Definitions

  • the invention is based on appreciation of the fact that these disadvantages can be avoided and a considerable increase in velocity can be attained without over dimensioning the motive system if the swinging stern of the ship'itself is made in one piece from an elastic material such as rubber and/ or has at least one elastic longitudinal member extending throughout its entire length, so that the stern forms an even continuation on all sides of the substantially inflexible remaining portion of the hull, at
  • the longitudinal member can be an extending leaf spring, e.g. a central steel plate, or an ash wood spring.
  • the elastic stern of the invention acts as does the tail fin of a fish. The eificiency of such a drive is better than that of the usual ship constructions, as evidenced by comparing the highvelocities of small fish.
  • Figs. 9 andxlO represent a further modification of the tail
  • Fig. 11 is a longitudinal sectional view along the lines of Fig. 3 showing the dis? position of the eccentric masses. 7
  • the streamlined hull 1 the upper portion of which has bullseyes 2 above the water line 3, is closed at the rear by a transverse wall 4.
  • the elastic stem 5 is attached to this wall, which stern tapers rearwardly and the outer faces of ,which are flush V in Figs. 3 to 6, namely, at least one longitudinal leaf spring 7 surrounded by an elastic filler 8,. preferably of soft rubber, and an outer shell 9.
  • the spring has anopening 10 (Fig.
  • Steel stays 14 preferably are provided to strengthen the cavity, in particular between the points of mounting of the drive mechanisms. These stays are likewise mounted on the leaf spring 7 by guide elements 13. As-
  • Fig. 6 they may be'single limbed and arranged oppositely off-set on both sides of the longitudinal memher, or they may have two arms.
  • Figs. 7 and 8 show a different embodiment of the invention, in which the stern comprises several elastic longitudinal members 15 formed'from spiral springs,
  • A. barrel-shaped spiral spring 16 within a filler forms the elastic longitudinal member, which tapers rearwardly and leaves a cavity in the centre for mounting a drive mechanism of the kind indicated. As shown in Fig. 10, the motor is suspended from the turns of the them. This necessarily results in an uneven surface which causes the oscillating action of the tail members to be unharmonic.
  • the motor is suspended from the turns of the them.
  • Rudders or fins always have a very small thickness. Thus, strong eddies are created and the efficiency is low.
  • a smooth, uninterrupted outer surface and an even course of the stern are ensured, which closely resembles the example set by nature and results in an improved efliciency.
  • Figures 1 and 2 are a plan-and side elevation of a speed boat;
  • Fig. 3 is a longitudinal secspring anddirectly transmits the oscillations to the tail.
  • This embodiment is simple and strong- It has the advantage that stays as shown in Fig. 6 are eliminated.
  • the attachment of the stem to the other part of the hull can'be preferably by way of fastening elements embedded or moulded in the stern.
  • the outer shell consists of a tight, wear-resistant rubbery material which is joined to the softer filler e.g. by vulcanizing.
  • the elastic stern constructed according to the invention results in a favourin area from its forward end a ft at least below the water 7 line, and a propelling mechanism associated with the stern part and acting only in the forward part of the stern part.
  • a ship structure comprising a hull including a fore part and an oscillatable stern part connected to the fore I part, said stern part being of elastic one piece material v pelling mechanism being, an electric motor mounted in such opening for movementlengthwise of the opening.
  • a ship structure as claimed in claim 6 further including stays fastened to the said leaf spring and bracing the said opening.
