ELECTROFORMED CONDUCTOR FOR TELEPHONE DROP WIRE 1133 

 FINISHED WIRE HANDLING 



The spools of plated wire removed from the take-up stands are rolled 

 onto a chock-strip in the operating aisle centrally between the two take- 

 up stand lines. This strip serves as a temporary storage and spots the 

 finished wire spools directly under and overhead monorail. The spools are 

 picked up from this strip with a hair-pin hook on a trolley-mounted elec- 

 tric hoist and pushed to a pallet-loading area at the open end of the 

 take-up line. Each pallet holds four spools of wire, and both spools and 

 pallets are of such size that four spools may be placed with a single spot- 

 ting of the pallet. The pallets are of special design, double-sided and made 

 for stacking. Loaded pallets can be stacked four deep, the upper pallets 

 resting on the heads of the spools on the lower pallets. The spool heads 

 are made of cast steel and are of ample strength to sustain this load. 



The loaded skids are picked up with an electric fork truck and moved 

 to the loading dock at the far end of the building. Here the loaded pallet 

 is moved directly into a motor-tractor drawn van parked at one of 2 

 loading doors. The van holds one day's (24 hours) output of electro- 

 formed wire. 



SAFETY FEATURES 



The electroforming process involves the use of chemicals all of which 

 are dangerous when taken internally. Many are corrosive to the skin 

 and some form poisonous vapors and gases under abnormal conditions. 

 Specifically, extensive use of acids and cyanides demanded that extreme 

 care be exercised in the layout of chemical storage and handling areas 

 associated with each unit process. To aid in preventing any accidental 

 mixing of these compounds and the possible generation of lethal hy- 

 drocyanic acid gas, a number of safety features are embodied in the 

 design of the machine. The more important of these features are the 

 following : 



1. Individual pits for isolating the storage, mixing and filtering equip- 

 ment associated with each unit process have been installed. By this 

 action any overflow from a storage reservoir or solution leak in the hand- 

 ling equipment of any unit process will be confined to its own pit and 

 may be neutralized and flushed to sewer. 



2. Whenever acid and cyanide compounds occupy adjacent locations 

 in the chemical storage and handling area, chemically resistant protective 

 barriers have been erected between them. 



3. Air wipers, water wash cells, and steam wipers have been installed 

 in the processing sections of the machine between each acid and cyanide
