It will be noticed that to each stand isbrought a gas pipe and a compressed-air pipe, by which eachworkman can form a blow torch for soldering, etc. Through the courtesy of G. H. Sweetlove, the foreman ofthe armature department, and of the master mechanic, , the following statistics as to the cost of producing COST OF LABOR AND MATERIAL FOR MAKING FIELD COILS COM-PLETE—TORONTO RAILWAY SHOPS. BLOWING OUT ARMATURE WITH COMPRESSED AIR, TORONTORAILWAY SHOPS field and armature coils of various types, as taken from shoprecords, are here given: It is understood the cost of materials will rise and fall withthe market, but the figures given are good averages. states that the labor item can be reduced on arma-tures if taping machines are used for taping coils and if band-ing machines are used for banding armatures. The arma-ture cores must be in good condition, or it will take moretime to prepare them for winding. At the Toronto shopseach winder prepares his own armature core for winding,including stripping, cleaning and filing. He also winds andconnects his own armature. By this method it is possibleto hold each man responsible for all the work on each arma-ture. ARMATURE RACKS For holding armatures while they are in the shops, racks areprovided along one wall in the armature room, as shown in Wire Glace belting No. 6 CC cable Tape, Competit
