Emery Band Machines. — These are used for polishing work of irregular form. The bands are dressed with powdered emery in the same manner as a buffing wheel. Their flexibility allows of their application to the surface of the most irregularly shaped articles, such as spade and shovel straps, brass cocks, bends, mouldings, beads, hinges, latches, levers, straps, joints, connecting rods, catches and stove-grate fittings, while their rapid motion imparts a rigidity sufficient for the band to withstand a reasonable amount of pressure being brought to bear upon it, the workman pressing the article to be ground closely against the emery band. Many different forms and sizes of machine are made in order to meet the requirements of the varied surfaces, such as flats, corners, curves and bends to be dealt with. The Bench Emery Band Polishing Machine (fig. 126) consists of two cast iron headstocks, the centres of which are 3 feet 3 inches apart; each headstock is fitted with a steel spindle carrying a 7 inch by 4 inch double-flanged pulley over which the emery band passes; one of the headstocks has a cast iron planed bottom slide, with a screw and handle for regulating the tension on the band; and a 4¼ inch by 2¼ inch driving pulley is fitted to the other headstock; midway between them is an adjustable angle rest for supporting the band when extra pressure is brought to bear upon it. |
