Improvements in Machinery for Clearing Yarn or Thread and for
Winding it in Conical Layers on to Bobbins, Pirns, Cops, or
Paper Tubes.
We, JOHN BOYD and THOMAS ALEXANDER BOYD of Shettleston in the
County of Lanark, North Britain, Engineers do hereby declare the nature of this
invention to be as follows:-
Our said invention relates to improvements designed to be applied to winding
machines of the kind described in the Specification of Letters Patent granted to
us No. 2226 of 1873 and shown particularly at Figures 1 and 2 of the drawings
annexed to said Specification, which improvements can also be advantageously
adapted to various other kinds of winding machines.
Our improved mechanism is very suitable for winding certain kinds of yarn
which require to be wound with a considerable amount of pressure and on this
account are apt to be injured by excessive friction when ordinary shaping cups are
used such as are shown and described in the Specification before referred to, the
injury to such yarn being obviated by our improved mechanism.
In carrying out our present invention instead of ordinary 'shaping' cups anti-
friction shaping cones are used which cones are made, arranged, carried and
lubricated in an improved manner. The cones are by preference tapered to suit
the proportions of the conical surface of the pirns or cops which they are intended
to shape. In all cases the larger and smaller diameters of the pirn or cop are
made to come in contact with and drive respectively the larger and smaller
diameters of its cone or cones, one, two or three such cones being used with each
winding spindle according to circumstances. Each cone bears on the point of its
own spindle on which it revolves, by the pressure of the pirn which drives it, and
the spindle of each cone may either be a live spindle fixed into and forming part of
the cone, or the cone may be drilled out sufficiently so as to be carried by and
revolve easily on the point of a dead spindle. When the shaping cone has its
spindle fixed to and forming part of it, the cone is made hollow at its large end and
solid at its small end into which its spindle is fixed and the spindle revolves loosely
in a footstep oil bearing carried inside of the cone, which arrangement is preferred
when the footstep oil bearing is held in a position which helps it to retain its oil,
but in other cases it is better for the purpose of retaining the oil to have the cone
simply revolving on the point of its spindle and not fixed to it. The footstep sockets
or the spindles which carry our improved shaping cones may either be fixed rigidly
to the brackets or rails of the winding machine or may be carried on weighted or
spring controlled bell-crank levers or swivel brackets so as to accommodate them-
selves automatically to the varying diameters of the stems of the pirns or paper
tubes on to which the yarn requires to be wound.
In one arrangement of our improved mechanism for winding yarn in conical
layers on to bobbins or paper tubes one of our improved shaping cones is carried on
a suitably shaped horizontal bracket fixed to the spindle rail and in this case the
socket in which the spindle of the shaping cone runs is placed immediately under
the tapered part of the piru and the horizontal bracket has a guiding eye at its
outer end to guide the stem of the pirn and to hold it when pressed forward by its
spindle in contact with the shaping.cone.
In a second arrangement the shaping cone is carried on the horizontal' bracket
by a bell-crank weighted or spring controlled lever so as to allow the shaping
cone to accommodate itself to the varying diameters of the stems of pirns or paper
tubes

In a third arrangement two of the shaping cones are mounted on fixed'
studs or dead spindles one on each side of the pirn which they are required
to shape.
In a fourth arrangement two of the shaping cones, one on each side of the pirn,
are carried on swivel brackets the latter being drawn together at their outer ends
so as to allow the shaping cones automatically to accommodate themselves to the
varying diameters of the stems of pirns or paper tubes which they are required
to shape.
In a fifth arrangement in which two of the improved shaping cones are adapted
to a vertical winding arrangement with an upward pressure of the pirn the spindles
of the shaping cones are by preference arranged to work in step sockets for the
purpose of retaining their oil.
In a sixth arrangement in which two of the improved cones are adapted to a
vertical winding arrangement with a downward pressure of the pirn the spindles on
the points of which the cones work are by preference dead spindles for the purpose.
of retaining their oil..
In the two latter vertical spindle arrangements one, two or three of the improved
shaping cones may be used to each pirn or spindle.
The yarn to be wound is passed through improved adjustable clearers the two
parallel clearing edges of which are held together by two parallel bars or links
which swivel on centres or by elastic springs fixed at their ends to the clearing
plates, one of each pair of clearing plates which form each clearer being fixed to a
traverse bar or other part of the machine and the other being adjustable by means
of a screw or otherwise to increase or diminish the gauge of the slit through
which the yarn is to be passed for the purpose of being cleared.
The improved clearers can be arranged, so that two, three or more slits can be
opened or closed at one time.

