SELF-PROPELLED AIR-SHIP.

Specification of Letteis Patent. Application filed August is, 1907; Serial No. $88,833,

= Patented Dec. 15, 1908.

To all whom it may concern:

Be it known that I, Gnono Pun, merchant,

subject of the Emperor of Austria-Hungary,

and residing at Vienna, in the Empire of Austria-Hungary, having invented certain new and useful Improvements in Self-Propelled Air-Ships, do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to improvements in air ships of the self propelled type and is pdapted for use either with or without a baloon.

The invention relates more articularly to the propelling mechanism ancf one of its objects is to provide such mechanism which, if used in connection with a balloon, will not only assist in maintaining and reaching the desired altitude but will in addition propel the ship in the desired forward direction.

One of the special features of this invention consists in a propelling mechanism which is adjustable and which if adjusted for the purpose of obtaining a forward movement will serve in such adjustment to also assist in the maintenance of the ship at-the desired altitude.

Another of the principal features consists in the provision of a frame which is adjustably suspended from a balloon whereby the frame may be ad'usted to the desired angle and wherein a bas et or car is supported from said means and is maintained in its normal osition irrespective of the position of the rarne.

Other features of my invention will be more fully set forth in connection with the accompanying drawings and will be more particularly ascertained and pointed out in and by the appended claims. a

In the drawings: Figure 1 is a view in side elevation illustrating an air ship embodying the main features of myinvention. Fig. 2 is a sectional view on line AB of Fig. 1. Fig. 3 is a plan view'of one of the propellers. Fi 4 is a plan view of another propeller.

Iiike characters 'of reference designate similar arts throughout the different figures of the rawings.

\ The invention is illustrated in the specific embodiment shown in connection with a balloon although-it will be understood that a balloon is not essential to a full realization of the advantages of the invention. I

As shown the balloon is designatedat 1 .and'there is suspended therefrom-a support normal position.

which as shown coinprises a yoke 2 connectedwith the balloon oy flexible means in the form of cords or ropesas illustrated.

A frame is indicated at 4 and conveniently said frame is s, own in the form of a ring whicll is movably mounted upon the support 2. Said frame i has a cross section Wl110 as shown comprises a body portion 29 which is bent to form lateral supporting flanges 30. In order to obtain the requisite adjustment ofthe frame 4 with respect to the yoke 2 the latter is provided with rollers 3 adapted to engage said flanges 30 and support the frame by such engagement in a manner clearly shown in Fig. 2. Said flanges. 30 extend throu hout the circumference of the frame 4 and a so serve as a su ort for a car or cage 7. As illustrated in ig. 2 it will be seen that said car or cage is rovided with a yoke 5 having rollers not s own engaging said flanges 30 and servin by such engagement to support said car an permit relative movement of the frame 4 with respect thereto. In order to prevent such relative movement of the frame from displacing the car 7 from its normal or desired position means are provided for connecting said car which means are preferably secured to the yoke 2. As shown said means consists of cables or r0 es 8 connected with theyoke 5 in any desira le manner at one end arid at their other ends with the yoke 2. Conveniently said cables or ropes S are dis osed within the channel or way 31 formed by said bed .flanges 30 al though this disposition of the cables is not essential.

It will be seen from the foregoing that in combination with the balloon and the basket or cage 7 there is provided a frame which is movably interposed between said balloo'n and basket to support the latter from the former and that means are provided for preventin displacement of the basket from its Means are provided for adjusting. the frame 4 relatively to the balloon and basket and as shown said means is disposed in a manner to be accessible to the occupant of the basket. In' the specific embodiment shown a rack 25 is formed on each of the flanges 30 and said rack as shown in Fig. 1 extends throughout a portion of the periphery of said ring 4. Upon' the basket support 5 there is revolubly mounted a shaft 23 carrying gears 22 ada tedto mesh with said racks 25 as clearly s own in Fig. l and on the outer end of said shaft is mounted a crank 24 which serves when turned by the occupant of the car to effect rotation of the ring 4 by reason of itsmovable mountingsor connectlons with the yokes or supports '2 and 5. In order to limit the adjusting movement of the frame 4 means are provided, preferably in the form of stops 26 which are adapted for engagement with the gears 22.

