Toall whom it may concern:

Be it known that I, EUGENE A. SoHENoK, a citizen of the United States, residing at Kansas City, in the county of Wyandotte and State of Kansas, have invent ed new and useful Improvements in Bowling-Balls, of

Y which the following is a specification.

Myiiivention relates to improvements in bowling balls. I

My invention provides a bowling ball having peripheral holes for the insertion of the fingers, and finger holds intermediate said holes and adjustable to different positions at the convenience of the bowler.

. My invention provides further, adjustable means for counterbalancing the finger holds.

invention provides further, adjustable means for varying the center of gravity of a bowling ball so that the ball may be deflected in a curvilinear mannercorresponding to the English imparted to a billiard ball.

My invention provides further, a hollow bowling ball comprising two detachable hemispheres, 'th shell of the ball being provided with two holes for the insertion of the fingers and two finger holds. intermediate said holes and adjustable toward and from each other, and

adjustable means for counterbalancing the weight of the finger holds. a

Other novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings illustrating the invention-Figure 1 is a diametrical sectional view, on the dotted line ef of Fig. 4. Fig. 2 is a horizontal sectional view taken on the dotted 'line ab of Fig. 1.

Fig. 3 is a horizontal sectional View taken on the dotted line 0-0? of Fig. 1. Fig. 4 is a top view of the ball.

Similar characters of reference denote similar parts. In its preferable form, the bowling ball comprises a hollow sphere consisting of two

hollow hemispheres

1 and 2, the end of one hemisphere being externally screw threaded and fitted to the internally screw threaded adjacent end of the other hemisphere. The hemisphere l is provided with two peripheral finger holes 3 to receive the thumb and one of the other fingers of the bowler. Intermediate the holes 3 are two inwardly extending cuWed finger holds 4 and 5, the

inner ends of which are pivoted respectively to two finger hold'supports 6 and 7, secured by bolts 8 to the inner wall of the hemisphere 1. To the inner side of each finger hold 4 and 5 is pivotally connected the outer end of a screw threaded rod 9 the inner end of which is fitted to a screw. threaded hole provided in the adjacent end of a turn buckle 10, rotatively mounted on the two rods 9. The rods 9 are oppositely screw threaded so that by rotating the turn buckle 10 to and fro the finger holds 4 and 5 may be swung toward and from each other to positions suiting the convenience of the bowler. The supports 6 and 7 are provided each with two longitudinal slots 11 in each of which slots are screw threaded holes provided in the plates 17 and 18,

secured respectively by means of bolts 19, to the inner sides of the hemispheres l and 2 respectively.

20 denotes clamping nuts mounted two upon each bolt 19, the outenof said nuts resting against the inner side respectively, of the plates 17 and 18, the inner of said nuts 20 serving as lock nuts.

21 denotes two lock nuts mounted one upon each

stem

15 and 16, and bearing respectively upon the inner sides of the plates 17 and 18. By properly turning the'stems 15 and 16, the weights 13 and 14 may be radially adjusted to positions properly counterbalancing the finger holds 4 and 5. Intermediate the weights 13 and 14 and diametrically opposite the finger holds 4 and 5, is a radially adjustable Weight 22, provided with aradial screw threaded stem 23, rotatively fitted in a screw threaded hole provided in a plate 24, secured to the inner wall of the hemisphere 2, by four bolts25,

extending through said hemisphere and through said plate 24, and having mounted each on its inner end, two nuts 26, the outerof which rests against the plate 24 and the inner of which serves as a lock nut. After the weights l3 and 14 have been adjusted to the positions suitable for counterbalancing the finger holds 4 and 5; the weight 22 may, by being properly turned, be adjusted radially so as to vary the center of gravity of the bowling ball, as desired. By such radial adjustment of the Weight 22 the center of gravity of the ball may be so located as to afford such curvilinear movement of the ball duringthe bowling operation, as the bowler may desire, such curvilinear movement corresponding to the English commonly imparted to a billiard hall.

For convenience in grasping the hemisphere 2 for the purposes of attaching the two

hemispheres

1 and 2 to each other, or for detaching such hemispheres from each other, the hemisphere 2 is provided with two peripheral holes 27 disposed on diametrically opposite sides of the plate 24.

In operating my invention, the

weights

13, 14 and 22 and the finger holds 4 and 5 having been adjusted in positions suiting the 'bowlers convenience, the ball is seized by inserting the thumb and one of the other fingers through the holes 3, the finger holds 4 and 5 being grasped respectively between the thumb and the other finger employed for the purpose. The ball is .then bowled in the ordinary manner. By adjusting the turn-buckle 10 the finger holds 4 and 5 may be positioned as the bowler may desire for his convenience.

Various modifications of my invention maybe made without departing from its spirit.

1. A bowling ball provided with two peripheral holes and two interior finger holds adjacent said holes respectively, one finger hold being adjustable in position relative to the adjacent hole.

2. A bowling ball provided with two peripheral holes and two interior finger holds adjacent said holes respec tively, each finger hold being adjustable in position relative to the adjacent hole.
