.~.~ Telescoping motion related to relative axial rotation or oscillation
DEFINITION
Classification: 175/322
(under subclass 321) Apparatus in which the sections of shafting include means acting between the sections so that the collapsing motion is accompanied by relative motion of the sections about the axis of the shafting (e.g., axial rotation or axial oscillation).
(1) Note. The axial motion may be specifically described as either (1) causing the collapsing or telescoping or (2) being
caused by the collapsing or telescoping of the sections for classification in this subclass.
SEE OR SEARCH THIS CLASS, SUBCLASS:
298, for devices having a below ground hammer or impact device in which continuous unidirectional rotary motion of one telescoping member effects the impacting.
