Improvements in Belting for Machinery and the like.
I, JAMES FREEMAN BROWN, of the Town of Needham, in the County of
Norfolk, State of Massachusetts, United States of America, Gentleman, 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:-
The object of this invention is to attain a beit or belting, of great strength,
durability, and of but very slight stretch, if any and cheap in its manufacture,
which I attain in the following manner.
In the accompanying drawings
Figure 1., is a plan view of my invention:
Figure 2., is an edge view of Figure 1. :
Figures 3., and 4 are transverse sections illustrating that the materials (B)
and (C) may be folded.
Figures 5., 6., 7., and 8., are modifications in the design of the material (C) for
the purpose as hereinafter specified.
(A) represents my belting, (B) denotes one of the textile fabrics, and (C) the
other textile fabric or material, the essence of my invention.
The former is in nature as follows: (b) represents warp threads or longitudinal
cords, and (6) woof threads or transverse cords. In this material or fabric the
association of these woof threads with the warp threads is simply for the purpose
of keeping the warp threads or longitudinal cords in their relative position.
And the use of these woof threads is as few as possible so as to attain as much
as possible a straightness of the longitudinal cords without curves or crimps caused
by the association of the transverse cords with the longitudinal cords in the ordinary
manner of weaving.
The latter fabric is in nature as follows: (c) represents woof threads or

transverse cords, and (c 1) warp threads or longitudinal cords.
fabric, the association of these warp threads or longitudinal cords with the woof
threads or transverse cords is simply for the purpose of keeping the woof threads
or transverse cords in their relative position, for should there be a number of these
warp threads greater than the number used for the purpose just mentioned, they
would have no function to perform in a longitudinal direction owing to the greater
number of curves or crimps in excess to those to which the longitudinal cords of
the material (B) are subjected to, for the cords comprising the material (B) being
straight with the exception of a very few curves or crimps caused by the woof
threads, the cords will resist a stretch in a longitudinal direction, while the
longitudinal cords used in the fabric or material (C) would permit a stretch of the
belt in a longitudinal direction owing to the great number of curves or crimps,
which, when a longitudinal strain is applied, would tend to become straight, thus
subject the belt to a longitudinal stretch, which the material (B) is designed to
prevent.
Figures 5., 6., 7., and 8., illustrate that the material (C) may be made as
follows:
With the woof threads only at the ends for a sufficient distance, or with woof
threads portions and spaces alternatively, or a piece of the material applied at the
ends of the material (B), or the material (C) may be any ordinary material suitable
for helt making

page_text: The material (C) is solely for the purpose to prevent a longitudinal tear or
ripping of the belting, caused by connecting the two ends of the belt, by means
commonly employed for such purpose, and a strain in excess to the strength of the
belting when not having these woof threads or transverse cords.
I place these two materials together and treat with rubber or any other suitable
substance, compound, or material represented by (D), or stitched together and
folded, as to effect a belting.
Figures 3., and 4., illustrate that by folding these materials, any desired strength
can be attained according to the number of folds employed.
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 :
1st. A belt or belting made of two materials or textile fabrics, one consisting of
warp threads or longitudinal cords having associated therewith woof threads or
transverse cords as few as possible, simply for the purpose of keeping the warp
threads or longitudinal cords in their relative position, and the other material or
textile fabric consisting of woof threads or transverse cords, having associated
therewith warp threads or longitudinal cords as few as possible, simply for the
purpose of keeping the woof threads or transverse cords in their relative position ;
associated together and treated with rubber or any other suitable substance,
compound, or material, and stitched together and folded, substantially as and for
the purpose described.
2nd. In a belt or belting, a material or textile fabric consisting of warp threads
or longitudinal cords having associated therewith, woof threads or transverse
cords as few as possible, simply for the purpose of keeping the warp threads or
longitudinal cords in their relative position, in combination with a material or
textile fabric consisting in its length of woof thread portions and blank spaces
alternatively, the woof threads having associated therewith warp threads or
longitudinal cords as few as possible simply for the purpose of keeping the woof
threads or cords in their relative position, as described.
3rd. In a belt or belting a material or textile fabric consisting of warp threads
or longitudinal cords having associated therewith, woof threads or transverse
cords as few as possible simply for the purpose of keeping the warp threads or
longitudinal cords in their relative position, in combination with a material or
textile fabric consisting of woof threads or transverse cords having associated
therewith warp threads or longitudinal cords as few as possible simply for the
purpose of keeping the woof threads in their relative position, being for a sufficient
length applied to the respective ends of the first mentioned material, as described.
4th. In a belt or belting a material or textile fabric consisting of warp threads
or longitudinal cords having associated therewith, woof threads or transverse cords
as few as possible simply for the purpose of keeping the warp threads or cords in
their relative position, in combination with a material or fabric as is in common
use and suitable for belt making, substantially as described.
