Improvements in and relating to Thread, Yarn, and like Winding
Machinery.
I, BRYCE MUIR KNOX, of the Firm of W. & J. Knox, Linen Thread Manufacturers,
Kilbirnie, Ayrshire, do hereby declare the nature of my invention to be as follows:-
This invention has reference to improvements in and relating to machinery for
winding thread, yarn, and the like on paper or other cops, and whereby the material
is wound in a series of diamond figures on the cop, half of the diamond being wound
the one way, and the other half the diagonally opposite way.
The machine would consist of a main base frame carrying a series of small frames
on top each consisting of two transverse vertical columns at short distances apart.
A longitudinal shaft would be carried in bearing brackets supported from base
frame and be driven through spur or other gearing and a belt from any adjacent
prime moving shaft.
A series of cams would be mounted on the longitudinal shaft one opposite the
central part of each small frame and each cam would preferably be formed in two
separate parts mounted by bosses and screw pins on shaft, and having an outer
annular end surface tapering in opposite diagonal directions towards points at the
semi-circumferences. A longitudinal shaft would be carried in bearings in the
small frames and be driven through spur or other gearing from the parallel cam
shaft, and separate spindles carried in eye bearings in each small frame would be
driven through spur gearing from the aforesaid shaft. The paper or other tapered
or conoidal cops on which the thread is to be wound would have their one end
mounted over the end of these spindles, while their other end would be carried on
a coller or ferrule mounted loose on a hand operated spindle.
Each of these latter spindles would be carried in eye bearings in the cheek
frames and projecting brackets, and be secured firmly to the latter by pinching
pins when the winding operations are proceeding, but when a cop is to be taken
out and replaced the motion of machine would be stopped by operating the belt
fork and these pinching pins would be slackened and the spindles made to slide
out of and return into working positions by means of a hand lever.
A crosshead or traversing frame would have two parallel rods screwed through
it and these rods would be mounted in eye bearings in each of the small frames,
parallel to the longitudinal shafts, and receive to and fro reciprocating movement
as hereinafter described.
A hollow projecting part from crosshead would have a surface plate mounted on
its end to bear on the surface of each cam, and a bolt or stud would pass through
this hollow part of crosshead and its end or an antifriction pulley on it work
between the adjacent outer end surfaces of the two parts of each cam. A smooth
surfaced horizontal plate would be mounted by underhung eye -bearings and

page_text: screwed by pinching screws to the upper reciprocating rod of crosshead, while a
corresponding surfaced plate would be mounted to bear over this and be formed
in two parts bolted together and each slit at the centre to slide on a fixed bar set
at an angle corresponding to that of tapered cop, but if parallel shaped cops that are of
equal diameter throughout are being wound this bar would be set parallel to
longitudinal spindles."
A counter-weighted bellcrank or kneed lever would be fulcrumed on an inverted
U shaped frame mounted above and carried on the last mentioned horizontal plate
and an eye and slit opening would be formed on the other arm of this lever to act
as a thread guide, the thread passing previously round tension pins and eyes on a
bracket plate on crosshead.
With this arrangement of mechanism each paper cop receives a continuous
motion of rotation from the spindle on which it is mounted, and at same time
each crosshead receives a to and fro reciprocating movement from the cams so that
the thread is wound on the cops in a series of diamond figures, the half of each
being in opposite diagonal directions. A pin is fitted in the top horizontal plate
and works in a slot in the lower horizontal plate secured to crosshead so as to
give the top plate and thread guide a slight to and fro transverse movement to
compensate for and agree with the taper on cop while the thread is being wound.

COMPLETE SPECIFICATION (AMENDED).
Improvements in and relating to Thread, Yarn, and like Winding
Machinery.
I, BRYCE MUIR KNOX, of the Firm of W. & J. Knox, Linen Thread Manufacturers,
Kilbirnie, Ayrshire, do hereby declare the nature of my invention, and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement, that is to say:
This invention has reference to improvements in and relating to machinery for
winding thread, yarn, and the like on paper or other cops, and whereby the material
is wound in a series of diamond figures on the cop, half of the diamond being wound
the one way, and the other half the diagonally opposite way.
And in order that my said invention and the manner of carrying same into
practice may be properly understood, I have hereunto appended a sheet of explana-
tory drawings, in which the same reference letters are used to indicate corresponding
parts in all the figures where shown.
Figure 1 is an end elevation of a winding machine as constructed in accordance
with my improvements.
Figure 2 is a transverse vertical section of the machine as taken on the line 3-3
of Figure 3 which is a plan view broken away of part of the machine.
Figure 4 is detached front view to an enlarged scale and
Figure 5 a detached side elevation of the traversing crosshead, cam and fittings.
Referring to these drawings:-
The machine would consist of a main base frame A carrying a series of small
frames on top, each consisting of two transverse vertical columns A¹ at short
distances apart. A longitudinal shaft a would be carried in bearing brackets a
supported from base frame A and be driven through spur or other gearing and a
belt from any adjacent prime moving shaft.

