EDWARD HORSFALL, of Thornton Road, Bradford, in the County of York, Yarn
Doubler. IMPROVEMENTS IN MACHINERY OR APPARATUS EMPLOYED IN THE
MANUFACTURE OF FANCY YARNS,"
This Invention relates to improvements in machinery or apparatus for twisting or
doubling plain or fancy threads of wool, or of any other kind of fibrous material, either
single or inanifold, by which knots are formed in the yarn, and at certain distances,
by preference not less than half an inch, apart, increasing according to requirements
to any given distance, and the knots may vary in size and be either small or large
as required.
For this purpose in an ordinary twisting or doubling frame at each end I secure
brackets to which are fitted two bars or rails which extend across the framo; a
space is left between the bars or rails for the passage of the threads forming the
knots and for the threads of each spindle.
On the side of the brackets are secured horizontal supports, in the ends of which
are fitted the ends of a rod which extends across the twisting frame from end to
end, and each end of the rod is secured at an angle to levers, in the ends of which
are passed the ends of a small rod which extends across the frame. The rod receives
a lifting and lowering or rocking motion, and takes up the slack threads that form
the knots, and which are twisted round centre or foundation threads. The knot
threads are by preference soft threads or yarn, and are wound on bobbins which
are placed on the spindle of an ordinary twisting frame; the soft yarn passes from
the bobbins over a guide rod and through the twizzles and guides, and from there
between the space left between the two bars or rails, and from there is taken up
by the lifting and lowering or rocking small rod, which gives the soft yarn a lift

page_text: whilst the centre or foundation threads are being twisted; the lifting or rocking
of the small bar causes a lifting up of the soft yarn and also gives a turn over
which forms the knots; the knots are made small or large by the position of a
connecting rod secured in the top or bottom of a slot hole formed in a lever giving
more or less lifting action to the rocking rod. After the knots have been formed
the yarn passes through wire rings which are secured on the ordinary traps of a
twisting frame, the rings having sufficient openings to allow a free action to the
yarn passing to the flyers.
On the cylinder shaft of the twisting or doubling frame is secured a small pulley
over which works a strap, and which actuates a larger pulley fitted on a small
shaft working in bearings formed on a standard, which is secured to the end frame
of the twisting frame; on this small shaft is secured a spur wheel which actuates a
pinion which is fitted on a small shaft working in a bearing secured to the
standard; in the side of the pinion is secured a stud over which is passed one of
the heads of a short connecting rod, the other head being passed over a stud which
is secured in position in a slot hole of a lever which is fitted on the shaft on which
are secured the levers carrying the rocking rod, and the stud is secured in position
in the slot hole according to the lift required to be given and for the size of the
knots.
When the knots have been formed a binding thread is twisted round the yarn,
and this second twisting is given in the usual manner and on an ordinary twisting
and doubling frame.

by the said Edward Horsfall in the Great Seal Patent Office on the 31st
May 1882.
EDWARD HORSFALL, of Thornton Road, Bradford, in the County of York, Yarn
Doubler. "IMPROVEMENTS IN MACHINERY OR APPARATUS EMPLOYED IN THE
MANUFACTURE OF FANCY YARNS."
The said Invention relates to improvements in machinery or apparatus for
twisting or doubling plain or fancy threads of wool or of other kind of fibrous
material, either single or manifold, whereby knots or loops are formed in the yarn
at certain distances apart, by preference not less than half an inch, increasing
according to requirements to any given distance, and the knots or loops may vary
in size, that is to say, be made either small or large, as required.
For this purpose, in an ordinary twisting or doubling frame, and at each end
thereof, I secure brackets, to which are fitted two bars or rails which extend across
the frame; a space is left between the bars or rails for the passage of the threads
forming the knots or loops, and for the threads of each spindle.
On the sides of the brackets are secured horizontal supports, in the ends of which
are fitted the ends of a rod, which extends across the twisting frame from end to
end; and at each end of the rod are secured at an angle levers, in the ends of
which are passed the ends of a small rod which extends across the frame. The rod
receives a lifting and lowering or rocking motion, and takes up the slack thread
that forms the knots or loops, and which are twisted round centre or foundation
threads. The knot or loop threads are by preference soft threads or yarn, and are
wound on bobbins which are placed on the spindles of an ordinary twisting frame;
the soft yarn passes from the bobbins over a guide rod, and through twizzles and
guides, and from there between the space left between the two bars or rails, from
which they are taken up by the lifting and lowering or rocking small rod, which
gives the soft yarn a lift whilst the centre or foundation threads are being twisted;
the lifting or rocking of the small bar causes a lifting up of the soft yarn, and also
gives a turn over which forms the knots or loops; the knots or loops are made
Sinall or large, according to the position of a connecting rod secured in the top or
bottom of a slot hole formed in a lever, giving more or less lifting action to the
rocking rod. After the knots or loops have been formed the yarn passes through
wire rings, which are secured on the ordinary traps of a twisting or doubling
frame; the rings have sufficient openings to allow a free action to the yarn passing
to the flyers.
On the cylinder shaft of the twisting or doubling frame is secured a small pulley,
over which works a strap, which actuates a larger pulley fitted on a small shaft
working in bearings forined on a standard secured to the end frame of the twisting
frame; on this small shaft is secured a spur wheel which actuates a wheel fitted.
on a small shaft working in a bearing secured to the standard; in the side of the
wheel is secured a stud, over which is passed one of the heads of a short connecting
rod, the other head being secured in position in a slot hole of a lever fitted on the
shaft, on which are secured the levers carrying the rocking rod; the stud is secured
in position in the slot hole according to the lift required to be given, and for tho
size of the knots or loops.
When the knots or loops have been formed a binding thread is twisted round
the yarn, and this second twisting is given in the usual manner, and on an ordinary
twisting and doubling frame.
I also employ levers fitted on a rod extending across the twisting frame, and
secured at each end of the rod; in the ends of these levers is secured a wedge

