Improvements in Grain Separators and in Screens therefor.
I, CHARLES CLOSz, of St. Ansgar, in the County of Mitchell, and State of lowa,
United States of America, Miller, do hereby declare the nature of said invention for
IMPROVEMENTS IN GRAIN SEPARATORS AND IN SCREENS THEREFOR to be as
follows:-
My invention is directed to the improvement of machines for separating and
screening grain from foreign substances, and particularly to such machines for
effecting a preliminary separation of the grain from such matter as nails or pieces of
metal and gravel that are sometimes found in the grain, and if not removed would
be injurious to the grinding-rolls. My improved machine also effects the separation
from the grain of straw, sticks, weeds, husks, &c., that come with the grain. In my
improved machine the grain is separated from such matter by a regular and uniform
overflow-discharge from the opposite sides of a tray having a horizontal longitudinal
movement only, and which serves for accumulating and retaining therein such foreign
matter as by its weight must settle and remain in the tray. The provision for such
uniform side discharge avoids the objection of a throwing or jumping endwise dis-
charge due to an endwise movement, which tends to carry with the grain the nails
and other heavy matter which it is so important to retain in the device, because a
side overflow-discharge produced by an endwise motion of the device can have no
throwing or jumping movement toward such side overflow, and hence the latter must
be even and not liable to carry with it matter heavier than the grain. To facilitate
such side overflow from the accumulator and retainer, it is made in the form of a tray,
foraminated for a bottom discharge of the small stuff and seeds which come with the
grain and thereby prevent the packing and choking in the tray, which would very
materially hinder or impede the side overflow discharge and render the heavy matter
liable to pass over with the grain, and thus defeat the object of the accumulator-
tray. The grain is supplied to the hopper of the machine from a spout or elevator,
and passes by a regular overflow-feed to the platform-separator, through which the
grain, small stuff, and seeds pass down into the accumulator-tray and the side over-
flow and the bottom discharge therefrom pass into separate bins or elevators, or into
the same bin, as may be desired. Provision is made for delivering the grain to the
foraminated tray through a long slot and in a ridge-like body, so that it can spread
evenly over the tray, not end wise but toward the opposite sides thereof, and such
side spreading is regulated and controlled by automatic gates which form the hinged
walls of said long slot. Provision is made for an upward-suction air-blast through
the separator-platform, from below and over the same from the hopper end, and for
carrying the dust and light stuff away from the machine outside of the mill, and for
regulating such air-blast.
The chaffing screen or riddle employed with my grain separator is constructed of
corrugated sheet metal, and is intended particularly for effecting a preliminary
separation of straw, sticks, weeds, husks, bits of cob, silk, and nails from the grain.
This improvement embraces the construction of a sheet metal separator wherein ridges
are inclined upward between approximately heart-shaped openings and terminate in
spear-points at the rear edge of each opening to form shallow side inclines between
and terminating in the lowest front edges of the said openings, so as to give a free
discharge of the grain through the openings, while the straw and other long stuff*
pass off over said inclined ridges and spear-points in an outward end discharge under
the longitudinally-reciprocating movement of the platform. The termination of the
inclined ridges in spear-points is to give enlarged rounded ends to the openings on each
side of the spear-points; to allow for the free passage of air-currents; to more

page_text: effectually assist in raising the straw as it rides over the inclined ridges, and to cause
the grain to pass to the enlarged ends of the openings along the shallow side slopes
formed by said ridges.