Improvements in Machinery for Clearing Yarn or Thread and for
Winding it in Conical Layers on to Bobbins, Pirns, Cops, or
Paper Tubes.
We, JOHN BOYD and THOMAS ALEXANDER BOYD, of Shettleston, in the
County of Lanark, North Britain, Engineers, 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 :-
Our said invention relates to improvements designed to be applied to winding
machines of the kind described in the Specification of Letters Patent granted to
us No. 2226 of 1873 and shewn particularly at Figures 1 and 2 of the drawings

Our improved mechanism is very suitable for winding certain kinds of yaru
which require to be wound with a considerable amount of pressure and on this
account are apt to be injured by excessive friction when ordinary shaping cups are
used such as are shewn and described in the Specification before referred to, the
injury to such yarn being obviated by our improved mechanism.
I
In carrying out our present invention instead of ordinary shaping cups anti-
friction shaping cones 17 are used and are arranged in an improved manner.
The
cones are by preference tapered to suit the proportions of the conical surface of
the pirns or cops 18 which they are intended to shape. In all cases the larger and
smaller diameters of the pirn or cop are made to come in contact with and drive
respectively the larger and smaller diameters of its cone or cones one or two such
cones being used with each winding spindle according to circumstances.
Each cone
bears on and against the point of its own internal spindle 19 on which it revolves,
by the pressure of the pirn 18 which drives it, and the internal spindle 19 of each
cone may either be a live spindle fixed into and forming part of the cone as in
Figures 1, 2, 3, and 9, or the cone may be drilled out sufficiently so as to be
carried by and revolve easily on the point of a dead spindle as shewn in Figs. 4, 5,
6, 7, 10 and 11. When the shaping cone has its spindle fixed to and forming part
of it, the cone is made hollow at its large end and solid at its small end into which
its spindle is fixed, and the spindle revolves loosely in a footstep oil bearing 20
carried inside of the cone, which arrangement is preferred when the footstep oil
bearing is held in a position which helps it to retain its oil as in Figures 1, 2, 8
and 9 but in other cases it is better for the purpose of retaining the oil to have the
cone simply revolving on and bearing on the point of its spindle and not fixed to it.'
The footstep sockets 20 or the dead spindles 19 which carry our improved shaping
cones may either be fixed rigidly to the brackets 16 or rails 21 of the winding!
machine or may be carried on weighted or spring-controlled bell crank levers or
swivel brackets 22 as in Figures 3, 6 and 7 so as to accommodate themselves
automatically to the varying diameters of the stems of the pirns or paper tubes 18
on to which the yarn requires to be wound.
In one arrangement of our improved mechanism for winding yarn in conical
layers on to bobbins or paper tubes Figs. 1 and 2 one of our improved shaping
cones 17 is carried on a suitably shaped horizontal bracket 16 fixed to the spindle
rail 21 and in this case the socket in which the spindle of the shaping cone runs is
placed immediately under the tapered part of the pirn 18 and the horizontal
bracket 16 has a guiding eye 23 at its outer end to guide the stem of the pirn 18
and to hold it when pressed forward by its spindle 24 in contact with the shaping
cone 17.
In a second arrangement Figure 3, the shaping cone 17 is carried on the
horizontal bracket by a bell crank weighted lever 22 so as to allow the shaping
cone to accommodate itself to the varying diameters of the stems of pirns or paper
ubes 18 being wound by it.

