DEFINITION

Classification: 15/301

(under subclass 300) Cleaning apparatus in which the apparatus as a whole, when completely assembled and operating as a cleaner, is nonmobile or fixed in position, or is installed in or attached to a structure for the cleaning thereof.

(1) Note. The air-draft applying means may itself be mobile during the cleaning operation, so long as the air-pump or supply remains fixed, and either or both the air-draft applying means and air pump or supply may be detachable when not cleaning.

(2) Note. In this and the indented subclasses are placed, for example, patents for vacuum cleaning systems installed in or on buildings, vehicles, or art devices or structures for the cleaning thereof and including only so much of the building, vehicle, or device as is necessary to the operation, support, or location of the cleaning apparatus, with respect to that portion of the building, vehicle, or device being cleaned.

(3) Note. The line with Class 122, Liquid Heaters and Vaporizers, is: Class 122 takes air or steam cleaners for boiler structure where any part of the boiler or furnace structure is modified to cooperate with the cleaner for the support or functioning thereof and such modification is

claimed. The same line is followed with Classes; 122, Liquid Heaters and Vaporizers; 165, Heat Exchange; 196, Mineral Oils: Apparatus; and 202, Distillation: Apparatus; 422, Chemical Apparatus and Process Disinfecting, Deodorizing, Preserving, or Sterilizing. This and the indented subclasses in Class 15 take soot blowers when disclosed as being the type usually permanently connected with a boiler or other heat exchanger but claiming no modification of the boiler or heat exchanger.

(4) Note. Mere ventilating hoods or off-takes are not here included but in general are classified with the art device with which associated; see Search Classes below.

SEE OR SEARCH THIS CLASS, SUBCLASS: 336, for convertible cleaners, mostly of the "Air-Way" type, having racks, brackets, or the like for supporting the cleaner while in use for off-floor cleaning.
