WITH MEANS TO ACTUATE BOTH ELEMENTS OF TOOL COUPLE:
(under the class definition) Device comprising two coacting tools* and power-transmitting linkage which is effective to move said tools in the performance of a deforming operation.
(1) Note. The tool-couple found in this and indented subclasses is generally of the opposed-face type. Subclass 407 contains, for example, disclosures of fluid-pressure actuated riveting machines; and subclasses 409.01+ contain plier-type devices.
(2) Note. Many examples of a metal- deforming tool-couple with both tools actuated, will be found in preceding subclasses directed to specific types of apparatus.
