OF SPOT YARNS, AND IN THE APPARATUS EMPLOYED THEREIN."
PROVISIONAL SPECIFICATION left by the said Gustavus Adolphus John
Schott at the Office of the Commissioners of Patents on the 6th April 1880.

"IMPROVEMENTS IN THE MANUFACTURE OF SPOT YARNS, AND IN THE APPARATUS
EMPLOYED THEREIN."
This Invention has for its object improvements in the manufacture of spot yarns,
and in the apparatus employed therein.
The first part of such Invention relates to the production of a compound yarn or
thread composed of two or more continuous yarns, and a number of short detached
pieces of soft thread slubbing or roving, so twisted together that round one or
more of the continuous yarns or threads forming the "ground" or core of the
combined yarn are twisted one or more of the continuous yarns or threads
hereafter termed the "carrier," in such a manner, that at certain intervals, the
lengths of which can be regulated as required, they form knobs or protuberances
nearly globular or spherical in form upon the core or ground yarn. The novel
feature in this part of the Invention consists in such knobs or protuberances not
being formed by the carrier alone, but also by the before mentioned detached
pieces of soft thread slubbing or roving, hereafter termed the "float," one or more
of which, conjoined with the carrier at the moment of forming a knob, are twisted
up with the carrier into such knob. When the knob is formed the connection
between the "carrier" and the "float" temporarily ceases, whilst the carrier alone
is twisted up with the ground, thus forming the interval between two knobs, but
the connection between carrier and float is again resumed on the formation of the
next knob, and again severed in the succeeding interval, and so on continuously
until the operation is finished. By these means a variety of new and useful effects
can be produced not hitherto attainable in spot yarns, owing to the color of the
knob being of necessity continued through the intervals or spaces also, and the spot
thread being thereby visible and traceable in its full length through the cloth,
thereby giving a stripe effect to the cloth if used as warp or weft only, or a check

page_text: effect if used both as warp and weft, which is objectionable in cases where neither
a stripe nor a check effect is desired. Another advantage of this improved method
of manufacture is that woollen yarns may be used for the "ground" and "carrier,"
and silk for the "float." Thus, when this compound yarn is woven into a woollen
cloth a clear and distinct silk effect is obtained in the form of silken spots upon a
woollen ground work containing no silk, an effect hitherto unattainable, as
heretofore in spot yarns made with a woollen ground and silk spot the silken
thread forming the latter was continued through the intervals between the spots,
and was therefore visible in its entire length through the cloth. This nonly
changed the effect but increased the cost, as the silk used in the intervals or spaces
of the old spot yarn is economised by the present Invention. I would here observe
that the connection between the carrier and the float need not necessarily be
restored at each succeeding knob, but alternately or at every third or fourth knob,
as may be desired, and the intervening knobs may be formed by the "carrier
solely.
"
In this manner, aided by suitable variations in the colours of the “ground,”
"carrier," and "float". of the combined yarn, a further great variety of new effects can
be produced and transferred to the goods into which these yarns are manufactured.
The ground or core, the carrier and the float of the combined yarn may consist
of wool, cotton, silk, or other fibrous material, or of a combination of different
fibrous materials, but in order to allow of the float being readily severed between
the carrier and float rollers, as hereafter described, the fibre of which the float is
composed should not be longer than the distance between the points of contact of
the respective bottom and top rollers of such carrier and float rollers, the float
thread or threads should also be so soft, that is, either without twist or with only so
little twist that they can readily be drawn out and severed between tho revolving
carrier rollers and standing float rollers.
The second part of this Invention relates to improvements in the apparatus
employed in the manufacture of such improved spot yarns, which may be produced
either upon spinning or twisting machinery adapted to the purpose in the following
manner:-
Instead of the delivery and spinning rollers of an ordinary spinning frame or the
delivery rollers of an ordinary twisting frame, I mount upon the frame three sets of
delivery rollers of any suitable dimensions, each set consisting of bottom and top
rollers of suitable diameter, so arranged that the front pair of rollers which deliver
the carrier and float to the ground yarn, and which aro hereafter termed the
"carrier rollers," are placed where the rollers which deliver the yarn to the
spindles on ordinary spinning or twisting frames are usually mounted. Close
behind the "carrier" rollers, and on the same level, is mounted another similar
pair of rollers, hereafter terined the "float" rollers, of about the same diameter as the
carrier rollers, and which are used for delivering the float to the carrier-rollers.
