PROVISIONAL SPECIFICATION.
An Improvement in Wet Spinning Frames for Flax, Hemp, and
such like Fibres.
JOHN BARBOUR of Grove Mill Belfast County Down Ireland Flax Spinner do
hereby declare the nature of this invention to be as follows:-
The object of this invention is to make such an arrangement in the water troughs
of wet spinning frames that a greater length of rove can be immersed at the same
time so that the water in the trough-which is employed for softening the gum
that joins the fibres together-can be used without being heated artificially.
By this increased length of rove being immersed the gun is sufficiently softened to
allow the fibres to draw off each other and yet not to such an extent as to dissolve and
abstract or remove the gum and mix it with the water which is the case when hot
water is employed to soften the gum.
This arrangement consists of a series of grooved rods or adjacent pullies carried in
the water trough but free to revolve round these pullies or grooved rods the rove is
wound or belayed a sufficient number of times to give each part of the rove a
sufficient time in the water to soften the gum in the rove during its passage through
the water from the rove bobbin to the drawing rollers.
Dated this 6th day of September 1888.

COMPLETE SPECIFICATION.
An Improvement in Wet Spinning Frames for Flax, Hemp, and
such like Fibres.
JOHN BARBOUR of Grove Mill Belfast County Down Ireland Flax Spinner 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:-
The object of this invention is to make such an arrangement in the water troughs
of wet spinning frames that a greater length of rove can be immersed at the same
time so that the water in the trough (which is employed for softening the gum that
joins the fibres together) can be used without being heated artificially.
By this increased length of rove being immersed the gum is sufficiently softened
to allow the fibres to draw off each other and yet not to such an extent as to
dissolve and abstract or remove the gum and mix it with the water which is the
case when hot water is employed to soften the gum.
The arrangement is illustrated in the sheet of drawings herewith. Fig. 1 is a section
of an ordinary water trough for wet spinning frames and Fig. 2. is a top view of the
same with the arrangement exposed.
This arrangement consists of a series of grooved pullies (a) free to revolve upon
rods (b) a pair of pullies (a) to each line of rove (c). The line of rove (c) in its
passage from the rove bobbin (c¹) to the drawing rollers (d) is passed round the
grooves in the pullies (a) in the direction indicated by the arrows a sufficient number
of times to give each part of the rove (c) a sufficient time. in the water to soften
the gum in the rove during its passage through the water from the rove bobbin (e¹) to
the drawing rollers (d).
The grooves in the pullies (a) are all the same diameter at the bottom but have
different diameters of flanges to make it easier for the attendant when passing round
an end

page_text: The grooved pulleys (a) are made of wood or other light material and are bushed
so as to turn freely upon the rods (b).
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 grooved pullies described and illustrated in the water troughs
of wet spinning frames for the purpose of immersing a greater length of rove
during its passage through the water.
