Larger establishments, however, findit cheaper and better in every way to use steam jacketedtanks as shown in Fig. 16. These can be purchased inregular sizes holding from three gallons up to forty gal-lons, and the smaller and medium sizes are rapidly find-ing favor in many machine shops and factories where itis important to cleanse the work quickly and cheaply. MODERN ELECTRO PLATING. 45 Still larger tanks for heavy work are made of boiler ironand heated by a steam coil placed in the bottom of thetank; this usually is allowed to simply lie upon the bot-tom of the tank, so that it may be readily removed. Fig. ib. should it become necessary in cleaning the tank orrepairing the coil. In arranging the tanks in the plating room much willdepend upon the work to be done and the space that isavailable; the only rule that can be given, therefore, is tofollow the order in which the work is handled in bothpolishing and plating rooms, so that little time and labor 46 MODERN ELECTRO PLATING. will be lost in carrying work back and forth, with theconsequent dripping of the lye and acids, etc., upon thefloor. In large establishments it is frequently an impor-tant item to have the work thus proceed in a straight line,and where it is necessary the tanks for hot water andlye, dips, etc., are duplicated to avoid carrying the workabout. Smaller establishments will, of course, be gov-erned
