Under Clearers for Drawing Frames and other Machinery Employed
in Preparing and Spinning Cotton and other Fibrous Materials.
We, JOHN BUTLER of Alexandra Mill, Cotton Spinner, and THOMAS HOWARTH of
30 Wolfenden Street, Mechanic, both of Bolton in the County of Lancaster, do hereby
declare the nature of our said invention to be as follows :-
Our invention relates to providing revolving under clearers to the rollers of drawing
frames and other machinery employed in preparing and spinning cotton and other
fibrous materials for the purpose of removing "fly,
66 fluff," and other imperfections
gathered from the sliver or yarn passing over the same, thereby producing cleaner
and better yarn.
In a vibrating frame or frames disposed below the ordinary rollers are mounted
suitable rollers; the frame or frames being attached to a double lever or lovers
mounted on centres attached to fixings or their equivalents secured to the framing
of the machine in any suitable way. The outer end of the double lever or levers is
fitted with sliding weights, or other suitable equivalents, for the purpose of adjusting
the pressure of the under clearers against the ordinary drawing or other rollers. The
vibrating frame or frames are provided with a metallic roller disposed immediately
below the feed roller, and others of wood or other suitable materials under the third
and fourth drawing or other rollers or otherwise according to the class of machine
our invention may be applied to. The said clearing rollers are enclosed in an endless
band or cloth, which revolves by the action of the food roller and the pressure given
to it by the lever or its equivalent and the vibrating frame, and operates on the under-
side of the ordinary drawing or other rollers clearing them of the imperfections before
named at a point below the travel of the sliver or yarn being operated upon.

in Preparing and Spinning Cotton and other Fibrous Materials.
We, JOHN BUTLER of Alexandra Mill, Cotton Spinner, and THOMAS HOWARTH of
30 Wolfenden Street, Mechanic, both of Bolton in the County of Lancaster, do hereby
declare the nature of our said invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
Our invention relates to providing revolving under clearers to the rollers of drawing
frames and other machinery employed in preparing and spinning cotton and other
fibrous materials for the purpose of removing "fly," " fluff," and other imperfections
gathered from the sliver or yarn passing over the same, thereby producing cleaner
and better yarn.
In a vibrating frame or frames disposed below the ordinary rollers are mounted
suitable rollers; the frame or frames being attached to a double lever or levers
mounted on centres attached to fixings or their equivalents secured to the framing of
the machine in any suitable way. The outer end of the double lever or levers is fitted
with sliding weights or other suitable equivalents for the purpose of adjusting the
pressure of the under clearers against the ordinary drawing rollers. The vibrating
frame or frames are provided with a metallic roller disposed immediately below the
feed roller, and others of wood or other suitable materials under the third and fourth
drawing rollers or otherwise according to the class of machine our invention may be
applied to. The said clearing rollers are enclosed in an endless band or cloth which
revolves by the action of the feed roller and the pressure given to it by the lever or its
equivalent and a vibrating frame, and operates on the underside of the ordinary
drawing or other rollers, clearing them of the imperfections before named at a point
below the travel of the sliver or yarn being operated upon.
Fig. 1 is a sectional side elevation of our invention through line WX in Fig. 2—
Fig. 2 is a plan and Fig. 3 a front elevation of same.
In the vibrating or oscillating frame A disposed below the ordinary rollers B, C, D,
and E are mounted the rollers F, G, and H, provided with the centres I on which
they revolve in their bearings in the frame A. The frame A is fitted with the bar or
support J for the purpose of attaching it to the double ended lever K mounted on the
centre L in the fixing M secured to the roller beam N of the machine. The bar or
support J is secured to the frame A by the centres O which allow the frame to swivel
in either direction. The metallic roller H in the vibrating frame A is disposed
immediately below the feed roller E; the rollers F and G being of wood or other
suitable materials, the roller G being placed under the third roller C and the roller F
under the fourth roller B, which may be varied according to the class of machine our
invention may be applied to. The rollers F and G when made of wood or other similar
materials are provided with the metallic ends P secured thereto in any convenient
manner and are provided with the centres I. The object of the metallic ends P is to

page_text: minimise friction and ensure the under clearer revolving. The rollers F, G, and H
are enclosed in the endless band or cloth R which revolves or travels by the action of
the feed roller E and the pressure applied thereto by the lever K and adjustable
weight S and operates on the underside of the rollers B, C, D, and E, by which they
are cleared of "fly." "fluff," and other imperfections at a point below the travel of
the sliver or yarn T being operated upon. The vibrating frame A mounted on the
centres O is held in position and the rollers F and G with the endless band or cloth R
against the rollers B and C by the metallic roller H being in contact with the feed
roller E.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is :-
1. In combination with the endless band or cloth and its supporting & guiding
rollers a vibrating or oscillating frame and pivoted support attached to a lover provided
with a weight for the purpose of placing the endless band or cloth and its supporting
and guiding rollers against the underside of the drawing rollers to drive and maintain
the working position of the same, substantially as described and as shown on the
drawings.
2. The general construction or arrangement and combination of parts forming our
improved under-clearers, applied and operating substantially as and for the purposes
herein set forth and as shown on the drawings.
