Abstract
Abstract A device adapted to be thrown through the air and to spin about an axis through the device as it sails through the air. The device has a number of whistles on the outer periphery thereof for emitting a sound as it spins due to the air passing through the whistles because of the spinning action thereof. The whistles are symmetrically disposed on the device to provide dynamic balance therefor.

Claim 1
Independent Claim
199 words
An amusement device to be sailed through the air with a spinning motion comprising: a hollow, circular, dome-shaped body provided with an open bottom, a central axis, and an outer periphery, said body adapted to be thrown with a spinning action through the air so that the body spins about said central axis and sails through the air; a number ofo elongated whistles mounted on said body at said outer periphery at symmetrically and circumferentially spaced locations thereon, each whistle having an air passage extending at least partially through the body and circumferentially of said outer periphery, and a vent extending inwardly from said outer periphery to said passage and communicating therewith, there being an inclined vane adjacent to each vent and extending into the corresponding passage, each whistle having an air inlet opening at least partially facing the direction of spin of the body, and an air scoop surrounding each air inlet opening, respectively, and projecting outwardly therefrom, whereby air will enter each air inlet opening as the body spins about said central axis and sails through the air to thereby cause a sound to be emitted by each whistle as a function of the spinning action thereof.
