Improvements in or relating to Cotton Openers or Scutchers.
I, LAYCOCK HARGREAVES, of Globe Works, Accrington in the County of
Lancaster, Manager, do hereby declare the nature of this invention to be as
follows:-
In the working of scutchers the feed is usually at a distance from the opener or
scutcher the intervening length of trunk being occupied by cotton. It is the design
of this invention by improved appliances hereinafter described to continue the
working of the opener for a period of time, after the feed has been stopped,
sufficiently long to use up the cotton in the intervening length between the feed and
the opener, and when resuming working, the feed shall be started so long before the
opener, that the feed will have supplied sufficient fibre, to fill the trunk, or length
between the feed, and the opener, before the latter is restarted.
21
Apparatus for purpose aforesaid according to this my invention comprises the
usual arrangement of driver pinion and toothed plate wheel on the bottom callender
roller said plate wheel being loose on its shaft and having a "nug or driving
piece on its boss. Fast on the said shaft is a collar having a corresponding driving
piece so that the plate wheel makes nearly a loose revolution and so long therefore
does not move the callender roller, and such plate roller can be caused to move
loosely on its shaft, one or more complete revolutions, by the use of additional
collars, and driving pieces, placed on axis of callender roller and between the boss
of the plate wheel, and the fast or driving collar above mentioned.

In connection with the stop motion are two stop levers and also duplicated
pointers one of the latter to act in conjunction with the stop motion of the
"feed" the other to act in conjunction with the stop motion of the "
scutcher."

The first pointer operates and through the connections the "feed" is stopped but
the opener or scutcher continues to run and work, until the second pointer acts on
the connections of the stop lever motion of the opener or scutcher the interval
between stopping the feed and the opener or scutcher being sufficient to admit of
the cotton in the trunk being used up or carried into the opener or scutcher. So
likewise on restarting the feed will first move, and supply fibre enough to fill the
intervening length of trunk, between the feed and the opener before the latter is
started the requisite variation in time of starting the "feed" and the opener or
scutcher being adjusted according to the distance between the two by means of one
or more collars and driving pieces on the shaft of the callender roller above
described.
There is a volute spring in conjunction, with the toothed plate wheel which is
coiled and charged when the latter is rotating in its working direction the power of
said spring is utilized for reversing or turning back the plate wheel so as to be ready
to run loosely on its shaft before next starting the machine and in order to moderate
the speed of rotation of said wheel on its backward motion a brake or brake spring
is applied thereto.

Improvements in or relating to Cotton Openers or Scutchers.
I LAYCOCK HARGREAVES of Globe Works, Accrington in the County of
Lancaster 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 :-
In the working of scutchers the feed is usually at a distance from the opener or
scutcher the intervening length of trunk being occupied by cotton. It is the design
of this invention by improved appliances hereinafter described to continue the
working of the opener for a period of time after the feed has been stopped
sufficiently long to use up the cotton in the intervening length between the feed and
the opener & when resuming working the feed shall be started so long before the
opener that the feed will have supplied sufficient fibre to fill the trunk or length
between the feed and the opener before the latter is restarted.
Apparatus for purpose aforesaid according to this my invention comprises the
usual arrangement of driver pinion and toothed plate wheel on the bottom callender
roller said plate wheel being loose on its shaft & having a "nug" or driving piece
on its boss. Fast on the said shaft is a collar having a corresponding driving piece
so that the plate wheel makes nearly a loose revolution & so long therefore does not
move the callender roller and such plate wheel can be caused to move loosely on its
shaft one or more complete revolutions by the use of additional collars and driving
pieces placed on axis of callender roller and between the boss of the plate wheel and
the fast or driving collar above mentioned.
"C
In connection with the stop motion are two stop levers and also duplicated
pointers one of the latter to act in conjunction with the stop motion of the
"feed"the other to act in conjunction with the stop motion of the "opener or
scutcher."
There is a volute spring in conjunction with the toothed plate wheel which is
coiled & charged when the latter is rotating in its working direction and the power
of said spring is utilized for reversing or turning back the plate wheel so as to be
ready to run loosely on its shaft before next starting the machine & in order to
moderate the speed of rotation of said wheel on its backward motion a brake or
brake spring is applied thereto.
Such being the nature and object of my said invention the following is a complete
description of same reference being had to the accompanying drawings forming a
part of this Specification in which:-
Fig. 1. is a side elevation of my improved appliances connected with cotton
openers or scutchers.
Fig. 2 is a plan view of part of Fig. 1.
Fig. 3 is a plan view in section of the plate wheel, and the mug, and fast and
loose collars.
Fig. 4 is a side elevation of stop lever or handle detached.
According to this my said invention the improved apparatus comprises the usual
arrangement of driver 1 and toothed plate wheel 3 on the axis of the bottom
callender roller 4 the said plate wheel 3 being loose on its shaft 5 and having a nug
or driving piece 6 cast, on its boss. Fast on the said shaft 5 is a collar 7 (see
Fig. 3) having a corresponding driving piece or nug 8 which comes in contact with
the nug 9 on the collar 10 loose on the boss of the fast collar 7 and the nug or
driving piece 9 comes in contact with the nug 6 on the plate wheel 3 so that the
plate wheel 3 makes nearly two loose revolutions before driving or turning the
callender roller 4 and such plate wheel 3 can be caused to move loosely nearly one
revolution if only one fast collar is employed, and nearly two loose revolutions if
fast and loose collars are used as shewn by Fig. 3 or by the use of additional
collars and driving pieces, placed on the axis of the callender roller 4 and between
the boss of the plate wheel 3 and the fast or driving collar above mentioned.

