IMPROVEMENTS, IN THE MANUFACTURE OF FANCY YARNS, AND IN THE APPARATUS EMPLOYED THEREIN
Year: 1884

page_text: I, GUSTAVUS ADOLPHUS JOHN SCHOTT of West end Mills, Richmond Rd Bradford'
in the County of York do hereby declare the nature of said Invention for
"IMPROVEMENTS, IN THE MANUFACTURE OF FANCY YARNS, AND IN THE APPARATUS
EMPLOYED THEREIN to be as follows:-
This invention relates to the production of an improved fancy yarn or twist.
consisting of a plain thread or yarn of wool, silk, cotton or other suitable fibrous
material, either single or manifold and which for shortness of description is hereafter
referred to as the "ground thread" with which is twisted an additional plain.
thread or yarn of wool, silk, cotton or other suitable fibrous material either single.
or manifold (hereafter termed the "top thread") in such a manner that such top.
thread at intervals forms upon the ground thread clusters or tufts of short threads
or bristles, which stand out prominently from the combined twist, the portions of.
the combined twist between such clusters or tufts presenting the appearance of an.
ordinary spirally twisted yarn composed of the ground and. top threads. This
effect is produced by twisting the top thread, previous to combining it with the
ground thread very hard, so that it runs freely and easily into snarls or curls when.
left at liberty to do so. The top and ground threads are twisted together in an.
ordinary twisting frame specially adapted for the purpose by passing the ground.
thread through a set of delivery rollers which revolve intermittently, whilst the
top thread is passed through delivery rollers revolving continually. The two sets.
of rollers are speeded in such a manner that when both are revolving they deliver.
equal or nearly equal lengths of ground and top thread by which means the portions
of the combined twist situated between the tufts are formed.. But when the rollers.
delivering the ground thread stop, those delivering the top thread continue to
revolve, the top thread gets slack and owing to its hard twist runs into snarls or
curls, which are wrapped round the ground thread whilst it is standing and form:
thereon the beforementioned thready or bristly tufts.
In order to more firmly bind together the ground and top threads so as to prevent
the top thread from shifting or being loose upon the ground thread, an additional,
thread may be twisted or wound round the combined top and ground threads.
The combined yarn or twist may be uniform in colour or contain several colours
and when it is woven or otherwise manufactured into stuffs a novel effect is
produced.

page_text: I, GUSTAVUS ADOLPHUS JOHN SCHOTT Manufacturer, of West End Mills,
Richmond Road, Bradford, in the County of York do hereby declare the nature of
my invention for IMPROVEMENTS IN THE MANUFACTURE OF FANCY YARNS AND IN
THE APPARATUS EMPLOYED THEREIN and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This Invention consists firstly in the production of an improved fancy yarn or
twist hereinafter more particularly described, and secondly in improved apparatus
for the production thereof And in order that my said invention may be better
understood and readily carried into effect I will now with the aid of the
accompanying drawings proceed more particularly to describe and ascertain the
game.
My improved fancy twist consists of a plain thread or yarn of wool, silk, cotton
or other suitable fibrous material either single or manifold hereafter referred to as the
"ground thread
with which is twisted an additional plain thread or yarn of wool,
silk, cotton or other suitable fibrous material either single or manifold (hereafter
termed the "top thread ") in such a manner that such top thread at intervals forms
clusters or tufts of short threads or bristles upon the ground thread which tufts
stand out prominently from the combined twist as indicated in Fig 1 of the
accompanying drawings at 1, 2, 3, and in Fig 2, at 1, 2, 3, 4, the portions of the
combined twist between such clusters or tufts presenting the appearance of an
ordinary spirally twisted yarn composed of the ground and top threads. This effect
is produced by twisting the top thread previous to combining it with the ground
thread, sufficiently hard to cause it to run freely and easily into snarls or curls
when left at liberty to do so, and then in combining it with the ground thread
before its own hard twist has had time to
as if allowed to set it would not
form the tufts satisfactorily The top and ground threads are twisted together in
an ordinary spinning or twisting frame which is specially adapted to perform this
operation and in Fig 2 is shewn a sectional end view of a woollen ring twisting
frame thus specially adapted.
"set
The ground thread is guided and passed through a pair of delivery rollers b, b¹,
the former being the bottom and the latter the top roller. From these rollers it
passes between a second pair of delivery rollers a, a¹ the latter of which is furnished
with grooves d.-(see Fig 3 which shews a detail view in side elevation thereof),-
under one or both of which (according to whether the ground thread is single or
manifold) such ground thread is guided and passes, and is therefore not gripped
between the rollers a a¹. The " top thread" is passed through a guide e and
between the delivery rollers a, a¹ at a point between the grooves d and is therefore
acted upon and delivered by these rollers.
The delivery rollers bare by a special arrangement of gearing hereinafter
described caused to rotate intermittently that is to say they revolve and stop at
alternate intervals whilst the delivery rollers a, a¹ are by ordinary toothed wheel
gearing caused to revolve continuously as long as the frame is in inotion.
Both sets of delivery rollers are speeded 'in such a manner that when both are
revolving they deliver equal or nearly equal lengths both of the ground and top
thread which on issuing from the rollers a a¹ and proceeding to the spindle f. (Fig 2)
upon which is mounted the bobbin g are spirally twisted round each other thus
forming the portions of the combined twist situated between the before mentioned
tufts.
When however the rollers b, 61, that deliver the ground thread stop whilst the
rollers a and a¹ delivering the top thread-still continue to revolve; the top thread