page_text: A series of cams would be mounted on the longitudinal shaft a one opposite
the central part of each small frame A¹ A and each. cam would preferably be
formed in two separate parts 6 6 mounted by bosses and screw pins on shaft a
and having an outer annular end surface & tapering in opposite diagonal directions
towards points at the semi-circumferences. A longitudinal shaft e would be
carried in bearings in the small frames A' and be driven through spur or other
gearing from the parallel cam shaft a and separate spindles d carried in eye
bearings in each small frame A would be driven through spur gearing from
the aforesaid shaft c. The paper or other tapered or conoidal cops e on which the
thread is to be wound would have their one end secured to or mounted over the
end of these spindles d while their other end would be carried on a collar or
ferrule d' mounted loose on a hand operated spindle e'.
Each of these latter spindies e, would be carried in eye bearings in the cheek
frames A and projecting brackets A and be secured firmly, to the latter by
pinching pins 2 when the winding operations are proceeding, but when a cop e
is to be taken out and replaced the motion of machine would be stopped by
operating the belt fork and these pinching pins would be slackened and
the spindles e' made to slide out of and return into working positions by means of
a hand lever e³.
A crosshead or traversing frame / would have two parallel rods f screwed
through it and these rods would be mounted in eye bearings in each of the small
frames A parallel to the longitudinal shafts, and receive to and fro reciprocating
movement as hereinafter described.
A hollow projecting part from crosshead would have a surface plate f
formed or mounted on its end to bear on the surface of each cam b b and a bolt or
stud would pass through this hollow part of crosshead and its end or an
antifriction pulley f on it work between the adjacent outer end surfaces 6 of the
two parts bbl of each cam. A smooth surfaced horizontal plate g would be mounted
by underhung eye bearings and screwed by pinching screws g g to the upper
reciprocating rod fi of crosshead f while a corresponding surfaced plate would be
mounted to bear over this and be formed in two parts h h screwed together and
each slit at the centre to slide on a fixed bar set at an angle corresponding to
that of tapered cop e, but if parallel shaped cops that are of equal diameter
throughout are being wound this bar would be set parallel to longitudinal spindles.
A counterweighted bellcrank or kneed lever i would be fulcrumed by an eye
boss loose on an adjustable spindle carried on a bracket on side of frame A
and a strap connection would be taken from the arm i of this lever i to a
moveable spindle having a vertical arm formed with an eye and slit opening to
act as a thread guide, the thread passing previously round tension pins and eyes k
on a bracket plate on crosshead. The spindle is moveable in eye bearings ♬
formed in a plate screwed to the top surface plate h. A hand operated spring
lever is used to engage with a projecting arm on spindle j to hold the thread
guide in its inactive position when drawn back from the cop spindle. The thread
guide arm is mounted adjustably in an eye on end of spindle so that it can he
turned round and set at the angle to suit angle of tapered cop."
With this arrangement of mechanism each paper cop e receives a continuous
motion of rotation from the spindle d on which it is mounted, and at same time
each crosshead f receives a to and fro reciprocating movement from the cams b
so that the thread is wound on the cops in a series of diamond figures, the half of
each being in opposite diagonal directions. A pin is fitted in the top horizontal
surface plate A and works in a slot in the lower horizontal plate y secured to
crosshead so as to give the top plate h and thread guide a slight to and fro
transverse movement to compensate for and agree with the taper on cop while the
thread is being wound.
spur wheels have to be changed to suit the thickness or variations of thread
to be wound.
When this machine is constructed for winding parallel cops the top surface

page_text: plate is cast in one with crosshead (and the lower plate g and sliding
inotion dispensed with) and in this case only one cam b b is necessary to be
mounted on the shaft a and the shaft a made a continuous longitudinal shaft
throughout machine, and driven through a crosshead such as f with stud f
carrying an antifriction pulley working in cam, so as to give a simultaneous to
and fro reciprocating movement to all the thread guides of machine. The vertical
arm of thread guide is in this case a fixture on moveable spindle j¹.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I wish it to be under-
stood that machines have been previously constructed, which like the machine
herein before described, wind a cop or ball of thread consisting of successive layers
in all of which the coiled portions of thread extending from end to end of the
cop have the same number of windings, and in which each coil of thread is
parallel throughout its extent to one of the preceding coils, and I do not claim
generally such machines, and I declare that what I claim is:-
First. A machine for winding thread, yarn, and the like constructed and operated
substantially as herein described in reference to and shown in the accompanying
drawings.
Second. In a machine for winding thread, yarn, and the like, the construction
and arrangement of traversing crossheads with thread guides and operating cams,
substantially as herein described in reference to and shown in the accompanying
drawings.
Third. In a machine for winding thread, yarn, and the like, the arrangement of
cop holding and detaching spindles and operating gear substantially as herein
described in reference to and shown in the accompanying drawings.
