PROVISIONAL SPECIFICATION.
Improvements in Machines for Opening and Scutching Cotton and
other Fibre.
We, WILL LORD, of the Firm of Lord Brothers, of Canal Street Works,
Todmorden, in the County of York, Machine Makers, and FREDERICK
WOODHEAD, of the same place Draughtsman, do hereby declare the nature of
this invention to be as follows:-
Our invention is applicable to those opening and scutching machines in which a
hopper feed is employed with the ordinary feed apron, and the object of our inven-
tion is to stop and start the hopper feed automatically, when a full lap of fibre is
removed from the machine; and this we effect by means of apparatus connected
to the ordinary mechanism by which the feed apron is automatically stopped when
a full lap of fibre is broken off, and removed from the machine and re-started when
a new lap is begun.
In one arrangement we mount on the driven feed apron roller shaft a bevel
wheel which gears into and drives a bevel pinion secured on a shaft carried in a
suitable bearing, on this shaft is cut a square or other screw thread and fitted on
the shaft is a small flywheel carrying a peg or stud which engages with the screw
on the shaft; the boss of this flywheel is grooved and receives the ends of a pivoted
lever connected by rods and levers to the strap fork which governs the driving
belt of the hopper feed.
When the machine is in operation the flywheel is in such a position on the
screwed shaft as to hold the driving belt on the fast pulley of the hopper feed,
but as soon as a lap is full and it is removed from the machine the feed apron is
automatically stopped by the usual mechanism; the stoppage of the feed apron
roller shaft stops the screwed shaft but the inertia of the flywheel causes it to
travel along the shaft and thereby, by the rods and levers, move the strap fork and
shift the belt from the fast to the loose pulley and so stop the hopper feed.
As soon as the machine and feed apron are again set in motion the screwed shaft
is also set in motion and it thus causes the flywheel to traverse along it in the
reverse direction and shift the belt from the loose to the fast pulley and re-start
the hopper feed.

Improvements in Machines for Opening and Scutching Cotton and
other Fibre.
We, WILL LORD, of the Firm of Lord Brothers, of Canal Street Works,
Todmorden, in the County of York, Machine Makers, and FREDERICK
WOODHEAD, of the same place Draughtsman, 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 :-
Our invention is applicable to those opening and scutching machines in which a
hopper feed is employed with the ordinary feed apron and the object of our inven-
tion is to stop and start the hopper feed automatically and this we effect by means
Die 17

