Improvements in Rotary Cleaners for Drawing Rolls.
I, JAMES THOMSON, Jr., of 192 Pine Street, Pawtucket, Rhode Island, United
States of America, Overseer, 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:-
My invention relates to an improved device for clearing the waste material from
the drawing-rolls employed in cotton machinery, and it consists in the employment
of a clearing-disk having its face resting upon the rolls, with means for imparting
rotary movement to the disk. My invention also consists in imparting movement
to the clearing disk by means of yielding pressure applied to the disk at one side
of its axis, whereby the frictional action of the rolls upon the disk will serve to
impart the desired rotary movement. It also consists in so constructing the face
of the rotary clearing-disk, that the waste material will be carried by the action
of the rolls, into a recess or opening in the disk in which it may be accumulated.
It also consists in providing a rotary clearing-disk with a recess or opening, and
a waste-collecting covering adapted to yield into the recess or opening, to provide
for the accumulation of waste material.

means for rotating the clearing-disk.
Fig. 9, represents a section taken in the line 9, 9, of Fig. 8.
Fig. 10, represents a section taken in the line 10, 10, of Fig. 9.
Fig. 11, represents a sectional view of the hinged cover, showing one of the
top-rolls, and an axial section of the recessed clearing-disk shown in Fig. 6.
Fig. 12, shows a modification in the means for rotating the clearing disk.
In the drawings, Figs. 1 and 2, A represents the table of a drawing-frame,
B, B, the lower fluted rolls, C, C, the covered top-rolls, and S the cotton sliver
passing through the rolls. The drawing-rolls are provided with a cover D), which is
pivoted or hinged at the point a, and to the downwardly extending boss b, at the
inner side of the cover, is secured the bracket c, by means of the screw d, and at
the slotted outer end of the bracket c, is loosely attached the clearing-disk E, to
which rotary movement is imparted by means of the flat spring F, which is
secured under the head of the screw d, and carries at its outer end the anti-friction
roller c, which by bearing against the upper side of the disk E, over one of the
top-rolls C, causes a greater pressure upon the top-roll C, at one side of the turning
axis of the disk, than at the other, which difference of pressure will cause the
required rotary movement. And by reason of the rotary movement of the disk E,
the waste will be collected from the surface of the rolls C, and be retained in a
felted sheet upon the clearing face of the disk, the said face being provided with
a waste-collecting covering of cloth or other suitable material, which may be
made continuous over the whole hearing side of a flat disk, as shown in Figs. 2
and 3, or which may be attached to a flat clearing-disk provided with a series of
perforations t, t, as shown in Figs. 4 and 5, in which case the waste material will
he collected on the covered surface of the disk and pass to the said perforations,
or the cloth covering k, may he attached to a disk having a recess, as shown in
Fig. 6, into which the cloth covering will be forced by the accumulated waste
material w, as shown in Fig. 11, the said cloth covering being cemented or other-
wise atttached to the disk at its edges, while it is capable of yielding inwardly at
its central portion u. A continuous covering k, may also be employed with a
perforated disk, into the perforations of which the covering will be pressed by the
accumulated waste.
The rotation of the top rolls C, as indicated by the arrow in Fig. 2, is in such a
direction as to cause the journal of the disk to be retained in the open slot 1 of
the bracket c, and when the hinged cover D, is turned up for the purpose of having
access to the rolls, the weight of the disk still tends to hold the journal al in the
open slot b', and by means of said slot, the disk E, may be removed from the
bracket c, at pleasure.
A modification of my invention is shown in Figs. 8 and 9, in which the clearing-
disk E, is provided at its edge with the ratchet teeth m, adapted for the engagement
of the reciprocated spring pawl G, therewith, the said pawl being attached to the

page_text: sliding bar H, which is arranged at the inner side of the cover D, the said bar
being loosely attached to the cover by means of the slots n, n, formed in the said
bar, and the screw studs o, o. Connection is made with the reciprocating sliver-
guide I, of the drawing-frame by means of the arm p, which is secured at one end
in the extended base of the sliver-guide, the opposite end of the arm p, being held
between the pendent ears r, r, of the sliding bar H, whereby the cover D may be
turned upward on its hinges without causing the disconnection of the arm p,
from the bar H. Reciprocating movement is imparted to the guide I, in drawing-
frames, by means of a reciprocating rod J, to which the guide I, is attached, the
said guide being held for said reciprocating movement in the slots of the
table A¹. A frictional spring M, is attached to the front outer side of the cover D,
to bear upon the edge of the clearing-disk E, to prevent the backward movement
of the disk during the backward movement of the spring-pawl G. The disk will
by this means be rotated intermittently in a forward direction.
Instead of operating upon the edge of the clearing disk by means of a spring
pawl, as shown in Figs. 8 and 9, the disk E may be provided with a gear e',
adapted for engagement with the rack f', which is connected by means of the
arm g', with the sliding bar H, as shown in Fig. 12, and in this case the clearing
disk will upon the reciprocation of the rod J, of the drawing frame, be rotated
alternately in opposite directions, while bearing upon the rolls C.
Instead of applying a spring and an anti-friction roller for pressing the disk
downward upon the top-roll C, at one side of the axis of the disk, as shown in
Fig. 1, a spring F, provided with an anti-friction roller e, may be employed to
press upward upon the under side of the disk E, as shown in Fig. 7, thus causing
the side of the disk acted upon by the spring, to bear lighter upon the revolving
top-roll C, than before, and allowing the disk to be revolved by the stronger action
of the roll thereon, at the opposite side of the disk.
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. The combination of the drawing rolls, with a clearing disk having its side
arranged to bear upon the rolls, and means for imparting rotary movement to the
clearing disk, substantially as described.
2. The combination of the drawing rolls, with a clearing disk having its side
arranged to bear upon the rolls, and means for causing the clearing disk to bear
with greater pressure upon the rolls at one side of its axis, then upon the other side,
thus causing the rotation of the disk, substantially as described.
3. The combination of the drawing rolls with a rotary clearing disk provided
with an opening or recess adapted to receive the collected waste, substantially as
described.
4. A rotary clearing disk, adapted to hear upon the rolls, said disk being
provided with a recess or opening, and a waste-collecting covering adapted to yield
into the recess or opening, substantially as described.
5. The combination of the drawing rolls and the cover for the rolls, with the
clearing disk held for rotation in the cover, substantially as described.
