101 | RELEASABLE ELECTRODE OR ROD GRIPPER TYPE: |
This subclass is indented under the class definition. Subject matter provided with a clutch mechanism interposed
between the motive power mechanism and the electrode, the clutch gripping
the electrode and/or the electrode holder rod during one
direction of motion of the motive power means, thereby applying motive
power to the electrode for moving the electrode in one direction,
and releasing the electrode and/or the electrode holder
from connection with the motive power means when the motive power
means begins to move in the opposite direction so that the electrode
is free to move in such other direction without regard to the amount
of motion of the motive power means.
