Abstract

A pulley system for an automatic washer wherein the automatic washer includes a wash basket rotatably disposed within a tub and a motor having a motor shaft for selectively rotating the wash basket about a horizontal axis. The pulley system is disposed between the motor and the basket for drivingly connecting the motor with the basket and includes a drive hub disposed external of the tub drivingly interconnected with the wash basket. A pulley having an inner surface slidably disposed about the outer diameter of the drive hub is provided such that the pulley may rotate a predetermined angular distance about the hub before drivingly engaging the drive hub for co-rotation. A trip arm is interconnected with the drive hub and the pulley and is adapted for selective partial extension beyond the outer periphery of the pulley in response to the direction of wash basket rotation. A belt is drivingly disposed about the motor shaft and the pulley for drivingly interconnecting the motor with the pulley.
