  • the outboard propelling system is AN ADJUSTABLE PROPELLER secured to the inboard engine which has its shaft coaxial with 1 Claim, 6 Drawing Figs. the input drive shaft of the outboard propelling system. This input shaft extends through a hole in the stern board of the [52] U.S.Cl 115/35 boat and is driven synchronously with the engine Speed by lnt. means of an engageable and disengageable clutch p d 86% 5/06 between said shafts.
  • the inboard drive shaft transmits torque ofSearch l means of a mechanical transmission to a horizontal 41 propeller unit rotatably mounted in the lower portion of the outboard propelling system.
  • the propeller has a plurality of [56] References C'ted blades adapted to be turned between two end positions for al- UNITED STATES PATENTS ternative ahead and astern propulsion of the boat, the blades 2,809,605 10/1957 .Russell ll5/34X being hydraulically operable by a piston rod displaceably 3,148,735 9/1964 Miller et a1.
  • This invention relates to a driving mechanism for high speed, comparatively large boats having an inboard suspended engine and an outboard propelling system.
  • the invention relates to such driving mechanisms in which steering of the boat is effected by turning the outboard propelling system about a substantially vertical pivot located outside the stern board of the boat and wherein the outboard propelling system is also adapted to be turned backwards in the direction of the course of the boat about one or more horizontal pivots.
  • Outboard propelling systems of this kind have previously been constructed for comparatively small boats having an engine power of between 50 and 150 HP.
  • development has tended toward ever increasing sizes of boats, and the demand for outboard propelling systems for comparatively large pleasure boats, taxi boats and similar transport boats and landing boats for naval purposes has increased enormously during the last decade.
  • an outboard propelling system considerably reduces the initial costs as compared with a conventional inboard installation in which a propeller shaft below the boat is connected to the engine via a bevel gearing or the like.
  • an outboard propelling system has considerable advantages from the point of view ofhandling and maneuvering and thenavigability of an outboard propelling system-equipped boat in shallow water is superior to a boat having firmly attached drive members. Since the outboard propelling system usually is adapted to be turned backwards in the direction of course of the boat. damages to this system in case of grounding are eliminated or mitigated. If, nevertheless, the propeller casing or part thereof should be damaged the propeller assembly of most of the prior art outboard propelling systems can easily be turned upwards above the water line and exchanged or repaired.
  • propelling systems usually include some sort of a reduction gear which via a vertical drive shaft transmits the engine power to a propeller shaft which indirectly carries a propeller with a plurality of fixed blades.
  • the direction of rotation of such a propeller must be reversible for alternative ahead and astern propulsion of the boat.
  • prior art propelling systems are equipped with a reversing gear and a friction clutch or the like between the engine and the propelling system.
  • the object of this inventjonjs to provide easy maneuverability of relatively large high-speed boats having a power requirement between 100 and 300 HP with the use of a single driving mechanism comprising an inboard motor and an outboard propelling system.
  • the invention is characterized by the combination of the following features:
  • the outboard propelling system is firmly attached to the inboard suspended engine the shaft of which is coaxial with an input drive shaft of the propelling system, which input shaft extends through a hole in the stern board ofthe boat and via an engageable and disengageable clutch disposed between said shafts can be specded synchronously with the engine speed;
  • the inboard drive shaft transmits torque via a mechanical transmission to a horizontal propeller unit rotatably mounted in the lower part of the propelling system;
  • the propeller has a plurality of blades adapted to be turned between two end positions for alternative ahead and astern propulsion of the boat, said blades being hydraulically operable by a piston rod displace-ably mounted in a portion of a propeller shaft which portion is in the form of a hydraulic cylinder.
  • the invention results in the advantage that the engine can be elastically suspended in the engine bed resulting in a more silent and smooth operation of the engine.
  • the stern board is relieved and the reaction pressure of the propeller is taken in the engine bed in a combination according to the invention.
  • the engine is preferably a diesel engine which reduces the danger of tire onboard the boat and results in lower operating costs and higher reliability in operation as compared with a petrol engine.
