I JAMES BARBOUR of the firm of Combe Barbour & Combe Limited Falls
Foundry Belfast Ireland. Machinist. do hereby declare the nature of this inven-
tion to be as follows:-
-
This invention is carried out by the use of an additional delivery roller geared
into and revolving with the present delivery roller and supported by the carriage
plates in the usual way.
The centre of this roller being level or nearly so with the centre of the present
roller. The material to be operated on is pressed between these two rollers and
delivered in a perpendicular direction into the cans.
The rollers being level or nearly so with one another enables this to be done.
In the ordinary drawing frames the material in its passage from the sliver
plate to the delivery rollers passes through fixed conductors.
.
In my invention these conductors are replacell by flanges on one of the delivery
rollers which revolving with the roller serve to guide the material to the point
of pressure between the two rollers.
By these means the usual pressing rollers with their supporting horns are
entirely dispensed with:-thus simplifying the construction of the machine &
at the same time affording greater facilities for the attendant.

COMPLETE SPECIFICATION.
Improvements in Drawing Frames for Flax, Hemp, Jute, and similar
.
Fibres.
I, JAMES BARBOUR, of the firm of Combe, Barbour, & Combe, Limited, Falls
Foundry, Belfast, Ireland, Machinist do hereby declare the nature of this inven-
tion 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 drawing frames for flax, hemp, jute,
and other fibies, the object being by a novel arrangement and combination of
drawing rollers and guides or conductors therefor to ensure the Sliver under
operation being delivered in a vertical direction into the sliver cans, and affords
greater facility to the operative attending to the machine. The invention also
simplifies the construction of the drawing head by dispensing with the large

page_text: pressing rollers with their supporting horns and the fixed conductors for guiding
the sliver to the "nip" of the rollers. The invention consists of an additional
delivery roller gearing into and revolving with the ordinary delivery roller,
between which rollers the fibre is passed, and on one of the rollers are flanges
which serve as guides and obviate the necessity of the use of the fixed conductors
heretofore employed.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the annexed drawings, in
which:
Fig. 1 is a front elevation of as much of a drawing frame head as is required
to show the invention.
Fig. 2 is a plan viow of Fig. 1.
Fig. 3 is an end elevation of Fig. 1.
According to this invention, at 1 is the drawing roller of the drawing head,
2 being the delivery roller which occupies the same relative position to the
drawing roller 1 as hitherto. At 3 is an additional delivery roller carried level,
or nearly so, with the roller 2, and geared with it by means of wheels 4 and 5.
The roller 3 is pressed against the roller 2 by means of spiral springs G. The
position of the rollers 2 and 3 ensures the sliver 7 under operation being delivered
in a vertical manner, as indicated by the arrow, into the sliver can..
The delivery roller 2 is provided with adjustable flanges 8-S which are set
to suit the required width of sliver 7 and secured by set screw or like device.: these
flanges 8-8 revolving with the roller 2 to guide the sliver 7 to the point of
pressure and "nip" between the rollers 2 and 3, and dispense with the fixed con-
ductors heretofore necessary.
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) The arrangement and combination of parts comprising an additional delivery
roller 3, a delivery roller 2 having flanges 8-8, the rollers .2. 3 being carried on
about the same level, as and for the purpose herein described and substantially as
illustrated by the annexed drawings.
(2) A delivery roller 2 combined with an additional roller 3 such roller 2
having flanges 8-8 acting as fixed conductors and revolving with such additional
rollers 3, all in combination as and for the purpose herein described, and sub-
stantially as illustrated by the accompanying drawings.
Dated this 25th day of September 1897.
