page_text: plants or leaves being treated. A feed roller D works in connection with a second
or upper feed roller D', rotary motion being given to these feed rollers through a
sprocket wheel and chain u, or by carrier gear (not shown) from the crushing
roller J, as hereafter described.
As the fibrous plants, or portions of them, are being carried forward by the
travelling apron C, the upper feed roller D' is raised and disengaged from the
lower feed roller D, causing the roller D and the belt to cease movement at
intervals, and a stop-board or shutter F is provided to be brought down upon a
plate G, which latter constitutes a fixed portion of the feeding device, in line with
the carrying surfaces of the belt C. This may be done by fitting the bearings of
the top roller D¹ and the stop board F to work at their ends in guides or
grooves D2, D3, respectively and connecting them by a rocking beam or lever H,
to which a lifting motion is given by a foot lever or treadle I, to raise the roller D'
and lower the stop board F, simultaneously as required.
The bearing or roller D' is connected by a link with lever H and the sprocket
chain u connecting pulley on roller D₁ with pulley on roller J is sufficiently
slack to permit the roller D' to rise the short distance required in a vertical
plane.
The object of thus raising the roller D₁ and lowering the stop board or
shutter F, is to close down in front of the foremost leaves or portions of the plants
for the purpose of arresting them in their feed until their ends are all even or in
line. This operation of evening the ends of the plants can be conveniently
performed by hand. Upon removing foot pressure from the treadle I, the roller D₁
drops into its normal position again, imparting motion to the lower feed roller D
and the apron C, the stop board F rising at the same time to its normal position,
when the feed passage will be opened and the leaves will be delivered over the
feed plate or table G and between a pair of crushing rollers J and J. As the
forward ends of the leaves or portions of the plants under treatment pass from
between these crushing rollers J and J', they come in contact with a concave
deflector or deflecting plate K, which directs the leaves in a downward course
between the crushing roller J' and another crushing and gripping roller J' in the
same horizontal plane.
The material to be stripped then passes between the two rotary beater or
scraper drums M and M. These drums are preferably composed of a body
having integral paddle or breaking blades b, with rubber bearing strips s dove-
tailed in the depressed surfaces between these breaking blades acting as yielding
cushions, whereby the outer end of rigid paddle or blades b are made to beat and
scrape the fibre as it passes between the beater or scrapers and the flexible
cushions of the drums M and M. These rotary beater or scraper drums M and M¹
may be suitably driven first in one direction and then in the other, and are geared
to rotate simultaneously and uniformly through the gear wheels P. An enlarged
hub or drum P2 having preferably a grooved periphery is made to project from
one or more of the gear wheels in position to be operated upon by a brake lever P³
in proximity thereto. This lever P³ is pivoted at and is connected at points on
opposite ends of its pivotal point with flexible brake straps which latter are
secured at their outer ends rest within the grooves in the peripheries of the
drums P2. The object of the forward and reverse motion is to beat and scrape off
the covering from both sides of the plant or leaves in one passage through the
machine, the beaters or scrapers B repeatedly striking the leaves or material
treated at short distances apart transversely to their downward travel, while the
flexible cushions s hold up the leaves or material to the beaters or scrapers b, and
are designed to prevent the fibre from being cut or injured as it would be if the
beaters forced it against a rigid surface. The leaves then pass between a pair of
gripping rollers N and N', preferably rubber faced which hold the fibre and carry
it downward while the beater or scraper drums M and M' are operated in a reverse
direction for the purpose of scraping the end of the leaf which has not yet passed
between the drums and then scraped before the motion of the latter is reversed.

page_text: From the grip rollers N and N₁ the fibrous material is delivered between a pair
of drums P and P¹ (see Fig. 6), each of which is constructed similar to the
beater and scraper drums M and M¹ except that on their peripheries brushes d
alternate with the wipers e and there is preferably a corrugated or concave surface
between each brush and wiper.
