JAMES BARBOUR of Falls Foundry Belfast County Antrim Ireland do hereby declare
the nature of this invention to be as follows :-
This invention relates to conductors employed. in connection with the drawing
rollers of screw and chain gill. machinery for preparing flax hemp tow and other like
fibres, and consists of an improved construction on such appliances for which letters
putent No. 2519, A.D. 1879 were granted to the present applicant.
The present invention having for its object to prevent the divergent fibros entering
and accumulating between the inner or bearing surface of the "jaws" and the
bottom drawing roller, a defect of my previous appliance when strong fibres and
such as were not thoroughly cleaned were under operation was the accumulation
referred to.
According to this my present invention I so construct the conductor that its jaws
are on each side of the pressing rollers. The front bearing or supporting portions of
the jaws which in my previous appliance were in contact with the guiding rollers and
which bearing so made was apt to trap and entangle any loose or divergent fibres
which accumulated under the bearing and raised or lifted the conductor out of its
working position.
To remedy such defect I now mount upon or spring from side or carrying pieces
at about right angles to the draft or traverse of the fibre the front bearings of the jaws
so that any loose or divergent fibre cannot be entangled with such bearings but must
pass with the main body of fibre from the nip of the rollers.
The construction of appliances as aforesaid wherein is combined the guiding
jaw side pieces and supporting parts of the jaws entirely rids the conductor of the
imperfections and defect referred to.
Dated this 8th day of February 1888.

Improvements in Sliver Conductors for Drawing Rollers.
I, JAMES BARBOUR of Falls Foundry, Belfast, County Antrim Ireland, 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 conductors employed in connection with the drawing
rollers of screw and chain gill machinery, for preparing flax, hemp, tow and other like
fibres and consists of an improved construction on such appliances for which Letters
Patent No. 2519 A.D. 1879 were granted to the present applicant.
The present invention having for its object to prevent the divergent fibros,
entering and accumulating between the inner or bearing surface of the jaws and tho
bottom drawing roller, a defect of my previous appliance, (when strong fibres and
such as were not thoroughly cleaned were under operation) was, the accumulation
referred to.
According to this my present invention I so construct the conductor, that its jaws
are on each side of the pressing rollers. The front bearing or supporting portions
of the jaws are out of contact with the pressing or guiding roller but which in my.
previous appliance were in contact with the guiding rollers and which bearing so made
as heretofore was apt to trap, and entangle any loose or divergent fibres, which
accumulated under the bearings, and such accumulations raised or lifted the conductor
out of its working position.
Such being the naturo and object of my said invention, the following is a complete
description of same reference being had to the accompanying drawings, forming part
of this specification in which :-
Fig. 1 is a sectional end elevation of the drawing rollers, gills, and improved
conductor, the latter in elevation.
Fig. 2 is a plan view of conductor, top roller omitted.
Fig. 3 is a front elevation of the conductor detachod.
Fig. 4 is an oblique or isometrical view of the conductor.
At 1 is the top roller, 2 the bottom roller, 3 the gills, 4 the fibre, at 5 is the conductor
its upper end 6 being worked over a supporting bar 6. Springing from the side
pieces 7-7 are the bearing pieces 8-8 these are distended leaving the whole space
between the sides of the conductor at a-b, clear for passage of fibres, the parts 8-8
being outside and beyond the passage way of the fibres, there is no catching
and accumulation of such, nor displacement of the conductors as heretofore.
I have now described my improved conductor, wherewith 1 can effectually prevent
the accumulation of fibre thereunder, and prevent displacement thereof, but I would
remark it is obvious that the form of the bent portion 8, may be varied, without
departing from the principle of the invention, so long as it is provided that the
supports 8-8 are without and beyond the outer edges or margins of the fibres, passing
through the conductor.

page_text: Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed I declare that what
I claim is: -
Conductors for purposes set forth wherein the front supporting parts thereof, are
without or beyond the inner line of the guiding jaws for purposes herein described,
and substantially as illustrated by drawings annexed.
