page_text: LETTERS PATENT to William Fox and Joseph Hall, both of Leeds, in the
County of York, for an Invention of "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR PREPARING AND FEEDING FIBROUS SUBSTANCES ON TO
SCRIBBLING AND CARDING MACHINES."
PROVISIONAL SPECIFICATION left by the said William Fox and Joseph
Hall at the Office of the Commissioners of Patents on the 31st December
1880.
WILLIAM Fox and JOSEPH HALL, both of Leeds, in the County of York.
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PREPARING AND FEEDING
FIBROUS SUBSTANCES ONTO SCRIBBLING AND CARDING MACHINES."
Our Invention relates to preparing and feeding apparatus for supplying wool
and other fibrous substances to scribbling and carding machines, dispensing with
the process of weighing the material in small quantities, and depositing the same
onto a "server or lattice sheet."
It is found in practice that the old system deposits the material on the " server
or lattice sheet" in unequal or irregular quantities; this is obviated by our improve-
ments, and is as bereafter described.
We construct a box or casing provided with a bottom, capable of being raised
automatically by means of a suitable rack and pinion, screw arrangement, or other
convenient means, the required motion being imparted from some suitable moving
part of the machine.
The material to be operated upon is placed within the hereinbefore mentioned
box or casing, and on the loose bottom being caused to move upwards the material
therein is also moved upwards. In order to relieve the box or casing of the
material as it is moved upwards we employ a traversing rake or spiked rollers at
the top thereof, and as the material is constantly moved upwards the prongs of the
rake drag off the material at the top and deposit it into a receiver applied in a
suitable position thereto. The upward movement of the false bottom of the box

page_text: may be effected by a rotating scroll shaft, whereby such upward movement may
be varied to suit the changes of density of the material in the box, or suitable
change wheels may be employed to regulate such upward movement. In order to
further assist in the upward movement of the false bottom, and to prevent any
backlash or receding thereof, we employ weights in combination with the herein-
before mentioned means.
Either one or both sides of the box or casing may be made adjustable, so that
their distances apart may be varied to suit the unevenness of the material contained
therein.
"
The receiver into which the material is deposited by the travelling rake or
spiked roller is provided with a travelling sheet, having pins or card filletting on
its surface, or card filletting alone without the sheet, or what is known as a
"licker in."
The material in the receiver by any of these arrangements is carried upwards,
and afterwards stripped therefrom by ordinary means and deposited in the carding
machine.
Our Invention further consists in an appliance for beating off the surplus or
superabundant material as it is brought up by the travelling sheet, card filletting,
or "licker in."
This is effected by a radial arm or rotating cylinder, that part thereof which
comes in contact with the material being provided with spikes, pins, or other like
appliances to suit the quality of the material.

"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PREPARING AND FEEDING
FIBROUS SUBSTANCES ONTO SCRIBBLING AND CARDING MACHINES."
Our Invention relates to preparing and feeding apparatus for supplying wool
and other fibrous substances to scribbling and carding machines, dispensing with
the process of weighing the material in small quantities, and depositing the same
onto a "server or lattice sheet."
It is found in practice that the old system deposits the material on the " server
or lattice sheet in unequal or irregular quantities; this is obviated by our
improvements, and is as hereafter described.
We construct a box or casing provided with a bottom capable of being raised
automatically by means of a suitable rack and pinion, screw arrangement, or other
convenient means, the required motion being imparted from some suitable moving
part of the machine.
The material to be operated upon is placed within the herein before mentioned
box or casing, and on the loose bottom being caused to move upwards the material
therein is also moved upwards. In order to relieve the box or casing of the
material as it is moved upwards we employ a traversing rake or spiked roller at
the top thereof, and as the material is constantly moved upwards the prongs of the
rake drag off the material at the top and deposit it into a receiver applied in a
suitable position thereto. The upward movement of the false bottom of the box
may be effected by a rotating scroll shaft, whereby such upward movement may be
varied to suit the changes of density of the material in the box, or suitable change
wheels may be employed to regulate such upward movement. In order to further
assist in the upward movement of the false bottom, and to prevent any backlash
or receding thereof, we employ weights in combination with the herein before
mentioned means.
Either one or both sides of the box or casing may be made adjustable, so
that their distances apart may be varied to suit the unevenness of the material
contained therein.
The receiver into which the material is deposited by the travelling rake or
spiked roller is provided with a travelling sheet having pins or cards filleting on
its surface, or card filleting alone without the sheet, or what is known as a
"licker in."
The material in the receiver by any of these arrangements is carried upwards
and afterwards stripped therefrom by ordinary means and deposited in the carding
machine.
Our Invention further consists in an appliance for beating off the surplus or
superabundant material as it is brought up by the travelling sheet, card filleting,
or "licker in."
This is effected by a radial arm or rotating cylinder, that part thereof which
comes in contact with the material being provided with spikes, pins, or other like
appliances, to suit the quality of the material.
And in order that our Invention may be more completely understood, reference
is given to the accompanying Drawings, and to the letters and marks thereon.

