Improvements in and relating to Machines for Winding Yarn, Twine
or Thread into Rolls.
We, HENRY CAMERON and JOHN MACLAREN MALLOCH, both of Blackness
Foundry, Dundee, in the County of Forfar, Scotland, Engineers, do hereby
declare the nature of this invention to be as follows:-

This invention relates to improvements in machines for winding yarn, twine
or thread into rolls, the object being to instantaneously reverse the direction
of motion of the traverse with the minimum of vibration, jar, or shock on
the framing due to inertia of parts, so that the roll may be built to hold together
when removed from the spindle, and that it may be of the correct shape.
In carrying out our invention according to one modification, we cause two
wheels, which are preferably of heavy rim section so that they may act as fly-
wheels, to rotate in opposite directions and at a uniform speed about a common
axis. These two wheels are placed close to one another, but with a space
between them. In this space are two compound levers placed opposite one
another. Each compound lever oscillates in a plane normal to the axis of the
wheels while in addition their supplementary levers oscillate in a direction at
right angles to same, that is to say the compound lever as a whole oscillates
in one plane while the supplementary lever in addition oscillates in another.
The sides of the wheels next the compound levers are provided with hardened
steel stops so placed relative to each other that such compound levers are alter-
nately actuated by the one wheel and the other. To facilitate the engaging of
each supplementary lever with each wheel in succession they are so hinged or
jointed that they may be made to incline towards the one or the other wheel,
such inclination being brought about by suitable stationary inclined guides at
the periphery of the wheels. Each of these supplementary engaging levers
oscillates from side to side towards the one wheel or the other by means of these
inclined guides, their final and extreme position when engaged with a wheel
being determined by means of pointed spring push knobs, one of which is on
each main lever. Each compound lever forms part of, or is mounted upon a
sleeve upon which one of the aforesaid wheels rotates, its other extremity having
upon it a lever to which the traverse rods are coupled. A similar compound
lever and its appurtenances is placed opposite as has already been pointed out,
the two sets being so arranged as to be in equilibrium when in action.
When working, their action is such that the uniform rotation of the two
wheels in opposite directions, by means of the balanced mechanism described,
causes the transverse rods to reciprocate at such a rate as to build suitable rolls
of twine or thread with the minimum vibration or shock to the frame of the
machine.

page_text: In another modification we may cause the two wheels to rotate in the same
direction at a uniform rate about a common axis. Each compound lever is
pivoted on an axis normal to the axis about which the wheels rotate, its supple-
mentary lever being pivoted in such a manner that it can oscillate at right
angles to the main lever while at the same time it oscillates along with it. On
the periphery of each wheel are hardened steel stops with which each extremity
of the supplementary lever engages in turn. Fixed inclines cause the one
extremity or the other of such supplementary lever to approach one or the other
wheel a certain distance, after which a pointed spring push knob acting on a
projection on the lever causes it to fully engage with one or the other wheel, and
so causes the main lever to oscillate and the "traverse" to reciprocate. The
duplex levers are balanced for the purpose previously described.
In a third modification we cause a cylinder or drum to rotate at a uniform
speed. On its cylindrical surface is an endless groove or its equivalent, co
arranged that it makes the extremity of a lever which is in contact with it to
oscillate from side to side at a uniform rate, the axis of such lever being at
right angles to the axis of the cylinder. Projecting on each side of the afore-
said oscillating-lever and moving in unison with it, are two other levers to whose
extremities are coupled connecting rods, their other extremities moving in
guides.
Hardened steel projections on such connecting rods engage with similar steel
stops on the periphery of steel collars fixed on the cam cylinder shaft, that is
to say each rod alternately is pushed by the corresponding projection on its collar.
A similar set of levers are actuated by the cylinder at the opposite side, in this
manner balancing the forces tending to cause vibration in the machine. Other
levers may be fixed on the arbors of the oscillating levers, and to these the con-
necting rods for actuating the traverse gear may be attached.
The rate at which the levers oscillate and the projections on the collars rotate,
may or should be nearly uniform, that is to say the diameter of the cylinder
where the endless groove is may be larger than the portions where the projections
are.
The action of the combination is as follows:-The cylinder as it rotates causes
the levers to oscillate by means of the endless groove. The oscillation of such
levers, by means of their essential mechanism, would cause the traverse gear to
reciprocate, but in time the groove would wear at certain points and so set up
undue vibration in the machine. The supplementary mechanism, consisting of
the connecting rods and the projections on the collars are so arranged that they
give the needful push to the oscillating lever at the critical moment and thus
reduce the wear and tear on the cam thereby building a more perfect roll.

COMPLETE SPECIFICATION.
Improvements in and relating to Machines for Winding Yarn, Twine
or Thread into Rolls.
We, HENRY CAMERON and JOHN MACLAREN MALLOCH, both of Blackness
Foundry, Dundee, in the County of Forfar, Scotland, Engineers, do hereby
declare the nature of this invention and in what manner the same is to be per-