Behind or above such float-rollers, on a level higher by a few inches, I mount the
third pair of rollers used for the delivery of the ground yarn, and called the "ground
rollers." The top rollers of the carrier and float rollers are pressed on to their
respective bottom rollers by means of weights or springs in the ordinary manner,
but the top rollers of the ground rollers need not be weighted, nor are the diameters
of the ground rollers material. The carrier rollers are made to revolve by being
connected with the main driving shaft of the frame by toothed wheels or other
ordinary gearing in such a manner, that their speed can be varied as desired by
means of change wheels, and their notion continues as long as the frame is in
motion, but the revolution of the ground and float rollers is intermittent, the ground
rollers being in motion whilst the intervals between the knobs are being formed, as
before described, and being inactive whilst the knobs themselves are being formed.
The float rollers are only in motion when the float is required to be introduced into
a knob, and are at rest whenever this is not required. It is therefore obvious that
when the ground rollers are in motion the float rollers are at rest, and vice versa.
In order to obtain this result, I connect the float and ground rollers with the main

page_text: driving shaft of the frame in such a manner, that the connection can be interrupted
and reestablished as required. This I effect by means of a lever, at one end of
which a toothed wheel, hereafter terined the "lever wheel," is mounted upon a
pivot fixed upon the lever at a right angle with the longitudinal direction of the
lever, and parallel to a revolving rod which acts as pivot and fulcrum to the lever,
such fulcrum being placed between the power and the weight of the lever.
Fastened to this revolving lever pivot, and revolving therewith, is another toothed
wheel which gears with the before mentioned lever wheel, and so transmits the
motion of the revolving lever pivot thereto, while the other end of the lever is
ncted upon by a tappet or a wytch engine or other suitable apparatus in such a
manner that the lever wheel can be placed alternately and at will into cither of
the following three positions, that is to say:-
It can be thrown into contact or gearing with toothed wheels in connection with
and capable of transmitting the motion of the lever wheel to the ground rollers.
Or it can be thrown into contact or gearing with other toothed wheels in connection
with and capable of transmitting the motion of the lever wheel to the float rollers.
Or such lever wheel can be placed midway between the toothed wheel gearings in
connection with the ground rollers and float rollers rospectively, in such a manner
as not to be in contact or gearing with either of them. Whilst in either of these
three positions, the lever is held in position by means of springs of sufficient
strength to overcome the resistance of the ground or float rollers, turned by means
of the lever wheel.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed

"IMPROVEMENTS IN THE MANUFACTURE OF SPOT YARNS, AND IN THE APPARATUS
EMPLOYED THEREIN.”
"
This Invention has for its object improvements in the manufacture of spot yarns,
and in the apparatus employed therein.
The first part of such Invention relates to the production of a compound yarn or
thread composed of two or more continuous yarns, and a number of short detached
pieces of soft thread slubbing or roving, so twisted together that round one or
more of the continuous yarns or threads forming the ground or core of the
combined yarn are twisted one or more of the continuous yarns or threads,
hereafter termed the "carrier," in such a manner that at certain intervals, the
lengths of which can be regulated as required, they form knobs or protuberances
nearly globular or spheroidal in form upon the core or ground yarn. This effect,
apart from the introduction of the detached pieces of .soft thread slubbing or
roving into the knobs, as hereinafter described, is not new, but belongs to the class
of yarns well known under various names, such as spot yarn and knopped yarn.
