Improvements in Belts or Bands for Driving Machinery.
I MAURICE GANDY of 5 Ansdell Street Liverpool in the County of Lancaster, Belt
Manufacturer do hereby declare the nature of my invention for "IMPROVEMENTS
IN BELTS OR BANDS FOR DRIVING MACHINERY" to be as follows:-
I take cloth and fold it into narrow belts and then place these on each other until
I have built up the belts into the shape desired and then unite them by stitching
cementing or rivetting. I thus produce a belt to work in grooved pulleys and which
has all its sides suitable for contact with the pulley.
Or I weave narrow belts of any thickness desired and by these build up the belt to
the desired shape and then unite by stitching riveting or cementing or I use part cloth
and part solid woven belt for the purpose and unite the same way.
Or I arrange the warps in the loom and weave this square or angular belt. to the
shape desired without stitching and thus produce the textile belt to work on all its
sides if need be, in grooved pulleys. I thus produce a belt to take the place of ropes
in transmitting power on pulleys that are grooved and this square or angular belt is
of great utility.

page_text: I, MAURICE GANDY of 5, Ansdell Street, Liverpool, in the County of Lancaster, Belt
Manufacturer 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 :-
In the accompanying Drawings Figures 1. 2. 3. 4. 5. 6 and 9 illustrate square belts
formed in various ways. Figure 7 illustrates a triangular belt and Figure 8 a square
belt at work driving two pulleys.
My Invention relates to that class of machine belts which are made to run in
V shaped grooved pulleys and of which more than one flat side is used for friction
contact with the driving surfaces of the groove of the pulley, and my invention consists
of forming such belts of textile material, combined and united substantially as herein
designated in the claims concluding this specification.
Various forms of the above-described belts may be made, the form employed
depending upon the requirements of the work to which they are put, and upon the
form of the pulley and grooves in which they are to run. They may be formed of
cotton, wool or other fibre and made square and run edgewise in a grooved pulley
(see fig. 8), or round, or elliptical, or angular, or any other form having three or more
driving surfaces to operate on a grooved pulley. Ordinary machine belts, as is well
understood, have but two driving surfaces.
The above described textile belts may be made in various ways. They may be made
by weaving in a loom similar to that used for weaving the ordinary flat, solid woven
belting by using a greater number of warps and a greater number of heedles, so that
a sufficient number of sheds shall be cast up and down to obtain the required thickness
to form a square or angular belt (see figs. 1 and 2). In this case the belt will be
formed in one operation of weaving. They may then be stitched, if desired,
horizonally and vertically, or either, to compact and strengthen them, as in fig. 1, or
left unstitched, as in fig. 9.
I also form said square belts by taking several breadths of solid woven belting the width
the band is to be and piling them up, one on top of the other, until the thickness
requisite to make a square or nearly square belt is obtained. I then sew the layers
firmly together by stitching them through and through by rows of stitching, & or by
rivetting, or cementing. Such a belt is illustrated in fig. 2 of the annexed drawing.
I also form said square belts by weaving the canvas in wider widths and folding it
into the desired form, as illustrated in fig. 3, where the canvas is doubled or folded
again and again upon itself; or as illustrated in fig. 4, where separate widths of canvas
are separately folded so as to conceal the selvage edge within the belt and a sufficient
number of these folded flat belts piled one on top of the other to form the required
proportions. In either case the belt is stitched rivetted, or cemented to unite the
plies or folds together.

page_text: Instead of forming the belt in either of the above described ways I may and do form
it substantially as illustrated in fig. 6. That is to say, instead of making the belt so
that two sides of said belt are formed on the flat sides of the external lamina and two
of the edges of the lamina, all the sides may be formed of the edges of the lamina.
And this may be accomplished in the following manner: Several lamina may be piled
in the form of a triangle (a, b, c, d, e, and j, k, l, m, n, for instance) and stitched rivetted,
or cemented together. Between these two triangles placed base towards base several
other longer layers (such as f, g, h, i, i, ) completing the square are placed and united
to the lamina of said triangles and to each other by other rows of stitching rivetting,
or cementing s, as or substantially as illustrated.
The
One of the advantages of forming the belt in this manner is that the needles_in
stitching are not required to pass through the entire diagonal width of the belt.
unstitched portion in the centre is that part of the belt which is subjected to the least
strain in driving and increases the flexibility of the belt.
These belts may also be formed of a combination of solid woven bands u and folded
bands, or bands of single thickness without folding w stitched or unstitched, before
being united by stitching, rivetting, or cementing together in the form of the belt, as
illustrated in fig. 5.
Heretofore for the sake of simplicity I have confined the description of my improved
belt to forming square belts, but instead of being formed square they may be triangular
(see fig. 7) or of other desired form by the methods described.
Belts of the character above described may be employed to drive one pulley, or
more than one pulley. A square belt working between, and actuating two pulleys, p
and p', is illustrated in fig. 8 of the drawings.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is
(1) A new article of manufacture consisting of a belt or band for driving machinery
composed of woven fabric and having three or more driving surfaces to operate a
grooved pulley, substantially as described.
(2) A belt or band for driving machinery composed of a solid woven textile fabric,
having three or more driving surfaces, stitched through and through in one or more
directions.
(3) A belt or band for driving machinery composed of woven textile fabric having
three or more driving surfaces formed of separate widths of fabric piled in the desired
form and united by rows of stitching rivetting, or cementing substantially as
described.
(4) A belt or band for driving machinery composed of woven textile fabric having
three or more driving surfaces formed of canvas folded and. stitched rivetted, or
cemented substantially as described.
(5) A belt or band for driving machinery composed of textile fabric having three
or more driving surfaces composed of several widths of canvas separately folded as
described and united together by stitching rivetting, or cementing to form a belt,
substantially as described.
