(under subclass 293) Subject matter wherein the jaws of said
work-gripping instrumentality are specifically modified for the purpose of temporarily deflecting or springing work from its initial shape while it is held in said jaws during an operation of the class type.
(1) Note. This type of clamp is employed to counteract, forestall, or prevent possible undesired deformation of untreated portions of the work, such as may occur in flanging the periphery of a circular plate in a step-by-step manner.
(2) Note. The deflection of distortion effected by the clamp is only temporary (i.e., within the elastic limit of the work material), see (2) Note under subclass 300 above.
