A rotary aerial toy comprising a tubular sleeve of flexible material and of circular cross section. In one form of the invention the tubular sleeve tapers from one end toward the other with air entering the larger head end and moving toward the tail end. The head end is adapted for a bridle connection for supporting the sleeve for wind passage therethrough. The sleeve comprises plural strips extending at least generally longitudinally of the sleeve with each strip being of substantially right triangular form, at least at the head end portion thereof. The strips are connected to one another with the hypotenuse leg of one strip being connected to the altitude leg of an adjacent strip and with the base leg being transverse. The strips are arranged at assembly with a step between the head ends of adjacent strips and the seams connecting any selected pair of strips stop short of the head end of the altitude leg of the strip. The head end margins of the strips are secured to a ring to provide airchutes causing the tubular sleeve to rotate. In one form of the invention the strips are spiral along the length of the sleeve, whereas in another form, the strips extend essentially longitudinally of the sleeve. In a further form of the invention, the sleeve can be in the form of a cone. In still another form, the sleeve can be a cylinder. The application also covers the method of producing the above rotary aerial sleeve toys. In a further form, the strips are secured together to form a ringless sleeve. In another form the strips have integral bridle line portions whose free ends are connected by a fastener.

An aerial toy comprising: a sleeve of flexible material, such sleeve being of circular cross section, one end constituting a head end providing an air entry mouth, the other end constituting a tail end, means on said toy for causing a build-up of pressure within said sleeve when it is subject to wind flow, said head end adapted for a bridle connection for supporting said tubular sleeve for wind passage relative thereto, said sleeve comprising plural strips of substantially the same size extending at least generally longitudinally of said sleeve, said strips being arranged annularly in side-by-side relationship, all of said strips being joined together in an annular relationship with each strip being joined with an adjacent strip with the junctures stopping short of the head ends of the strips and with a step being provided at the head end portions of adjacent ones of said strips. The method of producing a rotary aerial toy comprising: providing plural essentially right triangular strips of flexible material, said strips each being of substantially the same size and having a head end and a tail end, seam-securing the strips to one another with the hypotenuse leg of each said strip in contact with the altitude leg of an adjacent one of said strips and with the head ends of the altitude legs terminating substantially the same distance short of the head ends of the hypotenuse legs, and terminating the seam securements short of the head ends of the altitude legs so as to leave mutually adjacent margins of the head ends of said altitude legs free of each other. The method of producing a rotary aerial toy comprising: providing a sheet of flexible material having parallel edges, producing sever lines through said sheet, certain of said sever lines intersecting said edges to divide the sheet into plural mutually discrete sections, other of said sever lines terminating short of at least one of the parallel edges to form integral bridle lines having free ends, said sections having head ends and tail ends, securing the head ends of said sections together to form a mouth for reception of an airstream, said securement being in such a fashion as to leave said bridle lines dangling free except for integral securement at said mouth, otherwise securing said sections together in spaced relation from said mouth to provide structure to cause said aerial toy to rotate when an airstream passes into said mouth, securing the free ends of said bridle lines together to form a bridle.
