PROVISIONAL SPECIFICATION.
An Improved Stop Motion for Application to Scutchers.
I RICHARD ASHWORTH of 109 Bridge Street, Farnworth, in the County of
Lancaster, Mill Manager, do hereby declare the nature of this invention to be
as follows:-
My said invention relates to scutching machinery for the treatment of cotton laps
as is well understood. In such scutchers the laps of cotton are supported by
revolving or traversing surfaces such as rollers or travelling lattices and one or
more of such laps is or are treated or mixed and scutched simultaneously by the
apparatus. I will for the sake of example but without prejudice or limitation,
describe my invention as applied to a scutching apparatus in which the laps rest
upon a travelling lattice, three such laps being a convenient and usual number. As
well known the laps after being formed, have usually the core upon which they are
wound removed and replaced by a smaller rod, the projecting ends of which extend
through bearing slots in the side frames. By the travelling of the lattice the
laps are unrolled and fed to the scutcher.
It will be apparent that if one of the lap rolls should become exhausted, the
quantity of cotton fed to the scutcher is diminished and the quality of the work
impaired, the thinning of the work caused by this exhaustion of one of the laps
being technically known as "single." The object of my invention is to prevent
this, and I have therefore devised an improved stop motion which is or may be
constructed and arranged as follows. In the first place I may point out that as the
lap roll diminishes in circumference the centre or core rod is lowered in the bearing
slots.
I form an extension on one end of each rod and at the foot of the slot I pivot a
bellcrank lever, the upper horizontal arm of which lies directly in the path of the
centre rod as it descends. Along the side of the frame and just below the slot.
bearings there is, in certain ordinary types of scutcher, a side shaft to connect and
drive the shafts and carrying discs at each end of the lattice. Upon this revolving
side shaft I fix a bevel wheel, which gears with another bevel wheel running
loosely on the end of a swing bracket hung or centred loosely on the shaft behind
the fixed bevel wheel. A third bevel wheel mounted loosely on the side shaft gears
with the second bevel wheel so that under normal circumstances all three wheels
revolve freely. On the back of the third bevel wheel, which as I have said is
loosely mounted on the shaft, I place one or more projections, and on the bell crank
lever I place a finger opposite to these projections and in such a position that if the
bell crank lever should be moved the finger will come against one of these
projections and stop the revolution of the loose bevel wheel. As the second bevel
wheel on its suspending bracket would still be revolved by the fixed bevel wheel on
the side shaft, it follows that the stoppage of the third bevel wheel in the manner
described would cause the second bevel wheel with its loosely pivotted bracket to
be carried round the side shaft. Formed on or attached to the pivot boss of the
said suspending bracket there is a pulley having wound upon it a cord with an
attached weight. The carrying round of the bracket and bevel wheel also effects
the rotation of the pulley so as to wind on the cord and raise the weight. On the
back of the pulley there is a projection which lies in the path of a projection
extending from one side of a washer mounted loosely on the side shaft, the other
side of the washer also carrying a projection lying in the path of a tooth extending

first. The first pulley in rotating with the pivotted bracket strikes a projection on
the washer and the washer as it is carried round strikes the tooth on the second
pulley or boss which is in its turn rotated. From this last pulley or boss I actuate
the stop lever, and this might be effected in any suitable manner; for instance a
cord might be wound on the second pulley or boss and connected to the stop lever
or a lever might extend from the boss and operate the strap fork or other means
used to arrest the motion of the machine. A. gong or bell might be connected to
any of the parts to give warning to the attendant of the stoppage of the machine.
The reason of the break between the first and second parts of the stop motion as
described is to give a dwell between the moment when the lap rod touches the bell
crank lever and the actual stoppage of the mechanism this being arranged to
provide for the excentric position of the lap rod in the central larger hole in the
lap roll.
Where there are several lap rolls it is only necessary to provide one such
mechanism as described for one lap roll the other laps having their bell crank levers
connected thereto by a side rod connected to the tails of all of the bell crank
levers.
When the empty lap rod is removed the loose bevel is released and the weight
on the first pulley falls, replacing the parts in their normal position ready for being
again actuated.
Where the aforesaid side shaft does not exist a short auxiliary side shaft can be.
applied to the side frame and driven from any suitable source.
do not limit myself to the exact construction and distribution of parts set-
forth as these might be modified without departing from the spirit of my
invention. In some cases I might employ electricity to communicate from
one lap roll to another or to operate certain of the parts of the mechanism
described.

