15 Claims. (Cl. 15-21) This invention relates to a ball cleaner and more specifically relates to a vertically reciprocable golf ball cleaning device which immerses and scrubs all portions of the ball.

An object o-f my invention is to provide an improved ball cleaning device of relatively simple and inexpensive construction and operation which scrubs all portions of the ball surface, including the indents therein, by moving the ball in a unique and improved manner against scrubbing means.

Another object of my invention is the provision of a ball cleaning device of the class described wherein the golf ball is revolved about its own center against surface scrubbing means and in addition is moved in a spiralling orbital motion against the scrubbing means for cleansing the ball and for rotating the same and thereby causing all portions of the ball surface to engage the scrubbing means.

Still another object of my invention is to provide a ball cleaning device of the class described which, when not in use, is substantially sealed to restrict entrance of rain Water and foreign material and t restrict evaporation of the ball-cleaning luid therein and which will thereby be easily maintained for efficient operation.

A further object of my invention is the provision of a golf ball cleaner of the class described which at all times contines a ball placed therein so that the ball will not pop out or be irnpelled out in an uncontrolled manner and which is constructed so that the ball must be lifted out.

These and other objects and advantages of my invention will more fully appear from the following description made in connection with the accompanying drawings wherein like reference characters refer to the same or similar parts throughout the several views and in which:

Fig. 1 is a sectional elevation view taken longitudinally through the device substantially at 1-1 as indicated in Fig. 2.

Fig. 2 is a transverse section View of the device taken on a line substantially at 2 2 of Fig. l and being partly in top elevation;

Fig. 3 is a section View of the device taken substantially `at 3 3 of Fig. 1;

Fig. 4 is a section view taken substantially at 4-4 of Fig. l;

Fig. 5 is a section view taken substantially at 5-5 of Fig. l;

Fig. 6 is a detail top plan view of one of the brushes constituting the scrubbing means of the device;

Fig. 7 is a front elevation detail view of the backing of the brush shown in Fig. 6 but having the bristles removed for sake of clarity;

Fig. 8 is a transverse sectional View of an alternative form of the ball cleaning device and being a similar view to Fig. 3 but at a reduced scale with respect thereto; and

Fig. 9 is a view similar to Fig. 7 of the brush backing dates Patent utilized in the alternative form of the invention shown in Fig. 8.

The ballvl cleaning device which is designated in general by numeral 15 is provided with a housing or tank 16. Tank 16 is provided with an upstanding substantial 1y circular side Wall 1'7 to which is secured a cover plate 18 and to which is also secured, and in the form shown, has integrally thereof, an elongated cylindrical guiding member 19, the interior of which communicates with the interior of tank 16. A removable plug 19a is threadedly secured in the lower end portion of the sleeve 19. An upstanding and substantially annular support wall 20 is formed integrally of tank 16 and is disposed inwardly of the outer wall 17 to define a liquid storage chamber 21 therebetween. Wall 20 is provided with a number of apertures 22 which provide liquid communication therethrough. Wall 2t) is also provided with a pair of inwardly extending lips 23 or abutments which, in the form shown, extend partially around wall 20 in diametrically opposed relation to each other. A ledge 24 is formed in the tank wall inwardly of and adjacent to the bottom portion of the inner wall 20 land has a groove or channel 25 formed therein.

Cover 18 is removably aiiixed to the side wall 17 of tank 16 by any suitable means such as screws 26. Cover 18 is provided with an enlarged opening disposed centrally thereof and at the peripheral edge of said opening is provided with an annular seat 27. A pair of inwardly opening recesses or channels 28 are cut in the annular seat 27 and top 18 to provide guide or camming bearings.

An elongated and rigid ball-carrying element designated in general by numeral 29 is mounted in tank 16 in a generally upright position and constitutes a paddle or plunger. Paddle 29 is of generally rectangular cross section and is twisted about an axis extending longitudinally therethrough so as to dispose the lateral side portions thereof helically about said axis. The lateral side portions of paddle 29 extend into the channels 28 of cover 18 to be guided thereby. The marginal portion of the paddle provides a camming surface which engages the bearings of top 18 provided by channels 28.

' Cover or closure member 30 is aiixed to or formed integrally of paddle 29 at its upper end portion and is of substantially annular shape so as to substantially sealinglyengage the annular seat 27 of top 18. A handle 31 is rotatably mounted on paddle 29 in alignment with said axis extending longitudinally therethrough.