page_text: formed, to be particularly described and ascertained in and by the following
statement;-
This invention relates to improvements in machines for winding yarn, twine
or thread into rolls, the object being to instantaneously reverse the direction
of motion of the " traverse with the minimum of vibration, jar, or shock on
the framing due to inertia of parts, so that the roll may be built to hold together
when removed from the spindle, and that it may be of the correct shape.
And in order that our said invention and the manner of performing or carry-
ing the same into effect or practice may be properly understood, we have here-
unto appended five explanatory sheets of drawings in which the same reference
numerals are used to indicate corresponding parts in all the figures where
shown, that is to say:-
Figure 1 (Sheet 1) is a part sectional end elevation of a winding machine
showing the reversing gear.
Figure 2 (Sheet 1) is a plan.
Figure 3 (Sheet 2) is a front elevation of same and Figure 4 (Sheet 2) is a
side elevation of a compound lever.
Figure 5 (Sheet 3) is an end elevation showing a modified form of reversing
gear for a winding machine.
Figure 6 (Sheet 3) is a plan of same and Figure 7 (Sheet 3) is a section at A A
(Figure 6) showing one of the fixed guides.
Figure 8 (Sheet 4) is an end elevation of a winding machine showing yet
another modification of the reversing gear.
Figure 9 (Sheet 4) is a plan and Figure 10 (Sheet 5) is a front elevation of
same.
In carrying out our invention according to one modification, as illustrated by
Figures 123 and 4, we cause two wheels 11--which are preferably of heavy rim
section so that they may act as fly wlieels-to rotate in opposite directions and at
a uniform speed about a common axis. These wheels are driven by a pinion
wheel 12 which in turn is driven by a belt and pulleys 13 and 14. These two
wheels are placed close to one another, but with a space between them. In this
space are two compound levers 15 placed opposite one another.
Each com-
pound lever oscillates in a plane normal to the axis of the wheels, while in
addition their supplementary levers 16 oscillate in a direction at right angles
to same, that is to say the compound lever as a whole oscillates in one plane
while the supplementary lever in addition oscillates in another. The sides of
the wheels next the compound levers are provided with hardened steel stops 17
so placed relative to each other that such compound levers are Alternately
actuated by the one wheel and the other. To facilitate the engaging of each
supplementary lever with each wheel in succession, they are so hinged or jointed
at 18 that they may be made to incline towards the one or the other wheel, such
inclination being brought about by suitable stationary inclined guides 19 near the
periphery of the wheels. Each of these supplementary engaging levers oscillates
from side to side towards the one wheel or the other by means of these inclined
guides, their final and extreme position when engaged with a wheel being deter-
mined by means of pointed spring push knobs 20 one of which is on each main
lever. 41 are rings against which the levers 16 slide. Each compound lever
forms part of or is mounted upon a duplex sleeve 21 upon which each of the
aforesaid wheels rotates, its other extremity having upon it a lever 22 to which
the traverse rods 23 are coupled. A similar compound lever and its appur-
tenances is placed opposite as has already been pointed out, the two sets being
so arranged as to be in equilibrium when in action. Each wheel 11 is loose on
its sleeve, the two sleeves being free to rotate separately.
When working, their action is such that the uniform rotation of the two
wheels 11 in opposite directions by means of the balanced mechanism described,
consisting of the levers 22 and their appurtenances, causes the traverse rods 23

page_text: to reciprocate at such a rate as to build suitable rolls of twine or thread with
the minimum vibration or shock to the frame of the machine.
In another modification; as'illustrated by Figures 5 6 and 7 we may cause the two
wheels 24 to rotate in the same direction at a uniform rate about a common axis.
Each compound lever 25 is pivoted on an axis 26 normal to the axis about which
the wheels rotate, its supplementary lever 27 being pivoted in such a manner
that it can oscillate at right angles to the main lever while at the same time it
oscillates along with it. On the periphery of each wheel are hardened steel
stops 28 with which each extremity of the supplementary lever 27 engages in
turn. Fixed inclines 29 cause the one extremity or the other of such supple-
mentary lever to approach within a certain distance of one or the other wheel 24
after which a pointed spring push knob 20 acting on a projection 30 on the lever
causes it to fully engage with one or the other wheel and so makes the main
lever 25 to oscillate and the "traverse" to reciprocate. The duplex levers are
balanced for the purpose previously described:
In a third modification, we cause a cylinder or drum 31 to rotate at a uniform
speed. On its cylindrical surface is an endless groove 32 or its equivalent, so
arranged that it makes the extremity of a lever 33, which is in contact with it,
to oscillate from side to side at a uniform rate, the axis of such lever being at
right angles to the axis of the cylinder. Projecting on each side of the aforesaid
oscillating lever 33 and moving in unison with it, are two other levers 34 to
whose extremities are coupled connecting rods 35, their other extremities moving
in guides 36. Hardened steel projections 37 on such connecting rods engage
with similar steel stops on the periphery of steel collars 38 fixed on the cam
cylinder shaft, that is to say each rod alternately is pushed by the correspond-
ing projection on its collar. A similar set of levers are actuated by the cylinder
at the opposite side, in this manner balancing the forces tending to cause vibra-
tion in the machine. Other levers 39 may be fixed on the arbors of the oscil-
lating levers, and to these the connecting rods 40 for actuating the traverse
gear 23 may be attached.
The rate at which the levers 33 34 oscillate, and the projections on the
collars 38 rotate, may or should be nearly uniform, that is to say the diameter
of the cylinder where the endless groove is may be larger than the portions
where the projections are.
The action of the combination is as follows:-
The cylinder 31 as it rotates causes the levers 33 to oscillate by means of the
endless groove 32. The oscillation of such levers, by means of the usual
mechanism, would cause the traverse gear to reciprocate, but in time the groove
would wear at certain points and so set up undue vibration in the machine. The
supplementary mechanism, consisting of the connecting rods 35 and the stops
on the collars are so arranged that they give the needful push to the oscillating
lever at the critical moment and thus reduce the wear and tear on the cam,
thereby building a more perfect roll.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
(1) In machines for winding yarn, twine or thread into rolls, the combination
and arrangement of parts for actuating and instantaneously reversing the
traverse," substantially as described and illustrated by Figures 123 and 4 of
the annexed drawings.
