12 Claims.

This invention relates to toys, particularly to a toy aircraft, and has for its principal object to provide a simple and inexpensive toy simulating an airplane driven by Jet propulsion.

In accomplishing these and other objects of the invention, I have provided improved structure, the preferred form of which is illustrated in the accompanying drawing wherein:

Fig. 1 is a perspective upper side view of a toy.

airplane constructed in accordance with the present invention.

Fig. 2 is a perspective underside view thereof.

Fig. 3 is an end view of the tail assembly.

Fig. 4 is. a perspective view of the rudder.

Fig. 5 is a fragmentary perspective view, partly in section, of the-jet.

Referring more in detail to the drawing:

I designates a toy airplane simulating a Jet propelled airplane in that it is p wered by an escaping Jet of air.

While the air plane is adapted to many variations in construction, I have illustrated a simplifled form which includes a longitudinal member or longron 2 in the form of a stick or rod and which constitutes support for the wings 3 adjacent the front end l thereof and the tail assembly I at the rear end i. The wings 3 may be constructed of any light weight sheet material that is self-supporting such as cardboard or the like cut to shape and adapted to be secured to the member 2; for example, with an adhesive such as used in the assembly of ordinary toy airplanes, or with an elastic band 3' having its ends looped over the rod 2 and extended over the top of the wings as shown in Fig. 2. This method provides for adjustment of the wing along the rod 2 so as to obtain a desired balance.

In the illustrated instance, the wing 2 has a substantially straight forward edge 1 and outwardly and forwardly extending rear edges I. The surface intermediate the front and rear edges may be shaped or left in the flat form as illustrated in the drawing. The Wings 3 are mounted at a point on the member 2 to secure the proper balance and to provide space on the forward end of member 2 to connect flexible, preferably elastic, anchoring strand 9 for an inflatable envelope or bag ll later described. The lateral sustaining members ll of the tail assembly are formed of similar material and have a shape similar to that of the wings and are secured to the end I of the member 2 with an adhesive or the like as in the attachment of the wing structure. The rudder I2 is also formed of sheet material and shaped as best illustrated'in Fig. 4.

In the illustrated instance the rudder has a substantially perpendicular rear edge II, a baseflanges I! and It are spaced vertical slits II and 20. The material between the slots. l9 and 2. is pressed outwardly as at 2| from one side of the rudder and the material between the slits and the front and rear edges II and II is pressed out- .wardly from the opposite side of the rudder as indicated at 22 and to form arcuate loops cooperating to provide a substantially tube-like passage 24 (Fig. 3) through which the nozzle 25 of the bag I! is projected as shown in Figs. 1 and 2. The bag ll may comprise an ordinary toy rubber balloon or envelope and has a knob .28 formed on the end thereof opposite the nozzle or neck 2| whereby the bag is secured to the flexible connection 9 for anchoring that end of the bag so that the bag overlies the upper sides of the wings as shown in Fig. 1. The neck ornozzle 25 projects beyond the rudder and has a rounded annulus 21 to support a tube-like nozzle 30 having an orlflce 3| therein of a size to .allow escape of sufficient quantity of air to effect propulsion of the plane through the air. I

The sound of an airplane may be simulated by equipping the nozzle 30 with'a vibratory reed or tongue II that is supported in the path of the escaping air by a cross member 34.

The device may be provided with retractable landing wheels Ill having supporting arms 38 formed of cardboard or the like and secured to the undersides of the wings by hinge elements l'l formed of relatively stiff fabric so that the hinge elements normally tend'to retain the wheels in perpendicular or landing position relative to the wings. The wheels are retained in retracted position as shown in Fig. 2 by a cord 28 extended over the envelope and having ends extending through openings 39 in the wings and attached to the arms It of the landing wheels 35. Thus, when the envelope is in inflated condition as shown in Figs. 1 and 2, the wheels are retracted, but when the envelope is deflated as shown in the dotted lines 22, the tension in the hinge elements 21 eflects projection of the wheels to landing position.

In using the plane, the bag or envelope is inflated by blowing through the nozzle II, the bag being extended sufliciently so that the elastic tension imparted in the walls is suflicient to expel the contained air at a velocity to provide an escaping jet of suflicient force to cause the plane to soar. As the air escapes through the nozzle, the envelope gradually collapses as indicated by the dotted lines 32 and the plane will glide to the ground. I

I! the nozzle is equipped with a reed 33 as illustrated in Fi 5, escape of the air under pressure simulates the sound of an airplane. Deflationpi' the envelope incidental to escape of the air through the nozzle permits the cord 38 to be drawn through the openings 38 of the wings by the spring action of the hinge elements 31 and the wheels 35 automatically move to landing position by the time the air is expended.

From the foregoing it is obviou that I have provided a toy airplane simulating airplanes of the jet propulsion type and which is particularly interesting and amusing as a toy for children.

What I claim and desire to secure by Letters Patent is:

1. A toy aircraft including a support, sustaining members on the support, an inflatable member'having a discharge nozzle means for anchoring the inflatable member on the support, and means for securing said nozzle in fixed position on the support.

2. A toy aircraft including a support, sustaining members on the support, an inflatable member having a discharge nozzle, flexible means for anchoring the inflatable member, and means for attaching the inlet anddischarge nozzle in'flxed position on the support.
