Abstract

707,638. Screw propellers. THORNYCROFT & CO., Ltd., J. I., and PARSONS, F. G. June 1, 1951 [March 9, 1950], No. 5959/50.. Class 114 . A self-propelled ship has auxiliary screw propulsion means comprising a longitudinally disposed auxiliary propeller shaft or shafts 4 driven by an auxiliary power plant 6. The auxiliary screw propellers 4a, 4b, are adapted to be shut off from the flow of water when inoperative. The auxiliary propellers may be mounted in tandem on a common shaft 4, which extends rearwardly of the main propellers 2, and are housed in a stern tunnel or tunnels 3b each having a sloping entrant portion 3a and an exit portion 3c with a slight downward slope. The tunnel has a fixed bottom plate 8 and hinged doors 7, 7a which are operated by screw jacks. According to the Provisional Specification the tunnel outlet may also be closed by a sliding door. The auxiliary power plant 6 may be a steam, petrol, or Diesel engine or an electric motor. Two or more auxiliary screw propulsion means may be employed.
