Improvements in or relating to Spinning, Doubling, Reeling, and
Winding Machines for Linen, Cotton and other Yarn.
I, HENRY MERCER GIRDWOOD, of Broughton Flax Mills, Salford, in the County
of Lancaster, Flax Spinner, do hereby declare the nature of this invention to be
as follows:-
My invention relates to improvements in spinning, doubling, reeling, and
winding machines for linen, cotton and other yarn, and the object of my inven-
tion is to make a more perfect yarn clearing or cleaning device so that the yarn
will not be chafed nor broken except when a piecing, lump or other imperfection
meets the clearer.
!
The clearers commonly in use are formed say of a piece of thin metal with a
fine slot or two pieces forming a slot through which the yarn passes, the slot in
the clearer being usually placed opposite the bobbin, cop or fly from which the yarn
is being drawn. In this construction the yarn meets both back edges of the
metal at a right angle, and the consequence of this is that the slot must be very
much wider than the thickness of the yarn to let it pass and even then it chafes
the yarn injuriously, and also allows some of the piecings and lumps to pass
through, thus lessening the value of the yarn. When the slot is made fine enough
just to allow the yarn where smooth to pass through and so stop the piecings and
lumps the yarn chafes and is cut against the back edges of the slot.
According to my invention I construct a clearer which obviates the defects
mentioned and allows the two parts of the clearer between which the slot is formed
to be set so close together that the yarn where smooth will only just pass freely
and consequently all piecings and lumps get cut, and this I effect by forming one
part of the clearer of a rod or bar with a round or curved edge over which round
edge the yarn first passes: the other portion of the clearer consisting of an
adjustable piece of metal which has a square or sharp edge and is set and secured
as near as desired to the first named piece.
In operation the clearer is placed to one side of the bobbin cop or fly so that
the yarn must bear against the round or curved surface and only come in contact
with the adjustable piece with the sharp edge when piecings or lumps come along
when they are at once caught and the yarn broken.

I, HENRY MERCER GIRDWOOD, of Broughton Flax Mills, Salford, in the County
of Lancaster, Flax Spinner, 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 invention relates to improvements in spinning, doubling, reeling and
winding machines for linen, cotton and other yarn, and the object of my inven-
tion is to make a more perfect yarn clearing or cleaning device so that the yarn
will not be chafed nor broken except when a piecing, lump or other imperfection
meets the clearer.
The clearers commonly in use are formed say of a piece of thin metal with a
fine slot or two pieces forming a slot through which the yarn passes, the slot in
the clearer being usually placed opposite the bobbin, cop or Hy from which the yarn
is being drawn. In this construction the yarn meets both back edges of the
metal at a right angle, and the consequence of this is that the slot must be very
much wider than the thickness of the yarn to let it pass and even then it chafes
the yarn injuriously and also allows some of the piecings and lumps to pass
through thus lessening the value of the yarn. When the slot is made fine enough
just to allow the yarn where smooth to pass through and so stop the piecings and
lumps the yarn chafes and is cut against the back edges of the slot.
According to my invention I construct a clearer which obviates the defects
mentioned and allows the two parts of the clearer between which the slot is formed
to be set so close together that the yarn where smooth will only just pass freely
and consequently all piecings and lumps get cut and this I effect by forming one
part of the clearer of a stud or pin with a round or curved edge over which round
edge the yarn first passes the other portion of the clearer consists of an
adjustable piece of metal which has a square or sharp edge and is set and secured
as near as desired to the first named piece.
In the accompanying two sheets of drawings-
Figure 1 shows in cross section part of a yarn reeling machine with my improved
clearer applied. Figure 2 is a plan of part of the bobbin rail illustrating the
arrangement of the improved clearers.
Figure 3 is an elevation, and Figure 4 a plan both on a larger scale of part
of the bobbin rail showing two bobbins and clearers.
In these views, designates the bobbin rail, 6 the bobbins, c the yarn, and
d the swift on which the yarn is reeled as usual.
Each clearer consists of two parts, namely a stud or pin e secured by a nut f to
a rail this rail being secured by bolts, screws or other fastenings to the hobbin
raila, which is slotted or cut away to receive the nuts and screws. The other
part of the clearer consists of the blade or cutter h rivetted to otherwise secured
to a bracket which is secured adjustably by screws to the rail g the screws
passing through slots in the rails."
The stud e and the bracket i may both be adjustable but in practice it is
preferable to adjust the bracket i only. In this case the screw holes of the rail g
to which the bracket i is fastened are slotted so that the cutters h can be set by
gauges at the proper distance from the studs e for each number or lea of yarn,
the heads of the screws being preferably underneath so that when the rail is
fastened to the bobbin rail a the clearer cannot be altered by the operative.
As shown clearly in the drawings, the clearer is placed out of the direct line
I

page_text: between the bobbin and the swift so that the yarn e must bear against the
rounded surface of the stud or pine and only come in contact with the cutting
edge of the blade h when piecings or lumps come along when they are at once
caught and the yarn broken.
To compensate for wear by the drag of the yarn the rail g can be taken off,
the nuts slackened, and the studs e or any of them turned partly round to bring
an unworn surface into position for the yarn to travel over, after which the
nuts are again tightened up and the rail g is replaced.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
-
1. In a yarn clearer, the combination with a stud having a smooth or rounded
surface against which the yarn bears on its way to the swift or equivalent part
upon which the yarn is wound, of an adjustable blade, the cutting edge of which
catches piecings or lumps in the yarn and breaks it down, substantially as herein
set forth.
2. In combination, the stud e, rail and the cutting blade attached to the
adjustable bracket i all substantially as herein set forth, for the purposes specified.
