Application October 6, 1950, Serial No. 188,812

v 8 Claims. 1

This invention relates to toys and more particularly, to aerial spinning or flying toys.

It is a general object of the present invention to provide a novel and improved flying rotor type of toy adapted to simulate a flying disc or flying saucer.

In particular it isan object of the invention to provide. in a flying saucer type of toy, a rotor adapted to be spun on and launched from a rotation imparting device, adapted to be held by the operator, and includin substantially radially disposed, pitched blades attached to a peripheral shroud ring which depends therefrom and is shaped to improve the hovering characteri'stics of the rotor.

Another object of the invention consists in the provision of a rotor of the type described wherein the shroud ring or skirt is concave toward, and in a radial plane containing the axis of rotation and has an inner diameter at the top less than that at the bottom to cause the trapping of the vortex air column delivered. by the vanes to slow the sinking of the rotor as the speed of rotation decreases.

Qne of the. important features of the invention resides in the use of a skirt or shroud. ring of considerable depth formed from an opaque materi'al and provided. with a number of relatively large perforations through which. light passes during the rotation to improve the appearance of the device and produce the sensation of fire jets as supposedly used to propel the controversial "flying. saucers.

Another important feature: resides in the provision of numerous large perforations in. the shroud ring of a rotor of a flying saucer type of toy together with the use of transparent or translucent closure means tor these openings to achieve the air confining efiects of the shroud while permitting the passage of light and effecting tart-colored displays during rotation.

Other and further objects and features oi the invention will be more apparent to thosev skilled in the art upon consideration of the accompanyi'ng drawing and following specification wherein is disclosed a single exemplary embodiment of the main portion of the invention with the understanding that such changes and modifications may be made therein as fall the scope of the appended claims without departing from the spirit of the invention- In said drawings? 1 is a top plan view of a flying saucer toy constructed in accordance one embodiment of the invention;

Fig. 2 is a side elevation thereof;

Fig. 3 is abottom plan view of the rotor unit;

Fig. 4 is a radial section taken through the rim of the rotor unit as on line 4-4 of Fig. 2;

Fig. 5 is a section through one of the blades taken on line 5-43 of Fig. 1;

Fig. 6 is a fragmentary plan view of a modified rotor hub as mounted on a different type of launching device; and

Fig. 7 is a side elevation of the upper portion of the launching device of Fig. 6.

Heretofore numerous flying toy devices have been proposed and used, each comprising in gen eral a vaned or bladed rotor formed of thin metal, cardboard, plastic or the like and adapted to be given a spinning motion about a substantially vertical axis by, one form or another of launching devices held in the hand of the operator. This rotary motion was imparted-by a pull string, a, wound helical. spring or even the spin:- ning action or a small stick rotated between the palms of the hands as one is slid over the other. These devices in general have sufier'ed from one or more defects which are now more apparent as the devices are used in congested areas. If imparteda sufficiently high speed of rotation to remain in operation for a satisfactory time the rotors travel rapidly and to a considerable height and because their flight is erratic and uncontrolled they are often lost. They were restricted to outdoor use because of the height of flight and in some cases the unprotected ends of the rapidly rotating blades injured youthful users.

In accordance with the present invention, a

'rotor is provided which is arranged to produce is achieved with but minor changes and without any additional or supplemental parts.

Referring now to the drawing and first to Figs.

lto a inclusive, the device will be seen to comprise two separable parts, a soaring rotor Ill and asti'ck It adapted to be held in the operators hand. The rotor includes a spool-like device 1 2, centrally bored at 3 for a loose fit over the end 'o-fthestick. A string wrapped around: the spool, before the device is placed on the stick, and afterwards rapidly withdrawn imparts the spinning action necessary to cause the rotor to take 011. in flight. The type of mechanism used to achieve the rotation and consequent launching forms no important part of the present invention. The improvements reside wholly in the form and construction of the rotor or flying saucer.

The novel features of the invention reside in the construction of the rotor which is preferably formed from some light metal such as sheet aluminum or from a suitable moulded plastic. The rotor takes the form of a unitary wheel having a central hub disc I5 which may be attached in any suitable manner to the spool mum at the outer end. The exact shape transverselyand the amount of average pitch will assist in controlling the type of flight.

The tips of the blades are connected together by a shroud ring [8 depending as a skirt from the blade tips as clearly seen in Fig. l, and having a convex outer surface to heighten the saucer or disc appearance. The thin shroud ring is concave facing the axis of rotation in a radial plane in which this axis lies as clearly seen in Fig. 4. Here and in Fig. 2 it will be noted that the shroud has a generally squat, barrel shape but the portion adjacent the upper edge I9 is given an'increased curvature and the diameter at this edge is the minimum. The maximum diameter occurs near mid-height and the diameter of the lower edge 20 is intermediate that at' I9 and at mid-height.

' This arrangement enhances the confining efiect on the vortical air column which is forced down- -wardly by the rotation of the blades and guides it in a relatively straight'path preventing erratic lateral flight and insuring lift almost directly in the line of the axis at the time of launching. By giving the blades their maximum pitch at the center, this effect is increased and leakage below the edge of the shroud minimized. The overhang at the top edge of the shroud contributes materially to the effect and the overall result is that the rotor is caused to hover rather than climb rapidly or to rise or descend more slowly and over a much longer period of time than with the unshrouded rotor or'with shrouds of difierent shapes.

The above results have been proven' in tests by perforating the shroud with a large number of large openings such as shown at 22 in the .drawings. With these openings unobstructed the operation is much like that of an unshrouded rotor but when they are covered by strips of cellophane or the like as shown at 23 and 24 in Figs. 2 and 4, then the hovering characteristic .ismaterially improved and even after the rota I tional speed begins to drop off materially there is no rapid descent.

The holes 22 are not primarily for the purpose of permitting changes in the operational characteristics, although they can be used for that purpose. They achieve a lightening of the rim or shroud and where the latter is made of opaque material permit the passage of light rays giving a novel effect as the rotor spins in the .air and particularly against a bright sky. Such ace 1 unit is rotated.

effect is considerably augmented if the openings are closed by transparent, translucent or colored material such as the previously mentioned bands of adhesive cellophane. More simply the rim can be dipped in a self-hardening colored plastic which forms a film over the openings. The openings may be individually covered by different colored fillers and as shown, they may be of various shapes and sizes to achieve the desired decorative and luminous effects.

In Figs. 6 and '7, is shown a modified launching device including a handle 25 having a spool 26 fixed thereto and rotatable thereon. This spool is provided with a pair of upwardly projecting driving lugs 21 having their forward and rear faces inclined in the direction of rotation. These lugs are adapted to pass through properly shaped slots 30 in the hub disc. Dining the spinning operation, which is achieved by drawing a wound string oil the spool, the inclined forward faces 3| of the lugs hold the hub down against the flat top of the spool. but as the spool tends to slow down after the string is drawn off it the increased relative speed of the rotor causes the rear edges of the openings in the hub to climb up the rear inclined surfaces 32 of the lugs and separate the rotor from the launching device.

One important feature of a curved shroud not mentioned heretofore is the considerable added stiffness which it imparts to the whole rotor because of its curvature in two directions. The rotor can thus be made extremely light and quite rugged. It is also strengthened by dishing, i. e., having the hub portion somewhat elevated above the rim of the shroud as shown.

The device as described is a safe, easily used toy, satisfactory for use indoors or out and one that will give unusual" pleasure to children of all ages.