An Improved Stop Motion for Application to Scutchers.
RICHARD ASHWORTH 109 Bridge Street Farnworth, Bolton Mill Manager,
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 :-
My said invention relates to the scutching machinery for the treatment of cotton
laps as is well understood. In such scutchers the laps of cotton are supported by
revolving or travelling surfaces such as rollers or travelling lattices, and one or
more of such is or are treated or mixed and scutched simultaneously by the
apparatus.
As is
"I will for the sake of example but without prejudice or limitation describe my
invention as applied to a scutching apparatus in which the laps rest upon a
travelling lattice. Three such laps being a convenient and usual number.
well known the laps after being formed have usually the core upon which they are
wound removed and replaced by a smaller rod the projecting ends of which extend
through bearing slots in the side frames. By the traversing lattice the laps are
unrolled and fed to the scutcher. It will be apparent that if one of the lap rolls
should become exhausted the quantity of cotton fed to the scutcher is diminished
and the quality of the work impaired by the thinning of the work caused by this
exhaustion of one of the laps being technically known as "single." The object
i

page_text: of my invention is to prevent this, and I have therefore devised an improved stop
motion which is or may be constructed and arranged as follows. In the first
place I may point out that as the laps roll diminishes in circumference the
centre or core rod is lowered in the bearing slots. I form an extension on
one end of each lap rod, which forms a suitable handle as well as a weight
to the rod, and at the foot of the slot I pivot a bell crank lever, the
upper horizontal arm of which lies directly in the path of the centre rod as it
descends along the side of the frame, and just below the slot bearings there is in
certain ordinary types of scutchers a side shaft to connect and drive the shafts and
carrying discs at each end of the lattice, upon this revolving side shaft I fix a
bevel wheel which gears with another bevel wheel running loosly on the end of a
swinging bracket hung or centred loosly on the shaft. Behind the fixed bevel
wheel a third bevel wheel mounted loosly on the side shaft gears with the second
bevel wheel so that under normal circumstances all three wheels revolve freely. On
the back of the third wheel, which as I have said is loosly mounted on the shaft,
I place one or more projections, and on the bell crank lever I place a finger,
opposite to these projections and in such a position that if the bell crank lever
should be moved the finger will come against one of these projections and stop the
revolution of the loose bevel wheel. As the second bevel wheel on its suspending
bracket would still be revolved by the fixed bevel wheel on the side shaft, it follows
that the stoppage of the third bevel wheel in the manner described would cause the
second bevel wheel with its loosly pivoted bracket to be carried round the side.
shaft. Formed on or attached to the boss of the said suspending bracket there is a
pulley having wound upon it a cord with an attached weight. The carrying round
of the bracket and bevel wheel also effects the rotation of this pulley so as to wind
on the cord and raise the weight. On the back of the pulley there is a projection
which lies in the path of a projection extending from one side of a washer mounted
loosly on the shaft, the other side of the washer also carrying a projection lying
in the path of another washer with a projection lying in the path of a tooth
extending from a second pulley or boss mounted loosly on the side shaft, and in
line with the first. The first pulley in rotating with the pivoted bracket strikes
the projections on the washer as it is carried round. This washer also strikes a
second washer and moves it round. This second washer as a projection which
comes in the path of a tooth which projects from the second pulley and is carried
round by the second washer. From this last pulley or boss I actuate the stop
lever. And this is effected in any suitable manner to meet the circumstances of
each particular case. For instance a cord might be wound on the second pulley or
boss and connected to the strap lever, or a lever might extend from the boss and
operate the strap fork, or other means used to arrest the motion of the machine.
A gong or bell might be connected to any of the parts to give warning to the
attendant of the stoppage of the machine. The reason of the dwell between the
first and second parts of the stop motion as described is to give a time between
the moment when the lap rod touches the bell crank lever and the actual stopping
of the machine, this being arranged to provide for the excentric position of the lap
rod in the central larger hole in the lap roll. Where there are several lap rolls it
is only necessary to provide one such mechanism as described for one lap roll the
other laps having their bell crank levers connected thereto by a side rod connected
to the tails of all the bell crank levers. When the empty lap rod is removed the
loose bevel wheel is released and the weight on the first pulley falls replacing the
parts in their normal position ready for being again actuated. Where the aforesaid
side shaft does not exist a short auxiliary shaft can be applied to the side frame.
I do not limit myself to the exact construction and disposition of parts set forth as
these might be modified without departing from the spirit of my invention.
instance a clutch box might take the place of the three bevel wheels, and be
actuated from the bell crank levers. In some cases electricity might be used to
actuate the bell crank levers.
For
I will now describe the working of my invention by the drawing which is a side

page_text: elevation of the feed part of a scutcher. The lap rod I falls in the slots as the
lap roll decreases in size and on reaching the bottom of the slot they press down
the bell crank levers 2. The finger 3 on the bell crank levers is brought against
the projections on the boss of wheel 4 and stops its rotation which causes the
loosly pivoted bracket with its bevel wheel 5 to revolve round the shaft through
the motion given to it by the revolving of the fixed wheel 6. The arm 7 revolves
the pulley 8 which windes up the weight. The finger on the pulley 8 comes in
contact with the projection on the washer 9 on this washer there is a projection
which comes in contact with a projection on another washer 10 on this washer is
another projection which in its revolution comes in contact with a finger on the
loose pulley 11. This loose pulley draws the strap fork of the machine on to the
loose pulley and stops the machine. When the lap rod is removed the weight falls
and in doing so puts all the mechanism to its normal position again.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. The automatic stopping of the scutcher by the action of the lap rod.
2. The alteration of lap rod so as to form a handle and weight combined.
3. That the removal of the lap rod from the slots will allow the mechanism to
return to its normal position agaiu, and in so doing will allow the scutcher to be
recommenced.
