PROVISIONAL SPECIFICATION.
Improvements in Pirn Winding Machines.
I, WILLIAM WHITELEY, of the Firm of William Whiteley and Sons, Limited,
of Lockwood, near Huddersfield, in the County of York, Machine Makers, do.
hereby declare the nature of this invention to be as follows:-
My improvements have been designed for the purpose of winding yarn onto long
pirns, but the improvements are also applicable for winding yarn onto the
short pirns.
In carrying out my invention I make the central portion of the spindle square,
or of an angular shape, but the upper and lower portion of the said spindle is
formed round in cross section. The foot of the spindle is inserted into a hole in a
block, whilst the upper portion of the spindle is inserted into a hole formed in a
bracket, the spindle therefore running in bearings at both ends. The block in
which the foot of the spindle rests, carries a wharle having a clutch formed on its
upper portion gearing into a corresponding clutch sliding on the square part of the
spindle, therefore when the clutches are in gear (the wharle being driven by a band)
rotary motion is imparted to the spindle.
The pirn, which is made with a round hole, is driven by a block resting on the
top of the pirn, such block being made with a square hole in which the spindle fits,
therefore it must be understood that the wharle drives the spindle, the spindle
drives the block on the head of the pirn, and the block imparts rotary motion
to the pirn. When the pirn is full of yarn it will have raised up the spindle
sufficiently far as to bring the square hole in the block to the round part of the
spindle, consequently the driving block ceases to revolve (although the spindle
is revolving) and the pirn will remain inoperative until it is changed for an
empty one. When the square hole in the block is lowered to the square part of the
spindle it will be driven as before for the purpose of winding yarn upon the pirn.
When an end breaks the attendant by means of a trigger or finger disengages
the clutch box which drives the spindle so that the pirn is at rest until the
broken ends are pieced up. When this is done the clutches are again engaged
and the spindle caused to rotate.
By supporting the spindles at both ends they are steadied and 1 am enabled to
run them at a greatly increased speed and I am also enabled to wind yarn upon
much longer pirns than is usually the case.

1, WILLIAM WHITELEY, of the Firm of William Whiteley and Sons, Limited,
of Lockwood, near Huddersfield, in the County of York, Machine. Makers, 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 :-
My improvements have been designed for the purpose of winding yarn onto.
long pirns, but the improvements are also applicable for winding yarn onto
short pirns.
Such being, the nature and object of my invention. I will now describe. more
fully how the same is to be carried into practical effect, and for that purpose make
reference to the accompanying sheet of drawings, wherein Fig. I is sectional
elevation of my improved arrangement of mechanism and Fig. 2 is plan of
same.
A represents three winding cones, B the pirn or bobbin, and C the lifting rail
employed for traversing the yarn up and down the cones all arranged in the
ordinary manner. The spindle is shewn at D, and it is formed square or angular
in cross section except the top and bottom parts a and b which are round in cross
section. The foot of the spindle is inserted into a hole formed in the block E.
whilst the upper end of the said spindle is inserted into a hole formed in a movable
bracket F, the spindle therefore runs in bearings at both ends and is kept perfectly
steady whilst revolving. The block E in which the foot of the spindle rests, is
secured to a wharle G formed with notches or half clutch c in its upper portion,
such half clutch. gearing with a corresponding clutch d capable of sliding vertically
on the square part of the spindle; therefore when the said clutches are in gear
(the wharle being driven by, a band) rotary motion is imparted to the spindle. The
pirn B' which is made with a round hole is driven by a block H resting on the top
of the said pirn, such block being made with a square hole so as to fit the spindle,
it will therefore be understood that the wharle G drives the spindle D the spindle
drives the block H on the head of the pirn and that the block imparts rotary motion
to the pirn.
When the pirn is full of yarn, it will be raised automatically up the spindle
as shewn in dotted lines sufficiently far, as to bring the square hole in the block H
to the round part of the spindle a consequently the said block ceases to revolve
although the spindle is running and the pirn will remain inoperative until it.is
chianged for an empty one. When the square hole in the block is lowered. upon
the square part of the spindle, the said block will be driven as before for the purpose.
of winding yarn, upon the pirn. The full lines in the drawings shew the pirn in
its lowest position when empty. When an end of thread. breaks,, the attendant.
lifts up the trigger or finger I placing the lower notch e onto the rail J so as to.
disengage the clutches which drive the spindle. This action causes the spindle
to stop and the pirn is then at rest until the broken ends are pieced' up. When this
is done the trigger I is operated in the reverse direction whereupon the clutches
are again engaged and the spindle caused to rotate. When changing a pirn,
the top bracket F is raised on the stud L sufficiently high as to remove the
peg from a hole in the standard M. When this is done the bracket F is
moved sideways on stud L as shewn in dotted lines in the plan Fig. 2 whereby
the pirn can be removed and a fresh one substituted after which the bracket F
is put back again.
c
By supporting the spindles at both ends in the manner herein shewn in the

page_text: drawings the said spindles are steady and I am enabled to run them at a greatly
increased speed and I am also enabled to wind yarn upon much longer pirns than
is usually the case.
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 what I
claim is :-
Firstly. In pirn winding machines, the use therein of a spindle of two sizes or
sections, together with the pirn driving head H arranged and operating in the
manner herein shewn and described.
Secondly. In pirn winding machines, the use therein of a spindle of two sizes
or sections, together with the pirn driving head H, in combination with driving
clutches c and d as shewn and described.
Thirdly. In a pirn winding machine, the use therein of a spindle of two sizes or
sections, driving head H, clutches c and d, operating trigger I and swinging
bracket F, all employed in the manner and for the purposes herein described.
