PROVISIONAL SPECIFICATION,
Improvements in the Manufacture of Covers for use on Polishing
Rolls and the like.
We, SAMUEL DALBY, WILLIAM TACEY DALBY and HENRY SEWELL of the
Leadenhall Works, Spittlehouse Street, Leicester in the County of Leicester
Elastic Web Manufacturers do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in the manufacture of covers for use on
polishing rolls and the like used for polishing the heel, waist or forepart in the
process of finishing boots and shoes or other articles. And consists in weaving a web
of the desired width having a thickened portion that is to say; the central portion
of the web is of additional thickness to the sides or transverse ends of the web
which are of the ordinary texture, such thickened portion serving as a pad. We
also employ means for securing the piece of web after it has been cut to the length
desired to cover the surface or circumference of a roll fixed on a revolving shaft
and driven in the usual way for the purpose above stated.
To carry out our invention the web is woven from "warp and weft" preferably
of cotton or flax threads or of some such fibrous material, the centre of the warp of
the width to form the padding surface is composed of additional warp threads
coming on the rubbing face of the web (as many as may be desirable). Upon
threading the warp threads through the battens several dents near the outside edges
are left unthreaded, so that the weft threads are loose to allow running or drawing
tapes or cords to be threaded through by a bodkin or other suitable means in order
that the cover can be drawn on and secured to the bosses of the roll, by securing
the tapes or cords and bringing inwards the sliding caps over the ends and secure
them by the usual means, when the roll is ready for work.
The covers now in use for this purpose are made from "Italian or Silecian
cloth "having the sides turned over and sewn down to form a casing for a drawing
thread this leaves bulky ends, aud is objectionable.
By our invention of weaving a web having a thickened portion to form a pad
and having "dents" for the insertion of the drawing tapes or cords as before
described this is obviated.
We may also knit the same in flat knitted plain or ribbed web, made on any
rotary or flat knitting frame and thicken the central portion in any well known
manner, and insert drawing tapes or cords in the outside ends of such fabric, or
leave loose loops on the edges for the reception of such drawing tapes or cords.

Rolls and the like.
We, SAMUEL DALBY, WILLIAM TACEY DALBY and HENRY SEWELL of The
Leadenhall Works, Spittlehouse Street Leicester in the County of Leicester
Elastic Web Manufacturers 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 the manufacture of covers for use on
polishing rolls and the like used for polishing the heel, waist or forepart in the
process of finishing boots and shoes or other articles. And consists in weaving a
web of any desired width preferably having a thickened portion that is to say ; the
central portion of the web may be of additional thickness to the sides or transverse
ends of the web which are of the ordinary texture, such central or thickened
portion serving as a pad. We also employ means for securing the piece of web
after it has been cut to the length desired to cover the surface or circumference
of a roll fixed on a revolving shaft and driven in the usual way for the purpose as
above stated.
That our invention may be well understood we have appended drawings showing
several kinds of web produced in an elastic web loom, and others in order to
illustrate the objects of this our invention.
Figure 1 represents a piece of twilled webbing to form the cover A, this is woven
with the twill upon the face in an elastic loom used for weaving elastic web to be
cut up into side springs in boots, shoes and other coverings for the feet..
In place of rubber warps, cord warps a, are used, and to thicken the central
portion B additional cord warps b are employed, either in single or double shuttle
work. The cord warps, and fibrous warps C being interwoven or enclosed by the
weft thread or threads D according to the number desired. The tapes E being
threaded through and through" at varying intervals a little from each edge, the
effect of which is seen at the "right hand "exposed side of Figure 5.
Figure 2 represents a piece of straight woven web A' with alternate "
warp and
weft throughout the whole width of the web with additional cord warps b and
fibrous warps C to produce the thickened portion B, the casing tapes or cords E
are threaded through the "spaces" left for them, but they may be threaded
through and through" by preference as shown in Figure 1.
66
Figure 3 is a transverse view of a thickened web which may be woven in any
other loom or frame (than an elastic loom) the alternative being that strips of any
suitable binding material may be sewn along each edge to form the casing for the
drawing tapes or cords to be threaded through for the purpose of this invention.
Figure 4 represents an upper view of a knitted piece of webbing A, one portion
of which is shown with the drawing cords E threaded through and through" cross
or mis-stitch loops or courses a² of a long length, and the right hand portion shows
cross loops a³, knitted on the web to enclose the drawing cords E for the
purpose of this invention, and
6:
Figure 5 is a view of a narrow polishing roll made of the usual felt portion b
"dotted line," the left hand side of the roll being shown closed up and fitting
against the cap 63 of the sleeve, while the right hand side shows the cover A, or
A and A' upon the roll, and the drawing tapes or cords E ready to be pulled tight
for fastening, when this is done the sliding screw cap & upon the screwed end of
the sleeve is brought over by the usual means and encloses the part shown exposed,
the "pad cover is then firm upon the roll and the latter upon its shaft 65, and
ready for use.
"
The pad cover is made to suit any width of roll employed for polishing purposes.

