We, WILLIAM GAINES BYWATER, Machine Maker, and THOMAS BELLSHAW
BEAULAND, Draughtsman, of Sweet Street Foundry, Leeds, in the County of York,
do hereby declare the nature of this invention to be as follows:-'
The object of this invention is to wind rope, twine &c. in the form of a roll,
upon a tube of wood, paper, or other suitable material, in such a manner as to.
form a regular pattern all through the roll, by reason of the material being regu-
larly crossed over itself, and laid closely side by side. The mechanism by which
this is effected is constructed as follows. A frame carries two horizontal spindles
side by side, which are placed any distance apart, to suit the size of the roll.
required, for small rolls, say four inches apart. These spindles project a sufficient
distance from the frame, for the length of the roll. One spindle is made so that
a tube of paper or other suitable material may be fixed upon it. The other spindle
has a right and left hand endless screw cut in it, which is the same length as
the roll is required to be. A socket slides freely upon the screw, also upon a
rod which parallel to the screw. The socket is fitted with a tongue which
engages in the screw, so that as the screw revolves the socket moves from end to
end of the screw. A guide is hinged by one end to the socket and the other end
is fitted with a runner and has a hole of a suitable size over and through
which the yarn passes when the roll is being wound. This end of the guide rests
upon the roll as it is being wound, and is free to rise as the roll increases in
diameter, by reason of being hinged. The screw spindle and the roll spindle are
geared together in any proportion to suit the pitch of the screw and the pitch at
which it is desirable to lay the yarn on the tube. But for example say, the spindle
shall make one revolution to two revolutions of the screw. It is evident that if
the proportion of the speeds of the spindle and the screw were exactly as one is to
two the yarn would allways be laid exactly in the same place on the roll. So it is
necessary that the spindle shall revolve a certain speed faster or slower than the exact
proportion named, say for example one and one twentieth to two to suit a certain
thickness of yarn or one and one hundredth to two to suit a finer yarn so that the laps
shall be laid closely side by side. In order to accomplish this object we use a differen-
tial wheel which by preference is loosely mounted upon the roll spindle, and is driven
by gear wheels and a worm. The gear wheels are driven by means of change
gear wheels on the end of the screw spindle, or may be driven by cone pulleys and
a belt. Thus the motion of the differential wheel decreases the speed of the roll
spindle in proportion to the thickness of yarn, or may increase it either way being
practicable.

We, WILLIAM GAINES BYWATER, Machine Maker, and THOMAS BELLSHAW
BEAULAND, Draughtsman, of Sweet Street Foundry, Leeds, in the County of York,
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:-
1722
The object of this invention is to wind rope twine &c. in the form of a roll
upon a tube of wood, paper or other suitable material, in such a manner as to
form a regular pattern all through the roll. by reason of the material being regu-
larly crossed over itself and laid closely side by side. The following is a descrip-
tion of the accompanying drawings in which, the numbers have reference to the
same parts on each drawing. Fig. 1 is a side elevation of the machine. Fig. 2
is an end elevation of the driving pulley end. Fig. 3 is a top view of the machine.
Fig. 4 is an elevation of the roll spindle end of the machine. Fig. 5 is a partial
sectional plan of the differential wheel arrangement by means of which the various
thicknesses of twine &c. may be laid closely side by side when winding a roll.
Fig. 6 is a front view of a part of the same. 7 is a horizontal spindle having
driving pulleys 8 at one end and a canted spindle 9 at the other end, this spindle 9
receives a tube on which the roll is wound, 10 is an endless screw which is driven
from spindle 7 by means of wheels (which are hereafter more particularly
described) immediately above screw 10 is a slide 11 in which a bar 12 moves freely
endways, at a point in the bar 12 is a tongue 13, the pivot end of which turns in
a socket 14 on the bar, and the tongue end is engaged in the thread of the
screw 10 at one end of the bar 12 there is hinged a thread guide 15, the free end
of which rests upon the tube on the canted spindle 9. This guide 15 is free to rise
as the roll increases in diameter, as is shewn in Fig. 3. The proper speed propor-
tion. between the spindle 7 and the screw 10 so as to lay the twine closely side by
side may be obtained by means of gear wheels, by which the spindle 7 drives the
screw 10, but it is difficult by this method to obtain the great range of and the
minute changes necessary to suit the different thicknesses of twine operated upon.
By means of the invention herein described both. these are obtained. In Figs. 5
& 616 is a wheel which is fast on spindle 7 and which engages into wheel 17
which is loosely mounted on shaft 18. The wheel 17 has on its face two projecting
keys 19 which engage into two corresponding grooves 20 in one side of a cross 21.
This cross 21 is loosely mounted upon the boss of wheel 17, but revolves with it
by reason of the keys 19 engaging in the grooves 20, at the same time, the cross 21
is free to move a certain distance in the direction of the grooves 20, the hole in
the centre of the cross being elongated for this purpose. The opposite side of the
cross 21 has also two grooves 22 which are at right angles to the other two grooves,
and into which two keys 23 engage, these keys are fixed upon a V toothed wheel 24.
The wheel 24 is loosely mounted upon an excentric 25 which is part of the shaft 18.
Thus the wheel 16 drives the V toothed wheel 24 by means of and through the
wheel 17 and cross 21 and if the excèntric 25 does not revolve with the wheel 24,
the keys move in the grooves, to compensate for the difference in the centres of
revolution of the wheels 17 and 24. The V toothed wheel 24 engages into an
internal toothed wheel 26. This wheel is loosely mounted upon the shaft 18.
The wheel 26 is also an ordinary spur wheel, the teeth of which engage into
wheel 27 which is fixed on the screw 10. Thus the spindle 7 through the gearing
described drives the screw 10. In order to give the small increase or decrease of
motion to the screw 10 which is necessary for the material being wound. A slow
7

page_text: movement is given to the excentric 25 by means of shaft 18, this causes the
V toothed wheel 24 to change its place in connection with the internal wheel 26
and by so doing it either increases or decreases the speed of the wheel 26 according
to the direction in which the excentric 25 is caused to revolve. The method of
driving the shaft 18 and excentric 25 is as follows. On spindle 7 is a V speed
cone 28 which by means of belt or cord drives a similar cone 29 on shaft 30. On
one end of shaft 30 is a wheel 31 Fig. 1 which gears into wheels 32 and these again
into wheel 33 which is on the end of shaft 18, or this may be effected by means of
worm and worm wheel from shatt 30. In machines in which a cam is used
instead of a screw 10 this differential wheel arrangement may be fixed direct on
the cam shaft which will occupy the same position as the screw 10, in which case
the wheel 26 is only an internal wheel and does not need to be also a spur wheel,
and the cam may be fixed to the said wheel 26.
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. A differential wheel arrangement for the purpose as herein named and con-
structed substantially as herein set forth and described.
2. A differential wheel arrangement which is actuated by variable speed cones
or other similar devices substantially as herein set forth and described.
