Abstract: A pipeline padding vehicle for supplying earth of a fine consistency to cover and pad a pipeline disposed in a trench has a longitudinal conveyor, a vibrating screen to receive earth from the conveyor, and a padding material discharge conveyor beneath the screen to receive material therefrom mounted to pivot about a vertical axis from a position in which it is longitudinally aligned with the vehicle frame to a position transverse of the frame. A sub-frame mounts the vibrating screen and discharge conveyor on the vehicle for fore and aft swinging movement about a generally horizontal axis transverse to the longitudinal extent of the vehicle frame.

Abstract: This inventions's method separates from excavated materials (2) fine constituents (3), preferably topsoil, and coarse constituents (4), preferably stones, roots or root crops. The materials to be excavated (2) are excavated by an excavating and separating bucket (11), of grid structure, which is subjected to separating movements causing the fine constituents (3) to escape from the excavating and separating bucket (11) through apertures provided for that purpose. To produce shock-free separating movements the excavating and separating bucket (11) is rotated continuously through one or preferably a plurality of revolutions in the same direction of rotation (R).A simple apparatus for carrying the method of the invention into effect is described. The excavating and separating bucket (11) is a unit (5) connected to an excavating and elevating assembly (8) on a vehicle (9).

Abstract: A seed cleaning device includes a frame and first and second screened grids, each of which is pivotably mounted to the frame. Two crankshafts are mounted to the frame and are coupled to one another to remain 180 degrees out of phase with respect to one another. Each of the crankshafts causes a respective one of the screened grids to oscillate, such that the oscillation of the first screened grid is out of phase with the oscillation of the second screened grid.

Abstract: A device for loading granular material containing some foreign matter into a container, such as a railroad car, has upper and lower chutes arranged in parallel. The upper chute has a bottom screen for allowing the foreign matter to fall through to the lower chute. The grain flow remaining on the upper chute is discharged down the center of the car and fills toward the sides, while the foreign matter falling to the lower chute is distributed evenly by sidewardly extending wings out toward the sides and in towards the center of the car. By the operation of the device, the foreign matter carried in the grain is evenly distributed and mixed throughout the car, and the tendency of the foreign matter to concentrate along the center under the hatchway of the car is prevented. A sample of the grain taken from the hatchway of the car thereby contains a truer percentage of foreign matter to grain than would occur by conventional loading devices.

Abstract: An arrangement for piling a bulky material of different grain sizes has one central and two lateral passages, a guiding element located upstream of the passages and arranged to guide a flow of a bulky material toward the lateral passages, and grate elements located between the guiding element and a respective one of the passages and arranged so that the fine portion of the material passes through each of the grate elements into a respective one of the lateral passages, whereas the coarse grain portion of the material is guided over the grate elements so as to pass into the central passage.

Abstract: Apparatus for recovering silver from spent photographic solutions comprises a tray with a number of non-reactive filter elements having successively smaller porosity through which the spent solutions can be passed. Each successive filter element prevents silver particles of progressively smaller sizes suspended in the liquid from passig therethrough. The filters are stacked in a horizontal position within the tray and a tray cover sits on top of the tray, the cover having an opening into which the developing solutions can be poured. The tray includes a drainage port which allows liquid passing through the filters to drain out of the tray.

Abstract: A garden sieve for mounting on a wheelbarrow has a frame and a stand adapted for detachable connection by means of selectively engageable projections and recesses, with the frame in any one of a series of positions whereby the extension and/or angular position of the stand relative to the frame is adjustable. In the preferred embodiment the stand has two arms, the free ends of which engage opposite sides of the frame near one end thereof and the other end of the frame carries clips intended in use, to fit over an edge of the wheelbarrow.

Abstract: A grading plant with self-cleaning screen for lump materials, the screen (3) being pivotally mounted to a carriage (2) displaceable on horizontal beams (1). The screen has wheels (5) guided in tracks in the beams. Each track has a horizontal portion (11) and a curved downwards directed portion (12). The screen is in a position for discharging when the wheels (5) are in the lowermost part of the downwards directed portion. The motion of the screen (3) is exerted by a moving device consisting of a wire arrangement (7) for the backwards directed movement and a return spring (20) for the return motion, or a double-acting hydraulic cylinder (18) moving the carriage in both directions.

Abstract: A portable loam screening apparatus includes a nearly-square, sloping shaker screen supported by a box-like frame. The frame has a tall end and a short end joined by two sides. Funneling surfaces directed toward the screen are provided along the upper edges of the tall end and the sides. A mixture of coarse material and finer material is dumped onto the shaker screen from the shovel of an excavating vehicle. The coarse material falls from the lower end of the shaker screen outside of the frame, and the finer material passes through the shaker screen to within the box-like frame. The separated finer material is directed to an outfeed conveyer by a hopper or feed conveyor within the frame. The outfeed conveyor extends through one of the sides. A set of wheels mounted to one side of the frame is movable relative to the frame from an operative position for transporting the apparatus to an inoperative position for resting the frame flush on the ground.

Abstract: Relatively fine materials are separated from bulky materials by a two-tier screen assembly mounted on springs and shaken by an off balance drive. The screen assembly spans the space between two parallel plates which are joined by staggered crossbeams. An upper screen is supported by longitudinal bars which rest across upper crossbeams, and two lower screens rest on lower crossbeams. The crossbeams are joined by a longitudinal center plate. In use, the forces of heavy weights tending to bend a given crossbeam are transmitted through the center plate to the joined crossbeams to reduce the strain on the single beam.

Abstract: A cleaner for removing waste particles from grain and similar agricultural products. The cleaner comprises a pair of concentric drums adapted to be rotated in unison and having perforated outer surfaces for separating out waste particles. The inner drum has a plurality of sections of decreasing diameter for deterring the flow of the grain therethrough while separating out the waste particles.

Abstract: A gravel processing system, preferably of the portable type, utilizing a plurality of screens and conveyors wherein the particle sizes of the finished product may be accurately regulated, and readily varied. Two screen boxes are mounted upon a frame, each box including a plurality of screens which are charged at their inner ends by a top-loading hopper having several outlets providing a versatility of screen charging. The vibrating screens discharge at their outer ends, and the conveyors located below the screens convey the fines from both screen boxes to a common discharge point. A chute and bypass system at the discharge end of one screen box permits the screen discharge to be selectively conveyed to one of several conveyors or chutes, for re-processing or re-crushing, and the apparatus of the system provides extraordinary versatility and particle size sorting and classification in a relatively concise apparatus.
