3 Claims.

This invention relates to new and useful improvements in spray gun paint containers and more particularly to a multiple paint spray gun color adapter.

The principal object of the present invention is to provide an assembly comprising a single spray gun in conjunction with a multiple colored paint container and selector means whereby the gun may be adjusted to select the paint color desired, thus requiring only one spray gun for a plurality of different colored paints.

Other objects and advantages of the invention will become apparent to the reader of the following description.

In the drawings:

Figure 1 is a side elevational view'showing the adapter with a spray gun mounted thereon.

Figure 2 is a vertical sectional view through the adapter.

Figure 3 is a top plan view of the adapter.

Figure 4 is a horizontal sectional view through the adapter.

Figure 5 is a side elevational view with parts in section showing the cover plate and suction tubes.

Figure 6 is a side elevational view of one of the paint containers.

Figure 7 is a top plan view of the adapter with all movable parts displaced.

Figure 8 is a top plan view of the gasket.

Figure 9 is a top plan view of the rotary selector.

Figure 10 is a side elevational view of the rotary selector.

Referring to the drawings wherein like numerals designate like parts, it can be seen that the adapter comprises a cylindrical shell 5 having a bottom 6 and being open at its top.

Numeral 1 denotes a top for the shell from which depends a plurality of suction tubes 8, equivalent in number to the number of paint receptacles.

These paint receptacles are denoted by reference characters 9, II), II, l2 and I3 and are clearly shown in Figure 4, they preferably being of segmental shape in horizontal cross section and it is also preferable that several of the receptacles be smaller than the other to receive certain colored paints which are not used frequently or to contain a cleaner liquid which is used between colors.

The inner edges of these receptacles terminate short of each other so as to define a vertical passageway l4, vertically through which a rod l5 may extend, the lower end of this rod being anchored or otherwise secured to the bottom 6 of the shell, while the upper end projects through an opening IS in the cover I, it will be observed here that this opening 6 has a side notch for receiving a key I! projecting laterally from the rod l5, this in order to prevent rotation of the top I.

A resilient gasket I8, cut out to fit the upper edges of the receptacles 9, H], II, I2 and I3, fits in depressions in the bottom of the top I and also has an opening I 9 through which the rod l5 can project.

It can here be seen that the upper end of the rod I5 is formed with threads 20.

Numeral 2| denotes the selector which is in the form of a disk having an opening 22 therein for receiving the lower end of a hollow post 23, the upper end of which terminates within a nut 24. The upper end of the post 23 is beveled as at 25 to fit into the intake portion of a conventional spray gun 26. This intake portion of the spray gun is usually threaded to accommodate a nut equivalent to the nut 24. Thus-a positive connection is established between the spray gun and the eduction tube or post 23.

The disk 2| has a circular opening in the center thereof for receiving the upper threaded end portion l2 of the rod l5 and a wing nut 21 is provided on this threaded end portion of the rod and can be tightened against the disk 2| when the disk has been rotated to register the hollow post 23 with any one of the tubes 8, which, of course, open through the top of the top 1.

Air vents are provided through the top I for each of the receptacles 9 to l3, inclusive, and a single air vent 30 is provided through the selector disk 2 1 adjacent the post 23.

Obviously, when it is desired to change from one color to another, the post 23 can be brought into communication with the small receptacle I2 or l3 containing a cleaning liquid, after which the selector disk 2| can be rotated to communicate the spray gun with the next color selected. In each instance the air vent 30 will be registered with the corresponding air vent 30a in the top 1, and when it is not desired to use the apparatus any longer, a slight movement of the se lector will put the spray gun 26 out of communication with the interior of the adapter and this action will also offset the single air vent 30 of the selector disk 2| with respect to the vent 30a of the top 1.

Obviously, if it is not desired to use multiple colors and one color is to be used over an appreciable period of time and surface of work, the

small receptacles can be entirely removed and one color used in the shell.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is: r

1. In combination, a spr y un, a shell, a p for the shell, individual receptacles in the shell, suction tubes depending from the top and into the individual receptacle, a rotary selector on the top, said spray gun being mounted on the selector, said selector being adapted to be rotated to communicate the gun with any one of the tubes, said receptacles being of segmental formation in horizontal section, and terminating at their inner edges in spaced relation to define a vertical passageway, and a rod extending upwardly from the bottom of the shell and through the top and rotary selector, and having a securin member at the upper end thereof for the selector.

2. In combination, a spray gun, a shell, a top for the shell, individual receptacles in the shell, suction tubes depending from the top and into the individual receptacle, a rotary selector on the top, said spray gun being mounted on the selector, said selector being adapted to be rotated to communicate the gun with any one of the tubes, said receptacles being of segmental formation in horizontal section, and terminating at their inner edges in spaced relation to define a vertical passageway, and a rod extending upwardly from the bottom of the shell and through the top and rotary selector, and having a securing member at the upper end thereof for the se- 1 lector adapted to be tightened against the selector to hold the selector in positive position communicating the gun with a certain tube.

3. In combination, a shell, a series of receptacles in said shell arranged side by side around the axis of the shell, a top for the shell, a spray gun, and means to establish communication between said gun and said receptacles, selectively, comprising a selector rotatable on said top concentrically of said axis, and a hollow mounting for said gun attached to said selector eccentrically of said axis and opening into the gun.
