PROVISIONAL SPECIFICATION.
for Opening and Preparing
mprovements in Hopper Feeders
Machines for Cotton and other Fibres.
We, WILL LORD, of the Firm of Lord Brothers, of Canal Street Works, Todmorden.
n the County of York, Machine Makers, and FREDERICK WOODHEAD, of the same
lace, Draughtsman, do hereby declare the nature of this invention to be as
ollows:-
Our invention relates to improvements in hopper feeders for opening and preparing
machines for cotton and other fibres and the chief object of our improvements is to
regulate the amount of fibre which passes over the top of the inclined needle lattice in
the hopper by the amount of fibre which passes under the spoon ends of the pedals of
the piano feed, or by the amount of fibre that passes on to the feed lattice of the
opening or other machine.
In carrying our invention into effect we prefer to employ a fixed but adjustable
board with a flexible edge which passes across the hopper, the flexible edge being
set a few inches from the inclined lattice and placed preferably a short distance below
the ordinary spiked evening roller.
The chief feature of our invention consists in placing a pressor roller or equivalent
inside the inclined lattice and supported in bearings on pivoted weighted levers placed
outside the hopper. One end of one of these weighted levers is connected by a rod
say to one end pendant of the piano feed of an opening machine and a second rod
on the other end of the piano feed is connected to the other weighted lever.
The action is as follows:-
When a lump or too much fibre is passing under the spoon ends of the pedals,
the pendants are moved outward and by this movement the rods are moved so as
to draw down one end of each weighted lever and thereby bring the presser roller
against the inside of the inclined lattice and move it nearer to the spiked evening
roller and so reduce the amount of fibre passing up over the inclined lattice.
When there is too little fibre passing between the pedal feed the rods and
weighted levers are raised which moves the presser roller from the inclined
lattice and allows more fibre to pass up between it and the spiked roller.
This arrangement may be used with or without the cones for regulating from the
piano feed.
In another arrangement we dispense with the connection to the piano feed and
employ a roller and a pivoted trough adjusted and set at any suitable distance
apart and placed above the lattice feed; the fibre falls from the inclined lattice over
a plate on to the trough and passes between it and the roller; when an excess of fibre
passes under the roller the trough is moved on its pivot and by suitable connections
actuates the weighted levers and so moves the presser roller and the inclined lattice
nearer to the spiked roller and thus diminishes the quantity of fibre passing over
the top of the inclined lattice.
In place of the roller and trough a pair of rollers one in fixed, and the other
in pivoted and adjustable, bearings could be employed to regulate the amount of
fibre passing between the inclined lattice and spiked roller.

page_text: Improvements in Hopper Feeders for Opening and Preparing
Machines for Cotton and other Fibres.
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
sind by the following statement:-
Our invention relates to improvements in hopper feeders for opening and preparing
machines for cotton and other fibres and the chief object of our improvements is to
regulate the amount of fibre which passes over the top of the inclined needle lattice in
the bopper by the amount of fibre which passes under the feed roller and over the spoon
ends of the pedals of the piano feed, or by the amount of fibre that passes on to the
feed lattice of the opening or other machine.
In carrying our invention into effect we prefer to employ a fixed but adjustable
board with a flexible edge which passes across the hopper, the flexible edge being
set a few inches from the inclined lattice and placed preferably a short distance below
the ordinary spiked evening roller.
The chief feature of our invention consists in placing a presser roller or equivalent
inside the inclined lattice and supported in bearings on pivoted weighted levers placed
outside the hopper. One end of one of these weighted levers is connected by a ro
say to one end pendant of the piano feed of the opening machine and a second rod
on the other end of the piano feed is connected to the other weighted lever.
In another arrangement we dispense with the connection to the piano feed and
employ
a roller and a pivoted trough adjusted and set at any suitable distance apart
and placed above the lattice feed; the fibre falls from the inclined lattice over a plate
on to the trough and passes between it and the roller.
In place of the roller. and trough a pair of rollers one in fixed, and the other in
pivoted and adjustable, bearings, could be employed to regulate the amount of fibre
passing between the inclined lattice and spiked roller.
In the accompanying two sheets of drawings-
Figure 1 is a sectional side elevation, and Fig. 2 an end elevation of our
improved regulating mechanism applied to a combined hopper and piano feed in an
opening machine.
Figure 3 is a sectional side elevation of two alternative arrangements with a
delivery roller and trough or pair of delivery rollers respectively in place of the
piano feed regulator.
In Figures 1 and 2, a designates the hopper, b the travelling bottom lattice,
e the travelling inclined needle lattice, d the spiked evening roller, e the stripper for
clearing the evening roller, the stripper for clearing the needle lattice, g the sheet
iron or other delivery plate, h the delivery roller, i the feed lattice, the feed roller,
k the beater, the pedals or spoon endel levers, m the pendants or fish tailed levers,
n the rods and levers for connecting the pendants to the strap fork guide lever o,
and p the pair of cones for driving the feed roller j.
All the foregoing parts are of the usual construction and their arrangement and
mode of operation is well understood.
For the purposes of our invention we employ an adjustable laying or evening
board q with a flexible edge q' said board being fixed across the hopper preferably
a short distance below the evening roller d and with its flexible edge q' parallel to
and a few inches from the inclined needle lattice c. Inside the needle lattice c
and nearly opposite the flexible edge q¹ of the laying board 9 we place a pressing
roller which is supported in bearings in levers fulcrummed to the frame at

