An upper bearing proportioning arrangement applies a low percentage of a large proportion of the total oil flow to the upper bearing. Together these features assure a high degree of motor cooling without overlubricating the bearings.

Abstract: This invention relates to an improved pillow block characterized by a cast body containing a main bore for housing an antifriction bearing and cast bolt-receiving slots for mounting same and for attaching endplates thereto that do away with the need for drilled and tapped holes. The endplates are cut from common sheet materials and gang-drilled to provide the apertures that accept the bolts used to assemble same onto the opposite faces of the body with an O-ring therebetween to establish a fluid-tight seal. In like manner, a hole cutter is used to cut rather than drill a central hole for passing the rotating element to be journalled in the bearing.

Abstract: The wheel mounting of the present invention is designed particularly for use in cable car structures at intersecting street corners, that is, where the cable is carried around a curve. The structure comprises, briefly, a pair of normally vertically spaced horizontally extending supporting pleats and a vertical shaft fixed to the plates and which journals a cable supporting wheel, the later being thus normally mounted to rotate in a horizontal plane. The structure is intended for mounting in below ground surface at the elevation of and to support the car driving cable. Of particular importance is the provision in mounting of a bearing in the wheel hub surrounding the shaft and which has an outer race at the hub wall of the wheel and an inner race at the shaft, the two races being rigidly clamped to the hub and shaft so as to positively confine the forces imposed on the bearing to those forces which the bearing is designed to withstand without undue heating, wear or deterioration.