Improvements in Grain Separators and in Screens therefor.
I, CHARLES CLOSz, of St. Ansgar, in the County of Mitchell and State of Iowa,
United States of America, Miller, do hereby declare the nature of my invention for
IMPROVEMENTS IN GRAIN SEPARATORS AND IN SCREENS THEREFOR, and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My invention is directed to the improvement of machines for separating and
screening grain from foreign substances, and particularly to such machines for
effecting a preliminary separation of the grain from such matter as nails or pieces of
metal and gravel that are sometimes found in the grain, and if not removed would be
injurious to the grinding-rolls. My improved machine also effects the separation
from the grain of straw, sticks, weeds, husks, &c., that come with the grain. In my
improved machine the grain is separated from such matter by a regular and uniform
overflow-discharge from the opposite sides of a tray having a horizontal longitudinal
movement only, and which serves for accumulating and retaining therein such foreign
matter as by its weight must settle and remain in the tray. The provision for such
uniform side discharge avoids the objection of a throwing or jumping end wise dis-
charge due to an end wise movement, which tends to carry with the grain nails and
other heavy matter which it is so important to retain in the device, because a side
overflow-discharge produced by an endwise motion of the device can have no
throwing or jumping movement toward such side overflow, and hence the latter must
be even and not liable to carry with it matter heavier than the grain. To facilitate
such side overflow from the accumulator and retainer, it is made in the form of a tray,
foraminated for a bottom discharge of the small stuff and seeds which come with the
grain and thereby prevent the packing and choking in the tray, which would very
materially hinder or impede the side overflow-discharge and render the heavy
matter liable to pass over with the grain, and thus defeat the object of the accumu
lator-tray. The grain is supplied to the hopper of the machine from a spout or
elevator, and passes by a regular overflow-feed to the platform-separator, through
which the grain, small stuff, and seeds pass down into the accumulator-tray and the
side overflow and the bottom discharge therefrom pass into separate bins or elevators,
or into the same bin, as may be desired. Provision is made for delivering the grain
to the foraminated tray through a long slot and in a ridge-like body, so that it can
spread evenly over the tray, not end wise but toward the opposite sides thereof, and
such side spreading is regulated and controlled by automatic gates which form the
hinged walls of said long slot. Provision is made for an upward-suction air-blast
through the separator-platform, from below and over the same from the hopper end,
and for carrying the dust and light stuff away from the machine outside of the mill,
and for regulating such air-blast.
The chaffing screen or riddle employed with my grain separator is constructed of
corrugated sheet metal, and is intended particularly for effecting a preliminary
separation of straw, sticks, weeds, husks, bits of cob, silk, and nails from the grain.
This improvement embraces the construction of a sheet metal separator wherein
ridges are inclined upward between approximately heart-shaped openings and
terminate in spear-points at the rear. edge of each opening to form shallow side
inclines between and terminating in the lowest front edges of the said openings, so as
to give a free discharge of the grain through the openings; while the straw and other

page_text: long stuff pass off over said inclined ridges and spear-points in an outward end dis-
charge under the longitudinally-reciprocating movement of the platform. The
termination of the inclined ridges in spear-points is to give enlarged rounded ends to
the openings on each side of the spear-points; to allow for the free passage of air-
currents; to more effectually assist in raising the straw as it rides over the inclined
ridges, and to cause the grain to pass to the enlarged ends of the openings along the
shallow side slopes formed by said ridges.
The accompanying drawings illustrate my invention, which I will now describe
in connection with such drawings, and will specifically designate in the concluding
claims the parts and combination of parts which constitute my improvements.
Referring to the drawings.

shallow side slopes formed by said ridges.

