Improvements in Frames for Spinning Flax and similar Fibres.
I JOSHUA VALENTINE EVES of Forth River Mill 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 frames in which flax and other similar fibres are spun
by the wet process and is designed with the object of obtaining a very short
"reach
or distance between the drawing and retaining rollers without reducing
the diameters of the drawing rollers while at the same time the strength and
working surfaces of such parts as most require these essentials are greater than in
the present existing arrangements.
It consists essentially in interposing between the top retaining roller-or &
driving shaft substituted for it-and the drawing rollers, a supplementary retaining
roller of greatly reduced diameter upon which the top pressing roller bears and to
which motion is transmitted from the driving roller or shaft at one two or more
places along the length of the frame, whereby the "reach" between the rollers
can be reduced while the "nips" of the rollers are maintained in line.
In carrying out the invention I prefer to keep the drawing roller with its.
wooden pressing roller as large as possible as is at present the custom and also to
maintain the present retaining roller but to use it as a driving roller to drive a
supplementary retaining roller reduced to a size or diameter that is not usual nor
indeed possible in the present arrangement of spinning frame and interposed between
it and the drawing rollers.
To the retaining roller I transmit motion from the driving roller at several
places along the length of the frame and not merely at the end of the roller as is
customary and I am thus enabled to use a retaining roller of very greatly reduced
diameter without straining or twisting it. The method I at present prefer
to employ is to make the retaining roller in lengths of say two bosses and allow
the fluted faces of the bosses to engage with corresponding flutes on the driving.
roller or fluted driving shaft.
The retaining rollers may however be made of any desired length and may be
geared or connected with the driving shaft by gear wheels or other suitable means
at intervals along its length.
It will be evident that instead of rotating the driving roller or shaft in the
reverse direction to what is customary a carrier roller or wheels may be employed.
to convey the motion and it is also to be understood that two or more supplemental
rollers may be employed if desired to convey the motion from the driving to the
retaining rollers.
The driving roller or shaft may be carried in the usual sliding bush of the
double stands so that the distance between it and the bottom roller can be easily
altered and the position of the independent or supplementary retaining roller and its
pressing roller are then adjusted to suit the length of reach.
The driving roller or shaft may be placed in any other convenient position such
as above or in front of the retaining rollers or above the top pressing roller with
suitable bearings for supporting it and means for adjusting its position. If desired
the driving roller or shaft may gear with the pressing roller instead of with the
retaining roller but I consider the former method preferable.
The supplementary retaining roller and its pressing roller are held in position
and the desired weight applied to them by any suitable construction of saddle and
ton alido

and afterwards lead it into the usual bite between the retaining roller and its pressing
roller.

Improvements in Frames for Spinning Flax and similar Fibres.
I, JOSHUA VALENTINE EVES, of Forth River Mill, 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 frames in which flax and other similar fibres are spun
by the wet process and is designed with the object of obtaining a very short
"reach
or distance between the drawing and retaining rollers without reducing
the diameters of the drawing rollers while at the same time the strength and
working surfaces of such parts as most require these essentials are as great or
greater than in the present existing arrangements.
It consists essentially in interposing between the top retaining roller-or a
driving shaft substituted for it-and the drawing rollers, a supplementary retaining
roller of greatly reduced diameter upon which the top pressing roller bears and to
which motion is transmitted from the driving roller or shaft at one, two or more
places along the length of the frame, whereby the." reach" between the rollers can
be reduced while the "nips" of the rollers are maintained in line.
. The invention will be fully described with reference to the accompanying
drawings in which as examples three modifications are shown.
Fig. 1. Transverse section.
Fig. 2. Transverse section of rollers showing a modification the stand being
removed.
Fig. 3. Transverse section of another modification.
The drawing roller A the bottom pressing roller B the stand C and the saddle D
may be constructed as shown or of any ordinary or suitable construction, the
drawing roller A with its wooden pressing roller B being maintained of as large a
diameter as is at present the custom.
I prefer to maintain the ordinary retaining roller E in its present position but I
now use it as a driving roller or shaft and in addition thereto I employ a retaining
roller F of small diameter interposed between it and the drawing rollers A and B
and reduced to a size or diameter that is not usual nor indeed possible in the present
arrangement of spinning frame.
The retaining roller F is preferably made in lengths of two bosses and the fluted
faces of the bosses engage with corresponding flutes on the driving roller or shaft E
so that little or no stress or strain is exerted upon the shaft or spindle of the
roller F.
The retaining roller F may however be made of any desired length and the.
motion transmitted to it at several places along the length of the frame either at
every boss or at two, three or more points instead of at the end of the roller as at
present customary. I am thus enabled to employ a retaining roller of very greatly
reduced diameter without straining or twisting it.
Instead of gearing the flutes in the bosses of the retaining roller E with corre
sponding flutes in the driving roller or shaft E the retaining rollers may-as shown
in Fig. 3-be geared or connected with the driving shaft E by gear wheels e or
other suitable means at intervals along its length.
In Fig. 3. the driving shaft E may run the whole or part of the length of the

page_text: frame being geared by means of the wheels e with the small sized retaining roller F
at the centre or other desired position, E' being a stud or pin for the intermediate
or carrier wheel e¹ or a driving shaft may occupy the position of El running the
length of the frame the top or movable bearings and the studs being altered in
shape to support it.
In Fig. 1 the driving roller or shaft E will rotate in the reverse direction to
what is customary so as to give the proper direction of motion to the retaining
roller F whilst in Fig. 3 when the carrier wheel e¹ is employed to convey the
motion the driving shaft E rotates in the ordinary way and in the same direction
as the rotating roller F.
The driving roller or shaft may as shown in Fig. 1. be carried in the usual sliding
bush H of the double stands so that the distance between it and the bottom or
drawing roller A can be easily altered and with it the position of the independent
or supplementary retaining roller F; its pressing roller G is then adjusted to suit
the length of reach.
The driving roller or shaft E may be placed in any other convenient position
such as above the retaining roller For above the top pressing roller G with
suitable bearings for supporting it and means for adjusting its position. If desired
the driving roller or shaft E may as shown in Fig. 2 be in contact with the top
pressing roller G instead of with the retaining roller but I consider the latter
method preferable.
The supplementary retaining roller F and its pressing roller G are held in
position and the desired weight applied to them by any suitable construction of
saddle D top slide d or stand I.
No specific claim is made in this Patent for the form of stand shown in Fig. 1.
as it forms part of the invention described and claimed in my Patent No. 4702 of
even date herewith it being illustrated herein to show what I at prescut consider
the best method of carrying this invention into effect.
To increase the holding power or bite of the retaining roller upon the yarn I
first introduce the rove between the fluted surfaces of the driving roller or shaft E
and retaining roller F and afterwards lead it into the usual bite between the
retaining roller F and its pressing roller G.
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. A frame for spinning flax or similar fibres provided or constructed with a
retaining roller of small diameter interposed between the present retaining roller
and the drawing roller and driven by the present retaining roller or a shaft sub-
stituted therefor to enable the "reach" or distance between the rollers to be
shortened without reducing the diameter of the drawing rollers or the strength of
the driving parts substantially as described.
2. In a frame for spinning flax or other similar fibres the combination with a
retaining roller of small or reduced diameter of a second roller or driving shaft
running wholly or partly the length of the frame and gearing with the retaining
roller at one or more places throughout its length to reduce the torsion or twisting
strain upon the retaining rollers substantially as described.
