PROVISIONAL SPECIFICATION.
Improvements in or connected with Frames for Spinning Flax and
similar Fibres.
I, JOSHUA VALENTINE EVES, of The Forth River Mills, Falls Road, Belfast,
in the County of Antrim, Ireland, Mill Manager, do hereby declare the nature of
this invention to be as follows:-
This invention relates to wet spinning frames in which flax and similar long
stapled fibres are spun into yarn' and is designed with the object of obviating the
necessity which at present exists of applying a great pressure to the back
drawing rollers, by applying to or increasing the tension of the rove before entering
between the rollers.
It consists essentially in the application of a supplementary pressing or jockey
roller to the ordinary pressing roller round which the rove is passed thereby
greatly increasing the bite between the rollers and obviating the necessity for so
great an amount of weight being applied to the rollers.
In carrying out the invention I mount over the pressing rollers and preferably in
contact therewith a supplementary pressing or jockey roller which runs loosely
over the top roller, or weight may be applied thereto. The jockey roller is mounted
in and free to slide in guides carried by the bush of the ordinary top pressing
roller. The rove is passed over the top of the jockey roller and round between it
and the top pressing roller and then between the two pressing rollers as usual
thereby greatly adding to the bite of the rollers upon the rove to prevent pulling
through or slipping of hard fibres and the consequent defects which are known as
"undrawn rove or slips."
By this invention I gain considerable advantage in the working of the machines
and in the quality of the yarn produced. Instead of the extraordinary pressure at
present applied to the back drawing rollers to prevent occasional slips due to hard
strong fibres the rollers may be worked with a minimum pressure and smaller
diameters may be used. The rove is fed into the rollers in a perfectly even manner
with uniform strain and the tension put upon the rove before entering the rollers
prevents the strong fibres pulling it forward, though the individual fibres are pulled
through or are broken. Thus with less wear and tear a better yarn is produced as
the occasional slips found in strong fibre yarn are completely eliminated.

1, JOSHUA VALENTINE EVES, of The Forth River Mills, Falls Road, Belfast,
in the County of Antrim, 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 :-
This invention relates to wet spinning frames in which flax and similar long
stapled" fibres are spun into yarn and is designed with the object of obviating the
necessity which at present exists of applying a great pressure to the retaining, or
"top" pressing rollers or of applying to or increasing the tension of the rove before
entering between the rollers.

The invention will be fully described with reference to the accompanying
drawings in which one stand of rollers is illustrated with my invention applied
thereto.

The rail or beam A, the stand B, the

"
bottom or drawing rollers C C¹, the
top or retaining rollers D D¹, the roller journals cd, the weight wire E, the
weight lever F, and the trough G are all of any usual or ordinary form or
construction.
Upon the ordinary top pressing roller D¹ of the retaining rollers and in rolling
contact therewith I mount a supplementary pressing or jockey roller H. This
roller H is maintained in position upon the top of the ordinary pressing roller
by an extension of the ordinary "top slide" I which is made fast to the "saddle" K.
The ordinary top pressing roller is journalled in the sliding piece J the seating of
which rests on an inclined plane or face of the top slide 1. When pressure is
applied to the saddle K by the weight wire E the sliding piece J with its roller D'
is forced upwards and the bite between the rolling surfaces of D¹ and H is made
great, whilst the pressure of the ordinary top pressing roller D' against the
retaining roller D is not reduced.
"
The top slide" I is held in the desired position by the screw i to suit the
"reach or distance between the rollers D and C as is usual.. The sliding piece J
carrying the pressing roller D¹ is provided with a lug j through which a wire fl
affixed to the "top slide" I freely passes and serves to keep these parts together
when they are not in working position.
The rove passes from the trough G over the top of the jockey roller H and
round between it and the top pressing roller D' then between the two pairs of
rollers D D and C C' in the ordinary way. The rove is thus held by two bites
instead of by one as is usual and thus is prevented the pulling through or slipping
of hard fibres and the consequent defects which are known as "undrawn rove
"slips."
or
By this invention I gain considerable advantage in the working of the spinning
machines and in the quality of the yarn produced. Instead of the extraordinary
pressure at present applied to the saddle to obtain a certain amount upon the top
roller to lessen the number of slips due to hard strong fibres the rollers may be
worked with a minimum pressure thus allowing rollers smaller in diameter to be
used. The rove is fed between the rollers in a perfectly even manner and the
extra bite put upon the rove before entering the bite of the rollers D D¹ prevents
the strong fibres in the rove pulling it forward. Thus with less wear and tear a
better yarn is produced as the occasional "slips" found in strong fibre yarn are
eliminated and shorter "reaches may be employed without fear of "undrawn
rove."
"
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 machines for spinning flax or similar long staple fibres the combination
with the retaining rollers of a supplementary pressing or jockey roller mounted in
rolling contact with the top pressing roller round which the rove is passed
substantially as and for the purpose described.

page_text: 2. In machines for spinning flax and other similar fibres the combination with
the retaining rollers of a supplementary pressing or jockey roller H and an
adjustable top slide I having an inclined face upon which the sliding piece J moves
and carries the pressing roller D' into contact with the jockey roller H substantially
as described.