page_text: In a third arrangement Figs. 4 and 5 two of the shaping cones 17 are mounted
on fixed studs or dead spindles 19, one on each side of the pirn 18 which they are
required to shape.
In a fourth arrangement Figs. 6 and 7 two of the shaping cones 17 one on each
side of the pirn or cop 18 are carried on swivel brackets 22, the latter being drawn
together at their outer ends by a cord and weight 25, the weight being suspended
to the end of the cord and the cord being passed through an eye formed at the end
of an arm of one swivel bracket 22 and connected to the arm of the other swivel
bracket 22 so as to allow the shaping cones 17 automatically to accommodate
themselves to the varying diameters of the stems of pirns or paper tubes which they
are required to wind.
In a fifth arrangement Figs. 8 and 9 in which two of the improved shaping cones
are adapted to a vertical winding arrangement of spindles 24 with an upward
pressure of the pirn 18 the internal spindles 19 of the shaping cones 17 are by'
preference arranged to work in step sockets 20 for the purpose of retaining
their oil.
The cones 17 are by preference placed opposite each other one on each side of
the pirn 18 and the sockets 20 are carried in a suitably shaped vertical bracket 16
fixed to the spindle rail 21, and the vertical bracket has a guiding eye 23 formed
at its top end to guide the stem of the pirn 18 and to hold it when pressed upward
by its spindle 24 in contact with its shaping coues 17.
-
In a sixth arrangement Figs. 10 and 11, in which two of the improved cones 17
are adapted to a vertical winding arrangement of spindle 24 with a downward
pressure of the pirn 18 the spindles 19 on the points of which the cones work are
by preference on dead spindles for the purpose of retaining their oil.
The cones 17 are by preference placed opposite each other one on each side of
the pirn 18 and the dead internal spindles 19 are carried by a suitably shaped
vertical bracket 16 fixed to the spindle rail 21 and the vertical bracket has a
guiding eye 23 formed at its bottom end to guide the stem of the pirn 18 or the
spindle 24 and to hold the pirn or cop 18 when pressed downwards by its spindle 24
in contact with its shaping cones 17.
Instead of the stem of the pirns or cops being guided by an eye 23 formed at the
top or bottom of the vertical brackets 16, the shape and position of these brackets
may be changed so that guiding eyes for the stem of the pirns may be formed in
the longitudinal rails 21 which carry the vertical brackets.
Common methods of guiding the yarn on to the conical surfaces of the pirns or
cops 18 as the latter are being wound are shown in Figs. 1, 8, 9, 10 and 11.
The yarn to be wound is passed through improved adjustable clearers 15, Fig. 1,
consisting of two plates the two parallel clearing edges of which 26 and 27
Figs. 12, 13 and 14, are held together by two parallel bars or links which swivel
on centres or by elastic springs 28 and 29, one of each pair of clearing plates 26
which form each clearer being fixed by a bolt or set screw 30 passed through a
slot 31 to a traverse bar 32 or other part of the machine and the other plate 27
being adjustable by means of a screw 33 or like means to increase or diminish the
gauge of the slit formed by the contiguous clearing edges of the plates through
which the yarn 34 is passed for the purpose of being cleared, as shewn in
Fig. 1.
The improved clearers can be arranged so that two, three or more slits can be
opened or closed at one time.
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 :-
1. The improved construction of adjustable clearers for clearing yarn in the
process of winding in which clearing plates having their contiguous clearing edges
held exactly parallel apart by parallel bars or links or elastic springs are brought
further from or nearer to each other so as to increase or diminish the gauge of the
..

page_text: clearing slit by means of a set screw or like means as herein described with
reference to Figs. 1, 12, 13 and 14 of the accompanying drawings.
2. The improved anti-friction cone formers consisting of one or two cones, each
mounted so as to revolve on and against the point of a live or dead spindle and
each dead spindle or each socket carrying its live spindle being either rigidly fixed
or carried by a bell crank or swivel joint and each cone or pair of cones working in
combination with a stationary guide eye for guiding the stem of the pirn or cop to
keep the latter in contact with the cone or cones when the yarn is being wound on
to the pirn or cop substantially as described with reference to Figures 1 to 11 of
the accompanying drawings.
