Definitions

  • the present invention relates to all surface vessels propelled by the reaction of a water jet.
  • the device of the invention adapts to all hull shapes and allows, by a sir.ple rotational movement, all maneuvers both forwards or backwards and towards the sides; it can be controlled by a known rudder control system.
  • the device of the invention comprises the following main parts: a) a cylindrical tube (1) constituting a passage through the hull or through a part adaptable to the transom of a hull, as shown in Figures 1 and 2 of the middle plank; the tube (1) serves as a guide for the piece (2); the lower end of the tube (1) is cuvée outside the hull; the upper end is open inside the hull, above the waterline; the axis of the tube (1) is located in a plane parallel to a vertical plane parallel to the axis of the shell; it forms an angle of about twenty degrees with respect to the vertical, oriented so that the top of the tube ("]) is inclined towards the front of the cuckold.
  • tail d 'ejection a piece of piping (2) called" tail d 'ejection "; it is bent at an angle of about one hundred and ten degrees; the necessarily cylindrical upper part follows the inner wall of the tube (l); it projects above the tube (1) of sufficient length to receive the device rotation control, as well as the retaining device which bears on the upper end of the tube (l); the lower part consists of the elbow and its extension; it is located outside the tube (1) and can take any form useful for the efficiency of the propulsion and the direction of the ship; it comprises a flange forming a stop, which rests on the lower end of the tube (l); it comprises a fixing point for rigging a emergency command or to receive a rope retaining e during disassembly of the ejection tail.
  • a piece of piping (3) intended for connection of the device of the invention to the water delivery pipe for this propulsion; this part necessarily includes a cylindrical part which engages in the part (2) from above and of which it marries the inner wall; it comprises a collar forming a stop which bears on the upper end of the tube (2); the part (3) is fixed and hand held in position by an appropriate device.
  • a piece retaining device (2) which is fixed on it; e) a device for controlling the rotation of the part (.2), pulley or toothed wheel, and the like; it is fixed on the part (2) directly or indirectly.
  • the device of the invention is particularly recommendable for boats called to navigate near swimmers or in waters containing objects likely to cling to the propulsion or steering gear, such as ropes, nets, grasses and coetera.
