H- W. HEMPEL FOUNTAIN BRUSH Aug. 24, 1954 Filed Aug. 3; 1949 Patented Aug. 24, 1954 UNITED STATES PATENT orifice FOUNTAIN BRUSH Herbert NV.

Hempel, Belleville, Ill., assigner to Marsh Stencil Machine Company, Belleville, Ill., a corporation of Illinois Application August 3, 1949, Serial No. 108,281

` (o1. i- 139) l Therefore, an object of the present inventionl is to provide a novel general purpose fountain brush which incorporates a one-piece valve, guide and bristle holding ferrule. i

Another object is to provide a novel general purpose fountain brush constructed to apply liquid to applicator bristles readily and through a short path to minimize trapped liquid on the exhaust side of the valve and to eliminate bristle flooding on closing of the brush valve.

Another object is to provide a novel general purpose fountain brush in which the valve seat is positioned at the extreme lower end of the housing to give immediate fluid-bristles contact.

Another object is to provide a novel general purpose fountainbrush in which a spring biasing the valve into closed relation limits the valve opening to avoidflooding through compressing into solid relation.

Another object is to provide a novel general purpose fountain brush in which the guide portion of the one-piece valve, guide and ferrule contacts the housing at spaced points and permits passage of liquid in any position.

Another object is to provide a novel general purpose fountain brush constructed to incorporate a replaceable closed end liquid reservoir of any standard or selected design.

Another object is to provide a novel general purpose fountain brush which is adapted to be used with a Wide variety of fluids and for numerous purposes.

Another object is to provide a novel general purpose fountain brush which is inexpensive to manufacture, which may be readily employed to `apply any selected fluid, which is simple inconstruction rendering cleaning and maintenance quick and sure, which is adapted to be used for many applications Without mechanical failure, and which presents a neat appearance.

The foregoing and other objects and advantages are apparent from the following descripcomprehends a one-piece valve,`

tion taken with the accompanying drawing, in which:

Fig. l is a side elevational View of a general purpose fountain brush constructed in accordance with the teachings of the present invention;

Fig. 2 is an enlarged diametric cross-sectional view on substantially the line 2-2 of Fig. 1; and

Fig, 3 is a transverse cross-sectional View on substantially the line 3-3 of Fig. 2.

Referring to the drawing more particularly by reference numerals, I0 indicates generally a general purpose fountain brush incorporating the concepts of the present invention which includes a uid reservoir handle I2 open at one end and closed `at the other end, a housing I4, a onepiece valve, guide bristle ferrule lli, a compression spring I8, a washer 20, and bristles 22.

The one-piece valve, guide and bristle ferrule It includes a cylindrical body 24, a frusto-conical valve portion 26 preferably sloped at thirty degrees, and a guide flange 28 shown as of hexagonal form, the points of which slidingly engage the interior of the housing I4. The bristles 22 extend into the body 24. The valve portion 26 may be formed as a portion of a sphere.

The housing I4 includes an elongated cylindrical portion 30 of` small internal diameter and a short cylindrical portion 32 of larger internal diameter which are connected by a frusto-conical portion `Sli. `The portion 34 includes an annular shelf 36 at its upper end which receives the washer 20. Thel portion `32 has internalthreads 38 which receive external threads 40 at the open end of the reservoir-handle I2. The free edge of the open end of the reservoir-handle I2 engages the washer 20 to effect a seal. The washer `2l] has an opening 42 for passage of iiuid from the reservoir-handle I2 into the housing I4. The Washer 2|] is held in assembled position by a press t, crimp, or adhesive, so that it will not be spring ejected or fall out when the reservoir handle I2 is removed for filling or replacement.

The portion 30 of the housing I4 includes an opening 44 and a thirty degree slope valve seat 46. The one-piece valve, guide and bristle ferrule I6 is disposed within the portion 3u with the valve portion 26 biased into engagement with the valve seat 46 by the spring I 8, one end of which engages the underside of the washer 20 and the other end the top of the guide iiange 2S. The bristles 22 extend through the opening 44.

For a small fountain brush I0 of the actual size as shown in Fig. 1, it is desirable that full compression of the spring I8 permits longitudinal travel of the one-piece valve, guide and bristle ferrule I6 of approximately one-sixteenth of an inch. Manifestly, this travel may be changed to suit particular applications of the brush I0.

In operation, a selected liquid is poured in the reservoir-handle I2 and the housing I4 with its several contained elements, as illustrated in Fig. 2, is screwed onto the open end thereof. The brush I0 is then disposed with the bristles 22 depending. The liquid will ow from the reservoir-handle I2 through the opening d2 into the housing i4, thence past the flange 28 and around the body 24. Pressure of the free ends of the bristles 22 against any surface when thus held in depending position will lift the vvalve portion 29 from the valve seat 46 and permit liquid to flow onto the bristles 22 by the short path only slightly greater than the depth of the valve portion 26. Air will replace discharged liquid. Upon release of the pressure at the ends of the bristles 22, as by lifting the brush I0, or releasing down- Ward pressure, the spring I8 will quickly seat the valve portion 2t with minimum trapped liquid. As is clear from the drawing, the guide flange 28 Vserves to center the valve portion 2B. As stated above, total compression of the spring i8 acts as a stop to prevent raising of the valve portion 2S more than a predetermined distance, thereby eliminating undue flooding of the bristles 22, but permitting adequate flow for heavy liquid application.

The reservoir-handle I2 is shown as of cylindrical form and of plastic for observation of its contents. A standard lled container of glass or other material and of any desired configuration may be employed.

1t is manifest that the fountain brush i9 may be used for many purposes, such as the application of paints, coatings, liquid cleaners and spot removers, adhesives, shoe polishes, tool room bluing solutions, water, ink, and a host of other liquids.

Palpably, there has been provided a general purpose fountain brush which fulfills the objects and advantages sought therefor.

it is to be understood that the foregoing description and the accompanying drawing have been given by way of illustration and example.

4it is also to be understood that changes in form of the elements, rearrangement of parts, and substitution of equivalent elements, which will be obvious to those skilled in the art, are contemplated as within the scope of the present invention which is limited only by the claims which follow.

What is claimed is:

1. A fountain brush comprising, in combination, an elongated housing member having a passageway therethrough, said passageway being formed to provide a circular discharge opening at one end of the housing, a circular inlet opening at the other end of the lhousing, and an elongated cylindrical passage interconnecting said openings, said discharge opening being smaller in diameter than any other portion of said passageway, said cylindrical passage being intermediate in diameter between said openings, said passageway being further formed to provide a circular Valve seat immediately adjacent said discharge opening, a ferrule member disposed in said cylindrical passage and being coaxially movable therein, said ferrule member having one of its ends shaped for valving engagement with said valve seat and the other of its ends shaped for peripherally spaced slidable engagement with the walls of said cylindrical passage, a plurality of bristles secured in said ferrule and extending beyond said one end thereof and through said discharge opening, a washer secured in said/inlet opening, a compression spring interposed between said ferrule member and said washer for biasing the former toward said valve seat, and a fluid reservoir removably Connected to said inlet v opening.

2. The combination of claim l wherein the bristles are formed into a circular bundle, said bundle being in continuous slidable engagement with said discharge opening.

3.v The combination of claim 1 wherein the convolutions of the spring are so spaced as to provide only a predetermined limited coaxial movement of the ferrule before the spring is compressed to a minimum length.
