Description

Oct. 31, 1961 B. l. HOFFECKER PORTABLE ROTARY GOLF BALL CLEANER Filed Feb. 18, 1959 IN VEN TOR. BEECHER I. HOFFECKER A m A w mwx ATTORNEY United ram This invention relates to the cleaning of gold balls. More particularly, it relates to an apparatus adapted to be easily carried by a golfer, caddy, or other person, whereby golf balls may be quickly and easily cleaned.

It is well known that a golf ball rapidly becomes discolored and soiled during use. Quite commonly, the ball becomes grass stained or muddied. As is well known, many golf courses provide golf ball cleaning stands on their premises. However, it is often the case, depending on the particular golf course considered, that such stands may be very infrequent, being provided only at the first tee or at several tees throughout the course. In addition, it often happens that even such stands as are provided are not properly maintained, so that their cleaning function is impaired. Because of the great number of golfers using any particular stand, even when careful maintenance is attempted, the water in the cleaning mechanism is often rapidly dirtied or exhausted.

Furthermore, even if cleaning stands are plentiful on the course and are carefully maintained, it frequently happens that one stroke of the ball will result in soiling it s'ulficiently to lower its usefulness, so that even the existence of a cleaner at the next tee does not fully serve the interests of the golfer. As a result, the golfer either plays one or more strokes with a dirty ball, which results in distracting his attention, possibly afiecting the flight or roll of the ball, and increasing the possibility of a lost ball, or he switches to another ball. This latter course is inconvenient. It is believed that portable cleaners have been proposed heretofore, but the portable rotary golf ball cleaner of this invention is an improvement thereon, obviating many of the former difliculties.

It is an object of this invention to provide a portable golf ball cleaner.

It is an object of this invention to provide a small, light, rotary, cleaner for golf balls.

It is another object of this invention to provide a portable cleaner forgolf balls, which cleans the balls by a rotary motion imparted by a hand crank.

Yet another object of this invention is to provide a portable rotary golf ball cleaner comprising a ball clip, manual rotating means, spherically disposed sponge means, all contained within an openable case.

Other objects and aims of this invention are made apparent in the following specification and claims.

The invention is best understood in connection with the accompanying drawings, in which like numerals refer to like parts, and in which:

FIGURE 1 is a top view of the cleaner,

FIGURE 2 is an elevation view, partially in crosssection, taken along line 2-2 of FIGURE 1, and

FIGURE 3 is an elevation view, partially in crosssection, taken along line 22 of FIGURE 1, wherein the ball holding means has been rotated 90 degrees from the position shown in FIGURE 2.

The golf ball cleaner, generally designated at 10, is of a generally spherical shape. The outer covering or case of the cleaner consists of an upper case 15 and a lower case 16. Each of these case sections is generally hemispherical in shape. The exceptions to this general configuration are explained below.

The two case sections, 15 and 16, are hinged together by hinge 14. A latching means is provided to hold the two case sections firmly together when desired. In the F ice illustrated embodiment, this latching means consists of a hook portion 15A on the upper case 15 at a point along the closing line diametrically opposite the hinge 14, and a lug 16A on the lower case 16 along the closing line at a point diametrically opposite hinge 14. When the case sections are pivoted together around hinge 14, lug 16A engages hook 15A and is removably held there by the elastic or spring action of the case material.

The interior of each case section is lined with a resilient cleaning material. The lower case section 16 is lined with a resilient cleaning material 24 which in itself has a hemispherical shape following the general configuration of the case section. The upper case section 15 has a similar lining of cleaning material 23 which also follows its configuration, with an exception described below. In the embodiment illustrated, this resilient cleaning material consists of a sponge of relatively fine grain. In a preferred type of sponge is one made of synthetic plastic. The sponge is preferably removable from the casing for a replacement when worn.

The golf ball cleaner is equipped with holding means for the golf ball to be cleaned. This means comprises a clip 22 which grips the golf ball firmly when the ball is forced into the clip. The clip is so configured that it deforms slightly when the golf ball is forced into it and the ball is held by reason of the clips elasticity which tends to press tightly against the balls surface.

