PROVISIONAL SPECIFICATION.
Improvements in and relating to Driving Belts and Bands or Ropes:
I, ROBERT DICK of Greenhead, Glasgow, Lanarkshire, Manufacturer, do hereby
declare the nature of my said invention to be as follows:-
This Invention has for its object the production of driving belts, and bands or ropes,
of great tensile strength, and of greater yielding or elastic action and gripping power
on the pulleys than heretofore with such belts or bands.
My present improvements consist in forming composite driving belts, and bands or
ropes, from a union fabric woven from cotton and wool yarn, or linen and cotton, or
linen and wool yarn, and preferably having the wool as the weft; and these fabrics
would be coated in the web on one or on both sides with one or more coatings of a
solution of gutta percha, balata, or mixtures of either or both of these, and then
folded into the required breadth for the flat belts, and rolled into the diameter or
circumference for the round bands or ropes, and into the requisite number of plies
or thicknesses. For main or thick heavy flat driving belts of this description, it
would still be preferred to keep, one, two, three or more plies of the composite
canvas and gutta percha fabric, in the centre of the band, but to have the union
fabric of wool and cotton or linen folded to form one, two or more layers or plies
en the outside surfaces of the said composite canvas and gutta percha all com-
pressed together while in a heated state and manufactured otherwise substantially
as described in the Specifications of Letters Patent granted to me Nos. 12,253
and 12254 both dated 14th October 1885. Or instead of making these outer
layers of a union fabric as described, they might be made of a strong woollen
fabric similarly coated or saturated with the gutta percha solution on both sides
and cemented and attached to the inside gripping surface of the said composito
canvas band, or otherwise a layer of thin leather cut into lengths of the hide, and
the width of the band, might be solutionized and attached on the inside of the
band by gutta percha solution, spliced at the ends without sewing or lacing, all of
which would give the greater bending and yielding gripping surface on the pulleys
desired, especially suitable for passing round smaller diameter pulleys, than these
composite bands as heretofore made under my former improvements.

COMPLETE SPECIFICATION.
Improvements in and relating to Driving Belts and Bands or Ropes.
I, ROBERT DIOK, of Greenhead, Glasgow Lanarkshire, Manufacturer, do hereby
declare the nature of my invention and in what manner the same is to be per-
formed, to he particularly described and ascertained in and by the following
statement in writing, that is to say:
-
My Invention has for its object the production of driving belts, and bands or ropes,
of great tensile, strength, and of greater yielding or elastic action and gripping
power on the pulleys than heretofore with such belts or bands.
My present improvements consist in forming composite driving belts, and bands or
ropes, from a union fabric woven from cotton and wool yarn, or linen and wool yarn,
and preferably having the wool as the weft, or from cotton and linen with linen as
the weft; and these fabrics are coated in the web on one or on both sides with one or
more coatings of a solution of gutta-percha, balata, or mixtures of these, and then
folded into the required breadth for the flat belts, and rolled into the diameter or

page_text: circumference for the round bands or ropes, and into the requisite number of plies or
thicknesses. For main or thick heavy flat driving belts of this description, it would
still be preferred to keep, one, two, three or more plies of the composite cotton canvas
and gutta percha fabric, in the contre of the band, but to have the union fabric of
wool and cotton or linen folded to form one, two or more layers or plies on the
outside surfaces of the said composite canvas and gutta-percha all compressed together
while in a heated state, and manufactured otherwise, substantially as described in the
specification of Letters Patent granted to ne Nos. 12,253 and 12254 both dated
14th October 1885. Or instead of making these outer layers of a union fabric as
described, they may be made of a strong woollen fabric similarly coated or saturated
with the gutta-percha solution, on both sides and comented and attached to the inside
or gripping surface of the said composite canvas belt, or rolled and cemented on the
outside surface when applied to round driving bands or ropes; or otherwise a layer
of thin leather cut into lengths of the hide, and the width of the band, may be
solutionized and attached on the inside or gripping surface, or at the edges of the
belt by gutta-percha solution, spliced at the ends without the necessity of sewing.or
lacing, all of which would give the greater bending and yielding gripping surface on
the pulleys desired, especially suitable for passing round smaller diameter pulleys,
than these composite belts as heretofore made under my former improvements.
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 :-
First. The manufacture and use of driving belts, and bands or ropes, from a union
fabric woven from cotton and wool yarn, or linen and wool yarn, or cotton and linen
yarn, and coated in the web on one or on both sides with a solution of gutta-percha,
balata, or mixtures of these, and then formed into the belts or bands either with or
without layers of cotton canvas in the centro, substantially as herein described.
Second. The manufacture and use of driving bolts having an outer layer for
surface of gutta (percha solutionized canvas or union fabric, and an inside layer
or gripping surface of gutta-percha solutionized woollen fabric, or of leather, sub-
stantially as herein described.
Third. The manufacture and use of round driving bands or ropes made of
rolled layers of union fabric of wool and cotton yarn or wool and linen yarn, or
of woollen cloth solutionized with gutta percha or balata on both surfaces, sub-
stantially as described.