The brushes d may be made of any suitable material, and the wipers e be com-
posed of flat strips of leather, rubber, or other flexible material, set edgewise on
or along the drums P and P¹.
The brushing and wiping drums P and P¹ serve to brush and wipe from the fibre
any adhering pulp or substance. Said drums P and P¹ rotate in concert in the
same manner as the drums of the beater and scraper M and M', as, for instance,
by gearing P3 and P³ and made to revolve and reverse alternately, as hereafter
described.
Lower rollers Q Q' one or both of which are provided with flexible facings
having taken hold of the fibre or material, and just before the fibre is released
from the grip rollers N and N¹, the brush and wiping drums P and P' are reversed,
which keeps the fibre straightened or held perpendicularly while being brushed or
wiped, and allows it to be carried through the grip rollers Q and Q¹in an untangled
mass conveying it to the delivery apron S.
S is an endless belt passed around the roller Q1 whereby it is driven and the
outer tension roller T and serves to deliver the fibre away from the machine. U is
another endless belt arranged to pass around the flexible roller Q small pulley h¹
and h, and outer tersion pulley f', and serves to prevent the fibre from wrapping
around the roller Q and at the same time to drive the shive belt V.
Š
The belt V is passed over rollers h and h¹ and is driven in the direction of the
arrow by the contact therewith of belt U which before passing around roller Q
passes under roller and then over roller. The object of the belt V is to carry
away the greater part of the shive. Some little will pass downwardly onto apron
but by locating the rollers hh' near roller Q, the belt V is brought under the
wiping drum so that the greater portion of shive which is beaten, brushed or scraped
off while the fibre is held between rollers QQ, falls onto apron V and is carried
away.
Z is the driving pulley for the feeding crushing and delivering mechanism and it
is fast upon a shaft a, which extends from the right to the left side of the main
frame A. Upon its left end and outside of the main frame is fixed a pinion a',
which is made to engage or mesh with a gear wheel a³, fixed upon a counter
shaft a, and upon which is fixed another smaller pinion a, which engages or
meshes with another larger gear wheel as, fixed upon another counter shaft a³, and
which also has another pinion a' smaller than itself which meshes with and drives
a still larger gear wheel b on the front intermediate grip roller shaft ad. Upon this
same grip roller shaft a" is a small pinion a³, which is also fixed thereto and engages
with both the upper carrier gear wheel n and lower carrier gear wheel n¹. These
carrier gear wheels n and are hung upon independent studs i and i, and the
upper carrier gear wheel n carries the motion given it by the pinion as to the gears
on the rollers JJ' and J2 and the sprocket wheel von roller J and to wheel von
The lower
roller D' through the sprocket chain u thus driving the feed roller D'.
carrier gear wheel n' receives its motion from the same pinion a³, and imparts it
to the gear wheel g on the grip roller Q, which through the gear wheel g
drives the roller Q₁and apron belts S, V and U. The top pulley W is provided
with two faces, one to receive the driving belt o and the other having grooves
to give an extended frictional surface. This pulley W revolves upon an
excentric shaft l, which is made to oscillate by means of the lever y secured
thereto and vibrated through rod y' and pedal I¹ whereby said pulley W is
thrown from contact with the flat pulley R, where the tension of the driving
belt o normally keeps it, into contact with the pulley R', which causes a reverse
motion to be given to drum M M by pressing the foot down upon the
pedal I. The moment the foot is raised, the tension of the driving belt o

page_text: brings the friction pulley W to its former position, and keeps it there until
required for reversing the drums M and M' again. The pulleys R and R' are
provided with V grooves to suit the pulley W, as desired, their position being
upon the outside ends of the two drum shafts M and M', and for the purpose
already described. The lower pulley W₁ is arranged upon the eccentric shaft / in
the same manner as pulley W upon the shaft and gives motion to the brush and
wiper drums PP¹ through the spur gearing P2 and P3 and friction pulleys P
and P. The lower shaft or pulley Wis oscillated by the pedal I lever I³ and
link 1. Instead however of grooving the faces of the pulleys as described they
may be plain.
