We, ALBERT HOLDEN ILLINGWORTH, Spinner, and JAMES TARBOTTON, Foreman,
both of Whetley Mills, Bradford, in the County of York, do hereby declare the
nature of our invention for IMPROVEMENTS IN APPARATUS FOR PREVENTING
WASTE AND INSURING A UNIFORM THICKNESS OF SLUBBING OR CORD IN THE
DRAWING OR PREPARATION OF WOOL FOR SPINNING to be as follows:-
This invention relates to certain improvements in drawing, finishing, roving,
and analogous machines, through which slubbings or cords of fibre are passed for
the purpose of folding and reducing the same preparatory to being spun; and has
for its object the application to the machines of such an arrangement in such a
manner, that when two or more ends or cords are being fed to the back rollers,
should one end or cord of fibre break, the machine will stop automatically, and
thus prevent waste and any deviation in the thickness of the cord of fiore or what
is commonly called the slubbing or "roving."
This we accomplish by mounting between the creel or bobbin plate and the
back rollers, a bar passing from end to end of the machine through which pass a
number of twizzles or other guides, each of which is supported by a thread or cord
of fibre passing through the eye thereof: whenever any one cord of fibre is broken
or the bobbin forming the supply is empty, the twizzle drops because it is no
longer supported by the passing thread, the end of the twizzle falls into a hole in
a reciprocating plate immediately under the same, and of similar length as the
first mentioned bar, thus a connection is formed between the upper bar and the
lower reciprocating bar, by which means through the intervention of a series of
levers, the driving belt is moved from the fast to the loose pulley.
Or our invention may be carried into effect by using a circular bar in place of
the flat one, and mounting thereon twizzles each arranged with an arın on the
underside, so that whenever an end or cord of fibre is broken or run off the supply
bobbin, the arm will come in contact with the reciprocating plate, which according
to this arrangement is cut at the edge with a number of indentations corresponding
with the number of twizzles; thus, when an arm is engaged with an indentation,
the bar is moved end ways and throws the belt from the fast to the loose pulley,
thereby stopping the machine, preventing waste, and variations in the thickness of
the cord of fibre.

We ALBERT HOLDEN ILLINGWORTH, Spinner, and JAMES TARBOTTON, Foreman,
both of Whetley Mills, Bradford in the county of York do hereby declare the
nature of our invention for "IMPROVEMENTS IN APPARATUS FOR PREVENTING
WASTE AND INSURING A UNIFORM THICKNESS OF SLUBBING OR CORD. IN THE
'DRAWING OR PREPARATION OF WOOL FOR SPINNING," 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 drawing, finishing, roving, and
analogous machines, through which slubbings or cords of fibre are passed for the
purpose of folding and reducing the same preparatory to being spun; and has for
its object the application to the machines of such an arrangement in such a
manner that when two or more ends or cords of fibre are being fed to the back
rollers, should one end or cord of fibro break the machine will stop automatically;
and thus prevent waste and any deviation in the thickness of the cord of fibre, or
what is commonly called the slubbing or "roving."
We will describe our invention by aid of the accompanying drawings, in which
Fig. 1 represents an end elevation of an ordinary drawing or roving frame with
our improvement added thereto. Fig. 2, is a front view of a portion of the same
with some of the rollers removed in order to more clearly show our invention.
Fig. 3, is a detailed end view, and Fig. 4 a detailed plan of one of our methods.
Our invention consists in mounting between the ordinary creel or bobbin plate
and the back rollers R, a bar B, extending from end to end of the machine;
through which pass a number of twizzles or other guides C, each of which is
supported by a thread or cord of fibre Y, passing through the eye thereof.
Whenever any one cord of fibre Y is broken, or the bobbin D, forming the supply
is empty, the twizzle drops, because it is no longer supported by the passing
thread; the end of the twizzle falling into a hole in a reciprocating bar E
immediately under the same, and of similar length as the bar B; thus a connection
is formed between the upper bar B, and lower reciprocating bar E, by which
means through the intervention of a series of lovers, the driving belt is moved from
the fast to the loose pulley in the ruanner as hereinafter described.
Motion is communicated to the bottom back rollers R in the usual manner, and
to the shaft of the same is secured a cain F, in the groove of which engages a
bar G, that is attached to the adjustable projecting piece H of bar E, thereby
giving to the said bar a reciprocating motion.
To the upper bar B is also secured a projecting piece H', and when any of the
twizzles or guides C fall, the bottom ends engage with the corresponding hole N,
bored through the reciprocating bar E, thereby connecting the two bars which are
moved by the cam F, and the projecting piece H being in contact with the lever
arm J, the latter is moved also; which actuates the levers K, and belt fork K¹, and
moves the driving belt from the fast to the loose pulley.

page_text: Our invention may be carried into effect by using a circular bar B₁ in place of
the flat one B, and is shown in end elevation by detail Fig. 5, and in plan by Fig. 6.
According to this arrangement, the bottom bar E' reciprocates and is actuated in
the same manner as the bar E, but instead of having holes N, bored through, we
cut the edge of the bar with a number of indentations E corresponding with the
number of twizzles O¹, which we mount on a circular bar B¹. Each twizzle is
arranged with an arm C on the underside, so that whenever an end or cord of
fibre Y is broken, or the supply run off the bobbin, the twizzle is liberated; when
the arin C will come in contact with the reciprocating bar E¹ and engage with an
indentation E cut therein, thereby connecting the two bars B¹ and E which are
actuated by the cam F, and the driving belt moved from the fast to the loose
pulley by the levers and belt fork arranged in the manner as before described.
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 combination of the parts for automatically stopping the machine when any
of the cords of fibre break or the supply bobbin is empty, all arranged substantially
in the manner as shewn and described.
The use of reciprocating bars E and E' in combination with twizzles or guides
C and C for the purpose herein described and set forth.
