TOY ROCKET AIRPLANE Filed Feb.l 1l, 1952 g VEN TOR.

Patented July 13, 1954 UNITED STATES orf-FICE 8 Claims.

This invention relates to toy airplanes and moreparticularly to a type of toywhich will simulate a rocket airplane.

Heretofore toys of the nature of this invention have contemplated the use of propulsive means suchl as` air which may be furnished in suitable manner, but generally speaking such toys have not been so arranged as to very closely simulate a toy-rocket airplane, and as a result the value thereof has not been recognized or availed of in most cases.

Usually in toys'of this type the means ofpropulsion may be asr above indicated, air or thel like, or under certain circumstances other types of propulsion may be availed of, in this particular instance the propulsive eiTect of air escaping'from a confined space. is used to accomplish the result and create an attractive device which will be readily salable and result in a large demand therefor.

It is therefore an. object of this invention, to provide a toy rocket airplane which will simulate both in appearance and in actual operation the characteristics of a rocket airplane,l including all of the usual adjuncts generally. thought of as being included in such devices.

It is a further object of this invention to provide a. toy structure which will be simple to manufacture, composed of asmall number of parts the parts thereof being relatively indestructible, and at the same time further enhancing the resemblance of. the toy to what is generally considered to be a rocket' airplane.

It is a further object of this invention to provide a toy rocket airplane which will be made of` tubular telescopic parts, and include within the same the necessary means to effect the propulsion of the device, suitable air supporting. surfaces being providedv in connection with the4 de-V vice, and a simple control being further furnished iti-,order to regulate the speed` of operation of the device. n

Itis a still further objectv ofthis invention to provide a toy rocket airplane of a nature generally referred to above, and in conjunction therewith .to provied a take-off platformwhi'ch willi facilitate the use of the toy and increase itsr action operating characteristics. for the obvi- -ous purposesv of making the samemore attractive and desirable tothe person for Whom the toy is designed.

Other and further objects of this invention will be set forth in the accompanying specioae tion and illustrated in the drawings wherein:

Figure 5 is an enlarged sectional view, somewhat fragmentary illustrating the form of the valve unit which is provided.

Figure 6 is a rear view of the toy.

Figure '7 is a side elevation of the toy when placed upon a take-ofi platform.

Referring now yto Figures l and 2 particularly the toy airplane of this invention is shown as comprising a body or housing, including aforward section generally designated I, and a rear section designated 2. The forward section I includes a tubular member 3 having a closed substantially hemispherical end 4 thereon, said tubular section 3 being adapted to receive therein for movement with respect thereto the tubular portion 5' of the rear section 2. The tubular member 3 inf cludes wing-like members E of any suitable conformation and fixed thereto in any preferred manner, the same being obviously provided for the purposes of Wings to support the device dur-` ing flight. l

The rear tubular member 5 is similarly provided with wing members 'i at opposite sides thereof, said members being fixed in any pre-Y ferred manner to the tubular member fi, and lying substantially in the same planes as the wing members 6 previously referred to.V A suitable stabilizing device as a ruddery or the like, denoted 8, isV provided in accordance with desirable practice, said stabilizer extending upwardly from the top of the tubular member 5 and at substan-V tially right angles to the wing members of the tail section previously mentioned.

Referring now to Figures 1, 3 and 5 particularly, a novel form` of expandible air storage and eX- pellingunit is provided, the same comprising a substantially tubular member 9 composed preferably of a flexible material such as rubber or. the like, saidv member S being provided at its forward end with 'a disc it of similar material, but of substantially greater thickness so as to provide rigidity, saidy Vdisc It acting as a closureV for the forward end of the kmember andfbeing Vsuitn ably sealed thereto so'as to be ain-tight with respect to the member 9. Atransversehole II is formed in the disc iilfor purposes which will be hereinafter explained.'

At the rear'of themember 9- there is'provided a disc I2 of similar dimensions to the discl it previously mentioned, said disc l2l providing a rear closure for the member 9` and being likewise suitably fastened thereto so. as to` be air-tight with respect to the member 9, Substantially centrally of the disc i2,.there is provided an opening I3 adapted to receive therein a valve unitV generally designated, l 4. as shown. inFigure 5.

