Improvements in Machines for Hulling or Husking Grains, Seeds,
or the like.
I, WILLIAM VAN VLECK LIDGERWOOD, of 96 Liberty Street, New York,
United States of America, Manufacturer do hereby declare the nature of this
invention to be as follows:-
My invention relates to improvements in machines for hulling or husking grains,
seeds, or the like and is chiefly designed for removing the outer dried skin or
envelope from coffee beans.
The principal object of my said invention is to improve and simplify the means
employed in hulling or husking machines, for securing husking plates of any
suitable kind in position upon the cylinder, and for enabling them to be readily
adjusted from the exterior of the machine, so that the said machines may be used
and maintained in order by unskilled and careless attendants in places, for instance,
where skilled labour is unobtainable. Other objects of my said invention will be
hereinafter disclosed.
According to my said invention I secure upon the outside of the husking
cylinder and parallel with its axis, suitable plates hereinafter termed base plates,
cach provided with a raised edge or bend, or being otherwise formed so that one
edge of each husking plate, which also is bent or otherwise made of hooked form,
will hook under the raised or "hinge" edge of the base plate, about which the said
husking plate turns as about a hinge.
Between each husking plate and the base plate or the cylinder a buffer of india-
rubber or a spring is interposed, and a bolt is passed through the husking plate
and the buffer or spring, or through the buffer or spring alone, and screwed into
the base plate or the cylinder to keep the buffer or spring in place, and to be
employed in certain cases for a purpose hereinafter described. The said buffer or
spring is provided in order to permit the husking plate to turn through a small
angle about the raised or "hinge edge" of the base plate, towards the cylinder,
when caused to do so by the resistance of the material which is operated upon, and
to cause it to move in the opposite direction when the said resistance is removed;
the head of the bolt, when the bolt is passed through the plate acts to limit the
movement in the said opposite direction.
In suitable bearings upon the outside of the said cylinder, I provide a series of
shafts, each shaft being parallel with the axis of the cylinder, and in guides or
bearings on the cylinder are bars which also are parallel with the axis of the
cylinder, and adapted to move endwise as hereinafter described; the said bars are
provided with a series of inclined surfaces, inclined slots, or the like, or with
anti-friction rollers whose centres are on a line inclined to the direction of movement
of the bar.
Upon each shaft a two-armed lever or two-armed levers are arranged, one arm
of each lever bearing upon one of the inclined surfaces or slots of one of the
aforesaid bars, or upon anti-friction rollers carried thereby, and the other arm
bearing upon one of the husking plates at a point intermediate between its hooked
edge and its free edge, so that by moving the said bars endwise in their guides or
bearings, the inclines, rollers or slots thereof will operate the aforesaid two-armed
levers to move the husking plates towards, or to allow them to move away from,
the cylinder; the said levers limit the outward movement of the husking plates
about their fulcra at the raised or hinge edges of the base plates.
Moreover the two-armed levers are preferably formed so that when they are in

page_text: position on their shafts, suitable projections upon the said levers prevent the hooked
edges of the husking plates from becoming accidentally disengaged from the raised
or hinge edges of the base plates. To enable the said husking plates to be
disengaged from the base plate when necessary, the sliding bar formed in such
a manner that if moved endwise sufficiently far, the aforesaid inclines rollers, or
slots thereon will disengage the ends of the said levers, which may then be turned
upon their shafts through a sufficient angle to move the aforesaid projections clear
of the hooked portions of the husking plates, which may then be readily disengaged
from the base plates; suitable notches or recesses are provided in the sliding bars
and in the cylinder and base plates, where necessary, to enable the said levers to be
turned as described. I consider the combination of the said two armed levers with
husking-plates hinged to the cylinder by any suitable means, to be a very important
feature of my invention; I may employ any suitable means to adjust the two-
armed levers.
As an alternative arrangement adapted to limit the movement of the husking
plates away from the periphery of the cylinder whilst permitting a certain amount
of movement of the husking plate within the said limit, stirrups or eyes are secured
to each husking plate, and a bell-crank lever is pivoted upon the periphery of the
cylinder opposite each said stirrup or eye. One arm of each bell crank lever
enters the said stirrup or eye and the other arm of each lever is connected to and
controlled by one of a series of bars arranged to move end wise in guides or bearings
upon the cylinder, so that by moving them the bell-crank levers act upon the
stirrups or eyes and draw the husking plate inward; the stirrups or eyes are
provided with openings of such length that the said plates may move further
inward independently of the bell-crank levers but their outward movement will be
limited thereby as aforesaid. As an alternative the bell crank levers may be
connected to the husking plates by chains or other flexible connections.