page_text: We construct a box or casing a, provided with a loose or false bottom 6 capable
of being raised and lowered through the medium of cords or chains or other
equivalent means. This motion is transmitted from the first doffer shaft by suitable
gearing through shaft c, worm d, worm wheel e, spur wheels c', and rope pulley ƒ,
on which is placed the cord or chain b¹.
.
h, h, are rakes; these are carried on pitch chains i mounted on the pulleys ;;
a rotary motion is imparted to the chain pulleys j through pulley j' from some
convenient moving part of the machine. By the rotary motion imparted to the
chain pulleys the pitch chain traverse the rakesh over the top of the box or casing,
and as the loose or false bottom b is drawn upwards the rakesh take off the
material with which the box or casing a is filled and deposit it into a second
receptacle ; out of this it is drawn up by a traversing toothed sheet 7, or when
preferred by fillet cards or spiked roller.
A beater off m is caused to revolve at a rapid rate; this has the effect of beating
back any clotted or large material into the second box or receptacle k, and continues
to do so until such material is reduced to smaller dimension previous to its entering
the scribbling machine. When the material has been reduced to smaller particles
the beater off m allows it to pass forward to be taken up by the stripping roller,
and thence onto the "licker in "and brest.
By the above arrangements a regular and evenly distributed supply of material
is constantly passing into the scribbling machine.
The beater off may when prefered be provided with pins, spikes, or laths at o.
To insure a regular quantity of material and an even pressure thereof upon the
traversing sheet we provide a slanting board p or its equivalent inside the second
receptacle, upon which the material rests after being delivered therein from the
first box or casing a; this slanting board is pivotted upon a shaft q. On the end
of this shaft q is carried an arm provided with an adjustable weight 8, which
can be so regulated as to balance the material on the slanting board p, thus acting
as a continous weighing apparatus. Should more material pass into the second
receptacle from the box or casing a than the machine requires, the over plus of
material overbalances the slanting board p, which falling back throws the feeding
apparatus out of gear by withdrawing the clutch t through the medium of the
levers u and v, which immediately stops the supply of material from the box a
until the surplus stock in the second receptacle k as been exhausted, when the
slanting board immediately returns to its proper position, throwing the clutch t
into gear and resuming the feeding operation.
In the herein before mentioned machine we may dispense with the ordinary
server sheet.
In order to suit the various kinds of material to be worked upon we provide
several modifications in the arrangements of various parts of the machine.
When it is preferred to retain the ordinary server sheet the material may be
taken from the toothed sheet or spiked roller, and deposited upon the server
sheet, or if evenness is not the essential point required we may take the material
direct from the first box a, and dispense with the toothed sheet / or spiked roller,
and relieve the box a of the material by a spiked cylinder or toothed apron, which
in either case will be stripped by a stripping roller on the server sheet.
A further modification consists in applying over the large box a a spiked roller 1,
which we cause to travel or to rotate at a great speed, the spikes of which when
set in motion would pass between other teeth or spikes provided in a stationary
.bar 2. Above this spiked roller and stationary bar 2 is applied a hopper 3, into
which the material is thrown, and then passed into the box a by the action of the
spiked roller 1 and the spiked bar 2. The material as it passes from the hopper 3 is
opened out and distributed into the box a evenly.
In order to insure evenness in the density of material in the large box a we
hinge the loose or false bottom at 4, Fig. 3, and fit castors on the outer edge to
ride against the side of the box a.
When the loose bottom 6 is at the bottom of the box it would be, as shown at 5,

page_text: Fig. 3, but would be straight, as shewn at 6, on arriving at the top of box a; this
arrangement of loose bottom compensates for the density of some material which
may become greater at the bottom than at the top.
The sides 7 and 8 of the box a are fitted so as to be moveable, and capable of
being swung from and to the false bottom b to regulate the density of the
material.
Motion is given to the various parts from the carding or scribbling machine.
Vertical travelling antifrictional sheet or sheets can be employed in combination
with the false bottom b.
Having now described the nature of our said Invention what we claim is,-
First. The means or apparatus employed for feeding scribbling machines,
dispensing thereby with the process of weighing, substantially as herein set
forth.
Second. The arrangement and application of false or loose bottom b, and parts
connected therewith, for giving and arresting the motion of the same, substantially
as and for purposes herein set forth.
Third. The arrangement, construction, and application of the sides of the box,
these being so arranged that they can be moved to and from the loose or false
bottom to suit the density of the material, substantially as herein set forth.
Fourth. The arrangement and application of travelling rakes /, substantially as
and for purposes herein set forth.
Fifth. The arrangement and application of beater off m, substantially as and for
purposes herein set forth.
In witness whereof, we, the said William Fox and Joseph Hall, have hereunto
set our hands and seals, this Twenty ninth day of June, in the year of
our Lord One thousand eight hundred and eighty one.
