DISPENSING BRUSH Filed July .6, 1946 l k MA M IN VEN TOR. Hark doss Q/OZM lemma 5v Patented May 30, 1950 UNITED STATES PAENT 3 Claims.

This invention relates to brushes, and certain objects of the invention are to provide a brush having a compartment for liquid solutions such as soap or ammonia, and a compartment for Water which is in direct communication with the brush bristles, and controlled by valve action, the said valves allowing the desired percentage of the solution to be mixed with the water before entering the brush bristles.

Another object of the invention is to provide a means whereby the brush may be used with or without a running supply of water, positive valve control means for the solution, and means whereby the running water is supplied evenly and with reduced force to the water compartment.

Another object of the invention is to provide a rotary type control valve mounted in the handle of the brush and when operated, permits the water to pass through a tube and discharge from a jet, which causes a vacuum within the soap compartment, drawing the soap solution there" from and mixing the said solution with the water, and means whereby the mixture is delivered from the mixing chamber to the bristles.

With the above other objects will appear as the description progresses. The invention consists of the novel construction, adaptation, combination and arrangement of parts hereinafter described and claimed. These objects are accomplished by devices illustrated in the accompanying drawing; wherein:

Fig. l is a view in perspective of the assembled brush.

Fig. 2 is a view in longitudinal section taken on line 2--2 of Fig. 1.

Fig. 3 is a fragmentary view showing the valve in an enlarged section.

Fig. 4 is a sectional view of the vent valve taken on line 44 of Fig. 2.

Fig. 5 is a sectional view showing the valve taken on line 55 of Fig. 3.

Referring to the drawings, throughout which like reference numerals designate like parts, the brush I as a whole, comprises a cover 2, which is cast integral with a head portion 3 and contains a mixing chamber 4 and a solution chamher 5. A handle 5 is secured to an intermediate section I which is bolted to the head portion 3 by bolts 8. A disk or plate 9 is provided with a rim III, which contacts the underface of the cover plate 2 and is attached thereto by screws II.

The plate 9 is preferably made of plastic material and is drilled to receive the bristles l2 in the usual manner. The water is conveyed to the brush through a hose which is attached to a coupling I3 imbedded in the end of the handle, through which the water flows into the chamber M of the hollow handle 6. From this chamber the water flows through ports l5 and IS. The port It is formed in the side wall of a stem portion ll, of the valve and when the ports [5 and I6 are in alignment, the water flows through the ports and into an opening [8 extending longitudinally through a tube l9. As the water leaves the end portion through a restricted opening 20 of the tube IS, a partial vacuum is formed in the port 2! of a stem 22 screwed into the lower side of the tube it, which partial vacuum draws a prepared solution from the chamber 5 through the port 2!. The mixed solution enters the chamber 4, where it is distributed over the complete inner surface of the bottom wall of the chamber 4. Perforations 25 and 25 formed through the wall of the chamber 4 and through the plate 9 respectively allow the mixed solution to flow into the bristles of the brush while being used.

The water stream is controlled by the valve which has the stem l1 revolvabl mounted into a boss 26 carried by and located centrally of the member I. The valve stem i1 protrudes from a disk 21, which is circular and is provided with a rim 28. This rim extends beyond the periphery of the brush handle and can be operated by revolving the said disk to the right or left, a onequarter turn, the movement of which is controlled by bolts 8, extending through slots 3% in the disk.

By revolving the disk or valve to the right, the ports l5 and it are aligned, permitting the water to flow into the stem H. To control the flow, the valve may be turned to an adjusted position in which the openings 55 and I6 allow the amount of water required to flow to the brush, or it may be entirely shut ofi by revolving the valve in the reverse direction until the bolts 8 contact the ends SI of the arcuate slots 30. Gaskets 32 are placed on both sides of the disk and rest in recesses 33 formed in the contacting end walls 34 and 35 of the head 3 and the handle section I, thus preventing the water from leaking past the disk.

To assemble these numbers the disc 21 is placed between the head 3 and the handle section I with its valve stem I! fitting into the boss or socket 26 and the tube I9 extending longitudinally through the chamber 5. Nuts 36 are cast in the head portion 34. The heads 34 and 35 are provided with openings 31 and 38 to receive the bolts 8. Before the handle 6 is screwed at 29 to the member 1, the bolts 8 are passed through the openings 31 and 38 and by applying a screw driver to the slots in the heads of the screws, they are threaded into the nuts.

A filler plug 39 is provided at the underside of the member 3 and normally closes an opening through which a desired solution may be poured to fill the chamber 5. To permit the solution to be removed from the chamber 5, it is necessary to vent the chamber.

To accomplish this, I have provided a spring held ball 40, which seals a port 4!. When a partial vacuum is created in the chamber 5, the spring allows the ball 40 to rise to an open position out of closing relation to the port M and air passes through ports ll and 42 into the chamber 5.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States is:

1. A fountain brush comprising a cover plate, a hollow head upon said plate having a portion extending rearwardly from the plate and formed with an opening at its rear end, a partition extending transversely in said head and dividing the head into front and rear chambers, the rear chamber being formed with a filling opening, said plate having a portion constituting a bottom wall for the front chamber formed with outlet openings, a perforated backing plate carrying tufts of bristles and formed with outlet openings between the tufts, a flange about the margin of said backing plate secured to the cover plate and holding the backing plate spaced from the cover plate, a hollow handle having a water inlet at its rear end and having its front end formed with a socket aligned with the opening at the rear end of said head, a valve-controlled tube extending longitudinally through the rear chamber and having its rear portion mounted in the aligned opening and socket, said tube and socket formed with openings for flow of water from the handle into the rear of said tube, said tube having its front end portion passing through the partition into the front chamber, and a tubular stem disposed vertically in the front end portion of the rear chamber under said tube and having its upper end mounted in an opening formed in the tube and communicating with the bore of the tube.
