Abstract

Copper anodes that are used in copper plating tanks occasionally fall to the bottom of the tank from which they must be removed. A retrieving device that removes the anode without any hazard to personnel or without contaminating the contents of the tank is described. As seen in the drawing, the retriever is constructed of 7/16 inch diameter stainless steel rod. When handles 1 are squeezed together, rod 2 is driven upward relative to rod 3 which is driven downward relative to rod 2, as indicated by the arrows. As rod 2 moves upward, a single foot 4, which is connected to rod 2, is moved upward to open from a double foot 5 which is connected to rod 3. Simultaneously, as rods 2, 3 are moving in the direction of the arrows, a pair of spring- restraining stops 6 and 7 are moved together such that spring 8 is placed in compression.

Copper Anode Retriever

Copper anodes that are used in copper plating tanks occasionally fall to the bottom of the tank from which they must be removed. A retrieving device that removes the anode without any hazard to personnel or without contaminating the contents of the tank is described. As seen in the drawing, the retriever is constructed of 7/16 inch diameter stainless steel rod. When handles 1 are squeezed together, rod 2 is driven upward relative to rod 3 which is driven downward relative to rod 2, as indicated by the arrows. As rod 2 moves upward, a single foot 4, which is connected to rod 2, is moved upward to open from a double foot 5 which is connected to rod 3. Simultaneously, as rods 2, 3 are moving in the direction of the arrows, a pair of spring- restraining stops 6 and 7 are moved together such that spring 8 is placed in compression. It is in this open position that an anode can be grasped for removal. The anode (not shown) would be located between the top foot 4 and bottom feet 5. When the handles 1 are released, the spring 8 is partially removed from compression and top foot 4 and bottom feet 5 close to hold anode with force of spring 8. Rods 2 and 3 are secured together by U-shaped pieces 9. The U- shaped pieces are welded to the rods 2, 3 at the open ends of the pieces.
