PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Woven Belting.
We GEORGE BANHAM & COMPANY LIMITED of Pendleton Mill, Croft Street,
Pendleton, in the County of Lancaster, Woven Hose and Belting Manufacturers
and CHARLES KAY SAGAR of the same place, Secretary to the above Company,
do hereby declare the nature of this invention to be as follows :—
Our improvements relate to the belting or driving bands composed of textile
material woven in such a manner as to produce a material of a thickness suitable
to the intended use of the belting as is well understood.
Such material is ordinarily treated with boiled oil or paint or with both.
According to our invention we coat or treat the woven material with solutious or
preparations of caoutchouc gutta percha balata or similar gum or substance or
with compounds or mixtures of such substances or containing large proportions of
such substances. In some cases the material is subjected to treatment to vulcanise
the applications.
The preparation may be applied to the belting by ordinary or suitable means
as for example by means of spreading rollers or doctors but we prefer to adopt
means for forcing the preparation to penetrate well into the substance of the
belting. To this end we may employ loaded rollers to force the preparation into
the belting or we may employ atmospheric pressure by withdrawing and
re-admitting air from and to a chamber containing the goods and preparation or
by passing the goods, from a vacuum chamber into the preparation or we may.
employ fluid pressure to force the preparation into the belting. We may place
the goods in a closed chamber and pump or force in the preparation or employ
fluid pressure within such chamber to force the preparation to penetrate into or
through the substance of the belting.
After such treatinent a surface coating may be obtained by the use of spreading
or coating rollers or doctors or by suitable means.

.COMPLETE SPECIFICATION.
Improvements in the Manufacture of Woven Belting.
We GEORGE BANHAM & COMPANY LIMITED of Pendleton Mill, Croft
Street, Pendleton, in the County of Lancaster, Woven Hose and Belting
Manufacturers, and CHARLES KAY SAGAR of the same place, Secretary to the
abore Company, 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, that is to say :—
Our improvements relate to the belting or driving bands composed of textile
material woven in such a manner as to produce a material of a thickness suitable
to the intended use of the belting as is well understood.
Such material is ordinarily treated with boiled oil or paint or with both.
According to our invention we coat or treat the woven material with solutions
or preparations of caoutchouc, gutta percha, balata or similar gum or substance or
with compounds or mixtures of such substances or containing large proportions of
such substances.
In
some cases the material is subjected to treatment to vulcanise the
applications.

page_text: The preparation may be applied to the belting by ordinary or suitable means
as for example by means of spreading rollers or doctors but we prefer to adopt
means for forcing the preparation to penetrate well into the substance of the
belting.
To this end we may employ loaded rollers to force the preparation into the
belting or we may employ atmospheric pressure by withdrawing and re-admitting
air from and to a chamber containing the goods and preparation or by passing the
goods from a vacuum chamber into the preparation or we may employ fluid
pressure to force the preparation into the belting.
For the purposes of our invention we may use any suitably strong chamber to
receive the goods. A cylindrical vessel made of wrought iron or steel or a strong
cast iron kier or chamber may be used. The chamber would be formed with a
man-hole provided with a lid or door adapted to be secured so as to be air tight.
The chamber would be connected with an air pump of an ordinary or suitable
construction and with a tank or cistern containing the preparation of gums, and
by preference with a pump for forcing in the preparation. The belting would be
introduced into the chamber which would then be closed and the air would be
withdrawn or pumped out. On the obtainment of a suitable
preparation would be admitted into the chamber. A pressure in excess of the
atmospheric pressure would then be produced in the chamber. This would be
obtained by pumping in the preparation until the desired pressure would be
obtained or by pumping in air or by admitting air steam or other suitable fluid at
a high pressure the intention being to drive the preparation into the interstices of
the belting. The preparation may be of an ordinary nature so long as it is made
from the gums or materials named or contains a suitable proportion of such gums
dissolved in suitable fluid solvents.
vacuum the
In a modification of the procedure we propose to employ a cylindrical container
open at the top and mounted upon the follower of a hydraulic press. A piston or
plunger to fit the interior of the container would be secured to the press head..
The belting and the preparation would be placed in the container and the press'
would be pumped up until the piston would be forced into the container so as
to produce a high pressure therein and thereby to drive the preparation into the
body of the belting.
It is obvious that the container might be stationary and the piston be forced
down into the container.
After removal from the chamber or container the belting may be passed
between rollers to smooth the surface and during this operation a thicker or more
viscid preparation of the gums may be applied so as to produce a surface coating.
As hereinbefore mentioned the belting may receive this surface coating rolled
in or otherwise applied without having been previously treated in a chamber or
container in the manner herein set forth.
.
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.
1. The treatment of the said woven belting with preparations of the indicated
nature forced into the body of the belting substantially in the manner and by the
means set forth.
2. The treatment of the said woven belting with preparations of the indicated
nature applied upon the surface of the belting and rolled in or forced into the
surface by means of doctors or of ordinary machinery used for similar purposes.
3. Belting of the indicated character having a coating of or permeated with a
preparation of the nature set forth applied substantially in the manner set forth.