The means which effect the operation of the said end wise-moving bars for
operating either the two armed levers or the said bell-crank levers are arranged as
follows:-
Upon the central shaft or spindle of the husking cylinder a hub or sleeve is
provided, arranged to rotate with the cylinder, and to be moved upon the said shaft
or spindle in the line of the axis thereof by means of a rod which is passed axially
through the shaft or spindle, and is connected at its inner end to the said hub or
sleeve, and at its outer end is screw-threaded to receive a hand wheel, which bears
upon the end of the shaft or spindle or upon any other suitable bearing, and by
means of which the rod is moved end wise to adjust the hub or sleeve by giving it
the said endwise movement upon the shaft or spindle. Upon the said rod is
another hand wheel, or nut or other suitable device for the purpose of locking
the first-mentioned hand wheel in place when the hub or sleeve has been properly
adjusted.
The said hub or sleeve is provided with a series of radial arms which pass
through the wall of the cylinder and engage with the several sliding bars and move
them endwise when the hub or sleeve is operated in the manner hereinbefore
described. In order to keep dust out of the interior of the cylinder the said radial
arms, where they pass through the said wall, are provided with shutters or followers
of metal or other suitable material, which always effectually close the spaces around
the said arms by which, otherwise, dust might enter.
To prevent dust from getting between the said hub or sleeve and the surface of
the shaft or spindle upon which it slides, I secure flexible tubular dust-guards of
leather or other suitable material to each end of the hub or sleeve and to washers
secured upon the shaft or spindle; the said dust-guards encircle the shaft and keep
out the dust, while permitting the hub or sleeve to be moved freely thereon.
As a further alternative, where the husking plates are secured in place upon the
cylinder and their movement about the raised or hinge edge of the base plate is
controlled as described in my Specification of Letters Patent dated 27th May
A.D. 1884 No. 8300, I employ in combination therewith novel arrangements for

page_text: preventing the husking plates from becoming disengaged from the base plates by
the breaking of a bolt, which, as described in my said prior Specification, is passed.
through each husking plate at a point intermediate between its hooked edge and
its free edge, that is to say, I provide in suitable bearings upon the periphery of
the cylinder a series of spindles which are parallel with the axis of the cylinder
and are provided with cams, eccentrics, or other suitable projections, one spindle
being appropriated to each husking plate or to each series of husking plates and
one or more projections being appropriated to each husking plate. Each said
projection is so arranged that with its spindle in its normal position the projection
will prevent the husking plate from becoming disengaged from the base plate even..
if the aforesaid bolt should break. A suitable handle is provided upon each
spindle, whereby it may be turned to move the projections thereon out of engage-
ment with or out of proximity to the husking plates, to permit them to be removed
when desired. The said handles are preferably so arranged that while they and
the spindles are in a position in which the husking plates are not locked in place,
the husking chamber in which the cylinder is placed cannot be closed; this
arrangement, when the husking plates are not secured, prevents the machine from
being closed, by careless attendants. Instead of employing special shafts with the
said projections thereon, eccentrics, cams or other projections may be formed upon
the shafts on which the hereinbefore mentioned two-armed levers are placed, and
the said shafts may be turned by handles arranged as described while still serving
as bearings for the two armed levers.
As an alternative arrangement for limiting the movement of the husking plates
I connect them by suitably slotted connections or by flexible connections to plates
or battens arranged in or upon the periphery of the cylinder and I move the said
plates or battens inward or outward upon the cylinder by means of a series of rods
or bars connected to the said plates or battens and operated to move radially
outward in suitable guides or bearings in the cylinder by sleeves or hubs, which are
provided with wedges, cams or cam plates, or friction rollers and are moved in the
line of the axis of the cylinder and locked in proper position after adjustment by
means similar to those hereinbefore described with reference to the adjusting and
locking of the hub or sleeve controlling the sliding bars by which the bell-crank
and two-armed levers which limit the outward movement of the husking-plate are
adjusted.
Τ may provide at the inner end of each of the said rods or bars an anti-friction
roller and upon the said hub or sleeve I place plates having inclined slots adapted
to receive the said rollers and to move them radially in or out.
