Abstract: A series of semi-circular cut-out portions are provided on the underside of an auger tube which are covered with blanks when the cleaning device is not in use, but which are covered with semi-circular sieves when it is desired to clean grain or the like being augered. The mesh of the screens is selected to suit the cleaning desired. A shroud encloses the sieves and an auxiliary auger is situated at the base of the shroud and is driven by the main auger drive. This auxiliary or return auger moves wheat seeds and the like which have passed through the sieve, to a discharge at the lower end of the shroud regardless of the angle of inclination of the main auger assembly. Reinforcing means are provided on the upper side of the main auger tube (tension) and upon the lower side thereof (compression) in order that distortion and/or damage will occur to the main auger tube particularly during transportation of the auger assembly from one place to another.

Abstract: In the opening and cleaning of fibrous materials apparatus is provided which includes a plurality of rotatable beaters within a housing, curved under grids beneath each rotatable beater, baffle plates above and between the beaters, a perforated screen positioned above and adjacent the beaters and a suction hood positioned over and embracing the whole upper surface of the perforated screen. The screen is inclined to the horizontal and the apparatus includes a suction duct extending across the lowermost edge for withdrawing air from an inlet slot along the opposite edge to create an air stream flowing over the whole surface of the screen such that dust and unusable fibres passing through the screen are carried away to a waste extraction duct.

Abstract: A gin for use with leafy herbs separates the leaves from the stems, seeds, and other debris. A rotary bristle brush is rotatably mounted in the lower end of a hopper to transfer the leaves from the hopper into a collection compartment. The collection compartment is attached to the lower end of the hopper and supports a concave grate meshing with the brush. On rotation of the brush, the leaves are forced through the grate and the stems, seeds, and debris are retainingly enmeshed within the brush bristles.

Abstract: The present invention relates to a separator commonly used in flour mills. The grain is crushed by rollers and fed to the present apparatus for separation of a coarse product from a fine product. A drum section has stationary hammers extending from one end and rotating hammer extending from the other end. The rotating hammers are attached to a plate turned by a motor with the rotating hammers moving through the stationary hammers. This causes the crushed grain to be sifted through a perforated screen with the fine product feeding through an outlet for the fine product. The coarse product accumulates and spills over an upper edge of the perforated screen to feed through an outlet for the coarse product. The screen or its position, may be changed to vary the discharge from the present apparatus.

Abstract: Apparatus for separating or classifying the contents of a flowing slurry comprising a descending flow surface having a low profile and associated therewith a relatively low head box, the latter of which is distinguished by a relatively restricted cross sectional area adjacent its top. The flow surface is characterized by screen sections successive of which differ in orientation and profile whereby to produce a compact structure having a high capacity for separation of liquid from a flowing slurry. The design of the head box is such to enable a fast and effective delivery of slurry in spite of the low head provided.

Abstract: Vacuum device moves seeds and debris from an orchard floor to a troughed screen where flexible rotating fingers vibrate screen which separates the seeds from the debris and rotating rigid fingers move debris to a point of discharge. An auger may also be provided beneath the screen for moving separated seeds and fines to a cleaner for removing fine particles from the separated seeds, if desired.

Abstract: Liquid manure from an open pit is swept into the tubular housing of a loader by an impeller that rotates adjacent the housing inlet in close proxmity to one stretch of the housing wall that is in concentric relationship with the impeller. Stones larger than a predetermined size are screened from the manure by an arcuate grid that overlies the impeller in concentricity therewith. Thus, instead of ricocheting wildly within the housing following their separation from the manure, the stones are guided smoothly around the impeller and back out the inlet opening.

Abstract: A method and separator for removing sugar crystals from a syrup. The syrup is continuously delivered to a space defined by an inner conical first perforated wall subjected to air pressure and an outer conical second perforated wall coaxial with the inner conical wall and subjected to a vacuum from outwardly of the space containing the syrup. The perforations subjected to a vacuum are restricted by projections on a plate that extend axially into corresponding perforations and are movable axially therein to maintain these perforations unobstructed by sugar crystals. Rotationally driven scrapers scrape the inner surfaces of the second perforated wall in synchronism with the projections extending into the perforations.
