Within the tube 22 50 s1ons, one of wh1ch, for the-purpose of illusthere is provided a hollow tubular standard perspective of 27 having a flange 28 at the top thereof (Fig. 5) which fits into the interior of the member 19 and rests upon gaskets 29 interposed between the flanges 24 and 28. The said standard 27 is referably of a larger diameter at the top tlian at the bottom thereof.

Secured to the standard 27 as at 32 there is a short perforated cylindrical member 33 to which there is suitably secured flanged plates 34 forming a recessed disk-like stabilizer or auxiliary anchor. A main anchor 35 similar in shape to the anchor 33 but prefer; ably provided at the center thereof with a universal joint 36 to which there is secured one end of a cable 37 securely held at its opposite end by means of a clamping collar 38 resting on top of a cover 39 on the tube 19. To erect my apparatus I tow the cylinder 10 which at this time (that is before erection) is provided in the chamber 20 with a pair of winches 45 upon which the cable 37 1s wound. These winches are geared to-' gether by gears 46 and'47 and geared to a driving motor "48. It will be understood that the anchors 33 and 35 are close up to the cylinder 10 during the towing thereof since the cable is still woundv on the winches 45. When the location for the apparatus has been decided upon, the valve 13 is opened which causes water to flow into the chamber 12 and act as a ballast to right the cylinder. When the cylinder has assumed an upright position the motor is started and the cable commences to unwind, carrying the anchors 33 and 35 downwardly. When the flange 28 of the standard 27 comes in contact with the flange 24 or with the gaskets 29, it will stop its downward movement, but the cable and anchor 35 will continue downwardly until the said anchor strikes bottom.

At thistime a stop 50 is slightly secured to the cable and is let down through. the tube V 19 until it abuts the flange 28 of the standard 27 when all further downward movement of the cable and anchor will cease. The stop consists of two sections 51 having clamping flanges 52 at their sides provided with openings to admit clamping bolts-53 to pass therethrough and these sections are also provided at the bottom with tapering diskportions 54. When in the position above referred to, screws in the hub 17 are tightened against the tapering surfaces of the disk ortions 54 which bear against the flange 28 o the standard with a, gasket 55 interpassed between them to make a substantially watertight joint. After this is accomplished the cable is severed near the top of the tube 19 the cover 39 is placed upon the tube, a loop 57 is formed on the cable and the collar 39 is secured at the bottom thereof. The winches 45 may now be removed from the cylinder.

Durin the lowering of the anchors salt water Wlll have entered into the tube 19 through the tube 22' since the standard is of a lesser diameter at the bottom than the inside diameter of the tube 22. To drain the salt water from the tube 19 I provide a drain cock 58 as near the bottom thereof as practicable. The reason for making the standard of different diameters is that the cable is heavier at the top thereof than at the bottom and a substantially good fit is desirable between the walls of the standard and the cable.

After the cylinder 10 is anchored in its vertical position a deck 60 is suitably secured to the top of. the said cylinder to provide floor space for the crew and for placing thereon a balloon 61 secured by a cable 62 to a winch 63. This balloon is used to ascertain weather conditions, wind directions and velocity thereof in the upper air strata.

A pipe line 65 leading from the floor of the deck 60 into the tube 19 provides means for filling same with fresh water and for collecting rain water to be used by the crew for drinking or other purposes. A cock or tap 66 provides means for tapping the said reservoir.

It will be understood that means of egress not shown may be provided between the different compartments in the cylinder, and the compartment 67 may be used for sleeping quarters for the crew and as a radio receiving and broadcasting station, the aerial 68 of which is shown in Fig. 2. A bacon 69 is also shown suitably supported from the deck 60. A mooring mast (not shown) may also be attached if desired.

An oil reservoir 70 (Fig. 5) provided with a pipe line 71 having a valve 72 therein and leading to the exterior of the cylinder provides means for supplying oil to the water in storm weather.

In ig. 4 I have shown a plurality of cylinders 10 supporting a platform 75 adapted to be used as a landing platform for aircraft for repair or refueling purposes.

The c linders are preferably placed in a wedge-1i e or triangular formation, the purpose of this being to deflect the wind and wavesand thereby creating a lee area in the ocean, in the shelter of which a seaplane may descend on the water and ride out stormy weather, after which it may be lifted onto the platform for repair or other servicing.

From the foregoing it will be seen that I have provided a buoyant pontoon-like marine apparatus adapted among other things to be used as an airship sea beacon and service station, to which also a mooring mast for dirigible's may be attached.

It will also be seen that I have provided eflicient stabilizer and anchoring means that will prevent the device from unduly swayin dueto weather conditions.

aving described my invention, what I claim as new and desire to secure by Letters Patent, is
