Improvements in Machines for Winding Yarn upon Pirns
or Quills.
I, JOSHUA VALENTINE EVES, of The Forth River Mills, Belfast, in the County
of Antrim, Ireland, Mill Manager, do hereby declare the nature of this invention
to be as follows:-
This invention relates to that class of machine which are known as cup winding
frames and is designed to enable the yarn to be wound onto the pirn or quill in such
machines without putting any appreciable drag or tension upon the yarn, and at the
same time wind the yarn tight and hard thereon.
Hitherto in these machines the yarn has been guided or delivered from the
traverse guide onto the pirn or quill in the cup and unless the pirn or quill was
truly formed to accurately fit the inside of the narrow part or shank of the cup a
considerable amount of drag or tension was put upon the yarn and it has only been
possible to use tapering quills with coarse or strong yarns.
It consists essentially in the application to the cup of a presser that delivers the
yarn upon the quill the presser acting at the same time as the traverse guide and
being so formed that the pressure may be concentrated upon the layer of yarn that
is being wound.
In carrying out the invention I apply to the traverse guide any suitable
mechanisin or attachment a presser which will deliver the yarn on to the pirn or
quill. This presser is held down by a weight or spring of suitable strength to
maintain it against the varying diameter or thickness of the pirn as the yarn is
wound or built up thereon."
I at present prefer to construct the presser attachment with an upright standard
or bracket affixed to the traverse shaft with an arm or lever pivoted at the upper
end. This pivoted arm or lever carries at its outer end either pivoted or otherwise
attached a bracket or other connecting piece to which is adjustably fixed by a set
screw or other means the presser and guide. The end of the presser is formed to
receive and deliver the yarn onto the quill and is preferably narrow to bear upon
the layer of yarn being laid on. The pivoted arm is held down by a weight or
spring adjusted to give the required amount of pressure.
The presser passes down inside the slot of the cup and lays the yarn hard on the
flat part of the tube at the beginning of the layer and on the gradually diminishing
diameter of the taper tube or quill. The spring or weight keeps it tight down and
the pressure
concentrated on the layer of yarn being wound on.
By this arrangement I am enabled to wind very fine yarns upon pirns or quills
with the minimum of breakages and without drag or tension on the yarn and at the
same time wind the yarn hard and compact upon the quill.

Improvements in Machines for Winding Yarn upon Pirns
or Quills.
1, JOSHUA VALENTINE EVES, of The Forth River Mill, Belfast, in the County
of Antrim, Ireland, 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 :--
This invention relates to that class of machines which are known as cup winding
frames and is designed to enable the yarn to be wound onto the pirn or quill in such
machines without putting any appreciable drag or tension upon the yarn, and at the
same time wind the yarn tight and hard thereon.
Hitherto in these machines the yarn has been guided or delivered from the
traverse guide onto the pirn or quill in the cup and unless the pirn or quill was
truly formed to accurately fit the inside of the narrow part or shank of the cup a
considerable amount of drag or tension was put upon the yarn and it has only been
possible to use tapering quills with coarse or strong yarus.
It consists essentially in the application to the cup of a presser that delivers the
yaru upon the quill the presser acting at the same time as the traverse guide and
being so formed that the pressure may be concentrated upon the layer of yarn that
is being wound.
The invention will be fully described with reference to the accompanying
drawings in which sufficient of the operative parts of a cup winding machine are
shown to illustrate it.
Fig. 1. End elevation (partly in section) of the parts of the machine in conjunction
with which my invention works.
Fig. 2. Side elevation of my improved presser detached from the machine (drawn
to an enlarged scale).
Fig. 3. Front elevation of same.
Fig. 4. Plan.
The spindle A upon which the pirn is wound, the cup B, the sliding bracket C by
which the spindle is pressed forward, the pivoted weighted lever c attached thereto,
and the fixed inclined guide D upon which the weighted lever slides are constructed
and operated in any ordinary or well known manner.
I remove the ordinary wire or thread guide from the oscillating shaft E and
substitute therefor my improved appliance which serves as a thread guide to deliver
the yarn onto the pirn or quill and also as a presser to build it up tightly thereon
and is actuated by the oscillating movement of the shaft E.
I affix to the shaft E a rod or upright F and to the upper end of this rod I pivot
an arm or lever G. The lever G is preferably of shape and its movement on the
pivot g is restricted by the pin inserted in the rod F. To the upper end of the
lever G I hinge or pivot a bracket H which has a to and fro movement on
the pivot h. This bracket extends out at one side to overhang the cup B in which
the pirn is wound and to the overhanging part is adjustably affixed by the set screw i
(or other means) the presser and guide I. The presser and guide I is preferably
formed of wire and is sufficiently narrow to pass through the slot in the top of
the cup B. The lower end of the presser I is formed of the shape shown (or other
suitable shape) to receive and deliver the yarn onto the pirn or quill and presses
directly on the layer of yarn as it is wound on. The pivoted arm is held down by
a weight Jattached to a spring j adjusted to give the desired amount of pressure
upon the pirn.
The presser and thread guide I passes through the slot in the cup and lays the
first layer of yarn hard upon the flat or parallel or taper part of the paper or
wooden tube or quill at the beginning of the winding, and on the gradually
diminishing diameter of the taper tube or quill as the winding proceeds. The

page_text: weight and spring J and j keep the presser down with the required degree of
pressure and also allows it to press equally on all parts of the inclined nose or face
of the pirn as it is moved backwards and forwards by the oscillating of the shaft E
the pressure being concentrated on each layer of yarn as it is wound on.
By this arrangement I am enabled to wind very fine yarns upon pirns or quills
with the minimum of breakages and without drag or tension on the yarn and at the
same time wind the yarn hard and compact upon the quill.
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 :-
1. In a cup winding machine the combination with the spindle and cup of a
presser and guide moving to and fro upon the surface of the yarn and pressing each
layer of the yarn as it is wound substantially as described.
2. In a cup winding machine the combination with the cup and spindle and other
ordinary operative parts of the machine, of the rod F affixed to the oscillating
shaft E, the arm or lever G pivoted to the top of the rod F, the bracket H pivoted
thereto to carry the presser guide, and the presser guide I to guide the yarn and
press each layer hard as it is wound substantially as described.
3. In a cup winding machine the presser for guiding the yarn and pressing it
hard upon the pirn constructed and arranged substantially as described.
