It is desirable for maximum versatility of such a brush that means be provided for selectively discharging water from the brush head in either a jet stream or a diffused spray, the latter being primarily used during the washing operation and the former being used for rinsing.

Also where the brush has an oblong shape it is generally mounted on the handle in a crosswise position. This position is, of course, satisfactory where the brush is moved in a direction longitudinally of the handle during the washing operation. However, it is frequently desirable from the standpoint of comfort or better scrubbing action to move the handle from side to side in a wand-waving motion. In such an instance an oblong brush is, of course, more effective when it is positioned in alignment with or parallel to the handle. It is thus desirable that an oblong brush be adjustable between different angular positions relative to the longitudinal axis of the handle.

It is also desirable that such angular adjustment be combined with the aforementioned selective water discharge in either a jet or spray pattern.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a fountain brush with an oblong brush journaled on an elongated handle for selective adjustment of the brush between a position lying in general alignment with the handle and a position perpendicular to the handle.

Another object of the invention is to provide a fountaintype brush with a valving means for selectively discharging water in a jet stream or a diffused spray.

With these and other objects in view the invention broadly comprises an oblong brush mounted at one end of an elongated tubular handle for rotation on an axis generally perpendicular to the handle between positions lying in alignment with and crosswise to the handle and the mounting including a valving means for allowing the water to be discharged from the brush in a jet stream or a spray diffused among the brush bristles.

FIG. 6 is similar to FIG. 5 but with the brush in parallel position as in FIG. 3.

FIG. 7 is similar to FIG. 5 but with the brush rotated 180".

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now more particularly to the drawings reference numerals will be used to denote like parts or structural features in the different views. A tubular handle 10 has a suitable coupling (not shown) at one end for connection to a garden hose or other source of water under pressure. The handle may also incorporate some means for selectively metering a cleansing agent into the stream of water flowing therethrough.

The brush head is denoted generally by the number 11 and comprises a coupling member 12 and a brush 14. The coupling 12 has an integral sleeve 15 into which the end of handle 10 is threaded or press fit as shown in FIG. 4. Sleeve 15 connects at an angle with a disk 16 which has a downwardly opening circular peripheral groove 17. A pocket 18 is formed in the disk 16 opening within the sleeve 15 and this pocket has a narrow notched opening in its bottom forming a nozzle or jet orifice 19 which is directed downwardly and inwardly toward the axis of disk 16.

The inner side of groove 17 is formed by the circular wall 20. Within the wall 20 and spaced about the center axis thereof are the nozzle 19 and three circular downwardly opening cups 21. Cups 21 and nozzle 19 are spaced equidistantly degrees apart. Disk 16 has an extension 22 adjacent to sleeve 15 which journals a slidable latch member 24.

The brush 14 has an oblong back 28 which tapers toward the ends. Member 28 has a marginal depending flange 29 and a plurality of downwardly opening sockets 30 cover all but the central portion of back 28, each socket securely holding a bundle 31 of brush bristles.

The central portion of the back 28 has an upstanding circular flange 32 adapted to fit within the groove 17. The flange 32 is stepped in cross section to seat a sealing ring 34. An aperture 35 is provided in the back at the center axis of flange 32. A circular boss 36 depends from back 28 concentric with aperture 35. Washer 37 rests against the bottom of boss 36 and a machine screw 38 extends upwardly through washer 37 and aperture 35 with its end 39 threaded into disk 16 to secure brush 14 to the coupling member 12.

Within the flange 32 the brush back 28 is provided with a relatively large opening 40 adapted to align with the opening 19 in the pocket 18 when the brush is in the positions shown in FIGS. 4 and 5 of the drawings. There are also four smaller openings 41 in the back 28 within flange 32. These openings are spaced intermediate the intersection of the longitudinal and transverse axes of the brush so as to be offset with respect to cups 21 when the brush and coupling are assembled and when the brush is positioned either parallel or perpendicular to handle 10.

Four upwardly opening

sockets

44, 45, 46 and 47 are provided in the back 28 and spaced equidistantly about the outside of flange 32. These are adapted to receive the end of the latch member 24 to lock the brush 14 against rotation about the axis of screw 38. The latch member 24 is seated in socket 45 when the brush head is in this condition.

When the brush 14 is rotated degrees from the position shown in FIG. 6 so that the latch member 24 is seated in socket 47, the water flow will, of course, be

the same as just described and the brush will be parallel to handle 10 so the condition is really identical to the second condition.

FIG. 7 shows a third condition of the brush head with the brush 14 again perpendicular to the handle 10 and with latch 24 seated in socket 44. Here, however, the opening 40 is diametrically across from jet orifice 19 and again covered by one of the cups 21 so that the water will still flow through openings 41.

The brush is a fountain spray brush in either the second or third conditions, the only difference being the position of the brush relative to the handle. The purpose of the adjustability is that some users find the use of the brush more convenient such as on an automobile when the brush is in one position and on a house when in another position.

Latch 24 is preferably held in its locking position in one of the sockets 44-47 by a spring means (not shown) and this may include a ball and detent or a rounded end on the latch which seats in the sockets and which will slip out of the sockets when strong turning pressure is applied to the brush whereby the brush may be forcibly moved between various positions without actually lifting the handle of the latch.

The head 11 is in assembled conditions in FIGS. 1 to 4. It will be understood that while coupling member 12 is fixedly mounted on handle 10 the brush 14 is adjustable to various positions about the axis of screw 38. There are four positions in which the brush is locked in position.

In the positions shown in FIGS. 1, 2, 4 and the brush is in a fountain jet condition. The water from the source flows through handle which preferably has a selectively communicable soap compartment therein and then through sleeve 15 and pocket 18 and opening 19 directly through the large opening 14 in the back 28. The area below the opening 40 and surrounding the screw 38 is open and devoid of bristle bunches 31 so that when the brush is in this condition a stream of water jets directly from opening 40 through the brush without engaging the bristles. The brush 14 is locked in this condition by latch member 24 engaging in the socket 46. Generally, the brush is used in this condition for rapid rinsing of an area that has been previously scrubbed by the brush.

A second condition of the brush head is shown in FIGS. 3 and 6. Here the brush 14 is parallel to and aligned with handle 10 rather than perpendicular thereto as in the fountain jet condition just discussed. In this position one of the cups 21 will be covering and closing the opening 40. Accordingly, water emanating from the jet orifice 19 will flow over the back 28 within the flange 32 and downwardly through the small opening 41 and onto the bristles 31 therebelow.
