COME LEIE DI MULTICATION,
Improvements in or connected with Machinery for Treating Flax
and other Fibrous Materials Preparatory to Spinning.
I, JOSHUA VALENTINE EVES, of Forth River Mill, Belfast, in the County of
Antrim, Ireland, Flax Spinner, do hereby declare the nature of this 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 appliances for cleaning or preventing the accumulation
of dirt upon the rollers of drawing frames or other machines employed in the
preparation of flax and other fibres for spinning.
It has hitherto been customary to apply to both top and bottom rollers clearers
covered with flannel or other cloth to remove therefrom small pieces of fluff or dirt
which are liable to collect thereon.
This invention consists essentially in the construction of special forms of metallic
rubbers or clearers which I have found to be better adapted for the purpose and
more serviceable and durable than the textile covered rubbers or clearers which
have hitherto been used.
It will be fully described with reference to the accompanying drawings in which
as an example the invention is shown as applied to a drawing frame for flax.

Fig. 2. Ditto, showing a modified construction of the invention.
Fig. 3. Enlarged detail of top rubber or clearer.
Fig. 4. Perspective view of spiral wire rubber.
Fig. 5. Perspective view of bottom rubber or clearer.
The drawing frame is constructed in any ordinary way A being the front or
drawing roller and B the top or pressing roller.
The rubber or clearer C for the pressing roller B I form of a flat spiral D of
steel or other suitable wire. This is affixed to the body of the rubber C by pins
or screws c or other suitable means and extends across the face and being of an
elastic or springy nature readily conforms to the contour of the roller adapting
itself to the circumference of the roller as it may become reduced in size owing
to wear.
In the modification shown in Fig. 2. the spiral wire rubber D instead of being
affixed to a dead weight such as C is extended between two rods d d so as to bear
for a portion of its length upon the pressing roller B. The front rod d may be
supported from a bracket e attached to or forming part of the weight hook E and
the back rod is supported by the framing, or by the roller stands or in any
other suitable way.
The rubber or clearer F for the front or drawing roller A consists of a U or
trough shaped piece or strip of doctor drawn brass or other sheet metal the two
edges of which are placed uppermost to bear against and exert a scraping action
upon the rollers effectually removing therefrom any adhering fibre or foreign
matter. The rubber or clearer F is supported or held in position by brackets
attached to the frame beam or other part of the frame.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a frame for drawing preparing or otherwise treating flax or other fibres

page_text: a rubber or clearer for the pressing or other rollers constructed of a metallic
wire in a flat spiral form to bear upon the periphery of the roller substantially as
.described.
2. In a frame for drawing preparing or otherwise treating flax or other fibres
a rubber or clearer for the front drawing or other rollers constructed of a U or
trough shaped piece or strip of thin brass or other metal substantially as described.
3. A rubber or clearer for the rollers of machines for treating flax or other
fibres constructed. of inetallic wire in spiral form substantially as described and
shown with reference to Figs. 1 2 3 and 4 of the accompanying drawings.
4. A rubber or clearer for the rollers of machines for treating flax or other
fibres constructed of U or trough shaped metal substantially as shown and described
with reference to Figs. 12 and 5 of the accompanying drawings.