' shown of su e with respect to each other.

In order to facilitate the flight of the ship when the same is beingstarted from a pos1- tion of rest near the ground revoluble supports are provided and as shownsaid supports are in the form of legs 28 which are connected with the frame 4 and are provided with wheels adapted to engage the ground or other-surface supporting the shi prior to flight. These supports maintain t e cars 7 out of engagement with the ground and in cases where the ascent is preceded by a slight lateral movement of the ship these supports revent the car from dragging along the surace and avoid the resultant retarding influence of such action.

A rudder is rovided and as shown is mounted upon t e car 7 and consists of an .extensibleor @bellows-like structure 27. A rudder controlling device is indicated at 32 and is disposed in a manner to be accessible to the occupant of the car.

The propelling means for assisting in obtaining an ascending flight and which also mai'ntains the ship'at the desired altitude and of wheel 1O withthe result that the velocity.

of the air current is increased, thereby correspondingly increasing the ascending impelling action. The result of this construction. 1n practicehas made it ossible to materially reduce the size oft e balloon employed thereby not only reducing first cost but ren- .dering the shi more wieldy and easily managed. In or er to prevent lateral escape of the air from the propeller whee s and to insure an efficient action of the wheel 10 upon the air current generated by wheel 9 means are ,provided in the form of a band 14 which l surrounds the blades of the wheel 9.

Said band insures the formation ofa downwardly directed column or shaft of air toward wheel 10. Desirably wheel 10 is also provided with ,a band which is indicated at 33 and which prevents lateral escape of the air until after Said wheel 10 has acted thereon. Means are also provided for preventing lateral escape of ited volume of air which arrangement makes it possible to obtain a displacement of ai at a much greater velocity than if the air were permitted to escape laterally.

One manner of mounting the wheels 9 and 10 is shown in the-drawings and consists of.

two shafts one of which is convenientlyinithe form of a sleeve. Shaft Ll is mounted at its upper end in a-bearing 34 in the frame 4. At

its lower end said shaft 11 is mounted in a bearing 36. Wheel 9 is mounted on shaft 11 and wheel 10 is mounted on sleeve 12. On the lower end of sleeve 12 is mounted a gear 20 and on the lower end of shaft 11 there is mounted a gear 21. A collar 37 is fi xedto shaft 11 and serves to maintain sleeve 12 at a definite longitudinal position on the shaft 11. Wheels 19 and 39 are provided and are disposed in a manner to cooperate, or if gears are employed, to mesh with'wheels 20 and 21. Preferably gears 20 and 21 are of the same size as are also the gears 19 and 39 whereby rotation of the latter will serve to rotate the former at an e ual speed thereby driving the wheels 9 an 10 at the same speed. It will be seen that the disposition of the gears is such that when ower is appliedto gears 19 and 39 to rotate the same inone direction the wheels 9 and 10 will be rotated in opposite directions. Gears 19 and 39 are mounted upon shafts 17 and said shafts are journaled in bearings 18, as shown in Fig. 7

2, and said bearings are rigidly secured to the frame 4. Each shaft 17 is desirably driven from a prime mover and as shown said rime movers are indicated at 16 and are pen ently supported in driving connection with the shafts 17 so that said prime movers will at all times occu y a vertical position and be maintained in living connection irrespective of the position to which the frame 4 is adjusted as will readily be seen by reference to Figs. 1 and 2.- To this end the bearings 18 are provided with extensions 40 on which are loosely mounted hubs 41 to' which brackets 42 are secured. Said prime movers 16 are mounted on said brackets 42 and are provided with driving wheels 43 which may be connected by belts to wheels 45 on shafts 17.
