This invention relates to an improved land` field or platform for use on the high seasv in the nature of a portable float.

a novel cellular concrete structure equipped with suitable appurtenances and ,accommoda-` tions and characterizedprimarily by a huge platform functioning as a novel landlng field for airplanes and the like.

I 'have been inspired to developing the 1nventive conception to provide a strong and dependable structure possessmg many features of merit from agstandpoint of use, and an equal number of advantages from a standpoint of economical construction. Q

The various devices and features constituting the cardinal factors of importance will become more specifically evident and under; stood from the following description and drawings..

, The drawings, though somewhat dlagrainmatic in general principle will suiice to give a pictorial illustration of the fundamental parts and means thought necessary in the de-V velopment of a practical assembly.

In the drawings: Figure 1 is a top plan view showin the preferred configuration and the approximate A relative positions of certain of the features.

Figure 2 is a side view of Figure 1. Figure 3 is -a transverse vertical section taken on the plane of thew line 3-3 of FigiA pendicular constructionalunit Figure 8 is a cross section through one of said units.

Figure 9 is a longitudinal sectional view therethrough. I

The structure may well be assembled and constructed on the bank of a suitable body of water. I have found it practical and economical to accomplish this by building a dam at the mouth of an/ appropriate tidewater inlet or small bay which preferably has a normal nine foot high water mark.

The trapped water is pumped out and the ground'graded to the desired proportions and shape. This graded area of ground is covered or coated with cement to provide a suitable base or concrete foundation to vaccommodate the attendants, workmen and apparatus employed for complete building purposes.

The'marginal portion of the float may be constructed from precast'concrete units but is preferably made from units cast on saidconcrete foundation. As seen in Figure 3, there are two sets of perpendicular or vertical unitsy and each unit is broadly designated by the numeral `10 and as seen in Figures 8 and 9, the unit is hexagonal in cross sectionalshape and provided with internal reinforcing spiders 11.

For sake of distinction in Figure 3 the marginal units are distinguished by the numerals 12 while the shorter nucleus units are denoted 75 by the numerals 13. The shorter nucleus units co-operate with the main top or platform 14 and an appropriate arrangement of partitions 15 in defining a multiplicity of general utility compartments 16.

I have not attempted to detail the various compartments. in shape, it being understood v'that these will be longitudinally and transversely disposed and that the main central corridor from which the other corridors and 5 passages branch will be provided with appropriate entrances having removable trap `doors or closures17, as seen for example in Figure 1.

This assemblage of hexagon unitslO prosealed or fastened together so as to provide a substantially fiat bottom. The marginal' edges of the outermost unit may be cement filled, so that the longitudinal side walls and stern will be substantially fiat.

The bow of the fioat is generally distinguished .by the numeral 18 and as illustrated in the drawings substantially semi-circular in configuration. It is so constructed as to provide a multiplicity of companion teeth 19 which function to rovide a Inovel breakwater. The pointe ends of the teeth are preferably disposed so as to occupy a plane elevated above the bottom of the structure and to assume a level substantially even with the normal low-water line, this being desirable to facilitate navigation and to allow the float to ride the waves, so to speak.

The spaces or grooves betwen the teeth are shown in Figure 4, the lower groove 20 being substantially shallow and the upper groove 21 much deeper. The grooves 20 facilitate the aforesaid riding action while the grooves 21, serve as inlets for conducting the surface water and waves into a segmental channel 22 which functions as a trough and which-discharges the overow water into a multiplicity of radial ducts 23 formed in the structure and communicating with an open bottom perpendicular chamber 24.

There is a suitable bearing 25 in this chami ber to accommodate a shaft 26 carrg'ing a propeller 7 of appropriate form, sai propeller and shaft serving as a source of power to operate an electricity generator 28 in the closed frontal compartment 29. Obviouslyl the generator is employed for various power purposes.

For example, on the aft of the float may be one or more beacon lights 3.0 to facilitate taking off and"landing of planes. At the stern of the oat I provide a gang of electric motors 31 having retractable propellers 32 arranged for propulsion purposes, said motors being supp ied current from the aforesaid generator 28.

In one of the compartments designated by the numeral 33 in Figure 4, I provide one or more sheaves 34 to accommodate a windlass cable 35 for an anchor 36 (see Figure 5 also).

. I also call attentionto the numerals 37 which designate wells to accommodate lee boards 38 raised and lowered by suitable hoisting means (not shown) to serve as baliies to avoid 4undue side drift of thesiioat.

AIt is obvious of course, that the float as a'- u'nit is capable of propulsion from place to motors and propellers. Y

To` further facilitate the navigation I proplace through the provision of the electric vide sailsandsuitable rigging and in this con- 05neetion I-invite attentionto Figure 6. In l'ection of said overflow water, saldfrontal this figure it will be observed that the numeral 39 designate recesses at one end of which are formed countersunk ockets 40. Pivotally mounted as at 41 in t e pocket is' a mast 42, the mast being retained in erectposltion by removable pins 43 fitting into an associated socket in one wall of the pocket.

The numerals 44 designate stays having adjustable turnbuckles 45. These masts serve to accommodate sails (not shown) or wireless apparatus, and when not in use are allowed to fold down into the recesses 39.

Through the medium of proper adjustment of motor driven propellers and sails and rig-4 ging, it is evident that the structure maybe moved from place to placeor when it has drifted from its predetermined point of anchorage, can be returnedl to said' point for dependable landing conditions. The sails and rigging will also be found desirable in stormyweather.

Many other desirable features for aocom- -modation and safeguard may be provided in actual practice in order to add to the renements and improvements of the structure as a whole. foregoing description and drawings will sufice to give the reader a clear impression and understanding of the fundamental parts and essent al features believed to be necessary in providing a practical water landing field for aircraft.

It is believed however that the It is thought from the foregoing descripi tion that the advantages and novel features of the inventionwill be readily apparent.

It is to4 be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended. claims.
