When the wrench is engaged with the head of rod 50 and is turned, the rod will turn to connect or disconnect the ball parts.
In FIG. 7 is shown tool 75. This tool has a generally V-shaped body formed from a strip of spring steel, springy plastic or other material. The tool has two ilat legs llt), 111 haring outwardly from the apex M2 of the tool. At the free ends of the legs are two prongs 114 which respectively engage in diametraliy opposed holes 70, '798, 7%', 74D, 932, 84a in any of the hemispherical Weights. The legs are biased outwardly due to the springiness of the tooi body and are normally spaced apart a distance greater than the spacing of the most widely To` engage in holes 7d', 74h the legs must be pressed manually inward toward each other. To engage in opposingy holes @da or 8411 the legs must be compressed even further. When the legs are released, the spring tension at apex 112 will force the prongs into the opposing holes in the hemispherical weight to be removed from the ball or inserted therein. A supplementary, arcuate, leaf spring HS is secured to intermeciate points of legs H9, 111 by rivets 116 and increases the outward spring bias of the legs llt).
To adjust the weight of the ball, two, four or six weights will be removed or inserted from the ball parts. The weights must be removed in pairs to keep the remaining parts of the bail assembly in balance. If it is found desirable to balance the weight of the assembled ball parts with respect to the diameters taken through each of the nger holes 32 in ball part 12E, then another group of similar finger holes 32' may be provided in ball part 12b located between member 46 and recess 40. Each one of holes 32' will be diametrically aligned with a corresponding one of holes 32, when the ball parte are intertted and secured together.
In order to insure proper alignment of the finger holes in the two ball parts, index marks M, M' may be provided on the outer sides of the respective ball parts. When these marks line up as indicated in FIG. 2, then the holes 32 are correctly aligned with holes 32'.
The invent-ion has been described with particular reference to a bowling ball, but it will be apparent that it is applicable to any ball structure where a balanced ball of adjustable weight and mass is required. While the invention is particularly applicable to balls used in playing various games, `it is also applicable to balls used in weight lifting, shot putting, and the like, It .is also applicable to balls used in other applications than sports and games. The weights, can, of course, have any desired magnitudes. in one practical embodiment a bowling ball was constructed with an outside diameter of about eight and one-half inches. The individual weights were about one pound each. The ball can, of course, be made in other sizes.
While l have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and that various changes and modifications may be made within the scope ot the invention as defined in the appended claims.
Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:
