<p>The current wiper (1) has a current wiper shoe (10) attached to a pivoted oscillation arm (9), displaced between a working position and a rest position, in which it can be secured via a piston-cylinder unit (13). The piston rod (14) of the latter is coupled via a coupling element (17) with a latch lever (19) secured to the frame (2) of the current wiper and held in the rest position by a latch spring (21). The latch (28) of the latch lever is engaged by a release cylinder (29) for movement from the rest position against the latch spring bias, until the second end (18) of the coupling element passes a dead point, for movement of the oscillation arm for the current wiper shoe into engagement with the third rail via a main spring (11).</p> |
