i Application `filed January 27, 1919. Serial No. 273,388.'

To all whom it may concern:

Be it known that I, GEORGE F. OoHs, a citizen of the United States of America, residing at Newark, in the county of Essex and State of ,New Jersey, have invented new and useful Improvements in Airships, of which j the following is a specification.

The principal purpose of the invention is to provide a new and novel form of airshipI having buoyant element for maintaining 1t aloft, and means for driving it forward7 means for causing itto raise vertically quickly and on an even keel and means for lowering it quickly and likewise on an even keel. To this end the invention comprises a car suspended from a buoyant element designed to receive and hold a light gas or heated air, and longitudinally disposed tubular members positioned two on either side of the buoyant element with one adjacent the bottom thereof, and the other adjacent the top, other tubular members disposed vertically with reference to the buoyant element, and propellers and driving elements therefor mounted in one end of each tube, so that they may eject a stream of air from the remaimng ends of the tubes for the pur-` pose of driving the buoyant element forward, raising it or causing it to descend..`

The driving elements for propellers are controlled from within the car, thereby making it possible for an operator to cause the buoyant element to'ascend, descend or to move forward as is desired.

While illustrated and described in a specificl embodiment the invention is not to be restricted to suc embodiment. Actual certain and the right is claimed to make any which do not deviate from the scope of annexed claims.-

.The same numeralsofreference designate the sameparts throughout the several gv,

ures of the drawing, wherein: v Figure 1. is a view in side elevation. Fig. 2 isa longitudinal sectional view through the structure shown in Fig. 1.

Fig. 3 is a section on the line 3-'3 of ig. 4 is a section on the line 4-4 of Fig'. 1.

, Fig. l5 is a section on the line 5 5 ofl Fig. 1.

Fig. 6 is a horizontal sectional view through the car. j

As shown, the invention comprises a car -A, which is suitably suspended from a buoyant element B in the form of ahollow cylindrical member terminating in conical ends 1. This hollow cylindrical member isdesigned to receive gas or heated air. 0n top of the cylindrical member or buoyant chamber B, there is a pop valve 2, whose purpose is to relieve thepressure interior to f the buoyant chamber when it exceeds a predetermined amount. .,The buoyant chamber Br is made preferably of light sheet metal,

although any other acceptable'material may serve the purpose.

On each side of the cylindrical portion of the chamber B, there is carried a pair of tapering tubular members 3, taperin in the directionof the length of chamber On each side one of these members is adjacent to the top of chamber B, and the other adjacent to the'bottom. The larger ends of the tubular members 3 are at the forward end of the airship and in these larger ends there are mounted the transverse members 4 in which there are journaled shafts 5, which on one end carry propellers 6 and on 'the other ends operatively :connect with driving motors 7, these motors being preferably electrically driven. At intermediate points in, their length, the tubular members 3 are formed with circular side openings 8,

which provides side intakes for fans 9 di.

. protruding from the top of said chambers.

In their lower ends there are carried transversely disposed members 12, each of which support arotatable shaft 13. direct-connected to la driving motor 14 and carrying v at one enda propeller blade 15.

Adjacent to tubular members' 1-1 there are other tubular vmembers 16 also passing throu h .the body portion of the chamber B,

' but a jacent-its sides. These tubular mem- 'd descriptlon.

bers 12 also taper in the direction of their length but are disposed with the small ends projecting from the bottom of chamber B, leaving the larger ends projecting above the top of said chamber. In the top ends of these tubular members 16 there are mounted the transverse members 17, in which shafts 18 are journaled, the latter being connected as shown, to driving motors 19, and carrying propellers 20.

nterior to the car A the means for operating the motors 7, 10, 14 and 19 are carried and these means comprise -an engine 2l preferably of the internal combustion.

type with revolving cylinders such as the Grnome7 which is operably connected to an electric generator 22 by means of a belt 23. Supply means 24 lead from' this generator 22 to the controllers 25, which are three in number, a, b and c and which are connected in parallel With the generator. The motors 7 and 10 are electrically connected with one of the controllers 25 and they may be either serially connected or grouped in parallel with each other. rlhe motors 14 are either serially connected or grouped in parallel with one ofthe other controllers' and the motors 19 similarly interconnected and con' nect'ed with the remaining of the controllersl 25. Thus the operation of either controller .25 will serve to put in motion or to bring to a state of rest any of the motors with which it is connected. These connections between the controllers and the motors are conventional, andtheir illustration is sufficient Interior to the (Qtr Athere is carried a gage 26, which is connected to the chamber B for the purpose of indicating the internal pressure therein.`

At the stern of a. car A there is mounted rudder 28, which is swingably supported on a vertically disposed shaft 29 mounted at the rear of the car. This rudder is formed With a transverse portion 30, to which there connects a cable, the latter-Winding on a drum'32 operable by a pilot wheel 30 for the purpose of operating the rudder one side or the other from a straight course.

The ship is caused to move forward by the operation of the propellers 6 and fans 9, the latter intaking air through the openings 8 and ejecting it in a stream from the smaller ends of the tubular members .3, such streams of air serving to drive the chamber B for- Ward and with it the carA. yAt the same time the operation of propellers 6 serve to draw the ship forward and the blast'from these propellers is ejected through the smalle'r ends of the tubular members 3. cooperating with the blasts/from the fans to assist` further in moving the ship forward. Since the fans 9 and the propellers 6 are underthe control or one of the controllers 25, they will operate only when the controller is in the position permitting them propellers being ejected through the smaller ends of the tubular members 16 to assist in the raising operation.

Likewise, when it isdesired to lower the ship, the -controller controlling the motors 14 is operated to put' the propellers 15 in motion, these propellers then serving to draw the chamber downward and ejecting their blasts through the upper or smaller ends ofthe tub-ular members l1.

In the event that Y it is desired to use heated air in place of a light gas, provision may be made for electrically heating the air by means of electric heaters 37, the latter receiving current from the generator 22 over the wires 34 and 36 and their) attendant controlling means 35, as illustrated inA Fig. 2.

From theforegoing description and the accompanying drawings, it is believed that a clear enough understanding is to be had to render further description unnecessary.

l claimv l. In an airship, a buoyant chamber, a plurality of tubular members mounted on the buoyant chamber, the said tubular mem bers being of tapering shape, a rotatable shaft mounted in each tubular member adjacent its larger end, a propeller carried by each shaft at one end, a driving-motor eX- terior to the tubular member and carried thereby and 'operatively connected to the propeller shaft therein, and a centralized control for said motors whereby the propellers in certain tubular members may be operated for the purpose specied.

2.'In an. airship, a buoyant chamber, a plurality of tapering tubular members mounted on the buoyant chamber and dis-y posed in direction of the length of the latter, a plurality of tapering tubular members also mounted on the buoyant chamber but right-angularly disposed with reference to the longitudinal axis of said buoyant chamber, certain of the right angularly disposed tubular members having their larger ends disposed at the bottom 'of the buoyant chamber, the remainder of said members having theirrv larger ends' disposed/at the top of said chamber, a rotatable shaft mounted in `each tubular member adjacent .the larger end, each` shaft being axillt) a driving-motor supported adjacent each tubular member and in' close proximity to the shaft therein,` positive driving connection between each motor and its attendant 5 propeller shaft, and a centralized control for said motor whereby the propellers in all the tubular members may be put in motion or only those in corresponding tubular members, so that the buoyant chamber may be elevated or lowered or driven forward as 10 herein shown and specified.

ln testimony whereof I aix my signature.

GEORGE F. OCI-IS.
