Improvements in the Spinning and Twisting of Fancy Yarns, and in
Machinery or Apparatus therefor.
We WILLIAM ERNEST BARFOOT and SYDNEY CHARLES HOBSON of the Firm
of T. W. Rust & Co. of St. Nicholas Square, Leicester, Spinners, do hereby
declare the nature of this invention to be as follows:-
This invention relates to the spinning and twisting of fancy yarns and consists
essentially of an improvement upon the spinning and twisting of that class of fancy
yarns in which a random or portion of a coloured thread is incorporated with
the roving or rovings in the process of spinning and twisting.
CC
"
Heretofore, as far as we are aware, it has been considered not practicable to
incorporate more than one coloured "random" during the spinning and twisting of
the yarn, but after a series of experiments we have devised means by which two or
more "randoms" of different colours may be combined in one thread or yarn during
the spinning and twisting thereof.
In carrying out our invention the ordinary roving thread passes between the back
rollers, thence to the carrier rollers and front rollers and finally to the flyer in the
well known manner.
For the purpose of incorporating with the usual roving or rovings two or more
differently coloured randoms we employ two or more auxiliary shafts and rollers.
according to the number of differently coloured randoms it is desired to incorporate
in the same yarn or thread.
The auxiliary shafts and rollers are located preferably at the rear of the ordinary
back rollers and have spur wheels on the ends from which motion is obtained.
These auxiliary shafts have an intermittent motion communicated to them
alternately by preference and are rotated part of a revolution cach time so as to
move the random roving into the path of the ordinary roving when the latter at
the time of delivery by the front rollers tensionally severs a portion of the random
roving and incorporates it therewith.
The intermittent motion may be obtained from toothed segments or mutilated
spur wheels mounted on an arbor or spindle together with a spur wheel which is
in engagement with a similar wheel actuated through the medium of suitable
intermediate mechanism from the driving shaft.
The frequency with which any one coloured random is incorporated in the yarn
is regulated by the distance apart of each series of teeth on the mutilated spur
wheels or the segments, and the length of each "random" in the spun yarn is
determined by the number of teeth placed together and which communicate more
or less movement to the random roving shaft and rollers.
To introduce the various coloured randoins into the yarn, in alternation, the
series of teeth on one segment or mutilated wheel are arranged opposite to the
spaces on the other wheels so that only one of the said auxiliary shafts and rollers
may be moved at the same time.

page_text: Improvements in the Spinning and Twisting of Fancy Yarns, and in
Machinery or Apparatus therefor.
We, WILLIAM ERNEST BARFOOT and SYDNey Charles HOBSON of the Firm
of T. W. Rust & Co. of St. Nicholas Square, Leicester, 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 spinning and twisting of fancy yarns and consists
essentially of an improvement upon the spinning and twisting of that class of fancy
yarns in which n "random or portion of a coloured thread is incorporated with
the roving or ravings in the process of spinning and twisting.
11
Heretofore, as far as we are aware, it has been considered not practicable to
incorporate more than one coloured “random” during the spinning and twisting of
the vari, but after a series of experiments we have devised ineans by which two or
1 ore rand ams of different e dours may be combined in succession in one threat
or yn during the spinning and twisting thereof.
"
fa carrying out our invention the ordicary roving passes as usual between the back
rollers, thence to the carrier rollers and front rollers and finally to the flyer in the
well known o anner, and for the purpose of incorporating with the sail roving or
rovings two or more differently coloured randoms in succession we employ two or
more auxiliary shafts and rollers, according to the number of differently coloured
randoms it is desired to incorporate in the same yarn or thread.
These auxiliary shafts have an intermittent motion communicated to them
alternately and are rotated part of a revolution each time so as to move the ramlom
roving into the path of the ordinary roving when the latter at the time of delivery
by the front rollers tensionally severs a portion of the random roving and
incorporates it therewith.
The intermittent motio is obtained from toothed segments or mutilated. spur wheels
mounted on an arbor or spindle together with a spur wheel which is in engagement
with a similar wheel actuated through the medium of suitable intermediste
mechanism from the driving shaft.
For the purpose of enabling the invention to be the better understood we append
hereto denwings in which,
Figure 1 is a vertical section on the line A A of Figure 2 and,
Figure 2 is a plan of sufficient of a spinning frame to show our invention which
is applied thereto and,
Fi
Figure 3 is an end view of a portion of the frame showing such only of the gear
wheels as are deemed necessary to illustrate the present improvements.
A represents the ordinary roving or rovings which in the course of their travel
to the flyer B, pass through the guido A, between the usual back rollers C, under
a separating wire K, between the outer teeth of a comb K, through carrier
ollers (and front or drawing rollers D, in the manner well understood by those
nequainted with the art of spinning.
E are the bobbins containing the random or differently coloured threads from any
two of which (according to the construction of machine as shown) the said threads pass
between one or other of the two pairs of auxiliary rollers FF GG over the
separating wire K through the comb or vertically slotted plate K' thence through
the carrier rollers C and delivery rollers D when by the action of the flyer a short
length of the random threads becomes incorporated with the rovings.
The rovings A are continuously travelling under the before mentioned rollers and
to the flyer B as will be well understood, while the random threads have alternately
an intermittent travelling motion towards the flyer and when a portion of either of

