PROVISIONAL SPECIFICATION.
Improvements in the Spinning and Twisting of Yarns, and in
Machinery or Apparatus therefor.
We THOMAS KITSON, of 73 Noble Street, Leicester, Engineer, and JOHN
THOMAS FORSELL of Frog Island, Leicester, Spinner, do hereby declare the
nature of this invention to be as follows:-
This invention has reference to the spinning and twisting of yarns and in
machinery or apparatus therefor, the nature of which is hereinafter set forth.
The invention relates mainly to the production of what are known as fancy or
mixed yarns, i.e. yarns composed of more than a single colour.
These are produced in various ways; either by twisting together two or more
yarns of different colours, or by dyeing the yarn separately for each colour
leaving exposed to the action of the dye only those portions to be dyed, this
process being called the "tie and dye" process.
The same result is also obtained by two well known processes viz. :-first
spinning the yarns in the usual way, then taking two or more yarns separately
so produced and twisting them together and causing them on their way to the
flyer to pass in or across the path of a differently coloured yarn, engage a portion
of such yarn, tensionally sever it and twist or incorporate it between the two
threads being twisted together so that the thread when complete has a coloured
portion at intervals in its length, such coloured portion being called "a random."
The present invention relates to an improvement on the last named method
of producing fancy yarns in which a random is incorporated.
The object of this invention is to produce a fancy yarn such as described, by
a single process instead of by two separate and distinct processes as heretofore.
For this purpose instead of first spinning the yarns in the usual manner and
then twisting together two or more yarns and incorporating the random as before
described, we propose to incorporate the random simultaneously with the spinning
of the thread or yarn.
To obtain this result I prefer to employ a circumferentially grooved roller or
rollers or their equivalent through the grooves of which the thread or threads
pass on their way to the flyer.
Over that higher portion of the circumference of the said roller between the said
grooves, the coloured thread passes from which the random is intermittently
severed.
The said roller has the usual top tension or feeding roller thereon and has an
intermittent motion imparted to it so that the coloured thread is periodically
projected in the course of the other thread or threads as it or they proceed to
the flyer.
By means of the above invention we are enabled also to combine a random with
a single thread whereas heretofore two or more threads were required for this
purpose.

page_text: Improvements in the Spinning and Twisting of Yarns, and in
Machinery or Apparatus therefor.
We, THOMAS KITSON of 73 Noble Street, Leicester, Engineer, and JOHN
THOMAS FORSELL of Frog Island, Leicester, Spinner, do hereby declare the
nature of this invention and in what manner the same is to be performed to be
particularly described aud ascertained in and by the following statement:-
.
This invention has reference to the spinning and twisting of yarns, and in
machinery or apparatus therefor, the nature of which is hereinafter set forth.
The invention relates mainly to the production of what are known as fancy
or mixed yarns, i.e. yarns composed of more than a single colour.
These are produced in various ways, either by twisting together two or more
yarns of different colours, or by dyeing the yarn separately for each colour, leaving
exposed to the action of the dye only those portions to be dyed, this process being
called the tie and dye process.
The same result is also obtained by two well known processes viz. first spinning
the yarns in the usual way then taking two or more yarns separately so produced
and twisting together and causing them on their way to the flyer to pass in or
across the path of a differently coloured yarn, engage a portion of such yarn,.
tensionally sever it and twist or incorporate it between the two threads being
twisted together so that the thread when complete has a coloured portion at
intervals in its length such coloured portion being called "a random."
The present invention relates to an improvement on the last named method of
producing fancy yarns in which a "random" is incorporated.
The object of this invention is to produce a fancy yarn, such as described, by a
single process, instead of by two separate and distinct processes as heretofore.
For this purpose instead of spinning the yarns in the usual manner and then
twisting together two or more yarns and incorporating the "random
as before
described, we propose to incorporate the "random" simultaneously with the
spinning of the thread or yarn.
وو
To obtain this result we prefer to employ a circumferentially grooved roller or
rollers or their equivalent through the grooves of which the thread or threads
technically termed the roving or rovings pass on their way to the flyer.
Over that higher portion of the circumference of the said roller between the said
grooves, there passes the coloured thread technically termed a roving from which
the "random is intermittently severed.
"
The said roller has the usual top tension or feeding roller thereon and has an
intermittent motion imparted to it so that the coloured thread or roving is
periodically projected in the course of the other roving or rovings as it or they
proceed to the flyer.'"
By means of the above invention we are enabled also to combine a random with
a single roving whereas heretofore two or more threads were required for this
purpose.
The invention will be fully understood from the following further description in
reference to the accompanying drawings wherein,
Figure 1 is. a front elevation and. Figure 2 a section of so much of a worsted
spinning frame as is necessary to illustrate this invention.
Figures 3, 4, 5, & 6 are details, hereinafter referred to.

