DEFINITION

Classification: 29/243.523

Pneumatic- or fluid-actuated tool:

(under subclass 243.521) Device wherein one of the tools is urged to move with respect to the other to effect metal deformation by a flowable medium.

(1) Note. (1) Incompressible fluid, e.g., liquid; (2) compressible fluid, e.g., gas; or (3) a flowable solid, e.g., pelletized material might be used as the urging medium of this and the indented subclasses.

(2) Note. A device having a vacuum "driver", i.e., a piston moved by ambient air pressure, is included herein.

(3) Note. A device including an explosively actuated piston is included herein.
