Definition

This is the generic class of metal working or shaping. It comprises processes, tools, machines, and apparatus not classifiable in the specific classes relating to the manufacture of articles from metal. It also includes means which comprise a plurality of operations which separately might be classified in the specific classes, but which by their joinder include more than is covered by the definitions of such specific classes.

This class has been made the generic class for the following subject matter, regardless of the composition of the blank, stock material, or article recited or worked upon: (a) process of electric condenser making; (b) a burnishing process; (c) a process of manufacture; (d) apparatus used to assemble or disassemble. See Subclass References to the Current Class, below, for specific subclass references.

Notes

(1) Note. Patents claiming both an article or product and a process of manufacturing that article or product which process is classifiable in this class are classified in a suitable article or product class and cross referenced to the appropriate subclass of this class. (2) Note. Historically, the term "metal working" has included assembling. Therefore assembling is included within the scope of paragraph I, above, even though no metal parts are being assembled. (3) Note. While this is the generic mechanical manufacturing class, it is noted that manufacturing by chemistry, electrochemistry, or the related arts is provided for in the chemical classes. See the classes listed on pages I-6 and I-7 in the front of the Manual of Classification under "I. Chemical and Related Arts". Also see the Search Notes below (4) Note. The relation of other mechanical manufacturing classes to Class 29 is detailed on pages I-14 through I-16 in the front of the Manual of Classification under "III. Mechanical Manufacturing and Machine Element Arts, Manufacturing (Metal Working)". Also see the Search Notes below. (5) Note. Measuring, testing, recording and conveying, per se, are not considered "manufacturing" operations for this class.
