Definitions

  • rocker elements are [58] Field of Search 114/235, 236, 70, 2; mounted on a Pushing vessel in the region of Opposite 115 7 lateral sides of the hull thereof and have freedom of turning movement about vertical axes, which turning 5 R f r n Cited movement is resiliently opposed by hydraulic cylinder UNITED STATES PATENTS and piston units acting upon the respective other arm.
  • the present invention relates generally to an arrangement for connecting two marine. vessels, and more particularly for connecting a marine vessel which is to be maneuvered by pushing with another marine vessel which is capable of effecting such pushing.
  • Tug boats and other marine vessels of this type are frequently used not only for pulling of other vessels, but for pushing them. This is particularly true in harbors where it is necessary to maneuver the non-powered vessel into a particular position or location, an operation which cannot be done by pulling it in many instances, so that it isnecessary to resort to pushing.
  • the bow of the tug as the pushing vessel will hereafter be called for convenience
  • the stern of the lighter as the pushed vessel will hereafter be called for convenience.
  • the vessels are then so connected that they can be displaced relative to one another about a vertical axis, which is located at or in the region of the area of contact between the two vessels. This makes it possible for the tub not only to push the lighter but also, by changing its position so that its own longitudinal axis is inclined with reference to that of the lighter, to use the tug as a rudder.
  • first and second block-and-tackle means having first end portions adapted to be mounted on the vessel to be pushed, and second end portions.
  • a pair of rocker elements are mounted on the pushing vessel in the region of opposite lateral sides of its hull for turning movement about an axis, with each of the rocker elements having two arms located at opposite sides of the respective axis and each second end portion being connected with one of these arms.
  • Biasing means acts upon the respective other arm and yieldably resists turning movement of the respective rocker element about the associated axis.
  • the arms are mounted for turning about upright axes, usually vertical or substantially vertical, and the elongation of the arms itself is transversely to the longitudinal centerline of the vessel.
  • the mounting is such that one arm of each rocker extends outwardly beyond the hull, and it is to this arm that one end of the blockand-tackle unit is secured. This means that the blockamount of rolling that might occur and tend to change 7 the tension.
  • the other arm of the respective rocker unit is connected articulately with a cylinder and piston unit, preferably a hydraulic cylinder and piston unit which in turn is secured to the deck of the tug.
  • a cylinder and piston unit preferably a hydraulic cylinder and piston unit which in turn is secured to the deck of the tug.
  • the cylinder and piston units can be much more compact than those known from the prior art so that the arrangement requires substantially less space than was heretofore possible.
  • an appropriate selection of the respective length makes possible a desired degree of force magnification, so that the dimensions of the arrangement can be varied within relatively wide possibilities simply by varying the amount of force magnification and thereby varying the amount of biasing action which is required.
  • one warping block of an associated block-and-tackle unit is connected with the arm of the respective rocker unit which extends outwardly beyond the hull, so that length variations between the pivotal connections of the block-andtackle units to the rocker arm at the one hand and to the stern of the lighter at the other hand, will be reduced appropriately, so that rolling movements between the vessels of large magnitude will result in only small displacements of the rocker units.
  • FIGURE is a diagrammatic illustration of one embodiment of the invention.
  • reference numeral 1 designates a diagrammatically shown tug, for instance a harbor tug which is well known.
  • the tug l is intended for maneuvering a lighter 2 by pushing it, with the lighter 2 being also shown diagrammatically and only fragmentarily.
  • the connection in motion-transmitting relationship can be effected in various ways.
  • the bow of the tug l is provided with a vertically arranged motiontransmitting member 3 which extends into a recess of a traverse member 4 which is mounted horizontally at the stern of the lighter 2 and can shift vertically in this recess, so that relative vertical displacement of tug l and lighter 2 is possible with the motion of the waves.
  • respective block-and-tackle units 5 and 6 which connect the tug 1 and the lighter 2 with one another. In addition, they permit a displacement of the tug l with reference to the lighter 2 about a vertical axis passing approximately through the point of contact between the elements 3 and 4.
  • the multiple block-and-tackle units 5 and 6 have shear blocks which are respectively connected to the stern of the lighter 2 and approximately mid-way of the hull of the tug 1. These shear blocks are designated with reference numerals 7 and 8 and are pivoted as far as possible outwardly away from the longitudinal center line of the lighter hull in order to obtain the displacement of the tug with reference to the lighter 2 (when desired) with minimum possible force.
  • the other shear blocks 9 and 10 are connected to the outwardly directed arms of respective rocker units or elements 1 l and 12, with these extending outwardly beyond the lateral edges of the tug hull.
  • Each of theseunits 11 and 12 is mounted on deck of the tug 1 for turning movement about an at least substantially vertical axis 11a and 12a, respectively.
  • the inwardly directed arms of the units 11 and 12 are each articulately connected with a cylinder and piston unit 13 and 14, respectively, which is advantageously hydraulically operated, preferrably via a pressure equalizing vessel.
  • An arrangement for connecting a marine vessel to be maneuvered by pushing with another marine vessel which is capable of effecting such pushing and has a longitudinal axis, comprising first and second blockand-tackle means having first end portions; a pair of rocker elements mounted on the pushing vessel remote from the vessel to be pushed in the region of opposite lateral sides of its hull for turning movement about an axis, each of said rocker elements having two arms located at opposite sides of the respective axis and of which a first one extends outwardly away from said axis and a second one extends inwardly towards said axis, each of said second end portions being connected with one of said first arms; and biasing means comprising fluid-operated cylinder-and-piston units extending longitudinally of said axis and each being connected with one of said second arms and yieldably resisting turning movement of the respective rocker element about the associated axis so as to normally maintain said rocker elements extending normal to said axis.
  • biasing means comprises a pair of hydraulic cylinder and piston units.
  • each of said block-and-tackle means comprises a warping block at the respective second end portion; and wherein each of said warping blocks is articulately connected with the respective first arm.
