SPECIFICATION formingpart of Letters Patent No. 742,194, dated October 27, 1903.

To all whom it may concern.-

Be it known that I, GEORGE A. JOHNSON, a citizen of the United Statesfresiding at Parkridge, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Toys, of which the following is a specification.

My invention relates to toys for producing sound, and has for its objectthe production of a soft harmonious sound when rotated. I attain this object by the device illustrated in the accompanying drawings, in which- Figure 1 shows the complete device ready for use. Fig. 2 is "a face view of the casing looking in the direction of the arrow, Fig. 1.

ing a preferably circular periphery and sides convexing outward, so that the casing is thicker at the center than at the periphery. The tubes b 6 extend completely through the casing parallel to the central axis thereof and are located on opposite sides of said axis at equal distances therefrom. Said tubes are designed to receive the cord 0, whereby the device is rotated. 'HBy preference said cordis provided with suitable handles 01 d. Inlet-apertures e e are provided in the obverse side of the casing atsome distance from the peripheral edge thereof, and'on the reverse side of said casing are the outlet-apertures 40 ff, located at or upon said peripheral edge.

The diaphragm g extends across the casing transversely to the central axis'thereof and divides said easing into two compartments. Said diaphragm makesan air-tight joint with said tubes 12 and is otherwise imperforate except for a series of slots h h. Said slots lie radially by preference, and the reeds "it are secured to said diaphragm on the obverse side thereof, as shown in Fig. 8. The arrangement of saidreeds is such'that a current of Application filed November 28, 1902- Serial No. 133,132. (No model.)

air passin'g'through the slots inthe direction of the small arrows,'Fig. 4, will cause said reeds to vibrate and produce a musical sound. The fan or vane j is secured within the easing in such a position as to extend radially and lie approximately in the same plane as the casing-axis. As a result, when said casin g isrotated said vane will tend to throw the air radially outward in conformity to the law of centrifugal action, and consequently will draw air inward through the aperture e and force it through the slots h, past the reeds t, and outward through the peripheral apertures f. This causes the vibration'of said reeds, and a musical tone results.

In operation the device is caused to rotate by first twisting the cord'c, as shown in Fig.

l, and subsequently causing the handles d to Y alternately approach and recede.

Bypreference the reeds i are so constructed reeds mounted on said diaphragm over the 1 slots therein and tubes passing through said casing parallel to the axis thereof said't'ubes making air-tight connection'with said diaphragm and the sides of the casing substantially as described.

2. In a device of the class described, the combination of a revoluble hollow casing, a diaphragm therein dividing the same into two parts, inlet and outlet apertures in said casing on opposite sides .of said diaphragm, a vane in said casing between said diaphragm and the outlet side of said casing, slots in said diaphragm, reeds over said slots, and tubes passing through said casing parallel to the axis thereof, said tubes making air-tight connection with said diaphragm and the sides of the casing substantially as described.