The novel feature of this part of the Invention consists in such knobs or pro-
tuberances not being formed by the carrier alone, but also by the beforementioned
detached pieces of soft thread slubbing or roving, which are hereafter termed the
float," one or more of which, conjoined with the carrier, at the moment of
forming a knob are twisted up with the "carrier" into such knob. When the
knob is formed the connection between the "carrier" and the "float" temporarily
ceases, whilst the carrier alone is twisted up, with the ground thus forming the
interval between two knobs, but the connection between carrier and Bloat is again
resumed on the formation of the next knob, and again severed in the succeeding
interval, and so on continuously until the operation is finished. By these means a
variety of new and useful effects can be produced. If, for example, I employ a
ground and carrier of black color and a float of scarlet color, it will be evident
that the scarlet color will appear in the knobs only, whilst the intervals or spaces
between the knobs will be black. On the combined yarn being introduced into a
black cloth the scarlet color in the knobs will appear as distinct and clear scarlet
specks upon a uniformly black surface. If the knobs are made of globular form
nearly the same effect will be produced, whether the compound yarn be woven
into the cloth as warp or as weft, which gives a valuable alternative in cases
where it might be difficult to use it as warp (for example, the reed desired to be
used may be too fine to admit of the knobs of the compound yarn passing through
it), but easy to use it as weft, or vice versa. These effects cannot be obtained
with the old spot yarn, owing to the color of the knob upon it being of necessity
continued through the intervals or spaces also, and the spotted thread being
thereby visible and traceable in its full length through the cloth, thereby giving a
stripe effect to the cloth if used as warp or weft only, or a check effect if used
both as warp and weft, which is objectionable in cases where neither a stripe or a
check effect is desired. Another advantage of this improved method of manu-
facture is that woollen yarns may be used for the ground and carrier and silk for
the float. Thus when this compound yarn is woven into a woollen cloth a clear
and distinct silk effect is obtained in the form of silken spots upon a woollen
ground work containing no silk, an effect hitherto unattainable, as heretofore in
spot yarns made with a woollen ground and a silk spot the silken thread forming
the latter was continued through the intervals between the spots, and was there-

page_text: fore visible in its entire length through the cloth. This not only changed the
effect, but also increased the cost, as the silk used in the intervals or spaces of the
old spot yarn is economised by the present Invention.
I would here observe that the connection between the carrier and the float need
not necessarily be restored at each succeeding knob, but alternately or at every
third or fourth knob as may be desired, and the intervening knobs may be formed
by the carrier solely, or it can be introduced into two or more successivo knobs,
leaving the next one or more knobs to be formed by the carrier solely. In this
manner, aided by suitablo variations in the colors of the ground carrier and float
of the combined yarn, a further great variety of new offects can be produced and
transferred to the goods into which those yarns are manufactured. The ground or
core, the carrier, and the float of the combined yarn may consist of wool, cotton,
silk, or other fibrous material, or of a combination of different fibrous materials,
but in order to allow of the float being readily severed between the carrier and
float rollers, as heroafter described, the fibre of which the float is composed should
not be longer than the distance between the points of contact of the respective
bottom and top rollers of such carrier and float rollers, while the float thread or
threads should also be so soft, that is, either without twist or with only so little
twist that they can readily be drawn out and severed between the revolving
carrier rollers and standing float rollers. I would here remark that if the fibre of
the float material is longer than the distance between the said respective points of
contact of the carrier and float bottom and top rollers, the float cannot readily be
broken or severed between the carrier and float rollers.
The second part of this Invention relates to improvements in the apparatus
employed in the manufacture of such improved spot yarn, which may be produced
either upon spinning or twisting machinery adapted to the purpose in the following
manner:
Instead of the delivery and spinning rollers of an ordinary spinning frame or the
delivery rollers of an ordinary twisting frame, I mount upon the frame three sets
of delivery rollers of any suitable dimensions, each set consisting of bottom and top
rollers of, say, or 1" diameter, so arranged that the front pair of rollers which
deliver the carrier and float to the ground yarn, and which are hereafter termed
the "carrier rollers" are placed where the rollers which deliver the yarn to the
spindles on ordinary spinning or twisting frames are usually mounted. Close
behind these "carrier "rollers, and on the same level, is mounted another similar
pair of rollers (bereafter termed the "float" rollers") of about the same diameter as
the carrier rollers, and which are used for delivering the float to the carrier rollers.
