JULIUS STEIN, OF BOSTON, MASSACHUSETTS.-

-MUSlC-BALL.

SPECIFICATION forming part of Letters Patent No. 620,087, dated February 21, 1899.

Application filed September 28,1898- Serial No. 692,076. (No model.)

To (ti/Z whom it may concern:

Be it known that I, JULIUS STEIN, a citizen of the United States, residing at Boston, in

the county of Suffolk and State of Massachuforming a hollow air-reservoir which is airtight, excepting as hereinafter specified, and a sound or music producing device which is located within the cavity of the ball, is held at its outer end by said envelop, has an entrance or mouth in line with or substantially in line with the outer surface thereof and at the outer end of a passage connecting the interior of the ball with the outer air and through which the air of the interior of the ball is adapted to be forced and through which also air isdrawn into the cavity of the ball, and which passage has at its inner end, or adjacent thereto, a music-producing reed or device.

In the drawings, Figure l is aview in plan of the music-ball. Fig. 2 is a view in vertical section taken through the center of the music or sound producing device.

Referring to the drawings, A represents the elastic ball, and B the sound or music producing device, extending from the outer surface a of the ball into the cavity or air-chamber a thereof, and which has the passage 1) connecting the air-chamber a with the outer air, and which has across its inner end a sound or music producing reed or device 12'.

this air through the device, either by hand or otherwise, the sound or music device is operated.

The sound or music device is represented The ball is made of air-tight flexible material of as provided by means of a wooden cylinder 12 the end b of which extends through the envelop of the ball and is securely united to the ball by rubber cement and in a manner to prevent leakage at the joint. The inner end which is contained in the ball, is concave and has a sharp edge b surrounding the entrance to the passage 1) and across which a narrow strip 1) of thin rubber, forming the reed, is stretched, the rubber being secured in its'stretched state to the end of the cylinder by a winding b of thread or string extending about the ends of the rubber and about a reduced portion of the cylinder adjacent to the end.

The wooden cylinder or sleeve extends very nearly across the cavity of the ball. The outer end is small and is contained within the spherical surface of the ball and does not modify or change the shapeof the ball. The reed b is at the inner end of the sleeve and so throttles the passage as to prevent the air with which the ball is filled from leaving it or being forced from it when the device is used as a ball, and thus prevents the application of the musical device to the ball from injuring its elfectiveness as a ball, while, on the other hand, it may also at any time be used as a sound or music producing device without adding anything thereto or removing anything therefrom by collapsing the ball toward the side of the sleeve or cylinder, but not toward its inner end. By collapsing it toward the side the ball is elongated and the air forced into the inner end and through the passage of the sleeve. By collapsing the ball in the other direction the envelop is forced against the inner end of the sleeve and oreases it.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States As an improved article of manufacture, a

toy music-ball having a spherical air-tight collapsible rubber case orenvelop and an inwardly-projecting sound or music producing device comprising a sleeve contained in the cavity of the case, the outer end of which is small and which is attached to the envelop to be within the outer surface thereof, and -it is forced therefrom by pressure applied to which sleeve extends very nearly across the the ball upon each side of the sleeve.

cavity of the ball and has a passage extend- T ing from its inner end to the outer air, which JULIUg STEM passage is throttled bye narrow strip of thin \Vitnesses; rubber stretched across its opening, and F. F. RAYMOND, 2d, whereby air is kept in the ball except when J M. DOLAN.
