as follows:-

This invention relates to that class of machinery employed in the winding of yarn
upon tubes or bobbins, and consists in means for automatically cleansing the clearer
or "drag" board of fibres which have previously been deposited thereon in the
process of winding. In winding machines at present employed a serious defect
exists in the use of the stationary cloth clearer or "drag" board over which the
yarn travels in the act of winding this defect allows of the collection of "fly"
and other imperfections on the stationary cloth clearer or drag" board in large
quantities, and as the accumulation increases it is at times licked up by the travelling
yarn and passed on to the tube or bobbin. This is very detrimental to the produc-
tion of clean even yarn and detracts from the value of the same very materially.
Many contrivances have been employed with little or no success to overcome this
defect. The cause of failure is that the stationary cloth clearer or "drag" board
has not been made self-cleansing, which is the essence of this invention. This self-
cleansing I effect in the following manner :-On the front of the winding frame
I mount in suitable bearings the cloth clearer or "drag" board over which the yarn
travels in the process of winding. The cloth clearer or drag" board is made to
travel backwards and forwards laterally at right angles or thereabouts to the line
of travel of the yarn. This backward and forward lateral movement is effected by
suitable mechanism from any convenient part of the machine. The lateral motion of the
cloth clearer or "drag" board causes the yarn, in the act of winding; to be constantly
and automatically clearing the said cloth of the " fly" and other imperfections
which have been deposited thereon in the process of winding as already described
above. The lateral motion given to the cloth clearer or drag" board ensures the
cloth being worn uniformly, thereby preventing the cutting of the same as is the

cloth a great saving will be effected in the cost of renewals of the same, and
further the friction or "
drag" put upon the yarn will be more uniform inasinuch
as the yarn will always be passing over a perfectly even cloth surface.

Improvements in Winding Frames.
I, WILLIAM KNOWLES of Hartford and Round Hill Mills, Bolton in the County
of Lancaster, Cotton Spinner, do hereby declare the nature of my said 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 that class of machinery employed in the winding of yarn
upon tubes or bobbins, and consists in means for automatically cleansing the clearer
or drag" board of fibres which have previously been deposited thereon in the
process of winding. In winding machines at present employed a serious defect
exists in the use of the stationary cloth clearer or "drag" board over which the
yarn travels in the act of winding: this defect allows of the collection of "fly"
and other imperfections on the stationary cloth clearer or drag" board in large
quantities, and as the accumulation increases it is at times licked up by the travelling
yarn and passed on to the tube or bobbin. This is very detrimental to the pro-
duction of clean even yarn and detracts from the value of the same very materially.
Many contrivances have been employed with little or no success to overcome this
defect. The cause of failure is that the stationary cloth clearer or
drag" board
has not been made self-cleansing, which is the essence of this invention. This
self-cleansing I effect in the following manner :-On the front of the winding frame
I mount in suitable bearings the cloth clearer or drag" board over which the yarn
travels in the process of winding. The cloth clearer or "drag" board is made to
travel backwards and forwards laterally at right angles or thereabouts to. the line of
travel of the yarn. This backward and forward lateral movement is effected by suitable
mechanism from any convenient part of the machine. The lateral motion of the cloth.
clearer or "drag" board causes the yarn, in the act of winding, to be constantly and
automatically clearing the said cloth of the "fly" and other imperfections which have
been deposited thereon in the process of winding as already described above. The

page_text: lateral motion given to the cloth clearer or "drag" board ensures the cloth being
worn uniformly, thereby preventing the cutting of the same as is the case in stationary
cloth clearers. By removing the possibility of cutting the clearer cloth a great saving
will be effected in the cost of renewals of the same, and further the friction or "drag
put upon the yarn will be more uniform inasmuch as the yarn will always be passing
over a perfectly even cloth surface.
Fig. 1 of the accompanying drawings is a part front elevation of so much of a
winding frame as is necessary to illustrate my present invention with my improvements
applied thereto for automatically cleansing the cloth clearer or "drag" board of fibres
and other imperfections which have previously been deposited thereon in the process
of winding, and Fig. 2 is an end view of same.

