PROVISIONAL SPÉCIFICATION.
A New Arrangement for Regulating the Position of Retaining
Rollers in Spinning Frames for Flax or other Fibres.
GEORGE HUNTER of 153 Crumlin Road Belfast Ireland Mechanic do hereby declare
the nature of this invention to be as follows:-
This arrangement for regulating the position of retaining rollers in spinning frames
is specially adapted for spinning frames wherein the back or retaining rollers are
carried in moveable or sliding bushes.
The usual method of regulating the reach or distance between the back or retaining
rollers and the front or drawing rollers being to move each of the sliding bushes
which carry the back roller by means of a screw each sliding bush having to be
moved separately.
This new arrangement consists in dispensing with the regulating screws to each
sliding bush for the back roller and using instead a flat bar which extends the entire
length of the roller and passes through the stands which carry the sliding bushes.
Underneath the sliding bushes are projections which fit into diagonal slots in the
flat bar so by moving the bar endwise the sliding bushes are caused to simultaneously
approach or recede from the front roller and thus alter the reach.
The flat bar with diagonal slots is retained in one position or moved endwise by
means of an adjusting screw at one end.
By moving the sliding bushes in this manner the usual "lining up" of the back
roller bushes after every change of reach is avoided and increased facilities are
afforded for altering the frame to suit the different fibres being spun.

COMPLETE SPECIFICATION.
A New Arrangement for Regulating the Position of Retaining
Rollers in Spinning Frames for Flax or other Fibres.
GEORGE HUNTER of 26 Avoca Street Clifton Park formerly of 153 Crumlin Road
Belfast Ireland Mechanic 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 arrangement for regulating the position of retaining rollers in spinning frames
is specially adapted for spinning frames wherein the back or retaining rollers are
carried in moveable or sliding bushes.
The usual method of regulating the reach or distance between the back or retaining
rollers and the front or drawing rollers being to move each of the sliding bushes
which carry the back roller by means of a screw each sliding bush having to be
moved separately.
This new arrangement consists in dispensing with the regulating screws
to each sliding bush for the back roller and using instead a flat bar which extends
the entire length of the roller and passes through the stands which carry the sliding
bushes.
This arrangement is illustrated in the drawing herewith in which fig. 1 is a section
of the drawing rollers of an ordinary wet spinning frame and shewing the stand for
carrying them fig. 2. is a top view of one head of rollers fig. 3. is an edge view of
the flat bar and the screw for moving it end wise.
In this new arrangement for regulating the position of the retaining rollers (a) in
spinning frames the sliding bushes (a¹) which carry the retaining rollers (a) have

page_text: underneath projections (a²) which fit into diagonal slots (6) in a flat bar (6¹) so by
moving the bar (6) end wise the sliding bushes (a¹) are caused to simultaneously
approach or recede from the front roller (c) and thus alter the reach.
The flat bar (6) with diagonal slots (b) is retained in one position or moved endwise
by means of an adjusting screw (d) at one end.
By moving the sliding bushes (a) in this manner the usual "lining up" of the back
roller bushes after every change of reach is avoided and increased facilities are
afforded for altering the frame to suit the different fibres being spun.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
"The arrangement of diagonal slots in a sliding bar as described for regulating the
position of retaining rollers in spinning frames for flax or other fibres.
Dated this 23rd day of January 1890.
