9- Claims.- (Cl. 15-439 This invention relates-to a fountain applicator and more particularly to'a fountain brush.

An object of this invention is to provide an improved and simplifiedforin of fountain'applicator or brush especially'ada'ptedfor use in applying lacquers on walls and the likearid for covering scratches,-mars, etc. on metal, wood, or unfinished surfaces of other materials.

Still another object of this invention is to provide a fountain applicator of the type having a closure cap and wherein the cap isutiliz'e'd to maintain the fluid control valve of the applicator open when the cap is on the applicator body or reservoir-l In accordance with the general features of this invention there is provided a fountain applicator comprising a fluid containing. reservoir, a bristle brush at one end' thereof, resiliently urged means controllingflow of fluid from the reservoir to the brush, and a closure cap for the brush end of the'reservoir guided on" the reservoir to direct an internal projection into the brush to depress and open the means whereby fluid flows to the brush when the cap is on the reservoir end; g

Another feature of the invention relates to the provision of an agitator in the reservoir of the applicator movable to stir the fluid'entirely independent of the valve control means.

Other objects and features of this invention may more fully appear from thefollowing detailed description taken in connection with the accompanying drawings which illustrate several embodiments thereof and in which Figure" 1 is a side elevation of my novel applicator;-

Figure 2 is an enlarged vertical cross sectional view through the applicator partly broken away, and showing the cap in closure position on the" applicator reservoir;

Figure 3 is an enlarged fragmentary cross-sectional View similar to- Figure 2 showing the ejected position of the bristle brush when the cap is removed";

Figure4- is a cross-sectional View taken on the line Figure 5: isla fragmentary cross-sectional view similar to 'gu e 3 showing a modified form of applicator; and Figure -6 is across sectional view taken on the line VI- VI of Figure 5 looking downwardly.

Disposed inside ofthe bore 13 of the plug or insert 16 i is a helical compre'ssi'on spring 19, one end of a which apnea Washer 20 press fitted into a countersunk opening 2,806,239 Patented Sept. 17, 1957 2 21 at one end of the bore 18. The other end of the spring 19 abuts a guide Washer 22 carried on an annular enlargement or shoulder 23 of a brush stem 25.

Both the

washers

20 and 22 may be made of any suitable material, such, for example, as a synthetic plastic. Each of them has a central opening of larger diameter than that of the stem proper so that the stem loosely passes through these washers. It will also be noted from Figure 4 that the washer 22 has cut away or fiat portions 26 spaced from the wall of the tubular plug 16 so that fluid in the upper part of the reservoir 10 can flow between the edges of this washer 22 and the inside wall of the plug 16' while the washer still acts as a guide for the stem 25.

The enlarged or shouldered end 23 of the stem 25 is cupped, as indicated at 27 in Figure 3, and has embedded in it the base 28 of a bristle brush 30.

It will also be noted that the external or free end of the tubular plug 16 is reduced and rounded at 31 and has a reduced opening. 32 comprising the valve opening of the applicator. This opening 32 is of such a size, as show in Figure 3, that the brush base 28 can loosely telescope the same when the applicator stem 25 is in closed position. When in this position the lower edge of the shouldered end 23 of the stem contacts at 33' the interior wall of the open end 31 of the applicator to form a valve for metering or shutting olf the flow of fluid from the reservoir or barrel 11 to the bristles of brush 30. The shouldered'end 23 of the stem 25 is maintained in this closed position under the resilient pressure of the compression spring 19.

Also disposed in the barrel 11 of the reservoir 10 is an annular Weight 35 which is between the plug- 16 and the closed end of the reservoir. Itis movable in the; barrel or casing 11 entirely independent of the movement-of the stem 25, which'stem is free to move through the center of the Weight as shownin Figure 2.

The weight is effective as an agitator for stirring up the fluid in the reservoir by simply shaking the fountain reservoir or by turning it upside-down.

My invention is especially concerned with the coaction of the cap 13 with the bristle brush 30 or more specifically with the valve stem 25. As shown in Figure 2, the cap has embedded in the inside surface of its closed end, a

pointed metal pin 40 depending centrally in the cap to terminate within the cap. The pin is of such length that the cap will be guided by the nozzle to align the pin longitudinally so that it will centrally penetrate the bristles of brush 30 and strike the brush base 28 for raising the valve shoulder 23 out of valve closing position.

In other words, the cap 13 is placed on the nozzle, guided by its side wall on the side wall of the nozzleto align the pin with the brush andas the cap is screwed onto the threads 12, the pin 40 penetrates the bristles of brush 30, impinging against the valve or stem enlargement 23 and moving it from the closed valve position shown in- Figure 3 to the open position shown in Figure 2. When in this latter position, the fluid in' the reservoir can freely flow downwardly around the bristles 'of' the brush 30 which has been pushed back into the open end 31 of the plug 16. a

The tip 41 of the open end of the plug end- 31- is adapted, when the cap is on the reservoir, to sealingly engage a synthetic plastic insert 42 or washer embedded in the cap around the pin 40. This seal serves to mini mize evaporation of the fluid around and in the bristles of brush 30 and yet enables the bristles to be maintained and kept moist by the fluid.

In Figures 5 and 6 I have illustrated a modification of the invention wherein the parts common to these figures and Figure 3 are, for purposes of simplicity, given the same reference characters. Actually, the only diflerence resides in the construction of the enlarged end 23' of the stem 25'. In this form the spacing guide or washer 22' is formed integral with the stem enlarged end 23'. This guide 22' has spaced radial'ears or lugs 26 for contact ing the inside surface of the reservoir plug 16. Also, the bristles of brush 30' are embedded directly in the lower integral end 28' of the enlargement or shoulder 23'. Otherwise, this form of the invention is the same and operates in the same manner as the first described embodiment.

As illustrated in Figures 3 and when the brush is projected beyond the nozzle end 31, the spring holds the valve on the tapered seat to stop flow to the brush.

When sufiicient end load is placed on the brush it will retract into the bore to unseat the valve and permit flow of fluid to the brush. This flow will be controlled or metered by the valve in accordance with the spacing of the valve from the seat. Thus the end load on the brush will not only control the distance which the bristles project but will also control the degree of valve opening to modulate fluid flow to the brush.