page_text: A. A represent the roving or rovings; B. C. D. the back. or feed rollers
between which the rovings pass; E. F. the front or. drawing rollers which conduct
the said rovings to the flyer G, all of which are and may be constructed and
operated in the well known manner.
M
H represents the roving from which the random is severed and which is of a
different colour from the rovings A. A¹.
This coloured roving H passes through the eye J and over an intermittently
moving auxiliary roller K.
The said auxiliary roller K, (shown in section in Figures 2 and 6 and in dotted
lines in Figure 1) is mounted on a supplementary shaft Khaving bearings K' in
the framework and has on its end a small toothed wheel L which is intermittently
rotated by a mutilated toothed wheel L' revolving with a spur wheel L' at the
side thereof and on an axle M supported in an arm M' connected to the framework.
The said
spur
wheel L' engages and is actuated by a pinion N on the front
roller shaft N', the latter being driven by a larger spur wheel O thereon meshing
with a pinion O¹ receiving its motion from the boss O' of a pulley O³ driven from
the driving shaft in the usual well-known manner.
The said auxiliary roller K may have circumferential grooves K* K** therein
for the rovings A A¹ to travel in and the random or coloured roving H from the
bobbin H¹ may pass over the higher elevation of such roller as shown in the detail
figures Figs. 5 and 6.
Or the auxiliary roller K may have a plain circumference as in Fig. 2 so that
the complement of rovings travel over the said roller on the same level towards the
flyer G.
A small tension roller P of usual construction (shown in dotted lines only in
Figure 1) and the spindle P¹ of which is carried in the bearings K' attached to the
framing of the machine, rests loosely on the said auxiliary roller K.
The pressure of the tension roller P may be regulated by means of a wing-nut P'
on the screwed upper end of a rod P' furnished with a hooked extension in contact
with the tension roller spindle P' as shown in Figure 4.
The rovings A. A' as is well understood have a continuous motion towards the
flyer G and the coloured roving H from which the random is obtained has only an
intermittent movement.
Upon the mutilated gear L' engaging the toothed wheel L and partially rotating
it and the shaft K', the auxiliary roller K on the latter draws forward a portion of
the coloured roving H into the path of the rovings A A¹ so that the said coloured
roving is engaged by the latter and a portion thereof subsequently severed by
tensional strain and incorporated with the rovings A A¹ during the spinning of the
thread R which subsequently passes to the flyer G and is wound on the bobbin R¹
in the usual manner.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. The construction of a spinning and twisting machine in such a manner that a
roving of one colour may be intermittently moved into the path of a roving or
rovings of a different colour and portions thereof incorporated at intervals with the
latter for the purpose described.
2. In the spinning and twisting of fancy or mixed yarns, a continuously
travelling roving or rovings and an intermittently travelling roving of a different
colour and means for effecting at intervals the incorporation of a portion of such
coloured roving with the continuously travelling roving or rovings.
3. In a spinning and twisting machine the provision of means for intermittently
moving a coloured roving into the path of the usual roving or rovings so that a
portion of such coloured roving becomes tensionally severed and incorporated at
intervals with the latter for the purpose described.

page_text: 4. In a spinning and twisting machine the combination with the back and front
rollers of an intermediate intermittently moving roller substantially as and for the
purpose described and illustrated in the accompanying drawings.