Instead of constructing the outer cylinder or husking chamber in the manner
which has hitherto been customary, that is to say, of staves arranged in such a
manner that several bolts must be withdrawn in order that access to the interior of
the cylinder may be obtained, I form one section or segment of the cylinder wall as
a door, with suitable hinges upon which it may turn. The edges of the said door
are bevelled in order to enable it to open readily, and so that it may, when closed,.,
make a tight joint.
:
:
Further, in order that the wire-cloth, or the like, which forms part of the wall of
the said outer cylinder, may be secured in place without such damage as now arises.
from the prevalent practice of nailing the said wire-cloth to the staves, I bolt or
otherwise secure the wire-cloth to suitable bars, or the like, before it is placed in
the husking machine and I form in other staves or standards placed as is customary
around the husking chamber, suitable recesses to receive the aforesaid bars, and in
the said bars and staves I form bolt holes, so that simply by placing the bars in place
in the recesses in the staves and passing suitable bolts through both, the said bars and
the wire cloth secured to them are retained in place in such a manner that they can
be readily removed from the machine and as readily replaced therein, without such
damage to the machine as has hitherto occurred from the repeated driving of nails
or spikes into the staves at different places; I preferably form the wire gauze and
the bars to which it is secured, in such a manner that when placed.in position in the

page_text: husking chamber as above described and without further fitting or manipulation,
the true cylindrical form of the interior of the said chamber is preserved.

Improvements in Machines for Hulling or Husking Grains, Seeds,
or the like.
I, WILLIAM VAN VLECK LIDGERWOOD, of 96 Liberty Street, New York,
United States of America, Manufacturer, 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 :-
My invention relates to improvements in machines for hulling or husking grains,
seeds, or the like, and is chiefly designed for removing the outer dried skin or
envelope from coffee beans.
The principal object of my said invention is to improve and simplify the means
employed, in hulling or husking machines, for securing husking plates of any
suitable kind in position upon the cylinder, and for enabling them to be readily
adjusted from the exterior of the machine, without the necessity for stopping the
working. Improved machines constructed according to my invention may be used
and maintained in order by unskilled and careless attendants, in places, for instance,
where skilled labour is unobtainable. Other objects of my said invention will be
hereinafter disclosed.
In order that my said invention may be clearly understood I will now proceed
to describe the same with reference to the accompanying drawings, wherein
Figure 1 is a longitudinal central section of an improved hulling machine con-
structed according to my invention,
Figure 2 is a sectional plan of the machine shown in Figure 1,

husking cylinder for a husking machine, and will be hereinafter particularly
described,
Figure 6 is a cross section on the line y y of Figure 5,
Figure 7 is a development of a portion of the cylinder illustrated in Figure 5,
and shows the arrangement of the husking plates thereon to "break joint" with
each other,
Figure 8 is a longitudinal central section of one end of another alternative
construction of inner cylinder,
Figure 9 is a transverse section of the same on the line z z of Figure 8,
Figure 10 is a longitudinal central section of one end of a further alternative
construction of inner cylinder,
Figure 11 is a transverse section of the same on the line of Figure 10,
Figure 12 is a perspective view of a detail of Figures 10 and 11, and
Figure 13 is a view of part of a husking cylinder in transverse section and will
be hereinafter particularly described.
Similar reference letters indicate corresponding parts throughout the drawings.
With reference first to Figures 1 to 4, A is a rotatable husking-cylinder
secured upon the shaft B which turns in bearings C, and is rotated by any
suitable means.
B' is a driving-shaft and B2 is a clutch by which the shafts 1
and B can be connected. D is a casing which encloses the cylinder A. The
said casing contains a tubular chamber E having walls E' of wire gauze or
other suitable perforated material. The lower portion D' of the casing D is

page_text: arranged as a receptacle for the dust which falls through the walls E from the
material treated.
D' is a hopper communicating by a channel D³ with the interior of the chamber E.
F is a wheel secured upon a rotatable spindle F and provided upon its periphery
with blades or pockets, so that when rotated it delivers material from the
hopper. D' into the said chamber E and at the same time partially crushes
the husk of same. G is a sprocket wheel upon the spindle F'. H is a
sprocket wheel upon the shaft B. A chain G¹ is passed round the said sprocket
wheels to gear them together so that the shaft B will effect the rotation of the
feed wheel F. E' is a channel by which the material treated passes, together
with the husks or hulls, out of the chamber E to a sieve box E wherein any
suitable means are provided for separating the said husks or hulls from the berry
or valuable portion of the material treated.
