AN IMPROVEMENT IN WET SPINNING FRAMES
Year: 1884

page_text: I JOHN ERSKINE of Wolfhill, Belfast, Co Antrim Mill Manager do hereby declare
the nature of my invention for "AN IMPROVEMENT IN WET SPINNING FRAMES,"
to be as follows:-
:-
This invention relates to a novel application of cleaning rollers to the drawing
rollers of wet spinning frames, the object being to keep the surfaces of the drawing
rollers clean-and free from the accumulation of short fibres or glutinous matter.
Means for attaining this object was the subject of an invention for which
Letters Patent No 4056 were granted to the present inventor September 20th 1881
and it was secured in great measure, but not with such perfection as to preclude
the use of the present invention especially upon frames for making high class
yarns it being in such case desirable to keep the drawing rollers perfectly free from
any inequalities or dirt on their surfaces.
I now propose to apply to the underside of the bottom drawing rollers, cleaning
rollers which will run in contact therewith.
These cleaning rollers are made of any suitable material and the surfaces which
come in contact with the bottom drawing rollers are covered with flannel or other
suitable material. The bottom cleaning rollers are held in contact with the bottom
drawing rollers (which are usually made of brass and fluted) by being mounted on
weighted levers or equivalent supports which will admit of the ready removal of
the rollers for cleaning.

I JOHN ERSKINE of Wolfhill, Belfast, Co Antrim, Mill Manager, do hereby
declare the nature of my invention for AN IMPROVEMENT 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 relates to a novel application of cleaning rollers to the drawing
rollers of wet spinning frames, the object being to keep the surfaces of the drawing
rollers clean and free from the accumulation of short fibres or glutinous matter.
Means for attaining this object was the subject of an invention for which
Letters Patent No 4056 were granted to the present inventor September 20th 1881,
and it was secured in great measure, but not with such perfection as to preclude
the use of the present invention, especially upon frames for making high class yarns,
it being in such case desirable to keep the drawing rollers perfectly free from any
inequalities or dirt on their surfaces.
I now propose to apply to the underside of the bottom drawing rollers, cleaning
rollers which will run in contact therewith.
These cleaning rollers are made of any suitable material, and are held in contact
with the bottom drawing rollers (which are usually made of brass and fluted) by
being mounted on weighted levers or equivalent supports, which will admit of the
ready removal of the rollers for cleaning.
In the accompanying drawing-
Fig. 1 shows in partial side section a wet spinning frame with my invention
applied thereto, and
.
Fig. 2 is a front view of one of the cleaning rollers and the weighted arms by
which it is carried detached from the frame.
In these figures a a are the cleaning rollers carried by hollow axles for lightness,
in preference to solid axles. They are covered with flanuel or other suitable
material such as felt, leather, rubber, or they may be formed with brushing surfaces,
the object being to enable them to pick up the short fibres and prevent the
accumulation of glutinous inatter on the bottom drawing rollers. b indicates these

rollers serve to rotate the cleaning rollers a by friction of contact therewith. The
cleaning rollers may, however, if thought desirable, be driven independently and at
a different surface speed. They are mounted on the ends of, and held up to their
work by pairs of weighted arms a¹ having their fulcrum in brackets pendent from
a transverso rail of the main framing. When it is desired to remove the cleaning
rollers a from the machine, it will only be necessary for the attendant slightly to
depress the short arms of the weighted levers and the rollers may then be lifted off
their bearings.
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 to the bottom drawing rollers of wet spinning frames of cleaning
rollers in the manner and for the purpose herein described.
