[Classes 12 (i) and 12 (ii)] In a spherical bearing, the outer bearing ring 3 is of greater axial length than the coacting spherical surface 2 of the inner bearing ring 1 so as to support frictionally on its spherical surface thrust flanges 4, 5 which slidingly engage the plane end faces of the ring 1. This arrangement obviates a high load at the edges of the journal and brings about an even distribution of both radial and thrust loads. The flanges 4, 5 are supported on spaced zones, the recesses 8 between which facilitate lubrication. The ring 1 is of T-section, lubricant being thrown centrifugally from the groove 9 through passages 10 to the bearing surfaces. The tilting property of the flanges 4, 5 facilitates the formation of wedge-shaped oil films at the thrust surfaces.

Abstract: 283,999. Stone & Co., Ltd., J., (Darker, A. H.J. Oct. 18, 1926. Shafts; securing pulleys on shafts.-To enable a pulley or a series of pulleys with bores of uniform diameter to be secured truly concentrically with the shaft bearings upon shafts which may be out of truth or which may differ in diameter, metal strips b are secured by spot welding or other means to the shaft a and are turned down to provide a properly situated series of surfaces fitting the pulley hub. The pulley may be keyed to the shaft or, as shown, may be frictionally tightened thereon. Axial movement of the pulley on the strips may be prevented by forming shoulders on the strip ends or by forming channels g, Fig. 4, in the strips for engagement by the beads h of rivets employed in the pulley construction. By substituting recesses g<1> for the channels g, relative rotary motion is also inhibited. In a further modification, Fig. 5, plates j secured within the pulley hub engage between the strips b to prevent relative rotation.