In connection with the stop motion are one or more step levers 11-12 one of
such levers 11 being mounted on a fulcrum stud 13 and its upper end carries a
toothed wheel 14 gearing with and driven by the wheel 15 on the top callender
roller 16 and as one of the notched pointers 17 on the wheel 15 meets one of the
pointers 18 on the wheel 14 the latter is forced away from the wheel 15 and the
lever 11 turns on its fulcrum stud 13 and the finger 17 on the lower end of
the lever 11 presses against the end of the slide 18 moving the latter so that. its
holding catch is moved out of the holding notch 19° (sec Fig. 4) in the lever 12
and the lever 19 falls by gravitation moving on its fulcrum stud 20 to the rest 20"
which prevents its falling too far but so far that the cranked arm or part 21 of the
lever 19 on which is carried the grooved pulley 22 and driven wheel 23 is moved
out of gear with the driving pinion 24 and the "feed" of the machine is stopped.
When the lever 19 falls the beak 25 pressing on the end of the lever 26 moves the
Intter on its fulcrum 27 and the end 28 forces the slide 29 along its rest 30 in the
lever or stop handle 12 so that the end of the slide 29 is moved out of its holding
notch 30 in the bracket 30° and the handle or lever 12 will fall by gravitation as
soon as the lever 11 presses against the stud 31 and moves the slide 32 from off the
holding notch 33 and this takes place when the second of the notched pointers 17
and pointers 18 meet the lever 11 being turned a little more on its fulcrum 13 by
the second pointers being rather longer.
The pointers 17-18 are mounted on wheels 14-15 of different diameters, so
that they will meet and come into contact with a predetermined number of
revolutions.
When the stop handle or lever 12 falls it moves on its fulcrum or centre 20 and
carries with it the driver 1 which is mounted thereon and moves the said driver out
of gear with the plate wheel 3 and stops the machine.
When the lever 12 falls the catch 18 comes back into the notch 19" so that as the
lever 12 (when restarting the machine) is lifted the slide or catch 18 is also lifted
the spiral spring 18" forcing the side or catch 18 into the said holding notch 195.
There is a volute spring 35 in conjunction with the toothed plate wheel 3 which
spring is coiled and charged when the wheel is rotating in its working direction the
power of said spring 35 being utilized for reversing or turning back the plate
wheel 3 so as to be ready to run loosely on its shaft before next starting the machine
and in order to moderate the speed of rotation of said wheel 3 on its backward
motion a brake or brakes spring 36 is applied thereto.
The first of the pointers 17 operates and through the connections the "feed" is
stopped but the opener or scutcher continues to run and work until the second of
the pointers 17 acts on the connections of the stop lever motion of the opener or
scutcher the interval between stopping the feed and the opener or scutcher being
sufficient to admit of the cotton in the trunk being used up or carried into the
opener or scutcher. So likewise on restarting the feed will first move and supply
fibre enough to fill the intervening length of trunk between the feed and the
opener before the latter is started the requisite variation in time of starting the
"feed" and the opener or scutcher being adjusted according to the distance between
the two by means of one or more collars and driving pieces on the shaft of the
callender roller above described.
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 general construction arrangement and combination of mechanism for
purpose aforesaid as herein described and substantially as illustrated by Fig. 1 of
the accompanying drawings.
