perfectly flush surface when the sheets are tied down to
the coarsely woven backing by means of the wire ties.
Or as a further modification to meet a greater amount of expansion or contraction
I may take out a few more of the warp wires a and so curve or bend the ends of
the weft wires a' that they may lie under the warp wires a; this arrangement thus
prevents the points of weft wires a¹ from getting bent and protruding upwards.
Also according to my present invention I may employ a similar arrangement for
producing a flush joining of the under woven backing; said joining being preferably
effected along and immediately above one of the supporting bars B.
Also as a further modification I may, in lieu of the woven backing, employ a
backing composed of stout wires about of an inch in diameter and space them say
from to 1 inch apart; said stout wires running transversely to the supporting bars,
thus affording a strong support for the cloth; said wires being laced or otherwise
attached to the cloth or they may be kept in position by interweaving them with
twisted wire netting.
As a further modification and as a substitute for the backing wire cloth above
referred to I may employ a backing composed of what is known as square (or other
shaped) mesh crimped wirework. This is manufactured in a similar manner to the
ordinary crimped diamond panelling for protecting windows and other purposes but
is preferably made square mesh.
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 I
claim is :-
1st. In wire bedding for kilns, providing the same with a backing of stout

page_text: wirework in combination with supporting rods, substantially in the manner as and
for the purposes hereinbefore described and shown in the accompanying drawings.
2nd. In wire bedding for kilns, the improved means for joining the edges of the
wire cloth, substantially as and for the purposes hereinbefore described and shown
in the accompanying drawings.
Dated this 2nd day of November 1895.
