This invention relates to improvements in a toyaeroplane of the whip 'type which may be manipulated manually.

Toy aeroplanes which may be controlled in `flight from the end of a string or other support" have been previously developed to provide a toy which may be whirled around from the end of 'l the supporting means so as somewhat to resemble 'a full sized aeroplane in ight. Such toy planes as previously developed, however, have had only la limited scope of manipulation such, for example, as merely whirling the plane around in a circle about the head of the operator.

It isan object of the present invention to provide a toy including a miniature type aeroplane which is connected to a suitable manipulating support, said support being capable of whip-like movements whereby the toy aeroplane may be g moved so as to simulate themovement of a full sized aeroplane by executing take-offs, landings,

rolls, figure eights, turns, banks, and other maneuvers.

It is another object of the invention to support a toy aeroplane upon means which are flexible ture is extremely simple, capable of inexpensive .manufactura rugged and durable in use, and

pleasing in appearance. Details of these objects and ofthe invention, as well as other objects thereof are set forth in `the following specification and illustratedin the accompanying drawing comprising a part thereof.

Referring to the drawings: Figure l is a view of a person operating a whiplike toy plane embodying the principles of the present invention, said figure illustrating in dotted lines an exemplary path of movement of said toy plane. n

Fig. 2 is a plan view of the whip-type toy plane illustrated in Fig. 1 but shown on a larger scale v than in the latter ligure.

Fig. 3 is a side elevation, partly in section, taken on the line 3-3 of Fig. 2.

Fig. 4 is a fragmentary sectional View taken on the line 4 4 of Fig. 2.

The whiptype toy aeroplane embodying the principles of the present invention comprises a miniature aeroplane I0 formed from a flat sheet I2 of thin, relatively stiff material shaped to provide a wing I4 and a stabilizer or tail I6 extending rearwardly therefrom. For convenience and simplicity in manufacture, the wing and tail may be formed integrally as illustrated in the figures, but such formation is not to be considered restrictive. The material used to form the sheet I2 may be heavy paper of tagboard weight, parchment, synthetic resin of any suitable stiffness,l or light weight metal. Flap portions I 8 of the sheet I2 initially projecting forwardly from the leading edge 29 of wing I4 are folded backwardpreferably against the under surface of the wing I4 and secured to said wing by any suitable means such as a plurality of wire staples 22. Such folded flaps providelongitudinal bearing cavities 24 which are in axial alignment with each other. The bearing cavities `24 preferably enclose an .elongated tubular bearingsleeve 26 whichin the preferred embodiment of the invention, is continuousv from one tip end of the wing I4 vto the other as clearly shown in Fig. 2. Such bearingsleeve 26 may comprise, for example, a ,soda straw of suitable length.

lSecured to the sheet I2 and extending along Athe longitudinal axis thereof is a fuselage comprising astick 28 of any suitable light weight `material such as light weight wood. The sheet I2 may be secured to thestick 28 by any convenient means, such as a plurality ofwire staples 30 whichV` are forced throughfthe sheet and into the wood.. The stick 23 projects at its forward end beyond the leadingedge 20 of the wing I4 and, in the preferred embodiment of the invention, the forward endof the stick terminates in an enlargedhead 32 formed from material similar to the stick 28.`-

Asimple propeller 34 formed from sheetsynthetic resin, laquered paper, or otherwise is centrally apertured to receive a headed pin 35 which extends through the propeller and is driven into thehead 32 in such manner that the propeller is freely rotatable relative to thehead 32 as the plane I0 isl moved forwardly through the air. Thestick 28 affords rigidity to the aeroplane I0 Alongitudinally thereof and said stick preferably .terminates at its rearward end adjacent the rear edge of the tail of sheet I2. The forward edges ofthe tail I 6 may also be provided withflaps 38 which are folded against either the top or bottom surface of the tail I6 and are secured thereto bywire staples 40. Such folded flaps strengthen the leading edge of the laterally extending tail surfaces and also stiifen the tail.

