DEFINITION

Classification: 72/317

With plural selectively usable clamps (e.g., tube flarer):

(under subclass 316) Subject matter comprising two or more instrumentalities each capable of gripping work, only one of which is employed at any given time to clamp work during an operation of the class type.

(1) Note. Typical of this subclass is a tube-flaring tool having clamping jaws which include a plurality of semicircular mating recesses of varying sizes along the inner facing edges of the jaws, the selected pair of mating recesses constituting a clamp for accommodating a tube to be flared.

(2) Note. Not all tube flarers employ nondeforming work clamps. If work is deformed upon tightening of the jaws, the combination may be placeable in subclass 356 or 357 if a closed die is involved, otherwise in subclasses 394+ as an opposed face tool complex*.