In bearings I upon the outside of the cylinder A, shafts J are secured.
KK are the husking plates, bent at opposite sides as shown at K₁ K². The
bent edge K of each husking-plate engages with and turns upon one or other of
the shafts J. The bent edge K² of each husking-plate is provided for a purpose
hereinafter set forth.
A series of battens L are arranged parallel to the axis of the cylinder and are
adapted to slide radially, that is to say in a direction at right angles to their length,
in slots therein. Metal plates L' are bolted to the sides of the said battens.
Between the extensions 1 of the said metal plates near the opposite ends thereof,
bars M are boited; the said bars project from between the extensions L of the
plates towards the shaft B and are furnished with flanges M' inclined to the said
shaft B.
NN are bosses adapted to slide upon and to rotate with, but not relatively to,
suitably-shaped portions B3 of the shaft B. The said bosses are provided with
inclined grooves N¹ to receive the flanged portions M' of the bars M, and plates N
are bolted to the bosses N in such positions as to overlap the edges of the flanges M'
to keep the bars M and bosses N in sliding connection with each other. Anti-
friction rollers may if desired he provided upon the bars M and bosses N to
minimise the friction of the parts which slide past each other. N³ is a flexible
casing of leather which is arranged to make a tight joint with the shaft B and also
with the extensions L' as shown in Fig. 3, so as to keep the rubbing-surfaces
of M and N free from dust, without hindering their movement relatively to each
other.
The bent edges K2 of the husking plates engage with flanges L³ upon the
plates L' as shown in Figure 4.
Rubber buffers O are interposed between each husking plate K and batten L;
they are in the form of hollow cylinders and are placed over screws or studs
provided in suitable positions upon the battens. The said buffers serve two
purposes, that is to say they keep the bent edge K' of each husking-plate against
the flanges L of the plates L' and they enable the said edge K2 of the husking-
plate to yield momentarily should the said husking plate meet any considerable
resistance as it travels with the cylinder A in the direction indicated by the arrow
in the said Figure 4.
The means employed for sliding the bosses N along the shaft B are important
features of this invention and will now be described:
P is a collar adapted to slide end wise upon the shaft B and to rotate therewith.
A casting Qembraces the said collar between flanges P¹ formed on the latter, in
such a manner that the collar is free to turn within the casting. RR are screwed
spindles which turn in bearings in a fixed frame R' and are passed through screwed
holes in extensions or lugs Q on the casting Q. The screwed spindles are pro-
vided with worm wheels R2 geared with worms R³ on the worm shaft R* which
latter turns in bearings in the frame of the apparatus and is provided with the
handle R'.
SS are rods secured to lugs P' upon the collar P; the said rods pass through

page_text: holes in the end of the cylinder A to the bosses N, to which they are secured.
TT are vanes arranged in two rows, one at each side of the cylinder A. They
are either permanently fixed thereon, or adjustable about pivots T' upon the
cylinder, by means of longitudinal bars T2 which slide in the direction of their
length and are suitably connected to the vanes. The said vanes are adjusted at
such an angle with the plane in which they travel that they act as conveyors to
cause the material in the chamber E to pass along gradually therein, from the
inlet end to the outlet end thereof, or to cause it to be retarded in its passage as
may be desired; thus if the cylinder A be rotated at a given speed the vanes T
determine the length of the period during which the material is subject to the
action of the husking-plates. The said vanes and means for adjusting them have
been described in the Specification of prior Letters Patent No. 8300 A.D. 1884
granted to me.
The aforesaid improved mechanism operates as follows:-
1
The coffee or other material to be husked or hulled is placed in the hopper D³.
The shaft B is rotated and the cylinder A revolves therewith. The wheel F
delivers the material from the hopper D2 into the chamber E by way of the
channel D³. The vanes T feed the said material through the chamber while the
husking plates K exert pressure upon it. The said material is rolled between
the husking plates and the perforated wall E' so that the husk or hulls are removed.
The said husks or hulls pass out of the chamber E into the sieve box E together
with the husked or hulled material.
The distance between the said husking-plates K and the wall E' is regulated to
suit the character of the material operated upon, in the following manner :- -When
the worm shaft R is rotated by means of the handle R, the screwed spindles R
are rotated, and they, by moving the casting Q, effect the end wise movement of
the collar P, which, by means of the rods S, slides the bosses N along the shaft B.
