Реферат: 6300. Beckmann, H. March 23. Small articles, plating.-Relates to apparatus for plating small articles, such as nuts and bolts, small parts and spokes of velocipedes, stair rods, and the like. The plating-liquid is placed in a vat A, and a horizontal shaft B is supported and rotated therein by pulleys D, D' and endless cords C, C<1>. Upon the shaft at each end, Fig. 1, is a wheel E, G, that at one end being much larger than that at the other. Each wheel consists of metallic spokes F. The wheels support between each alternate and opposite pair of spokes a perforated or gauzelike metallic chamber H into which the articles to be plated are placed. The shaft is in electrical connection with the negative pole of a suitable battery, the positive pole being in connection with the anode plate suspended within the electrolyte. Auxiliary anodes J may be arranged between the chambers H. In Fig. 3, in addition to the drumlike arrangement E', as in Fig. 1, there are two adjustable skeleton wheels or discs K mounted upon the shaft B, and adapted to support articles X, such as spokes, placed between them.
