HENRY TREBE, or iNDIANAPoLIs-"INDIANA, AssIGNoR To HIM-` SELE'AND FREDERICK KLARE 1 Letters .Patent No. 93,249, dated August 3, 1869.

TOY-BALL.

The Schedule referred to :in these Letters ?atent and making part of the same.

tion of a return-balk7 of unich less diameter than those in use heretofore, and'of a spherical, or concavoconvex receiving cup for the same, and lof sti-inging both-the cup and ball to one end of asmall India-rubber string, while a small ring is placed at the other end of said string, by which it is to be held between the thumb and finger when in use.

When the string is thus held, and the cup Iand ball thrown o, the contraction of the string afterwards brings them back to the hand, the ball settling within the concavity of the cup just before reaching the hand, with a smart explosive or aspirato noise.

Considerable skill may be acquired in the use of this toy, so as to vary the musical noise thus made, by varying the vibrations of the string from a short to a long stroke, and vice versa.;

This toy, therefore, furnishes all the amusement that can be in any return-hall, while in addition it possesses an element for the play of juvenile ingenuity, in' the production of very plain musical sounds.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I desire that the drawings herewith sent, shall constitute a part of this specific description, by reminding the reader that like letters on the various figures always refer to like parts. v Figure l is a side elevation ofthe spherical cup A, barely showing a small segment of ball B, as the hall rests within said cup whenl the string-is relaxed.

Figure 2 is the same as fig. 1, with the exception oi having enough of the cup A out away to show the ball B, as it rests within A, when quiescent.

Figure 3 is a view of the cup and ball when in use, by the alternate expansion und contraction of the rubber string S.

These cups and lballs may be made of any kind of light resonant wood, or other vibrating material.

The cup A may be made of any sizeA to suit thc faucy,about tw'o inches being the maximum size in its outside diameter. It must be made perfectly round or spherical, after which aconcave recess is bored or turned out, vto a sufcient depth to almost hide the solid ball B, when the latter is drawn in by the contraction of the rubber string S.

This coneavity is shown in iig. 2, with its long axis parallel tothe grain of the wood. The short diame ter of this recess is just a shade more than the diameter of ball B, and about two-thirds that of A.

The hall B is turned solid, and in size so that it will just enter the cup-like cavity in A, without any yfriction against its sides.

YVhe'n the cup and ball are thus prepared, a small hole is puncturedthrough each one, for'the string S, exactly in the centre of each. The string vis lirst drawn through B, and then down through the bottom, of A, and securely held by a small pin of wood thrust in the holes by the side of S.

A small'1netalring,-or anything equivalent, may be tied to the upper end OLS, as shown in iig. 3.

Now, upon taking hold of S, as represented,

iingers, in fig. 3, the cup and ball are v'thrown offrom the hand, as shown in this same figure. When the'cup and yball are at the greatest distance from the hand, they are each the greatest distance from each other, as seen by the stretching of the rubber cord intervenlng. Y

As they are both returning to the hand, the cup 'gradually gets nearer the ball, its speed being acceleratedby the contracting cord between them, until the cup reaches the ball just below the liand, as shown by the dotted gures in fig. 3, and the ball passes within A just as they reach the hand.

As B is entering the mouth of the cup A, it always touches the edge of the cup enough to cause a vibration and musical sound, paltly from the elasticity of the wood, and partly from a sudden displacement' of the air contained within the cavity it is entering.

Having thus described my invention, and the mode of operation,

What I claim as new, and desre'to secure by Letters Patent, is

The combina-tion of a retun1-ball, B,with spherical concavo-convex cup A, when the two are strung upon the end of an elast-ic string, S, as shown and dcscribed, and for the purposes set forth.
