Improvements in Means for Cleaning the Revolving Rubbers Used
in Drawing and Roving Frames for the Preparation of Flax or
other Fibrous Materials.
I THOMAS WATSON of Milfort Mill Belfast Ireland Engineer do hereby declare
the nature of this Invention to be as follows :-
My Invention has for its object to provide in connection with drawing and roving
frames for the preparation of flax or other fibrous materials means whereby the
revolving rubbers are efficiently cleaned whilst they are at work.
According to my Invention I mount underneath or in proximity to the revolving
rubber a stationary brush or brushes of wire bristles or any suitable material and
arranged so that it presses or they press against the rubber with a pressure which
can be regulated as desired. As the rubber revolves it comes against this stationary
brush or these stationary brushes and the said rubber has therefore the dirt which it
has gathered removed from it-The brush or brushes is or are so arranged or
mounted that they can be easily cleaned and be put into or taken out of the frames
as desired.

1 THOMAS WATSON of Milfort Mill Belfast Ireland Engineer 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 has for its object to provide in connection with drawing and roving
frames for the preparation of flax or other fibrous materials means whereby the
revolving rubbers are efficiently cleaned whilst they are at work.
According to my Invention I mount underneath or in proximity to the revolving
rubber a stationary brush or stationary brushes of wire, bristles or any suitable
material and arranged so that it presses or they press against the rubbers with a
pressure which can be regulated as desired. As the rubbers revolve against this
stationary brush or these stationary brushes the dirt is removed thereby from the said
rubbers. The brush or brushes is or are so arranged or mounted that they can be
easily cleaned and be put into or taken out of the frames as desired.
And in order that my said Invention may be fully understood 1 shall now more
particularly describe the same and for that purpose shall refer to the several figures
on the annexed sheets of drawings the same letters of reference indicating
corresponding parts in all the figures.
Figures 1, 2 and 3 represent in front elevation and transverse sections looking
from opposite ends of Figure 1 a portion of a roving frame illustrating my Inven-
tion applied thereto and Figures 4 and 5 are similar views to Figures 1 and 3
shewing my Invention as applied to drawing frames. Referring to Figures 1, 2
and 3, A are the revolving rubbers and B the boss roller against which the rubbers A
are forced by spring C acting on collars or brackets D attached to rods E which
bear against the spindle F carrying the rubbers A. In bearings in the brackets D is
mounted a rod or bar G upon which are fitted sockets or frames H in which brushes I
are fixed by any suitable means that will permit of them being readily removed for
renewal when required. The rod or. bar G is provided with a lever or handle K by
means of which the bar may be turned in its bearings on the brackets D so as to
cause the brushes I to come into contact with the revolving rubber A as shewn in
Figure 2 to clean the rubbers when the machine is at work, which brushes when
required or when the machine is not at work are capable of being turned by means
of the handle K out of contact with the rubbers into the position shown in Figure 3
in which position the dirt which has collected on the brushes from the rubbers may
be removed therefrom by any suitable means.
may be adjusted on the rods E to regulate the pressure of the brushes on the

rubbers A.

page_text: In applying my Invention to drawing frames I prefer to mount the rod or bar G
which carries the brushes I in brackets D¹ fixed to the underside of the sliver plate L
as shewn in Figures 4 and 5, the bar or rod G being provided with a handle K as in
the previously described arrangement for bringing the brushes into the position shewn
in Figure to act on the revolving rubbers A to clean them or into the position
shewn in Figure 5 for the purpose of cleaning the brushes from the dirt removed
from the revolving rubbers. The pressure of the brushes I against the rubbers may
be regulated by adjusting the position of the bracket D'.
Having now particularly described and ascertained the nature of my said invention
and in what inanner the same is to be performed I declare that what I
claim is :-
:-
1. In drawing and roving frames employed in the preparation of flax or other
fibrous materials, an adjustable brush or adjustable brushes fitted to the machine for
the purpose of cleaning the revolving rubber when the machine is at work substantially
as herein before described with reference to the accompanying drawings.
2. In drawing and roving frames or machines a brush or brushes capable of being
turned into position for cleaning the revolving rubber when the machine is at work
and of being turned out of contact with the said revolving rubber into position for
being cleaned from the dirt removed from the rubbers substantially as hereinbefore
described with reference to the accompanying drawings.
