A New or Improved Manufacture of Driving Belt.
I, JOHN WALKER FORREST of 53 Shewsbury Road, Birkenhead, in the
County of Chester 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:-
This invention has reference to belts for driving machinery, and consists of a
new or improved manufacture of leather belt, made, and having the characteristics,
as hereinafter described.
A leather belt according to this invention consists of interwoven strings of
leather, constituting continuous warps and weft of rectangular or rounded section
without join or splice; such continuous leather strings being made out of leather
hides by cutting them spirally, i.e. round and round, into continuous strings or
strips; and these strings, as warps and weft being woven in the manner described
and as illustrated in the accompanying drawing.
The drawing given shews the belt in plan or face view; and in it a designates
the warps, and 6 the wefts. In the belt shewn, the warps are carried down in
straight or parallel lines through the belt; and the manner of weaving consists in
passing each warp over two wefts, then under a single weft, and again over two
wefts, and so on repeatedly throughout the belt; the successive or adjacent warps
being passed in between the two wefts which are spanned by the wefts next it.
By this arrangement of pick or design, a surface (as shewn by the drawing) upon
the belt is produced which gives a good grip between it and the pulley over
which it is used. The warps and wefts are, preferably, about equal in width to the
thickness of the hide, say the average thickness of the hide; or they may be
slightly wider or narrower.
The pattern of the face of the belt shewn in the drawing is diagonal, but by
suitably adjusting the movement of the loom in the well known ways, it may be
made of a reverse diagonal kind, or of zig zag, or other desired kind.
If a thick belt is required, the warps are double, and in this case two warps
would be passed over the two wefts and then under a single one, as described,
instead of a single warp, as in the case described and shewn.
The weaving of the belt may be done in looms of any known suitable kind.
A belt made as described is relatively inexpensive, and at the same time strong,
as the weaker parts of the hides will not be concentrated at one part of the belt,
but will be distributed over it, and the weaker and stronger parts of the hides will
lie side by side in its width, and be distributed at different parts over its length.
Thus a belt is provided in which substantially the whole of leather hides are
practically rendered serviceable for belt making, and are used in it; the strength
or breaking strain of which, at any point along its length, is equal to or approximates
the average strength of the hides. To provide these characteristics, and effect
these ends, has been the object of the invention, and it is accomplished in the belt,
and by the mode of making it, described.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The manufacture of driving belt herein described, namely, a leather belt

page_text: made by cutting up leather hides into continuous or long strings or strips as
specified, and interweaving them as warps and weft: substantially as set forth for
the purposes specified.
2. The herein described driving belt, namely, a leather belt consisting of inter-
woven strings of leather in continuqus lengths without join, cut or formed as
described, and constituting warps and weft in the belt; substantially as and for
the purposes herein set forth.
3. The woven leather belt consisting of warps a and wefts b, consisting of leather
strings in one continuous length without join or splice, and woven up together
particularly in the manner set forth with reference to and shewn in the drawings.