page_text: ..
shaped rod extending across the frame; this wedge shaped rod receives a recipro-
cating action or rocking motion, and the rod is actuated by a lever secured to the
rod carrying the wedge shaped rod levers, and the lever receives a lowering action
by means of friction rollers coming in contact with the top edge of the lever; these
friction rollers work on studs secured to the required position in slot holes to form &
large or small knots or loops, and the slot holes are made in a wheel actuated by
another smaller wheel working on a stud secured in a bracket bolted to the frame.
The lever actuating the wedge shaped rod after having been depressed is pulled
back into position by a spiral spring secured to the lever, and to the end of a
bracket bolted to the standard. The yarn to form the knot or loop coming from 1
the bobbin and passing through the twizzles is made to pass under the wedge
shaped rod, and by the depression of the lever, and consequently of the wedge
shaped rod, causes a certain amount of unwinding or pulling out of the yarn
forming the knots or loops, and which, on the wedge shaped rod being brought
back into position by the spiral spring is immediately twisted up by the revolving 1
flyers, and the knots or loops are formed on the yarn or threads.
But in order to enable my improvements to be better understood, I will proceed
to describe the same by reference to the accompanying Drawing, in which Figure
1 represents a side view of part of the frame of an ordinary twisting or doubling
frame, shewing an outside side view of my improvements according to the first 2
arrangement herein described; Figure 2 is a front view of the same, and Figure 3,
full size view of the rocking rod and the two bars or rails through which the soft
yarn passes. Figure 4 represents a side view of part of the frame of an ordinary
twisting or doubling frame shewing a section and an outside view of my improve-
ments, according to my second modification, in which a lowering action of the 2
wedge shaped rod forms the knots or loops; Figure 5 is a front view of the same;
Figure 6 represents a full size view of the lever carrying the wedge shaped rod,
and of a section of the rod.
To an ordinary frame A. I secure brackets B, to which are fitted two bars or
rails C extending across the frame, a space D being left between the rails for the {
passage of the threads forming the knots or loops; to the brackets B are secured
other brackets E to which are secured brackets F in which is fitted a rod G
extending across the frame, and at each end of this rod are secured levers H to
which is fitted a rod or a wedge shaped rod I; this rod receives a lifting and
lowering or rocking action and takes up the slack threads J which form the knots
or loops, and which are twisted round centre or foundation threads K. The soft
threads or yarn J pass from the bobbins L, through twizzles M, and between
the space D, and from there are taken up by the rod I, and lifted whilst the
centre or foundation threads K are being twisted; the lifting of the rod I causes a
lifting up of the yarn J, which gives a turn over and which forms the knots or
loops.
The lifting and lowering action of the rod I is given by a strap. which works
over a pulley fitted on the cylinder shaft of the frame, and which strap actuates a
pulley N secured on a short shaft O, which works in a bearing P formed on a
standard Q secured to the frame A ; on the shaft O is fastened a wheel R which
actuates a wheel S fitted on a stud T secured in the standard Q; in the wheel S
is formed a slot hole U, in which is secured, according to the size of the knots or
loops to be formed, a stud on which is placed the head V of a connecting rod W
connected to a lever X having a slot hole Y, on which is passed the other head of
the connecting rod W; this slot hole also regulates the stroke of the rod I to
regulate the size of the knots or loops; the lever X is secured on the end of the
rod G and actuates the rod I; the knots and loops having been formed, the yarn
passes through wire rings Z, and after the knots or loops have been formed, a
binding thread is twisted round the yarn, and this operation is effected in the
usual manner on an ordinary twisting and doubling frame.
In Figures 4, 5, and 6, the wedge shaped rod I receives a lowering and lifting
motion and depresses the threads J instead of lifting them, causing a certain

page_text: amount of unwinding or pulling out of the yarn which forms the knots or loops.
The rod J is actuated by means of a strap working on a pulley fitted on the
cylinder shaft of the frame; the strap actuates a pulley N which works a small
shaft O and gives motion to a small wheel A', which actuates a larger wheel_B'
having two slot holes C' in which are secured studs having friction rollers D';
these rollers are secured in position according to the size to be given to the knots
or loops, and give more or less stroke, and the friction rollers act on the top of a
lever El secured on a rod G extending across the frame; on the rod G are secured
levers H to which is secured the wedge shaped rod I; the lever E¹ being depressed
causes a depressing action of the rod I, with a certain amount of unwinding or
pulling out of the yarn J, and when the depression has taken place the lever E¹
is brought up into position by the spiral spring F' secured to a pin fitted in the
end of a bracket G' secured to the standard Q; the spring is also secured on a pin
fitted in the lever E¹.
Having thus described my improvements and the best means I am acquainted
with for carrying the same into effect, I would have it understood that I do not
confine myself to the precise details shewn and described, as they may be varied
without departing from the peculiar character of the Invention, but what I do
claim is,―
The arrangement, combination, and construction of the several parts constituting
the hereinbefore described improvements, whereby knots or loops are formed in the
yarn at certain distances apart, substantially as and for the purpose herein set
forth and represented by the accompanying Drawing.
In witness whereof, I, the said Edward Horsfall, have hereto set my hand
and seal, this Twenty sixth day of May, in the year of our Lord One
thousand eight hundred and eighty two.
