known as zeppelins or semi-rigid airships.

An important object of the invention is to provide, in a manner as hereinafter set forth a mooring mast of the aforementioned character which embodies means for automatiw cally anchoring the airship as it approaches the mast in order to facilitate securing same to the top of the mast.

ther important objects of the invention isto provide a mooring mast for airships embodying means whereby said airship may be moored thereto in such a manner that the necessity for the services of a great number of people is eliminated.

Further objects of the invention are to provide a mooring mast for airships which will be simple in construction, strong, durable, efficient in its use and which may be constructed at low cost.

All of theforegoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings, wherein like characters of reference designate correspondingparts throughout the several views, and

Serial No. 423,832.

Referring to the drawings in detail, the reference character 1 designates the upstanding mooring mast formed preferably of cementitious material and tapering from its bottom to its top. The mast 1 is mounted centrally on a circular base or foundation 2 having a conical upper surface 3, said foundation being embedded a suitable distance in the ground for the purpose of an choring the same. The lower end portion of the mast l is formed hollow to provide a compartment or operating room 4 to which access may be had through a door 5 as seen in Figure 2.

The mast 1 terminates in a flat upper end and a bore or passage 6 extends centrally therethrough and communicates with the compartment or room 4;. An angular tubular member 7 is mounted for rotation on the upper end of the mast and is provided with a bore which communicates with the bore 6 in said mast, as illustrated to advantage in Figure 3 of the drawings. Cable 8 passes through the bore in the member 7 and extends downwardly through the bore 6 of the mast l and is windable on a Windlass 9 mounted for rotation in the compartment or room t of the mast.

The free end of the cable 8 is provided with a hook 10 the purpose of which will be presently set forth. A vertically disposed Windlass 11 is mounted on the floor of the compartment or room 4 and, as illustrated to advantage in Figure 5 0f the drawings, the Windlass 11 may be operatively connected to an electric motor 12 disposed vertically in a compartment 13 provided in the bottom of the mast. If desired, the Windlass 11 may also be manually rotated in a manner similar to the Windlass 9.

A cable 14: is windable on the Windlass 11 and is adapted to be selectively inserted through any one of the openings 15 extending through the wall of the mast adjacent said Windlass 11. The free end of the cable let is also provided with a hook 16, the purpose of which will be more fully hereinafter set forth.

A series of spaced, radiating substantially V-shaped guide fingers or extensions 17 ex- TOO tends from the periphery of the base or foundation 2, as illustrated to advantage in Figure 1 of the drawings. A series of radially disposed inclined tunnels 18 are provided in the base or foundation 2 and have their outer ends communicatin with the periphery of said foundation or base at a point between he adjacent inner ends of the guide fingers or extensions 17.

As clearly illustrated in Figure 6 of the drawings, the width of each of the tunnels 18 is the same asthe width between the adja cent inner ends of the guide finger 17 and an inwardly swingable door or closure 19 is mounted therein.

The ceiling or upper wall or" each tunnel is provided with a longitudinally extending slot 20 which is open at its outer end. 7

Suitable light 21 may be provided in the upper side of the base or foundation 2 and a light 22 may also be mounted in the angular tubular member '7 on top of the mast for the purpose of guiding airships and facilitating the mooring of sameat night.

In use, as the airship which is designated by the reference numeral 23 nears the mast 1, a cable 24 is lowered therefrom, said cable being payed out from a suitable winding mechanism (not shown) usually carried by the airship. The free end of the cable 24 has secured thereto a comparatively heavy spherical anchor or drag 25 which is secured to said cable 24 through the medium of the stem or rod .26 having the ring 27 on its free end; As the airship approaches the mast, the anchor 25 drags along the ground and enters between adjacent pairs of the guide fingers or extensions 17 being guided thereby intothe tunnel '18, said anchor pushing the inwardly swinging one way door 19 open as it enters the tunnel.

As illustrated to advantage in Figure 7 of the drawings, the stem 26 travels inwardly through the slot 20 in the upperwall or ceiling of the tunnel through which the anchor is travelling. It should be here mentionec that the upper marginal portion of the outer walls of the guide fingers or extensions 17 are provided with the outwardly extending beads or ledges 28, (see Figure 4) "for the purpose of preventing the anchor 25 from being pulled or dragged transversely across one of said guide fingers.

If desired, the beads or ledges 28 may be provided with a metallic protective casing (not shown) to prevent same from being broken off. After the anchor 25 enters one of the panels 18, the

hooks

10 and 16 of the

cables

8 and 14 respectively are connected to the coupling element 29 and the anchor 25 is detached from said coupling element 29. The cable 14 is then payed out from the windlass 11 and simultaneously the cable 8 is wound on the windlass 9. Also simultaneously with this operation the windlass in tion which is best illustrated in Figure 2 of i the drawings, if desired the anchor 25 may now be removed from the tunnel 18 in which it is disposed, as said anchor is of no further use until the airship leaves the mast.

It is believed that the many advantages of a mooring mast constructed in accordance with this invention will be understood, and although the preferred embodiments of the invention are as illustrated and described, it is to be understood that changes in the details of construction may be had which will fall within the scope of the invention as claimed.
