We, HENRY ILLINGWORTH of the firm of Daniel Illingworth and Sons, Whetley
Mills, Bradford, in the County of York, Spinner, and JAMES TARBOTTON of the
same place, Foreman, do hereby declare the nature of our invention for IMPROVE-
MENTS IN APPARATUS FOR AUTOMATICALLY STOPPING GILL, SLUBBING AND OTHER
DRAWING BOXES to be as follows
This invention relates to certain improvements in gill, slubbing and other
drawing boxes, through which slivers or cords of fibre are passed for the purpose of
reducing the same preparatory to spinning, and has for its object the arrangement
of the boxes in such a manner, that when one of the slivers or cords of fibre
breaks, the machine will stop automatically and thus prevent not only waste, but
any deviation in the thickness of the reduced slivers or cords of fibre passing
through the machine, which we accomplish in the following manner :-
In addition to passing the slivers or cords of fibre through the ordinary guides
placed between the creel and back rollers, we pass each sliver or cord through a
ring, each of which is supported by its respective sliver and in contact with an
additional guide, which is placed at a sufficient distance from the back rollers to
allow sufficient room between the two guides for piecing the sliver or cord when
necessary. In case any sliver or cord of fibre is broken or the supply exhausted,
the ring being no longer supported, drops, and is guided on to a plate or tray
hinged on a bar that extends the full length of the machine; by which ring, the
hinged plate or tray is displaced and moved into such a position that it comes in
contact with a projection on a reciprocating bar immediately under the same, thus
forming a connection between the two bars; by which means a series of levers in
connection with the bar upon which the hinged plates are mounted, are operated
upon, thus causing. the driving belt to be moved from the fast to the loose pulley
thereby stopping the machine.

We, HENRY ILLINGWORTH of the firm of Daniel Illingworth and Sons, Whetley
Mills, Bradford, in the County of York, Spinner, and JAMES TARBOTTON of the
same place, Foreman, 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 certain improvements in gill, slubbing, and other
drawing boxes, through which slivers or cords of fibre are passed for the purpose
of reducing the same preparatory to spinning; and has for its object, the arrange-
ment of the boxes in such a manner, that when one of the slivers or cords of fibre
breaks, or the supply exhausted; the machine will stop automatically, and thus
. prevents not only waste, but any deviation in the thickness of the reduced slivers
or cords of fibre passing through the machine.
The invention consists in passing the slivers or cords through guides and rings,
the latter being supported by its respective cord or sliver. When any cord or
sliver of fibre is broken, or the supply exhausted, the ring drops on to a hinged
plate or tray, causing it to come into contact with a projection on a reciprocating
bar, and thereby actuate another bar by which levers in connection with the belt
guide are operated, thus causing the driving belt to be moved from the fast to the
loose pulley, thereby stopping the machine.
In the accompanying drawings, Fig. 1 represents the end elevation partly in
section of an ordinary drawing box with our apparatus added thereto, such portions
of the machine not required to elucidate our invention being omitted.. Fig. 2 is a
back view. Fig. 3 a detailed sectional end view of the back guide, bars, and tray;
Fig. 4 a view of a ring, and Fig. 5 a section thereof.
We place two guides between the bobbin creel A and the back rollers B,, and
pass each sliver or cord C through a ring R, each of which is supported by its
respective sliver or cord, and is in contact with the back guide D, placed at a
distance from the back rollers B, to allow sufficient space between the back and
front guides D and E for piecing the sliver or cord when necessary.
In case any
sliver or cord of fibre is broken, or the supply exhausted, the ring R being no
longer supported, drops, and is guided on to its plate or tray F hinged to the bar G
supported by suitable brackets.
By the force of the falling ring, the hinged plate or tray F is moved on the
hinges into the position shewn at H against the reciprocating bar J, which is
actuated by the cord C₁ and revolving pullies L and M; the pulley M having a
stud in the side thereof, to which is attached the reciprocating bar J by the
connecting rod R'.
A series of projections P corresponding with the number of trays, are formed on
or attached to the bar J, and when one of the plates or trays F is displaced in the
manner as before described, the respective projection P on the reciprocating bar
"

page_text: coming in contact with the same, forms a connection between the bars J and G,
thereby moving the top bar G in the direction of the arrow.
To the bar is secured projection S, which is connected or in contact with the
train of levers T, and when the bar.G is moved in the direction of the arrow as
before described, the levers T and belt guide W are actuated, the latter moving the
belt from the fast to the loose pulley, thereby stopping the machine whenever the
fibre or cord is broken or the supply exhausted.
Having now particularly described and ascertained. the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is
The bars J, and G, with trays F used in combination with the rings R for
stopping the machine automatically when any sliver or cord of fibre breaks or
the supply exhausted, all arranged substantially in the manner shewn and
described.
