  • Patent number: 4481963
    Abstract: In an apparatus for conveying dripping electrodes, a drop collector having a plurality of parallel gutters is coupled to the conveying apparatus by a frame. The gutters are coupled together in one or more series of parallel gutters and are displaced by a motor driven endless chain system between a work position underneath the suspended dripping electrodes and a rest position which permits the electrodes to be inserted into or extracted from electrolysis cells by the conveying apparatus. The gutters include outlet orifices which communicate electrolyte from the dripping electrodes to a reservoir formed in the frame which couples the drop collector to the conveying apparatus.
