IMPROVEMENTS IN MACHINES FOR OPENING, AND SCUTCHING COTTON to be as follows
Year: 1884

page_text: I SAMUEL TWEEDALE, of Globe Works, Accrington, in the County of Lancaster,
Manager, do hereby declare the nature of my said invention for "IMPROVEMENTS
IN MACHINES FOR OPENING, AND SCUTCHING COTTON to be as follows:-
"
"
The object of this my invention is, that when the feed motion, of machines for
purpose aforesaid, is stopped or "knocked off," the "lap" motion shall be continued,
until the cotton, then in the cleaning boxes or trunk," shall be withdrawn
therefrom, as, distinguished from machines, as heretofore constructed, and used,
wherein the "feed," and "lap," motions, are stopped simultaneously, cotton being
left within the length of the trunk, to which there are several obvious objections.
For purpose aforesaid, in combination with the ordinary knocking off appliance,
I employ link, clutch box, and pin motion, similar to the well known "Parrs
motion or "space wheel motion" employed on mules for spinning fibres-the
latter motion, is connected, 'and combined, with a fork, and clutch box motion,
on shaft of pinion, which gears with, and drives the spur wheel, on the axis or
shaft of the bottom calender roller, and through this apparatus, the lap motion will
be continued, after the feed, (which is driven from independent source,) is stopped,
the lap motion continuing, until the cotton is exhausted, or withdrawn from the
trunk, to the cages, whereon the clutch is thrown out-On restarting, there will
not be any cotton in the trunk, the further supply being taken direct from the feed
end of the machine-The clutch box motion is thrown into gear, by means of a
spiral spring or weight-and the timing the action of the apparatus, is effected by,
means of change wheels.

I SAMUEL TWEEDALE, of Globe Works Accrington, in the County of Lancaster,
Manager, do hereby declare the nature of my said invention for "IMPROVEMENTS
IN MACHINES FOR OPENING AND SCUTCHING COTTON and, in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
The object of this my invention is, that when the feed motion, of machines for
purpose aforesaid, is stopped or "knocked off," the "lap" motion shall be continued,
until the cotton, then in the cleaning boxes or "trunk" shall be withdrawn
therefrom, as distinguished from machines, as heretofore constructed and used,
wherein the "feed" and "lap" motions, are stopped simultaneously cotton being
left within the length of the trunk to which there are several obvious objections.
Such being the nature and object of my 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 part of a machine for scutching and opening cotton
having my improvements applied. thereto-Fig. 2 is an end elevation of same-
Fig. 3 is a detail of cam for operating clutch box hereinafter described.
At 1. 2. 3 are link clutch box and pin motion similar to the well known Parrs
change motion as applied to mules and to which' I make no special claim, combined
with which is a fork 4-At 5 is a clutch box on shaft 6. At 7 is pinion gearing
with wheel 8 on shaft 9 of the bottom callender roller 10-At 11 is a finger
on opposite end of the shaft of the fork 4-At 12 is a cam which operates the
finger 11 for moving the clutch 5 in and out of gear-At 13 is the ordinary drop
lever mounted on fulcrum pin 14, but the end of this lever is extended and carries
the wheel 15, and rope pulley 16, the latter drives the ordinary "feed"-the
wheel 15 is driven by the wheel 17, the latter having continuous motion from the
beater"-18 is, a connecting rod, connecting the drop 'lever 13 and Parrs motion
or parts 1. 2. 3-At 19 is a stud on which the rod 18 is carried-At 20 is a pinion
gearing with wheel 21. 22 is a change wheel by means of which the speed of
the Parrs change motion is varied. 23 is a gear wheel driving the shaft 24 of the
clutch box 2.

The action of the apparatus is as follows:-
-
Assuming the machine in operation and it is desirable to arrest its motion the
lever 13 will be dropped whereon the wheel 15 will be removed out of gear with
the pinion 17 the pulley. 16 and its driving rope are thus likewise stopped and so
is the "feed" part meanwhile the cages and lap motions are continued until the
cam 12 has completed its half revolution and the incline 25 has raised the finger 11
and by means of the fork 4 thrown the clutch box 5 out of gear, during the time
the cam 12 is making its half revolution as just referred to the cotton will have
been withdrawn from the trunk and passed forwards to the cages.
When to start the machine the lever 13 is lifted the wheel 15 will be in gear
with its driving wheel 17 and the rope pulley 16 will start and drive the "feed"
the stud 19 at the time of lifting the lever 13 will start the Parrs change motion 1. 2. 3

page_text: and the finger 11 working on the cam 12 will prevent the clutch box 5 taking into
gear until the cam 12 by the incline 26 allows the clutch box spring 27 to expand
and put the clutch in gear.
During the time the cam 12 is making this half its revolution the lap part is
stopped and the "trunks" are again filling with cotton.
According to the length of trunk employed so will the change wheel 22 be varied
and adapted:
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
"
The apparatus such as herein described and illustrated, whereby, when the feed
motion is stopped, the cage and lap motions are continued until the cotton is
removed or withdrawn from the trunk, and on restarting, the feed motion will
operate, earlier than the lap motion so as to give the requisite supply of fibre to the
cages by time the latter commence running.
