Definitions

  • the invention relates to a driving system for boats, which also serves as a steering and braking device.
  • a compressed-air aggregate is used, conventionally including a diesel motor, compressor and compressed-air tank or tanks.
  • compressed-air nozzles are provided, preferably below the floating line, so that the boat is propelled by the pressure of the compressed air emerging from the nozzles.
  • the compressed air can also be used for braking the forward movement of the boat.
  • the invention sets in and has as its object a system of nozzles swingable about a substantially vertical axis to the left and/or the right, thereby changing the direction in which the compressed air is expelled, and thus providing a change in direction of the boat. It has been found that the boat promptly reacts to the change in the angular direction of the nozzles so that the most difficult maneuvers and movements can be carried out with relatively small turning circles. Steering throttle valves are dispensed with, and the compressed-air conduits need only be provided with simultaneously operable throttle valves for controlling the speed of the boat.
  • the swingable nozzles are formed by air-tight articulations having pulleys or sprocket wheels about which a control cable or chain is guided, preferably about both articulations, and which cable or the like is eventually connected to a conventional steering wheel or the like at the control position (e.g., dashboard) of the boat.
  • the stern of the boat has substantially horizontally arranged, watertight recesses in which the nozzles can freely move in their horizontal plane of swinging action.
  • two further, stationary nozzles can be provided in the bow of the boat, similarly below the water or floating line thereof, and at a level corresponding to that of the swingable nozzles in the stern.
  • These stationary nozzles are adapted to brake the forward movement of the boat, if necessary, and they will of course also allow rearward movement when the other nozzles are fully throttled.
  • the stationary noules are preferably lodged in suitable recesses of the bow so that they do not protrude beyond the contour of the boat. These recesses can be closed by the aid of movable flaps so as to reduce resistance to the water during the forward movement of the boat, by the aid of conventional control means which allow selective opening and closing of said flaps, such as from the dashboard.
  • the invention also contemplates a double bottom for the boat which can be filled with a floatable material such as cork, or which can be lined with cork mats and the like.
  • FIG. 1 constitutes a somewhat schematic plan view of a boat equipped with a compressed-air drive system as well as the steering and braking system combination according to the invention, the middle portion of the boat having been omitted for the sake of clarity;
  • FIG. 2 is a rear view of the stern, showing the inventive swingable nozzles
  • FIG. 3 is a front view of the bow, showing the optional stationary nozzles behind closable flaps.
  • the bow and the stern of the boat are generally designated by respective numerals l and 2; in P10. 1, the latter is only shown in dot-dash lines since the actual configuration thereof is not critical as far as the inventive concept is concerned.
  • the water or floating level is arbitrarily indicated at WI. but could be higher, or somewhat lower, than shown, as long as the compressed-air nozzles are therebelow.
  • the omitted middle portion of the boat lodges conventional equipment for producing, storing and dispensing compressed air, such as, for example, a diesel aggregate; air tanks are shown at 30 and 3b (for the bow and the stern, respectively).
  • Numerals 4a, 4b denote conduits leading from the tanks to the nozzles to be described hereinafter in full detail.
  • nozzles 5b which have articulated conduit sections 6, allowing angular movement of the terminal nozzle section, about an angle identified by a and which, for practical purposes, is 45 or more (in the illustrated embodiment,
  • the articulation has rigid therewith a pulley or sprocket wheel 7 for guiding therearound an endless force transmitting means in the form of a cable or chain (as shown), numbered 8, the latter being guided about rollers or pulleys 9.
  • the dashboard 11 is shown to include a steering wheel 10 about which the chain 8 is guided so that movement of the wheel in either direction will entrain the chain as well as the articulated conduit sections 6 with their pulleys or wheels 7.
  • a simultaneous swinging movement of the nozzles 5b results from the actuation of steering wheel 10, thereby directing the stream of compressed air in the proper way for the desired maneuvering of the boat.
  • the transmission between the swingable nozzles or their swingable portions can be of any desired and known kind although only one preferred embodiment thereof has been illustrated herein.
