DIBIGIIBLE AEROPLANE.

Application filed March 26, 1926. Serial No. 97,492.

This invention relates generally to aeroplanes, the invention having more particular reference to a novel type of dirigible aeroplane.

The invention has for an object the provision of a dirigible aeroplane, which will prevent accidents due to stalled motors and the like while flying, as the helium used in connection with my improved device Wlll 36 enable my improved dirigible aeroplane to float in the air.

Another ob'ect of the invention is the provision of a irigible aeroplane having increased flying area, as the helium used in 35 connection with my improved device will enable the motor to be stopped, when prevailing winds are favorable.

A further object of the invention is the provision of a dirigible aeroplane having a means of gassing or exhausting the helium used in connection with my improved device, as may be required to raise or lower the dirigible aeroplane, when the ordinary means for this purpose is disabled, so as to allow continued use of my dirigible aeroplane, and

prevent accidents.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims inwhich the various novel features of the invention are more particularly set forth.

Fig. 1 of the drawings, is a front elevational view of my improved dirigible aeroplane.

Fig. 2 of the drawings, is a top plan View thereof.

Fi 3 of the drawings, is an enlarged perspectlve view of the wing, thereof, showing the helium tanks.

Fig. 4 of the drawings, is a side elevational view, showing amodification of my improved dirigible aeroplane.

Fig. 5 of the drawings, is a top plan view thereof.

Fig. 6 of. the drawings, is an enlarged perspective view of the wing thereof, showing the helium tanks.

5 Referring in particular to Figs. 1 and 2 of the accompanying drawings, the underbody 10, the wheels 11, the wings 12, propeller 13. the motor 14, and the adjustable wing members 15, are of common ordinary construction such as generally embodied in aeroplanes of this type.

The tanks 16, may be of any suitable size 7 and shape, preferably such as will fill the space, adjacent to and between the-upper longitudinal struts 17 and the lower longitudinal struts 18, the forward vertical braces 19 and the rear vertical braces 20, of the wings 12. The helium tanks 16 are rovided with suitable connections 21, exten ing preferably downward therefrom, and having valves 22 with convenient hand wheels 23, or any similar suitable handles for closing and opening the said valves 22, so as to allow helium to be taken into, or exhausted from the said tanks 16.

It being understood that I do not necessarily limit the above mentioned construction to the aeroplane as above described.

Referring in particular to Figs. 4 and 5, of the accompanying drawing, in which I have illustrated a modification of my improved dirigible aeroplane, the motors 24, the propellers 25, the forward wings 26, the rear wings 27, and the heretobefore mentioned component parts, as here shown and designated by similar reference numerals,

are of common ordinary construction such as generally embodied in aeroplanes of'this type.

The tanks 28, may be of any suitable size and shape, preferably such as will fill the space, adjacent to and between the upper longitudinal struts 29, the lower longitudinal struts 30, and the forward vertical braces 31, and the rear vertical braces 32, of the forward wings 26. The tanks 33, may be of any suitable size and shape, preferably such as will fill the space adjacent to and between the upper longitudinal struts 34, the lower longitudinal struts 35, and the forward vertical braces 36, and the rear vertical braces 37 of the rear wings 27.

The tanks 28 and 33, are provided with connections 38, having suitable valves 39 with pinions 40 operatively attached thereto, and meshing with suitable gears 41, rigidly attached to the shafts 42, which are rotatively mounted in suitable bearings car-- ried in the supports 43, rigidly attached to the hereinbefore mentioned win as at 44. The shaft 42 has rigidly attac ed thereto bevel pinions 45, meshing with the bevel gears 46, rigidly attached to the second shafts 47, rotatively mounted in suitable bearings-48, attached to any convenient part of heretofore mentioned dirigible aeroplane, so that the hand wheels 49, rigidly attached to the second shafts 47, are within reach of the operator of my improved device, so as to permit the operator to open the valves 38, and release or exhaust any part or all of the helium contained therein.

It will be further understood that the above mentioned construction is a preferred embodiment of my invention. It is to be understood that I do not limit myself to the precise construction herein disclosed, and the right is reserved to all changes and modifications comlng within the scope of the invention as defined in the appended claims.

. Having thus described my invention, what I claim as new and desire to protect by Letfers Patent of the United States is as folows:

1. In a device of the class described, a dirigible aeroplane comprising front and rear wings, struts comprising spaced members supporting said wing, means for retaining as 'of a weight lighter than air mounted etween the spaced members of the struts of saidv front and rear wings, valve mechanism for controlling the gas content of said retaining means while said aeroplane is in operation to selectively vary the lifting power of the front and rearwings of said aeroplane for effecting changes in the direction .of movement thereof.

2. In a device of the class described, a dirigible aeroplane comprising front wing, meansfor retaining gas of a weight lighter than air mounted on the front wings of said aeroplane, valve mechanism for controlling the gas content of said-retaining means for varying the lifting power of said front wings while said aeroplane is in operation, rear wings, means for retaining gas of a weight lighter than air mounted on said rear wings, valve mechanism for varying the content of gas in said rear wings, and operating mechanism for said valve mechanism conveniently located in the pilot house'of said aeroplane for selectively varying the gas content of said front and rear retaining means for changing the elevation of the front of said aeroplane relative to the rear thereof.

In testimony whereof I have afiixed my signature.

JULIUS FOX.
