Improvements in and connected with Woven Driving Belts.
I, JAMES CHARLES FISHER of 20 Rook Street Manchester in the County of
Lancaster, Cotton Spinner, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in woven driving belts, the objects of
the improvements being to produce greater flexibility, to prevent the separation of
the plies through the breaking of the binding threads, and to produce a finer and
more even face on each side of the belts. A further object is to ensure greater
durability and better adhesion to the pulleys.
In weaving a belt to embody these improvements 1 make an entire re-arrangement
of the binding warp threads, and I may also re-arrange the ordinary warp threads.
The binding threads are arranged one, two, or three, in a dent, and are woven
into the belt in such a manner that they bind in every pick of weft successively
from one face of the belt to the other, and then return and repeat. Thus, in
a four ply belt, reckoning the weft threads from the top, the binders may pass
over 1, under 3, over 2, and under 4, and repeat. In larger numbers of plies, an
equivalent arrangement may be used.
The belt may be woven with ten or more shafts, the first two of which may
carry the binding threads, the next pair the face threads,, and the last pair the
back threads, the intermediate or filling threads being carried by the intermediate
shafts.
The warp threads are preferred to be cabled, or in other words, to consist of
several threads or ends twisted together.
The belt is improved by being treated, after it has been woven, with a suitable
mixture or compound having water proofing, softening, and preservative characters.
Such a mixture may contain almadina, tallow, and vegetable tars and pitches,
the belt being immersed in the melted mixture, after which it may be run between
rollers to express the superfluous compound.

1, JAMES CHARLES FISHER, of 20 Rook Street, Manchester, in the County of
Lancaster, Cotton Spinner, 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 woven driving belts, the objects of
the improvements being to produce greater flexibility, to prevent the separation of

page_text: the plies through the breaking of the binding threads, and to produce a finer and
more even face on each side of the belts. A further object is to ensure greater
durability and better adhesion to the pulleys.
In weaving a belt to embody these improvements I make an entire re-arrange-
ment of the binding warp threads, and I may also re-arrange the ordinary warp
threads.
The binding threads are arranged one, two or three in a dent, and are woven
into the belt in such a manner that they bind in every pick of weft successively
from one face of the belt to the other, and then return and repeat.
Thus, in a four ply belt, the arrangement of the binding threads may be that
illustrated by the accompanying diagram to which I will now refer.
A indicates one of the binding threads, B the ordinary warp threads, and 1, 2, 3,
and 4 the weft threads. In the arrangement illustrated the binder passes over
weft No. 1, under weft 3, over weft 2, and under weft 4 and repeats.
An equivalent arrangement would be used for a larger number of plies.
The belt may be woven with ten or more shafts, the first two of which may
carry the binding threads, the next pair the face threads, and the last pair the
back threads, the intermediate or filling threads being carried by the intermediate
shafts.
The warp threads are preferred to be cabled.
The belt is improved by being treated after it has been woven, with a suitable
mixture or compound having waterproofing, softening and preservative characters.
Such a mixture may contain almadina, tallow, any suitable oil such as olive or
cotton seed oil, and a pitch such as that which is obtained from the residue resulting
from the purification of crude cotton-seed oil by caustic soda. This pitch is
described in Thorpe's "Dictionary of Applied Chemistry" volume III., pages 250
and 251. A convenient mixture for general use consists of one part of oil and
tallow mixed, and three parts of pitch. The mixture is melted and the belt is
immersed in it, after which it may be run between rollers to consolidate it and to
express any superfluous compound.
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 :-
As a new article of manufacture, a woven driving belt treated or impregnated
with a suitable mixture and having its binding warps arranged substantially as
hereinbefore described and as illustrated by the accompanying drawings.
