Application iiled December 29, 1926. Serial No. 157,830, and in Norway April 23, 1926.

This invention relates to an airshlp without any gas filling or bearin plane and wherein the raising is effected y means of motor power. The invention is characterized substantially in the arrangement of a sufficient numberof vertical screws which are placed in tubes passing through the hull vertically and further a sufficient number of horizontal screws also arranged in tubes passing through the hull lengthwise.

1n the drawings an example of carrying out the invention is shown.

Figure 1 is a side view in longitudinal section on the line I-I of Figure 2.

Figure 2 is a cross section on the line SHLII on Figure 1.

' Figure 3 is a detail view of the ship seen from the rear and showing a perforated tube for watering purposes.' Figure 4 is a detail view of the ship seen from the rear showing the use of skids.

The airship consists of a cigar-shaped hull 1, which inits lon itudinal centre plane is provided with pre erably 6 vertical screws 2, 3, 4, 5, 6 and 7 placed in fixed tubes 9, 10, 11, 12, 13 and 14 extending through the entire hull. Said tubes are at the lower part preferably a little widened to make the entrance 'of the air easier. Thescrews are extended over the hull to enable them to better catch the air. The shafts 16 of the screws are supported at'their upper ends in a longitudinal beam-17 xed to the hull and at their lower ends in transversals 18. Each shaft is provided with a worm 19 meshing with a wormwheel 20 mounted on a long shaft 21 arranged lengthwise in the hull. This shaft is provided with a sprocket wheel 23 with chain 24 leading to a sprocket wheel 25 mounted on the motorshaft 26. The motor 27 is fixed on'the door 28 which is arranged at a suitable height from the shipls bottom 29 in such, a manner that under t e oor a compartment 30 is left, which for example can be filled with water, when the ship 1s to be used for watering purposes or the like and in this case there may be arranged outside the hull a perforated tube 33 which is connected to the water compart-A 50 ment. In the lower part of this comparoment there may be a ed se arate cont tainers 34 and 35 for water b ast, when the ship is used on-sea. At the lower ps .rt

of the ship there are arranged lengthwise preferably two screws 40 and 41 for the longltudinal propulsion of the ship. These screws are arranged in tubes 42 and 43 stretching through the entire hull and are at the rear at the air discharge end somewhat flattened to provide a flat stream of air 1n order to act more efficiently upon the rudder 44, which is laced between the tubes. The rudder may 'e connected with a suitable steering apparatus, which is placed in a steerlng house 45 on the top of the ship. The shafts 46 and 47 of the screws are provided with sprocket wheels 48 and 49 with chain 50 in such a way that the screws are moved simultaneously. The shaft 46 is provided with a sprocket wheel 51 with chain 52 running to a wheel 54 mounted on the shaft 55 of the motor 56.

In front the ship is provided with a turn- Iable ring having four openings two of which 61 (one shown in the drawing) register with openings 62 for the inlet to the tubes 42 and 43 for .the horizontal screws 40 and 41. The two other openings 72 are arranged at the lower part ofthe ring and are destined to register with the openings 63 for vertical tubes 64, which are leading down to the horizontal screws` and are to be used when the ship is going on sea, as the usual inlet openings for the horizontal screws must then be closed to prevent the entrance of the waves. Such closing is obtained by means of ring 60, which to this end is turned about 180 so that the openings 61 are moved away from the openings 62 of the tubes 42 and 43 at the same time as the lower open ings 72 will register with the openings 63 for the vertical tubes64 inorder to enable access of air to the screws 40 and 41.

The ship is provided with wheels 66 in order to enable it to be moved on the shore. Further the ship may be provided with wide skids 67 for use on snow, and in this case there may be arranged driving-screws of a. larger diameter than it would be necessary for air-traic.

The vertical screws can be made with a diameter of 1.20 m. and the horizontal screws,` with a diameter of for instance 0.75 m.

The arrangement of the screwsin tri passing throu h the entire hull has the advantage that e air current from the screws will not act dep upon the hull, but

will pass withoutany hindrance through the ship. Thereby the shi is always maintained in a correct uprig t position.

I claim:

1. An airship heavier than air, comprising a hull, horizontal and. vertical channels through the same, air screws in said channels for supporting and moving the airship, said horizontal channels being flattened at .their rear end, and a side rudder between the rear ends of said horizontal channels.

.2.v An airship heavier than air, comprising a hull, horizontal and vertical channels through the'same, air screws in said channels for supporting and moving the airship,

said hull at the front being provided with ing a hull, horlzontal and vertical channels throu h the same, air screws in said chan-` nels Ior supporting and moving the airship, said vertical screws being extended over the hull to enable them to better catch the air', above said screws a longitudinal beam ixed to the hull forming a support' for the upper ends of the shafts of said screws, transversals in the vertical channels forming supports for the lower ends of said shafts.

4. An airship heavier than air comprising a hull, horizontal and vertical channels lthrough the same, air screws in said channels for supporting and moving the airship, said vertical screws being extended over the hull to enable them to `better catch the air, above said screws a longitudinal beam fixed to the hull forminga support for the upper ends of the shafts of said screws, transversa-ls in the vertical channels forming supports for the lower ends of said shafts, each of said shafts being provided with a worm meshing with a wormwheel mounted on a lon shaft arranged lengthwise in the hull, sai long shaft being provided with a` chain leading to afsprocket wheel mounted on the motorshaft, said motor mounted on the door.

5. An airship heavier than air comprising a hull, horizontal and vertica channels through the same, air screws in said channelsV for supporting and moving the airship, said horizontal channels being flattened at their rear end, and a side rudder between the rear ends of said horizontal channel said rudder being connected with a suitable steering apparatus placedin a steering house on the tcpnof the ship.

v 6. airship eavier than air, comprising a hull,l horizontal and vertical channels through the same, air screws in said channels for supporting and moving the airship, said vertical screwsbeing extended over the hull to enable them to better catch the air, means arranged above said screws and fixed to the hull forming a su port for the upper ends of the shafts of sai screws, and means in the vertical channels forming supports for the lower ends of said shafts. l

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