Self-contained spray gun apparatus with spherical paint cup

A self-contained paint spraying system, comprising:

• a paint spray gun for spraying paint, said spray gun having a spray nozzle, paint inlet means, means for connecting the gun with a source of air under pressure, and control means for controlling flow of air and paint through the gun;
• a spherically shaped paint cup attached directly to said paint inlet means for holding paint to be supplied to the gun, whereby said paint cup moves in unison with said gun;
• and
• a flexible paint pick-up connected to the paint inlet means and extending into the paint cup into proximity with an inner surface of the spherical wall thereof, said paint pick-up having means for maintaining it in contact with the inner surface of the cup and for automatically positioning it at the lowest point in the cup as the gun and attached cup are moved through different orientations, whereby the paint pick-up remains immersed in paint regardless of the position of the gun and cup.
