TAYLOR BURROWS Engineer, 88 Upper Keunington Lane, S.E. DICK
RADCLIFFE Horticultural Decorator 56 Gloucester Crescent, Regent's
Park, N.W. do hereby declare the nature of this invention to be as follows:-
In spinuing frames used for the above fibres the roving is fed through slowly
revolving rollers, & carried forward to drawing rollers, which move quicker than
the retaining rollers, & so draw the fibres of which the roving is composed which
is twisted by the spindle, & wound on the spool or bobbin.
There is a slight twist in the roving, & various devices are in use to prevent the
fibres being drawn away irregularly from the roving, by keeping the twist in the
said roving
In flax, hemp, & jute spinning on the dry frame, the roving is made to pass
over & against a friction plate.
In wool, & silk waste spinning the roving is carried forward from the back to the
front drawing roller over 2 or 3 carrier rollers having a light top roller pressing
in the roving
All these various modes of spinning leave the thread or yarn very hairy, which
is an objection where brilliancy is desired.
The aim of our present invention, is to spin ramie, rhea, china grass, or other
fibres wet, so that the yarn will be stronger, smoother & brighter than by the dry
method.
We obtain this result, by passing the roving through a trough of water pure,
or having some ingredient in it either to aid its brilliancy, or to tint or dye it
during the spinning.
The roving leaving the bath of cold or warm liquid, passes through the back
rollers, & is carried over 2 or more carrier rollers having a V groove turned in
them these rollers may be slightly higher than the feed & drawing rollers so that
the roving lays at the bottom of these grooves, & is thus prevented untwisting, the
front rollers drawing away the fibre in a wet state, the spindle then twisting the
thread, & winding it on the bobbin. We thus obtain a smooth even yaru, which
is the object desired.

Improvements relating to the Spinning of Ramie, Rhea, China
Grass, or other Fibres.
We, TAYLOR BURROWS, Engineer, 88 Upper Kennington Lane, London, S.E.
and DICK RADCLYFFE, Horticultural Decorator, 56 Gloucester Crescent, Regent's
Park, London, N.W. do hereby declare the nature of this invention and in what
[Price 8d.1

page_text: manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
Heretofore in spinning frames used for fibres such as rhea, china grass, or ramie,
wool, silk waste, flax, hemp and jute the roving is fed through slowly revolving
rollers and carried forward to drawing rollers which move quicker than the
retaining rollers and so draw the fibres of which the roving is composed which is
twisted by the spindle and wound on the spool or bobbin.
There is a slight twist in the roving and various devices are in use to prevent
the fibres being drawn away irregularly from the roving by keeping the twist in
the said roving and for this purpose in flax hemp and jute spinning on the dry
frame the roving is made to pass over and against a friction plate while in wool and
silk waste spinning the roving is carried forward from the back to the front drawing
roller over 2 or 3 carrier rollers having a light top roller pressing on the roving.
These various modes of spinning as heretofore do not leave the thread or yarn
very smooth or even on the surface thereof but on the contrary same remain more
or less "hairy" which is an objection especially where brilliancy is desired.
Now the object of our present invention is primarily to spin china grass, rhea,
or ramie (although other fibres to which our invention is applicable may also be
similarly spun) wet so that the yarn we thus produce will be very smooth and even
on its surface and having many advantages particularly in the case of china grass
rhea or ramie when thus spun.
And in order to fully explain our present invention we will proceed to describe
same with reference to the drawings hereunto annexed.
Fig. 1 is a diagrammatic side view showing our improvements.
Fig. 2 is a frout view-i.e. looking in the direction of the arrow z.
According to this invention we pass the roving A- -as same comes from the
bobbin B on the spinning frame through a trough bath or vessel C of any suitable
shape mounted in the spinning frame and containing liquid for instance pure water
(hot or cold) or any suitable chemical or ingredient therein or any other suitable
liquid mixture or solution to wet or moisten the fibre and add to its brilliancy and
also if desired to tint or dye it or otherwise treat it during spinning.
The roving is caused to pass under a rod roller or rail D or other guide in said
trough or vessel C to ensure immersion in said bath and thence is passed between
the back or feed rollers E and is carried on over carrier rollers F G H having
V-shaped circumferential grooves therein F¹ G' H' respectively according to our
present invention in the bottom of which grooves the rovings respectively lie.
These carrier rollers (2, 3, or any suitable number of which may be used for
instance three rollers such as F G II) are mounted slightly higher than (i.e. slightly
above) the direct straight line between the back or feed rollers E and the drawing
rollere I advantageously in the form of a curve or arch whereby the strain put on
the roving by the drawing rollers forces or draws the roving down to the narrow-
most bottom part of the said V-shaped groove and thereby the roving is as it were
wedged therein and consequently any untwisting of the roving is prevented or
practically prevented while at same time the rovings can freely run (in the said
V-grooves) over said carrier rollers F G and H which latter may be mechanically
revolved at the same or different peripheral speed as the feed rollers or said
V-grooved carrier rollers may be "idle "rollers.
By this means also we dispense with the use or necessity of top rollers over the
carrier rollers F G and H.
The drawing rollers operate as heretofore to draw away the fibre in this wet
state and same is then twisted into a thread or yarn and wound on the bobbins in
the usual or any suitable manner.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
In spinning fibres of the character described-a spinning frame provided with a

page_text: bath of any suitable liquid through which bath the rovings are led before passing
through the feed rollers in combination and acting in conjunction with carrier
rollers having V-shaped circumferential grooves therein and said carrier rollers
arranged in a curve or arched form between the said feed rollers and the drawing
rollers substantially in the manner and for the purposes hereinbefore described.
