The Aerograph.

First, therefore, comes the Aerograph Co.'s Spray Painter. This instrument is of the concentric jet type, and was one of the first of the kind made in Europe. It is capable of excellent work. In Fig. 35 is shown one form of the handpiece. A flexible tube for compressed air connects with the nipple A. The finger lever F controls both the air valve and a colour valve in the nozzle N, so that little or much colour may be allowed to pass out into the current of escaping air.

The colour may be supplied under pressure, through a flexible tube from a large paint pot, and pass through the tube P to the nozzle N, or in smaller quantities from a cup C, which is attachable at B, and when so attached cuts off the supply through the tube P. This cup is useful when small quantities of colour are wanted with frequent changes. A ball joint permits work to be done in either an upward or downward direction.