The said bosses N, when thus moved act upon the inclined edges of the bars M by
sliding upon the same and move the battens L inward or outward, as the case may
be, to or from the periphery of the cylinder A. The ends K2 of the husking-plates
partake of the movement of the battens and are thus caused to approach to or
recede from the perforated wall E, turning, in that movement, about the shafts J.
As an alternative I may provide at the ends of the said battens anti-friction
rollers, and upon the shaft B I may place cam plates suitably slotted, and arranged
so that when they are rotated they move the said battens in or out.
With reference now to the alternative construction of apparatus illustrated in
Figures 5, 6, and 7, I secure upon the outside of the husking cylinder A and
parallel with its axis, suitable plates, hereinafter termed base plates J¹, each
provided with a raised edge or bend J or being otherwise formed so that one
edge K' of each husking plate K, which also is bent or otherwise made of hooked
form, will hook under the raised or "hinge" edge J' of the base plate, about which
the said husking plate turns as about a hinge.
UU are castings secured upon the exterior of the husking-cylinder A and
provided with a number of recesses U¹. A shaft V is secured in each casting
so as to pass across the said recesses. The said castings are so formed as to
cover the shaft V so that the latter has not to be dragged through the material
during the rotation of the cylinder. Arms W are keyed upon the portions of
the shaft which pass across the said recesses, an arm being appropriated to each
husking plate, and arranged to bear upon the back thereof. The bosses of the
arms W fill the said recesses. The said arms W are provided with projections Wo,
which, when the said arms are in their normal positions, as shown in Figure 6,
serve to ensure the retainment of the bent edges K¹ of the husking-plates K
in engagement with the base plate. Upon the ends of each of the shafts V
arms Vare secured; the said arms pass through the cylinder wall to the interior
of the cylinder and their inner ends are suitably shaped for a purpose hereinafter
Bet forth.
Upon the shaft B, which in this instance is hollow for considerable portions of

page_text: its length at the ends, two discs B are fixed, and two discs B° are movable in the
direction of the length of the shaft. The discs B support the cylinder and serve
as guides for rods S by which the two discs B are connected.
A rod X is passed axially into the shaft B, at one end of the latter, and is
connected at its inner end to one of the discs B by the arms X', each of which is
attached at the middle of its length to a sleeve X capable of sliding on the shaft B;
the outer end of the rod X is screw-threaded to receive a hand-wheel Y, which
bears upon the bottom of a recess therein. The said hand wheel, when operated,
moves the rod X end wise and the said rod moves the discs B' along the shaft B.
The discs B have inclined or helical grooves B in their peripheries, into which
the ends of the arms V₁ enter, so that when the discs 13 are moved endwise in the
manner described the said grooves turn the arms V₁, the inner ends of which are
curved at the sides as shown, or are otherwise suitably shaped to move freely in
the grooves, and thereby the said arms V₁ turn the shafts to which the said arms
and the arms W are fixed; thus the arms W are caused to force the free ends of
the husking-plates K towards the surface of the cylinder A against the resistance
of the rubber buffers O, or are caused to move in the opposite direction to allow the
free ends of the husking-plates K to move away from the surface of the cylinder,
under the action of the said elastic buffers O.
Upon the rod X is a circular nut or hand-wheel Y' for the purpose of locking
the wheel Y in place when the discs B³ have been properly adjusted.
The opposite end of the shaft B is fitted with well-known means for adjusting the
vanes T, of a similar character to the aforesaid devices employed for adjusting the
discs B³.
In the modification illustrated in Figures 8 and 9 each base-plate J' is made
with a channel or groove J³ to receive a bar a. The said channels are covered by
cover-plates J.
Discs B arranged to slide upon the shaft B and operated in the manuer herein-
before described with reference to the discs B in Figure, are provided with
arms which extend through the wall of the cylinder A and engage with the
bars a.
Buffers are interposed between the husking-plates K and the cover-plates J,
and bolts c are passed through the husking-plate and buffer, and through slots a¹ in
the bars a. The sides a² of the slotted portions of the bars are inclined as shown,
and a nut c¹ with correspondingly inclined faces c² is screwed upon each bolt cas
shown so that the inclines a² and c² bear against each other.
The heads of the
nuts are reduced, and enter holes in the bottom of the groove J³, the said heads
and holes being so formed that the nut is prevented from slacking back.
