DEFINITION

Classification: 15/300.1

With air blast or suction:

(under subclass 3) Subject matter having claimed structure functioning to contact a work piece or work surface with a draft of air, steam, or equivalent gaseous fluid for the purpose of dislodging or removing unwanted foreign material therefrom.

(1) Note. In this and the indented subclasses, the term "air" is used generically to designate air, steam, or equivalent gaseous fluid.

(2) Note. The draft of air need not be the primary cleaning or dislodging means; this and the indented subclasses include devices wherein means are provided for brushing, beating, shaking, or otherwise manipulating the work to dislodge the foreign material and wherein the draft of air acts to convey away the material so dislodged, or any portion thereof, provided only that the draft of air must contact the work.

(3) Note. Where an air draft is used as a means to feed material to or discharge material from an art device, the patent is in general classified with the device, even though a vacuum pickup is used on an ambulatory device; except that a gas separator of the Class 96 type is classified in this class (15) if claimed in combination with means for applying an air-draft to a workpiece or work surface.

(4) Note. Where an air draft functions to perfect the operation of an art device, the patent is classified with the art device.

SEE OR SEARCH THIS CLASS, SUBCLASS:

21.1, through 103.5, for a device wherein a mechanical work contactor of the character provided for there delivers the foreign material to a place of collection not on the work surface and from which place an air draft is utilized to convey the material.

SEE OR SEARCH CLASS 30, Cutlery, especially

124+, for a cutlery device combined with air blast or suction means for collecting or disposing of the severed material, and see (4) Note above.

34, Drying and Gas or Vapor Contact With Solids, for gas or vapor contact for drying, and see (3) Note in the main class definition of Class 34 for a further statement of the line.

43, Fishing, Trapping, and Vermin Destroying,

139+, and 141 for air-blast or suction devices disclosed solely for trapping or destroying insects.

118, Coating Apparatus,

21, and 63 for an apparatus having gas blast means to remove or spread coating material.

131, Tobacco,

244, for an apparatus for cleaning a smoking device by the use of an air draft.

162, Paper Making and Fiber Liberation,

363+, for a suction device for use in a paper making machine. 173, Tool Driving or Impacting,

57+, for a means to drive or impact a tool or the like having a work cleansing modification, such as a means to supply air or other fluid to the tool or work surface, or a suction source.

175, Boring or Penetrating the Earth,

209+, for a means engaging a bore entrance for receiving or directing cuttings moved by an air blast or suction combined with an earth boring means. The mere recitation in a claim of means on said bore entrance engaging means for supporting or accommodating an earth boring or penetrating tool or tool shaft is sufficient for classification in Class 175.

198, Conveyors: Power-Driven,

495, for a conveyor having installed as part of its structure a means for applying a cleaning fluid to a component of the conveyor.

239, Fluid Sprinkling, Spraying, and Diffusing, The line is as follows: This and the indented subclasses in Class 15 take discharge or suction nozzles for air, steam or equivalent gaseous fluid which are disclosed solely for cleaning and which are combined with claimed means for (1) handling or supporting the work, or (2) supporting or spacing the nozzle from the work, or combined with claimed cleaning devices such as brushes, scrapers, wipers, beaters, shotters or the like. Class 239 takes nozzle (discharge or suction) structures, per se, of the character indicated in

525+, 548+, 569+, 586, and 589+ in that class even though disclosed solely for cleaning by the use of gaseous fluids, except that, as stated above, Class 15 takes a nozzle device

which functions to contact or to engage the work, such contact or engagement usually serving to promote or perfect the cleaning operation.

406, Conveyors: Fluid Current, for an apparatus for conveying material by a gaseous fluid including material pickup, not specialized for cleaning.

417, Pumps, appropriate subclasses, for the pump subcombination of an air blast or suction cleaner. This and the indented subclasses in Class 15 take an air or gas pump claimed in combination with a suction or a blast applying nozzle means, disclosed for cleaning, and also take a pump disclosed which functions to contact or engage the work to promote or perfect the cleaning operation.

418, Rotary Expansible Chamber Devices, for a rotary expansible chamber device, per se, and see the above note to Class 417. 604, Surgery,

313+, for means for removing an impurity from the skin by vacuum or suction.
