To all whom t may cof/wem."

Be it known that L'CLARENCE P. ELLI- THoRrE, a citizen of the United States, and a resident of the city o'f Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Arships, of which the following is a specification.

My invention pertains to an airsliip, and its primary object is' to provide a novel device of this character which is simple and durable in construction, eiicient in use and economical in manufacture. 4Another object. is to equip such a device with casing means which provides one or'more air passages or channels extending longitudinally through i they the airship, and to place a propeller in each of said assages, each propeller being mounted directly o n the shaft of its driving .motor likewise mounted within the passage.

Other objects'will appear hereinafter.

The invention consists inthe combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which, l

Fig, 1 is a vertical sectional viewof my invention;

Fig. 2 is a 0f;

Fig. 3 is an enlarged front elevation thereof Fig. 4 is an enlarged vertical cross section taken on line 4 4 of Fig. 1; and

Fig. 5 is an enlarged horizontal sectional View of the rear portion of my invention.

The particular form of invention illulstrated comprisesa main frame 10, preferably of aluminum with a casing or channel member l1 exten ing longitudinally therethrough and forming a continuous air passage, but two or more such casings 11 ma;Y be used a'nd grouped or placed in any suitable manner within the main frame, and may bev of any approved form i'n cross The main frame includes cross parhorizontal sectional view theresection.

' titions 12 and longitudinalv partitions 13,

s 14 are mounted therebetween.l

and gas ba plurality of separate and thus provi ing a independent 4gas uard member 16 `isl mounted across 4the ront opening of the casing or channel member 11.

' of successive p ulleys 37, 38 and 39,

chambers 15. A meshed I A motor or engine 17 preferably a powerful `gasoline engine, of any .approved con struction, is mounted centrally in the casing, preferably bars 18, and has a propeller 19 mounted on and rotatable with the motor shaft 20 which extends longitudinally of the casing. By thus mounting the propeller directly on the motor shaft, the use and weight of the customary additional supporting frame for the propeller is avoided. 1

The rudder supporting means includes a frame structure 21 mounted to therear of the main frame and containing vhorizontal cross shafts 22 and 23 extending diametrically across the casing 11, andvouter longiby means of frame members or tudinal bars 24 extending forwardly from Y shafts 22 and. 23 to the main frame, as .at25. Horizontal stabilizers or fins 26 are mounted on the frame 21,-forwardly of said cross shaft 22,' and a horizontal rudder 27 is mounted 'on shaft 23 with an upper arm 28 and a lower arm 29 to which cables 30 and 31 are connectedrespectively for swingingsaid rudder on the shaft 23, so as to extend Y 1t at a slant across the rearof the casing or channel member. Said cables 30`and 31 pass over pulleys 32 and 33 mounted on arms 34 and 35 extending from across shaft 22 and from a longitudinal strengthening bar 36 which extends to the rear of rudder 27 and to shaft 23. The cables 30 and 31 continue from pulleys 32 and 33 forwardly over pairs mounted within the casing, and from there pass over additional pulleys 40 on the main frame,as shown, and are attached to a drum or suitable operating element7'41` in the cabin 42 which is mounted beneath the 4airship in any suitable manner. A vertical rudder 44 is mounted on a shaft 45 positioned diametrically at the rear of casing with arms 46 and 47 xfrom which extend cables 48 and 49 passing over successive pairs of pulleys 50,' 51 and 52 mounted in 11 and is provided- -into the cabin to be attached to a drum or suitable operating means 62 in the cabin.

A water container or tank 63 1s mounted in the lower part of the mainframe, and

a gasoline container or tank 64 is preferably mounted on the cabin or beneath the rmain frame, and a conduit 65 extends therefrom to the engine 17. A parachute 6.6 is also provided and preferably mounted as shown.

A dirigible airship embodying my invention is particularly elicient, as the propeller is mounted directl on the motor shaft, to avoid the interme iate gearings and additional mounting means for the propeller, and especially as thepropeller operates 1n the compressed stream of air forced through the casin or tube 11, thus being particularly effective 1n ropelling the airship. The casing or air tu es maybe made round or angular or inany approved shape, and several of the casings or tubes may be used instead of the one tube as shown; and furthermore this form of construction is not only useful for passenger carrying airships, but will also find application and be roduced in the-form of toy ballons or airships, and lind application in various similar ways.

While I have illustrated and described the preferred form of construction for carrying my invention into effect. this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the recise details of construction set forth, but esire to avail myself of such variations and modifications as come within the scope of the appended claims. Y

Having described my invention, what I claim as new and desire to secure by Letters Patent is: y f

1. An airship having a casing extending longitudinally therethrough, a ropeller with a motor therethrough mounted in said casing, a plurality of separate gas compartments arranged around said casing, and a water container in the lower ones of said compartments. y Y

2. An airship having a casing extending lon 'tudinally therethrough, a propeller wit a driving motor mountedin said casing, gas compartments arranged around said casing, a cabin beneath said compartments, anda shaft of pliable materialrwith a ladder extending from said cabin through one compartment into said casing' adJacent said motor. l

3. An airship having a casing extending preferably con- 1,581 sse y longitudinally therethrough, a frame including a pivot shaft mounted horizontallyjto the rear of said casing, a horizontal rudder mounted forwardly on said Ishaft to extend diametrically` of said casing, cable guiding rear portion of said airship, a pivot shaft mounted rearward of said stabilizers, a horizontal rudder mounted to swing on said shaft and extending therethrough forwardly toward said stabilizers, and cable means extending to rudder.

5.,An airship having a casing extending longitudinally therethrough, a snp orting frame includinga vertical shaft at t e rear of said casing, a vertical rudder mounted on said shaft, a horizontal shaft mounted rearward of said vertical shaft, a horizontal rudder mounted forwardly of and to swing on said horizontal shaft, and means for extending said rudders. atV a slant across the rear of said casing.

6. An airship havingI a casing extending longitudinally therethrough, a propeller within said casing, a mo rear of said casing, a horizontal shaft on n0 said supporting frame, a horizontal rudder extending forwardl from said shaft, arms extending from sai rudder, arms extending from said supporting frame and having nlleys thereon, and cable means exten in from the first arms over said pulleys throng said casing for swin g said rudder to extend at a slant to tldlrear of said casing. 8. An airship having a casing providing a longitudinal air horizontal and vertical stabilizers at the rear of said airship, a horizontal bar mounted rearward of said casing, a horizontal rudder mounted forwardly onv said bar to swing vertically therewith, a vertical rudder 125 mounted forwardly of the horizontal rudder, and cable means 9. An airship having av casing extending' longitudinally therethrough to provide an air passage,

said cabin for swinging said 35 torj in said casing for driving said propeller, a ,cabin mounted 190 cabin passage therethrough, '12

for swinging'said rudders.

gas compartments arranged 13 around said casng, a motor mounted centrally in said casing, a propeller on the shaft of said motor, a horizontal rudder mounted to the rear of said casing to extend diametrically -ofr said air passage, means for.' swinging said rudder at a slant across said air passage, a vertical rudder mounted to the rear of said casing, and means for swinging said -vertical rudder at a slant across said air passage.

In testimony whereof, I have signed my name to this specification.
