Improvements in and connected with Revolving Underclearers for
Drawing, Slubbing, and Roving Frames.
I, GEORGE KEARTON of 9 Bamford Street, Heaton Norris, near Stockport, in
the County of Lancaster, Mill Manager, do hereby declare the nature of this
invention to be as follows:-
My invention relates to revolving underclearers for drawing slubbing and roving
frames and my improvements consist in improved coverings for said underclearers
and novel or improved arrangements for supporting adjusting and rotating the
underclearers and stripping them of the waste collected by them, these arrangements
being more particularly intended for the underclearers of drawing frames but also
applicable partly or entirely to slubbing and roving frames.
Referring to the coverings my improvement consists in making said coverings
with a flexible foundation under the outer covering. The underclearer consisting
of a wooden roller with metal pivots is preferably covered with a piece of soft
india rubber tubing and flannel lapped round said tubing, but instead thereof a
foundation of soft flannel and covering of woollen plush or similar pile fabric may
be used. In consequence of this yielding foundation when an underclearer for two
fluted rollers is not accurately set so as to bear equally against both of them but
bears more against one of them, the flexible foundation can yield sufficiently to
bring the underclearer into contact with the other fluted roller to strip the same
of the fluff adhering to it.
My further improvements are hereinafter more particularly described as applied
to a drawing frame. Each of the two underclearers, one for the front and second
and one for the third and back roller, are supported in brackets with bearings
preferably open at the top for the pivots of said underclearers. The brackets are
adjustable in both directions on flat side bars connected by stays so as to form a
stiff frame. At the back end the side bars are formed with forks or saddles open
at the underside which are saddled upon a shaft rotating in suitable bearings fixed
to the roller beam. At the front ends the side bars are supported on carriers
sliding on studs screwed to the roller beam and surrounded by helical springs
which hold up the carriers and sidebars and press the underclearers against the
fluted rollers. Each stud may have a nut screwed upon the top against which the
carrier is pressed by the spring and the pressure of the undercleaners against
the rollers be regulated by adjusting the nut, or an adjustable bracket may be fixed
to the sidebars bearing against the underside of the sliver plate and the pressure
regulated by adjusting said bracket. In consequence of these arrangements for
supporting the frame it can yield and allow the underclearers to be depressed when
a roller lap occurs.
The underclearers are slowly rotated from the rotating shaft hereinbefore referred
to preferably by means of a driving chain passing round a chain pulley on said
shaft and chain pulleys fixed upon the pivots of the underclearers at one side of
the frame. The fluff or waste collected by the underclearers from the fluted rollers
is removed from the same by vibrating stripping combs. These are attached to
levers mounted on studs adjustably fixed to the same brackets that carry the under-
clearers, so that after the combs have been adjusted to the underclearers the latter
can be adjusted to the fluted rollers without disturbing the adjustment of the
combs and when the underclearers are depressed, the combs move downwards with
them. On one side the levers carrying the combs are connected by a link made in
two parts bolted together through slots so that the length of the link can be varied
when the distance between the rollers i altered for different kinds of cotton. To

tails" in the space between the rollers, which occurs with the usual arrangement
of underclearers until the space is filled and the rat tails are taken along with the
sliver and whereby faults in the yarn are caused, is prevented. One end of the
connecting rod is made as an open fork or hook and dropped or hooked upon
the pin so that it can be easily lifted off, and this combined with the support of the
frame by open saddles upon the rotating shaft and by carriers as herein before
described allows the frame with the underclearers and combs to be bodily taken
away from under the fluted rollers for the purpose of adjusting the combs to the
underclearers and adjusting the length of the link in a convenient manner.

COMPLETE SPECIFICATION.
Improvements in and connected with Revolving Underclearers for
Drawing, Slubbing, and Roving Frames.
I, GEORGE KEARTON of 9 Bamford Street, Heaton Norris, Stockport, in the
County of Lancaster, Mill Manager, 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 revolving underclearers for drawing slubbing and roving
franes and my improvements consist in improved coverings for said underclearers
and novel or improved arrangements for supporting adjusting and rotating the
underclearers and stripping them of the waste collected by them, these arrangements
being more particularly intended for the underclearers of drawing frames but also
applicable partly or entirely to slubbing and roving frames.
On the sheet of drawings appended hereunto
Figures 1 shows a longitudinal section and Fig. 2 a side view of my improved
arrangements applied to a drawing frame,
Figs. 3 and 4 similar views of a modified arrangement,
Fig. 5 sections of an underclearer with improved covering.
Referring first to the coverings my improvement consists in making said
coverings with a flexible foundation under the outer covering. The underclearer A
Fig. 5 consisting of a wooden roller a with metal pivots a is preferably covered
with a piece of soft indiarubber tubing wound around the same and flannel 1
lapped round said tubing. Instead of the rubber tube, rings or sheets of soft rubber
or equivalent flexible material and instead of the flannel woollen plush or similar
pile fabric may be used. In consequence of this yielding foundation when an
underclearer for two fluted rollers is not accurately set so as to bear equally against
both of them but bears more against one of them, the flexible foundation can yield
sufficiently to bring the underclearer into contact with the other fluted roller to
strip the same of the fluff adhering to it.
My further improvements are hereinafter more particularly described as applied
to a drawing frame with reference to Figs. 1, 2, 3, and 4 of the drawings in which
similar letters denote similar parts in all figures. CC¹ C² C³ represent the four
fluted rollers of the frame. Each of the underclearers, one A for the front roller C

