PROVISIONAL SPECIFICATION..
An Improvement in the Manufacture of Driving Bands.
I JOHN WORTH of 12 Grandridge Street Rochdale in the County of Lancaster
Mill Furnisher do hereby declare the nature of this invention to be as follows:-
This invention relates to the manufacture of driving bands such as are employed
for driving spindles and for similar purposes and the object of the invention is to
increase the strength and durability of the bands.
In the manufacture of these driving bands, each strand is composed of a number
of-yarns or threads laid side by side, and a certain amount of left hand twist put
into them.
The required number (say) two, three, or more are then twisted together to the
right hand, making what is called a "cable laid cord."
According to my invention each strand instead of being made from so many
yarns or threads laid side by side, is made of a number of yarns or threads plaited
or braided together into a tubular form. These tubular braided strands, are then
twisted to the left hand, and the required number of them are then laid together
and twisted to the right hand, and it will be found, that driving bands made from
these tubular plaited or braided strands, will be much stronger and more durable
than those made from lightly twisted strands in the usual manner.
Dated this 18th day of September 1891.

COMPLETE SPECIFICATION.
An Improvement in the Manufacture of Driving Bands.
I JOHN WORTH of 12 Grandridge Street Rochdale in the County of Lancaster,
Mill Furnisher, 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 the manufacture of driving bands such as are employed
for driving spindles and for similar purposes, and the object of the invention is to
increase the strength and durability of the bands.
In the manufacture of these driving bands each strand is usually composed of a
number of yarns or threads laid side by side and a certain amount of left hand
twist put into them.
The required number (say) two, three, or more are then twisted together to the
right hand making what is called a "cable laid cord."
According to my invention each strand, instead of being made from so many
yarns or threads laid side by side is made of a number of yarns or threads
plaited or braided together into a tubular form. These tubular braided
strands are then twisted to the left hand, and the required number of them
are then laid together and twisted to the right hand, and it will be found that
driving bands made from these tubular plaited or braided strands will be much
stronger and more durable than those made from lightly twisted strands in the
usual manner.
In making strong driving bands for large spindles or shafts or other driving
purposes where greater strength is required, the above operations are repeated
until the desired thickness and strength have been obtained.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The improvement in the manufacture of driving bands consisting in the use of a
number of braided strands twisted together (instead of the lightly twisted straight
strands hitherto employed) whereby increased strength and durability are obtained
substantially as hereinbefore more particularly described and set forth.
Dated this 6th day of April 1892.
