PROVISIONAL SPECIFICATION.
Improvements in Automatic Stop Motions applicable to Slubbing
and other Drawing Boxes.
I, JOHN WILLIAM GAUNT, of Summerfield, Bramley, in the County of York,
Worsted Spinner, do hereby declare the nature of this invention to be as follows:-
This invention relates to certain improvements in automatic apparatus for
stopping machines used in the preparation of fibres for spinning into yarn, and has
for its object, the construction of the same in such a manner that, whenever a
thread or cord of fibre is broken, or the supply exhausted, the machine will be
stopped before the end of the broken or exhausted thread of fibre arrives at the
carrying rollers, and thereby to obtain a more uniform thickness in the thread when
two or more threads or cords are combined for reduction in thickness by the
operation of the machine through which the fibre is passing, and consequently to
prevent a corresponding amount of waste produced by the machine when the
threads are conducted to the same in the ordinary manner.
I accomplish my object in the following manner: Between the supply bobbins
and carrying rollers of the machine mount a series of detector wires, through
each of which a cord of fibre passes and suspends same above and clear of a
rotating cylinder having a number of radiating vanes secured to the circumference
thereof. This cylinder is driven through a pair of frictional clutches by preference
with gearing, and so long as the detectors are elevated by the tension of the cords
of fibre, the cylinder continues to rotate, but should a thread or cord of fibre be
broken or the supply exhausted, the detector wire drops on the circumference of
the cylinder, and on one of the radiating vanes coming in contact with the detector,
the rotation of the cylinder is stopped, then the sliding portion of the frictional
clutch is operated in a lateral direction on the shaft, by which through a series of
levers and rods, the belt guide is actuated in the direction for removing the belt
from the fast to the loose pulley, thus automatically stopping the machine until the
detector is again suspended by a continuous thread.

COMPLETE SPECIFICATION.
Improvements in Automatic Stop Motions applicable to Slubbing
and other Drawing Boxes.
I, JOHN WILLIAM GAUNT of Summerfield, Bramley, in the County of York,
Worsted Spinner, 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 automatic apparatus for
stopping machines used in the preparation of fibres for spinning into yarn, and has
for its object the construction of the same in such a manner that, whenever a thread
or cord of fibre is broken, or the supply exhausted, the machine will be stopped
before the end of the broken or exhausted thread arrives at the delivery rollers and
thus to obtain a more uniform thickness in the thread or yarn produced when two
or more threads or cords of fibres are combined for reduction in thickness by the
operation of the machine through which the fibre is passing and thereby to reduce
the amount of waste produced by the machine when the threads or cords are con-
ducted to the rollers in the ordinary manner.

Fig. 1. represents an end view of certain portions of a slubbing or drawing frame
to which my improvements are added.
Fig. 2. is a front view of a portion of the frame, certain parts being broken away.
Fig. 3. a sectional detail through the stop cylinder and detector rail.
Fig. 4. details of the operating clutch plates.
Fig. 5. a back elevation of a portion of the frame, and
Fig. 6. a detached plan of my improvement.
The machine partly illustrated by Figs. 1. 2. and 5. is constructed and driven in
the ordinary manner and my improvement may be placed in any convenient position
between the supply bobbins A. mounted on pins at the back part of the machine
and the ordinary carriers and rollers B. with suitable connections to the belt
.guide bar.
To the additional longitudinal bar C. extending the length of the machine are
attached a number of bosses D. through which pass a series of detector wires E.
each being suspended by a cord or thread of fibre F. passing through an ordinary
guide W and an eye or opening formed at the top of each detector. The tension
of the respective cords of fibre keep the detector wires E. above and clear of a
rotating cylinder G. prepared with a number of radiating vanes G₁ secured to the
circumference thereof, and which may be driven preferably at a slow rate of speed
by a pitch chain or belt connection or by gearing H. connected with some rotating
shaft of the machine in the following manner.
The spur wheel H' or if a pitch chain wheel or pulley be used in lieu thereof,
the same is free on the cylinder shaft, and to the said spur wheel or its equivalent,
is secured a clutch plate J. having two or more angular projections J' on the face
thereof. Another clutch plate K. is mounted on the cylinder shaft in such a
manner that, it will not rotate thereon, but is free to slide on same and is kept in
contact with the clutch plate J. by a spiral spring S. on the cylinder shaft com-
pressed against the boss of clutch plate K. by nuts N. the cylinder G. being driven
by the spur wheel H' or its equivalent through the clutch plates J. and K.
So long as the detectors E. are elevated by the tension of the cords of fibre F.
the cylinder G. continues to revolve, but should a cord of fibre F. be broken, or
the supply on a bobbin A. exhausted, the detector wire E. will drop and rest upon the
circumference of the cylinder G. so that, on one of the radiating vanes G¹coming
in contact with the detector, the rotation of the cylinder G. and clutch plate K.
are stopped, but the spur wheel H or its equivalent and clutch plate J. continue
to revolve, and by the angular projections on rotating clutch plate J. pressing
against the angular projections K on clutch plate K. the latter is caused to slide
on the cylinder shaft in the direction of the arrow.
A lever L. is mounted on a fulcrum pin carried by bracket M. one arm of the
lever being in contact with the plate of the clutch K. and on the other arm of the
lever is fixed an adjustable block N' having an inclined plane on one side, for
the purpose as hereinafter described.
Mounted in suitable journals is a shaft P. on which is secured a disc Q. provided
with a tongue R. projecting therefrom, which when the machine is in motion, rests
upon and is supported by the inclined plane on block N¹. The disc Q. is provided
with an arm Supon which is secured a weight T. and on the shaft P. is attached
a lever U. having a slot hole near to one end with which engages a pin projecting
from the sliding belt fork bar V.
When a detector wire is allowed to drop on to the circumference of the cylinder G.
the clutch plate K. is forced back in the direction of the arrow in the manner as
hereinbefore described, by which the lever L. is operated on its fulcrum pin and
moved into a position somewhat as shown by dotted lines in Fig. 5. a distance
sufficient to remove the inclined plane of block N' clear of the tongue R. thus
removing the support and thereby allowing the weight T. to descend and operate
the lever U. and belt fork bar V. into the position shown by dotted lines, thus
moving the belt from the fast to the loose pulley; by which the machine is stopped

page_text: automatically whenever a detector wire E. is allowed to come in contact with the
cylinder G.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination of the parts forming the complete apparatus for automatically
stopping the machine whenever a cord of fibre breaks or the supply is exhausted
all arranged substantially in the manner as hereinbefore described and illustrated
by the accompanying drawings.
2. The combination of the detector wires E. with the cylinder G. spur wheel H¹
or equivalent chain wheel or pulley catch plates J. and K. spiral spring S. nut N.
and lever L. arranged substantially in the manner and for the purpose as herein-
before set forth.
3. The combination of the lever L. block N¹ disc Q. and tongue R. with the
shaft P. lever U. and belt fork bar V. arranged substantially in the manner and
for the purpose as hereinbefore set forth.
