PROVISIONAL SPECIFICATION.
Improvements in Gill Drawing Frames.
1, JAMES BARBOUR of Falls Foundry, Belfast, Ireland, Machine Maker, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the method of and means employed
for actuating and guiding the gill bars in push bar drawing frames such as are
described in Specification of Letters Patent, dated 1st February 1884 granted to
the present applicant and Abram Combe and James Gamble and numbered 2545
and the invention consists of improvements whereby the gill bars are caused to
move through an irregular curve on their downward passage, after having carried
the sliver to the drawing roller instead of moving in a circular path as at present,
and also in dispensing with one set of carriers and employing only one set of carriers
to actuate the gill bars, whereby we ensure a better retaining of the material under
operation by the gill bars as they approach the drawing roller thus making the
drawing action more effectual and simplifying the construction of the machine by
dispensing entirely with one set of carriers.
According to this invention I employ back carriers only for actuating or pushing
forward the gill bars, the latter being carried on or passing over an irregular curved
cam or bracket the acute portion or angle of which is at the point where the fallers
descend from and leave the sliver, so that by this means the fallers or bars retain
their horizontal approach to the drawing roller longer and consequently retain and
operate on the material more effectually than heretofore.

Improvements in Gill Drawing Frames.
I JAMES BARBOUR of Falls Foundry, Belfast, Ireland, Machine Maker 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 the method of and means employed for
actuating and guiding the gill bars in push bar drawing frames such as are described
in Specification of Letters Patent dated 1st February 1884 granted to the present
applicant and Abram Combe and James Gamble and numbered 2545 and to further
improvements in connection with apparatus such as described in Specification of
Letters Patent dated 10th day of June 1893, granted to the present applicant and
numbered 11396 and the present invention consists of improvements whereby the
gill bars are caused to move through an irregular curve on their downward passage
after having carried the sliver to the drawing roller instead of moving in a circular
path as at present, and also in dispensing with one set of carriers, and employing
only one set of carriers to actuate the gill bars, whereby I ensure a better retaining

thus making the drawing action more effectual and simplifying the construction of
the machine by dispensing entirely with one set of carriers.
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
in which
Fig. 1. is a sectional side elevation of so much of a gill drawing frame as is
requisite to illustrate the invention.
Fig. 2. is an end elevation of the gill bars and pins, carrier bracket, and cam or
guiding path.
According to this invention I employ carriers 1 only for actuating or pushing
forward the gill bars 2, the ends of the latter being carried in or passing along an
irregular curved cam groove 3 formed in the bracket 4 the acute portion or angle
of which is at the point where the fallers 2 descend from and leave the sliver, so
that by this means the fallers or bars and pins 2 retain their horizontal approach
to the drawing roller 6 longer and consequently retain and operate on the material
more effectually than heretofore.
.
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 gill drawing frames the bracket 4 having an irregular curved cam groove 3
and the gill bars or fallers 2, actuated by carriers 1 all in combination as and for
the purpose herein described and substantially as illustrated by the accompanying
drawings.
(2.) In gill drawing frames the method of and means employed for actuating the
gill bars or fallers 2 by means of carriers 1 only the said gill bars or fallers being
pushed by the carriers along a cam groove 3 as and for the purpose herein described
and substantially as illustrated by the annexed drawings.