page_text: the said random threads is projected into the path of the rovings the latter during the
twisting or doubling operation engages the random and between the intervals of its
motion tensionally drafts or detaches a portion of the latter, and as the two threads
are projected alternately into the path of the rovings a portion first of one and
then of the other random is successively incorporated with the thread when
doubled.
The random thread F1 passes through the guide F2 between the two auxiliary
rollers FF over the separating wire K between two of the centre teeth in the
comb K', thence through the carrier rollers C¹ and drawing rollers in the usual
manner.
The random F3 passes over the spindle of the upper roller F* through the inter-
mediate guide G between the pair of auxiliary rollers GG*, thence over the spindle
of the under back roller C, over the separating wire K and between two of the
centre teeth of the comb K to the carrier rollers C', and front rollers D, in the usual
manner.
The bottom auxiliary rollers F G are mounted on supplementary shafts H J each
of which has a toothed wheel thereon HJ respectively, Figures 2 and 3, from
which it receives motion.
As before mentioned these shafts and rollers have an intermittent motion imparted
to thein which is obtained through the medium of two mutilated gear wheels H2J 2
which together with the spur wheel L are all carried on the arbor or spindle L¹ so
that the three wheels revolve together as one wheel.
The spur
wheel L is already on existing frames and gears with the spur wheel L 2
on the end of the back roller shaft L3 to revolve the latter.
The said wheel L derives its motion from gear wheels M M and pinion M 2 the
latter being on the end of the front or drawing roller shaft M3 which is driven in
the well known manner.
Next to the wheel on the arbor L' is the central or mutilated spur wheel J 2
which gears direaly with the spur wheel J' on the supplementary shaft J and partly
rotates the latter and the auxiliary rollers G G thereon at each revolution, the
random thread F 3 passing between the latter being thereby projected into the track
of the rovings A as hereinhefore mentioned.
The other mutilated gear wheel II 2 actuates the supplementary shaft H and
auxiliary rollers F F thereon through the medium of gear wheels H 2 H2 H¹
the latter being on the end of the said shaft H and the two others on arbors N N'
respectively connected to the framing N 3 of the machine.
The rollers F F* and the random thread F1 passing between them are partly
rotated and projected forward respectively at each revolution of the wheel H2 with
the result that a certain portion of the thread F becomes incorporated with the
rovings A as herein before mentioned.
From the foregoing it is obvious that so long as the supplementary shafts HJ
and their respective rollers continue to have an alternate intermittent motion
imparted to them a portion first of one and then of the other of the two random
threads will be incorporated in succession in the thread or yarn as it is doubled.
It is also clear that the length of random to be incorporated is dependent upon
the number or series of teeth placed together in succession on the mutilated gear
wheels and which being either more or fewer in uumber will effect a corresponding
increase or decrease in the partial rotary movement of the auxiliary rollers and in
the length of the thread noved forward thereby into the path of the rovings.
The frequency with which any one coloured random is incorporated in the yarn
is regulated by the distance apart of each series of teeth on the mutilated spur
wheels and to ensure the different-coloured randoms following in succession, the
series of teeth cn one mutilated wheel must be opposite the spaces on the other
wheel so as to prevent simultaneous motion of the supplementary shafts HJ.
The upper rollers F* G* rest upon the lower rollers F G and are driven by
frictional contact therewith in the same manner as the presser rollers of the frout
and back roliers of the machine as will be well understood.

page_text: The improved machine as hereinbefore described and shown in the annexed
drawings is constructed so as to permit of two differently coloured randoms being
successively incorporated in the thread during the spinning and twisting thereof but
for a greater number of differently coloured randoms to be so incorporated a further
supplementary shaft and auxiliary rollers and driving gear must be employed for
every additional random it is decided to use.
The bobbins Aare omitted in Figure 2 for the sake of clenruess, the rovings A
in this figure are therefore shown as broken off and first entering the guide A
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
:―
1. The improvement in the spinning and twisting of fancy yarns which consists
in incorporating two or more differently coloured randoms in succession in the same
yarn substantially as described.
2. In a machine for the spinning and twisting of fancy yarns wherein two or
more differently coloured rakloms are incorporated in succession the combination
with the front and back rollers of two or more supplementary shafts and auxilinry
rollers thereon and mechanism for alternately actuating the said shafts and rollers
substantially in the manner and for the purpose described.
3. In a machine for the spinning and twisting of fancy yarns wherein two or
more differently coloured randoms are incorporated in succession in the same yarn,
