DEFINITION

Classification: 266/114

(under the class definition) Device wherein an apparatus is provided for treating either a metallic article or a metal bearing ore which is in a hardened form by applying a liquid thereto.

(1) Note. The term "solid" as used herein includes within its purview granular or pulverulent material which is composed of discrete solid particles.

SEE OR SEARCH CLASS

15, Brushing, Scrubbing, and General Cleaning, for cleaning and liquid contact apparatus of the type stated below as going to Class 134, where a brush, wiper, scraper, suction, or gas blast cleaning means or a squeegee is part of the combination.

118, Coating Apparatus, appropriate subclasses, for apparatus for coating metal work including apparatus for performing a coating process in which a chemical reaction occurs.

134, Cleaning and Liquid Contact With Solids, for solid metal cleaning and pickling processes, per se, i.e., not combined with any other solid-metal treating operations. This class also has apparatus for cleaning and pickling solid metal combined with such means for handling or operating upon the solid metal as are necessary for the cleaning or pickling operations. Class 266 has apparatus for heating solid metal by contact with molten solids for heat treating the solid metal, Class 134 having no apparatus disclosed for this purpose. Class 134 also has apparatus for contacting solid metals with liquid for other purposes (as quenching) where the means claimed pertain to the applying of the liquids and

only such means for manipulating or handling of the solid metal as are required to present the metal to, move or support it during, and/or remove it from the means that applies the liquids. Apparatus involving, in addition to the cleaning or liquid-contact means, means for the purpose of preventing warping, straightening, forming by any manufacturing means (note stretching below) or separate heating, is considered to be beyond the scope of Class 134 and is in Class 266. Separating material from solid metal by heating only (as distinguished from the application of liquids which liquids may be heated) has not been placed in Class 134, but remains in Class 266 or other appropriate heating class. In the case of strip or strand material, Class 134 has apparatus which involve means for uncoiling, coiling, or temporarily distorting the material to feed and/or discharge such material during the cleaning or liquid contact operation, and also has means to stitch (as by welding, for example) or otherwise fasten one piece to another to make the operation continuous with or without means to subsequently cut the material into sections. Further, apparatus for contacting only certain areas of a metal body with a liquid to selectively harden the body will be found in this class (266). 148, Metal Treatment, appropriate subclasses for processes of quenching or utilizing liquid contact with metal to modify or maintain the internal physical structure (i.e., microstructure) or chemical property of metal.
