Abstract: A method and a device for screening aggregates and/or soils with a screening deck, where each point of the screening deck revolves continuously in the same rotating direction along a circular path. This movement is effected by the fastening frame of the screening deck being bearing-mounted upon at least two eccentric shafts, where each eccentric shaft is in turn bearing-mounted on a device body with bearings, through the midpoints of which extends a rotation axis of the eccentric shaft. Additionally, a throw axis spaced from the rotation axis of the eccentric shaft extends through the midpoints of bearings present between each eccentric shaft and the fastening frame, so that when the device is in operation, the throw axis revolves around the rotation axis along a circular path continuously in the same direction. All mass forces of movable structural components have been balanced with respect to rotation axes.

Abstract: A vibrating screen aggregate separation device separates finer grained material from an aggregate material that may contain a wide variety of undesired materials. A mesh design associated with a vibrating screen contains perforations to allow smaller diameter material to pass through into a container that is situated below the screen. A suspension system is affixed between the container and the vibrating screen to allow a range of motion that is conducive to vibration of the screen, while at the same time, is supportive of the weight of the aggregate material that is to be screened. Vibration of the screen is effected by rotating an unbalanced rod along its longitudinal axis to induce vibrational energy to the screen and associated supporting structures.

Abstract: Apparatus for removing debris from a fluidized sand bed. One or more troughs extend radially from a vertical shaft. Associated with each trough is a perforated chute. The apparatus is placed into the fluidized bed of sand, and rotated. As the apparatus rotates, the perforated chute sifts, or separates, debris from the fluidized sand. That is, the fluidized sand flows through the perforations, but the debris does not. When the apparatus is removed from the fluidized bed, the debris tumbles down the chute, into the troughs, if it has not already done so, and is captured.

Abstract: A modular screening apparatus has four parallel shafts arranged in a single plane mounted to each module. The shafts extend between the sides of the machine frame and are driven by a motor and timing belts which connect the shafts directly or indirectly to the drive motor. Each shaft supports three beater bars which are equally spaced about the axis of the shaft. A screen bed defined by a perforated polyurethane plastic sheet overlies the plane containing the driven shafts. The sheet serves as a screen which is clamped at its upstream edge, the downstream end extending over a fixed bar and vertically downwardly, to suspend a weight. The sides of the screen abut adjustable side plates which are mounted to the machine frame and define the boundaries of the screen bed. The beater bars rotate on the shafts to strike the underside of the screen.

Abstract: A trommel separator includes a clutch mechanism that operates with a shaft mounted right angle gear reducer for direct drive of the drum and a flexible mount. The clutch mechanism has a clutch slip disk which is located between first and second disks. The first disk receives the torque from the shaft mounted gear reducer which is then transferred to the second disk, which is rigidly connected to a rotating drum, when the first and second disk are pulled together. A clutch regulating system, namely jam nuts and a spring coil, are connected to the first and second disks through shafts for pulling the first disk and the second disk together. The flexible mount has a mount which rests upon a pivot plate for rotating the mount around a vertical axis. A first and second plate is attached to the gear reducer and horizontally rotatable within the mount. Clips keep the mount from lifting off a frame and spacers prevent the clamping of the mount. Pads are also used to prevent wear of the clips.

Abstract: A rapid coupling for a supported, driven shaft is disclosed. The coupling includes a coupling sleeve which is axially slidable over a drive shaft but keyed to the drive shaft to ensure that the coupling sleeve rotates with the shaft. The coupling sleeve has a driven end which includes slots for engaging driven pins affixed to a driven shaft. The coupling sleeve slides over and supports the driven shaft in a coupled position. The coupling sleeve is held in the coupled position by a quick release pin received in a bore through the drive shaft. The advantage is a simple coupling that is easily manufactured, the coupling being serviceable in a very restricted space where the driven shaft must be uncoupled without axial movement of either shaft.
