PROVISIONAL SPECIFICATION left by Frederick Hyde at the Office
of the Commissioners of Patents, with his Petition, on the 16th January,
1858.
I, FREDERICK HYDE, of Glossop, in the County of Derby, Mechanic, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR SPINNING, DOUBLING, TWISTING, OR THROWING
COTTON, SILK, WOOL, FLAX, AND
FLAX, AND OTHER FIBROUS SUBSTANCES," to be as
follows:-
thm, x!
I cause the thread or yarn to regulate its own drag, by which means, what-
ever be the diameter of the cop or bobbin the strain upon the yarn or thread
is always equal.
To effect this I have a flyer upon the spindle of a suitable. construction,
that is, that it can be taken off and put on at pleasure, being therefore
independent of the spindle. This flyer is driven by a motion produced by the
friction of a wharve against a disc or face plate of leather or other elastic
substance made to revolve at the required velocity. Upon the wings of the
flyer I put a washer of leather or other suitable substance, so made that the
cop or bobbin can pass through the inside diameter, and the outside diameter
exceeds the span of the flyer by a quarter of an inch (more or less, as
convenient). This washer I make to slide up and down the wings of the flyer

page_text: by means of the outer edge being introduced into a groove or slot fastened to
the lifter. I then attach an eye to the washer and bring the yarn or thread
from the cop or bobbin upon the spindle through this eye up to the delivery
rollers. A separate motion causes the spindle to revolve slower than the flyer,
which latter carries the washer round with it, so that the thread carried round
by the eye of the washer winds itself round the cop or bobbin upon the
spindle.
If the strain upon the yarn be greater than required it causes the friction of
the washer inside the groove or slot to retard the motion of the flyer, and so
instantly brings it to the drag intended. The retarding strain of the thread or
yarn can be adjusted at pleasure by varying the pressure against the sides of
the leather disc or face plate which drives the flyer. The disc or face plate
must be unsupported at the outer edges, and so arranged as to be able to give
way to pressure, so that when pressed and driven away from the line of
revolution the centrifugal force exerts itself to restore it to the line of
revolution upon the axis of the shaft upon which it revolves, thereby causing
it to press in ratio to the distance it is pushed and the velocity with which it
revolves; or, instead of the leather disc and friction wharve, I put upon the
flyer a fan-like wharve which I drive at the required velocity by means of a
current of air compressed into pipes behind the spindles and blown against the
said wharve.
By the use of my improved apparatus for spinning, &c., I am enabled to
form cops upon the bare spindle, and also to twist the thread or yarn at the
same time that it is being wound upon the cop or bobbins.
The motion which I apply to the lifter is produced by an endless chain
carrying studs moving with an uniform motion over a surface which can be
varied according to any of the usual methods at present in operation for that
purpose.
