Definitions

  • the present invention relates to a shrouded impeller type, hydraulic jet propulsion unit and attachment apparatus for converting a propeller drive to a propulsion system.
  • the present invention relates to improvements in jet propulsion apparatus and is concerned more particularly with attachment apparatus to be substituted for the propeller of a rnarine motor whereby to convert the same from a propeller drive to a jet pump propulsion system.
  • the principal object of the present invention is to provide a jet propulsion unit which is adapted easily to be substituted on the drive shaft of an outboard or inboard marine motor when the propeller is removed and which will require for its operation no modification of the motor cooling system, exhaust gas flow or any internal gearing. Further, it will require no alteration of the steering wheel or cable arrangement or throttle or gear shift linkage arrangement for forward or reverse.
  • Illustrative of the ease of installation of the jet unit after the propeller and its shear pin has been removed is the fact it is only necessary to secure the fixed portions of the unit to the conventional motor gear case seal plate and to secure the rotor to the motor shaft by another shear pin. Also, the unit may as easily be removed and the propeller replaced whenever desired.
  • FIG. 1 is a representation of a conventional outboard motor showing the jet propulsion unit of the present invention attached to the bottom portion thereof in place of the conventional propeller, it being understood, how ever, that the jet propulsion unit of the present invention is also adapted for attachment to inboard-outboard motors;
  • FIG. 4 is a sectional view taken on the line 4-4 of FIG. 3 and looking in the direction of the arrows;
  • FIG. 6 is a sectional view taken on the line 6-6 of FIG. 3;
  • FIG. 7 is a sectional view taken on the line 7-7 of FIG. 4;
  • FIG. 8 is a view similar to FIG. 4 but showing a modified form of that part of the invention.
  • FIG. 9 is a sectional view taken on the line 9-9 of FIG. 8.
  • FIG. 10 is a sectional view taken on the line 1010 of FIG. 8.
  • the jet pump device 10 comprises, as; best shown in FIG. 3, a shroud 12 having at its forward end a concentric mounting collar 14 carrying on its periphery a radial array of streamlined struts 16 and secured to the shroud 12 in any suitable manner such as by the screws 17.
  • a runner or rotor 18 which includes a hub 20 and a series of propelling vanes 22 follows the mounting collar 14 and struts 16 within the shroud 12.
  • a stator 24 having a streamlined afterbody 26 and a series of flow-straightening vanes 28 follows the rotor 18 within the shroud 12.
  • the shroud 12, rotor 18 and stator 24 and their respec tive parts may be formed by sand-casting or die-casting or in any other desired manner preferably of materials known to provide the required strength and seawater corrosion resistance.
  • the rotor or runner 18 is positioned in axial alignment with the drive shaft 30 by a hub plate 3 4 and receiving hub 36 surrounded by a flexible liner 38 coaxially positioned by dowel pins 4-0 and a hub nut 42 in threaded engagement with the hub 36, as shown in FIG. 3.
  • an annular bearing 44 is positioned in the afterbody 26 of the stator 24 for receiving the extended free end portions of the rotatable hub 36 and. shaft 30 which are interconnected by the shear pin 46.
  • the screws 17 are threaded into the peripheral extremities of the struts 16 of the mounting collar 14, either directly or through a surrounding ring structure, solidly to secure the unit 10 in axial flow alignment with the motor drive shaft. It will be noted that the unit provides for full directional control in forward and reverse just as with the original propeller and a forward facing intake scope for maximum propulsive efficiency.
  • 114 represents the concentric mounting collar and 116 the streamlined struts.
  • the struts or spokes are greater in number, such as the eighteen shown in FIG. 8 as compared with the eight shown in FIG. 4 and under certain circumstances provide for greater protection particularly when the unit is used by swimmers or water skiers.
  • the mounting collar 114 of the modified mounting plate may be secured to the after seal plate by the same bolts 32 as shown in FIGS. 3 and 4-.
  • Thrust is imparted to the boat to which the motor is attached in accordance with the equation:
  • a concentric rotor including a hub and a plurality of radial propelling vanes disposed within the shroud between the mounting collar and stator and adapted for connection to said shaft for rotation therewith, and
  • the rotor includes a hub plate, receiving hub and a threaded hub nut for positioning the rotor in axial alignment with the shaft.
