IMPROVEMENTS IN WET SPINNING FRAMES FOR FLAX AND SIMILAR FIBRES
Year: 1884

page_text: _PROVISIONAL SPECIFICATION,
I, CHARLES HUGH MOCALL of Banbridge County Down, Ireland Mill Manager
do hereby declare the nature of my invention for IMPROVEMENTS IN WET SPINNING
FRAMES FOR FLAX AND SIMILAR FIBRES, to be as follows:-
The application of a revolving brush to the bottom or front drawing roller of
wet spinning frames, for the purpose of keeping the rollers clean, and so preventing
the formation of "specks" on the yarn. This brush is caused to revolve slowly in
the samo direction as the roller, with which it comes in contact at each revolution,
and so picks up any particles of dirt or short fibre that may be left on the surface
of the drawing roller, and which if not removed grow gradually larger and are
eventually spun up on the yarn, forming what is technically known as a "roller
Jump."
Owing to the comparatively slow movement of the brush, when the bristlos aro
below the centre, the water carries off a good portion of the dirt from the bristles,
and lets it drop on to the thread plate, or gutter behind the spindles.
The thicker dirt which adheres to the base of the bristles can easily be removed
by a coarse comb, or other suitable instrument,
The revolving brushes aro made in convenient lengths and supported by
adjustable bearings, so as to be always in contact with the surface of the bottom or
drawing roller.
By the use of these cleaning brushes, the yarn is kept free from dirt or "specks,"
and as the brushes are practically self cleaning, there is no extra work entailed in
minding the frame, and a superior yarn is produced.
In addition, the moisture is not removed from the surface of the drawing roller,
which is an important element in wet spinning.

do hereby declare the nature of my invention for IMPROVEMENTS IN WET SPINNING
FRAMES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention consists in the application of a revolving brush to the bottom or 5
front drawing roller of wet spinning frames and this application will be understood
from the following description, reference being had to the drawing herewith in
which the same letters and figures of reference always apply to the same or like
parts.
Fig. 1 is a sectional view of so much of a wet spinning frame as is necessary to 1
shew the application of the revolving brush and Fig. 2 is a front view of the
drawing rollers and brush with the pressing rollers removed.
The revolving brush (a) is formed of a series of bosses (a') corresponding in
pitch with the bosses (c) of the drawing roller, these bosses (a¹) are attached to a
shalt or tube (a³) carried by convenient supports or bearings (b) in such a position 1
that a portion of the bristles (a) comes into contact with the surface of 'the lower
drawing roller (c) as it revolves; The brush (a) is caused to revolve either so that
the surface in contact goes in the same direction as surface of the roller (o) as
indicated by the arrow in the drawing fig. 1. but at a much slower speed-Or it
may turn slowly in the opposite direction, in either caso the difference in speed or 2
direction of rotation causes the brush (a) to pick up any particles of dirt or short
fibre that may be left on the surface of the drawing roller (c).
The required rotary motion is communicated to the brush (a) either by a
shaft (d) and wheels connected to the ordinary traverse shaft or by a train of
geering (e) at the end of the rollers as shewn in dotted lines fig. 1, or in any other ?
convenient manner.
Owing to the comparatively slow movement of the brushes (a) when the bristles
are below the centre (a') on which they turn the water dropping from the
rollers (c) carries off a good portion of the dirt from the bristles (a) and causes it
to drop on to the thread plate (f) and thence into the gutter which is usually 3
behind the spindles (g), the thicker dirt which adheres to the base of the bristles (a)
can be easily removed by a coarse comb or other suitable instrument.
The revolving cleaning brushes (a) are made in convenient lengths and being
supported in adjustable hearings (b) can be readily set so as to come in contact as
they revolve with the surface of the bottom or drawing roller (c).

page_text: By the use of these revolving cleaning brushes (a) the yarn being spun is kept
free from dirt.or specks and as the brushes (a) are practically selfcleansing there is
no extra work entailed in minding the frame and a superior yarn is produced.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The application of revolving brushes to the bottom or drawing rollers of wet
spinning frames for the purpose of keeping them clean whilst working.
