SHAKING GRAlN-SEPARATOR.
SPECIFICATION forming part of Letters Patent No. 766,538, dated August 2, 1904.
Application filed July 15,1901. Serial No. 68,276. (No model.)
To all whom it inn/y concern.-
Be it known that I, F MARION SMITH, a citizen of the United States, and a resident of Nashville, in the county of Barry and State 5 of Michigan, have invented a new and useful Improvement in Shaking Grain-Separators, of which the following is a specification.
This invention relates to a machine for separating grains of different size wherein a shak- Io ing shoe or frame is provided with separating-screcns, one below the other, and means for conveying the different grades of material over the screens and to the proper discharge-openings.
The machine herein described is especially useful for the separation of the hulled kernels of rice or oats from the nnhulled kernels, usually called paddy, which have to be returned to the hulling-machine.
The object of the invention is to produce a separating-machine of this character in which the shaking-shoe is provided with a novel combination of screens, conveyers, and cutofl valves for insuring a more thorough and complete separation and a more convenient delivery of the separated materials.
In the accompanying drawings, Figure 1 is a longitudinalsectional elevation of a shaking separator embodying the invention. Fig. 2 3 is a transverse vertical section on line 2 2, Fig. 1. Fig. 3 is a horizontal section on line 3 3, Fig. 1. Fig. 4 is an enlarged sectional view of one of the cut-off valves. Fig. 5 is a side elevation of the adjusting device of the cut-off valves. Fig. 6 is a fragmentary transverse section of the same on line 6 6, Fig. 5.
Like letters of reference refer to like parts in the several figures.
A represents the stationary frame of the 4 machine, of any usual or suitable construction; B, the feed-hopper arranged in the upper part of the frame at the front end thereof; O, the shaking-shoe, which is supported in any desirable manner in the frame below the feed-hopper, as by flexible hangers 0, and D an actuating-eccentric or the like connected with the shaking-shoe by a rod (I or other suitable means.
the smaller perforations being in the front portion a of the screen and the larger perforations in the rear portion a. The lower screen I is shorter than the first screen E and is located beneath the rear portion 0 thereof, extending from beneath the tail end of the upper screen forwardl about half the length of the upper screen.
F is a conveyer-plate located beneath the front portion a of the upper screen E for receiving the hulled grain or clear separated material passing through the same. This conveyer-plate is V inclined rearwardly and terminates above the head of the lower screen E at a vertical transverse partition), which is provided with an openingf", extending above and below the rear end of this conveyer-plate, so that the hulled grain falling upon the plate F is discharged rearwardl y through said opening.
G is an upright spout or chute which is arranged in front of the lower screen and in front of the partition?" and which connects at its lower end with a conveyor-plate H, located beneath the lower screen E and inclined rearwardly. This plate H receives the hulled grain or clear separated material from the lower screen and is provided near its rear end with a discharge-spout It for delivering the hulled grain.
1 represents a rearwardly-inclined cut-off conveyer-platc arranged underneath the rear portion 6 of the upper screen and above the discharge-openingf" over the rear end of the front conveyor-plate F. This cut-off plate extends rearwardly nearly to a point beneath the rear end of the upper screen.
J is a forwardly-inclined conveyer-plate arranged underneath the cut-off plate I for receiving the clear separated material from the same and extending from beneath the rear end of the plate I-to the upright spout Or, so
that the hulled grain which falls upon this forwardly-inclined conveyer-plate J is delivered by the same to the spout G.
K represents a forwardlyinclined conveyer-plate which is arranged below the forwardly-inclined plate J and above the lower screen E for conducting the cut-off material from the tail of the cut-off plate I to the lower screen. This plate K extends rearwardly beyond the rear end of the cut-off plate I and is provided at its rear end with an upright wall 76, which extends upwardly to the tail end of the upper screen E. The front end of the plate K is separated from the rear wallof the spout G by a passage it, through which the material passes from the plate K to the head of the lower screen.
L is a cut-off conveyer-plate which is arranged beneath the lower screen E and above the lower conveyer-plate H. This plate extends from the rear wall of the spout Gr rearwardly to a point beneath the tail end of the lower screen and receives the grain passing through the latter.
