Complete Specification Left, 4th June, 1890-Accepted, 26th July, 1890
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 improved apparatus for the drawing of fibres, being specially
applicable to dealing with fibre of short staple, and may be used in combination with
a mule or spinning frame, or the fibres so drawn may be twisted from the improved
appliance direct.
The improved apparatus consists of a series of studded rollers, over and under which
are passed two endless bands preferably of india-rubber or elastic band or web, these
work one over the other, so as to confine and carry the fibre between them until
arriving at the delivery end when they are diverted by guide rollers so as to separate
or open the bands for the delivery of the fibre the bands return to the leading in or
starting rollers.
The studded rollers may be of metal or hard wood and are provided with top or
weighting rollers.
The relative speed of the rollers being such as to give the required draft.
I have obtained satisfactory results from the use of cog wheels and the elastic bands,
but I prefer the studded rollers, as herein first mentioned.
Dated this 3rd day of September 1889.

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 improved apparatus for the drawing of fibres, being
specially applicable to dealing with fibre of short staple, and may be used in combination
with a mule or a spinning frame, or the fibres so drawn may be twisted from the
improved appliance direct.
The improved apparatus consists of a series of suitable rollers over and under which
are passed two endless bands preferably of india-rubber or elastic band or web, these
work one over the other so as to confine and carry the fibre between them until
arriving at the delivery end when they are diverted by guide rollers so as to separate
or open the bands for the delivery of the fibres the bands return to the leading in or
starting rollers.
The studded rollers may be of metal or hard wood and are provided with top or
weighting rollers.
The relative speed of the rollers being such as to give the required draft.
I have obtained satisfactory results from the use of cog wheels and the elastic
bands, but I prefer the studded rollers as herein first mentioned.
Such being the nature and object of this my said Invention, the following is a
complete description of same reference being had to the accompanying drawings which
form part of this Specification in which :-
Fig. 1 is an end elevation of apparatus for purpose aforesaid.
Kia 2 is a front elevation of Fig 1

page_text: Fig. 3 is a cross section.
Fig. 4 is an elongated view of part of a roller and band.
Fig. 5 illustrates a studded roller whereon the points of wire cards serve as the
studs or pins.
At 1. 1. are the end frames or brackets which carry the axles of the three studded
rollers 2. 3. 4 geared together as shewn at a. b. c the wheel 3 being adjustable by
means of the strip 5 and screws 6. 6. The two rollers 6 and 7 are guide rollers, 8
and 9 are two endless bands preferably of india rubber which pass over and under
the several rollers as shewn in the drawings. The rotation of the rollers 2. 3. 4 is
varied that is to say-roller 3. runs a little faster than roller 2, and roller 4 a little
faster than roller 3, so that the requisite drawing out or drafting of the fibre is attained
through the variation on surface speed of the rollers bands 8 and 9. The entrance of
fibre is between the rollers bands at the guide roller at 6 and its exit at 7, and it
will be obvious that the draft may be varied as the surface speed of the two endless
bands is changed.
The studded rollers 2. 3. 4 may consist of pins driven or otherwise fixed in the
end around the circumference of the roller or a roller 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 2. 3. 4 are provided with pointed
spiked or porcupine surfaces nor do I confine or limit myself to the use of three of
such forked rollers though I prefer such number.
In some cases I employ cog wheels the pitch and foundation of the teeth being
such as to permit the cogs to partly gear though covered by an india rubber or other
elastic sheet covering secured around the teeth and which is by one tooth stretched
and forced in and between two teeth of the other wheel and by the use of same. I
secure for particular fibres the desired short draught, that is to say, as the fibre is
carried down between the teeth it is elongated as drawn out according to the depth
and foundation of the teeth on the wheels employed.
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 :-
1. In fibre drawing apparatus the use of studded and the guide rollers provided
with endless elastic bands or webs all in combination as herein described and
substantially as illustrated by annexed drawings.
2. The employment for purpose of drawing fibres, of cog wheels, the cogs of one
or both of which are covered with elastic material such as sheet india rubber for
purpose herein set forth and as illustrated by drawings annexed hereto.