Behind and above such float rollers on a level, higher by a few inches, I mount
the third pair of rollers used for the delivery of the ground yarn and called the
'ground rollers." The top rollers of the carrier and float rollers are pressed onto
their respective bottom rollers by means of weights or springs in the ordinary
manner, but the top rollers of the ground rollers need not be weighted, nor are the
diameters of the ground rollers material. The carrier rollers are made to revolve
by being connected with the main driving shaft of the frame by toothed wheels or
other ordinary gearing, in such a manner that their speed can be varied as desired
by means of change wheels, and their motion continues as long as the frame is in
motion, but the revolution of the ground and float rollers is not continuous with
the motion of the frame generally, but is intermittent; the ground rollers being in
motion whilst the intervals between the knobs of the combined yarn are being
formed, as before described, and being inactive whilst the knobs themselves are
being formed. The float rollers are only in motion when the float is required to be
introduced into a knob, and are at rest whenever this is not required. It is there-
fore obvious that when the ground rollers are in motion the float rollers are at
rest, and vice versd. In order to obtain this result I connect the float and ground
rollers with the main driving shaft of the frame in such a manner that the con-
nection can be interrupted and reestablished as required. This I effect by means
of a lever at one end of which a toothed wheel, hereafter termed the "lever wheel,”

page_text: '
is mounted upon a pivot fixed upon the lever at a right angle with the longitudinal
direction of the lever, and parallel to a rod or stud which acts as pivot and fulcrum
to the lever, such fulcrum being placed between the power and the weight of the
lever. Upon this lever pivot is also mounted another toothed wheel which gears
with the before mentioned lever which, either directly or by means of one or more
intermediate wheels fixed to the lever, and so transmits to the said lever wheel the
motion of the main driving shaft of the frame with which it is connected by
ordinary gearing.
The other end of the lever is acted upon by a tappet or a wytch engine, or other
suitable apparatus, in such a manner that the lever wheel can be placed alternately
and at will into either of the following three positions, that is to say, it can bo
thrown into contact or gearing with a toothed wheel in connection with and
capable of transmitting the motion of the lever wheel to the ground rollers; this
position I will call the A position of the lever and lever wheel. Or it can be
thrown into contact or gearing with another toothed wheel in connection with and
capable of transmitting the motion of the lever wheel to the float rollers; this
position I call the B position. Or such lever wheel can be placed midway between
the toothed wheel gearings in connection with the ground rollers and float rollers
respectively, in such a manner as not to be in contact or gearing with either of
them; this position I call the C position. The lever is assisted in keeping its
position firmly by springs or weights sufficient to overcome the resistance of the
ground rollers turned by means of the lever wheel.
Having now described the main mechanical arrangements of my improved
apparatus, I will proceed to describe the process of the ground carrier and float
being twisted up into the compound yarn in passing through it. Let us suppose
that the ground carrier and float threads are properly guided to and passed between
their respective rollers on to the spindle in the ordinary manner; the ground yarn
on its way from its rollers to the spindle is made to pass close in front of the
carrier rollers, whereon being twisted it will be joined by the carrier or carrier and
float issuing from the carrier rollers. Let the speed of the carrier and ground
rollers be so arranged as to deliver about the same length of yarn when both are
in motion, and the lever and lever wheel to be in the A position, that is, in gear
with the ground rollers. On the frame being set in motion the carrier and ground
rollers will deliver their respective yarns which by the revolution of the spindles
will be twisted or folded spirally round each other in the ordinary manner, but as
the float rollers are standing the float consisting of soft thread slubbing or roving
either without twist, or so softly twisted as to be readily drawn out and severed,
as already mentioned, will be drawn out and severed between the float and carrier
rollers, which are arranged in such a manner that the length of float held between
them is not less than the average length of the fibres of which the float is formed
as before indicated; no float will therefore be delivered to the compound yarn
by the float rollers whilst they are standing. If now the lever and lever wheel
by the action of the tappet or wytch engine is placed into the C position,
as before described, both the ground and float rollers will be at rest and
delivering no yarn, whilst the carrier rollers continue delivering their yarn,
the consequence being, as will be readily understood, that the carrier yarn will
be twisting and winding round and round that point of the stationary though
revolving ground yarn where it is met by the carrier issuing from its rollers, and
by this action a knob or protuberance is formed by the carrier upon the ground
yarn, as before described, until the lever is brought back again into the A position,
when both the ground and carrier are delivered. again by their respective rollers
and travel together towards the spindle, being spirally twisted or folded round
each other as before, and forming the interval between the last knob and the next,
which will be produced again on the lever being transferred to the C position in
the same manner as the last knob. If, however, instead of changing the position
of the lever from the A position to the C position it is changed from the A position
