ABSTRACT:
A blower/dryer assembly of the type comprising an electric motor, an impeller attached to the output shaft of the motor to be driven thereby, a molded plastic toroidal housing surrounding the impeller and a discharge nozzle attached to the impeller housing. The housing is attached to an adapter plate on the base plate of the motor by means of threaded fasteners arranged in a circular pattern which pass through slotted openings in the adapter plate and into reinforcement plates on the inside surface of the impeller housing. The slotted openings permit the angular relationship between the impeller housing and the adapter plate to be non-incrementally varied over a substantial angular range. The impeller housing is formed of a large diameter clearance opening in the surface immediately adjacent the motor end plate so as to receive therein the large diameter adapter plate. The opening is of such size as to permit the impeller housing to be removed from the adapter plate by passing the impeller through the opening thereby to eliminate the necessity of disassembling the impeller from the motor shaft for housing removal. The impeller housing and the nozzles are formed as separate components adjoined by mating flanges so as to facilitate nozzle replacement and/or exchange.