Slight differences exist in Figs. 8, 9, 10, 11, 12, 13, 14 and 15 from the con-
struction set forth as will now be described.
The material to be stripped after being fed into the machine and deflected down-
ward passes through a brass trumpet K2 where it is operated upon by the double
horizontally reciprocating breakers M, M. The breakers each consist of a cross
head m to which are secured elongated slotted plates m³, m³, which interlock with
each other and have a slight clearance m² between them. Plate M³ constitutes a
cover over the breakers and the plates m' serve as tracks on which the ends of the
breakers ride, the tracks being supported suitably by the main frame of the
machine. These reciprocating breakers are actuated by eccentrics M², mounted on
driving shaft a. By projecting in precisely opposite directions, the eccentrics
reciprocate these breakers simultaneously in opposite directions so that by one
throw the position of the plates is such that the material is at the other side of the
slots and at the next throw at the inner sides and so on but at each time a throw is
made the continuous passage through being opened for an instant allows a little
more material to pass. Thus the fibre is held in a rapidly vibrating zig-zag never
being broken but having the trash broken from it during its passage. The object
of the wider slots s² is to allow any pulp to pass without clogging.
It sometimes occurs that the throw of the breakers is too much or too little and
to regulate this I have devised the following mechanism. The eccentrics instead
of having a fixed position on the shaft are each provided with an elongated slot n³
through the center, made of suitable size to receive an adjustable shaft box and
preferably having a scale n on its edge so that the lateral projection of the
eccentric upon the drive shaft may be changed or varied by changing its center on
the shaft from one extreme of eccentricity to not so great an extreme. The
eccentrics may be held in such position by set screws or by means of a strap c³
having a hole to receive the shaft and screws c³ whereby the strap is secured to the
eccentric. Thus the throw of the breakers may be made greater or less avoiding
the use of breakers with broader or narrower slots which would otherwise be
necessary in order to accomplish the same result.
This gearing being a trifle varied requires description:
Z is a pulley upon one end of shaft a, which extends from the right to the left
side of the main frame A where it is provided with a balancing wheel ³. A
similar shaft Z traverses the machine from right to left and is provided on one end
with a pulley Z2 in close proximity to pulley Z over which drive belt o passes and
on the other end with pinion Z13 meshing with a large gear wheel Z* on the end of
the shaft J. This same shaft also carries a small pinion a' immediately back of
gear wheel which meshes with and drives gear wheel a³ on the shaft which
carries the crushing roller J. Clutch mechanism is preferably connected with
pulley whereby the machine can be quickly stopped or started at a moments
notice and when the parts are removed. This same shaft also carries a small
pinion as immediately back of gear wheel a³ which meshes with and drives wheel a
on the shaft which carries back crushing roller J2 and also with a gear wheel above
it for driving roller J and with a gear wheel a, the latter imparting motion to the
gear wheel g on the lower grip roller Q which through the gear wheel g drives
the elastic roller Q and bolts S, V & U.
The pulley W is provided with two faces, one to receive the driving belt o, and.

page_text: the other made either with a plain or straight face, covered with leather to give a
frictional surface, or, if desired it may have V grooves instead to give a more
extended frictional surface. This pulley W revolves upon an eccentric shaft 1,
which is made to oscillate by means of the lever Y secured thereto whereby the
driving surface of pulley W is thrown from contact with the flat pulley R, where
the tension of the driving belt o normally keeps it, into contact with the flat
pulley R', which causes a reverse motion to be given to the drum P, P¹, by
pressing down upon the lever Y. The moment the pressure is removed, the
tension of the driving belt o brings the friction pulley W to its former position,
and keeps it there until required for reversing the drums P and P₁ again. The
pulleys F and R₁ have faces to suit those of the pulley W, as desired, their
position being upon the outside ends of the two drum shafts P and P¹ and for the
purpose already described.
