Abstract
A centrifugal clutch has an axially extending hub formed with a central bore for receiving and mounting the clutch on a drive shaft. A drive flange is attached to the hub for rotation with the hub when it is rotated by the drive shaft. A pair of clutch shoes is pivotally mounted on the drive flange in an end-to-end relationship with respect to each other by a pair of pivot pins. Extension springs bias the swinging ends of the clutch shoes toward retracted position. The clutch shoes are adapted to move outwardly under the influence of centrifugal force and overcome the biasing effect of the springs to drivingly engage a concentrically mounted clutch housing. Each of the clutch shoes has an arcuate-shaped web and an outer shoe table with a strip of frictional material being mounted on the table. An inwardly extending projection is formed integrally as a part of each shoe web adjacent the respective pivot pin and is adapted to abut against the hub when the shoes are in retracted position to prevent further inward movement of the shoes due to the biasing of the springs.
