Improvements in Machines for Drawing and Gill Spinning Binder
Twine, Rope, and other like Yarns.
We JAMES BARBOUR, ABRAM COMBE Machine Makers and JAMES FORD
Machinist, all of Falls Foundry Belfast Co. Antrim Ireland do hereby declare
the nature of this invention to be as follows:-
When the operation of drawing hemp flax, and other like fibres, by drawing
rollers is being performed, a difficulty arises through divergent fibres adhering to
and lapping round the sheet or gills instead of passing through the drawing rollers,
and this invention is designed to remedy the defect referred to and consists in the
application and use of a reciprocating lifting or raising and lowering instrument,
applied between two or more of the gill bars, so as to raise or lift all the fibres
from the bottom of the gill pins to near the top of said pins prior to their being
withdrawn from the fibres.
A suitable instrument for purpose aforesaid, consists of a rod or bar having a
reciprocating motion by lever tappet or cam so as to pass upwards between one or
more of the spaces between the gill bars nearest the drawing end, and so lift the
fibres upwards towards the points of the gills, thereby presenting the fibres more
directly to the drawing rollers and consequently resulting in forming a more
uniformn yarn.
Or instead of a reciprocating rod or bar a combination of reciprocating rod or
bar and an armed boss may be employed or a boss having teeth or radial strips
of india rubber or radial wires of hardened and tempered steel made in the form
of staples, may be fixed in such boss, so that the arms or teeth of the boss, or
the radial strips of india rubber, or the radial staple wires of hardened and
tempered wire, gear with the spaces between the bars of the gills, and thereby
operate on the fibre by lifting the same as and for purpose described.

COMPLETE SPECIFICATION.
Improvements in Machines for Drawing and Gill Spinning Binder
Twine, Rope, and other like Yarns.
We JAMES BARBOUR, ABRAM COMBE, Machine Makers and JAMES FORD,
Machinists all of Falls Foundry Belfast Co. Antrim, 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 :-
When the operation of drawing hemp, flax and other like fibres by drawing
rollers is being performed, a difficulty arises through divergent fibres adhering to
and lapping round the sheet or gills instead of passing through the drawing rollers,
and this invention is designed to remedy the defect referred to, and consists in the
application and use of a reciprocating lifting or raising and lowering instrument
applied between two or more of the gill bars so as to raise or lift all the fibres >
from the bottom of the gill pins to near the top of said pins prior to their being
withdrawn from the fibres.

page_text: A suitable instrument for purpose aforesaid consists of a rod or bar having a
reciprocating motion by lever tappet or cam so as to pass upwards between one or
more of the spaces between the gill bars, nearest the drawing end and so lift
the fibres upwards towards the points of the gills thereby presenting the fibres
directly to the drawing rollers and consequently resulting in forming uniform
varn.
Or instead of the reciprocating rod or bar just described a combination of
reciprocating rod or bar and a rotating armed boss may be employed or a boss
having teeth or radial strips or vanes of india rubber, or radial wires of hardened
and tempered steel made in the form of staples may be fixed in such boss
so that the arms or teeth of the boss, or the radial staple wires of hardened
and tempered wire gear with the succeeding spaces between the bars of the
gills, and thereby operate on the fibre by lifting the same as and for the purpose
described.
Such being the nature and object of this our said invention the following is a
complete description of same, reference being had to the accompanying drawings
in which
Fig. 1 is a sectional elevation of as much of a gill drawing frame as is necessary
to shew the nature of our invention.
Fig. 2 is a plan view of Fig. 1.
Fig. 3 is an elevation of the tappet or cam G.
Fig. 4 is a sectional elevation shewing a boss having projections gearing into the
spaces between the gill bars.
Fig. 5 is an enlarged view of Fig. 1.
The gill bars a which are connected to each other by the links a¹ are carried
round by the carrier wheels bb' which gear with the gill bars.
The rocking
levers c c² which carry the-bar or rod d are fixed to the rocking shaft e which is
carried on the framing.
This rocking shaft has another lever fattached to it, one end of which is
actuated by a cam or tappet g driven from any convenient going part of the frame
(preferably the carrier shaft g¹) this cam or tappet being shaped in such a manner
that the rod or bar d by the connection already described will have imparted to it
a rising and falling motion in the space between the gill bars, this operation being
performed in each of the spaces between the gill bars as the sheet advances.
the arrangement shewn the rod or bar d falls by its own weight and that of the
levers cc, but it is obvious that by making the cam g with a groove corresponding
to the contour of cam g the reciprocating motion of the rod or bar d would then
be positive in both directions.
In
In Fig. 3 a boss having longitudinal radial arms, projections or vanes is shewn.
These arms, projections or vanes may be made of strips or rubber or tempered
steel staples the said boss being keyed on to the carrier shaft, these strips of
rubber or steel staples being made of a length suitable to the width of gill on the
gill bars the radial arms, strips or projections gearing into the succeeding spaces
between the gill bars as the latter traverse over the said boss.
At 2 is the ordinary trumpet mouth into which the fibre is drawn from the pins
in the usual manner.
By the use of these our improvements the sliver or fibre under operation as it
is about to leave the gill bars is raised from the bottom of the gill pins to near
the top of said pins, thus all tendency for the divergent fibres to lap round the
sheet is prevented and such fibres pass forward with the bulk of the fibre under
operation whereby an even and much better sliver than has hitherto been obtainable
is ensured.
.
Having now particularly described and ascertained the nature of this our inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In gill drawing frames a reciprocating rod or bar in conjunction and

page_text: combination with the gill bars and working in such a manner that as the gill bars
advance the rod or bar rises and falls in each succeeding space between said gill
bars raising the fibre as and for the purpose aforesaid.
2. In gill drawing frames boss working in conjunction, and in combination
with the gill bars and having radial arms, projections or vanes gearing into each
succeeding space between the gill bars and lifting the fibres as and for the purpose
aforesaid.