When the discs B are moved along the shaft B they move the bars a endwise
in the grooves J³, by means of the arms b When the said bars are thus moved,
the inclines a either pull the bolts c and husking plates K inward, towards the axis
of the cylinder or allow them to move outward, under the action of the buffers O,
as the case may be.
In the modification illustrated in Figures 10 and 11 levers W are pivoted in
suitable bearings on plates I' secured upon the exterior of the husking-cylinder A,
parallel to the base plates J. The said levers are provided with extensions w¹,
and a sliding bar a, shown separately in Figure 12 is received in a groove l' in each
plate and is connected by rods a³ to arms e formed upon bosses arranged to
slide upon the shaft B and operated similarly to the bosses B herein before
described with reference to Figures 5 and 6. The sliding bar a covers the openings
through which the arms e pass, so that dust is prevented from passing through the
said openings into the cylinder. Upon the said bars, above inclined surfaces a
formed on projecting portions of the said bars, short pieces are secured; the
said pieces are provided with overhanging flanges g' which have inclined surfaces g
formed thereon parallel with the inclines a² on the bar a. The extensions w¹ of the
lever W are received between the said inclines a² and . The bars a are ordinarily

page_text: kept in place by T-headed bolts h screwed into them; the heads of the said bolts
are received in T-shaped slots i of suitable length, formed in the plates I¹. By
giving the bars a sufficient endwise movement the inclines a' and 9' can be moved
clear of the extensions w¹ of the levers W which can then be tilted clear of the
husking plates so as to enable the latter to be removed. jjare pockets in the
periphery of the cylinder A to receive the extensions w¹ so that they may not come
into contact with the cylinder surface in such a manner as to inconveniently limit
the aforesaid operation of tilting. The said levers W are provided with pro-
jections W for the same purpose as the projections Wo hereinbefore described
with reference to Figure 6. When the bars a are moved in the direction of their
length the levers W are operated by the said inclines a³ ³ to move the free ends
of the husking-plates towards or away from the periphery of the cylinder.
The means whereby the arms or levers bearing upon the husking-plates are
operated may be varied as desired, without departure from the nature of my
invention; I do not limit this part of my said invention to the use of the particular
means hereinbefore described for that purpose, but I wish it to be clearly understood
that I regard as features of especial value, facilities for effecting with ease and
rapidity the adjustment of the husking plates K and the vanes T.
In any of the apparatus hereinbefore described I employ, where necessary,
suitable flexible dust guards such as are hereinbefore described with reference to
Figure 3, around parts which have movement in openings such as would otherwise
permit of the passage of dust.
As a further alternative, where the husking plates are secured in place upon the
cylinder and their movement about the raised or hinge edge of the base plate is
controlled simply by a buffer or spring and a bolt as described in my Specification
of Letters Patent dated 27th May A.D. 1884, No. 8300, I employ in combination
therewith novel arrangements such as are illustrated in Figure 13, for preventing
the husking plates from becoming disengaged from the base plates by the breaking
of a bolt, which, as described in my said prior Specification, is passed through each
husking plate at a point intermediate between its hooked edge and its free edge.
In the said Figure 13 o is a bolt passed through the buffer O into the base-plate J';
the said bolt keeps the buffer in position and its head limits the movement of the
busking-plate K away from the cylinder. In suitable bearings p upon the periphery
of the cylinder A are a series of spindles 9 which are parallel with base-
plates J and with the axis of the cylinder and are provided with cams q' or with
eccentrics or other suitable projections, one spindle being appropriated to each
series or portion of a series of husking plates and one, two, or more projections being
appropriated to each husking plate. Each said projection is so arranged that with
its spindle 9 in its normal position the cam q¹ will prevent the husking plate from
becoming disengaged from the base plate even if the aforesaid bolt o should break.
A suitable handle q' is provided upon each spindle, whereby it may be turned to
move the cams q' out of engagement with or out of proximity to the husking plates,
to permit them to be removed when desired. The said handles are preferably so
arranged that while they and the spindles are in a position in which the husking
plates are not locked in place, the husking chamber in which the cylinder is placed
cannot be closed; this arrangement, when the husking plates are not secured,
Instead of
prevents the machine from being closed by careless attendants.
employing special shafts with the said projections thereon, eccentrics, cams, or other
projections may be formed upon the shafts on which the herein before mentioned
two-armed levers are placed, and the said shafts may be turned by handles arranged
as described while still serving as bearings for the two-armed levers, which in such
a case would not have the aforesaid projections W° thereon.
