Application filed December 1, 1909. Serial No. 530,882.

To all whom it may concern:

Be it known that I, ALBERT O. PAULSON, a citizen of the United States, residing at i Los Angeles, in the county of Los Angeles,

both lateral and fore and aft stability in an airship, and as it is well known in the art that the box kite possesses the most stable form for horizontal translation, I have adopted together with ceratain improved features which at once renders it more available for vertical translation.

One of the great dihiculties inherent in the box kite formation is the inability to change the direction or the angle of flight, and to this end I have provided a simple and eflicient means whereby the structure may be directed through the air at any desired inclination from the horizontal, or it may be easily turned in either direction while in flight, without requiring any appendages, such as movable horizontal planes or rudders, as will now be set forth in detail.

In the drawings, Figure 1 is a side elevation of my improved airship. Fig. 2 is a top or plan view. Fig. 3 is a view of the front end of the airship. Fig. 4 is a perspective view of one of the box kite elements. Fig. 5 is a side view showing detail of mechanism for changing the angle of the Q propeller shaft; and Fig. 6 is an end view showing details of the mechanism for changing the angles of the shaft.

In constructing my invention I provide a frame, which in this instance comprises two horizontal parallel bars 5, a suitable distance apart, joined at their ends, and having, preferably, at the forward end two wheels 6, and a single wheel 7 at the rear end. The engine is mounted on this frame a little to the rear of the middle portion, and a shaft 9 extends forwardly through a vertically-movable bearing 10, terminating at a propeller 11, which is mounted thereon. The shaft has a universal joint 9 near the engine, so the forward end of the shaft may be raised or lowered, a pair of hinged links 8 having their lower ends journaled to the axle shaft, and their upper ends to the bearing 10, and the bearing 10 is adapted to move vertically in a guide 10 An operating bar 11 attached to the hinged connections of these links, extend back to the operator and has a handle 12 by means of which the shaft 9 may be raised or lowered.

The supporting surfaces are two box kites, mounted diamond-shaped and so mounted on the frame as to have an edge at the top and bottom. The forward kite 12 has its lower sides, or the corner thereof, cut away a width equal to the distance between the frame members 5, and approximately midway between its ends are downwardlyprojecting ears 13 which are secured to the frame members by pivot pins, so the upper end of the box kite will swing fore and aft a limited distance.

The rear box kite ll is similarly cut away at its lower corner or edge, and has at its upper corner or edge an arm 15 which has a socket to receive therein a vertical post or rod 16. The lower end of this rod rests in a gudgeon 17 on the frame, and an eye on the frame, (not shown), holds the lower end of the box kite in alinement. This construction permits the rear end of the box kite to swing laterally. In order to hold the rear box kite in position the frame members are provided with two cross pieces 18 19, which project beyond the frame a suitable distance, and posts 20 21 extend upwardly from the ends of these cross pieces converging at an eye 22 through which the vertical rod 16 passes. Suitable stay wires 23 21 extend from the end of these cross pieces to the frame fore and aft.

Toggle jointed levers 25 26, secured to the eye 22, on the rear kite, at 27, hold the front kite in position. An operating arm 28, hinged to a toggle jointed connection, extends down to the region of the operator, and the inclination or angle of the front box kite can thereby be regulated at will.

The rear box kite may be swung in either direction by means of cables 29, which are attached to the outer corners of the kite, and these cables extend down to the ends of the cross pieces 19 and thence to any point (not herein shown) within reach of the operator.

The box kites are similarly constructed, as each has a lateral rigid wing at the outer corners, and within is a pair of transversely-disposed supporting surfaces 81 in the form of blades, narrow fore and aft, as shown. It will thus be seen that while the two kites are normally in alinement with each other, they may be adjusted independently of each other, the forward one to give the angle of flight, and the rear one to direct it laterally.

In order to provide a more efficient means to utilize the supporting surfaces while in vertical translation, the open or cutaway portion in the bottom of the kites aflords means of admitting air, and by adding the 7 surfaces 30 31 a much larger efficient surface is obtained for practical work than would be possible if the kites were closed up as usually constructed. The structure can in this manner be made exceedingly light and compact, assuring the utmost stability fore and aft and laterally, while utilizing every available surfacefor sustaining purposes while in flight.

The angled disposition of the sides of the kite members from the vertical are at such in clinations as to afford the utmost stability, since they serve as dihedral angles more efficiently than if the sides thereof were vertical.

When the angle of the forward box kite is changed, or when it is desired to launch the ship, the relative angle of the propeller shaft may be changed by means of the operating bar 11 which is moved back or forth at the will of the operator.

What I claim as new, is:
