PROVISIONAL SPECIFICATION.
An Improvement in Belts or Bands for Driving Machinery.
JOSEPH LEVER Engineer Bagot House Kersley near Manchester in the
County of Lancaster. I JOSEPH LEVER do hereby declare the nature of this
invention to be as follows:-
My invention consists of an improvement in (solid woven hair, cotton), canvas, or
other textile driving belts or bands-effected in the following manner.
A strip of thin supple hide, or leather, preferably that known as helvetia, is
secured to the face of the woven belt-in such a way as to allow the hide (which is
wider than the woven part) to fold over the edges on to the back of the woven or
textile belt-and firmly secured to it by, wax-thread, thong, or copper wire sewing.
By this means the edges are prevented from chafing or fraying by the action of
guide forks.
Thus the woven belt is enveloped partly or wholly by the helvetia hide, and
enables me to combine the tensile strength of a textile belt, to the efficiency of a
leather belt for griping the pulleys and withstanding the wear and tear of guide
forks.

COMPLETE SPECIFICATION.
An Improvement in Belts or Bands for Driving Machinery.
I, JOSEPH LEVER of Bagot House Kersley in the County of Lancaster
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 relates to means employed to prevent the chafing or fraying of
the edges of woven or textile driving belts (other than composition belts solutioned
together by gutta percha or indiarubber).
In proceeding according to these improvements I combine with the woven textile
belt a preparation of supple hide known as helvetia or raw hide-which is a
preparation of ox hide fulled or cured to retain as near as possible the strength and
thickness of the original ox hide.
The method of combining these two materials is as follows To the textile belt
I attach the helvetia or raw hide by means of cement wax thread thong or copper
wire sewing or rivets in the manner shewn in the drawing Fig. 1. The textile belt
is covered with the helvetia or raw hide in such a manner as to allow the hide to
fold round the edges on to the back of the belt thus covering entirely the face of
the textile belt which otherwise would be subject to surface friction on the pulleys
and also covering the edges and a small portion of the back of the belt which
would be exposed otherwise to the friction of guide forks. Also in cases where
belts are worked on both sides as in positions where gallows pulleys are used or
jockey pulleys are run on the back of the belt. The textile belt is then entirely
enveloped in helvetia or raw-hide as shown in drawing Fig. 2.
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. The combination of helvetia or raw hide in conjunction with solid woven hair

page_text: cotton, canvas, or other purely textile driving belts as in the aforesaid manner by
covering the face and folding the hide over the edges of the textile belt.
2. Solid woven hair, cotton; canvas, or other purely textile belts entirely cased
or enveloped in helvetia or raw hide to allow for jockey or other pulleys running on
both sides of the driving belts or bands.
Dated this Fourth day of September 1893.