page_text: and second roller C' and another A' for the third roller C² and back roller C³,
is supported in a bracket d with bearings preferably open at the top as shown for
the pivots a' of the underclearers. The brackets d can be shifted vertically on
brackets d' horizontally moveable on the side bars e, so that the underclearers can
be adjusted on said side bars in both directions and set to touch the rollers. The
side bars e are connected by stays el fixed or cast thereto to form a stiff frame
hereinafter called clearer frame, which is hinged upon a shaft frotating in suitable
bearings (not shewn on the drawing) fixed upon the roller beam B. At the front
the frame is supported preferably on springs. In the arrangement shewn on Figs.
and 2 studs y are screwed into the roller beam B on which carriers y' slide and
are pushed upwards by springs g² which press the clearer frame resting on the
carriers upwards and the underclearers A A¹ against the fluted rollers. Adjustable
brackets are bolted to the side-bars e and bear on the top against the sliverplate D
of the drawing frame. By adjusting the height of the brackets h above the
sidebars the pressure of the underclearers against the fluted rollers or their position
relatively to the same can be regulated. Nuts y³ prevent the carriers g' from being
pushed off the studs g when the clearer frame is taken out of the machine. On
Figs. 3 and 4 a modified arrangement is shewn. Bolts i are passed through lugs e
cast on the side bars e and springs are placed on the bolts which pull the bolts
down till their heads come upon the lugs e', the pressure of the springs being
adjustable by nuts 3 screwed upon the bolts. The position of the side bars being
thus determined the underclearers A. A' are set against the fluted rollers and their
position regulated by shifting and setting the brackets d d¹. In consequence of
these arrangements for supporting the carrier frame it can yield and allow the
underclearers.to be depressed when a roller lap occurs.
The underclearers are slowly rotated from the rotating shaft f preferably by
means of a driving chain passing round a chain pulley on said shaft and chain
pulleys 123 fixed on the pivots of the underclearers A. A' on one side of the frame,
or instead thereof other suitable gearing may be used. The shaft is rotated at
one end of the machine by gearing from the main driving shaft or one of the
fluted rollers.
The fluff or waste collected by the underclearers from the fluted rollers is removed
from the same by reciprocating stripping combs.
In the arrangement shewn by Figs. 1 and 2, the combs m are attached to levers m¹
mounted on studs m² adjustably fixed to the same brackets d' that carry the
underclearers, so that after the combs have been adjusted to the underclearers the
latter can be adjusted to the fluted rollers without disturbing the adjustment of
the combs, and when the underclearers are depressed, the combs move with them.
On one side the levers m¹ carrying the combs are connected by a link n made in
two parts bolted together by a bolt n¹ passing through slots in said parts as shewn
so that the length of the link can be varied when the distance between the fluted
rollers is altered for different kinds of cotton. To the link a connecting rod o is
attached at one end and. at the other to a pin o¹ in a crank or lever o² fixed on the
rocking shaft o³ which is used for the stop motion of the machine and makes a
vibratory movement, and a reciprocating vibratory movement is thereby imparted
to the combs m whereby the waste adhering to the underclearers is combed off and
thus prevented from accumulating in the space between the rollers and being taken
along with the sliver, and making faults in the yarn as very often occurs with the
usual arrangements of stationary or revolving underclearers. One or both ends of
the connecting rod o is or are made as an open fork or hook and dropped or hooked
upon the pin o¹ so that it can be easily lifted off and this combined with the
support of the clearer frame by open saddles or their equivalents on the shaft fand
by studs or bolts at the front as hereinbefore described allows the frame with the
underclearers and combs to be bodily taken away from under the fluted rollers,
for the purpose of adjusting the combs to the underclearers and adjusting the
length of the link n in a convenient manner. The flat waste combed off drops
upon the roller beam B to which a guard plate p is attached for preventing

page_text: the waste from dropping into the cans, and the waste can be readily brushed off
the beam.
The modified arrangement shewn by Figures 3 and 4 differs from that described
with reference to Figs. 1 and 2 by the motion of the combs being rectilinearly
reciprocating instead of oscillating. The combs m are fixed to tee shaped
brackets adjustably fixed to the sliding barr' which slides in openings of the
brackets s, the latter being fixed to the cross stay e¹ of the carrier frame. The
bar is connected to the crank pin o in lever o2 by the connecting rod o, the
latter being formed at one end or both ends with an open jaw so, that it can be
lifted off, when the carrier frame with its attachments can be bodily removed '
from under the fluted roller. For slubbing and roving frames the combs may be
omitted if desired.
I am aware that carrier frames hinged upon a rotating shaft and having under-
clearers rotated by gearing from said shaft mounted thereon and held up by
balance weights against the fluted rollers have been used before for drawing
frames, but these were not so arranged that they could be bodily removed and
not provided with stripping combs.
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. Making the coverings of underclearers for drawing slubbing and roving
frames with a flexible foundation of india rubber tubing or its equivalent under the
outer covering of flannel or its equivalent substantially as described.
2. The arrangement of frames for carrying underclearers for drawing slubbing
and roving frames with open supports at the back and spring supports at the front
in such a manner that they can be bodily removed from under the fluted rollers,
substantially as described.
3. The combination with frames supporting underclearers rotated by chain
gearing or its equivalent from a revolving shaft of stripping combs to which a
reciprocating motion is imparted substantially as hereinbefore described and for the
purpose set forth.
4. The arrangements of rotating underclearers, removeable frames for sup
porting the same, and stripping combs to which a reciprocating motion is
imparted substantially as hereinbefore described with reference to Figures 1, 2, 3
and 4 of the drawings.
