Hemi-BALL.

Specification of Letters Patent.

PatentedApr. 1, 1919.

Application mea December 2, uns; serial No. 134,5'82.

Be it known that I, JACOB ARAHAMsoN, a citizen of the United States of America, and

resident of Asbury Park, in the county of' V known game of hand-ball. The game is aov a favorite form of exercise, and is commonly playedin. gymnasiums. The ball used is of as rubber, though, in some instances, a pneumatic type of ball is employed. As a result of the ball being sphericalin shape, it usually. rebounds with such regularity or precision that skilled players, noting the falling ball, can generally anticipate the direction in which it willlbounc'e or rebound. 'Such being the case, the element of uncertainty or cha-nce is largely eliminated from the game, and this, naturally, detracts greatly n from the interest in the game.,

AAs the particular benefits to be derived from hand-ball are the stimulation of the body through exercise, the development of..

agility, lquickness of the'l eye, and analogous qualities, the object of the present inventmn is to so form a hand ball that its'movements 1n rebounding from a rigid surface will be of an uncertain character; that is to say,

that its angle of rebound will not necessarilyl be substantially the same as the angle at which it strikes the ri 'd surface previous to the rebbund, as is t e' case with a. truly sphericalball. Thus, the primary ob]ect of the invention is to so form ahand ball that a player cannot jud e `with any degree ofl certainty, the direetioii of rebound of the ball, and, therefore,4 this keeps' the-.players on the alert, trains them t0 quicker action,

and makes the game much more difficult to play, as well as' encourages the acquirement of skill, than is the case when ,the game is played in the customary way, with a conventional ball. l

Speaking generally, the invention embodies ,a hand ball, theexterior surface of` which is provided withl a plurality of faces,

1 in contradistiliction to the single face of a spherical ball, so that, when the ball strikes l a rigid surfaceLthe direction of its'bounce will be irregular and uncertain. y Features of the invention, other'than those specified,l will be apparent from the hereinonly, and not as dening the limits of the4 invention. f.

Figure 1 1s a 'perspective view of a hand `4 ball embodying the present invention, and the conventional spherical form, and is generally composed of resilient material, such and, in Fig. 2as having twelve faces. A.

ball made in accordance with the present invention .may embody any number of faces desired, and may, infact, be in the general 'form of a sphere, segments of which are cut away to form substantially flat faces. The salient feature of the invention resides in the fact that the ball is royided with4 a lu-A rality of faces so that, w en it strikes a rlgidsurface, the exact direction of rebound cannotbe anticipated. The players are thus required tobe keyed up at all times during the game, in order to follow the quick movements of the ball as it rebounds in unexpected directions. 4

The ball of this invention is preferably formed from solid ruldber, although, ifrde.

sired, it may be made in the form of a shell, the interior of which is iniiated.

The polyhedron forms of the invention` as illustrated in the drawing, have, in practice, given excellent results. Y By varying the number of the' faces, and incidentally the size and angular relations thereof, the uncertainty of the bound can be determined within-reasonable limits, thereby enabling players, should they so desire, to progres,- sively increase the diiiiculty of the game.- AHaving thus fully described the invention, what I claim as new, and desire to secure by Letters Patent, is: Y

1. A handball provided with a' lurality ofsubstantially plane facesl where y, -when the ball strikes a rigid surface, it rebounds in an uncertain and unexpected direction,