The upper cut-off plate I is provided with several cut-off openings d, arranged one behind the other and extending across the plate. Each of these openings is controlled by a cutoff valve M in such manner that when the valves are closed the plate is tight and discharges all of the material falling upon the plate over the tail end thereof, while when one of the valves is opened the material falling upon the portion of the plate above the open valve passes through the opening and the material falling upon the plate below the open valve is cut off and discharged over the tail of the plate. The lower cut-01f plate L is provided with similar cut-off openings Z and valves N. These valves may be of any desirable construction and are each provided with a suitable fastening device for holding the valve open or closed. As shown in the drawings, Figs. 4:, 5, and 6, the stem 0 of each valve extends through one of the side boards of the shaking-shoe and is provided on the outer side of the same with a segment and handle n for shifting the valve. A lug q is secured to the shoe and carries aclamping-screw q,which engages the segment for holding the valve in the desired position.
In the operation of the machine the mixture of hulled and unhulled grain which is fed from the feed-hopper upon the head of the upper screen is first separated by the front portion a of the upper screen, through which only hulled grain passes by reason of the smaller size of the hulled kernels. When the material reaches the rear portion 6 of the upper screen it is althe material which passes through the screen in rear of this open valve is cut off from the clear-hulled grain and sent to the tailend of the cut-01f plate I, whence the material is conducted by the conveyer-plate K to the head of the lower screen E. In Fig. 1 the first cut-off valve M is shown open for this purpose, while the other valves are closed. The hulled grain which passes through the open valve of the cut-off plate I falls upon the conveyer-plate J, which latter also receives the hulled grain which passes through the front portion 6 of the upper screen and falls upon the front conveyer-plate F. The hulled grain from the upper screen passes from the conveyer-plate J to the spout Gr and lower conveyer-plate H and is discharged through the delivery-spout 72,. The mixture of hulled and unhulled kernels which is delivered by the conveyer-plate K upon the head of the lower screen E is further separated by this screen, and as the lower cutoff plate L is also provided with cut-off valves this plate can be open at the point where paddy begins to pass through the lower screen, so
that the mixed material is cutoff at that point.
and delivered over the tail end of this cut-off plate, while the clear-hulled grain passing through the front portion of the lower screen escapes through the open valve and joins the clear-hulled grain from the upper screen flowing over the lower conveyer-plate H.
The mixture of hulled and unhulled kernels can be delivered from the tail end of the lower cut-off plate L to a receptacle Z, which also receives the paddy which tails off from the upper and lower screens, or can be disposed of in any other suitable way.
The cut-off plates I and L are preferably constructed of wooden boards 1 and a sheetmetal covering 8, and the cut-off valves are similarly composed of boards r and a sheetmetal covering 8, Figs. 4 and 6. The sheetmetal coverings of the plate projects rearwardly beyond the front edge of the cut-off opening, as shown at and is set back from the rear edge of the opening, as shown at 8 The sheet-metal covering 8 of the valve is set back at the front edge of the valve and projects at the rear edge of the valve to fit against the edges of the sheet-metal covering on the plate, so that when the valve is closed lapping joints are formed by the sheet-metal coverings of the plate and valves, whereby the joints between the boards of the valve and plate are closed. The lap-joints also serve to hold the valves snugly in line with the plate when closed, so that the upper surface of the plate is smooth and presents no obstruction to the flow of the grain.
I claim as my invention 1. The combination of a shaking-shoe, upper and lower rearwardly-inclined screens arranged therein, a rearwardly-inclined cut-off plate arranged underneath the upper screen and provided with one or more cut-offs which can be opened or closed at will, a conductor for conveying the cut-ofi' material from the tail end of said cut-ofi' plate to the head of the lower screen, a rearwardly-inclined cutoll' plate arranged underneath the lower screen and provided with one or more cut-offs which can be opened or closed at will, and conductors for the clear separated material arranged underneath said cut-off plates, substantially as set forth.
2. The combination of a shaking-shoe, an upper rearwardly-inclined screen arranged in the same, a rearwardly-inclined cut-ofi' plate arranged underneath the rear portion of said screen and provided with a cut-off which can be opened or closed at will, a rearwardly-inclined conveyor-plate for the clear separated material arranged underneath the front portion of the upper screen, a forwardly-inclined conveyer-plate for the clear separated material arranged underneath said cut-ofi' plate, a
rearwardly-inclined lower screen arranged in the rear portion of said shoe, a forwardly-inclined conveyer-plate conducting the cut-off material from the tail of said cut-ofi' plate to the head of the lower screen, a lower rearwardly-inclined cut-ofl' plate arranged underneath the lower screen and provided with a cut-off which can be opened or closed at will, a conveyer-plate for the clear separated material arranged underneath said lower cut-ofi' plate, and a spout arranged in front of the lower screen for conducting the clear separated material from the upper screen to the conveyer-plate below the lower screen, substantially as set forth.