page_text: weighted at and at the other ends connected by rods t to the levers a and so to the
pendants m.
In operation, when a lump or too much fibro is passing over the spoon ends of
the pedals 1, the pendants m are moved outward and regulate the speed of the feed
roller in the ordinary way and simultaneously by this movement the rods are moved
o us to draw down one end of each weighted lever and thereby bring the pressing
roller against the inside of the inclined needle lattice c and move it nearer to
the spiked evening roller d and so reduce the amount of fibro passing up over the
inclined noodle lattice c..
When there is too little fibre passing between the pedals 7 and the feed roller j
the rods and weighted levers & are raised which moves the pressing roller raway
from the inclined needle lattice c and allows more fibre to pass up between it and
the spiked evening roller d.
This arrangement may be used in combination with the cones p, as shown and
described, for regulating the speed of the feed roller j or the cones may be dispensed
with the feed roller being driven in any convenient manner and the regulation of
the feed effected solely by the pressing roller in conjunction with the piano feed.
Again, although we have shown and described the laying board it is not
essential for the purposes of our invention and it may be used or not, as preferred.
In the first of the alternative arrangements illustrated by Fig. 3, the end of the
lover is shown connected by a rod made in two parts to facilitate adjustment
to one end of a lever u which is fulcrumed on a shaft von which is fixed a
trough or dish plate we set adjustably at a convenient distance from the delivery
roller and above the feed lattice i.
When an excess of fibre passes under the roller h the trough w and shaft
are moved and by the levers u and connections t actuate the weighted levers sand
so move the pressing roller and the inclined needle lattice c nearer to the spiked
evening roller d and thus diminish the quantity of fibre passing over the top of the
inclined needle lattice c, the reverse movement taking place and an increased feed
being allowed to pass over the top of the lattice c when too little fibre passes
under the roller h.
In the second of the alternative arrangements illustrated by Fig. 3, the trough w
is dispensed with, and instead a roller a is mounted in bearings in a pair of
arms y fixed on the shaft the action being identical with that just previously
described.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
In the hopper feeders of opening and preparing machines-
1. The combination with the spiked evening roller or its equivalent on the outside
of the inclined needle lattice, of a movable presser roller or equivalent appliance
placed inside said lattice and connected to the piano feed regulator or equivalent feed
delivery regulator whereby its position and that of the needle lattice relatively to
the evening roller are controlled and the amount of fibre passing over the top of
5 the needle lattice is regulated.
2. The combination with the inclined needle lattice and the spiked evening roller
either with or without the laying board, of the movable weighted presser roller or
equivalent appliance placed inside said needle lattice and actuated by connections from
the piano feed regulator substantially as and for the purposes herein described with
O reference to Figures 1 and 2.
3. The combination with the inclined needle lattice and the spiked evening roller
either with or without the laying board, of the inovable weighted presser roller or
equivalent appliance placed inside said needle lattice and actuated by connections
from a pivoted trough or roller acting in conjunction with the delivery roller
5 above the feed lattice, substantially as and for the purposes herein described with
reference to Figure 3.

page_text: 4. The several combinations and arrangements of parts embodying our
'improvements substantially in the manner and for the purposes herein described
and as illustrated by the accompanying drawings..
