FLOAT AND Trzn LIKE.
Application filed March 17, 1928. Serial No. 262,394.
The invention relates to floats and the like and the object of the invention is to'provide a fioat adapted to support the hull of a boat or a similar load.
A further object of the invention is to provide a iioat adapted to carry a comparatively heavy load in relation to its size.
A still further object of the invention is to provide a float having a very great buoyancy and stability, it being practically impossible to upset said float.
Other objects of the invention not specifically mentioned will be easily ascertained and understood from 'the following description and the accompanying drawings forming a part thereof. It is however to be understood, that th-e invention is not to be limited or restricted to the exact formation and construction shown in the drawings and described in the specification, but that the invention is only to be limited by the scope of the claims appended hereto.
In the drawings: Y
Fig. 1 is a side ViewV of the iioat carrying the hull of a boat.
Fig. 2 is a sectional view taken on line 2-2 of Fig. 1.
Fig. 8 is an end view of-Fig. 1, and
Fig. 4 is a top View of the frame of a slightly modified form of a float according to the present invention.
The main frame of the float has preferably a rectangular shape and consists of a pair of longitudinal members 5 and 6 respectively, and a pair of cross pieces 7 only one whereof is shown in the drawings. Stiifening members may be connected to the different frame members as found desirable and convenient, but since the exact construction of the frame is not a part of the invention, this construction is not described in detail.
As shown best in Fig. 1 the ends of the longitudinal frame members are curved upwardly and adjacent each of its ends each longitudinal member is provided with a hole. Shafts 8 and 9 respectively are received in the corresponding holes and extend crosswise of the float. A pair of bars 10 arepivotally mounted upon the cross shaft 8, one bar adjacent each longitudinal member, and a pair of bars 11 is mounted in the same way upon the cross shaft 9. The bars 10 and 11 are arranged on the cross shafts in such a manner, that each bar is supported intermediate its ends and at equal distances therefrom. Each pair of bars 10 and 11 is connected with each other by means of a pair of cross shafts 12 and 13 respectively, which shall be called float shafts hereafter in order to distinguish them from the main cross shafts 8 and 9. Adjacent each end of each 'Iioat shaft a disc 14: is loosely mounted. A plurality of hollow bodies forming air or float chambers are supported by each pair of discs. Each disc is provided with a plurality of holes 15, which are arranged adjacent the circumference of the disc and are distributed at equal distances from each other. Short shafts 16 are journalled in said holes and the outer ends of said short shafts may be somewhat upset to keep the shafts in place. At its inner end each short shaft carries a circular plate 17 having a channel shaped cross section. Each pair of corresponding plates supports a tube 18. Each tube is fastened to the rim of the supporting plate 17 by means of rivets 19 or the like and between the rim and the tube a packing 2O is provided in order to make the air chamber formed bythe tube and the two end plates airtight.
Underneath the frame two keel blades 21 are arranged. Each blade being fastened to the frame in any convenient manner, but so that it extends 'downwardly of said frame and parallel to the longitudinal members thereof. Preferably each blade is arranged adjacent one of said longitudinal members.
On top of the frame any desired structure 22 may be provided, which is adapted to support a hull of a boat, a platform, or any other means for receiving a load of human beings, material and so forth.
In Figs. 1 and 3 a float is shown having two sets of air chambers fore and aft, each set consisting of a plurality of air chambers. In Fig. 4 the frame supports only one set of air chambers fore and one set aft. The construction of the float shown in Fig. 4: is practically the same as the construction of the iioat described above. The only difference between the two floats is, that in the float of Fig. 4 the main cross shafts 8 and 9 do not support bars 10 and 1l respectively, but that these bars and the float cross shafts 12 and 13 are omitted, so that the discs 14 are mounted directly upon the main cross shafts.
It is easy to see, that-the plurality of air chambers and the manner of arranging these chambers as Well as arranging the keel blades greatly stabilize the float according to the present invention and impart a great buoyancy thereto.
What I claim is:
l. In a device of the class described a cross shaft, a disc loosely mounted adjacent each end of said shaft, each disc having a plurality of holes therein adjacent its circumference, said holes being distributed at equal distances from each other, a short shaft journaled in each of said holes and a cylindrical hollow member supported by each pair of corresponding short shafts, the connection between said cylindrical members and the shafts supporting the same being leakproof.
