Improvements in and relating to Feeding the Slivers to Gill Boxes.
We, ROBERT HEWILSON, of 22, Sherry Road, Tong Street, Dudley Hill, in the
City of Bradford, Manager, and EDWARD JAMES SMITH, of Anchor Works,
Dudley Hill, Bradford aforesaid, Wool Comber, do hereby declare the nature
of this invention to be as follows:---
This invention has for its object the feeding of the slivers to gill boxes at a
uniform tension in such a manner that, the combined slivers after passing through
the gill box are of a more uniform thickness, the fibres being straighter, laying
more parallel to each other, and not so wavey or curly or uneven in thickness as
is the case when the barrels containing the feeding slivers are mounted in the
manner as hitherto.
In carrying out our invention, the slivers are wound upon barrels into what
are termed balls" as hitherto, and the barrels containing the balls" are
placed upon creel spindles, upon each of which is a boss free to rotate on the
spindle.
Each boss is provided with one or more projections which engage with one end
of a barrel in such a manner that, on the barrel rotating on the creel spindle,
the boss rotates also.
Around and in contact with each boss, we place a strap of suitable material,
the strap being carried by a stud and so arranged as to bind on the circumference
of the boss, and thereby act as a brake, the amount of friction between the strap
and boss being regulated by a screw which determines the speed at which the
fibre under operation is fed from the barrel on the creel to the rollers of the box.
By mounting the before mentioned barrels in the manner described, the
désired tension on each sliver, as it is fed to the fallers of the gill box, is obtained
by the adjustment of the friction between the respective clips and bosses, so
that no ball of fibre can rotate except at the required speed at which the sliver
is drawn by the rollers from the feeding ball, thereby keeping the fibres as they
are drawn from the balls and fed to the machine in a stretched condition, which
ensures the pins of the fallers passing through the fibre and thus straightening
same. So long as the tension on the slivers is maintained, the fibre is retained
below the points of the faller pins, and cannot rise above the pins as is now
sometimes the case when the slivers are mounted and fed to the machine in the
manner as has hitherto been the common practice.

page_text: Dudley Hill, Bradford aforesaid, Wool Comber, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
This invention has for its object, the feeding of slivers to gill boxes at a
uniform tension in such a manner that, the combined slivers after passing
through the gill box, are of a more uniform thickness, the fibres being straighter,
laying more parallel to each other, and not so wavy, curly or uneven in thick-
ness, as is the case when the barrels containing the feeding slivers are mounted
in the manner as hitherto.
As is well known to persons skilled in the preparation of fibres for spinning,
that when slivers are fed to gill boxes at unequal or varying tensions, the reduced
resulting slivers are uneven in thickness and there the slivers are thicker, the
fibres do not lay so straight and parallel to each other, as where the sliver is of
the required thickness.
In describing our invention in detail, reference is made to the accompanying
sheet of drawings, in which Fig. 1 represents a portion of an ordinary creel
stand, showing a spindle with barrel thereon, combined with our retarding
mechanism.
Fig. 2 is an end view drawn to an enlarged scale.
Fig. 3 is a plan view showing a means of supporting the brake strap, and
Fig. 4 a section through the boss or collar of our retarding mechanism.
In carrying out our invention, the slivers of fibre are wound upon barrels A
into what are termed balls as hitherto, and the barrels containing the balls,
placed upon creel spindles B, upon which we place a boss C free to rotate.
Each boss C is provided with one or more projecting pins D, which, when a
barrel A is placed upon a spindle B, engage with perforations formed in the
end of the barrel, so that on the barrel revolving on the creel spindle B, the
boss Crevolves also.
Around and in contact with each boss C, is placed a light metal strap E, con-
nected to a plate F, which may be secured to à creel standard G of the ordinary
description, or suitably secured to spindle B, such as forming a portion of the
spindle square, placing the arm F of plate thereon, and nipping same between
the spindle collar B and creel standard. The strap E is by preference lined
with a cushion of leather or like suitable flexible material E, and is provided
with projecting lugs 2 through which is passed a threaded bolt H provided
with a nut, by the regulation of which, pressure is put upon or removed from
the circumference of the boss C, thus regulating the amount of friction between
the boss and strap E.
By mounting barrels A on creel spindles B, and combining same with bosses C
in the manner described, the desired tension on each sliver is obtained as it is
fed to the ordinary rollers and fallers of a gill box, by the adjustment of amount
of friction between the respective straps E and bosses C, so that no barrel A
and ball of fibre thereon, can rotate except at the speed at which the sliver is.
drawn by the feed rollers, mounted and operated in the usual manner, thereby
keeping the slivers as they are drawn from the balls in a stretched condition
giving an uniform feed, and ensuring the pins of the fallers of the gill box,
arranged and operated in the usual manner, to pass through the fibre and thus
straighten same.
.
So long as the tension on the slivers between the balls of fibre on barrels A,
and the gill box feed rollers is maintained, the slivers are fed regularly, and
by the regularity of feed, the fibre is retained below the points of the faller pins;
the retarding in the rotation of the barrels A with balls of fibre thereon pre-
vents the balls over running, and the fibre coming in contact with the floor,
collecting foreign matter therefrom, or ruffling the fibres, that is to say,
disturbing some of them that they do not lay parallel to each other; also pre-
vents the rollers of the gill boxes collecting additional feed which in some cases,
when the fibre is slack, collect so much that, the faller pins cannot penetrate

page_text: through the whole of the fibre, so that some of the fibre rides on the top of the
faller pins, thus producing an unequal sliver.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is:-
A creel consisting of spindles Beach provided with a collar C and clip E
combined with a barrel A substantially in the manner and for the purpose as
herein before set forth and shown.
