DEFINITION

Classification: 72/404

BY PLURAL TOOL COUPLES:

(under the class definition) Apparatus, not provided for in a preceding subclass, and comprising two or more tool-couples.

(1) Note. The apparatus may constitute plural devices, each of which is complete, per se, (e.g., two machines side by side or in tandem), or the devices may have parts in common (e.g., the arrangement of two hammers alternately engaging work lying on an anvil), but in any case the combination should fall short of constituting a tool-complex* for subclasses 381 and 394.

(2) Note. A patent to a multi-tool station or progressive punch press may be placeable as an original copy in this subclass, whether it treats discrete blanks or a continuous strip of stock material. If integral work material extends under a plurality of tools which do not have identical motions but which engage the material simultaneously, the combination may be placeable as a tool-complex* in the above noted subclasses.

(3) Note. This is the residual locus for the combination of two or more metal-deforming devices. To complete the search on such combinations, see all preceding subclasses which refer to plural operations or to different types of metal deformation; in the preceding subclasses, one operation or type of apparatus will be of a specified description (e.g., subclass 348, cup or shell drawing with additional metal deformation).

SEE OR SEARCH THIS CLASS, SUBCLASS:

68, for the combination of rotating or gyrating tool apparatus with other metal-deforming apparatus.

130, 137, 152, 161, 168, and 177, for a combined operation including metal deformation by deflecting bodily moving work. 187, 221, 256, 278+, 306+, 348+, 356, and 384, for a combined operation including one specified type. (See (3) Note Above.)
