PROVISIONAL SPECIFICATION.
Improvement in or relating to Travelling Creepers for Use in
Cotton-opening and other Machinery.
We, Sir ELKANAH ARMITAGE & SONS, LIMITED, Manufacturers, and PHILIP
DUNKERLEY, Manager, all of Pendleton, near Manchester, in the County of Lancaster,
do hereby declare the nature of this invention to be as follows:-
This invention relates principally to the manufacture of a cloth to be used for what
are known as "seed extractors" in machinery for opening cotton, but the same cloth
may be used with advantage for other similar "creepers," or "traversing bands" and
is recommended on account of its novelty, adaptability and utility.
Hitherto a plain cloth has been used for making the "seed extractor," the trans-
verse laths or blades being nailed or fixed thereto and the whole lattice being
strengthened beneath the cloth by strips of leather running the entire length of the
band; these strips of leather being screwed to the laths or blades through the
cloth.
Our invention is intended to dispense with the necessity for these strengthening
strips of leather and for this purpose we weave a cloth having one or more longi-
tudinal bands of much thicker and stronger texture than the rest of the cloth.
This improved cloth will form a more useful "seed extractor" "
or creeper" than
when leather strips are used to strengthen the same, because the expense and labour
of applying leather strips is avoided.
The strengthening strips also being continuous and forming a component part of
the fabric, there will be no joints, as there are necessarily in leather which is limited
in length, and therefore there will be no liability to wear loose and uneven at such
joints.
Improvement in or relating to Travelling Creepers for Use in
Cotton-opening and other Machinery.
We, Sir ELKANAH ARMITAGE & SONS, LIMITED, Manufacturers, and PHILIP
DUNKERLEY, Manager, all of Pendleton, near Manchester, in the County of Lancaster,
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 principally to the manufacture of a cloth to be used for what.
are known as "seed-extractors," (i.e. creepers which work in the dust trunks of

machinery for opening cotton,) but the same cloth may be used with advantage for
other similar " creepers or traversing bands" and is recommended on account of
its novelty, adaptability, and utility.
Hitherto a plain cloth has been used for making the "seed extractor
"
or creeper
the transverse laths or blades being nailed or fixed thereto, the whole lattice being
strengthened beneath the cloth by longitudinal strips of leather running the entire
length of the band; these long strips of leather being screwed to the laths or blades
through the cloth.
Our invention is intended to dispense with the necessity for these long strengthen-
ing strips of leather, and the nature of our said invention will be readily understood
on reference to the sheet of drawings hereunto annexed and the following explanation
thereof.
Fig. 1 is a face view, Fig. 2 an edge view, and Fig. 3 a back view of a seed
extractor or creeper made according to our improvements.
For the purposes of our invention we weave a cloth having one or more longitudinal
bands of much thicker and stronger texture than the rest of the cloth as shown at a
on Figs. 1 and 3 of the drawings.
This we propose to effect by introducing at these parts of the cloth where the bands
are required an increased number of warp threads, or warp threads of a greatly
increased strength or thickness, or both, and lacing the same together by the weft
threads, or by binding warps, or by both, in the manner well known to weavers.
The transverse laths or blades bare fixed to the canvas by nails c and screws d
passing through the cloth or canvas, and to prevent the heads thereof being pulled
through the canvas we prefer to employ short washers or short pieces of leather or
.other material as shown at e.
"
This improved cloth will form a more useful "seed-extractor 66
"than
or creeper
when long leather strips are used to strengthen the same, because the expense and
labour of applying the leather strips is avoided.
The strengthening strips a being also continuous and forming a component part of
the fabric there will be no intermediate joints, as there are necessarily in leather
which is limited in length, and therefore there will be no liability to wear loose and
uneven at such joints.
.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
. claim is
The improvements in or relating to travelling "creepers " for use in cotton opening
and other machinery, consisting in the manufacture and use for such purposes of a
cloth or canvas woven with longitudinal bands of much thicker or stronger texture
than the rest of the cloth, so that when nailing or otherwise fixing the transverse laths
or blades thereto, the usual longitudinal strengthening bands of leather may be
dispensed with, substantially as herein before described and illustrated by the drawings
annexed.
