Abstract: A conveyor shaft seal for isolating a shaft bearing includes a resilient surrounding frame supporting a shaft embracing anti-friction sleeve. The innermost end of the sleeve within the conveyor is angled downwardly toward the conveyor wall whereby, during operation, the ingress of the material of the conveyor at the interface between shaft and sleeve is minimized, to extend the life of the bearing.

Abstract: A planetary speed reducer includes a drive roller having a drive surface, a stator having a concentric drive surface, the respective drive surfaces defining an annular space therebetween. A plurality of rotatable planet rollers have peripheral portion in frictional driving connection with the said drive surfaces of the roller and stator. An output shaft is connected to an assembly which carries the planet rollers.

Abstract: A speed reduction drive is comprised of a chain carrying a plurality of rollers, the chain being operatively connected to an output shaft via a sprocket or the like. The rollers of the chain progressively pass between a rotating drive pinion and a stator surface whereby the chain is driven at a linear speed which is a function of the diameter of the drive pinion and the arcuate surface of the stator, the speed of the chain being reduced by differential drive effects.

Abstract: A rotary seal comprises an elastomeric sleeve adapted to be mounted on a shaft, a pair of washers encompassing the ends of the sleeve, wear plates engaged against the anti-friction washers, and a compression device for urging the washers toward each other axially to fore-shorten the sleeve and define between the sleeve and washers a torque driving connection, said washers being formed of anti-friction polymeric material and said wear plates being formed of metal or vice versa.

Abstract: A junction for torque transmittingly connecting adjacent sections of an auger type conveyor eliminates the need for hanger bearings between conveyor sections. The junction includes a cylindrical sleeve having an external helix inclined to force conveyed material in an upstream direction in the area between the sleeve and trough and thus exert a lifting force on the junction. The sleeve includes a flow passage in registry with the helix and may include internal auger segments which mate with the conveyor sections.

Abstract: The present invention is directed to a dead shaft bearing device for an auger type conveyor. The device is characterized in that the bearing components are readily replaceable without the necessity for disassembling the conveyor, and provide a leakproof assembly barring ingress of pulverulent material to the bearing surfaces and escape of pulverulent materials through the wall of the conveyor trough.

Abstract: This invention relates to an improved hanger bearing construction for auger conveyors and is directed more particularly to a sealed hanger bearing having improved service life. The device is characterized by the provision of frictionally driven wiper means which rotate with the shaft and prevent the ingress of contaminants into the interior of the bearing structure with consequent premature compromise of the bearing.

Abstract: The present invention is directed to a jam resistant shredder-feed device for advancing and comminuting elongate materials, such as copper wire scrap, plastic mold runners and the like. In accordance with the invention, an auger assembly is rotated within a cylindrical housing, the auger assembly advancing the materials to be comminuted toward a stationary knife or breaker. The device is characterized by the employment of one or more idler auger sections adjacent the stationary knife, the upstream and downstream ends of the idler section or sections themselves defining knives, as does the downstream end of the feed auger, the respective knife portions being preferably spaced apart in a longitudinal direction by distances slightly greater than the average thickness of materials to be processed.

Abstract: The present invention relates to a grinding mill system including a ball mill, rod mill, or the like, the system being characterized by an improved, simple and highly effective proportioning feed device for automatically optimizing through-put under any of a series of differing operating conditions. The system automatically proportions raw material to be ground with partially ground but oversize materials in an efficient manner without the use of complex and expensive electronic and like sensing devices and circuits.

Abstract: The present invention is directed to a self-compensating rotary seal member adapted to be used where a vertically directed shaft passes through an aperture in a casing or the like to prevent the passage through the aperture and consequent contamination of bearings, etc. disposed to the opposite side of (e.g. below) the casing. The seal assembly is characterized by the provision of a well member having upstanding cylindrical side walls and a generally horizontal floor portion formed of material having a low coefficient of friction, the shaft having keyed thereto a high density thrust washer which is gravitationally maintained in contact with the floor portion, the thrust washer being driven with the shaft.

Abstract: The present invention relates to a self-compensating rotary seal member such as is used in low pressure applications, i.e. where a drive shaft extends through a container wall. The seal member is characterized by an elastomeric collar member mounted on the drive shaft within a housing, the ends of the collar being in frictional driving connection with a spaced pair of thrust washers, the washers in turn being yieldingly pressed against wear plates formed of material having a low coefficient of friction. Sealing is effected in a direction axially of the shaft by the interfit of the collar about the shaft, and in the direction normal to the axis by the frictional and rotary engagement of the thrust washers against portions of the wear plate or plates surrounding the shaft and disposed at the ends of the housing.