In the compressor shown in Figs. 16 and 17 A is a frame in which two sets of
rollers are journalled the lower by preference in fixed boxes and the upper in
adjustable boxes a, which move in slots spring cushions being located back of
them to allow them to yield as the leaves pass, and set screws being provided to
regulate the tension of the cushions.
BB represent the rollers at the forward end of the series. These rollers
are corrugated and near to each other. C, C', represent the next pair. DD₁ the
next and E, E the next and so on indefinitely until as many as are needed are
employed, they varying in number usually to correspond with the length of the
leaves that the machine is designed to operate upon, and the distance between the
two series increasing toward one end. The rollers C, C, D, D' and E, E' are
all plain rollers and may be of wood but preferably are sleeved or faced with
brass or other non-corrosive material.
The spindles carrying the rollers are each provided with gear wheels d and
between these pinions e, e¹, are meshed so that the motion of all the rollers in each
series is the same.
Filling the spaces between the lower rollers are the perforated plates F which
allow the juice as it is squeezed out of the leaves to drop into a receptacle G.
Suitable plates H are preferably located in corresponding position above the
perforated plates.
On the shaft carrying the corrugated roller B, a gear wheel of is secured. A
pinion g on the main drive shaft meshes with this gear wheelf and the shaft is driven
by a bolt through the pulley J. After leaving the rollers the material is carried
off on conveyor belt K.
At the opposite end of the machine the feed belt L is mounted on the rollers M
the inner one of which is provided with a gear wheel p', which latter is adapted to
be engaged by the gear wheel p on roller N, when the latter is in its lowered or
operative position. The roller N is located over its mating roller M, and is
mounted in sliding boxes m, seated in the elongated bearings n. These boxes m
are connected to the pivoted levers O, (one on each side) by links o, and the levers
are connected to the movable stop board O' by suitable links. The stop board and
roller N together with the connecting mechanism are so arranged that when one is
depressed the other is elevated and hence when the roller N is lowered so that the
gear wheel p thereon meshes with the wheel p' on its mating roller M, the stop
board Ois elevated and hence permits of the passage of the material fed through
by the feed rollers. When the stop board is in a depressed position the roller N is
elevated, and as the roller N and feed belt L are operated by roller E, through
chain it follows; that when roller N is elevated the feed belt is stopped. When
the parts are in this position the material to be operated upon can be evened
up against the stop board:
In Figs. 18, 19, 20 and 21 A represents the frame of the machine and A¹ is a
table projecting from the front end of the frame. A pair of stripping cylinders 1, 1,
are journalled in the rear end of the frame. The teeth 2, 2, on these cylinders are
preferably shaped substantially as shown having one straight edge and one rounded

page_text: edge and so arranged that the teeth on the two cylinders will intermesh with one
another and remove the leaves and at the same time have sufficient clearance
between them for the passage of the stalks undisturbed by the teeth.
An endless belt or apron 3 is carried on rollers 4 and 5 journalled in the table A¹.
A small roller 6 supports this apron at the middle and an adjusting devicè 7 is
provided for shifting the roller 4, whereby the tension of the apron is regulated.
The stalks to be stripped of their leaves are placed on this belt or apron and by its
forward motion carried onto the feed plate 8 and thence between the stripping
cylinders 1, 1. To facilitate the feed of the stalks to the cylinders, the upper feed
roller 9 is revolubly supported just above roller 5 and is adapted to coact with the
latter to force the stalks forward or backward.
This roller 9 is made yielding by means of a rubber or leather covering and not
only does it grip the stalks but also by its contact with the roller 5 it is rotated and
whatever passes between it and the roller 5 is securely held and forced forward or
backward as the case may be.
