PROVISIONAL SPECIFICATION.
A New or Improved Machine for Curling Yarn.
I, JAMES JORDAN, of Mold Green, Huddersfield, Yorkshire, Manufacturer, do
hereby declare the nature of this invention to be as follows:-
yarn
My invention has reference to a new form of apparatus for curling yarn, or
making it into a spiral or corkscrew form, which yarn is used in the manufacture
of astracan or other like fabrics. Hitherto the twisting of yarn for this purpose
has been effected by manual labour, but the curls or spiral twists of the have
been irregular in size, consequently the pattern of the astracan was also irregular.
To form the curls of the spirally twisted yarn in a regular and uniform manner by
mechanical and self acting means is the object of my invention, and this I
accomplish by suitably mounting any convenient number of wharles driven from a
tin cylinder, or by other suitable means. Into each wharle I place one end of a
long spindle or rod, which may either be vertical or horizontal. These spindles or
rods are driven at a suitable speed by the wharles, and as they revolve, the yarn
(coming from bobbins on a creel) is wound upon the said rods in a spiral manner,
such said yarn being guided thereon by guide eyes connected to a rising or falling
bar or rod, the arrangement being such that as the spindles revolve, such yarn is
wound upon them from one end to the other. When the rods are thus filled, they
are removed with the yarn upon them, and subjected to a process of boiling and
drying, whereby the curl in the yarn is "set." The spindles are afterwards
removed to a simple form of machine, from which the curled yarn is unwound onto
a creel ready for the subsequent operations of manufacture. The wharles carrying
the long spindles or rods are driven at suitable speeds, which may be varied by
cone pulleys or other convenient forms of mechanism; and after the yarn has been
wound from one end of the revolving rods to the other, the rotary motion of the
machine may be reversed by an arrangement of wheels operated by hand lever, so
that the yarn may be wound upon the rods back to the opposite end.
By the mechanism herein described, large quantities of yarn can be curled or
spirally twisted in a regular and uniform manner; and the sizes of the curls can
be varied by using rods of different thicknesses.

COMPLETE SPECIFICATION.
A New or Improved Machine for Curling Yarn.
1, JAMES JORDAN, of Mold Green, Huddersfield, Yorkshire, Manufacturer,
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:-
My invention has reference to a new form of apparatus for curling yarn, or
making it into a spiral or corkscrew form, which yarn is used in the manufacture
of astracan or other like fabrics.
"
Hitherto the twisting of yarn for this purpose has been effected by twisting a
number of threads together so as to cause them to "knobble into a curl of
irregular size. To form the curls of the spirally twisted yarn in a regular and
uniform manner by mechanical and self-acting means is the object of my invention ;
and this I accomplish by suitably mounting any convenient number of wharles
driven from a tin cylinder, or by other suitable means. Into each wharle I place
71

page_text: one end of a long spindle or rod, which may either be vertical or horizontal.
These spindles or rods are driven at a suitable speed by the wharles, and as they
revolve, the yarn (coming from bobbins on a creel) is wound upon the said rods in a
spiral manner, such said yarn being guided thereon by guide eyes connected to a
rising or falling bar or rod, the arrangement being such that as the spindles revolve,
such yarn is wound upon them from one end to the other. The wharles carrying
the long spindles or fods are driven at suitable speeds, which may be varied by
cone pulleys or other convenient forms of mechanism; and after the yarn has been
wound from one end of the revolving rods to the other, the rotary motion of
certain parts of the machine may be reversed by an arrangement of wheels
operated by hand lever, so that the yarn may be wound upon the rods back to the
opposite end.
Such being the nature and object of my invention, I will now proceed to describe
the same more fully, and for that purpose make reference to the annexed sheet of
drawings illustrative thereof, wherein
Fig. 1 is end elevation of a machine constructed according to my invention;
Fig. 2 is cross-section of same, and
Fig. 3 front view.
A represents the framework of the machine, having a cross rail B to which are
attached brackets C provided with a vertical stud D (see detail Fig. 4). There
may be any number of these brackets and studs, onto each of which I mount a
wharle E driven by cord F from tin cylinder G, which latter receives its rotary
motion by strap from any convenient source. In the top of each wharle there is an
opening to receive the peg or foot a of the vertical spindles H, such spindles being
supported at their upper ends by brackets or hold-fasts I attached to the top rail J
of the machine. The yarn to be wound upon these vertical revolving spindles is
represented at J, and it issues from bobbins mounted in a creel; the said yarn, on
its way to the spindles, passing under and over guide rods K, through guide eyes L
attached to the fixed rail M, and over the reciprocating rail N, carrying guide
eyes O, whereby the said yarn is conducted to and wound upon the said spindles,
and in order to traverse the yarn so as to wind it in a spiral manner upon each
spindle, the rail N is made to reciprocate or to ascend and descend at a suitable
speed whilst the spindles are revolving, and this is effected by means of the rim
wheel P, driven from cone pulleys Q by the train of gearing R, S, T, from the tin
cylinder G. The rim wheel P drives the horizontal shaft U carrying chain
wheels V around which the chain W passes, one end of such said chain being
attached to the rising and falling rail N, whilst the other end of said chain carries
a weight X to counterbalance the parts, the arrangement being such that when the
spindles are filled with the yarn wound spirally upon them, the machine is stopped
by the attendant, and the spindles removed to be replaced by empty ones, when the
operation of winding can be repeated. If necessary, however, instead of the
spindles being removed when yarn has been wound from the bottom to the top of
the spindles, the rotary motion of the rim wheel P may be reversed so as to cause
the moving rail N to descend for the purpose of winding the yarn from top to
bottom, this reversing motion being effected by the workman placing the hand
lever Y into another notch in the plate Z; the effect of which is to remove pinion S
out of gear with the driving wheel R and put pinion T into gear with the said
driving wheel R.
Fig. 4 is an enlarged section of the wharle E and parts connected therewith;
Fig. 5 is plan view thereof, and Fig. 6 is an illustration of the curled yarn. The
speed at which the rail N rises and falls can be regulated by the cone Q on the
end of the driving wheel R, whilst the speed of the spindles is governed by the tin
cylinder, which can also be regulated at will. When the rods or spindles G have
been filled with the yarn, they are removed from the machine and subjected to a
process of boiling and drying so as to fix or "set" the curl in the yarn. The
spindles are afterwards removed to a simple form of machine, from which the curled
yaru is unwound onto a reel ready for the subsequent operations of manufacture.

page_text: By the mechanism herein described, large quantities of yarn can be curled or
spirally twisted in a regular and uniform manner, and the sizes of the curls can be
varied by using rods of different thicknesses.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
Firstly. The manufacture of curled yarn by winding it on revolving spindles in
the manner substantially as shewn and described herein.
Secondly. The manufacture of curled yarn by winding it on revolving spindles,
together with means for traversing the yarn whilst being wound upon the spindles
in the manner substantially as herein shewn and described.
Thirdly. In machines for winding yarn upon spindles for the purpose of producing
curled yarn, the combination therewith of revolving spindles, guide eyes, traversing
bars, and means for reversing the guide rail N, all arranged and operated in the
manner described and shewn in the drawings.
