Manager do hereby declare the nature of my invention for IMPROVEMENTS IN
MACHINERY FOR PREPARING FLAX HEMP AND SIMILAR FIBRES to be as follows:-
This invention consists in the application of revolving rubbers to the retaining
rollers of drawing and other frames for preparing Flax Hemp and similar fibres.
These revolving rubbers being specially designed for retaining rollers composed of
two driven rollers and a jockey roller working between and above the two driven
rollers over and under which the slivers to be drawn are passed.
The object of this invention is to prevent any of the short fibres or debris that
accumulate on the ordinary dead rubbers from falling into the sliver which passes
under and over or between the retaining rollers.
These revolving rubbers are covered with flannel or other suitable material and
are caused to revolve whilst in contact with the retaining rollers so as to pick up
any fibre or dirt that may be left on them by the slivers in their passage and so
keep the rollers bright.
The revolving rubbers are made in sections so as to be readily removed and
replaced for the purpose of cleaning etc.
By these means the retaining rollers are kept clean and the risk of the dirt that
is picked up by the revolving rubbers going into the slivers is lessened and so
cleaner yarns can be produced.

JOSHUA VALENTINE EVES of Brooklands Knock County Down, Ireland Mill
Manager do hereby declare the nature of my invention for IMPROVEMENTS
MACHINERY FOR PREPARING FLAX HEMP & SIMILAR FIBRES 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 revolving rubbers to the retaining
rollers of drawing and other frames for preparing flax hemp and similar fibres,
these revolving rubbers being specially designed for retaining rollers composed of
two driven rollers and a jockey roller working between and above the two driven
rollers over and under which the slivers to be drawn are passed.
The object of this invention is to prevent any of the short fibres or debris that
accumulates on the ordinary dead rubbers from falling into the sliver which passes
under and over or between the retaining rollers.
The means employed to accomplish this object will be understood by reference
to the drawing herewith wherein Figure 1 is a sectional view of so much of an
ordinary screw gill drawing frame as is necessary to shew the application of the
revolving rubbers (a) to the retaining rollers (6), Figure 2 is a plan view of
the geering employed to drive the rubbers (a), Figures 3. 4. 5 and 6 are
detached views of parts referred to in the following description wherein the same
letters and figures of reference always apply to the same or like parts.
The revolving rubbers (a) consist of metal shafts, tubes as in figures 1 and 4 or
wooden rollers with a metal axle as in figure 5 and are covered with flannel
or other suitable material and are caused to revolve in the direction indicated by
the arrows in figure 1, whilst in contact with the retaining rollers (b) so as to pick
up any fibre or dirt that may be left upon them by the slivers (c) in their passage
and so keep the rollers (b) bright.
To drive the revolving rubbers (a) they are connected by geering (d) at one end
of the frame to the rollers (b) and are caused to revolve in such a direction that the
surfaces in contact are moving in opposite directions.
The revolving rubbers (a) are made in sections or lengths to suit the distance
between the bearings (6¹) of the retaining rollers (b) and are connected together
and to the driving pinious (d) by having their axles made square at the ends (a');
Over these square ends (a) is placed a sleeve or coupling (a³) with a square hole
in it (see figure 6) this hole being slightly larger in the middle and the square
ends (a) of the rubbers are slightly larger at the ends so that the coupling (a³)
remains over the joint when working as shewn with the rubber (a) connected to a
centre connecting axle (a) in figure 4, or when required to be removed or replaced
for the purpose of cleaning, this is readily done by slipping the coupling (a³) from
off the end of the rubber (a¹) on to the connecting or driving axle (a*),

page_text: By these means the retaining rollers are kept clean and the risk of the dirt that
is picked up by the ordinary dead rubbers going into the slivers is lessened and
so cleaner yarns can be 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 rubbers to the retaining rollers of preparing
machinery for flax hemp and similar fibres in the manner and for the purposes
herein described.
