Improvements in Driving and Carrying Belts and in the
Manufacture thereof.
We, ROBERT KERR and TOM JUBB, of the firm of Kerr & Jubb, of Square
Road, Halifax, in the County of York, Merchants, and FRANK REDDAWAY, of
Cheltenham Street, Pendleton, Manchester, in the County of Lancaster, Woven
Belting and Hose Manufacturer, do hereby declare the nature of this invention
to be as follows:-
Our invention relates to driving belting composed of woven material such as
canvas, duck, or other woven fabrics suitable for the purpose.
The invention relates particularly to belting made by folding the said woven
material into two or more layers of the required width and stitching the said layers
together so as to form belting of the requisite thickness and strength. In weaving
fabrics suitable for use in the manufacture of such belting it has been proposed to
incorporate soft steel or iron or other metallic wire in the warp so as to prevent
stretching when the fabric has been made into a belt. This mode of introducing
metallic wire in the warp is subject to certain disadvantages, chief among which
are the liability of the wires to cut the weft in the process of weaving and while the
belt is in use; and also a disadvantage which arises in folding the fabric into
layers, one or more of the wires sometimes appearing just at the edge of the fold.
According to our invention we use canvas or other suitable fabric woven in the
ordinary manner and from the usual materials, but in the course of making belting
therefrom, we add to the belt strands of metallic wire or other strengthening
material without actually incorporating the same in the fabric. We place the said
strengthening strands of wire or other material between the folds or layers and
preferably between the rows of stitching, whereby the layers are held together.
The addition of the said wire or other strands is preferably effected during the
stitching operation, and for this purpose in connection with the sewing machine
used for stitching the layers we employ a finger or guide which projects between
the layers of the folded belt as it is fed to the needle.
The extremity of the said finger or guide projects a little past the needle and
terminates in a groove and eye. The finger also carries a tension-fitting, and the
wire which is fed from a coil or bobbin passes first through a hole in the inner end
of the finger, thence through the tension brake, and thence to the eye at the end of
the finger, by which means the wire is laid between the rows of stitching as the
stitching proceeds. Each strand of wire or other material is thus enclosed and
imprisoned between the several rows of stitching and is thus immovably incorporated
with the belting. The finger or guide is made adjustable so as to suit any desired
pitch between the stitches.
Instead of introducing one strand of wire or other strengthening material
between each row of stitching we might introduce two or more and we might vary
the number of strands introduced into the respective layers, or at different points
in the breadth of the belt, for example, we might introduce a greater number of
strands at or near the margin than in the centre of the width. The improved
means for laying the strands of wire between the rows of stitching as hereinbefore
described might be used in the manufacture of belting made from other than
woven material and composed of two or more layers of such material stitched
together.
Lengths or strands of wire or other material may also be inserted between layers
of tanned or untanned leather; also between layers of india-rubber and cotton

page_text: canvas or fibre; or gutta-percha and cotton canvas or fibre; dermatine and linen
or cotton fibre or fabric; canvas and balata; woven canvas and camel hair or other
animal fibre.
Belting with wire or other strands introduced as set forth is or may be treated
and finished in the usual manner, riz.: by coating or saturating the same with oil,
paint, or any other suitable or usual liquid compound or dressing.

COMPLETE SPECIFICATION.
Improvements in Driving and Carrying Belts and in the
Manufacture thereof.
We, ROBERT KERK and TOM JUBB, of the firm of Kerr & Jubb, of Square
Road, Halifax, in the County of York, Merchants, and FRANK REDDAWAY, of
Cheltenham Street, Pendleton, Manchester, in the County of Lancaster, Woven
Belting and Hose 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 :-
Our invention relates to driving belting composed of woven material such as
canvas, duck, or other woven fabrics suitable for the purpose. The invention
relates particularly to belting made by folding the said woven material into two or
more layers of the required width, and stitching the said layers together so as to
form belting of the requisite thickness and strength. In weaving fabrics suitable
for use in the manufacture of such belting, it has been proposed to incorporate soft
steel or iron or other metallic wire in the warp so as to prevent stretching when the
fabric has been made into a belt. This mode of introducing metallic wire in the
warp is subject to certain disadvantages, chief among which are, the liability of
the wires to cut the weft in the process of weaving and while the belt is in use;
and also a disadvantage which arises in folding the fabric into layers, one or more
of the wires sometimes appearing just at the edge of the fold.
According to our invention we use canvas or other suitable fabric woven in the
ordinary manner and from the usual materials, but in the course of making belting
therefrom, we add to the belt, strands of metallic wire or other strengthening
material, without actually incorporating the same in the fabric. We place the said
strengthening strands of wire or other material between the folds or layers and
preferably between the rows of stitching whereby the layers are held together.
Instead of introducing one strand of wire or other strengthening material between
each row of stitching, we might introduce two or more, and we might vary the
number of strands introduced into the respective layers, or at different points in the
breadth of the belt; for example, we might introduce a greater number of strands
at or near the margin than in the centre of the width. The insertion of strands of
wire between the rows of stitching as hereinbefore described might be used in the
manufacture of belting made from other than woven material and composed of two
or more layers of such material stitched together.
The addition of the said wire or other strands is preferably effected during the
stitching operation.
Belting with wire or other strands as set forth is or may be treated and finished
in the usual manner, riz. :—by coating or saturating the same with oil, paint, or any
other suitable or usual liquid compound or dressing.
Having now particularly described and ascertained the nature of our said,
invention, and in what manner the same is to be, performed, we declare that what
we claim is :-
In the manufacture of woven driving belts, the insertion of wire or other

page_text: strengthening strips within the layers of the belt and between the rows of stitching,
substantially as described herein.
