UNITED STATES PATENT oFricEj 2,476,678 $313? flifiiiiif Application January 14, 1947, Serial No.

1 Claim. (Cl. 4677) This invention relates balloon type, and

small supply tube extending therefrom through which a lighter-than-air gas may be injected into or extracted from the airplane by a bulb at the end of the tube.

Toy balloons signs and in difierent shapes to imitate or reor gas therein. These toy balloons are sometimes provided with extending cords, but they can only be inflated or deflated by drawing the device downward and opening an inlet nipple thereof.

With these ends in view, this invention contemplates a toy balloon or airplane with a small extending supply tube having a bulb at the end from the toy.

A purpose of this invention is to provide an improved activated toy of the balloon type wherein the toy may be controlled so that it will ascend or descend as the operator thereof desires.

The toy may be of any size or shape, although it is preferred that it be made to imitate an deflated position it may be With these and other objects in view, the invention includes a thin rubber toy or device, such as an airplane, with a small supply tube extending therefrom and with a bulb preferably containing a eras lighter than air attached to the end of the tube.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings. wherein:

Figure 1 is a view illustrating the elements as they appear in use with parts broken away.

Figure 2 is a partial section throu h the body of the device on line 2-2 of Figure 1, with the ends of the wings and lower portion of the supply tube broken away.

The inflatable toy is formed with a body portion, a bulb, and a connection tube, and with a lighter-than-air gas distributed through the parts, the bulb may be compressed to force a be released to withdraw some of the gas wherein the body will overbalance the lifting force and descend.

Referring now to the drawings, wherein like reference characters indicate corresponding parts, the inflatable toy of this invention includes a hollow body III, a supply tube l and a bulb l2.

In the design shown, the body I [I of the toy is provided with wings l3 and M, a rudder 15, an elevator l6 and a propeller ll, The body portion may be provided with a bulge 18 to represent a cabin of an airplane, and the tube II to the under surface thereof connection I9. The opposite end of the tube H is connected to the bulb I2 through a similar socket or connection 2!).

The inflatable rubber balloon or airplane of this invention includes, therefore, a body element which may be made in the form of an airplane, animal or other object or device, a or gas may be injected into the body portion, and a tube connecting said body portion to the bulb.

The elements may be manufactured and supplied in the assembled positions, as illustrated in Figure 1, and the elements may contain a gas that is lighter than air, so that when the bulb is compressed, and air or gas therein forced into the body of the airplane, it will ascend, as

.hereinbefore described.

It will be understood that modifications may be made in the design or arrangement of the lighter-than-air gas, the volume of gas within the balloon when the bulb is released being slight- 1y less than the amount required to cause the balloon to rise, and the increased amount of gas 15 1590973 4 within the balloon caused by the collapsing of the bulb being sufiicient to cause the balloon to rise in the air.