  • a rigid linkage or other connection can be provided between the swingable nozzles and the steering means (not necessarily a wheel).
  • FIG. 2 shows that the stern has therein substantially horizontal cut-outs or recesses 12b wherein the nozzles 5b can be swung in a horizontal plane.
  • Proper airand water-tight members are used to insulate the system against unwanted water from entering and compressed air from escaping.
  • a manual control member 13 is schematically shown, acting upon Bowden-type or other cables 14 which in turn control respective throttle valves 15 in the conduits 4b.
  • the throttle arrangement is independent from the speed control so that speed can be regulated regardless of the direction in which the boat moves.
  • nozzles 50 which are directly attached to their conduits 4a.
  • Throttle means have not been shown for these nozzles but it should be understood that they can be activated independently from the swingable nozzles 51:; if necessary, individual throttles for the leftand the the maneuverability backward travel.
  • FIG. 3 shows how the bow is provided with cut-outs or recesses 11a which lodge die nozzles a.
  • These recesses have movable flaps or covers 224, shown withdrawn or open on the left-hand side of this figure, and closed on the right-hand side (and similarly in the plan view of FIG. I).
  • These flaps may be guided along rails, may be pivoted or otherwise movable, and constructed in any other manner known for structures of this kind. In their closed condition they reduce resistance of the boat to water when moving in forward direction.
  • Conventional control or actuating means for the flaps have been omitted for the sake of clarity; a cable or a linkage may lead to the control position at the dashboard of the boat.
  • the nozzles 50, 5b have been shown in a recessed arrangement, not protruding beyond the contour of the boat. It is however possible to have the rear or the front noules, or all, protrude beyond the boat walls in which case the recesses would not be necessary (or only in the bow to allow the nozzles to be covered up).
  • FIG. 2 shows the expedient provided for this urpose, namely a double bottom 16 which can accommodate float/able materials, such as cork and the like, shown at 17.
  • the boat bottom may also be lined with cork mats and the like.
  • the double bottom may extend partly or completely along the boat.
  • the inventive combined driving, steering and braking system has the advantage that the boat reacts promptly to even the slightest movements of the steering wheel '(that is, the angular movements of the stern nozzles) without individually throttling them.
  • the boat can turn to either side, regardless of the required turning angle, almost on the spot, and without substantial loss of speed. Both braking and backward travel are possible in an expedient manner since the speed control is independent from the directional control.
  • Boats equipped with the inventive system are most suitable for sporting purmsy also be provided right-hand nozzles 5a, thereby increasing of the boat in docking operations or for poses, for life-saving and patrol work, and other purposes where speed and efiiciency are required.
  • a combined driving, steering and braking system for boats comprising in combination means for producing, storing and dispensing compressed air, and rearwardly directed compressed-air nozzles in the stern of the boat, operativeiy connectable with said compressed-air means, and having terminal portions swingable in a substantially horizontal plane, by the intermediary of respective articulated conduit sections, the latter being connected by the aid of transmission means to manual steering means at a control position of the boat, for controlling the swinging movement of said nozzles and thereby the direction of movement of the boat, as well as forwardly directed stationary compressed-air nozzles in the bow of the boat, operatively connectable with said compressed-air means, and adapted to brake the forward movement of the boat and to provide rearward movement if necessary, said stationary nozzles being lodged in recesses provided in the bow of the boat, and further comprising movable flaps for said recesses, and control means for selectively opening and closing said flaps from the control position of the boat, thereby reducing resistance to the water during the forward movement of the boat when
  • both said rearwardly and said forwardly directed nozzles are disposed substantially at the same level, and wherein at least said rearwardly directed nozzles are positioned, with their swingable portions, so as to be within the contour of the boat.
  • said transmission means includes force transmitting means operatively interconnecting said steering means with portions of said articulated conduit sections for simultaneous swinging movement thereof about an angle of at least 45.
  • said compressed-air means includes throttle means providing speed control for the boat, operable independently from said steering means and the prevailing direction of movement of the boat.
