Abstract: A bearing arrangement for the support of a swinging body. The bearing arrangement in which the swinging body is provided with a rotatable bearing shaft. The bearing shaft is supported in the bearing assemblies having deformable bearing bodies. The bearing bodies are provided with external conical surfaces that engage internal conical surfaces of associated bearing shells.

Abstract: A combine conveyor arrangement for transferring clean grain from a cleaning shoe to a grain tank above the shoe comprises two drivably connected screw conveyor legs whose axes lie in a common vertical plane. A unitary housing at their junction provides bearing support for the respective screw conveyors, an enclosure for a pair of bevel gears transmitting power between the two, and a transfer passage for receiving the discharged material from the first leg and conducting it to the second leg. The first leg is substantially horizontal and the second is inclined upwardly and inwardly so that the included angle between the two conveyor legs is substantially less than ninety-degrees, and the transfer passage is offset inwardly and upwardly from the intersection of the conveyor axes.

Abstract: In an axial flow rotary separator, a threshing or separating grate, surrounding and generally concentric with a rotor is made up of two generally semi-cylindrical halves. An interconnected adjusting linkage arrangement is connected to and supports both halves adjacent their axially extending free edges. Operation of the linkage moves both grate halves simultaneously and equally. Each grate halve comprises two axially extending grate panels connected to each other so as to permit pivoting about an axis close to their inner surfaces and parallel to the rotor axis.

Abstract: The feeding system for an axial flow rotary combine in which the separator is disposed generally fore-and-aft includes a dual auger feeder house in which a pair of side-by-side upwardly and rearwardly inclined augers are driven in such directions that a major part of the crop material handled is conveyed in a concentrated high speed stream between the augers and delivered in undershot fashion to be engaged by a separator infeed rotor for transfer downstream to a coaxial threshing section. In the preferred embodiment the infeed rotor and its housing are generally frusto-conical in form, the rotor including a frusto-conical core carrying four equally spaced axially extending tapered feed bars, each bar having a ramp-like cross section, with the rotationally leading edge of the ramp radially closer to the rotor axis than the trailing edge.
