Improvements in Driving Belts.
A communication by LUDWIG LANDESMANN, of Aussig on the Elbe, Bohemia, in the
Empire of Austria, Banker..
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool and 6 Bank Street, Manchester both in
the County of Lancaster, 118, New Street, Birmingham in the County of Warwick
and 322, High Holborn in the County of Middlesex, Civil Engineer, 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 for its object a peculiarly (as double fabric) woven driving belt
with a woven-in leather border or edging, intended to be employed in many cases
where the ordinary leather driving belts are employed. This improved driving belt
has the advantage over the ordinary cotton driving belts hitherto used of considerably
greater durability.
A great fault in cotton driving belt is that the borders (edges) of the same (more
particularly in running through forks or when the belts are crossed) are very quickly
worn out or frayed and the whole fabric thereby loosened and soon destroyed.
According to the present invention, by weaving in the edges of the belt a narrow leather
belt or strip as warp there is produced a selvedge rib exhibiting a leather edge which
does not fray and is equally as durable and wear-resisting as the edge of a leather
belt.
This improved belt is woven after the manner of double fabrics with double warp
and double weft, the warps of the upper and lower layer consist of cotton threads of
suitable strength with the exception that at the edges on both sides some leather strips
are beamed which are intended to form the selvedge. The threads of the upper warp
are partly alone fastened above, and partly pass alternately from the upper into the
lower fabric and vice versa, and they therefore form so-called stitching threads which
effect a firm connection of both layers of fabric, namely, the upper and the under.
The weft consists of soft material such as binding thread, ordinary cotton yarn
and the like, and it binds alternately in the upper and under part of the belt and is
in fact a weft similar to linen binding or twill binding.
In the accompanying drawing,
Figures 1 to 3 are vertical sections (parallel to the warp) of the weft threads;
Figure 4 is a plan view of the belt with, for clearness sake, warp and weft threads
arranged together and indicated in all the figures by o for the upper warp threads
(only binding above) by u the under threads (only binding below) n the stitching
warp, the leather strips on the edges and s the weft.
As regards the belt loom it may be mentioned that it is preferable to beam the
various kinds of warp n o and u separately and more particularly to keep separate also
the leather edgings for the selvedge. By this means the thread tension is indepen-
dent of the various threads used.

page_text: Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
A driving belt woven as a double fabric and having its edges composed of leather
strips or straps which form selvedges substantially as described.