The valve I4 is made in the form of a rod-like section including threaded portion I 5 on the outer surface thereof, and being of substantial length, the threaded portion being adapted to engage in the hole I3 and in view of the fact that the disc I2 in which the hole I3 is formed, is flexible, the threads I5 will form their own cooperating surfaces within the hole I3. The valve unit, including the rod-like portion I4, is formed at one end with a handle-like section I6 which may be in the form of outwardly extending flat portions as shown in Figure 2. It will therefore be apparent that the valve unit is substantially a thumb screw, the same being further provided with a centrally bored longitudinal passageway I1 therein, extending from the end at which the handle members I6 are provided, substantially to the other end of the said rod-like member I4. As shown in Figure 5, a connecting passage i8 is provided, drilled at an angle to the passage I1 for purposes which will be understood as the description of this invention progresses. It should be noted that the disc I2 is provided below the hole I3 therein, with a transverse opening I9.

With the foregoing in mind and referring again at this point to Figure l, it will be apparent that the flexible and expandible air storage and expelling unit, shown in Figure 3, is adapted to be received within and supported by the front and rear sections I and 2 previously described. Thus, the unit of Figure 3 may be emplaced in the tubular sections of the housing, and is adapted to be fastened thereto at one end by a suitable cross pin 20 entered in oppositely aligned holes in the forward end of the front section I, and adapted to pass through the opening II in the disc II). Similarly, a pin 2I, is adapted to be entered in aligned holes at the rear of the rear tubular housing section 2, and in turn engage the opening I9 in the disc I2. It will thus be clear that the tubular air storage unit is adapted to be maintained within the fuselage of the unit, and will in turn prevent relative rotation of the respective parts thereof so as to maintain the wing sections 6 and 1 in properly aligned relationship. Thus, when the two sections are separated by separation of the respective members thereof as by grasping the front section with one hand and the rear section with the other hand, the air storage unit will be relatively elongated. In view of the fact that the valve member thereof will of course of necessity be in open condition as by the positioning of the valve unit so the passage I8 is connected with the outer air by the passage I'l, subsequent rotation of the valve unit by the handle I E in an outward or leftward direction as viewed in Figure 2, will bring the passage into position so as to be completely shut olf by reason of the fact that the same is within the coni-mes of the disc as respects its opposite surfaces. Therefore the two units will remain in the condition shown in Figure 2, separated, with the air storage unit in its expanded condition and containing air for propulsive purposes as to be now set forth.

If desired, the valve unit may be manipulated by the handle I6 so as to permit air to flow from the storage unit by means of the passages I8 and Il, and move outwardly toward thc rear of the toy, whereby propulsive motion is effected by reason of the escape of air from the air storage unit. It will be apparent that suitable adjustment of the valve unit, so as to permit more or less air to escape through the passage I8, by reason of longitudinal movement of the rod-like 4 member I4, will change the speed at which the unit of the toy moves through the air.

While the toy may very well be launched from a position as held by the person operating the same, under the control of the valve unit as has been heretofore explained, a further desirable manner in which take-off of the unit may be effected is by the provision of a take-off platform designated generally 22. This take-off platform includes a base section 23, and a leg member 24, suitably fastened thereto and at substantially right angles near one end of the base member 23. Thus, the platform will be permitted to assume a tilted position as shown in Figure 7, said flat base member 23 being further provided at its rear portion with an upright ap member 25, suitably fastened to the base member 23. With the toy in position as shown in Figure 7 on the platform 22, it will be apparent that suitable manipulation of the valve unit thereof will permit air to escape from within the air storage and expelling unit, and impinge against the upright member 25 and cause the toy to be propelled from its position on the platform. During the expulsion of the air from within the air storage unit the same will of course contract longitudinally, and thus when the toy has reached the end of its flight movement, by reason of the exhaustion of the air within the air storage unit, said respective members and elements will have assumed the position as shown in Figure l.

There is thus provided by my invention, a novel form of toy rocket airplane which will simulate a rocket airplane of known type or sufficiently so as to attract and hold the interest of youngsters who will use the device, all of the same being simply arranged and including simple parts which may be readily disassembled and assembled or controlled to effect the best possible use of the device. It should be mentioned that the escape of air through the passage Il will of course be accompanied by whistling sounds which will further enhance the realism of the unit and its simulation to a life size unit.
