PROVISIONAL SPECIFICATION.
Improvements in or connected with Feeding Machines of Cotton
Openers and Cleaners.
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:-
This invention comprises
Firstly. Improvements in the construction of parts of the feeder whereby
increased efficiency and better result as to removal of dirt and grit is ensured before
the cotton passes from the feeder.
Secondly. Improved construction and combination of mechanism for simultaneously
stopping the feeding machine when the cotton opener stops on completion of
each "lap."
Thirdly. Improved means for operating the spikes or pins of the strickle roller
working in conjunction with the spiked lifter sheet or apron of said machine.
According to this my said invention instead of the cotton being passed from the
beater casing over or above a cage to the stripper rollers the bottom of the casing
is extended from the cross bar grating so as to form (preferably) an inclined plane
consisting of longitudinal or transverse bars constituting a grid or grating along
which the cotton is drawn so as to pass to and between two cages arranged one
above the other whereby the utility of the feeding machine as to the removal of
objectionable matter from the cotton preparity to its being passed to the opener or
cleaner is greatly increased.
The improvements for connecting and controlling the driving mechanism of the
hopper feeder machine, and the opener and cleaner, comprises an arrangement of
levers, operated by the ordinary "drop levers" of the opener and cleaner, said
levers in turn operate a shaft and clutch box, connected with the gearing for driving,
the going parts of the feeder machine, so that when the opener and cleaner "knocks
off" at completing of each "lap" motion is communicated by the connections
referred to, and the clutch box is thrown out, stopping the going parts of the feeder
machine, until feeder and cleaner is restarted.
The improved apparatus for operating the spikes or pins by protruding same for
removing or strickling surplus fibre from the feed sheet, and for withdrawing the
said spikes or pins into the said roller, so as to keep them from fouling the fibre
in the hopper during the remaining portion of its revolution is as follows:-
The
The strickle roller is mounted in bearings at each end and revolves around its
centre shaft which is stationary and on which shaft are fixed two cams.
strickle roller has cross bars fixed to it which revolve with said roller, and these
cross bars carry the spikes or pins which are fixed on the outer edges and on the
inner edges of each of the cross bars I mount a small bowl or runner carried in
brackets. The cross bars are free to slide in radial slots formed in the ends of the
roller, and the bowls or runners are kept in contact with the cams by means of
spiral springs attached to the opposite cross bars so that as the roller revolves and
the bowls or runners pass over the full sides of the cams the spikes or pins are
protruded, and when passing over the opposite and narrow faces of the cams the
spikes or pins are withdrawn by the action of the spiral spring.

Openers and Cleaners.
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 :-
This invention comprises
Firstly. Improvements in the construction of parts of the feeder whereby
increased efficiency and better result as to removal of dirt and grit is ensured
before the cotton passes from the feeder.
Secondly. Improved construction and combination of mechanism for simultaneously
stopping the feeding machine when the cotton opener stops on completion of
each "lap."
Thirdly. Improved means for operating the spikes or pins of the strickle roller
working in conjunction with the spiked lifter sheet or apron of said machine.
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,
in which :-
Fig. 1 is a side elevation of the feeding machine, shewing part of the driving
gear and apparatus for controlling clutch.
Fig. 2 is a longitudinal sectional view of Fig. 1.
Fig. 3 is a view of the levers for controlling the hopper feeder.
Fig. 4 is a longitudinal sectional elevation of part of strickling device and
apparatus for operating same, the spiral springs being removed in order more
clearly to shew its construction.
Fig. 5 is an end view of Fig. 4 shewing one of the spiral springs in position.
According to this my said invention instead of the cotton being passed from the
beater and casing 1ª over or above the cages 2 to the stripper rollers 3 3, the
bottom or grating 4 of the casing 1 is extended in (preferably) an inclined
plane 5 consisting of longitudinal or transverse bars constituting a grid or grating 5
along which the cotton is drawn so as to pass to and between two cages 2, 2
arranged one above the other whereby the utility of the feeding machine as to the
removal of objectionable matter from the cotton preparatory to its being passed to
the opener or cleaner is greatly increased; 6 is a dirt box below the grid or
grating 5 and into which dirt from the cotton falls.
The improvements for connecting and controlling the driving mechanism of the
hopper feeder machine (see Fig. 3) comprises a clutch 7 on the driving shaft 8,
said clutch being controlled and slided in or out of gear by a fork 9 fixed on the
vertical shaft 10 to the lower end of which is fixed a short lever 11 attached to the
horizontal rod or shaft 12 underneath the feeder. This shaft 12 is connected to
the short lever 13 fixed on the top of the shaft or rod 14, which passes through the
floor to the scutcher machine (or along the floor when the machines are on the same
plane) and at the lower end of the rod 14 is fixed the lever 15 connected to the
link and lever 16 operated by the ordinary drop lever 17 of the scutcher.
When the drop fever 17 falls or is lowered to stop the scutcher, it operates the
lever 16, which gives a partial turn to the levers 15, shaft or rod 14, lever 13;
shaft 12, lever 11, shaft 10, and fork 9, and the latter moves and disconnects the
clutch, and stops the feed.
The improved apparatus for operating the spikes or pins 18 (see Figs. 4 and 5)
by protruding same from the roller 20 for removing or strickling surplus fibre from
the feed sheet 19, and for withdrawing the said spikes or pins 18 into the said

page_text: roller 20, so as to keep them from fouling the fibre in the hopper during the
remaining portion of its revolution is as follows:-
The strickle roller 20 is mounted in bearings at each end, and revolves around
its centre shaft 21, which is stationary, and on which shaft are fixed two cams or
tappets 22, one near each end of the shaft 21. The strickle roller 20 has cross
bars 23 fixed to it which revolve with said roller 20, and these cross bars 23 carry
the spikes or pins 18 which are fixed on the outer edges of said cross bars, and on
the inner edges of each of the cross bars is mounted a small bowl or runner 24
carried in brackets 25. The cross bars 23 are free to slide in radial slots or
grooves 26 formed in the ends of the roller 20, and the bowls or runners 24 are
kept in contact with the cams or tappets 22 by means of spiral springs 27 attached
to the opposite cross bars 23, so that as the roller 20 revolves, and the bowls or
runners 24 pass over the full sides of the cams or tappets 22, the spikes or pins 18
are protruded, and when passing over the opposite and narrow faces of the cams or
tappets 22, the spikes or pius 18 are withdrawn by the action of the spiral
springs 27.
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.) In machines for purpose set forth the feed sheet 19, beater 1 and gratings 4
and 5, and cages 2, 2, all in combination, and as illustrated by annexed drawings.
(2.) The improved appliances and means described herein and illustrated by
Figs. 4 and 5 for operating the spikes or pins 18 in combination with a feed
sheet 19, and for purpose herein set forth.
(3.) In machines for purpose described and as claimed in above claiming clauses
the use and employment of a device constructed and as illustrated by Fig. 3, for
connecting and controlling said machine from and by the "opener" or "scutcher"
as herein fully described, and for purpose set forth.