The separating, accumulating, and retaining parts are arranged in a box a, and
with it they form the separator device which is suitably mounted or suspended in a
frame for longitudinal movement only. At the head end of this box is arranged a
hopper b, into which the grain is fed and which reciprocates with the box.. This
hopper is made with an overflow-feed at its rear side by means of a gravity-closing
gatec, which is pivoted so as to hang in such relation to a ridge c' on the bottom of
the hopper as to allow the grain to push the gate open by the reciprocating move-
ment of the box and the weight of the grain, and thus cause the grain to pass out of
the hopper over the ridge with a regular and even feed under the gate and over the
ridge between the hopper and the rear wall of the box. A bottom d under the
hopper has an overflow-ridge d', over which the grain is caused to pass with a
regular and even feed to a separator-platform by the reciprocating movement of the
box.
On a level with this hopper bottom d, is placed a separator-platform or screen.
This platform or screen is made of sheet metal and formed with longitudinal ribs or
corrugations e, which extend in parallel relation the length of the platform and at
such height and distance from each other as to form channels between them.
Within these channels are openings, which are of oblong form or configuration and
stand cross-wise within said channels. As shown in the drawings, said openings f,
are approximately heart-shaped and extend from the base of one longitudinal rib or
corrugation e, to the base of another and adjacent corrugation. These oblong or
heart-shaped openings are preferably formed with their forward edges nearly
straight and beveled downward and their lateral or inner edges rounded into
enlarged ends i. Between each of these heart-shaped openings and centrally and
longitudinally between the corrugations, the channels are formed with ridges g.
These ridges, extend upward at an inclination from the front edge of one opening
to the rear edge of the next opening where the said ridges terminate in spear-points h;
said spear-points standing toward the discharge end of the screen or separator plat-
form, and forming the highest point of the ridges. These ridges y, are intersected
by the openings, and form shallow inclines e, on each side of the ridges and along
the ribs, which said inclines slope downward and inward laterally from the spear-
points at the highest curved edge of one opening to the lowest forward edge of the

page_text: next opening. This construction gives two inward or laterally sloping surfaces e¹,
between each of the central ridges g, and the adjacent longitudinal ribs e.
In the operation of the apparatus the central ridges g, serve to separate the mass
as it is moved longitudinally over the openings; the laterally sloping surfaces e',
causing the straw and other long stuff' or foreign matter to pass over the openings
without catching therein, and the grain and heavy particles to settle on the sloping
sides and pass through the curved ends i, of the openings which are enlarged at
each side of the spear points, h, which latter only project into the openings at the
rear edges thereof.
For some distance the receiving end of the screen or separator platform is made
without the openings; and the central ridges g, instead of being inclined stand at
a height on a level with the spear-points for the purpose of causing long stuff in the
mass to turn lengthwise before it reaches the first openings and thereby place such
stuff in position to move along over the central ridge, the sloping sides, and the
openings.
The approximate heart shape of the openings, the inclined ridges 9 intersecting
the openings, and the sloping sides c¹ of the ridges make a separating-platform
specially and advantageously adapted for a preliminary separation of grain from
long stuff.
This platform is hinged at its hopper end to the frame by the pivot-pins 2, Fig. 3,
and is adjusted higher or lower at its delivery end by the screw-bolts j, passing
through slots in the sides of the box, to which the platform is clamped by said bolts
when set to the desired inclination to increase or diminish the passage of the grain
over the platform. The stuff passing off the end of this platform drops into a closed
end of the box a and is discharged therefrom by means of a door 1, which opens
and closes with a gravity and flap movement by the reciprocating action of the box,
and thus provides for the discharge of the stuff passing over the platform-separator
from a box which is closed at the discharge end, as seen in Fig. 1, for a purpose to
be presently stated. Directly under this sheet-metal separating-platform I provide
a foraminated receiving-tray m, closed at its ends, into which all the matter passing
through the separating-platform is received and from which the grain is discharged
by overflowing its two opposite sides in a way which I shall presently state. Between
the separating-platform and the bottom tray I provide the box with a long hori-
zontal hopper or chute, formed by two boards n inclining downward from the inner
walls of the box, so as to form a middle slot p, having a length equal to that of the
separator-platform and of the tray, and wide enough to let the grain pass freely
down through it all along its length. This slot is some distance above the bottom
of the tray, and for the purpose of delivering the grain upon the tray in an
underflow-ridge or strip-like body I extend the walls q of the slot downward to near
the bottom of the tray, and thereby form a long narrow trough which opens into the
middle of a wide foraminated tray. I hang the walls q of this slot below the inclined
sides n, so as to yield outward from each side of the slot, and for this purpose I
hinge said walls to the under side of each inclined board along the slot-forming edge
by straps, or otherwise, so that they will hang down and be free to be pressed
outward, so as to increase the width of the space between their lower edges, and
thereby give a free uniform sheet-feed of the grain from the slot under the edges of
the swinging walls along the middle of the length of the tray, and thus distribute it
evenly thereon toward each side by the longitudinal shaking action of the device.
The hanging walls for this purpose have only a limited outward swinging movement
caused by the pressure or gravity of the grain in seeking an outlet from between
them and in effecting such outlet by an underflow. The outward swinging move-
ment of the walls is limited by the manner in which they are hinged, so that their
upper beveled edges will form stops which abut against the under sides of the
inclined boards n, which form the slot, and thus allow the said walls to open
sufficiently to insure the proper underflow and prevent the choking of the slot.
The tray is preferably made of sheet metal of a length equal to that of the hopper-
slot and of a width a little less than that of the box, as shown in Figs. 1, 4, and 10,

