Improvements in Knock-off Motions of Combing Machines.
We, EDWARD JAMES SMITH, of Anchor Works, Dudley Hill, Bradford, in the
County of York, Slubbing Comber, and CHARLES SWAINE, of 12, Cromwell Terrace,
Halifax, in the said County, Combing Overlooker, do hereby declare the nature
of this invention to be as follows:-
This invention relates to certain improvements in knock off motions of comb-
ing machines, and has for its object, the construction of the feeler levers of the
knock off motion in such a manner that, we are enabled to comb soft short fibre
with an opener sliver without breaking the sliver so readily, and thereby stopping
the machine so often as when the feeler levers are constructed in the manner
as hitherto also by the novel construction of the feeler levers, for the affected
lever to act when the sliver is broken and stop the machine sooner than is the
case when arranged in the ordinary manner, and thus reduce the liability of the
broken sliver lapping around the drawing off rollers and damaging the pins on
what is commonly termed the small circle of the machine.
In carrying out this invention, the sliver is drawn from the comb circle, and
the feeler levers mounted on the combing machine somewhat in the ordinary
manner, one arm of the feeler lever resting upon the sliver as it leaves the draw-
ing off rollers.
Instead of making the aim of the feeler lever that rests upon the sliver solid,
as hitherto, it is made hollow, and in the hollow portion of the lever is inserted
a ball which is kept at the fulerum end of the hollow portion of the said lever
by the sliver elevating the hollow portion above the horizontal so long as the
said sliver is intact, but when broken, the hollow portion of the lever descends,
thus allowing the ball to travel towards the out end of the said lever, thereby
causing the lever to act quickly and liberate the stop motion.

page_text: of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement:-
This invention relates to certain improvements in knock off motions of comb-
ing machines and has for its object, the construction of the feeler or detector levers
of the knock off motion in such a manner that, we are enabled to comb soft short
fibre with an opener sliver without breaking the sliver so readily, and thereby
stopping the machine so often as when the feeler or detector levers are con-
structed in the manner as hitherto; also by the novel construction of the feeler
or detector levers, when a sliver is broken for the affected lever to stop the
machine sooner than is the case when the levers are arranged in the ordinary
manner, and thus reduce the liability of the broken sliver lapping around the
drawing off rollers and damaging the pins on what is commonly termed the small
circle of the machine.
In describing our invention in detail, reference is made to the accompanying
sheet of drawings in which Fig. 1 represents a diagramatic plan of the comb
circles of an ordinary combing machine, with our invention added thereto and,
Fig. 2 is a detached detailed elevation partly in section of our improved feeler
or detector levers.
In carrying out this invention, the sliver is drawn from the comb circles A, B,
and C, in the ordinary manner, and the feeler or detector levers are also mounted
on the combing machine in the usual manner, one arm of each feeler or detector
lever resting upon the sliver as it leaves the drawing off rollers as hitherto.
Instead of making the arms D, and E, of the feeler or detector levers resting
upon the sliver solid as hitherto, they are made hollow, and in the hollow portion
is inserted a ball F, which is kept at the fulcrum end of the hollow portion of
each lever, by the respective slivers elevating and sustaining the said levers above
the horizontal somewhat as shown by Fig. 2, so long as the respective sliver is
intact, but when broken the hollow arm D or E descends into the position shown
by dotted lines in Fig. 2, thus allowing the ball within same to travel towards
the out end of said feeler or detector lever, causing the feeler or detector lever to
descend and act quickly upon the rod G, which is in connection with a lever
and catch of a stop motion such as is described in Specification No. 134 of 1897.
By making the feeler or detector arms D and E hollow, the weight resting
upon the sliver is reduced, thus enabling a sliver composed of short fibre to be
delivered in an opener state, that is with less twist therein, than is the case when
the feeler or detector arms are made solid as hitherto; and by placing a ball F,
therein as described, when the elevation of the feeler or detector arins descend
below the horizontal, the ball F therein running to the out end, adds effective
weight to the arm 1 or E, thus more readily actuating the 1od G in the direction
of the arrow, liberating the lever and catch of a motion such as is described in
the before mentioned specification, thereby stopping the machine; the said
hollow arms D and E are supported by brackets and pins J, as is the case when
solid feelers or detectors are employed, and the funnel K is operated as hitherto.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
Hollow feeler or detector arms D and E each provided with a ball F combined
with a rod G attached to the relief lever of an ordinary and suitable stop motion,
arranged substantially as herein before set forth and illustrated.