The clip 22 is preferably made of a thin strip of metal, preferably a non-corrosive metal such as stainlesssteel, which has been bent into a loop. For the best gripping action, the loop defined by clip 22 would not be quite circular, so that when ball 25 is forced into it, the loop is slightly deformed into a circular shape and thus grips the ball tightly. It is understood that even if the clip 22 is not non-circular, a gripping effect is obtained merely by having the internal diameter of the clip equal the external diameter of the golf ball. Since American golf balls are of standard dimensions, the cleaner would be applicable to all such balls.

Means for rotating the clip, and its contained golf ball, are provided. These means comprise a turning block 153 on the top of upper case section 15, which contains the rotating mechanism. The rotating mechanism includes a holder shaft 21 extending vertically through the turning block 15B. A spur gear 20 is provided at the upper end of shaft 21.

The spur gear 20 meshes with a driving gear 17, which is also mounted in the turning block 15B, as shown. The driving gear -17 is rotatably mounted on turning block 15 by means of pin 19. A crank handle 17A is attached to driving gear 17. In the illustrated embodiment, the pin 19 is shown extending through gear 17 and the end of crank 17A.

In use, the resilient cleaning material inside the casings are wet with water and a cleaning agent, such as a good detergent, as is well known. Of course, it is within the scope of this invention to wet the resilient cleaning material 23, 24 with any cleaning agent, whether containing water or not. Usually, a non-foaming detergent, as is commercially available, mixed with water, is satisfactory. The golf ball to be cleaned is inserted into the clip 22, and the golf ball cleaner is closed, and latched into position by the interaction of latch members 15A and 16A. The crank handle 17A is then rotated, which in turn spins the ball inside the cleaner and scrubs its surface clean. After opening the unit, the golf ball is removed and is ready for use. Once having added the cleaning agent to the sponge or other resilient cleaning material it may be used to clean many golf balls before renewal or rinsing is required.

By providing a gear train as shown as part of the rotating means, the torque exerted on the ball may be increased, so that a ball which may be coated with gummy substances can be rotated with a minimum amount of manual effort. In addition, the use of a reduction gear, as shown in the drawings, permits closer tolerances of the sponge against the ball without requiring undue manual effort. The gears may of course be made of any suitable material, such as stamped metal or plastic fiber. It is also possible to eliminate the gear train and rotate shaft 21 directly from a crank. Such an embodiment would be operative, although the gear drive is preferred for the reasons given above.

The crank handle 17A may take many different forms within the scope of this invention. For example, it may be provided with :a fold-down grasping knob, instead of the raised grasping knob 1713. The provision of a folding knob would, of course, reduce the possibility of snagging.

The clip 22 is shown as a separate member from shaft 21, although it is possible to manufacture the clip and shaft as an integral unit. A preferred material for the casings '15 and 16 is molded plastic. As shown, the upper case is integral with its latch member 15A, its part of the hinge 14, and the turning lock 153. The lower case member 16 is integral with its latch member 16A and its part of the hinge 14. This structure is preferred, although any of the parts can be made integral or separate.

There are a great variety of suitable materials available both for the case and for the sponge or other resilient cleaning means. The Well known tough fine-grained plastic sponges are very satisfactory because of their good absorbency and their shape-retaining qualifies.

The unit herein described performs the functions of known golf ball cleaners, with the advantage of being relatively extremely small, light, andcompact, It may be carried in the users pocket or in a golf bag pouch. By providing cleaning surfaces bearing around the entire circumference of the golf ball, a much more efficient cleaning action is obtained than is nsuafly the case with known golf ball cleaners. Therefore, less motion is required to thoroughly clean the ball. Also, the holding means covers a very small area of the ball surface, thus permitting much better cleaning. The unit itself is attractive in appearance, being suggestive of the shape of a golf ball. Its exterior surface may of course be decorated so as to resemble a golf ball. Any known type of exterior attaching means may be provided if desired. Various structural modifications may be made without departing from the spirit of the invention. For example, bushings may be provided around the shafts or pins if desired.

The scope of this invention is to be determined by the appended claims and is not to be limited by the foregoing description and drawings, which are intended to be illustrative and not limiting.
