Abstract
Abstract An appliance supporting caster structure includes a caster assembly adjustably mounted on a frame portion of the appliance. The caster assembly includes a U-shaped body member having a caster wheel rotatably mounted thereon. A brake means for the caster wheel comprises a chock and operating means for mounting the chock on the appliance frame for movement between a position in which the chock blocks rolling movement of the wheel and an inoperative position. The operating means also includes a portion frictionally engaging the caster assembly body member for holding the chock in either of these positions.
