     This application is co-pending with Ser. No. 08/140,745 of the same applicant titled Hand Held Golf Ball Washer, filed Oct. 22, 1993, now U.S. Pat. No. 5,400,455. 
     BACKGROUND OF THE INVENTION 
     This invention pertains to golf ball washing devices and in particular to hand held golf ball washers. 
     In the course of the playing of the game of golf, it is inevitable that the golf ball becomes grass-stained and caked with mud. In order to make the driven ball easier to find and to ensure that its flight characteristics are not affected by the presence of mud or other foreign material upon the surface of the ball, it is useful to clean the surface of the golf ball to remove foreign material and Grass or other stains. 
     Available golf ball washers which are known are predominantly nonportable and nonmotorized, such as illustrated in Burkholder, U.S. Pat. No. 3,678,526; Procario, U.S. Pat. No. 2,744,274; and Brillhart, U.S. Pat. No. 2,031,633. A manually driven, portable golf ball washer is disclosed in McConnell, U.S. Pat. No. 3,508,016. 
     A motorized portable golf ball washer is shown in U.S. Pat. No. 4,381,574 to Benkovsky which features a foam lined cup which rotates about the ball while held in place by a liner/retainer which resists turning of the ball. In order to wash the entire ball, it would be necessary to move the ball during the washing operation to another orientation in the cup so that the portion of the ball&#39;s surface which had been retained by the liner would then be washed. 
     Ingram et al., U.S. Pat. No. 4,084,287, teaches a hand operated portable ball cleaner which provides a toroidal sponge inside stiff rings which operates upon the golf ball&#39;s surface as the ball is manipulated by the user.

     DETAILED DESCRIPTION OF THE INVENTION 
     The preferred embodiment of the present invention 2 is shown in perspective in FIG. 1. An elongate case 4 is provided with a front wall 6 having an opening 42 from which removable cover 10 is retractable. Cover 10 is removably mounted to front wall 6 by bayonet means provided therefor, comprising legs 11 which may be inserted in notches 13 of opening 42 such that when cover is rotated, legs 11 will retain cover 10 to case 4. Other attachment means may be employed to retain cover 10 to opening 42 in front wall 6. A push button normally open switch 20 is mounted upon case 4 at a convenient location thereon. It is to be understood that case 4 may be of cylindrical, hemispherical, rectangular, or other desirable shape. 
     Referring to FIGS. 2 and 3, it can be visualized that case 4 is provided with a first chamber 12 and a second chamber 14 therein, the first chamber 12 being a ball receiving chamber which is located within first end 8 of case 4. In the preferred embodiment, first chamber 12 is partially cylindrical in shape. Opening 42 of front wall 6 of case 4 is generally circular, embodying a first end of a cylindrical chamber wall segment 24 which is enclosed at its lower end by dome section 28. Because cover 10 is generally dome shaped, when cover 10 is placed over opening 42, chamber 12 comprises a cylindrical enclosure with domed ends. 
     Rib 19 is provided within chamber 14 as needed to provide structural stability to case 4. Second chamber 14 is provided to receive a dry cell power supply 16 electrically connected to direct current motor 18 through switch 20 such that power supply 16 powers motor 18 when switch 20 is depressed. In the preferred embodiment, power supply 16 comprises a 9 VDC dry cell. Driven shaft 26 of motor 18 is rotated at a speed in the range of 50 to 300 revolutions per minute (RPM), preferably approximately 125 RPM. In the preferred embodiment, motor 18 is a d-c motor which operates on 6.0-12.0 VDC power at 4100-8300 RPM under load. 
     First chamber 12 and second chamber 14 are separated by curved watertight wall 30 through which passes driven shaft 26. Driven shaft 26 is mounted to rotor brush member 32 such that rotor brush member 32 will rotate on an axis generally coincident with the axis of case 4. Rotor brush member 32 comprises a curved, U-shaped segment having a spine 33 which is provided with bristles 34 which inwardly depend from spine 33 to engage the surface of a golf ball 1 placed within first chamber 12, such that inwardly depending ends 35 of bristles 34 will contact golf ball 1. It can be understood that the depending ends 35 of bristles 34 generally define a segment of a circle with a radius generally equal to the radius of a golf ball. 
     Static brush member 45 is fixed to inside surface 7 of distal wall 9 of chamber 12. Static brush member 45 approximates a T-shape and comprises first and second segments 44 and 46 respectively which are curved to conform to the shape of inside surface 7 of chamber 12 and are fixed thereto, wherein second segment 46 joins first segment 44 generally at its midpoint in orthogonal fashion at the point of joinder. First segment 44 is fixed to dome section 28 spaced apart from the equatorial line thereof a small amount in the preferred embodiment. First segment 44 defines a plane which is generally perpendicular to the axis of driven shaft 26. Second segment 46 is fixed to inside surface 7 such that it is fixed to dome section 28 and extends along cylindrical wall segment 24 and opposes rotor brush member 32. The plane defined by second segment 46 is generally parallel to the axis of driven shaft 26. Static brush member 45 is provided with inwardly depending bristles 48 which will engage a golf ball 1 when it is placed in chamber 12 with cover 10 disposed over opening 42. Static brush member 45 defines a spherical segment with a radius approximately equal to the radius of a golf ball. 
     In the preferred embodiment, rotor brush member 32 and static brush member 45 are constructed by winding bristles about a metal twisted spine thereby fashioning spiral flighting of bristles upon the curved spine. Bristles 34 and 48 of brush members 32 and 45 respectively are trimmed to a length of approximately 1/8&#34;. 
     Detergent solution 5 is introduced into first chamber 12 in sufficient quantity to assist cleaning of golf ball 1 by rotor brush member 32 and static brush member 45. 
     Clip 60 is provided by pivotable attachment means 62 upon case 4 to provide means for attachment of invention 2 to the user&#39;s golf bag, golf cart, or clothing. 
     In order to provide a pleasing appearance for invention 2, cover 10 is preferably molded of white polymer material with dimples 15 formed in the outside face 17 thereof, such that cover 10 resembles an oversize golf ball section. 
     OPERATION OF THE INVENTION 
     It can be readily seen that cover 10 may be removed from case 4 and a golf ball 1 inserted through opening 42 therein. A small amount of detergent solution 5 may be placed into first chamber 12 and cover 10 replaced into opening 42 to close first chamber 12. Push button switch 20 may be depressed by the user which causes motor 18 to be energized thereby driving shaft 26 to cause rotation of rotor brush member 32 against ball 1 which also is scrubbed against static brush member 45 as rotor brush member 32 turns. After sufficient operation of motor 18, the push button 20 is released and cover 10 is removed such that golf ball 1, now clean, may be removed and used in the golf game.
