Referring more in detail to the drawings:

1 designates broadly a head for a fountain brush embodying the features of the present invention having a top 2 provided with a longitudinal boss portion 3 terminating in a cylindrical portion 4 extending outwardly from the depending sides or skirt 5 of the head. The

circular member 4 provides a water inlet 6 and is provided with internal threads 7 for attachment to a garden hose or the like (not shown). stiffening ribs 8 are provided on either side of the extension portion 4 of the inlet as illustrated in FIG. 3. It will be noted the sidewalls 5 of the head are tapered slightly outwardly forming 3. depending annular skirt.

The underneath side 9 of the top 2 is provided with a socket 19 here shown to be substantially square in crosssection and in which is mounted the head 11 by a cementitious material or the like of a shaft or post 12 having a cy indrical portion 13, a substantially square portion 14 and an offset cylindrical portion 15 provided with an annular groove 16 and being bifurcated as indicated at 17 for a purpose later discussed. The shaft 12 is mounted in the head so that it will be rigid therewith and not rotate.

Integrally secured with the underneath side 9 of the top 2 and spaced inwardly from the skirt 5 of the head is an annular flange 13 extending in substantially the same direction as the skirt. The cylindrical or neck member of the head has walls extending inwardly into the compartment 19 of the head as indicated at 29 and 21 (FIG. 3), the wall 2t) being slightly longer than the wall 21 and the end 22 of the flange 18 is secured to said wall and extends slightly past the same and is rounded and turned towards the inlet as indicated at 23 forming a shoulder 24. The other end of the flange 18 extends past the wall 21 as indicated at 25 forming a throat or passageway 26 for delivery of water therethrough as later shown.

An impeller 27 is provided for rotation on the shaft having a hub 28 formed integral therein and extending toward said head. A bearing sleeve 2% is mounted on the shaft 12 and is keyed to the impeller hub by notches 30 in the sleeve and ribs 31 on the hub 28. The impeller 27 includes a substantially thin plate or planar member 27' spaced from said head, and the sleeve 29 extends through the opening 32 therein and integrally formed with the sleeve bearing member is a gear 33.

The bearing sleeve 29 and gear 33 are substantially the length of the cylindrical portion 13 of the shaft and mounted on the substantially square portion 14 of the shaft is a sleeve member 34 having a substantially square inner surface 35 and a cylindrical portion 36. Formed integral with the sleeve member 34 is a head portion 34- having an arm 37 integral therewith and extending towards the depending skirt 5 of the head. Mounted on the top side of said arm is a short shaft 3%, to receive and rotatably mount thereon an idler gear 39 meshing with the gear 33 as illustrated in FIG. 4.

Mounted for rotation on the outside cylindrical surface of the sleeve member 34- is a plate member 40 slightly less in diameter than the depending skirt portion 5 of the head leaving a space 41 between the outer periphery 4-2 of the plate and the inside wall of the skirt 5 as best illustrated in FIG. 2. The plate member 40 has a circular flange 43 extending outwardly from the body portion of the plate and toward said head, also as illustrated in FIG. 3, and formed on the inner face 44 of the flange i3 are teeth 45 meshing with the teeth 46 on the idler gear 39. The flange 4.3 on the plate member 40 forms a recess therein for housing the idler gear 39 and arm 37, and also forms a compartment 47 for the water to pass from the impeller.

The impeller has spaced blades or bafiies 48 secured to the top side of the thin plate member having a plane surface 27' and curved slightly as indicated at 49 (FIG. 3) and extending inwardly from the outer periphery 50 thereof for rotating the impeller due to the force of water through the inlet 6.

The plate th is provided with a plurality of recesses 51 which may be in circumferential rows as indicated in FIG. 5 or may be staggered, as preferred. Mounted within these recesses are bristles 52. A retaining ring 53 is placed over the bifurcated end 17 of the shaft and engages the notch 16 to retain the plate 40, sleeve member 34- and impeller 27 in place in the housing of the head.

When the fountain brush is attached to a garden hose or the like (not shown) by the threaded connection 7 water will enter through the Water inlet portion 6 and pass through the cylindrical portion 54 thereof and will partially be deflected by the slanting wall 55 through the passageway 26 and engage the impeller blades 48 and rotate the same in a counter-clockwise direction, thus rotating the gear 33 and thereby rotating the idler gear 39. The upper side 39" of the gear 3? is provided with annular rib 4b which bears against the annular flange 18 and the face of the impeller plate 27' and acts as a spacer to align the teeth 46 of the gear 39' so that they will engage the teeth 45 of the bristle plate 4t), thereby rotating said plate in a clockwise direction. The water will pass from the impeller blades through the space 56 between said thin plate 27 and the inner wall of the depending flange 13 and be forced against the bristle plate 40 and pass outwardly through the space 41 between said skirt and the rotating bristle-bearing plate 459 to impinge against the vehicle being washed and thereby wetting the bristles when water passes from the head. Water will also fill the compartment 47 in which the arm 37 and the idler gear 3% are housed.

Formed integrally with the inside wall of the skirt are spaced lugs or stop members 57 against which the upper edge of the flange 43 of the plate may engage to prevent tipping of the plate during operation. The Walls of the neck of the inlet will also serve as a stop on that side of the head to prevent tipping.

It will be obvious from the foregoing that I have provided a fountain brush having an impeller mounted on a shaft rotating in one direction having a bristle-containing plate rotating in the opposite direction through a gear mechanism mounted on said shaft and wherein the water is impelled through the brush at the circumferential edge of the bristle-bearing plate. The ratio of rotation of the impeller to the bristle plate is approximately 6 to 1.

While I show the brush as made of synthetic resin, other materials may be utilized. A well-known synthetic gear material such as nylon may be used for the gears, arm and sleeves.

It is to be understood that while I have illustrated and described one form of my invention, it is not to be limited to the specific form or arrangement of parts herein described and shown except insofar as such limitations are included in the claims.
