Specification of Letters Patent. Patnted June 21, 1921,

Application ledctober 9, 1920. Serial No. 415,730.

To all @elw/m i may concern.'

Be 1t known that I, FERDINAND H.

ScHULTz, a citizen ofthe United States, and

a resident of Treynor, in the county of Pottawattamie and State of Iowa, have invented a 'certain new and useful AFlying Toy, of which the following is a specilication.

The object of my'invention is to provide a flying toy of extremely simple and inexpensive construction.

More particularly it is my object to provide a flying toy adapted to be projected a whirling movement,

will fly substantially on a level for aconsiderable distance and will then rise higher Vin the air before starting on its downward course. Y

Wththese and other objects in view, my invention consists in the construction', arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in thev accompanying drawings, in which:

Figure 1 shows a planview of a flying toy, embodying my invention.

Fig. 2 shows aninverted-plan view ofthe same.V Fig. 3 shows a front elevation of the device shown in Figs. '1 and 2.

Fig. 4 shows an end elevation.

Fig. -5 shows a detail, sectional view taken on the linee-5 of Fig. 2. y v l Fig. 6fis an enlarged end elevation, the dotted lines being diagrammatic illustrations of the positions taken by the wings in flying; and

Fig; 7 shows a diagrammatic view of a portion of the flight of the toy'.

My improved flying toy is made of a substantially rectangular strip of somewhat resilient material, preferably spring brass or the like.

The strip is represented generally by the reference character A and has its blades indicated by the reference numerals 10 and 11 at its ends. and a central portion 12, as

illustrated. I

The forward edge of each blade from the vcentral portion to the end ofthe blade is bent upwardly from the central-portion 12, as illustrated at 1 3. ,The immediate for@ ward edge of each blade issharpened somewhat, as at 14. l

The side vedges of the have flanges 15 folded central portion 12 over on the upper side of the strip. as shown for instance in j A i Fig. said folded over portions extending beyond the central portion for a portion of the length of the rear edge of the blade. The rear edge of the vblade is normally straight and parallel with lthe folded over portion 15, as illustrated at 16 in Fig. 3.

By bending the'forward part of the blade upwardly, as at 13, the forward edge isv stiffened, so that it will not bend as easily as the rear edge of the blade.

The central portion 12 is provided with a central opening or hole 16.

The flying toy is given a rapid whirling movement by means of a gun or the like 17, shown in Fig. V7, whereupon it will vfly into l the air and will follow asubstantially horizontal path after leaving the gun for a short distance, and will thereafter, toward the end of its flightv curve upwardly in the air for a considerable distance before starting down. f

The toy will fly a considerable distance, and if given rapid rotation will fly from eighty to' two hundred yards, while the length of the flying toy isprefe'rably only from five to six inches. l

I have shown in Figs. 1' and 2 an actual size in which the toy may be made. I

The peculiar path followed by the toy is taken for the followingreasons:

During the first part of the flyingmovel ment and while the rotation of the toy is very rapid, the raised portions of the front edges of the blades, which are on opposite sides of the blade,'tend to give the toy a climbing movement or to cause it to climb in the air. The force of gravity, of course, tends to pull the toy down, and the resistance of the air against the under side of the back of the blade tends to spring the back of the blade upwardly on acccount of its resiliency and construction, and on account also` of the slight twisting movement given to the blades through the center of the device. 1

The back edges of the blade tend to spring upwardly into or toward the plane of the forward edges, as illustrated by dotted lines in Fig. f5, or the lines B illustrate the posi1 i tionk assumed by the rear edge and end part downward. flight.V

` during the very vsothat during said rotation both edges of the outer ends of the blade will stand slightly Y of the blade shown at C.

When the speed of rotation becomes reduced, the resiliencyy of the back ofthe blades is suiicient to overcome the air pressure, and the back edges of the blades assume their normal position, whereupon the steeper pitch of the blades will cause a sharper climbing movement of the toy causing the toy during. the latter part of its flight to climb higher into the air from the horizontal path, which it has heretofore taken.

A large number of experiments with the ltoy herein described show that it will fly along for a substantial distance and will then fly upwardly before descending on its By using the vfolded over reinforcing strips 115 and having them project part. of the distance along the back edgeof the blade, it will be seen that it is the back-outer poi'- tion of theblade, which is sprung upwardly rapid rotation' of the toy,

above the plane of the central part 12.

. 'On its downward finishing flight, the toy will swing around` in a curve back toward the starting point.

' uWhile some changes may be made in the construction and arrangement of my flying toy, I believe the construction and shape of the blades should be substantially that shown herein, and described, but it is my intention to cover'by my claims, any slight v portion,

reinforcing ortion being arranged to overlap apart o one edge of the other blade.

2. A flying toy comprising a strip somewhat resilient material, having a central portion and oppositely extending blades, the inner edge of each Vblade being stiffened for a portion of its length adjacent to the central portion ofthe toy. Y v

3. A flying toy comprising aV strip of somewhat resilient material, having a flat central portionl and having blade portions projecting in opposite directions therefrom, the opposite forward edges'of said blade portions vbeing curved upwardly from the central por tion, so that the forward edges of the blades are raised with relation to the central portion and the back edges of theblades, 4and are curvedv near the central portion and are substantially straight near their outerends, said central portionrhaving reinforced'parts flatV at its side edges overlapping portions of the back edges of the blades, said blade portions heilig capable of being sprung from their normal positions during the flight ofthe toy.

a. A flying toy comprising a stripof some what resilient material, having a flat central Y portion and having blade portionsprojecting in opposite directions therefrom, the opposite forward edges of said blade portions being curved upwardly from theV central so that the forward edges ofthe blades are raised with relation to the centralportion, and the forward edges ofthe blades are curved near the central portion and are substantially straight near their outer ends, the rear edges of said blades being ar-V ranged substantially in straight' lines 'andin the same plane as that of the c'entralportion, said central portion having at its side edges reinforcing parts overlapping the portions of the back edges of the blades, said blade portions being capable of beingsprung from their normal positions duringthe flight of thetoy.