The shaft 10 on which the lower cylinder 1 is mounted, is provided with a driving
pulley 10 at one end through which motion is given to the entire machine and gear
wheel 10 through which motion is given to wheel 11ª and at its opposite end this
shaft is furnished with a worm wheel 11. The shaft 12 on the corresponding end
of the machine is journalled in the bearings 13, 13, and has the worm gear wheel 14
affixed thereon and in mesh with the worm wheel 11 through which motion is
imparted to the shaft. The shaft upon which the roller 5 is mounted is provided
with a bevel gear wheel 15 and the shaft 12 has a pair of bevel pinions 16 and 17
slidingly keyed thereon whereby they are alternately thrown in and out of mesh
with the wheel 15 accordingly as the endless apron is to be driven forward to feed
the stalks or reversed to withdraw them. These pinions are each furnished with a
grooved collar 18, 18, and the yoke 19 secured to the rocking shaft 20 engages these
collars and keeps them always at the required distance apart so that the two pinions
are simultaneously operated by this yoke and slid in or out of engagement with the
gear wheel 15. The rocking shaft is supported in bearings 21, 21 and has a
reversing lever 22 on its opposite end by means of which the pinions are shifted
to reverse the motion of the apron and this lever is held in position by the toothed
segment 23.
The machine is set in motion by the belt 24 and the stripping cylinders and feed
rollers are rotated until the stalks have passed between the cylinders and nearly
through the feed rollers.
Then the lever 22 is reversed through the pinion 16 which before has driven the
gear wheel 15 out of engagement with the latter and the pinion 17 into engage-
ment. This gives the apron opposite motion and withdraws the stalks from the
machine.
In Figs. 22, 22, 23, 24, 25, 26 and 27 A represents the shell of the digester.
This is of cylindrical form and supported on the legs a, a. On the rear end of the
shell the back C is rigidly secured and on the opposite end the head B is removably
secured. The means of attachment between the shell and this head is as follows:
A flange D is riveted or otherwise affixed to the shell so that its outer edge d, which
is conveniently thickened, projects some distance beyond the end of the shell. The
flange is provided on this thickened portion with an annular recess or female gland H
and on its inner face with wedge shaped lugs or projections E varying in number
according to the size of the digester and the amount of the steam pressure exerted
on the inner walls. The removable head B is furnished with an annular rod or
male gland I adapted to enter the female gland H and press against the rubber or
other packing therein to form a steam tight joint. The head is also furnished with
hook shaped lugs G corresponding in number to the lugs E and adapted to enter
the spaces between the latter when the head is placed on the digester and be turned
laterally to engage the lugs E. The faces E' and G' are inclined in opposite
directions so that as the head is turned in the direction indicated by the arrow after
first being pushed in as far as possible the parts are drawn tightly together, the

page_text: male gland sinking deeply into the female gland and impinging tightly against the
packing in the latter so that a perfectly steam tight joint is formed. This turning
of the head is produced by means of a screw J which is supported in supports or
bearings L, L, and which engages a nut W fitted in a recess in the rim of the head.
The screw is turned by means of a wheel or handle K on its outer end and by the
cam action in the nut the head is turned. To open the digester the screw is turned
in the opposite direction until the lugs G are opposite the openings between the
lugs E. The head is then rolled or shifted to one side.
Inside or outside of the digester and preferably at or near the rear end, the
filter is located. This is formed by means of a partition F. A perforated plate Q
constitutes the bottom of the filter and the filter is filled with suitable material for
filtering the dissolvent as it passes through during the process of degumming the
fibres.
U represents a carriage consisting of the frame P and the bottom V and mounted
on truck R which runs in upon the track R'. The carriage is lined with suitable
netting or other material and the fibres are placed therein.
M is a pipe through which the dissolvent circulates in its passage into the
digester and N is the pipe out of which the dissolvent flows after passing through
the filter. The dissolvent is forced by means of a circulating pump (not shown)
from the pipe N into the pipe M and upon passing out of the latter, it passes through
the fibres in the carriage.
The take-up pipe O leads from a tank or reservoir (not shown) above the filter
into the pipe N at which point the supply is controlled by a valve O', and from this
the pipe N is supplied.
