LANDING FLOAT.

Application filed November 30, 1927. Serial No. 236,789.

The present invention relates to landing floats to be used principally for the landing of aeroplanes in mid-ocean or on other large bodies of water..

Objects of the invention are to provide a float of the above character which will be stable in construction and which will be maintained in proper position for the landing of aeroplanes thereupon and willbe insured against overturning or sinking due to the stress of the waves or other factors.

Other objects and advantages will appear from the following specification and will be set forth in the subjoined claims.

In the drawings which constitute a part of the present specification:-

Figure 1 is a side View of a float built in accordance with the principle of my invention.

Figure 2 is a plan view of the same with parts being broken away on line 22 of Figure 1 to show the internal structure thereof.

Figure 3 is a view partly in section and 2 as seen looking in the direction of the arrows on line 3-3 of Figure 2.

Figure 4 is a fragmentary view in section on the line 4l4 of Figure 2.

Referring to the drawings in detail by reference numerals, the same numerals designating the same parts in all views of .the drawings, 1O designates a plurality of floats which may be constructed in dry dock and towed out to sea and then connected together by a superimposed structure, consisting of longitudinally and transversely extending I beams 11 and 12, supported in spaced relation above the floats by means of seamless steel tubes 13 and connected to 40 gether in any suitable manner'as by welding or by rivets. Suitable brace members 14; are providedbetween the upper I beams 11 and 12 and the tops of the floats, said braces being arranged at an angle of 45 or some such suitable angle to the floats and to the frame comprised of the members '11 and 12. The grill work formed by the crossing of the beams 11 and 12 provide a support for a surfacing of deck plates 15 which is preferably of sheet steel and with which.

it is contemplatedto cover the entire top of the landing float which when so covered presents a flat surface. Placed upon the steel plates is a surfacing 16 which may be of asphalt or any suitable material designed .ito shed water from the field and to give a proper landing surface for an aeroplane or the like. The superstructure comprising the members 11, 12, 13 and 14 is further closed at the top and water rises therein under the head of floatation. The rocking of the structure by wave action is reduced by the resistance of air against the water in the cups.

The tubes 13 are referably extended downwardly through the tops of the floats and are connected at their lower ends with transverse I-beams 19 extend'gg transversely of the float. Brace members may be provided between the upper adjacent edges of the floats and the tops of the tubular members 13 adjacent the ends of said floats as shown in Figure 1 of the drawings. The superstructure is made with the sides and ends thereof sloping toward the center in an upwardly direction shown in Figures 1 and 3 and the whole assembly isof such weight that the water line will be sufficiently above the floats to entirely submerge the same and insure against the overturning of the float. .The cups 18 as indicated in Figure 3 act to admitpartial rise of water in their lower ends thereby promoting the stability of the device.

Having described my invention, what I claim is 1. A float'of the character described coma plurality of air tight compartments formmembers with the float compartments, brace ing a partly submerged raft, distributed members connecting said longitudinal and rows of air cells therein, a superstructure transverse members With the float, and a 1 connected thereto and comprising members landing surface for aeroplanes at the top extending longitudinally and transversely of said superstructure.

of the float compartments, tubular members In testimony whereof I affix my signature. connecting said longitudinal and transverse EARL D. VAUGHAN.
