PROVISIONAL SPECIFICATION.
Improvements in or connected with Machines for Winding Yarn
on to Pirns, Bobbins, or Quills.
I, THOMAS HENRY SPENCE, of Portadown, in the County of Armagh, Ireland,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
The invention relates to that class of winding machines which are employed
more particularly for winding linen yarn from hanks and cross wound tubes or
spools on to weavers bobbins, pirns, paper quills or the like for insertion in the
shuttle for weaving.
The invention consists essentially in the combination with the thread guide or
other part of the machine of two discs or washers made of glass, delf, brass, iron,
steel or other suitable substance mounted upon a horizontal bar or rod of wood,
metal, glass. or other material and maintained closely pressed together by one or two
spiral or other springs pressing against the outer side of one or both of them to
form a tension device for the thread or yarn to pass through.
In carrying out the invention I attach to a rod or rail placed in front of the
machine or to the slubber washers or to other convenient brackets or part of the
machine by means of an arm or otherwise, a bar or stud preferably placed
horizontal, and loose on this bar or stud are placed two discs which can be
compressed tightly together by means of one or two springs.
The bar or stud may be of iron, steel, brass, wood, glass or other material aud
the discs may be of steel, iron, brass, glass, delf or other material.
When one spring only is used this spring is placed on the horizontal bar or stud
which bears between one of the discs and a nut or washer placed upon the end by
which the pressure exerted by the screw can be adjusted.
When two springs are used the discs are placed in centre of horizontal bar with
a spring bearing against each and a nut or washer placed upon each end of this bar
and by which the pressure is regulated.
The thread or yarn passes between these discs the tension exerted by which
thereon can be regulated and adjusted as desired and its advantage consists in the
ease with which this can be done.

Improvements in or connected with Machines for Winding Yarn
on to Pirns, Bobbins, or Quills.
I, THOMAS HENRY SPENCE, of Portadown, in the County of Armagh, Ireland,.
Manufacturer, do bereby 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:—
The invention relates to that class of winding machines which are known as cup
winding frames and are employed for winding linen or other yarn from hanks and
cross wound tubes or spools onto weavers bobbins, pirns, paper quills or the like
for insertion in the shuttle for weaving.
The invention consists essentially in the combination with the thread guide or
other part of the machine of two discs or washers made of glass, delf, brass iron
steel or other suitable substance mounted upon a horizontal bar or rod of wood,

It will be fully described with reference to the accompanying drawings in which
sufficient of a cup winding machine is shown to illustrate the invention.

Fig. 5. Side elevation of same.
Fig. 6. Front elevation of another modification.
The framing A the spindle B the cup C the vibrating shaft D and the thread
guide E and the slubber washers F are all constructed and operate in the ordinary
manner.
To any suitable rod or bracket in front of the machine such as to the shaft or
brackets which support the slubber washers F I attach a bar or stud G and on the
bar or stud G are placed two discs or washers H side by side. The discs H are
pressed tightly together by springs I placed on one or both sides of them.
The bar or stud G is preferably placed horizontally a short distance in front of
the yarn clearer J and may be made of iron, steel, brass, glass, wood, or other
material and the discs H may be of steel, iron, brass, glass, delf or other material.
When one spring I only is used this spring is placed on the horizontal bar or
stud which bears between one of the discs H and a mut or washer g placed upon
the end by which the pressure exerted by the screw can be adjusted.
When two springs I are used (as in Fig. 6) the discs H are placed in centre of
horizontal bar with a spring bearing against each and a nut or washer placed upon
each end of the bar G by which the pressure is regulated.
The yarn as it is wound off the rolls or hanks and is wound onto the pirn in the
cup C is passed between the discs H. The tension exerted by these discs on the
yarn can be regulated and adjusted as desired quickly and easily by, the nut g and
screw on the end of the bar G. By this means the yarn is delivered to the cup so
that it can be wound upon the pirn at an even tension throughout.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
In a cup winding machine the combination with the yarn guide and winding cup
of a tension device consisting of two discs held pressed together by springs on a
horizontal stud placed in front of the machine and attached to the slubber washers
or other convenient position substantially as and for the purpose described.
