Fig. 38.—Painting a Gasometer.
In Fig. 36 is illustrated a pistol pattern of the Aerograph, which has a large side cup which can be sprayed at any angle, being adjusted to facilitate spraying in an upward, downward or horizontal position. Thus work can be done by it on table, wall or ceiling. The cup referred to contains the paint or other liquid to be sprayed, and a series of cups may be provided for a quick change of colour, if desired, as will be readily understood.
In cases where electric power is available, the electric motor outfit shown in Fig. 37 will be found very serviceable. It may be described as a "spray painter" outfit complete, and it includes a 1 h.p. motor mounted on a trolley ready for use, which can be employed for many different classes of work. In Fig. 38 it is shown being used for spraying paint on a gas holder. It would appear that this outfit might be employed for ship bottom painting, provided that the necessary scaffolding or its equivalent were available.
Fig. 39.—Small Aerograph for Delicate Work, Lining, Lettering, etc.
Going to the other extreme, a form of Aerograph, suitable for very delicate work, is shown in Fig. 39. This may be used for photograph retouching, pottery, and small decorative work generally—in fact, it is suitable for any work requiring delicacy of work.
In another chapter the subject of artistic work done by means of compressed air is considered at some length, and a number of specimens of work executed by this process are given.
