ABSTRACT:
A temperature responsive clutch has a first arcuate inward facing clutch member, which can be a housing, secured to a rotating shaft. A second arcuate outward facing clutch member is mounted on the shaft radially inward from the first member and rotates independent of the first member. At least a portion of the second clutch member is adapted to move into and out of engagement with the first member. In the engaged position, the first and second members rotate in unison to rotate a fan attached to the second member. A temperature responsive device, such as a wax pill motor, is located so air passes thereover. The temperature responsive device will move a portion of one of said members radially into engagement with the other member when the temperature of the passing air signals that additional cooling is needed.
