Improvements in Pirn or Spool Winding Machines.
We JOE BOOTH WHITELEY and EDWARD WHITELEY, of the firm of William
Whiteley and Sons of Lockwood near Huddersfield in the County of York, Machine
Makers do hereby declare the nature of this invention to be as follows:-
The object of our invention in pirn or spool winding machines consists-firstly-in
means to be employed for putting drag or tension on the yarn so as to build up a
more firm and solid cop or bobbin ; and, secondly, in means to be employed for
cushioning "the faller rod each time it gets to the bottom of its downward movement
so as to cause it to rebound for the purpose of allowing the yarn (at that particular
point) to turn or twist sharply whereby firmness and solidity is given to the cop.
66
In carrying out the first part of our invention we attach to the faller rod, or to a
plate on the said faller rod, a small dead weight under which the yarn passes in its
way to the pirn whereby the necessary drag or tension is given to the yarn.
One side of the weight is rounded off so that when the yarn is first being put on
the pirn or when it is being pieced up; the said yarn will slip off the rounded part
and get under the weight.
Instead of the weight being a dead weight it may be hinged or otherwise
connected.
For cushioning the faller rod, we place a bracket or suitably shaped casting in a
convenient position under the faller rod, in which casting we fix a piece of india-
rubber or other suitable material so that when the faller rod descends to its lowest
position it strikes the india-rubber whereby it is caused to rebound and temporily
slacken the yarn allowing it to turn or twist quickly when reversing its motion.
The bracket or piece of india-rubber may be adjustable so as to regulate its position
with regard to the faller rod.

Improvements in Pirn or Spool Winding Machines.
We, JOE BOOTH WHITELEY and EDWARD WHITELEY, of the firm of William
Whiteley and Sons, 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 :-
The object of our invention in pirn or spool winding machines consists in means to
be employed for putting drag or tension on the yarn at a point just before it
commences to be wound on the spindle or pirn, whereby we are enabled to build up
a more firm and solid cop or bobbin.
In carrying out our invention we attach to the faller rod, or to a plate on the said
faller rod, a small dead weight under which the yarn passes on its way to the spindle
or pirn whereby the necessary drag or tension is given to the yarn.
.
One side of the weight is rounded off so that when the yarn is first being put on
the pirn or when it is being pieced up, the said yarn will slip off the rounded part and
get under the weight.
Instead of the weight being a dead weight, it may be hinged or otherwise
connected, and instead of employing a weight, one or more rollers may be used.

Such being the nature and object of our invention, we will now proceed to describe
the same more fully, and for that purpose make reference to the accompanying sheets
of drawings illustrative thereof, wherein Fig. 1 represents front elevation and Fig. 2
cross section of a well known form of apparatus for winding yarn onto a vertical
spindle or spool, commonly called "cone winding," comprising three conical bobbins
or rollers A working lightly upon centres a, and caused to revolve by frictional
contact with the revolving spindle or spool B. The conical bobbins are supported
in brackets C affixed to the top rail D of the machine. The faller rod is shewn
at E and is attached to and carried. by a vibrating lever arm F, connected to a
shaft G made to oscillate quickly by an arrangement of eccentrics, cams, or tappets at
the end of the framework of the machine in the ordinary manner. Onto the faller
rod E we prefer to place a V shaped plate H as set forth and described in the
Specification of prior Letters Patent granted to Joe Booth Whiteley and William
Whiteley, No. 5625, dated 7th May 1885. These V shaped plates, one of which is
employed for each spindle, are employed for the purpose of supporting the yarn close
up to its work or close to the spindle or pirn, so that immediately upon the yarn
leaving the edge of the said plate H it is taken up by the revolving pirn, and as the
faller rod has a quick up and down motion, the yarn is crossed whilst being wound
upon the cop, consequently it is firmly built up and when being sent across the loom
by the shuttle, the yarn so built upon the cop will not slip off or fluff, as is commonly
the case, and in order to place increased tension or drag on the yarn just before it is
being wound on the pirn, and also to ensure that the yarn never leaves the plate H,
but is at all times resting on such plate, we place, according to our present invention,
onto the said shaped plate a dead weight I underneath which the yarn B passes,
whereby the yarn is retarded or held in a state of tension at this particular part, but
between this dead weight I and the reel or bobbin from which the yarn being
unwound, it may be slack or without tension. The dead weight I is provided with
two holes, and is slipped onto two pegs or studs c, on which studs the dead weight
may rise and fall according to the various thicknesses of yarns or knotty places
thereon. It will be observed that the dead weight is rounded off at d, so that when
the yarn is first being put on the pirn, or when it has been pieced up, the yarn will
rest upon the upper part of the dead weight, but during the act of winding it works
off the round part and slips underneath the dead weight self-actingly.
Although we prefer to employ the dead weight I in combination with the V shaped
plate H, it is evident that the dead weight may rest upon the faller rod E, and instead
of employing a dead weight, such weight may be hinged with the loose or free end
resting upon the travelling yarn. In Fig. 3 we shew the application of an eylet e
through which the yarn passes.
Although we have shewn and described the application of our invention to the
system of winding illustrated in the drawings, our invention may be applied to cup or
other forms of winding.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :
In pirn or spool winding machinery, the use of a dead hinged weight I, or of
rollers or eyelet e, arranged in close proximity to the pirn or spindle for placing drag
or tension on the yarn, operated in the manner substantially as described and
illustrated.
