page_text: I SAMUEL OGDEN of West Mosley Street Manchester in the County of Lancaster,
Merchant do hereby declare the nature of this invention to be as follows:-
This invention relates to woven driving bands or belts and has for its object to
diminish or prevent ravelling or fraying of the edges of the belt while in use and
the consequent rapid destruction of the belts.
These improvements consist in the application of certain substances or materials
to the edges or selvedges of the bands or belts for the purpose of reducing the
friction between the edges of the bands or belts and the strap forks, guides or
other similar apparatus.
The substances which may be employed for the purpose of this Invention are
shellac ozokerit or earth wax paraffin wax vegetable or beeswax and analogous
substances which may be used alone or in combination with each other. To any
of these substances or to a mixture of them there may be added powdered talc,
powdered plumbago, resin or similar substances.
Any of the foregoing articles or analogous substances or a compound thereof may
be applied to the selvedge warp threads before weaving by passing them through
the molten substance or compound or it may be applied during weaving by
brushing or similarly applying the melted substance or compound upon the
selvedge and after weaving by immersing the edges of the band or belt in the
melted substance or compound or by brushing it upon the edges or otherwise
suitably applying it.
Bands or belts treated as hereinbefore indicated acquire after a short period of
use a smooth hard edge which is not liable to ravel or fray in ordinary wear and
thus prevents the destruction of belts subjected to guide friction.

page_text: I, SAMUEL OGDEN, of West Moseley Street Manchester in the County of Lancaster
Merchant 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 relates to textile or woven driving bands or belts and has for its
object to diminish or prevent injurious wear and tear arising from the ravelling or
fraying of the edges or selvedges of such bands or belts while in use and con-
sequently to prevent or retard their early deterioration and destruction especially
when they are frequently shifted by a strap fork or other means or have to work
with their edges in constant or occasional contact with fixed or relatively fixed
objects.
These Improvements consist in the-application to or incorporation with the edges
or selvedges or to or with the material forming the edges or selvedges of such belts
or bands, of certain materials or compounds which are capable when so applied or
incorporated of forming or producing a comparatively frictionless surface and which
will also to some extent act as agglutinants. Among such substances are shellac,
resin, tallow, ozokerit or earth wax, paraffin wax, carnuba or vegetable wax, bees
wax, pitch and analogous substances alone or in a combination of two or more of
them. To such substances or compounds there may be added powdered mica, talc,
steatite, plumbago and similar substances.
The hereinbefore mentioned substance material or compound may be applied to
or be combined or incorporated with the edges or selvedges of the bands or belts
either during or after their manufacture by any suitable means. Thus, the selvedge
warp threads may before or during weaving be coated or impregnated with the
substance or compound, which may be effected for example by passing the selvedge
threads through the substance or compound while it is in a warın melted or liquified
condition. After the bands or belts have been woven or manufactured the edges
or selvedges may be painted charged coated or impregnated with the warm melted
or liquified substance or compound.
Driving bands or belts treated as hereinbefore described acquire after a short
period of use a smooth hard edge and are thereby rendered much less liable to
ravel or fray at the edges especially when subject to great friction or wear.
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) In the manufacture or preparation of textile or woven driving bands or belts,
coating charging and impregnating the material at the edges or selvedges thereof

page_text: with the hereinbefore described and analogous materials and compounds, being
such as are capable of resisting ravelling or fraying of the material, and the
improved article of manufacture thus produced.
(2) Coating charging and impregnating the edges and selvedges of textile or
woven driving bands and belts with the materials and compounds hereinbefore set
forth, substantially as and for the purpose described.
