PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Drawing Fibres.
I, WILLIAM THOMPSON, of Larkfield, Rawdon, Leeds in the County of
York, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
-
This invention relates to further improvements in machinery for purpose afore-
said for which Letters Patent 13913 dated 4th September 1859 were granted to
the present Applicant.
In the Specification referred to there is described a series of rollers and two
elastic bands and such give practical and good results.
I have found however that one india rubber band and three spiked rollers and
a guide or stretching roller will work satisfactorily and in some cases in lieu of
the spiked rollers or in lieu of one or more of such I substitute a plain iron roller
and an india rubber band. Or the spiked or studded rollers in lieu of having an
india rubber band working over them may be coated or covered with india rubber
and work in conjunction with a single elastic band.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Drawing Fibres.
I, WILLIAM THOMPSON of Larkfield, Rawdon, Leeds, in the County of York,
Manufacturer, 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 further improvements in machinery for purpose afore-
said for which Letters Patent 13913 dated 4th September 1889 were granted to
the present Applicant.
In the Specification referred to there is described a series of rollers, and two
elastic bands, and such give practical and good results.
I have found however that one india rubber, or elastic band, and three spiked
rollers, and a guide or carrier roller will work satisfactorily, and in some cases in
lieu of the spiked rollers, or in lieu of one, or more of such, I substitute a plain
iron roller, and an india rubber or other clastic band. Or the spiked, or studded
rollers in lieu of having an india rubber band working over them may be coated or
covered with india rubber, or leather, and work in conjunction with a single elastic
band.
Such being the nature, and object of my said invention the following is a com-
plete description of same, reference being made to the accompanying drawings in
which :-
Fig. 1. is a side elevation of my improved apparatus for purpose aforesaid.
Fig. 2. is a front elevation of Fig. 1.
Fig. 3. is a side elevation of my improved apparatus for purpose aforesaid the
gear wheels being removed.
Fig. 4. is a sectional end elevation of the spiked drawing, and carrier, or guide
rollers, and elastic band.
Fig. 5. is a similar view to Fig. 4. but only one guide, or carrier roller is
employed.

page_text: Fig. 6. is a similar view to Fig. 5 but the drawing rollers are shewn coated, or
covered with india rubber, or leather, and working in conjunction with a single
elastic steel band.
Fig. 7. is a plan view of a form of steel band which I have found to work in
practice.
According to this my present invention I employ one india rubber, or other
elastic band 1 and three spiked rollers 2. 3. 4. and guide or carrier rollers 5. 5.
(see Figs. 1. 2. 3. and 4.) or a single guide, or carrier roller 5. (see Figs. 5 and 6.)
which have found in practice to give good results. The rollers 2. 3. 4 and 5 are
carried in the end frames 6. 6 and one of the rollers-say 3. is adjustable by means
of the strap 7 and screws 8. 8. The rollers are geared together as shewn by
Fig. 1. in such a manner that the roller 3 runs a little faster than the roller 2, and
the roller 4 a little faster than the roller 3 the speeds being regulated according to
the length of staple of the fibre being operated upon, so that the requisite drawing
out, or drafting of the fibre is attained through the variation in surface speed of
the rollers, and elastic band. The entrance of fibre is between the rollers, at the
point 9 and its exit at 10, and it will be obvious that the draft may be varied as
the surface speed of the rollers, and endless band is changed.
The spiked, or studded rollers 2. 3. 4 may consist of pins driven into, or otherwise
fixed around the circumference of the rollers, or a covering of wire cards set in a
felt, or other thick foundation may be employed, but I do not confine myself to
any special form, or kind of pin, so long as the rollers are provided with pointed,
spiked, porcupine, or roughened surfaces, nor do I confine, or limit myself to the
use of three of such rollers.
In some cases in lieu of employing spiked rollers I substitute plain iron rollers,
and have found that the frictional contact between the rubber band 1 and the
several rollers is sufficient to draw the fibre as herein described.
Or the spiked, or studded rollers 2. 3. 4. 5. in lieu of having an india rubber
band such as I working in connection with them, may be coated with india rubber,
or covered with leather as at 11 (see Fig. 6.) and work in conjunction with the
clastic steel band a part of which is shewn by Fig. 7. and is composed of steel wire
twisted and made as ordinary.
The carrier, or guide rollers 5. 5. are simply for directing the course of the band 1
which band being stretched in passing over the rollers 2. 3 and 4 recovers itself, or
contracts between these rollers 5. 5.
Having now particularly described and ascertained the nature and object of my
said invention, and in what manner the same is to be employed, I declare that
what I claim is :-
1. The spiked rollers, plain guide, or carrier roller or rollers, and an elastic band
of india rubber, all in combination and as described for purpose set forth, and as
shewn by Figs. 1. 2. 3. and 4 of the accompanying drawings.
2. The combination of an elastic band with plain drawing rollers, and guide, or
carrier rollers such as described, and for purpose set forth.
3. Rollers coated with india rubber, or covered with leather, and having an
elastic band, india rubber, or steel wire band, as described, and illustrated by Fig. 6
and for purpose herein set forth.
