DEFINITION

Classification: 29/243.526

Having rotary drive mechanism:

(under subclass 243.521) Device including provision to move one tool with respect to the other to effect the deforming action, which provision turns more than 360 degrees.

(1) Note. The "drive" of this subclass must be mechanically connected to one of the tools, e.g., a rotary electric motor that drives a tool via a gear box is included herein even though the final drive may not turn more than 360 degrees, whereas a rotary electric motor that drives a pump which transmits fluid to drive one of the tools is excluded.
