Complete Specification Left, 28th Apr., 1900-Accepted, 2nd June, 1900
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 gill drawing frames and to the
uniting or doubling of the separate slivers delivered from the drawing rollers
to the delivering roller.
The uniting or doubling of the slivers has hitherto been carried out by the
use of sliver plates with angled slots through or along which the several slivers
travelled in their passage from the drawing roller to the delivery roller and
were thereby diverted from their straight course and united or doubled as
required at the delivery roller.
In practice it has been found by this arrangement that each of the slivers
was subjected to more or less friction according to the smoothness of the dead
surfaces over which it passes consequently the different slivers were subjected
to different tensional strains and the effect was to elongate some of the slivers
more than others thereby causing an unequal reunion of the slivers at the
delivery roller.
The object of the present invention is to obviate this defect and this is
achieved by dispensing with the dead or non-moving surfaces for changing the
direction of and conveying the slivers and substituting therefor revolving or
travelling surfaces travelling at the same or practically the same surface speed
as the sliver, and by this means the separate slivers in their passage towards
the delivering roller are subjected to a uniform and minimum amount of friction,
consequently a more uniform sliver is obtained.

Improvements in 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 be performed, to be particularly
described and ascertained in and by the following statement:-
-
This invention relates to improvements in gill drawing frames and to the
uniting or doubling of the separate slivers delivered from the drawing rollers
to the delivering roller.

page_text: The uniting or doubling of the slivers has hitherto been carried out by the
use of sliver plates with angled slots through or along which the several slivers
travelled in their passage from the drawing roller to the delivery roller and
were thereby diverted from their straight course and united or doubled as
required at the delivery roller.
in practice it has been found by this arrangement that each of the slivers
was subjected to more or less friction according to the smoothness of the dead
surfaces over which it passes, consequently the different slivers were subjected
to different tensional strains and the effect was to elongate some of the slivers
more than others, thereby causing an unequal reunion of the slivers at the
delivery roller.
The object of the present invention is to obviate this defect and this is
achieved by dispensing with the dead or non-moving surfaces for changing the
direction of and conveying the slivers, and substituting therefor revolving or
travelling surfaces travelling at the same or practically the same surface speed
as the slivers, and by this means the separate slivers in their passage towards
the delivery roller are subjected to a uniform and minimum amount of friction;
consequently a more uniform sliver is obtained.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the accompanying drawings,
in which:-
Fig. 1 is a sectional side elevation of the improvements in gill drawing
frames.
Fig. 2 is a plan view of Fig. 1.
According to this invention at 1, 1 are the delivery rollers and at 2,2 the
drawing rollers, the slivers 3,3 being shewn as passing from one to the other
and being diverted from a straight line between the said delivery and drawing
rollers. The slivers are diverted by passing partly around the two guides 4,4
which consist of small cylindrical blocks or pulleys loosely carried and free to
revolve on the spindles or pins 5,5, and such guides 4,4 constitute revolving
or travelling surfaces, being caused to revolve on their pins or spindles 5,5 by
the frictional contact of the slivers 3, 3, consequently the surfaces or guides 4,4
travel at the same speed as does the slivers and there is little or no tensional
strain on the latter.
The guides 4,4 may be of the form shewn or in the form of small pullies or
wharles so long as the surface or guide is so mounted as to revolve or travel
with the frictional contact of the sliver.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
The use in combination with the drawing and delivery rollers of a gill
drawing machine of revolving guides such as 4, 4 as and for the purpose herein
described.