to. the B position, it will be clear that whilst the delivery (but not the rotation) of

page_text: the ground yarn is interrupted, both the carrier and float rollers will be in motion,
the float rollers will deliver float yarn to the carrier rollers, which will pass forward
the float yarn so delivered to them together with their own carrier yarn to the
ground yarn, and both together will be twisted or wound round the ground and
form the knob upon it, as already described. On the lever being put back again
from the B position into the A position the float rollers will be stopped, the float
yarn broken between the stationary float rollers and the revolving carrier rollers,
and the next interval formed by the ground and carrier, as before described. It
will be clear from the foregoing description that whilst the intervals are always
formed by the ground and carrier, the fact whether a knob is formed by the carrier
being alone wound upon the ground or in conjunction with the float will depend
upon the changes of the lever from the A position to the C position or from the
A position to the B position respectively. When the lever is changed from the A
position to the C position the knob will be formed by the carrier alone; when
changed from the A position to the B position it will be formed by the carrier and
float combined, being twisted or wound upon the ground yarn. To effect the more
complicated series of changes of the lever positions it will be preferable to employ
the wytch engine rather than tappets for acting upon the lever, as a greater variety
of changes can by this means be more easily obtained. The wytch engine is made
to act upon the lever on the same principle and in a similar manner (the precise
arrangements of which will offer no difficulties to practical men) as it acts in causing
the circular boxes of a loom to turn by means of a card and lever arrangement.
By these means the changes of the lever from the A position to the B or C position,
as before described, can be effected in any desired variety.
And in order that my said Invention may be better understood and readily
carried into effect, I will now proceed to describe the accompanying Drawings.
DESCRIPTION OF THE DRAWINGS.
In Figure 1 the improved apparatus is shewn as applied to an ordinary woollen
twisting frame. Z is the main driving shaft of the frame U, the tin roller turning
the spindles by means of bands; W, pulley fixed upon Z, and driving by means
of a belt another pulley T which is mounted upon a socket, together with toothed
wheel S. The motion is transmitted, as clearly shewn in the Drawing, by means
of the toothed wheels Q, R, P, and O, to the toothed wheels N and H. The
wheel H turns upon the stud G, which also acts as pivot and fulcrum to the
lever F. Upon a stud fastened to one end of the lever F is mounted the toothed
wheel E, called the lever wheel, to which the motion of wheel H is transmitted by
means of an intermediate wbeel, as shewn in the Drawing. Mounted upon one
socket with the wheel N, and revolving therewith, is the tappet M, which acts upon
a stud fastened to the other end of lever F, and causes the lever E to move and
pivot upon the stud G in a vortical direction in accordance with the changes of
level of the circumference of the tappet M. The circumference or outer rim of the
tappet M is in the form of sections or portions of the arcs of three circles of
different diameters, but having the centre of M for their centre; these circles are so
devised that when the sections in the line of the arc of the largest or outermost
circle act upon the lever F (as shewn in the Drawing, and termed the B position),
the revolving lever wheel E is depressed until it is in contact or gearing with the
toothed wheel I fastened upon the end of roller B, which is the botton roller of the
float pair of rollers, and the float rollers are consequently put in motion. At the
same time the "carrier rollers" C and C¹ are also in motion, as they revolve con-
tinuously by being connected with the main driving shaft Z by toothed wheels or other
ordinary gearing, not shown in the Drawing. Float thread is therefore delivered
by the float rollers B and B¹ to the carrier rollers C and C', and passed between
them together with the carrier yarn, to the point of junction with the ground
yarn in front of the carrier rollers, but as the ground yarn is not passing
onwards towards the spindle D on account of the ground rollers A and A¹

page_text: This is
being at rest, and therefore not delivering the ground yarn, the carrier and
float yarn is wound round the ground yarn revolving in unison with the
bobbin L mounted upon the spindle D and forming a knob or spot upon the ground
yarn. When, by the revolution of the tappet M, the section in the line of the arc
of the second or middle circle passes under the stud of the lever F the said lever
is pressed down by the weight X upon the rim of the tappet M, and the lever
wheel E riscs out of contact with the wheel I, the float rollers being consequently
stopped into the space between wheels 1 and K and so as not to be in contact with
either of tho two wheels I and K. This is termed the C position of the lever
wheel E, and at this stage both the float and ground rollers are standing, and
only the carrier rollers C and C revolving and delivering carrier yarn, which is
alone wound upon the ground yarn. When finally, by the continued revolution of
the tappet M, the section of its circumference in the line of the are of the smallest
or innermost circle comes to act upon the lever F, the lever wheel E rises into
contact or gearing with the wheel K fastened upon the end of the roller A, which
is the bottom roller of the ground pair of rollers; the ground rollers are therefore
set in motion delivering ground yarn, which, passing forward in front of the
carrier rollers C, and C', is there met by the carrier yarn, and the two, whilst being by
the revolution of the spindle D twisted spirally round each other, pass forward to
the spindle D and are wound upon the bobbin L in the ordinary manner.
