SEAPLANE FLOAT Filed Sept. 30, 1927 IN VENT Owl.
CARL. D. Hem .512,
J3: Mam/e 4 Patented Sept. 17, 1929 UNITED STATES CARL D. HOLLER, OF SEATTLE, WASHINGTON SEAPLANE FLOAT Application filed September so, 1927. Serial no; 223,087.
This invention relates to seaplane-pontoons or floats and wingtip floats.
One of the objects of this invention is to reduce the impact or concussion between a float and the water surface when a seaplane alights on such a water surface.
Another object is to provide a float with a flat boat bottom embodying keel-like edges.
Another object is to provide keels along the opposite longitudinal sides of a float bot tom with the bottom hollowed to form two distinctly shaped heels in the bottom of the float.
Other objects will appear from the following description and appended claim as well as from the accompanying drawing in which Fig. 1 is a top plan view of a float indicating in dotted lines the two keels below the hull on the opposite longitudinal sides of the hull according to this invention.
Fig. 2 is a side elevation of the float illustrated in Fig. 1. I
Fig. 3 is a cross section of the float on line 33 of Fig. 1.
A float or pontoon is preferably provided with a broader bottom than a common boat since this acts more favorably to balance and support a hydroaeroplane. However, on
alighting the impact or concussion is liable to jar the hydroaeroplane itself and especially the delicate machinery and instruments required and needed in a hydroaeroplane.
It is well known that a V-shaped bottom is less liable to affect a hydroaeroplane than the flat-bottomed floats. I
By combining V-shaped andflat bottomed structures the advantages of both structures are made use of.
The invention disclosed herewith is there fore principally designed to advantageously support a hydroaeroplane.
The sides 4 of the float-body 5 are slanted 7 inwardly as illustrated in Fig. 3 in the drawing. These inclined sides 4 togetherwith the lowermost portions 6 of the hollowed bottom 7 are so designed that two distinct V-shaped boat bottoms are embodied in the float as a whole.
two heels comes to restupon the water or into full contact with the water, this structure acts very similar to a common flat bottom floatjit will easily skip over the water i surface and more readily rise from the water than a plain V-shaped bottomed float.
To further improve the riding and sup-. I porting of this float the whole bottom is designed along the lines of a race boat.
The front portion 8 of the bottom is there-.
fore set off as indicated at 9 in Fig. 2 with the rear portion of the bottom gradually ris-' ing from this set-ofl as indicated atlO. The 7 rear end 9 of the lower bottom portion is provided with an overlapping edge 11 to increase the lifting capacity of the float, inasmuch as an air pocket is formed in the space between the overlapping edge 11 and the upward extending rear bottom portion lO-be hind the rear end 9 of the lower bottom por 'tion 8.
For stabilizing'and further increasing the carrying capacity of this float the sidewise projecting fins 12 are provided along both sides of the float from the stem end 13 to extend to the rear end of the float where this rear end rises above the water surface as in dicated at 14;. The float-body as well as the fins are provided with partitions or bulkheads 15 for reinforcingthe structure and to facilitate a control of the float in case of leakage.- l I I o The fins 12 serve to add to the floating ability of the hull, to provide stabilizingmeans laterally and longitudinally while at rest in the water, to eliminate wingtip floats.
which cause a great deal of head resistance and to deflect the spray of the waterwhile taxiing.
Having thus described my invention, I claim:
A seaplane-float having its bottom set ofl to form a front bottomwith adeeper draft than the rear bottom portion, the front bot tom portion being provided With a V-shaped keel along both longitudinal sides from the stem end to the rear set-ofi' end of the front bottom portion and designed so as to form a hollow straight bottom between the two keels, the sides of the float being inclined from the Water line inwardly and the lower portions of the inner hollowed bottom being inclined in the opposite direction to form comparatively evenly V-shaped keels,. and fins on both opposite longitudinal sides of the float above the Water-line sharply set oti' from the inclined outer sides of the float.
In testimony that I claim the foregoing as my invention 1 have signed my name.
CARL D. HQLLER.
