1, ERNEST KNOWLES of Mossfield and Egyptian Mills, Bolton in the County
of Lancaster, Cotton Spinnet, 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 improvements in under-clearers applied to the rollers
of drawing, slubbing, intermediate, loving, and other similar frames employed in
preparing cotton and other fibrous materials and apparatus connected therewith
for the purpose of removing "Aly," "fluff," and other imperfections from the said
rollers gathered or collected from the "sliver" or yarn when passing between the
said rollers. Below each section of the bottom rollers 1 dispose a sliding plate
covered with cloth or other fibrous material; the same being held in position

against the underside of the bottom rollers by a flat spring or springs or by a lever
or level and weights, the said spungs or levers being mounted on or attached to
an oscillating shaft operated from any convenient part of the machine or frame.
The movement of the sliding plate or plates is regulated according to the speed
of the 1ollers; the former having the same or a slower speed or traverse than the
back rollers to prevent the "sliver" being rubbed up thereby reducing waste to a

DESCRIPTION OF DRAWINGS.
Fig is a sectional side elevation of my invention for improvements in under-
clearers for drawing, slubbing, intermediate, roving, and other sunila frames
employed in preparing cotton and other fibrous materials and apparatus connected
therewith wherein the said under-cleaners are kept in position by a lever and
weight.
Fig 218 similar to Fig. 1 with the exception of the spiral sping in lieu of the
weight, and
Fig. 3 is a sectional side elevation of my invention wherein the under-cleai eis
anc caried by flat springs.
A are the top rollers, B bottom rollers and C the under-cleaners. Below or
under each section of the bottom nollers B I dispose the sliding plate C covered
with the cloth or other fibrous material E, the same being held in position and
carried against the bottom olleis B by the lever or 1od G. The level on rod G
is pivoted or secured to the under-clearers C by the pin or centre F, and to the
levci X by the pin on centic H The lever X is mounted on the shaft 1; the
latter being carried in bearings from any convement part of the machine. Each
under-cleaie C is held against the bottom 1ollers B by the weight J which may
be regulated as desired and secured in position by the set-screw K. If desired
the weight J may be substituted by the spiral spring L as shown in Fig 2. The
lower end of the spial sping L is secured to any convenient part of the machine.
In another airangement the level or 1od G is substituted by the spring M as shown
Fig. 3, in which case the said spring is attached to the pivoted end N; the
opposite end being secured to the boss O on the oscillating shaft I.
.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 :-
The general arrangements, constructions, and combinations of parts composing
the improvements in under-clearers for drawing, slubbing, intermediate, roving,
and other similar frames employed in preparing cotton and other fibrous materials
and apparatus connected therewith as hereinbefore described and as illustrated in
the annexed diawings.
