IMPROVEMENTS IN YARN WINDING MACHINERY
Year: 1884

page_text: I FERDINAND ROSSKOTHEN at present residing at Accrington in the County of
Lancaster, Engineer do hereby declare the nature of the said invention for
IMPROVEMENTS IN YARN WINDING MACHINERY to be as follows:-
My invention relates to the machinery employed in the winding of yarn and has
for its object to wind the yarn into a form which will bear handling and packing
without the use of the flanched bobbins. I drive the spindle or tube upon which
the yarn is wound by surface contact with the coil of yarn and I impart a quick
traverse to the guides so that the yarn is wound in quick spirals which cross cach
other as has been done previously to my invention. In my invention the yarn
proceeds from the guides at an angle which is about a tangent to the spiral and
this necessitates that the guide shall move beyond oach end of the coil. When the
guide has reached the end of its traverse in one direction I cause it to be reversed
suddenly or by a quick movement into position to commence a return coil the angle
of direction of the yarn being reversed. This quick movement at the commence-
ment of each traverse may be obtained by employing a suitably formed cam or by
a modified form of heart wheel or by other means. I prefer to so arrange the
guido bar with relation to the coil of yarn or to so form the notch or guide as that
the length of the yarn extending from the guide to the coil shall increase as the
coil increases in diameter whereby I obtain a shortening of the lengths of the spiral
coils as the coil of yarn is built up. I drive the coils on each side of the frame by
means of one large drum or by means of a set of drums or pullies on one shaft or
I drive the said coils in the ordinary way. To stop the coiling when an end breaks
I nount each spindle in a lever frame which is connected by means of a catch and
teeth or of a holding dog with a lifting lever from which fingers are suspended.
Each finger is kept out of the way of a vibrating bar by one of the ends of yarn as
it passes to the guide but when the end breaks the finger falls towards the said bar
and is lifted thereby whereby the free end of the lifting lever is raised and acting
through the catch lifts the lever frame and as a consequence lifts the coil from
contact with the driver. The catch connection of the lever and lever frame permit
of the movement of the latter due to the building up of the coil. Hinged_catches
retain the frames in their raised positions until released by the attendant. In some

page_text: cases to economise space I arrange the contact driving shafts across the frame at
right angles to the ordinary position and drive them by means of a drum or of
pullies on a shaft which extends in the direction of the length of the frame. I
drive one two or more coils by each end of each contact driving shaft. To lift any
coils when an end breaks I employ a modification of the stop motion hereinbefore
referred to. A weighted lever is kept out of action by means of a hinged catch
and fingers are suspended from the said catch. The vibrating bar by striking one
of the fingers knocks off the said catch whereby the weighted lever is released and
a curved plate or suitably shaped part on the upper end of the lever passes between
the coil and the contact driver and raises the former out of contact...

page_text: I FERDINAND ROSSKOTHEN at present residing at Accrington in the County of
Lancaster, Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN YARN WINDING MACHINERY" and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement, and, accompanying drawings:—
My Invention relates to the machinery employed in the winding of yarn and
has for its object to wind the yarn into a form which will bear handling and
packing without the use of the flanched bobbins. I impart a quick traverse to the
guides so that the yarn is wound in quick spirals which cross each other as has
been done previously to my invention. In my invention the yarn proceeds from
the guide at an angle which is a tangent to the spiral and this necessitates that tho
guide shall move beyond ench end of the coil. When the guide has reached the
end of its traverse in one direction I cause it to be reversed suddenly or by a quick
movement into position to commence a return coil the angle of direction of the
yarn being reversed. This quick movement at the commencement of each traverse
may be obtained by employing a suitably formed cam or by a modified forın of
heart wheel or by other means. I prefer to so arrange the guide bar with relation
to the coil of yarn or to so form the notch or guide as that the length of the yarn
extending from the guide to the coil shall increase as the coil increases in diameter
whereby I obtain a shortening of the lengths of the spiral coils as the coil of yarn
is built up. I drive the coils on each side of the frame by surface contact with one
large drum or by means of a set of drums or pullies on one shaft.
In some cases to economise space I arrange the contact driving shafts across the
frame at right angles to the ordinary position and drive them by means of a drum
or of pullies on a shaft which extends in the direction of the length of the frame.
To lift any coil when an end breaks I employ a stop motion consisting of a
weighted lever which is kept out of action by means of a hinged catch, fingers
being suspended from the said catch. The vibrating bar by striking one of the
fingers knocks off the said catch whereby the weighted lever is released and a
curved plate or suitably shaped part on the upper end of the lever passes between
the coil and the contact driver and raises the former out of contact.
Fig: 1 of the accompanying drawings is a diagramatic side and end view of a
coil of yarn a with indications of the relative positions of the thread guide b at
different periods in its traverse. In order to wind the yarn spirally upon the
revolving coil a it is necessary that the thread guide b should at all times be in
advance of the point of contact c of the yarn with the coil so that the yarn shall
always lie tangentially to the part of the curve which is being wound. In Fig: 1
b shows the position of the thread guide when it has completed its traverse in the
direction of the arrow and has wound the spiral c, d upon the coil a. At this
point the traverse of the thread guide is suddenly reversed so as to bring it into
the position marked b¹ which it will be observed is again in advance of the point of
contact c, the yarn occupying the same tangential angle as formerly but in the
opposite direction. On completing the return traverse and arriving at the point 6*
the same quick reversal of the thread guide takes place into the position marked bª.
The movements of the thread guide from b' to 6' and from 6 to b are made at the
usual uniform speed but the reversals from 6 to 6¹ and from 6 to b³ are made as
quickly as is practically possible,

page_text: Having now 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. The method of winding yarn by the use of quickly traversing guides which
are accelerated in movement at the commencement of each traverse substantially
as and for the purpose set forth and indicated.
2. The use of the cam or of the heart wheel formed to impart the accelerated
movement to the yarn guides so as to bring them as rapidly as possible into the
positions indicated by b¹ and b³ in Fig: 1 substantially as and for the purpose set
forth and indicated.
3. The methods of concing the ends of the coils of yarn substantially as set forth
and indicated with reference to Figs 4 to 7 of the drawings.
4. The combination of parts arranged substantially as and for the purpose set
forth and indicated with reference to Figs 8, 9 and 10 of the drawings.
5. Coiling the yarn by means of revolving cylinders arranged with their axos
across the frames at right angles to the main driving shaft substantially as and for
the purpose set forth and indicated with reference to the last named Figs.
6. The stop motion substantially as and for the purpose set forth and indicated
with reference to Fig: 11 of the drawings.
