PROVISIONAL SPECIFICATION.
Improvements in or connected with Woven Driving Belting.
We, F. REDDAWAY & CO. LAMITED, of Cheltenham Street, Pendleton, Manchester,
in the County of Lancaster, Manufacturers of Woven Machine Belting and Hose,
and GAYLARD MACK, Weaving Manager, with the said firm, do hereby declare
the nature of this invention to be as follows:-
Our said invention relates to improvements in or connected with woven driving
belting, and has reference to means whereby the belting is rendered more durable.
Such woven driving belting is very liable to crack upon the face due to the
frictional contact with the pullies and this cracking seriously affects the life of the
belting.
The object of our invention is to overcome this defect.
In carrying our invention into effect we weave the face of the belting intended
to come in frictional contact with the pullies in such a way that the warp threads
"twill
only appear on the surface. To effect this the face is woven
"
or satin"
or other suitable pattern which will cover or bury the weft threads. The face of
the belting is thus rendered so much smoother and free from projecting weft threads
that the risk of cracking is greatly reduced and the life of the belt corres-
pondingly increased. If desired both faces of the belt may be so woven.
Our invention may also be applied to stitched or solutioned belting composed
of a number of plies of material stitched or cemented together, one or both of such
outside layers being woven twill" or "satin" or other suitable pattern to bury
or cover the weft threads.
Improvements in or connected with Woven Driving Belting.
We, F. REDDAWAY & CO. LIMITED, of Cheltenham Street, Pendleton, Manchester,
in the County of Lancaster, Manufacturers of Woven Machine Belting and Hose,
and GAYLARD MACK, Weaving Manager, with the said firm, 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 said invention relates to improvements in woven driving belting and has
reference to means whereby the belting is rendered more durable.

page_text: The woven driving belting to which our invention relates is woven throughout
its thickness with a plain weave so as to obtain a belt with little elasticity and
therefore not so liable to stretch.
A serious disadvantage however is attended with such plain woven belting, the
plain weave leaving the surface of the belting in a rough state, due to the project-
ing weft threads.
As a consequence the belting is very liable to crack upon the
face due to frictional contact with the pullies, the constant friction frequently
wearing through the projecting corrugations of the surface.
Further, such wearing and cracking is accelerated by the shrinking of the contact
face of the belting in case the same by any means absorbs moisture. This cracking
as described, seriously affects the life of the belting.
"
".
The object of our invention is to overcome this defect and this we do by weaving
the face of the belting intended to come into frictional contact with the pullies,
in such a way that the warp threads only appear on the surface.
To effect this the face of the belting is woven
twill" or satin in such a
manner as will produce a smooth and elastic face upon a solid plain weave belt
retaining all the advantages of the plain weave. It will be understood that the
face only is so woven the remaining thickness of the belt being woven in the usual
plain weave.
The face of the belting is thus rendered so much smoother and free from
the corrugations of the weft threads so that the frictional wear upon the contact
face of the belt is greatly reduced and the risk of cracking obviated.
The life of the belting is thereby greatly increased.
The compound woven belt with contact face, moreover, has the further
advantage that owing to the greater elasticity imparted by this method of weaving
all damage from shrinkage is obviated, whilst this elasticity being merely superficial
does not affect the body of the belting.
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) Weaving the face of driving belting "twill" or satin so as to cover or
bury the weft threads in conjunction with the body of the belt woven plain for
the purpose and substantially as described.
2) The improved woven driving belting consisting of a plain woven belt with a
twill" or satin face substantially as described.