A is a trough fitted with the rod B and supports C for carrying the cops D in any
suitable position, to allow of the yarn being wound onto the bobbins or tubes E
disposed on the upper side of the machine. The yarn G in the operation of being
wound from the cops D to the bobbins or tubes E passes over the clearer or drag
board H for the purpose of removing loose fibres, and other imperfections from the
yarn. Prior to this invention loose fibres and other imperfections have been allowed
to collect on the clearer or "drag" board in large quantities, and as the accumulation
increased it was at times licked up by the travelling yarn and passed onto the bobbin
or tube, thus preventing the production of clean even yarn.
My invention consists in the removal of this defect and this I accomplish in the
following manner :-The front of the winding frame is fitted with the bearings F in
any convenient manner according to the construction of the winding frame. On the
bearings F is mounted the clearer or "drag" board H covered in the usual manner
with cloth. The cloth clearer or "drag” board H is made to travel backwards and
forwards laterally at right angles or thereabouts to the line of travel of the yarn. This
to and fro lateral motion of the cloth clearer or "drag" board H causes the yarn, in
the act of winding, to be constantly and automatically clearing the said cloth of "fly"
and other imperfections immediately they are deposited thereon. The travel of the
cloth clearer or "drag" board H is of such a length as to allow of the "fly" and
other imperfections removed from a thread or threads of yarn and left on the cloth
clearer or "drag" board being cleared or licked up by the next thread or threads of
yarn, and so on, whether placed at regular or irregular distances, the clearing or
cleansing being effected by the cloth clearer or "drag" board H travelling beyond the
line of travel of the next thread of yarn, so as to overlap and clear the entire length
of the working parts of the cloth clearer or "drag" board H. The speed of the cloth
clearer or "drag" board H can be regulated according to the counts of yarn being
wound by simply altering the proportions of the gearing, or by altering the leverage
between the pin N and the centre S' in "any convenient manner. To the clearer or
drag" board H is pivoted the rod I by the pin J; the opposite end of the rod I
being pivoted by the pin K to the lever L'mounted on the fixing M. The lever L is
fitted with the pin N and is operated upon by the heart-cam O in such a manner as to
give an uniform speed to the cloth clearer or "drag" board H. It is most essential
that the speed of travel should be uniform so as to prevent uneven collection of loose
fibres and other imperfections on any given point, and also to prevent the yarn in the
act of travelling over the cloth clearer or drag" board being moved too-far out of
its course.
Another important feature in giving the cloth clearer or "drag" board H
an uniform travel is to prevent the yarn travelling too-long in one place, thus
minimising the possibility of cutting or grooving the cloth, by which a great saving
will be effected in the cost of renewals; and the yarn will always be travelling over a
perfectly even cloth surface, thus giving an uniform friction or
to the yarn.
The heart-cam O is attached to the shaft P mounted in the bearings secured to the
floor as shown, or any convenient part of the winding frame. On the shaft P is fixed
the worm wheel R operated by the worm S on the shaft T mounted in the bearings U.
The shaft T is fitted with the worm wheel V operated by the worm W on the shaft ✗
mounted in the bearings Y attached to the frame-end G. The shaft X is provided
with the grooved pulley Z`driven by the band A' from the grooved pulley B¹ on the
"6
"
drag"

page_text: cam shaft C of the winding frame. The gearing described above is designed
give
a slow motion to the heart-cam O, which causes the latter to push the lever L to give
a forward movement of the cloth clearer or "drag" board H; the reverse motion
being effected by the pin N on the lever I being held firmly against the heart-cain O
by means of the weight D' attached to the lever L by the band M' or its equivalent
passing over the guide pulley El pivoted to the frame G¹ of the machine.
I would have it understood that I do not confine myself to the precise details and
configuration of parts, or the arrangement of mechanism I have shown and described
for operating the heart-cam O or its equivalent, as the same may be performed in
many ways according to the design or construction of the winding frames my
improvements may be applied to.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. Moving or sliding the cloth clearer or "drag" board to and fro laterally for the
purpose of automatically clearing or cleansing the same of "fly" and other imperfec-
tions by means of the yarn itself during the process of winding, substantially as
described and shown on the drawings.
2. For operating the cloth clearer or "drag" board the construction and arrangement
of apparatus, applied and operating substantially as described and illustrated by the
accompanying drawings, or any mere modification of the same.
