ABSTRACT:
The disclosure relates to an adjustable V belt pulley which is readily adjustable so as to vary the pitched diameter of the pulley at which a conventional V belt operates between outwardly diverging annular sheave faces of the adjustable pulley. The disclosure also relating to a novel means including a compressible bushing adapted to surround a shaft and lock the adjustable pulley of the invention on the shaft when the relatively adjustable sheave members are clamped together by bolts which extend therethrough generally axially parallel to the axis of shaft receiving openings in the hubs of the sheave members. Additionally, the disclosure relates to the foregoing structures and additionally to spacer washers which may be either placed between the sheave members or on the outer sides thereof so as to vary the spaced relation of the outwardly diverging annular faces of the sheave members in order to vary the pitched diameter at which a standard V belt will run between the said annular faces of the sheave members. The disclosure also relating to modifications of the sheave members and particularly with relation to the fabrication of the sheave members of sheet metal by various methods such as pressing or spinning operations.