page_text: and is secured in a horizontal position and slightly inclined upward at each end
at m', Fig. 1, for the purpose of preventing an end wise throwing action of the grain
and its collection against the closed ends of the tray, which with a perfectly flat
bottom it would be liable to do, and thereby to cause an unequal overflow, which
might carry off such matters as are intended to be retained in the tray. The sides s
of the tray are preferably made vertical and adjustable and of sufficient height above
the bottom to retain the heavy matters, while the grain will overflow these sides
in a thin sheet and pass down upon the inclined bottom t of the box to a suitable
receptacle, as seen in Figs. 1 and 4. I prefer to make the tray-sides of tin and to
bend their upper edges t¹ inward, so as to form projecting lips to prevent or help to
prevent the passage of nails or other heavy particles with the overflow moving grain.
I prefer to make the sides in sections and to adjust them by slots u and screws r, as
seen in Fig. 8, to suit the end throw of the tray and prevent any undue overflow, and
to set the end sections, if necessary, higher than the middle section.
I prefer to construct the bottom of the tray with a longitudinal central ridge W,
and to form the tray-bottom into two shallow foraminated trays, as seen in Figs. 9
and 10. The ridge W is formed integral with the shallow-trays and is provided
with lateral corrugations w. To each lateral edge of the corrugated ridge W is
provided a longitudinal flange V, of sheet metal or other suitable material. These
flanges V, assist in agitating the grain and separating the heavy particles therefrom
as it moves laterally off the corrugated ridge W.
For effecting the separate discharge of the small seeds and fine stuff from the
bottom of the tray through its openings, I provide it with a bottom, inclining
toward the discharge end of the separator-platform. This bottom discharge for
small stuff is important to prevent the packing or clogging of the grain in the
bottom of the tray, because if the grain should pack or clog in the tray the nails
and heavy particles would be liable to pass off with the moving grain in the side
flow. This side and bottom discharge from the tray keeps it always in condition to
retain the heavy matters, which can neither pass through the bottom openings or
over the sides, and it will be understood that the bottom openings are only large
enough to permit the small seeds, stuff, and dust to pass through them to keep the
grain moving freely over the surface of the tray. The heavy matters retained in
the tray can be removed through doors in the sides of the box as may be found
necessary.
Referring to Fig. 4, it will be seen that the tray is of less width than the box a,
so as to leave a space between them for the overflowing grain to pass down at each
side of the box upon the inclined bottom t, as seen in Fig. 1.
The separating device is preferably supported so as to have only a horizontal or
longitudinal movement, which I find is best adapted to the side overflow-discharge
from the tray and gives a regular and uniform overflow, whereas if such overflow
were in the direction of the movement of the tray it would be more or less irregular
and cause a throwing or jumping of the grain in a body, which would be liable to
carry with the overflow the matters which should be retained in the tray. For this
purpose the box of the device is supported by four spring-plates y, two on each side,
which are attached to the top of the box and to the bottom of the frame, and the
device is operated by a suitable eccentric on a horizontal cross-shaft supported in
the frame at the head end of the device, and which shaft is operated by a pulley
and belt from any suitable power.
This machine is intended to be used in the mill or in what is known as an
elevator for handling or storing grain, and in such use no air-blast is required for
the separation and cleaning which is effected by the tray. For the separating
action of the top shaking platform, however, I use a suction-blast, which I will now
describe. At the tail or discharge end of the machine a fan-case 2 is mounted upon
the frame and opens into the box above the said platform by a passage 3 at each
side of the case, and which communicates with the latter by the openings 4, so that
the fan 5, being revolved, sucks the air upward into the case and forces it out of the
discharge-spout 6, which may extend to any convenient place outside the mill to

