PROVISIONAL SPECIFICATION.
Improvements in Spinning Machinery for Spinning Flax and other
Fibrous Substances.
I, GEORGE HORNER of Clonard Foundry, Falls Road, Belfast, Ireland,
Flax Machine Maker, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the retaining and drawing rollers of spinning machinery
for spinning flax and other fibrous substances and it has for its object to obtain
greater simplicity and efficiency, diminish the friction with which the yarns are
conducted to the bobbins and so ensure better spinning, less waste and cleaner
yarns.
The improvement consists in making the two rollers of each pair of retaining
rollers and likewise those of each pair of drawing rollers fit together in the manner
of a tongue and grooove, by providing the one roller with a circumferential groove
in which the other roller or a circumferential rib thereon fits, the groove which is
very narrow being proportioned to the range of numbers or counts of yarns and to
suit the other proportions of the spinning frame, those of the drawing rollers being
proportionately narrower than those of the retaining rollers to correspond to the
diminution of material caused by the drawing action which takes place between
the retaining and drawing rollers.
Both rollers may be narrowed until little more than mere discs of a thickness and
form consistent with the pressure to be applied to them.
By this improvement less pressure is required for drawing purposes and the
rollers are not so liable, as are the broad faced rollers generally used, to collect
dirt which if taken into the yarn, as frequently happens, makes the yarns nappy.

COMPLETE SPECIFICATION.
Improvements in Spinning Machinery for Spinning Flax and other
Fibrous Substances.
I, GEORGE HORNER of Clonard Foundry, Falls Road, Belfast, Ireland, Flax
Machine Maker, 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 the retaining and drawing rollers of spinning machinery
for spinning flax and other fibrous substances, and it has for its object to obtain
greater simplicity and efficiency and so ensure better spinning, less waste, and
cleaner yarns.
The improvement consists in making the two rollers of each pair of retaining
rollers and likewise those of each pair of drawing rollers fit together at their point
of nip, in the manner of a tongue and groove, by providing the one roller with a
circumferential groove in which fits the edge of the other roller (or of a circum-
ferential rib thereon) the groove which is very narrow, being proportioned to the
'range of numbers" or "counts" of the yarns and to suit the other proportions of
the spinning frame those of the drawing rollers being proportionately narrower than
those of the retaining rollers to correspond to the diminution of material caused by
the drawing action which takes place between the pairs of retaining and drawing

page_text: rollers. Both rollers of each pair may thus be narrowed until they are little more
than mere discs, of a thickness and form consistent with the pressure to be applied
to them. By this improvement, the great expense of renewing wooden or gutta-
percha pressing rollers, which are pressed upon the drawing rollers with considerable
force, is saved and the rollers are not so liable, as are the broad-faced rollers
generally used, to collect dirt which if taken into the yarn, as frequently happens,
makes the yarns nappy.
Reference is to be had to the accompanying drawings, forming part of this
Specification, in which
Figure 1 is a sectional elevation of part of a flax-spinning machine provided with
retaining and drawing rollers constructed according to my invention.
Figure 2 is a plan of two adjacent pairs of rollers, drawn separately and to a
larger scale.
The same letters of reference denote like parts in both figures.
A B are the pair of retaining rollers and CD the pair of drawing rollers between
which the yarn to be spun passes from the hot-water trough E to the flyer F on the
spinning spindle. The main rollers B B of all the pairs of retaining rollers comprised
in the machine, are mounted upon a continuous shaft b through which the several pairs
of rollers are driven in the usual manner, whilst the pressing rollers A A' of each two
adjacent pairs are mounted upon the ends of short shafts a. Similarly, the main
rollers D D of all the pairs of drawing rollers are mounted on a continuous shaft d
whilst the pressing rollers C, C, of adjacent pairs are on the opposite ends of short
shafts call in the usual manner, the pressing rollers A, A, of two adjacent pairs of
retaining rollers B, B, being pressed towards the corresponding main rollers and
the pressing rollers C, C, of two adjacent pairs of drawing rollers being pressed
towards the corresponding main rollers D, D, all by a weighted lever G acting on
the shafts a, through a link h and saddle piece H in the usual way. The rollers
of each pair of retaining rollers and likewise those of each pair of drawing rollers
are fitted to work together as above described, that is to say the one roller has a
circumferential groove in which the edge y of the other roller fits at the point of
nip where the yarn passes through the groove and is nipped between the bottom of
the groove in the one roller and the edge of the other roller.
I have shewn the pressing rollers as grooved and the main rollers as narrowed at
the edge to fit therein but the main rollers might be grooved and the pressing
rollers narrowed to fit therein with equal advantage and my invention therefore
comprises grooving either roller of each pair and making the other roller of the
pair fit in the groove.
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 a machine for spinning flax and other fibrous materials, making the two
rollers of each pair of retaining rollers and likewise those of each pair of drawing
rollers fit together at the point of nip by providing the one roller of each pair with
a circumferential groove in which the edge of the other roller (or of a circum-
ferential rib thereon) fits substantially as and for the purpose specified.
2. In a spinning machine, making the retaining and drawing rollers in the form
of narrow discs the two rollers of each pair fitting together at the point of nip by
the edge of the one roller entering a circumferential groove in the other roller as
specified.
