FLYING OR AIR CAR.

Specification of Letters Patent.

Patented Jan. 7, 1908.

Application filed May 16.1906. Serial No. 317.232.

particularly to that type in which the flotation is assured by means of propellers and in which the gas bag commonly employed is eliminated.

The invention aims to provide a dirigible car provided with steering means of'novel construction and of novel operation, which in the performance of their functions co-act with the propelling means.

The invention particularly comprises a car of the type set forth provided with a series of propellers which exert a lifting influence by generating a downward current of air. This current is utilized in directingthe car, and for which purpose a series of adjustable inclined blades or vanes are provided which interce t the downward current of air at an ang e, in order to give the car a lateral displacement in the desired direction with relation-to its vertical position as controlled by the lifting means.

Means are further-provided for directing the downward current of air upon the inclined blades or vanes, and this means comprises a canopy, which in addition to the function above noted, serves the dual function of a covering or awning to protect the occupants of the car from the elements, and of an expansible parachute to compensate for momentum in the downward movement of the car.

In connection with the several novel means above described, the invention has for a subsidiary object the provision of a light framework and of a cover therefor which shall offer the least resistance in the lifting and flight of the car, in order that the car may not be impeded in its elevation and travel by the weight and form of it's component parts.

The detailed construction will appear in 1 the course of the following description, in

which reference is had to the accompanying drawings forming a part of'this specification, likenumerals designatin like parts throughout the several views, w erein Figure 1 is an elevation of car constructed in accordance with my invention, Fig. 2 is a 'similar view showing the operation of the canopy in its expansible action to serve as a parachute, Fig. 3 is .a top plan view, the canopy being removed, Fig. 4 is a detail longitudinal section of the canopy and the supporting collar therefor, Fig. 5 is a detail side elevation of an adjustable steering blade or vane, Fig. 6 is a side elevation of a car similar to that shown in Fig. 1, but ofsomewhat different shape and embodying a slightly modified adaptation of parts, Fig. 7 is a vertical transverse section of the same, and Fig. 8 is an elevation of an eflicient mechanism for adjusting or setting the steering blades or vanes.

In the referred embodiment of my invention, I employ a light framework 1, formed of tubular metal and comprising supporting corner posts 2 which converge upwardly toward a common meeting point and give the frame 1 the conformation of a pyra mid. Secured to the posts 2 at a short dis tance above their lower ends, is' a rectangular frame 3 which forms a support for the superstructure of the car and upon which the floor of the car is secured. A railing o1 guard entirely surrounds the car and" comprises vertical corner posts 4, secured to the osts 2 and frame 3, and top, side bars an end bars 5. Depending from the frame 3 is a substantially inverted cone or cu -shaped basket 6, within which is mounted t e motor 7 and the transmission gear 8. The gear 8 is of the differential type and serves to simultaneously drive in opposite directions'a hollow shaft 9 and a shaft 10 extending therethrough in interior concentric relation. The shaft 9 carries a propeller l1 and the shaft 10 carries a propeller 12 in superposed relation to the propeller 1 1 and having its blades disposed at an angle thereto.

The propellersll and 12 are arranged in accordance with well known laws of physics,

anism is impelled in a direction 0 posite to the direction of travel of the o ect ropelled. The posts 2 have connection at t eir upper converging ends with an annulus 13, from which a canopy 14 is loosely suspended in any desired manner. A practical embodiment of this feature is shown in Fig. 4, wherein the canopy 14 carries at its upper edge a series of suspension hooks 15 engaging loosely in apertures 16 provided therefor in the annulus 13. I

The canopy 14 is constituted of a plurality whereby the current developed by the mech-' their lower ends with cushioning elements for absorbing the shock when the car makes a landing. The cushioning elements comprise springs 19 carried by adjustable collars 20, sleeved upon the posts 2 and blocks or shoes 21 carried by said springs 19. Mounted upon the side of the car in bearings provided in the frame 1, are horizontal stub shafts 22,

carrying at their inner ends hand wheels 23 and upon their outer ends, rigidly secured steering blades or vanes 24 for controlling the l direction of travel of the car. The blades 24 are adjusted at anyudesired incline by rotation of the hand wheels 23 in the roper direction and are disposed so as to receive the downward currents of air generated by the propellers 11 and 12 in their lifting action. These currents are deflected outward at an angle u on the blades or vanes 24 by the inclined sides of the canopy 14.

' For the purposes of testing the working of the apparatus, or resisting a too rapid descent when the motor has been cut off too soon, I provide manually operated means for actuating or blocking the propellers 11 and 12 comprising crank shafts 25 carried in the framel and provided with sprockets over whichare trained chains 26 operatively connected to the gearing 8. When'the crank shafts are operated by hand, movement'is imparted to the gearing 8 and the propellers 11 and 12 are driven in the desired direction.

The construction shown in Figs. 1, 2 and 3 comprises a car formed with equilateral sides and a substantially circular canopy. The construction shown in Figs. 6 and 7 coinprises a car of elongated proportions provided with an oval canopy 18. In the construction shown in Figs. 6 and 7 a modified adaptation of propellers is employed, comprising propellers 27 arranged at each end of the car and the propeller 28 disposed therebetween in superposed relation and overlying the horizontal plane of the propellers 27. The propellers 27 and 28 are severally driven from vertical shafts 29 extending through the car and operatively connected to the gearing 8. The steering blades or vanes 24 are arranged preferably in airs on each side of the car and singly at eac 1 end of the car.

With reference to Fig. 8, a novel adjusting means of steering blades or vanes 24 is illustrated, comprising a hand crank 30 provided with a beveled pinion 31 meshing with a similar pinion 32 carried upon a drive shaft 33 provided with a differential transmission 34 suitably supported at the end thereof and through which motion in the desired direction is imparted to the blade or vane 24 connected thereto.

In operation the propellers 11 and 12 have a lifting action and raise the car in a sub stantially vertical line of travel by generating a downwardly traveling current'of air; which being deflected outward upon the 1nclined side of the canopy 14, and impinging upon the blades 24 which there present themselves at'such angles thereto that the downward currents of air upon the same will so 0 crate as to effect a lateral or angular disp acement of the car as desired, by which means the car is balanced, steadied and steered.