page_text: carry the dust and light stuff outside of the room. The suction-blast thus created
is directly from the head end of the machine through the opening 7 beneath the
platform and through the opening 8 above the platform at the side of the hopper,
so that the draft is both under and above the platform, up through the openings
therein, and along and over the platform and through and over the feed-flow from
the hopper, the air-currents passing off through the fan-case. This under and upper
suction causes separate and distinct air-currents and gives a very effective clearing
action to the grain and carries the dust out of the room. In this upward suction-
blast the form of the openings and the action of the spear-point ridges in the
shaking platform give the advantage of the full and free force of the air-currents up
through the grain and straw and lifts and loosens the latter over the openings, so
as to free the grain and carry off the dust. To obtain the full effect of such suction-
blast, the discharge end of the box and the space over the platform are closed, so
that the air-blast must be drawn from the two openings 7 and 8 beneath and above
the receiving end of the platform, while the gravity-closing action at the discharge
end of the box will tend to be kept closed by the force of such suction and will
open by a flap action to discharge the matter passing off from the end of the
platform.
For regulating the force of the suction-blast I provide an automatic valve 9
within the vertical passages 3 3, which connect the fan-case with the interior of the
box. This valve 9 is pivoted so as to hang down to open the passage and to swing
up to lessen the area of the passage, such closing action being regulated by the force
of the air-blast. The pivot of this valve extends outside of the case, and has an
arm 10 extending down coincident with the valve, so as to indicate the position of
the latter at all times, and by means of pins 11 to regulate and determine the
extent of the closing movement of the valve by placing the pins in holes 12 in the
casing, so as to form stops, as seen in Fig. 7. This valve-arm may be provided
with a weight 13, which can be adjusted by a screw to suit the force of the suction-
blast, the object being to render the force of the blast as uniform as possible. The
normal position of the valve is vertical to allow it to catch the blast and be swung
up thereby according to the force of the blast and the adjustment of the weight,
and thus regulate the force of the suction-blast according to the speed of the fan
and to suit the character of the cleaning and separation. In this construction it is
important to notice that the hopper is mounted upon the shaking platform, while
the fan-case 2 is mounted upon the fixed frame, so that the suction-passages 3 extend
into the box-space above the platform by the short pipes 14, extending through
openings 15 in the top of the box, which allow the latter to move over said pipes in
its reciprocating movements, as in Fig. 6.
The overflow-feed from the hopper to the bottom d, and the overflow-feed from
the latter over the ridge d', give a uniform distribution of the grain into the separate
channels of the platform, the corrugations of which are on a level with the platform-
overflow ridge d', as seen in Fig. 1.
It will be observed that the inclined ridges g of the separator platform serve to
give increased stiffness to the platform; and are made by comparatively shallow
corrugations, which are about half the height of the unbroken corrugations. This
construction forms a rigid sheet-metal separating-surface of unbroken parallel
longitudinal corrugations, intermediate interrupted inclined ridges terminating in
spear-points, slopes on each side of said ridges, and openings crossing said ridges and
extending on each side of the said spear-points.
It will be seen that the spear-points give the rounded ends to the openings, so
that they are thereby made of circular and enlarged form at each end, and the grain
is more easily passed through it by reason of the spear-point standing at the
middle of the length of the ends of the latter and extending around each side of
the point.
The extent of the space between the openings will be governed by the special use
of the screen.
The platform may be used with any form and arrangement of under-shaking

page_text: screens and with or without a fan-blast; and I prefer to form it of a single sheet of
metal and to secure it to a frame or side bars.
