DEFINITION

Classification: 15/3

(under the class definition) Apparatus having means for contacting a work surface or object with an air blast and/or suction or with a beater, brush, broom, scraper, eraser,

squeegee, wiper, shot or other nonabrasive type particulate or comminuted solid, or having means for shaking or vibrating the work, or any combination of the above, for the purpose of dislodging and/or removing unwanted foreign material therefrom, and the surface contact is accomplished by power and motion means other than or in addition to that which the apparatus would have if merely held or supported by the operator and manipulated or moved by him relative to the work.

(1) Note. Subcombination or elemental devices apparently restricted in utility to use with machines under the above definition may be placed in this group of subclasses, such, for example, as the "nozzle" of air blast and/or suction cleaners which are found in subclasses 322 and 415+.
