Improvements in Machinery Used in the Preparation of Flax,
Hemp, and other Fibres.
JAMES WALLACE Junior 15 Brookhill Avenue, Belfast, Ireland Mill Manager
do hereby declare the nature of this invention to be as follows:-
It relates to the "Rubbers" used in keeping in a clean condition the bosses of
machinery used in the preparation of flax, hemp, and similarly manufactured materials.
The rubbers as at present constructed allow of dirt leaving them, thus making dirty
yarn.
I propose to obviate this by a rubber that will retain dirt, and which, when
requiring cleaning, will enable the operative to remove it for that purpose without
allowing any dirt to leave it.
My invention relates principally to the cleaning of the "Retaining or Back shafts"
and "Delivery Rollers," but may be used elsewhere if desired. It consists of a strip
23 as used at
of wood, metal, or other suitable material, similar to "Dead Rubbers
present, to which is fastened-by hinges or other convenient means--one or more
slips of wood, or other suitable material, with flannel attached, which are kept in
required position by a spring, balance weight, or equivalent device.
While the frame is working the rubber is used in the same manner as an ordinary
"Dead Rubber." When requiring cleaning, the movable slip, on being pressed by
attendant against the main portion of rubber, grasps the dirt, thus enabling it to be
removed without danger to material.
prefer the movable slips to work with a circular motion but I may cause it to
work in a straight line or otherwise.

I JAMES WALLACE Junior of 15 Brookhill Avenue, Belfast Ireland, Mill Manager,
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 —
My invention relates to machines or apparatus for the preparation of flax, hemp
and other fibrous materials.
The "rubbers" employed for cleaning the bosses or rollers of such machines as
hitherto constructed permit of the dirt and loose fibres collected thereby leaving or
dropping from the same when they are being removed for cleansing purposes and
thus producing dirty yarn.
The object of my said invention is to obviate the above defect and to provide a
rubber that will retain the dirt and loose fibres, and which can be removed by the
operator when required for cleansing purposes, without allowing any of the said dirt
or loose fibres to leave it.
In carrying my said invention into practice I prefer to provide the rubber with a
strip of wood or other suitable material hinged or pivoted to the dead or ordinary
rubber, and provided with a suitable spring to retain the same in its normal position
that is to say out of contact with the boss or roller on which the rubber is acting.
My said invention relates more especially to rubbers for cleaning the retaining
bosses or rollers, or back shafts, and the delivery bosses or rollers of machines for
preparing flax hemp and other fibres. My said invention may however be advantageously
employed in other parts of the said machines.
In the accompanying drawing I have shown how my said invention can be con-
veniently and advantageously carried into practice.
Figure 1 is a front elevation and
Figure 2 is a side elevation of my improved rubber showing the strip of wood or
other material in its normal or clevated position.
Figure 3 is a front elevation, and
Figure 4 is a side elevation showing the strip of wood or other material in the
position it assumes when pressed down by the operator to grasp the fly or dirt.
Figure 5 is a side elevation showing the position of the improved rubbers relative
to the bosses or rollers of the machine or apparatus to which they are applied.
Like letters indicate corresponding parts throughout the drawing.
A is the ordinary dead rubber, B is the Jockey roller of a machine for preparing
flax, hemp or other fibres, CC are the retaining rollers thereof.
a is a strip of wood, metal or other suitable material. The strip a is attached to the
ordinary dead-rubber A by means of hinges or otherwise, so that the said strip a will
pivot upon the ordinary dead rubber A. The strip a is provided moreover with

page_text: strips of flannel or other suitable material, and with a spring d to retain the same in
its normal position as shown in Figures 1, 2 and 5. The spring d is attached to the
ordinary dead rubber A and to the strip a by means of staples e or in any other
suitable manner.
The operation of my improved rubber is as follows, that is to say when the
apparatus is working the rubber is employed in a similar manner to the ordinary dead
rubber. When it is desired to clean the rubber the strip a is pressed down by the
attendant against the ordinary dead rubber A, and seizes or grips the dirt or fly
between the said strip a and the ordinary or dead rubber A which can then be removed
for cleansing purposes without the said dirt or fly dropping therefrom upon the yarn.
I thus provide advantageous means for removing the dirt or fly without danger to the
material.
It is obvious that I can somewhat modify the construction of my improved device
without departing from the nature of my said invention. For instance I can form the
hereinbefore described stripa in any convenient number of parts or sections and instead
of the spring herein before described I can employ a balance weight or other suitable
means for keeping the same in the required position. I sometimes morcover construct
the said strip a so that it may be caused to slide in suitable grooves or guides upon
the ordinary dead rubber to and from the boss or roller which it is desired* to
clean.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed I wish it understood that
claim-
First. The combination, with a rubber for the purpose above specified, of a device
whereby the dirt or "fly" collected by the said rubber may be seized and held during
the removal of the rubber, substantially as described.
Second. The improved device comprising the strip of wood or other suitable material
connected to the rubber by hinge-joints or otherwise substantially as described with
reference to the accompanying drawing for the purpose specified.