page_text: of apparatus connected to the ordinary mechanism by which the feed apron is
automatically stopped when a full lap of fibre is broken off and removed from the
machine, and re-started when a new lamp is begun.
And in order that our invention may be fully understood and readily carried into
effect we will describe the accompanying four sheets of drawings reference being
had to the figures and letters marked thereon.
Figs. 1 and 2 are side elevation and plan view repectively of part of the end of
an opening or scutching machine for cotton and other fibre, to which our automatic
stopping and starting motion is applied.
Figs. 3, 4 and 5 are side elevation, plan view and end view respectively of our
automatic stopping and starting motion applied to the hopper feed, and also to the
feed roller, the mechanism being set in action from the machine when it is stopped
for the removal of a full lap or other purpose.
In Figs. 1 and 2, is the ordinary feed roller of a travelling feed apron, not
shown, and on the axle of this roller is keyed a spur wheel a¹; a pair of driving
pulleys bare mounted upon a stud c secured to the machine or hopper frame and
a pinion keyed on the boss of the fast pulley gears into and drives the
wheel a', and by it the feed roller a; the pinion e' also gears into and drives a
spur pinion on a stud d which carries a chain wheel 2, around which a chain d
is passed and conveys motion to a chain wheel el secured upon a stud e carried in a
bracket bolted to the machine frame.
The stud e has a screw thread cut upon it and on the threaded portion is fitted
loosely a fly wheel which has a pin g fitted in its boss, projecting into the
thread. The boss of the flywheel g is also grooved at 92, and in this groove is
fitted a bowl / carried at one end of a lever h, mounted upon a stud ³, carried in
the bracket; on this stud is another lever to a stud on which is connected
a rod i which runs alongside the machine frame to the strap fork of the hopper.
feed, neither the strap fork nor the hopper is shown in the drawings.
The operation is as follows:-
When the fast pulley is in motion the feed roller a is driven by the spur
wheels c' and a', and by the spur wheel d¹ and chain d³ motion is conveyed to the
chain wheel e¹, and stud e, the rotation of which by means of its threaded portion
acting on the pin g' keeps the loose flywheel g in the position shown in Fig. 2, and
so the levers and rods i in connection with the bowl ' maintain the strap on the
driving pulley of the hopper feed. When the belt or rope for driving the feed
roller is stopped the feed roller a chain d' and the stude are all brought to a
standstill but the momentum of the flywheel g carries it forward while the stud g
in the screw thread of the stud e travels in the thread and so draws the flywheel
laterally toward the chain d', while the bowl h¹ in the groove of the boss moves the
lever stud, lever and starting rod i, thereby removing the driving belt on the
hopper feed, not shown, from the fast to the loose pulley and stopping the feed.
In like manner when the feed roller a is re-started and the stud e is again
rotated the inertia of the flywheel g causes it to be moved back by the rotation
of the screw laterally into the position shown in Fig. 2, and the bowl h¹ moving
with it the levers and connections move the rod i and so actuate the strap fork
which automatically re-starts the hopper feed.
In Figs. 3, 4 and 5, the mechanism for driving the threaded stude on which the
flywheel g is mounted is not shown, the feed roller a has mounted loosely upon its
axle a worm wheel k which driven by a worm / upon the driven cone shaft ",
see Fig. 4; a sliding clutch box m is mounted upon a feather key in the axle of
the feed roller a, the wheel k forming the other half of the clutch, the parts being
held in gear by a spring k¹ or otherwise, the boss of the clutch box m is grooved
at m' and one edge of the groove has four notches cut in it.
The boss of the flywheel g is connected to e as before described; in the groove g³
of the boss is fitted a bowl carried at one end of a lever h mounted upon a
stud 2, carried in a bracket f; on this stud is another lever to a stud in which
is connected a rod i which actuates the strap fork of the hopper feed not shown.

page_text: The lever is also connected by a rod to a lever n fixed upon a stud o to
which is also secured a lever n', connected by a rod p to a lever q, on which is.
mounted a bowl q², the lever is pivoted at g' to a bracket r carried by the frame.
When the machine is in operation the flywheel g occupies the position as
described in reference to Figs. 1 and 2, as soon however as the opening or
scutching machine is stopped to remove a full lap or for other purpose, the stud e
comes to a stand and the movement of the flywheel along it moves the lever h
stud and lever ³, thereby traversing the rod i and moving the strap fork so as
to shift the belt from the fast to the loose pulley on the hopper feed, and stopping
the feed of fibre to the machine; the movement of the lever h³ at the same time
moves the rod the levers n n' and rod o so as to draw down the lever and
thus bring its bowl q* into the groove m' of the sliding clutch box m, the notches
in which act upon the bowl and draw the teeth in m from those in the worm
wheel k and thereby stop the rotation of the feed roller a.
When the opening or scutching machine is re-started the flywheel 9 moves the
lever in the reverse direction and by the means described sets the hopper feed
in motion and at the same time the lever g is raised and brings its bowl q out of
the clutch box m, when the spring k¹ acting upon an elbow levers moves the
clutch m into gear with the worm wheel k and starts the feed roller a which delivers
fibre to a beating cylinder t from which it passes into a trunk connected to the
opening or scutching machine, or direct to the machine as arranged.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In mechanism for automatically stopping and starting the feed of openers and
scutchers the arrangement use and application of a flywheel mounted loosely on a
rotating screw driven from the opener or scutcher said flywheel by its inertia
actuating the driving mechanism of the hopper feed substantially as herein set
forth.
2. In mechanism for automatically stopping and starting the feed of openers and
scutchers, the arrangement use and application of a flywheel mounted loosely on a
rotating screw driven from the opener or scutcher, said flywheel by its inertia
actuating the driving mechanism of the hopper feed and the feed roller substantially
as herein set forth.
3. The general construction combination and arrangement of parts forming the
improved automatic stopping and starting motion as and for the purposes described.
