8' Claims'.

'i'his invention relates'` to paint brushes,y and more particularly to afountain type feed of paint brush.

Known to me are the endeavors made to feed paint or like wall` coating material to a bristle paint brushwhereby the labor of dipping the brush into the. paint can. or reservoir is minimized. However, th-e process of painting is not merely that of distributing paint, and the efforts as heretofore made for automatically feeding liquidto a paint `brush destroyed or` inhibited. one of. the primary purposes of ther bristle. brush.,.to wit, the distribution'of the paint on.l the wall or surface after its application toy the wall or surface.

It is accordingly an object ofk my invention` to provide a fountain type paint brushlwhch permits application et the coating material from aremote reservoir and which permits distribution ofv the paint or coating material, on the wall by the brush bristles, Without impairing the efficiency of the, brush, or requiring; any new` orf different techniqueto beexhibited by the painter in working in thecoating, materials or paint on the surfalce'.

I have found that an external applicationof the .paint to the paint brush bristles in a manner not to interfere with the effectiveness of.' the bristles and to take advantageof the cupping or enveloping action of thebristles von the surface. aboutthe liquid distributor, makes the expedient` of a fountain type of paint brush commerciallyA prac; ticable. I have further found that by theemployment of a manifold. which is flexible and externally located, little or no change in design of the bristle construction need be made; and this construction may be availed of efficiently, to carry out the` steps of' applying the paint or coating material to the wall surface, and' there,- after working in or distributing the` coating material into the Wall surface without impairing Vthe efficiency, design orma'nner'of manipulation of this contrivance.

Still more particularly it is an object of my invention to`r combine with a brush having a fountain feed, a manifold" for applying the surface coating material or paint tothe outer face bristles and combine'with the bristles as they are warped or flexedvin normal position on the surface, means for efficientlyV distributingv the' paint without'streaking or running of the paint or coating material.

Still morel particularly, itis contemplated by my invention to provide in combination with `a paint' brush, a manifold for applying paintor the 55 2 like to the brush, which may be coordinated with the wear and life of the bristles themselves so that the electiveness of the manifold, as to length and position, maybe constant in relation to the bristles.

Other objects of my invention reside inthe provision of a fountain type brush which is ecient in operation, and economical in production and maintenance.

To attain" these objects andI such further obj ects as may appear herein or be hereafter pointed out, l2 make reference to the accompanying drawing forming a part hereofin' which:v

Figure 1" is a longitudinal sectionalview of the combined" fountain' brush' and dispensing container, the brushV being magnified for clarity;

' Figure 2' i's a fragmentary side elevation of the brush assembly;

Figure 3 isa section taken on the line `33 ofy Figure 1 Figure 4 a section taken on the line 4 4 of Figure 3;

Figure 5 is a fragmentary section taken' on the une s-sofrigure 1;

Figure 6' 'is a'view-sliowing the brush in use on a wallv surface;

Figure 7 is a section taken on the line T-T of Figure 6.

Making reference tov the drawing, it is contemplated byv me to feed' paint from a storage receptacle IU; through a tube H, to a brush r2. A pressure head' for' feeding the paint or like liquid material upwardly through the tub'e" ilV may be effected by a cartridge t3 of compressed' gas,l such as carbondioxide which; vby the valve ['4, maintains a pressure headforthe paint', in order to feed it upwardly through 'the tube H. The pressure 4head of compressed gas may be furnished by 'other means, suchk as 'compressed air, furnished bya pump, air compressoror th'elike.

The tube' discharges into an extended length of flexible tubing Hi, whose' terminal' end i5" is connected with the nozzle fl of the duct i8 in the handle I9 of the brush l2. The duct t8V may be fitted, nested 0r recessedwithin a boring'or edge slot of the` handle I9. Inv thel illustration shown, the duct I8 isa boring 2l), intersecting a transverse boring 2|,` within'Y which there is slidaioly mounted the valving element 22; whose opposite ends 23-24 protrude axijacentA the shoulder 25 of' the brush handle. Annular slots 2B- andv 2l' cooperate with a detent 28 to tension the valving element" 22` in oneof two positions. A valve-port 2li"A serves to loringtl'ieduct` f84 communication with the channel 3U, terminating in the side 3| through the ferrule 32 of the brush. The channel tion of the eiectiveness of the bristles to perform 3U is capped by the manifold 33, which has a pair their intended purpose. of lateral ears 34, 34 adjacent the upper edge, By my invention, the established technique of held by fastening elements or screws to the side the painter is maintained for the important 3i of the brush.