` Paddle 29 is vertically shiftable in tank 16 and through the top 18 thereof and in the direction of the longitudinal rotation axis thereof and is provided with means for guiding the same in vertical shifting movement. Such means include `an elongated shaft 32 which is affixed to paddle 29 and extends downwardly therefrom into the tubular portion 19 of tank 16. A bearing 33 is ailixed to shaft 32 and is slidably 4and rotatably engaged with the interior of the tubular sleeve portion 19 of tank 16. Shaft 32 is twisted about the longitudinal yaxis thereof which is Valigned with the axis of paddle 29 so as to helicailly dispose the lateral side portions thereof and to provide camming surfaces for rotating the sha-ft and paddle. A cam bearing 34 is affixed to tank 16 as by set screws 34a and slidably engages the twisted or helically disposed fcamming surfaces of shaft 32. A stop member 35 is aixed to shaft 32 and is vertically shiftable therewith into engagement with bearing 34 which provides an abutment `for restricting the upward movement of paddle 29 and shatft 32.

Paddle 29 is provided with an enlarged oblong opening 36 therein adjacent the lower end portion thereof which is disposed diagonally or obliquely of the rotation axis of paddle 29 and of the direction of vertical movement thereof.. Opening 36 is of substantially larger size than the diameter of a golf ball and is adapted'to receive and carry such a ball therein. The end portions of the obliqudy disposed-oblong opening 36 are of such size that such a golf ball may lodge therein so as to be disposed. eontrically ofidie-faxis ofrotation of paddle 29.

Yieldable-Kscrubbing. means are providedin tank. 16.I

n, In operations. liquid cleaning agentsuchas water havingfa quantity ofdetergent therein will be inserted into the tankand the; 'liquid may circulate. through the tank and except that ,they are formed in short segments 1 therethrough as the paddle is shifted downwardly into the tank .and upwardly through the top thereof. As the paddle is shifted downwardly into the tank, the paddle is revolved and the 'ball will engage the scrubbing means and will thereupon shift into the upper portion of the obliquely disposed oblong opening 36 land be eccentrically disposed and revolved about the rotation axis of paddle 29. Action of thebrushes `against the ball will cause the same to be turned about its own center in several directions to cause all of the surface area of the ball to be engaged and scrubbed'by the bristles. Because the ball is eccentrically disposed relative to the paddle rotation-axis while being shifted downward, .substantially more pressure exerted-by the ball against-'certain portions of the brush than against the other-portions of the brush so as to cause the ball to be rotated in several directions as it is moved downwardly through a spirally orbital path. Theball willbe urged againstthe brushes with suflicient force so that thebristles thereof willeliiciently, clean the ball Isurface and the indentstherein. Whenthe paddle is again raised, the paddle will revolve, and the ball will be lodged eccentrically of thev paddle rotation axis in the lower end of the obliquelyy disposed. oblong opening. 36,v

Vbecause it will'be retained from vertical movement by the upper portion of the paddle andwill be restricted in movement transversely of the vertical travel thereof by the retainer adjacent seat27 of top 18.

When the b'all'has been cleaned and removed from the cleaning device the paddle will thereafter be shifted downwardlyv into the tank and`cover30, which is aixed to the paddle, will substantially sealingly engage the annularseat 2.7` of cover 18 and will thereby restrict entrance of rain water or foreign material into the tank. The liquid in the tank will thereby be maintained at its full strength and will not be dirtied or contaminated by naturalV causes.

Itwillbe seen that I'have provided an improved ball Cleaning device which may be inexpensively manufactured and maintained which scrubs all portions of a golf ball by whirling the sameeccentrically around `an axis and against scrubbingmeans which turns. theball'on its own center and'tliereby engages and'cleans all ofthe surface thereof including the indents therein.

It-should also-beapparent-that-I have provided a golf ball cleaning device which not only contines the ball thereinlso that the ball lwill not pop out or be compelled out inan-uncontrolledmanner, butewillalso substantially seal out rain and foreign material when the ball cleaningdevic'e is not-in yuse.

Itlwill, of course,.be understood that various changes may be made in the form, detail, arrangement and proportionfoflthe parts lwithoutdeparting from-the scope of-my invention which consists of the matter described herein:
