I GEORGE EDDISON STEAD of Skinner Lane Works, Leeds in the County of York,
Linen Manufacturer do hereby declare the nature of this invention to be as follows:-
My invention relates to belting and consists in improved combinations of material
for the manufacture of belting, the belts made on my improved plan being more
particularly intended for elevator belts but also applicable to other purposes. Many
manufacturers, especially flour millers and dyers are put to much inconvenience in
consequence of the variations in length of their belts caused by changes in the
humidity and temperature of the atmosphere and by water and steam. The object of
my improvements is to produce belts that will not stretch nor be affected by said
changes and influences while retaining the required pliability, which 1 effect in the
following manner :
I first manufacture a belt woven with a combination of metallic and fibrous threads,
part of the warp threads being of metallic wire, by preference phosphor bronze or
silicium bronze wire and the remaining warp threads and the weft being fibrous
threads. These wires are made indented or roughened so that they will not draw or
work out after being woven into the belt. By preference I use cotton threads or the
fibrous threads, but hemp, jute, hair or any other fibrous material ordinarily used for
weaving belts may be employed. The wire threads I usually place one quarter to three
eighths of an inch apart over the width of the belt but they may be closer or farther
apart suitably to the strain the belt will be subject to when in use. I make the wire
threads of such thickness and put such tension upon them in the loom that they
remain perfectly straight in the woven belt and are not wavery or bent alternately
over and under the weft as in the ordinary method of weaving. I then place the
wired belt produced as herein before described between a fibrous woven fabric. By
preference I use woven cotton "duck" and lap it round the belt in several folds or
layers, but other fabrics ordinarily used for sewn fibrous belting may be employed.
In some cases I place one or more belts woven of fibrous materials and of the same
width as the belt woven with wires on each side of the latter. Upon one side of the
combined belt I place a facing which by preference is of leather. In some cases I

sufficiently wide to allow the edges being turned over to the back of the belt so that
when the whole is fixed together the combined belt has leather edges and is thereby
prevented from fraying at the edges. I then sew the different fabrics or layers
together with several rows of stitches in the width of the belt or rivet them or do
both.
In some cases I omit the facing herein before described and form the belts of the
belt woven with wires and the fibrous fabric only.
The fibrous part of the belts may be impregnated with linseed oil, paint, tar or any
other substances ordinarily used for impregnating fibrous belts to render them
waterproof.

Improvements in Belting.
I GEORGE EDDISON STEAD of Skinner Lane Works, Leeds in the County of York,
Linen 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 :-
My invention relates to belting and consists in improved combinations of materials
for the manufacture of belting, the belts made on my improved plan being more
particularly intended for elevator belts but also applicable for other purposes. Many
manufacturers, especially flour millers and dyers are put to much inconvenience in
consequence of the variations in length of their belts caused by changes in the
humidity of the atmosphere and by water or steam. The object of my improve-
ments is to produce belts that while retaining the requisite pliability will not stretch
nor be affected by said changes and influences in the same way as ordinary belts,
which I effect by insertion during the process of manufacture a row of straight
longitudinal metal wires into the belt distributed evenly over its width.
The wires are inserted into the belt by the following process of manufacture. I
manufacture a belt woven with a combination of metallic and fibrous threads part of
the warp threads being metal wires, by preference phosphor bronze or silicium bronze
wires, and the remaining warp threads and the weft being fibrous threads. The wires
may be round or flattened and are mado roughened or indented, which may con-
veniently be done by means of milling them, so that they will not draw or work out
after being woven into the belt. By preference I use cotton threads for the fibrous
threads, but hemp jute hair or any other material ordinarily used for weaving belts
may be employed. I usually place the wire threads one quarter to three-eighths of an
inch apart over the width of the belt, but they may be closer or further apart suitably
to the strain the belt will be subject to when in use. I make the wire threads of such
thickness and put such tension upon them in the loom that they remain perfectly
straight in the woven belt and are not wavey or bent alternately over and under the
weft as in ordinary weaving.
In some cases I weave the belt in the manner herein before described of sufficient
thickness to be suitable for the purpose it is intended for by using thick or double or
multiple fibrous warps, in which the wire threads become embedded or enclosed.
In some cases 1 place a thin belt woven as herein before described between fibrous
woven fabrics. By preference I use woven cotton "duck" and lap it round the belt in
several folds or layers, but other fabric ordinarily used for sewn fibrous belting may
be employed. In some cases I place one or more belts woven of fibrous materials
and of the same width as the belt woven with wires on each side of the latter. Upon
one side of the combined bolt I place a facing which by preference is of leather and
made slightly wider than the belt. I then sew the different fabrics or layers together
with several rows of stitches in the width of the belt or rivet them or do both.
In some cases I omit the facing herein before described and form the belts of the
belt woven with wires and the fibrous fabric or fabrics only.

page_text: The fibrous part of the belt may be impregnated with linseed oil, paint, tar, or any
other substance ordinarily used for impregnating belts to render them water-proof.
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
Firstly. The insertion of straight wires into belts made of fibrous material, sub-
stantially as herein before described and for the purpose set forth.
Secondly. The manufacture of belts with straight wires inserted into them,
substantially as herein before described and for the purpose set forth.
Thirdly. The combination of belts woven with wires inserted into them with other
fibrous fabrics into one belt with or without leather facings.