page_text: gets slack and owing to the hardness of its twist runs into snarls or curls which
are by the action of the revolving spindle f wrapped round the ground thread thus
forming thereon the before mentioned tufts or clusters.
In order to more firmly bind together the ground and top threads so as to prevent
the top thread from shifting or being loose upon the ground thread, an additional
thread hereafter referred to as the " binding thread may be twisted or wound
round the combined top and ground threads.
"
This operation may be effected either by a second and separate twisting process
in the ordinary manner or it may be combined with the first twisting process thus
dispensing with the necessity for any further twisting process in the following
manner, which is also illustrated in Fig 2.
The "binding thread" is passed through an additional pair of delivery rollers c, cl
of which the former is the bottom and the latter the top roller and over adjustable
guide rods h, i, k, to the combined ground and top threads.
When the frame is in motion the delivery rollers c, c¹ revolve continuously being
actuated by ordinary toothed wheel gearing while the position of the guide rod k is
adjusted so as to cause the binding thread to meet the combined ground and top
threads at any suitable place according to the particular pattern of yarn required
to be produced.
To allow of such adjustment being readily effected the rod k is carried in arms x
mounted on the guide rod i which latter turns in necks y to which it is secured by
thumbscrews z. Thus when the rod i is turned say 1/20 th of a revolution the rod k
revolves round it in the arc of a circle the radius of which is described by the
arms while by moving the stand o and bracket w either backwards or forwards
such rod k is adjusted laterally to the required position.
When the delivery rollers 6 6¹ and the ground thread are at rest the top thread is
forming the tufts as before described and the binding thread forms spirally twisted
knots on the combined yarn as indicated at 5, 6, 7 Fig 2 but when all three sets of
delivery rollers are working the ground and top threads are spirally twisted round
each other and the binding thread is twisted round the two thus binding them
firmly together.
It remains to describe the manner in which intermittent rotary motion is imparted
to the delivery rollers b b' to elucidate which reference is made to the accompanying
Fig wherein a bindicate the respective bottom rollers as already mentioned.
Upon the end of the roller a is fixed a toothed driving wheel m which gears with
a toothed wheel o mounted together with another toothed wheel n upon a socket
turning on a stud The outer periphery of the wheel n is made with alternate plain
and toothed segments which latter gear with a toothed wheel p mounted on the shaft
of the bottom roller b, Thus when the roller a is revolving the toothed wheels m, o
and n are also rotated but the wheel p will only revolve as long as it is in gear
with the toothed segments of the periphery of the wheel n and will be at rest
during the passage of the plain segments thereof.
By this improved arrangement intermittent rotary motion is imparted to the
rollers 6 6¹ their alternations being varied and controlled by the proportions of the
toothed and untoothed segments on the periphery of the wheel n which may be
varied as required.
The various threads of which the compound yarn is composed may consist either
of one or different materials and may be of one or more colors.
By varying the material and color a greater variety of effects can be produced
and on the compound yarn being manufactured or worked into goods either by
weaving knitting crochetting or any other process novel and improved effects are
thereby obtained.
Having thus particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1 A new or improved fancy yarn or twist consisting of a plain thread or yarn of
wool or other suitable fibrous motonial nithou.