termed the A position of the lever wheel E. The result of the process so far
described has been the formation of a knob consisting of carrier and float yarn, and
of a space consisting of carrier and ground yarn; it has been effected by a quarter
revolution of the tappet M and will be regularly repeated four times with every
revolution of the tappet M, as shewn in the Drawing. But it will be obvious that
as the order in which the A, B, and C positions of the lever wheel E follow each
other is determined by the shape of the tappet M, variations in that order
and their consequent results in the compound yarn can be attained by
using a tappet of a different shape. If, for example, instead of the sequence
of the B, C, and A positions, as described in the foregoing, being regularly
repeated four times round the tappet M, as shewn in the Drawing, two opposite
protuberances or sections into the line of the arc of the largest or outermost circle
were removed from the rim or circumference of the tappet N, the regularly
repeated sequence of the B, C, and A positions as described would be changed into
the following succession of the positions of the lever wheel E-B, C, A; C, A;
B, C, A; C, A, and so forth, and the result would be that the float yarn would be
introduced into every alternate knob only, the intervening knobs being formed by
the carrier solely. In this manner by varying the form of the tappet a variety of
effects can be attained, but a still larger variety is possible by substituting for the
tappet a wytch or dobby engine for working the lever F by means of a card and
lever arrangement, in a manner similar to the one adopted in the working of the
circular boxes of a loom by means of the wytch or dobby engine.
Figure 2 is a section of the carrier float and ground rollers intended to shew
more clearly than is done in Figure 1 the course of tho ground, carrier, and float
yarns. A and A' are the ground rollers; B and B¹, the float rollers; C and C¹, the
carrier rollers.
The ground yarn passes between A and A' by the side of C' and over C to the
spindle.
The carrier yarn passes over B¹ between C and C¹ to its point of junction with
the ground yarn in front of C and C¹.
The float yarn passes between B and B¹ and between C and C¹ to the
aforesaid point of junction of the ground and carrier yarns in front of C and C¹.
The direction of motion of the rollers, wheels, pulleys, and other parts is
indicated by the arrows.
Having thus described the nature of my said Invention of "Improvements in
the Manufacture of Spot Yarns, and in the Apparatus employed therein," and the
manner of carrying the same into effect I would have it understood that I do not

page_text: contine myself to the precise mechanical details herein before specified as the same
may be varied without departing from the primary feature of my Invention, which is
producing a "spot" yarn having globular or nearly globular or spheroidal knots or
protuberances thereon at certain regulated intervals.
What I claim as my Invention is,―
1°. The manufacture of an improved "spot" yarn composed of two or more
continuous yarns and a number of short detached pieces of soft thread slubbing or
roving, so twisted together that at certain regulated intervals globular or nearly
globular or spheroidal knobs, knots, or protuberances are produced, all or some of
which contain either a color or material, or both, not contained in the intervening
spaces between such spots, knobs, or knots.
2°. The improved combined arrangement of apparatus consisting of a triple set
of delivery rollers A, A, B, B, C, C', spindle D, lever wheel E, lever F, stud G,
wheels H, I, K, bobbin L, tappet M or its equivalent, toothed wheels N, O, P, Q,
R, S, pulley T, roller U, pulloy W, weight X, and main driving shaft Z, or any
mere modification thereof, all arranged and fitted substantially in the manner
and for the purposes hereinbefore described and illustrated.
In witness whoreof, I, the said Gustavus Adolphus John Schott, have hereunto
set my hand and seal, this Fifth day of October, in the year of our Lord
One thousand eight hundred and eighty.
