' FOUNTAIN' BRUSH Filed oct. 21. 19:56

\ l V l Inventor: H562 PE/,C//E/VBHCA/ Patented July 25, 1939 UNITED STAT-'Es PATENT OFFICE Application omnial 21, 193s, serial No. 106,757 In Germany September 23, 1936 2 Claims. (Cl. 15-133) This invention relates to a fountain brush having a hollow handle which acts as reservoir from which the liquid to be applied automatically flows t'o the portion of the implement comprising the bristles, hairs, etc.

The invention covers a number of improvements of such brushes to prevent the handles thereof from getting wet and to avoid accidental dripping resulting therefrom. In brushes of known type these troubles are due to several coacting causes including the unsuitable construof, tion of known means for regulating the amount members for centering and securing the brush body, which are so constructed that reliable pack- 25 ing at the base of the brush body is insured.

Another obje'ct of the invention is to provide a drip catcher of simple make which while insuring proper admission of the liquid eliminates the danger of having the inlet openings clogged by a0 bristles,- etc.

Still other objects of the invention are mentioned in the specification below with reference to the accompanying drawing which illustrate by way of example one form of the invention-and in 35 which Figure l is an external View of a fountain brush according to the invention and Fig. 2 a

longitudinal section thereof on a plane disposed vertically to the plane of projection of Fig. 1.

Referring to the drawing, a hollow container I n for the liquid to be applied has screwed on its top a casing 2 serving as a handle and having a cylindrical chamber 3 which through anopening 4 is 'in communication with the inner space of the handle I below and through an opening 5 with the hollow neck 6 above leading to the brush body 30. In the cylindrical chamber 3 av cylindrical closing member 1 is inserted and provided with the wall openings 8 and 9-which register with the openings 4 and 5 of the casing 2. The mem- 50 ber 1 on the side facing the opening of the casing 2 is Vclosed by a wall I0 externally tted with a collar II and a pin I2 which passes through the cover I3 screwed into the casing 2 and carries at its free end the indicator I4 the point of which 2i moves over the scale I5 arranged on the outer wall of the casing 2. With its inner surface the cover I3 tightly presses a packing I6, preferably made of metal, against the casing 2 and posseses a collar I1 which fits into the collar II of the closing member 1. The collar I1 surrounds a 5 packing ring I8 which prevents liquid from entering theA bearing ofthe pin I2. On its outerV surfacel the cover I3 is providedin its center with a hexagon projection I9 for securing the cover I3 by means of a suitable wrench. On the edge 10 of the cover I3 a collar 2l) is positioned which is cut out within range of the point of the indicator I4 at 2I and limits the adjusting motion of the indicator. The collar serves for receiving a `slip-on closing cap 22 connected therewith by a l5 joint 23.

When in closed position, the cap 22 covers the indicator I4 so as to render visible only the point thereof, and the user can therefore control the adjustment of the device at any time without 20 risking accidental displacement of the indicator' during handling of the brush. In the construction shown the volume adjusting device can be inserted in the brush without soldering and easily taken apart for replacement of the packings if re- 25 quired. The packings I6 and I8 may be combined to form a single packing ring. i,

The neck 6 of the brush has a thread /24 at its upper portion for screwing on the brush carrier 25 in which a packing ring 26 is arranged. The 30 brush carrier 25 possesses on opposite sides plane surfaces 21 to facilitate attachment of the brush carrier by means of a wrench of the usual kind. Furthermore, the brush carrier 25 is provided with a plate 28 threaded at its outer edge to re- 35 ceive a sleeve 29 for connecting the brush body 30 with the carrier 25. The brush body 30 is tted below with a metal collar 3I in the usual manner. The top of the sleeve 29 is bent at 32, I and the latter comprises Aa packing ring 33 which 40 abuts against the upper edge of the vcollar 3l when the brush body 39 is screwed on. Owing to the sleeve 29, the brush body 30 can be screwed onto the carrierj25 Without bringing the hands of the operator into contact with the bristles, 45 hairs, etc.

Between the base of the brush body 30 and the plate 28 of the carrier 25 a packing ring 34 is positioned for packing the brush body below. The brush body 30 is centered relative to the carrier 50 25 by means of its wooden core 35 provided with a bore and attached to the hollow pin 36 of the carrier 25, the core consisting, as a rule, of hardwood. To prevent the brush body 30 from sticking-to the pin. Vthe core 35 has a metal lin- 55 ing 31 and the adjacent surfaces ofthe core 35 and of 'the pin 36 are slightly conical.

In this way good packing of the brush at the base thereof is insured and soiling'of the handle by dripping liquid prevented.- Furthermore, the brush body 30 can be screwed on and removed again without requiring the bristles to be touched by hand. Above the fastening sleeve 29 a drip catcher 38 is provided and rests with its base 39 on the bent end 32 of the sleeve. The inner wall 40 of the drip catcher 38, which surrounds the annular collecting space 4I, is bent to form a ring 42 closely adjacent to the bristles of the body 30.

'The bend 43 between the inner wall 4l! and the ring 42 is cut al1 around except for some narrow strips which keep the ring 42 at a distance from the wall 40. Between the ring 42 and the inner wall 40 an annular passage 44 is thus produced which cannot be blocked by bristles even when the brush is pressed against thesurface to be Worked, and liquid can therefore safely drop into the catcher 38. The new construction makes it possible to produce a drip catcher with an annular passage without any soldering, simply by bending a piece of sheet metal.

'I'he construction described eliminates the danger of wetting the brush, since the user can easily control and adjust the supply of liquid and because the adjusting means and the fastening point of the brush body are reliably packed and any excess of liquid can safely ow into the drip catcher.

The invention is not limited of course to the details of construction shown and described.

I claim:

1. A fountain brush, comprising a. container having a comparatively large diameter, a hollow neck body, of a smaller diameter which is fastened thereon and serves as a handle, said neck body comprising an enlarged casing portion hafing an outlet end, a regulating device for the con trol of fluid passage within said casing portion and a tubular portion of smaller diameter projecting from said outlet end, a brush carrier plate having a central fluid passage opening formed therein, said plate being detachably mounted on said tubular portion and having threads formed thereon, a sleeve screwed on said brush carrier 1;plate, one end of said sleeve having threads formed therein, an inwardly projecting iiange upon the opposite end of said sleeve, a brush body having a central fluid passage opening formed therein, an externally projecting base connected with said brush body, the inwardly projecting l ilange of said sleeve detachably clamping said brush body with its projecting base to said brush lcarrier plate.

2. A fountain brush, comprising a container of a relatively large diameter, ra hollow neck body fastened thereon, a regulating device forv the control of a fluid passage, said device being situated within said neck body, a brush having a central fluid passage opening formed therein, said brush being detachably secured to said neck body. bristles carried by said brush, and a drip catcher enclosing said brush near the inner end of its iiuid passage opening, said drip catcher consisting of sheet metal and having an inner axially disposed annular inlet passage formed therein, said passage having openings at its base, and an outer annular catch container surrounding said axially disposed inlet passage, said catch container having a radially disposed passage formed therein which is in communication with the brush bristles.
