Abstract
Abstract A saucer shaped flying toy has imbedded therein a chirp producing whistle device which operates when the toy is thrown and spun in either direction. The whistle has a raised portion with an elongated sharp-edged opening. The raised portion extends into the airstream passing over the toy to provide turbulent air flow past the whistle opening.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
209 words
A saucer shaped flying toy to be sailed through the air and rotated about an axis of rotation, comprising: a circular central disk having an upper surface; a depending rim positioned concentrically about the central disk and having an outer surface; a curved transition portion positioned between the central disk and the rim, said transition portion having a convex upper surface which provides a smooth transition between the upper surface of the central disk and the outer surface of the rim; a pneumatically-operated bi-directional whistle device projecting about said convex upper surface and having a whistle chamber comprising a substantially cylindrical-shaped hollow body having an axis aligned substantially parallel to said axis of rotation and having an elongated slot orifice located in the side of said hollow body in a plane which is tangent to a cylinder formed around said axis of rotation at the periphery of said toy, said hollow body extending outwardly from the toy into the air, said orifice having a sharp edge bordering the perimeter thereof and being aligned so that, when the toy is rotated in either direction about its axis of rotation, the whistle device is intermittently operated; and protective bumper means located adjacent said elongated slot orifice protecting said orifice from damage.
Claim 2
Dependent Claim
209 words
A saucer shaped flying toy to be sailed through the air and rotated about an axis of rotation, comprising: a circular central disk having an upper surface; a depending rim positioned concentrically about the central disk and having an outer surface; a curved transition portion positioned between the central disk and the rim, said transition portion having a convex upper surface which provides a smooth transition between the upper surface of the central disk and the outer surface of the rim; a pneumatically-operated bi-directional whistle device projecting about said convex upper surface and having a whistle chamber comprising a substantially cylindrical-shaped hollow body having an axis aligned substantially parallel to said axis of rotation and having an elongated slot orifice located in the side of said hollow body in a plane which is tangent to a cylinder formed around said axis of rotation at the periphery of said toy, said hollow body extending outwardly from the toy into the air, said orifice having a sharp edge bordering the perimeter thereof and being aligned so that, when the toy is rotated in either direction about its axis of rotation, the whistle device is intermittently operated; and protective bumper means located adjacent said elongated slot orifice protecting said orifice from damage.
Claim 3
Dependent Claim
18 words
The toy of claim 1 including a plurality of whistle devices symmetrically located about the axis of rotation.
Claim 4
Dependent Claim
20 words
The toy of claim 2 wherein said plurality of whistle devices are positioned symmetrically about the periphery of said toy.
Claim 5
Dependent Claim
22 words
The toy of claim 2 wherein said plurality of whistle devices include at least two whistle devices generating sounds at different frequencies.
