FOUNTAIN PAINTBRUSH Filed Dec. 2, 1948 Zhwentor Mark Sass (Ittomeg Patented Jan. 9, 1951 UNITED STATES PATENT OFFICE FOUNTAIN PAINTBRUSH Mark Soss, Spokane, Wash.

Application December 2, 1948, Serial No. 63,010

1 Claim. 1

My present invention relates to an improved fountain paint brush of the type including a tubular handle having communication with the bristles so that paint may be supplied to the bristles through the tubular handle for application by brushing without the need for continual dipping into a supply of paint.

It is therefore one object of the invention to provide a paint brush which is adapted to be secured to a paint supply which, under control, supplies paint to the bristles by means of air under pressure.

Another object of the invention is to provide a paint brush which will distribute the paint so received evenly to the bristles of the brush so that a smooth paint job may be accomplished.

Another object of the invention is to provide a paint brush with a tubular handle which is externally threaded to facilitate securing to a conventional spray gun by means of an internally threaded sleeve.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention according to the best mode I have thus far devised, but it will be understood that various changes and alterations may be made in the exemplified structure within the scope of the appended claim.

In the drawings:

Figure 1 is a view in side elevation.

Figure 2 is a fragmentary vertical sectional view of the brush and its securing means.

Figure 3 is a transverse sectional view as at line 33 of Fig. 1. i

Figure 4 incorporates a modified type of spray gun which may be used with the brush of my invention.

Figure 5 is a fragmentary view upon an enlarged scale showing the connection between the brush and the spray gun in longitudinal section.

Referring now to the drawings I have illustrated the present preferred embodiment of my invention as comprising a paint brush having bristles 2 mounted in the frame i by means of a suitable material such as rubber F1. .A. tubular handle 6 is formed integrally with the frame 4 and is threaded externally as at Ill to ccact with an internally threaded sleeve ii. The sleeve 12 is provided with a head l4 knurled on its periphspray gun 22 having a hose connection 24 extending to a source of air under pressure (not shown) to operate the spray gun i the usual manner. Jet 29 is provided with a shoulder 28 and when sleeve I2 is threaded on the handle 8 and tightened, handle 8 is drawn inwardly pressing its end face against gasket 30 and causing a seal to be formed between handle 8 and shoulder 28. Within the tubular handle 8 I have provided a sleeve 32 which extends through the mounting rubber 6 into the base or rear portion of the bristles 2. Frictionally secured about the end of the sleeve 32 is a nozzle 34 having an elongated orifice 35 for the purpose of evenly dispersing the inflowing paint over the bristles 2 for application to a surface.

It will be apparent thatwith a supply of paint in the container 38 of the spray gun and its valve which is of conventional formation and opened by actuating lever 42, paint will flow under pressure and be emitted from the jet 2!] into the sleeve 32, and it will carry into the bristles and be. dispersed over the bristles 2 from which it may be brushed onto the surface to be painted.

It is possible to perform a better paint job ,having the qualities of a brush painted surface and also eliminate the waste of paint prevalent in spray gun painting. Also the time consumed in dipping the brush when painting is used in brushing thus completing the job in a fraction of the time necessary in the old brush and bucket method. 7

In Figure 4 I have shown a modified form of paint container M on the paint spray gun which is of lesser length thus providing a lighter tool since the weight of the paint is lessened. The container Mi is provided with a boss 46 having a threaded opening communicating with the container, and a threaded plug 48 is used as a closure and removably screwed into the opening. If desired, paint may be supplied to the container from an elevated source, or otherwise, through a tube connected to this opening.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

A spray gun having a forwardly projecting barrel, a tube of less diameter than the barrel projecting forwardly from said barrel, a conical jet at the front end of said tube spaced forwardly from the barrel and having its rear end surrounded by a circumferentially extending shoulder, a sleeve nut loosely fitting around said shoulder and surrounding said jet and projecting forwardly therefrom and having its rear portion internally thickened and forming a flange fitting snugly about the tube and having its front and rear side faces in abutting engagement with the shoulder and the front end of the barrel, a gasket in said sleeve nut fitting about said jet and against the front side face of said shoulder, a

member having a. rearwardly extending externally threaded tubular neck screwed into said sleeve nut and held in compressing contact with the gasket by the nut and thereby forming a. sealed joint between the neck and the shoulder of said jet, a sleeve entering the neck through the front end thereof and fitting snugly therein with its rear end bearing against said gasket, and a nozzle at the front end of said sleeve.
