It will also be noted that a thermometer 5B is employed in the pipe 52. Extending into the chamber l5 at the upper end thereof is another thermometer 59, so that, at all times, a reading can be taken of the temperature of the heat transmitting medium in the upper portion of said chamber.

Suitable valve controlled drains are provided for the chambers l5 and IS. The drain for the chamber I5 is shown at 60 and for the chamber l6 at 6|.

In the drawing, we have shown in the pipe line 5| suitable means, as at 62 for supplyof air to said pipe from a suitable source of pressure air supply, the inlet pipe being shown'at G3 and, at 64, is shown a control valve to control supply of air to the coil 50., At 31' is shown a valve controlled-paint drain for the pipes 3H1.

The present invention does not deal' spe-' ciflcally with the structure of the spray gun 32. However, suitable means, as for example, a trig ger 65 is provided on the gun for controlling spray discharge of paint or other fluid from the nozzle end 58 of the gun. In the use of them;-
