562,153. Electroplating plant. CANNING & CO., Ltd., W., and POPE, G. A. March 12, 1943, No. 4061. [Class 41] An electroplating plant comprising a long bath a, Figs. 1, 2, preferably consisting of a straight portion terminating in semicircular ends at which may be disposed auxiliary cleaning and washing baths, is provided with one or more anode carriers e, Fig. 5, from which are suspended anodes f extending across the width of the bath so as to divide it into a series of cells, means being provided for intermittently raising and lowering the carriers and for intermittently moving through the successive cells the workpieces, which are either contained in rotary barrels d, as in the construction shown, or are suspended from a suitable conveyer. Spindles h, k, driven from an electric motor i and mounted in a framework g, carry endless chains n interconnected by rods p to which are secured carrier q supporting the bearing brackets x and spindles v of the barrels d. The brackets carry rollers - z running along a horizontal track 2 on the framework, which track has a section 3 capable of being moved outwardly by levers 4 operated from a cam 5 at the positions where it is required to lift the barrels out of the bath a. The barrels are rotated by sprocket gearing from a pair of interconnected chains 12 driven from a second motor 28, clutches 23, 24, actuated by engagement with a ramp 26, being provided to stop the rotation for loading and unloading of the barrels. Each anode carrier e comprises a framework attached to a pair of slides 34 vertically movable on guides 37, each slide being connected to one side of one of a pair of endless chains 39 passing over sprockets 40, 41 and carrying a counterweighting bar 43, the chains being actuated when required by a third electric motor 45. The motors i, 28 and 45 may be controlled by cam-operated or other switches to render the operations of the plant automatic.
