Manufacturer for an Invention of "IMPROVEMENTS IN TENSION OR FRICTION
WINDING ON MOTIONS APPLICABLE TO TAPEING SLASHING OR PAPER AND
OTHER MACHINERY."

YATES DUXBURY Junior of Over Darwen Lancashire, Manufacturer
MENTS IN TENSION OR FRICTION WINDING ON MOTIONS APPLICABLE TO
SLASHING OR PAPER AND OTHER MACHINERY' "
" IMPROVE-
TAPEING,'
The improvements relate to what are known as winding on motions for 'tapeing,'
'slashing, paper and other analogous machinery, and are of a tensional or frictional
character.
In "winding on " motions as hitherto for the most part employed, the beam or
roller on which it is intended to wind the yarn, paper fibre or other analogous
material is suitably attached to a revolving apparatus carrying a friction plate.
The driving pulley is also suitably attached to apparatus, carrying another such
friction plate revolving parallel to the former one. These plates have their
opposing faces suitably prepared with flannel or other substance so that when
brought together by means of a scrow boss and intermediate spring, they form the
frictional winding on apparatus as is well understood.
To carry into effect this my present Invention, I employ an apparatus in lieu of
the screw and spring, for the purpose of applying the requisite tensional driving
aforesaid. This I obtain by affixing on a suitable fulcrum a lever by preference
forked so as to span the driving shaft.-On each of the legs of the fork I place an
antifriction bowl or pulley, which is capable of pressing on to the sliding friction
plate for the purpose of bringing it into contact with the other friction plate-I
then attach this lever by a suitable link to another lever mounted so as to have
Posion G
"

page_text: one arm thereof placed in about the horizontal position, and on which said arm a
weight may be slided, somewhat after the manner of a steel yard or weighting
motion.
By this means a fixed and known amount of tension may be applied to the
fabric or yarn which is being wound on to the beam or roller herein before
'described.
Variations in detail may be made without departing from the Invention, which
mainly consists in a peculiar application of levers acted upon by a movable
weight for the purpose of bringing the friction plates of winding on motions into
contact under a tension of pressure regulated by means of the weight aforesaid and
its position on the lever arm.

YATES DUXBURY, Junior, of Over Darwen, Lancashire, Manufacturer "IMPROVE-
MENTS IN TENSION OR FRICTION WINDING ON MOTIONS, APPLICABLE TO TAPEING,
SLASHING, OR PAPER AND OTHER MACHINERY."
The improvements relate to what are known as "Winding on
» motions, for
tapeing, slashing, paper and other analogous machinery, and are of a tensional or
frictional character.
In "winding on " motions, as hitherto for the most part employed, the beam or
roller, on which it is intended to wind the yarn, paper fibro, or other analogous
material, is suitably attached to a revolving apparatus carrying a friction plate or
plates. The driving pulley is also attached to apparatus carrying another such
friction plate or plates, revolving parallel to the former one. These plates have
their opposing faces suitably prepared with flannel or other substance, so that when
brought together by means of a screw-boss, and intermediate spring, they form the
frictional winding on apparatus, as is well understood.
To carry into effect this my present Invention, I employ an apparatus in lieu of
the screw and spring, for the purposo of applying the requisite tensional driving
aforesaid. This I obtain by affixing on a suitable fulcrum, a lever, by preference
forked, so as to span the driving shaft. On each of the legs of the fork, I place an
antifriction bowl or pulley, which is capable of pressing on to the sliding friction
plate, for the purpose of bringing it into contact with the other friction plate. I
then attach this lever, by a suitable link, to another lever, mounted so as to have
one arm thereof placed in about the horizontal position, and on which said arm a
weight may be slided somewhat after the manner of a steel yard, or weighting
motion. By this means a fixed and known amount of tension may be applied to
the fabric or yarn which is being wound onto the beam or roller hereinbefore
described.
But that the improvements may be better understood, I will by the aid of the
accompanying Drawings, proceed more fully to describe means employed by me.
DESCRIPTION OF DRAWINGS.
Fig. 1, is a front view of apparatus arranged according to my Invention; and
Fig. 2 is a side view thereof.
The same letters indicate corresponding parts wherever they occur.
a. a. are the sliding friction plates, and 6. b, are the second and similar friction
plates revolving parallel to a. a., and suitably connected with the driving wheel,
of which they may form the flanges. c. c. are the two anti-friction bowls or pulleys,
placed on the legs of the forked lever d. d, to which is connected a second lever e. e,
one arm of which is placed about the horizontal position, and carries a weight f. f.
capable of being slided along such arm, after the manner of a steel yard.
This weight when in use, presses forward the lever e. c, which in its turn moves the
forked lever dd, and so presses the bowls c. c. against one of the sliding friction
plates, thereby causing the friction plates to approach and come in contact with
each other, or it may be, only one pair of friction plates may be used, by which
means, the necessary frictional " winding on" motion is effected.
Having now described my improvements, and means I adopt in carrying the same
into effect, I would have it understood that I do not confine myself to the precise

page_text: details shewn and described, as variations may be made without departing from
the peculiar character of my Invention. But what I do claim is:
"
The application of levers acted upon by a moveable weight, for the purpose of
bringing the friction plates of "winding on inotions together, under a tension or
pressure regulated by the weight aforesaid, for the purpose and in manner
substantially as shewn and described.
In Witness whereof, I, the said Yates Duxbury, Junior, have hereunto set my
hand and seal this Twenty-sixth day of January in the year of our Lord,
one thousand eight hundred and eighty-three.
