Among other goods produced by Dale Hall are artists’ palettes, slabs, tiles, mullers, &c.; photographic articles (trays, baths, troughs, stands, funnels, and every other requisite); chemical and druggists’ goods (mortars and pestles, leech-jars, covered jars, evaporating pans, inhalers, pill tiles, and every other article); scent bottles and vases; toilet and other boxes; sign-board letters; door furniture; ironmongers’ fittings; and fancy articles of various kinds. Garden and ornamental flower-pots, garden-seats, suspenders, fern and other stands, &c., are also made. In sanitary ware, Messrs. Bates, Walker, & Co. rank very high, and produce every known article and of faultless excellence in quality. They are patentees of an improved “wedge commode pan,” the principle of which is shown in Fig. 398; its advantage in the sick chamber or travelling carriage being very apparent. Another and very important patent taken out by the firm, is for self-locking and self-adjusting covers for jugs, tea-pots, &c. The principle, which is one of the most simple, but at the same time most successful yet adopted for preventing the falling off of the lid in the act of pouring, is shown in Figs. 400 to 403. One of the great specialities of the firm is the process by which printing in two to five colours is successfully transferred on to the ware while in biscuit state, and is, therefore, under the glaze. By this process, the invention of Messrs. Mayer Brothers, vases, dinner and other services, and other articles, are decorated in thoroughly good taste; and, through there being no touching whatever by the pencil, as the entire pattern is transferred at one operation from the coloured print, they are produced at a comparatively moderate cost. The effect is soft and delicate, and is capable of considerable development. [Illustration: Fig. 404.] [Illustration: Fig. 405.] The marks of Messrs. Mayer were T. J & J MAYER; MAYER BROS, &c. Those of the present firm are BATES, WALKER & CO. PATENTEES, on an oval ribbon, with date, &c., of registration inside; and a nude figure kneeling and holding an ewer in front of him, on a tablet with the date 1790. This is introduced in a variety of ways, with the initials B. W. & CO., and the name of the pattern, &c. The markets supplied are both home and foreign. * * * * *
