PROVISIONAL SPECIFICATION.
Improvements in Sliver Conductors of Gill Drawing Frames.
I, JAMES BARBOUR, of the Firm of Combe, Barbour, and Combe, Limited, of
Falls Foundry, Belfast, Ireland, Machinist, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in the form or shape of the sliver con-
ductors as applied to the rollers of gill drawing frames the object being to
obviate the defects arising from the use of the conductor " constructed "in tlie
ordinary manner and consequently acting on the outer edges only of the sliver
when contracting same and thereby tending to thicken each side of the sliver
leaving the centre thiu, thus producing a sliver of uneven thickness in its width.
The present invention obviates these defects by making the conductor so that
it acts on all the fibres composing the sliver when contracting its width and by
producing a sliver of equal thickness throughout the pressing rollers are not
subjected to the same amount of wear and tear and are more durable and a better
yarn is produced the sliver being contracted equally across its width.
According to this invention the conductor is made in the ordinary manner
and is fixed or held above and adjacent to the front or drawing roller as usual.
Each conductor has a hole in it, the side of which hole where the sliver bears being
made of two inclined faces with the inclinations of each towards the centre of the
aliver. The tension on the sliver as it passes over the inclined surfaces causes
it to consolidate to the required width, all the fibre of the sliver being acted on
with the result that a sliver of equal density or thickness throughout its width
is produced.
A like concave guide or conductor may be placed between the drawing and
the delivery rollers so that the slivers are further contracted and consolidated
before reaching the delivery rollers.

Improvements in Sliver Conductors of Gill Drawing Frames.
I, JAMES BARBOUR, of the Firm of Combe, Barbour, and Combe, Limited, of
Falls Foundry, Belfast, Ireland, Machinist, do hereby declare the nature of this
invention and in what manner the same is to the performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to improvements in the form or shape of the sliver

page_text: conductors as applied to the rollers of gill drawing frames the object being to
obviate the defects arising from the use of tlie conductor constructed in the
ordinary manner which act on the outer edges only of the sliver when contracting
same and thereby tending to thicken each side of the sliver leaving the centre
thin thus producing a sliver of uneven thickness in its width.
The present invention obviates these defects by making the conductor so that
it acts on all the fibres composing the sliver when contracting its width and by
producing a sliver of equal thickness throughout, the pressing rollers are not
subjected to the same amount of wear and tear and are more durable and a better
yarn is produced, the sliver being contracted equally across its width.
Such being the nature and object of my said invention the following is a com-
plete description of same, reference being had to the annexed drawings, in
which:-
Fig. 1 is a sectional side elevation of the improved sliver conductor the position
of the top drawing roller being indicated by the dotted lines.
Fig. 2 is a front elevation of the improved sliver conductor and drawing rollers
the upper one being indicated by the dotted lines.
According to this invention the conductor 1 is made in the ordinary manner
and is fixed or held above and adjacent to or rests upon the front or drawing
roller 2 as usual. Each conductor 1 has an opening 3 in it the side of which
opening where the sliver bears being made of two inclined faces 4 4 with the
inclinations of each towards the centre of the sliver (see Fig. 2). The tension
on the sliver as it passes over the inclined surfaces 44 causes it to consolidate
to the required width, all the fibre of the sliver being acted on with the result
that
a sliver of equal density or thickness throughout its width is produced.
A like concave guide or conductor may be placed between the drawing and the
delivery rollers so that the slivers are further contracted and consolidated before
reaching the delivery rollers.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is
Sliver conductors as herein described having an opening with two inclined faces
directed towards the centre of the sliver whereby the latter is consolidated, as and
for the purpose set forth.
Dated this 29th day of March 1900.
JAMES BARBOUR.
