This invention consists of improved apparatus which automatically adjusts the
pressure upon, and consequent action of the "friction plates" employed in con-
nection with the sized yarn beam.
According to this my invention in the construction of apparatus for purpose
aforesaid I employ a long collar, or boss, on which is cut or chased a coarse pitched
thread, or worm which passes and works through a supporting lug attached to the
end frame of the machine. The inner end of the screwed long collar terminates
by a flange which comes in contact with the boss of the outer friction plate.
On the screwed long collar and at a point between the flange of the said collar,
and the supporting lug is a nut with an internal thread same pitch as collar from
which extends a cranked lever or handle on the end of which is a ball or weight
the leverage tends to turn the nut, and thus force the flange thereof against the
boss of the friction plate whereby the friction is applied.
A key bed is cut along the screwed part of the long collar and a holding pin
passed through its supporting bracket so that the said collar cannot turn round.
There is a finger plate extending from the screwed nut on the long collar, in
which finger plate set screws are secured the set screws also pass through the arm
of the weight lever and in which is a quadrant, or radius slot so that the position
or angle of the lever and weight can be regulated thereby to adjust the weighting,
and friction to the required degree. A stop, or rest piece is provided and which
prevents any overweighting of the beam.
I also employ between the friction plates a coiled or blade spring to ensure the
plates seperating as soon as the weighting pressure is taken off.

Improvements in or Connected with the Friction Plates of Yarn
Sizing Machines.
"
I, PETER BRIMELOW of 54 Shepherd Street, Bury, in the County of Lancaster,
Mechanic do hereby declare the nature of my invention for "IMPROVEMENTS IN
and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
OR CONNECTED WITH THE FRICTION PLATES OF YARN SIZING MACHINES
This invention consists of improved apparatus which automatically adjusts the
pressure upon and consequent action of the "friction plates" employed in con-
nection with the sized yarn beam.
According to this my invention in the construction of apparatus for purpose
aforesaid I employ a long collar, or boss on which is cut or chased a coarse pitched
thread, or worm which passes and works through a supporting lug attached to the
end frame of the machine.
The inner end of the screwed long collar terminates by a flange which comes in
contact with the boss of the outer friction plate..
On the screwed long collar and at a point between the flange of the said collar and
the supporting lug is a nut with an internal thread same pitch as collar from which
extends cranked levers or handles, on the end of which is a ball or weight, the
leverage tends to turn the nut or force the flange thereof against the boss of the
friction plate whereby the friction is applied.
A key bed is cut along the screwed part of the long 'collar and a holding pin
passed through its supporting bracket so that the said collar cannot turn round.
There is a finger plate extending from the screwed nut on the long collar in
which finger plate set screws are secured, the set screws also pass through the arm
of the weight lever and in which is a quadrant or radius slot, so that the position
or angle of the lever and weight can be regulated thereby to adjust the weighting
and friction to the required degree.
A stop or rest piece or ratchet is provided and which prévents any overweighting
of the beam when friction is adjusted.
I also employ between the friction plates a coiled or blade spring to ensure the
plates separating as soon as the weighting pressure is taken off.
Such being the nature and object of my said Invention the following is a com-
plete description of same; reference being had to the accompanying Drawings
forming a part of this Specification in which
Fig. 1 is an end view of my improved 'apparatus.
Fig. 2 is front elevation of same.
A
"The several views on Sheet 2 are details drawn to enlarged scale.
At 1 is the long collar of boss on which is chased the thread 2 and along the
said collar or boss is cut the recess or slot 3 in which is the key 4 which pivots on
the end of the screw 5 passing through the supporting boss 6 attached to the end
frame 65.

page_text: At 7 is a collar nut, on the inner side of which is the thread or piece 8 which
serves as an internal thread and engages with the thread of the long collar or
boss 1.
At 9 is the hand lever fastened by screw 9ª on the collar nut 7 and which handle
on being moved forward on the rack 10 moves with it the collar nut 7 and forces
out of or along its supporting boss 6, the long collar or boss 1 which is prevented
from rotating by reason of its being held by means of the key 4 and slot 3 as
described.
And when the boss 1° moves forward its flange or collar 1 presses on the blade
spring 12, and the friction plates 13, 14, operate as ordinary.
When the catch 9 is raised, and the hand lever 9 is reversed, the friction on the
plates is reduced or taken off accordingley.
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;
Firstly The improved mechanism for applying and adjusting the friction
comprising the screw 1, boss 6, and collar nut 7, all in combination, and as herein
fully described and illustrated by annexed drawings.
