in the County of York, Manufacturer, for the Invention of
"IMPROVEMENTS IN MACHINERY OR APPARATUS TO BE EMPLOYED IN THE

Sealed the 26th August 1873, and dated the 8th July 1873.
PROVISIONAL SPECIFICATION left by the said Leedham Binns at the
Office of the Commissioners of Patents, with his Petition, on the
8th July 1873.
I, LEEDHAM BINNS, of Oakenshaw, near Bradford, in the County of
York, Manufacturer, do hereby declare the nature of the said. Invention
for "IMPROVEMENTS IN MACHINERY OR APPARATUS TO BE EMPLOYED IN THE
MANUFACTURE OF ENDLESS BANDS, CORDS, OR ROPES," to be as follows:—
The Invention has for its object improvements upon a former
Invention for which Letters Patent were granted to me, dated
November 1st, 1872,. No. 3238, and consists in the application of
means whereby the drag or tension on the material employed in the
manufacture of endless bands, cords, or ropes, is regulated in proportion

page_text: to the amount of such material remaining on the bobbins, reels, or other
articles upon which such material is wound or placed, by which means
I am enabled to make any given number of such endless bands, cords,
or ropes of an exactly or approximately similar length, tension, and
character.
Heretofore in the manufacture of endless bands, cords, or ropes I have
found that they are made with varying tension, and therefore vary in
length and character, as the bobbins or reels are more or less nearly full
or empty, as there is less tension on the material when a bobbin or reel
is full than there is when a bobbin or reel is more or less exhausted.
One mode in which my Invention may be carried into effect is by
mounting some of the tension knobs, studs, or pins, around which the
material for forming the core passes on a moveable arm, rod, or bar,
mounted on an axis of motion, or otherwise mounted in such manner
as to be capable of separating from, and approaching to other fixed
tension knobs, studs, or pins. And I operate the arm, rod, or bar,
carrying such moveable tension knobs, studs, or pins, in such manner
as to cause them to gradually approach the fixed tension knobs, studs,
or pins, in proportion to the amount of material remaining on the
bobbins, reels, or other articles carrying it, thereby putting less and less
tension or drag on the material as it is being used off the bobbin, reel, or
other article carrying it.
Another mode in which the tension or drag on the material for
forming the core, and also on the covering material, may be varied or
regulated, is by causing springs or spring arms to rest on the material
on the bobbins, reels, or other articles carrying it, by which means the
pressure on the material, and consequent drag or tension thereto, will be
varied or regulated in proportion as such material is being used.
I would here remark that the mode of varying or regulating the
tension or drag on the material employed in the manufacture of endless
bands, cords, or ropes, for the purpose described, may be varied without
departing from the peculiar character of my Invention.
