DIRK GREEUW AND RICHARD R. DE JONG, OF CHICAGO, ILLINOIS.

AIR-SHIP.

SPECIFICATION forming part of Letters Patent No. 758,062, dated April 26, 1904.

Application filed March Z, 1903.

T all whom it may concern,.-

Be it known that we, DIRK GREEUW and RICHARD R. DE JONG, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Air- Ships; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the lfigures of reference marked thereon, which form a part of this specification.

This invention relates to air-ships; and the object thereof is to form an air-ship which can be driven and steered in a desired direction and otherwise controlled during its movement in the air.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation partly in section. Fig. 2 is a horizontal section. Figs. 3 and 4 are vertical cross-sections. Figs. 5 and 6 are details of the gear for operating the rudders.

Referring particularly to the drawings, 6 indicates the balloon or gas-bag. This is long and comparatively narrow and tapers at both ends to a point or vertical edge. It is substantially half-oval in cross-section, the car below forming the rest of the oval. At the front end of the gas-bag is a shield 6", preferably formed of aluminium and adapted to cut the wind during the progress of the car and relieve the gas-bag of most of the pressure. This shield is'outside and in front of the gas-bag, as shown.

The car is indicated at 7 and carries the motive and steering devices. It is formed of suitable frames and covering and is provided with windows, as indicated at 7, and the top frames of the car (indicated at 7 b) form a support for the fabric forming the bottom of the gas-bag. At or about the middle of the ship some of the beams are extended beyond the sides of the car, forming outriggers 7c to support the shafts 8, on which the propellers 9 are mounted. These propellers are shown as six in number, three on a side. The outriggers are stayed by braces 7d. The propeller-shafts Serial No. 145,694. (No model.)

are driven from an engine 10 within the car by chains 10a, which pass through the sides of the car and around sprockets 8 on the shafts. The propellers are located at or hear the median horizontal line of the ship.

The guiding or steering devices comprise front and rear wings 11, a horizontal rudder 12, and a vertical rudder 13. One pair of wings is pivoted to move horizontally at the front of the ship and the other pair near the rear end thereof, as shown. These wings are located just below the bottom ofthe gas-bag and are capable of being drawn in within the sides of the car or projected beyond the same. Under certain conditions of management it is desirable that the wings be out, aswhen the ship is being steered up or down; but in proceeding straight ahead they should be drawn in. The wings are operated by a suitable arrangement of rods (indicated at 11a) connected to the wings and to levers 11b, xed to the roof of the car at a place suitable for convenient operation by the steersman. When the rods are moved lengthwise, the wings are projected or retracted accordingly. The rudder 12 is pivoted to swing vertically and the rudder 13 to swing horizontally, and these rudders are also controlled by rods and levers 14 conveniently positioned within the car.

It is desirable in dirigible balloons of this kind that means be provided to support the same on the ground to prevent it from rolling or falling over when it comes to rest. To this Vend we have provided frames 15, which are side the sides of the car, and thus offer least resistance to the air, and when lowered their curvature causes them to extend below the IOO ythe holes in the car need be no larger than the section of the rod. The rods are drawn in or out and the frames accordingly raised or lowered by suitable levers and connections within the car.

What we claim as new, and desire to secure by Letters Patent, is-

In an air-ship, the combination with a balloon and a car thereunder, of laterally-extending curved frames pivoted to the keel of the car, and swinging laterally and vertically and shaped to lie close to the bottom of the car and to sustain the ship out of contact with the I 5 DIRK GREEUW.