Instead of constructing the outer cylinder or husking chamber in the manner
which has hitherto been customary, that is to say of staves arranged in such a
manner that several bolts must be withdrawn in order that access to the interior of
the cylinder may be obtained, I form one section or segment of the cylinder wall

page_text: as a door with suitable hinges upon which it may turn. The edges of the said door
are bevelled, in order to enable it to open readily, and so that it may when closed
make a tight joint.
Further, in order that the wire cloth, or the like, which forms part of the wall of
the said outer cylinder, may be secured in place without such damage as now arises
from the prevalent practice of nailing the said wire cloth to the staves, I bolt or
otherwise secure the wire cloth to suitable bars or the like before it is placed in the
husking machine and I form in other staves or standards placed, as is customary,
around the husking chamber, suitable recesses to receive the aforesaid bars, and in
the said bars and staves I form bolt holes, so that simply by placing the bars in
place in the recesses in the staves and passing suitable bolts both, the said bars and
the wire cloth secured to them are retained in place in such a manner that they can
be readily removed from the machine and as readily replaced therein, without such
damage to the machine as has hitherto occurred from the repeated driving of nails
or spikes into the staves at different places. I preferably form the wire gauze and
the bars to which it is secured in such a manner that when placed in position in the
husking chamber as above described and without further fitting or manipulation, the
true cylindrical form of the interior of the said chamber is preserved.
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. The combination with a rotatable husking cylinder having husking-plates
hinged thereto, of battens or plates in elastic connection with the husking-plates
and arranged in or upon the periphery of the cylinder, and means for moving the
said battens or plates inward or outward, for the purpose specified.
2. The combination with a rotatable husking-cylinder, of vanes and husking-
plates hinged or pivoted thereon, and adjustable from the exterior of the apparatus,
substantially as herein before described, for the purposes specified.
3. The combination with a rotatable husking-cylinder of the said battens or
plates, bosses on the shaft of the cylinder in sliding connection with inclined
portions of the battens or plates, and the means for moving the bosses, substantially
as hereinbefore described, for the purpose specified.
4. The combination with a rotatable busking-cylinder having husking-plates
hinged thereto, of shafts placed in bearings on the exterior thereof, fitted with arms
bearing upon the husking-plates, and sliding discs upon the shaft of the husking-
cylinder adapted to operate the said shafts by means of suitable arms keyed to the
latter, substantially as hereinbefore described, for the purpose specified.
5. The combination, with a rotatable husking-cylinder having husking-plates
hinged thereto, of sliding bars in the periphery of the cylinder, bolts connected to
the husking-plates and operated directly by the sliding bars, and sliding bosses on
the shaft of the cylinder connected to the said sliding bars, substantially as herein-
before described for the purpose specified.
6. The combination with a rotatable husking-cylinder having husking-plates
hinged thereto, of two-armed levers pivoted upon the periphery of the said cylinder
and means for operating the said two armed levers, substantially as hereinbefore
described for the purpose specified.-
7. The combination, with a rotatable husking cylinder having husking-plates
hinged thereto, of two-armed levers pivoted upon the periphery of the said cylinder,
sliding bars upon the periphery of the cylinder to engage with and operate the said
two armed levers, and means for operating the said sliding bars, substantially as
herein before described, for the purpose specified.
8. The combination, with the said two-armed levers of a sliding bar of the kind
herein before described with reference to Figures 10 11 and 12 of the accompanying
drawings, and pockets in the periphery of the husking-cylinder, for the purposes
specified.
9. The means for axially adjusting the sliding bosses upon the shaft of the

page_text: husking-cylinder substantially as herein before described with reference to Figures 1
and 2 or to Figures 5 and 6 of the accompanying drawings for the purpose
specified.
10. The combination with arms or levers which operate the husking-plates of
cams or projections W thereon, substantially as hereinbefore described, for the
purposes specified.
11. The cams or projections on special shafts or on the shafts of the two-armed
levers for preventing the husking plates from becoming disengaged from their
hinges or pivots, substantially as hereinbefore described.
12. The employment of dust guards, substantially as hereinbefore described, for
the purpose specified.
13. The improved husking or hulling apparatus substantially as hereinbefore
described with reference to Figures 1, 2, 3 and 4, or to Figures 5, 6 and 7 or to
Figures 8 and 9 or to Figures 10, 11 and 12 or to Figure 13 of the accompanying
drawings, and operating as specified.
