' Application filed February 29,1924. Serial No. 695,955.

To all whom it may concern:

Be it known that I, KARL ARNsTnIN, subject of the Czechoslovac Republic and residing at Friedrichshafen-Bodensee, Germany, have invented certain new and useful Improvements in Air-ships, of which the following is a specification.

The invention relates to an airship, the bow of which is built up in such a manner that it may be anchored at its point.

It is evident, that by this mode of anchoring at the point of the airship, considerable forces are exerted between the body of the airship and the anchoring device, and therefore the bow of the ship is placed under great strain.

It was therefore necessary to deviate from the streamline form of the ship, which was the most favorable from the aerodynamic point of View, especially with regard to in clined positions of the airship, and to construct the bow of the same in such a manner, that it was formed in the shape of a pointed body, which was joined tangentially to the primary form of the hull proper.

According to the present invention, this form which impaired the efliciency, is avoided and the manner of transmitting the forces from the airship body to the anchoring point is improved in statical relation by joining to the front part of the ships hull a conical or pyramidal frame-work, which is arranged, for its greater part, within a stream-line casing adapted to give the most favourable form to the ship.

That part of the conical or pyramidal frame-work projecting from the casing may suitably be made so small, that the generating line of this cone forms with the generating line of the surface of the ship an angle, which is essentially smaller than 180, and this angle may preferably be rounded.

By constructing the frame-work which transmits the forces from the airship to the anchoring point in the form of a pyramid or cone, the forces are transmitted directly by straight lines to one of the ring girders forming part of the main body of the hull, so that it is possible to reduce the weight of the construction to a minimum.

This construction has the further advantage that the ship, by having a projection extending from the hull, may be moved within a'greater cone 'around the anchoring point, without having thebody of the hull 5 come into contact with the anchoring device (the platform of an anchoringmast).

In the accompanying drawings, Fig. '1 shows in elevation the arrangement of the bow as formerly made. shows a bow arrangement in accordance with the present invention.

Fig. 3 shows the new bow in side-elevation on a larger scale, and

Fig 2 similarly w Fig. 4 shows the new device embodied in an airship of the rigid type, together with its anchoring device.

In Fig. 1 the form hitherto known is represented. In the place of a bow following the stream-line b, a pointed conical projection 0 is built out on the primary body of the ship.

In Fig. 2 a conical or pyramidal structure d is joined to the primary body a of the ship, which is enclosed for its greatest part in a casing e of the most favorable or stream-line form. The angle, formed by the generating line of the cone with the gencrating line of the ship-body is characterso izedby the letter a.

It is suggested that the ship be so designed that this angle is considerably smaller than 180", for the smaller this angle is made, the more nearly the ship approaches the desired shape. 'The point of the cone d and the angle formed between the cone and the hull body may be rounded, as shown in Fig. 3.

In Fig. 4 an airship of the rigid type is shown, which is provided with the new arrangement. For the purpose of a better representation the outer envelop is removed. The airship consists as usual of longitudinal girders f and cross ring girders 9.

To one of the last ring girders g the coni- Having thus described the construction of my invention, what I claim as new and desire to secure by Letters Patent is:

1. An airship comprising a substantially streamline shaped how, an anchoring point outside of said bow and structural means connecting said anchoring point with the rear portion of said bow, said bow enclosing the main portions of said connecting means.

2. An airship comprising an anchoring point formed at the extreme bow of the ship, members connecting said anchoring point to a portion of the ship situated considerably to the rear of said anchoring point, said members in their main portions being situated inside of the outer shape of the airship.

3. An airship comprising a hull, an

anchoring point at the forward end of said hull, structural members connecting. said anchoring pointto a' portion of the ship situated considerably to the rear of said anchoring point, and a shape giving forward portion of said hull, said forward portion enclosing said connecting structural members.

at. In an airship, a frame work comprising longitudinal girders and ring girders, a bow following a substantially stream-line form an anchorin oint formed at the eX- treme bow of the ship and straight girders connecting such anchoring point with a ring girder. I

In testimony whereof I affix my signature.

KARL ARNSTEIN.
