PROVISIONAL SPECIFICATION.
An Improved Yarn-easing Motion for Spinning Mules or Twiners.
I PATRICK DUFFY of 62 Park Road Dukinfield in the County of Chester,
Cotton Mill Manager, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to provide means for easing the tension on the
yarn as the spindle carriage comes near to the end of its stretch without allowing
the same to become slack and so form what are known as "snarls."
For this purpose I fix upon the headstock of the mule or twiner a bracket
provided with a slot in which is adjustable the pin or fulcrum of a lever, one
arm of which is made with an inclined surface at the end, and the other is
provided with a movable weight which is adjustable to suit the "count
of yarn
to be spun.
"
On the counter-faller shaft is fixed a curved arm or lever the free end of which
is provided with a slot in which is adjustable a pin or stud carrying a friction
bowl.
"
As the carriage comes near to the end of its stretch this bowl runs up the
inclined surface above referred to and thus relieves the pressure of the counter-
faller wire and eases the strain upon the
"snarls." More or less tension to Put the yarn without allowing it to form into
count of yarn being spun or doubled
can be given by adjusting the position of the movable weight upon the lever
carried by the bracket attached to the headstock of the mule or twiner as
aforesaid.

COMPLETE SPECIFICATION.
An Improved Yarn-easing Motion for Spinning Mules or Twiners.
I PATRICK DUFFY 62 Park Road Dukinfield Cheshire, Cotton Mill Manager,
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:-
To the counter faller shaft on any mule or twiner I fasten the lever A having
the antifriction bowl B attached thereto and made adjustable. To the outer end of
headstock frame I attach the fixing C, the same being prepared to receive the
lever D and being adjustable, on the lever D I place a weight E prepared to slide
nearer to or further from the fulcrum and so adjust the pressure on the inclined
plane of lever D, then the mule carriage in its outward movement brings the
antifriction bowl B in contact with and on the top of lever D when by reason of
the inclined plane the weight E is lifted from the stop F and thus throws its
pressure on the antifriction bowl B which in turn imparts pressure to the counter
faller shaft in a reverse direction to that got from the salmon head reducing the
tension on the yarn during the backing off and also on the inward run of the
carriage until the antifriction bowl B has left contact with the lever D.

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 which [
claim is
A new and improved method of easing the yarn in spinning mules and twiners
during the backing off, and also during the inward run of the carriage necessary
to wind the yarn from the nose to the bottom of the chase, substantially as
described in the Specification and illustrated by the accompanying drawings.
Dated this 20th day of June 1894.
