BRUSH.

Specification of Letters Patent. Patented June 18, 1912.

Application filed June 16, 1911. Serial No. 633,615.

To all whom it may concern:

Be it known that I, HARRISON B. SMITH, a citizen of the United States, residing at Bayside, in the county of Queens and State of New York, have invented new and useful Improvements in Brushes, of which the fol-1 lowing is a specification.

The invention relates to an improvement carrying bodies of difierent types, and when so associated provide a convenient fountain brush for many varied purposes, as will later appear.

The invention in the preferred embodiment of details will be described in the fol lowing specification, with particular reference to the accompanying drawings, in which Figure 1 is a perspective view of the improvement, showing it in position on a reservoir of the preferred type. Fig. 2 is a perspective View of the tube and brush shown connected and detached from the reservoir. Fig. 3- is a longitudinal section through Fig. 2. Fig. 4: is a longitudinal section taken at right angles to the plane of section shown in Fig. 3. Fig. 5 is a cross section on the line 5-5 of Fig. 4.

Referring particularly to the accompanying drawings, my improved structure comprises a tube-like body 1, which for the greater portion of its length is of uniform diameter throughout, being exteriorly threaded at the inner end, or otherwise suitably formed for connection with a reservoir or liquid container, as 2, which will be more particularly referred to hereinafter. The outer end of the tube body is formed with an inturned lip 3, and at diametrically opposite points said lip is recessed to provide holding notches 4c. Said body is also .provided adjacent to said lip with an inturned bearing bead or rib 3 The brush used in conjunction with the body 1 is more particularly shown in Fig, 4 wherein, in the preferred form, said brush is of the type ordinarily used with mucilage bottles comprising a stem or handle portion 5 and bristles 6. The handle portion is of less length than of the usual brush and is approximately circular, though of less diameter than that of the tube body. Adjacent its connection with the bristles, the stem or handle portion 5 of the brush is flattened as at 7 and in the type designed for cooperation with the tube body described, such flattened portion has an edge width to snugly fit within the notches 4: of the tube body. The flattened portion of the body provides a wedge formation in plan so that when the stem or handle of the brush is forced into the notched end of the tube body it is snugly secured therein, the cooperation of the edges of the flattened portion of the handle with the notches 4 serving to prevent an independent rotary motion of the brush within the tube body. Such edges of the flattened portion are also engaged by bearing surfaces formed by the rib 3, whereby the brush stem is stayed and centered and held from tilting motion. When thus arranged, as will be plain from Fig. 1, a portion of the brush stem or handle projects beyond the outer end of the tube body, and by reason of its comparatively fiat formation provides between the sides of said flattened portion and the proximate edges of the lips 3, two delivery channels 7 through which the material is directed onto the sides of the stem or handle and so to the brush.

The tube body l'is through its threaded or other formation designed for detachable connection with the reservoir 2, and while contemplating any desired form of such container, that illustrated in the drawings is preferred. As shown the container is of the type having flexible side walls which on compression, tend to force the contained l1qu1d from the reservoir, as will be fullv understood without further detailed description.

With the parts connected, pressure upon the side walls of the reservoir will force the liquid through the tube body, out through the channels 7 and down the sides of the projecting portion of the stem or handle to the brush, permitting its ready application to the surface on which it is to be used.

The invention is particularly designed for use as a mucilage distributer, from which it will be readily understood that the mucilage in any quantity can be delivered to the brush for use. It is of course to be under- I stood that the invention is equally as serviceable with any liquid designed to be applied to a surface, as for example, in painting or varnishing, blacking, as for shoes or the like, and all and any similar uses.

It is well understood that fountain brushes are not new, and that it is admittedly old to supply material from a reservoir to a surface through the medium of such fountain brush. The disadvantages under which such devices, as heretofore known to me, labor, are, that in the case of most materials used with such fountain brushes, particularly mucilage and paint, a caking or hardening of the material at the outlet and the practical impossibility of a proper cleaning, render such devices useless in a short time. Furthermore, the impossibility in such known devices of the convenient renewal of the brush or the use of a brush of larger, smaller, or different form from the usual type materially reduces the scope of their usefulness. lVith the improved structure the brush as an entirety is readily and conveniently removed from the tube body, and when so removed an absolute and perfect cleansing of the parts is an extremely simple matter. Furthermore, the brush can be readily renewed or brushes of different sizes and types readily applied in an equally ob vious simple manner.

In connect-ion with the improvement it is noted that the material is delivered to the outer walls of the stem or handle and hence to the outer bristles of the brush, so that a saving of material is effected in avoiding a saturation of the brush bristles at least through the upper portion of the bristle body. In addition to the saving of material, this advantage prevents to an appreciable extent, the hardening of the brush as when used with paints or varnishes, as will be evident.

Any type of brush and any length of size of the stem or handle therefor, as well as the tube body is contemplated, so long as the parts cooperate as noted.

that is claimed is 1. In a fountain brush, the combination of a conveying tube, comprising a tube-like body provided at its discharge end with diametrically opposed notches and with bearing surfaces adjacent to said notches, and a brush having a stem disposed within said tube and provided with a flattened, wedgeshaped outer end engaging said notches and bearing portions.

2. In a fountain brush, the combination of a conveying tube comprising a tube-like body, a stem comprising a folded strip of material disposed within said body and having an expanded socketed end projecting through the discharge end of the body, and

a brush held in said expanded socketed end 1 of the stem, said discharge end of the body and expanded end of the stem having interengaging and spaced surfaces whereby the brush stem is frictionally held in said body and discharge passages are formed between the surfaces of the engaging portions.

3. A conveying tube for fountain brushes comprising a tube-like body formed at the discharge end with an inturned lip, said lip being formed wit-h diametrically opposed notches, and a brush having the stem or handle portion thereof flattened and wedgeshaped to frictionally engage said discharge end of the body and cooperate with the notches.

4:. I11 a fountain brush, the combination of a conveying tube comprising a tube-like body provided with an inturned flange at its discharge end, and a brush having a stem provided with a flattened wedge-shaped portion projecting through the discharge end of the body, said flanged end of the body and the flattened end of the stem being provided with diametrically opposed engaging surfaces, whereby the stem is frictionally held in the body, and formed at right angles to said engaging surfaces with passages for the flow of fluid outwardly along the projecting portion of the stem.

5. In a fountain brush, the combination of a conveying tube comprising a tube-like body, a brush having flat sides and provided with a stem fitted within said body and having flattened conducting surfaces leading to the fiat sides of the brush, said body and stem being formed with coacting contacting surfaces detachably holding the stem within the body and coacting spaced surfaces forming channels leading to said conducting surfaces.

6. In a fountain brush, the combination of a conveying tube comprising a tube-like body, a brush, a stem fitted within the tube and having its outer end forming a socket receiving said brush and provided with broad flat conducting surfaces leading thereto, the outer end of the tube and socketed end of the stem being provided with interengaging friction surfaces and spaced surfaces, the latter forming conducting channels leading from the tube to said conducting surfaces.

In testimony whereof I aflix my signature in presence of two witnesses.
