ABSTRACT:
A centrifugal clutch has a pair of clutch shoes pivotally mounted on a pivot collar for outward movement under the influence of centrifugal force to drivingly engage a concentrically mounted clutch housing. Extension springs bias the swinging ends of the clutch shoes toward retracted position. The pivot collar has a hollow cylindrical sleeve with a pair of nearly cylindrical projections mounted diagonally opposite of each other on the external surface of the sleeve. The cylindrical projections are similar to and are located parallel with each other and to the axis of the sleeve and have cylindrical circumferences greater than 180.degree. and less than 360.degree.. The imaginary circumferences of the outer surfaces of the projections lie in an overlapping or abutting relationship with the imaginary circumference of the outer surface of the sleeve. A discontinuous opening is formed on one end of each clutch shoe adjacent the inner edges thereof and have a shape and size complementary to the outer cylindrical surfaces of the collar projections. The collar projections are telescopically inserted within the clutch shoe openings to pivotally mount the clutch shoes on the pivot collar. The pivot collar is mounted on a drive shaft for rotation with the shaft. The clutch shoes each include a pair of similar half-shoe sections and an intervening spacer segment sandwiched therebetween. The extension springs extend between adjacent hook ends formed on the shoe spacers to bias the shoes toward retracted position.
