Appletons' cyclopaedia of applied mechanics: a dictionary of mechanical engineering and the mechanical arts . LAUNDRY MACHINERY 275 geared to the driving-shaft. The capacity of the machine is about 700 dozen of collars and cuffs ata washing. The cylinders are 40 in. in diameter, and make from 60 to 65 revolutions a minute. In Fig. 2*735 is shown the Nonpareil machine, which is entirely different in principle from the ma-chines above described. Four vibrating arms, depending from a horizontal cross-piece, are connected. by cranks to the driving-shaft. These cranks are placed at different angles

The capacity of the machine is about 700 dozen of collars and cuffs ata washing. The cylinders are 40 in. in diameter, and make from 60 to 65 revolutions a minute. In Fig. 2*735 is shown the Nonpareil machine, which is entirely different in principle from the ma-chines above described. Four vibrating arms, depending from a horizontal cross-piece, are connected. by cranks to the driving-shaft. These cranks are placed at different angles on the shaft, so as togive the arms a uniform motion by pairs. On the ends of the arms are the rubbing-boards. Themachine is run at a speed which gives 440 strokes of the arms per minute. This rapid motion, com-bined with the positive action of the beaters, squeezes the goods between the inclined corrugatedfaces of the rubbing-boards and the body of the machine. 873S- The arrangement of cranksis such that while one pairof boards are squeezing thegoods the other pair havereceded, and the fabric isopening and reabsorbing thewater. By the rubbing-boards the goods are rolledover and over until they arethoroughly washed. Thismachine is much used in ho-tels and large Machines.—The principle of rollingover or kneading the clotheshas been applied success-fully in the construction ofhand-washing machines, bet-ter results having been ob-tained from apparatus thusconstructed than from ma-chi
