The floats, which are generally designated by 3 in Fig. 1, may, according to the invention, be ar preferably of spherical, conical or bottle-shape and may be rigid hollow bodies or inflatable and wholly or partly elastic, so that they can be given The invention likewise consists in that the means forgsupporting the float chains relative to> Wire and offering little resistance to the medium L: 20 tire length at points situated relatively far apart. yet afford a ñrm support. va0 15 carrier frame. ^ 40 -thus assembled presents the least possible re sistance to the medium (air and possibly water in the case of high seas) to be cleaved when the craft is travelling. Such lattice Work sections 45k formed of stays and stretched Wire have a great compression strength, and as they, at the same time, offer but slight resistanceto the medium, are also particularly suitable for the carrier frame. They are cheap to build and of -com 50 paratively light weight. A carrier frame I com posed of such structures is illustrated in all the examples shown in the drawing and can be seen most clearly in Fig. 4. In Figs. 2 and 3 spherical floats I0 are pro 55 2""' " 2,120,591 "z vided which are threaded on ropes II in such a manner that they can rotate thereon. The ropes are yieldably stretched so that the floats I0 are capable of limited movement in all directions. They can move both in vertical and also in hori Zontal direction and thus follow the movements of the waves to a limited extent. The ñoats I0 are arranged in parallel rows in longitudinal di rection underneath the carrier frame I, the rows of chains being subdivided into sections I2 and I3. The individual float chain sections l2, I3 may be yieldable along their length at inter vals by stays, should the length of the carrier frame so require. Such intermediate stays are 15 indicated in Fig. 1. Fig. 5 shows a similar arrangement to Figs. 2 and 3, but the iloats I4 are of bottle- or conical~ shape. , Fig. 6 shows in plan View an arrangement of 20 the float rows in which the ñoat chains con verge at I5 at the bow of the carrier frame, in stead of extending parallel along their entire length, Whereas the rear chain sections are ar ranged in three parallel rows along their entire 25 length.AV ~ v ' I claimz-Á _ _ _ _ _ _ 1.