Coils of steam pipes X beneath the truck supply the heat required in the process
of removing the gum. A plate S at one end of the digester fits around the carriage
and prevents the dissolvent from passing around outside, insuring its passage
through the fibres.
In operating my digester, the head is removed and the carriage is filled with
fibres and run into the digester. The hand wheel or handle is then turned until the
head is secured fast in place tight enough to prevent the escape of any steam.
After having prepared the dissolvent it is placed in the tank above the digester
from which it is fed as fast as desired. Upon opening the valve O¹ in pipe Othe
dissolvent flows into the digester. When the proper quantity is run in, the valve is
closed and the steam is turned on, causing the dissolvent to boil. After the boiling
has continued a sufficient length of time, the steam is turned off and the contents of
the digester are allowed to stand for a while. The steam valve and valve in pipe O
are then opened again. The result is that the liquid ascends to the tank above the
digester, the steam pressure being greater than the weight of the liquid in the
take-up pipe. When all the liquid is blown out of the digester the head is taken
off and the operation is completed. If it is required to wash the fibre it can be done
while in the digester by the attachment of a water valve and pipe for this purpose.
In Figs. 28, 29, 30 and 31 A represents the body of the drier. The drying
chamber 1 comprises the central portion of the body and the partition 2, 2,
at either side separate from it the two narrow cooling and condensing
compartments 3, 3.
Above the chamber 1 and the compartments 3, 3, a dome is located and this too
is divided into communicating compartments 4, 5 and 6 in which the air is put in
circulation. The compartments 4 and 5, communicate at their lower ends with the
cooling and condensing chambers 3, 3, at the sides and the chamber 6 with the
drying chamber 1. The fan or blower 7 is so arranged in the dome that it
continually forces a current of air downward into the drying chamber 1 and by the
suction created from its rotation induces a steady continuous current through the
drier by withdrawing air at the same time from the cooling compartments.
The fan or blower is mounted on a shaft 8 and the latter is driven by pulley 9.
While this has been found a convenient location for the blower, it is by no means
confined to this position as the circulation might be maintained just as well if the

page_text: blower were further away. It is simply placed above the drying chamber to be
nearer at hand and also to economize space.
Steam pipes 10, 10, 10 extend across the upper end of the drying chamber so
that the air upon entering the drying chamber is at once heated, and the cooling
compartments 3, 3, at the sides are supplied with cold water pipes into contact with
and around which the heated air is deflected and during its passage between them
cooled and the moisture from it condensed so that it is left dry each time when it
returns to the fan or blower. Drip troughs 11, 11, are placed beneath these cold
water pipes to catch the water dripping from the pipes from condensation and siphon
pipes 12, 12, conduct this water off from the trays.
The trays 13, 13, 13, which contain the fibre or other material to be dried are
carried into the drying chamber 1 by an endless chain 14, and on tracks 20, 20.
These trays have open work or perforated bottoms to allow a free circulation of air
through them and the bottoms are preferably of rattan or similar structure. The
chain travels on sprocket wheels 15, 15, and these are keyed or otherwise secured to
the shafts 16, 16, which are turned by means of cranks or similar devices 17, 17.
Certain links of the chain are provided with outwardly projecting lugs or pro-
jections 18, 18, which engage with the drawers in order to carry them in and out of
the drying chamber as the cranks are rotated and the chain moved.
A shelf 19 is stationed at either end of the drier to hold at least one tray so that
they may be fed in from one end, one at a time, and removed from the opposite end
one at a time.
It is seen that the air from the inside is kept in continual circulation and the
introduction of damp air from the outside is avoided.
By way of further explanation it may be mentioned in conclusion that the air
may be variously circulated but it is always heated before passing through the trays
and again cooled and dried before reaching the blower or fan and it is evident
that slight changes might be resorted to without departing from the spirit and
scope of my invention, and hence I do not wish to limit myself to the particular
construction herein set forth, but,
