Fig. 133 shows a machine with a double spraying nozzle and valve arrangement. This has several advantages over the single pattern; the speed is almost double, and one jet can be put out of action if desired when working in cramped places. It is a powerful machine with 12 gallon tank and strong lever pump. It is supplied with large wheels and is easily moved about, and is eminently suitable for anyone having a large quantity of work to do quickly.
In dealing with very high buildings either the single or double nozzle is attached to a bamboo pole, as shown in Fig. 134.

In Fig. 135 is shown an excellent machine suitable for spraying whitewash, distempers and disinfectants. It is manufactured by the E. C. Brown Co., of Rochester, N.Y. The pump is of a simple but effective character; the valves are located so that they can be opened instantly and are fitted with springs so that the operator can pump while the machine is pointed in a downward direction. The strainer has five inches of screen surface and the screen can be instantly removed and cleaned. The pump barrel projects beyond the hand and serves as an extension rod. The nozzle is guaranteed not to clog, and is fitted with Messrs. Brown's patented screen arrangement. It throws four different kinds of spray, one a solid stream, the second a broad carrying spray, the third a long driving spray for ceilings and tops of walls, and the fourth a fine spray which may occasionally become of service for spraying work near at hand.
There are several other makes of machines suitable for whitewash spraying, among them one manufactured by Merryweather and Co., Greenwich Road, S.E., The Bean Spray Pump Co., Los Angeles, California, U.S.A., and the Four Oaks Spraying Machine Co., Sutton Coldfield, Birmingham. The last named is particularly well adapted for spraying insecticides upon fruit and other trees.
