We, BENJAMIN CUNNINGHAM WATES, WILLIAM PURDON VICCARS, and ARTHUR
CUNNINGHAM WATES, trading in partnership as John Whitmore & Co., of West
Bridge Street, Leicester, Worsted Spinners, do hereby declare the nature of this
invention to be as follows:-
-
This invention relates to improvements in yarns, and is specially applicable to
Botany, Cashmere or Berlin yarns of which shawls, hoods, mitts and other fancy
articles are made, and also applicable to yarn's used in upholstery, and dress goods
and other purposes. The improvements are however, also applicable to worsted,
merino, silk and cotton yarns or any other yarus or combinations of any of these.
The improvements consist in forming at desired intervals on the thread of yarn
during the process of manufacture, a series of knotted tufts or knots with extended
ends lying on one side of the thread or on each side alternately, or bars extending
or lying on each side of the thread or in any other way with a loose end or ends
found most suitable for the purpose for which the yarn is desired:
The said knotted tufts, bars or the like may be formed by hand or machinery
on the thread of yarn during the process of manufacture as before stated, and in
any way, manner or form most convenient.

We, BENJAMIN CUNNINGHAM WATES, WILLIAM PURDON VICCARS, and ARTHUR
CUNNINGHAM WATES, trading in partnership as John Whitmore & Co., of West
Bridge Street, Leicester, Worsted Spinners, 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:-
This invention relates to the production of fancy yarns and consists in forming
at desired intervals on the threads of yarn, a series of knotted tufts of various kinds.
A simple method of producing the said yarns is by taking a net or piece of netting,
produced in any of the well-known ways, and threading the outside meshes and in
071

page_text: some cases certain of the inside meshes, on rods or bars projecting from a machine,
consisting of grooved rollers suitably carried and a series of circular cutters revol-
uble one in each groove of the said rollers, the net being passed into contact with
the said cutters which sever or cut the threads of the netting in such form as to
produce the tufted yarns before mentioned, from which hoods, mitts, or other
fancy articles may be made, some of the yarns being applicable for the hosiery and
dress goods trades and other purposes.
In order that the invention will be better understood, we append hereto a draw-
ing in which,
Figure 1 is a vertical central section and Figure 2 a plan of a machine illustra-
ting a simple method of carrying out our invention.
A represents a piece of netting which may consist of threads of a single colour
or a variety of colours and of the same kind of yarn or a variety of yarns.
The said netting A is threaded on the ends B' of the projecting rods B. As
will be seen more clearly in Figure 2 the rods B converge towards their ends B¹
for facilitating the threading of the net A, the opposite ends B2 being wider apart,
thus drawing the net taut to facilitate the cutting by the cutters F.
C and D are rollers, preferably of wood faced circumferentially with leather or
any other suitable material and fixed on spindles C¹ D¹ respectively, the ends of
the latter being carried in bearings (2D2 in the vertical sides E of the frame E.
As before mentioned, the rollers C I have a series of grooves C* D* to allow the
circular cutters F to revolve therein. It will be readily understood that the rollers
C and D) may be of any suitable length and the other parts of the machine simi-
larly lengthened for the width of net it may be found desirable to usc and the
grooves and cutters arranged to suit the mesh of the said net.
As will be seen from Figure 2 the net A will cut into four threads of yarn of
one pattern and two threads of another pattern, the four threads A¹ having
tufts A approximately half the distance apart of the tufts A* on the outside
threads A2 As the net is cut into the threads A¹ A2 or the like the said threads
may be delivered on to recls or any other convenient means or receptacles
The cutters Fare carried upon the spindle G revolving in bearings E² in the
sides of the frame E. To keep the said cutters the required distance apart, they
are clamped between a series of tubes F2 driven tightly upon the spindle G, or they
may be fixed on the spindle in any other suitable way. The spindles CD¹ and
their respective rollers C D revolve in the directions shown by the arrows in
Figure 1, the spindle D' being driven by a belt passing round the pulley H
from any convenient source of power. The pulley J which is fixed on the spindle G
may also be driven by a belt from any suitable source, revolving the said spindle
at a considerably greater speed than the spindle D'. The roller C revolves by
frictional contact with the roller D) and pressure is put upon it by the screw bolts K
passing through the plates K¹ secured by bolts K2 to the sides E¹ of the frame E
The bolts K press upon the bearings C₁ and are screw threaded to engage plates L
by which the spring L' may be controlled to give the desired frictional pressure to
the roller C.
To further facilitate the threading of the net A upon the rods B, a series of the
said rods may be provided for each machine and the nets threaded upon them dur-
ing the time the machine is cutting up one piece of net, the ends B3 of the rods B
being shaped to fit into dovetail grooves B³ formed on the sides of the frame E.
With nets of great width additional rods B are provided when required.
It will be understood that we do not restrict ourselves to the herein described
mechanism for the production of our improved yarns as the same may be produced
in various ways.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what
we claim is:-
1. A varn having a series of tufts or the like substantially as specified.

page_text: 2. The production of a yarn of the kind described formed by moving a net in
the path of a series of revolving cutters whereby the threads of the net are cut
across the meshes in the manner and for the purpose specified..