page_text: It is obvious that a web woven right across of one substance or thickness having
"dents" left out in threading the warps through the battens of the loom to form
casings for the running or drawing threads, tapes or cords would come within the
scope of our invention, but our aim and object is to make the web with a thickened
centre or pad of the width of the roll on to which it is put.
To carry our invention into effect the web is woven in an elastic loom from
warp and weft" preferably of cotton or flax threads, or of some such fibrous
material, the centre of the warp of the width to form the padding or polishing
surface is composed of additional warp threads a, b, c, coming only on the rubbing
face of the web (as many as may be desirable). In each example shown in the
drawings the web is woven the same all across except that the warps are thickened
on top to form the pad or rubbing surface of any substance as desired.
"
Upon reference to Figure 2. In threading the cord and fibrous warp threads
through the battens several "dents near the outside edges are left unthreaded F,
and the weft threads D are left thus free and forms casings for the running or
drawing tapes E. to be threaded through by the aid of a bodkin or other suitable
means in order that the cover can be drawn over the roll and secured thereto in the
manner shown in Figure 5 and before referred to.
'In reference to Figure 1 which represents a twilled web (only on the face) the
running or drawing tapes or cords E being threaded through from one face to
the other at intervals in the casing formed as previously described. The cord
warps or "gut" taking the place of "rubber warps."
The web may be woven in any well known pattern not only in an elastic loom,
but other looms and as shown in Figure 3 the edges secured by any suitable strips
of binding material H to form the casing for the running or drawing tapes or
cords E.
In knitting a web for this purpose in flat machines, or warp knitting machines
producing plain or ribbed work the thickened portion can be made in any of the
well known ways such as tucking, mis-stitching, splicing or accumulating loops,
known in stocking knitting for a long time.
We should knit the web from strong fibrous material other than woollen yarn,
and make selvidge edges on each side "G Figure 4" and knit loose loops across or
make mis-stitch loops a' or a' for inserting the running or drawing tapes or cords E.
Or loose loops may be made on the edges (not illustrated) to form the casing for
the drawing cords E if desirable for the purpose of this invention.
It is usual in making casings to secure the drawing threads cords or tapes in or
about the centre for bags and the like by stitching, as at I, to keep the threads,
cords or tapes E from being pulled out.
Covers now in use for polishing rolls (both wide and narrow) are made from
"Italian" or "Silecian" cloth having the side edges turned over and sewn down
to form casings for the drawing threads.
But a web of the desired width woven
in an elastic or other loom is stronger, more durable and economical besides
producing a better rubbing or polishing surface.
Having now particularly described and ascertained the nature of this our
invention and in what manner the same is to be performed, we declare that what we
claim is :-
1. A cover for use on polishing rolls and the like made from pieces of webbing
of the desired width and length, in or at the outer edges of which are left spaces
during the process of weaving, to form casings for drawing threads, tapes or cords
for the purpose herein before described.
2. In a "pad cover" for use on polishing rolls and the like the employment of
a web baving a thickened centre, or padded face, or rubbing surface obtained in
the process of weaving by additional cord and fibrous warp threads, and in
threading the warps through the battens of the loom several "dents'
are left
at or near each outside edge to form casings for running or drawing tapes or cords
to be put therein.
"

page_text: 3. A "pad cover "for use on polishing rolls and the like knitted in such a manner
that spaces are left or formed at or near each edge for the purpose of carrying
running or drawing cords or tapes in the manner substantially as described.
4. Improvements in the manufacture of covers for use on polishing rolls and
the like substantially as herein described and set forth.
