Betterresults can usually be obtained if curved anodes areused, thus providing an anode surface below the cyl-inder as well as at the sides. The cathode connectionto the article is formed by a contact with metal pen-. Tig. 61.—Oblique Plating Barrel. This Type Is Quite as Efficient as the Horizontal Machine and May Be Employed for Smaller Quantities of Work. (Hanson & Van Winkle Co.) dants suspended from the metal axis of the axis is, of course, connected to the negative busbar. The cylinder is constructed of a non-metalliesubstance, such as bakelite, and is thus not affectedby the plating currents. The barrel type machineis also designed as shown in Fig. 61. In operating any of these barrel-type plating ma- 102 The Modern Electro plater chines it must be remembered that they are quitesimilar to the still tank as far as the deposition pro-cess is concerned. The speed of rotation must beslow, fifteen to twenty being sufficient. Nogood and much harm will result if the barrel is op-erated at a higher speed. AUTOMATIC PLATING MACHINERY The trend of the industrial world is toward theuse of automatic machinery. While electroplatingrequires, perhaps, more of the human element th