The aeroplane I is supported by one end portion of a control member comprising a resilient rod orflexible Wire 42 which is preferably piano wire. Piano wire is relatively high quality steel wire having a carbon content of from .75 to .85%. Such wire is flexible but is appreciably more rigid than many forms of soft iron wire, for example. The use of piano wire is desirable to permit the user of the plane to achieve the desired manipulations of the aeroplane IIJ when pivotally supported at one end of thewire 42 as will be described hereinafter. Said one .end portion of thewire 42 extends entirely through thebearing sleeve 26, said one end of the wire terminating slightly beyond one tip of the wing I4 and a Washer 44 is secured to said end ofwire 42 by peening or riveting, so as to prevent the washer from being removed from said end of the wire. Said washer preferably abuts either the .adjacent tip end of kthe wing E4 or the end of thebearing sleeve 26 adjacent the same, or both. The other end of thewire 42 extends a substantial distance laterally from the other tip of the Wing I4.

Secured to the extreme end portion of said other end of thewire 42 is a ball or aknob 46 which is manually held in the hand of theoperator 48 during use as illustrated in Fig. l. TheWire 42 extends through thebearing sleeve 26 in a direction perpendicularly to the longitudinal axis of the aeroplane I0 and said bearingsleeve 26 is positioned relative to the aeroplane I!) at substantially the center of gravity thereof, or possibly very slightly forward of said center of gravity. It will also be noted from Fig. 4 that the preferablycontinuous bearing sleeve 26 is disposed between thestick 28 and the adjacent surface of the wing i4. In order to provide a space for thebearing sleeve 26 as described, the wing I4 is curved in a direction transversely to the length of the wing and suchcurved portion 50 provides a partial channel which serves to strengthen the wing longitudinally of the length thereof and transversely to the longitudinal axis of the entire aeroplane. The tubular configuration of thebearing sleeve 26 also further strengthens the wing against bending from the general plane thereof and the disposition of one end of the relativelystiff piano wire 42 Vwithin thebearing sleeve 26 also adds very materially to the strength of the wing to prevent bending thereof from its normal plane.

From the foregoing it will be seen that the disposition of thewire 42 within thebearing sleeve 26 at the leading edge of the wing pivotally connects the wire and aeroplane for free rotation of the aeroplane about the axis of the wire.

When theknob 46 on one end of the Wire '42 is held within the hand of theoperator 48, the wire may be manipulated in whip-like fashion while the Wire is rotated around by the operator either in front of him or over his head or otherwise in such `manner that kthe aeroplane may be made to loop, roll, bank, take off and land from the ground or any other surface, execute gure eights and numerous Yother types of manipulations so as gracefully to `simulate "many of the various possible maneuvers of an actual aeroplane in flight. kSuch manipulation Vof the aeroplane upon the end of thewire 42 also causes thepropeller 34 to be rotated and produce a Whirring noise, thus adding to the .simulatio of a full sized aeroplane.

It has been found that the relation of the Weight of the aeroplane i0 to the length and diameter of thepiano wire 42 is of importance for purposes of producing the desired manipulations of the aeroplane IU most advantageously. For example, it has been found that a toy aeroplane having a wing spread nearly 1/3 of the length of thewire 42 and weighing approximately 2% oz. may be most advantageously manipulated as desired upon a piano wire having diameter and a length of approximately three feet. Such length of said diameter of piano wire may be bent 'in a loop until the ends meet without permanently 'distorting or bending said wire. The general proportions discussed above are similar to those illustrated in the dra-wings and particularly Fig. l. ll\Totwithstanding the aforementioned proportions and ratiosfhowever, it is to be understood that the other details,l of the present invention may be utilized advantageously in toy whip-type aeroplanes having proportions that vary some what 'from those stated above.

It will be seen from theforegoing that the present invention provides a whip-type toy aeroplane which may be inexpensively constructed so as to be light in weight, rugged and durable and capable of relatively long life. The toy aeroplane being supported from one end of a flexible but relatively stiff length of piano wire is 'capable of being manipulated and cause the aeroplane to simulate gracefully numerous maneuvers of an actual aeroplane and with a -minimum of effort and movement by the hand of the operator by which the aeroplane and supporting wire are manually manipulated. The toy may also manually be manipulated for extensive periods of time Iwithout tiring.

While the invention has `been illustrated and described in its preferred embodiment and has included certain details, it should be `understood that the invention is not to be limited to the precise details herein illustrated and described since the same may be carried out in other ways, falling within the scope of the invention as claimed.
