Title: Method of combined navigation of a barge or a lighter on sea and inland waters and apparatus for carrying out the said method
Claims: What is claimed is: 1. Method of navigation of a first barge on sea and/or on inland waters, consisting, for the purpose of, for example, allowing the said first barge to navigate on the sea, in securing on the said barge, for example on the after-deck thereof, a removable propelling plant proceeding from a second barge, wherein the improvement consists in that the said first barge and the said second barge are substantially joined together side by side, the said removable propelling plant is detached from the said second barge and is then subjected to a lateral displacement with respect to the said two barges until it reaches a predetermined position on the said first barge before being locked on the latter in the said predetermined position. 2. Method according to claim 1, wherein, before the said lateral displacement of the propelling plant, at least two movable beams previously located on the said second barge are subjected to a longitudinal displacement transversely of the latter until the said beams reach a position in which they rest by their ends upon both barges, each of the said ends resting upon one of the barges, preferably at a point located substantially in the medial longitudinal plane thereof, and then, after the said lateral displacement of the propelling plant along the said beams is continued to a position of rest on the said first barge. 3. Method according to claim 1, including the step of causing a mass of water corresponding substantially to the mass of the propelling plant to pass progressively from said first barge to said second barge simultaneously with the lateral displacement of the propelling plant from said second barge to said first barge. 4. Apparatus for the navigation of a barge on sea and/or on inland waters, comprising a removable propelling plant having means thereon for tranferring same from one barge to another barge and for anchoring same to such other barge, complementary transferring and anchoring means on the other barge cooperable with said transferring and anchoring means on said propelling plant for transfer thereof from said one barge to the other barge and for anchoring the propelling plant on the other barge, the said transferring means being constituted by several devices forming wheel-trains secured to the base of said propelling plant and by at least two beams arranged transversely of the said other barge and movable along their longitudinal axes, the complementary transferring means being constituted by several stationary rails arranged transversely of the said other barge and secured thereto, the said beams and the said rails being so arranged as to form a guiding structure upon which the said devices forming wheel-trains can bear and along which they can move. 5. Apparatus according to claim 4, wherein the said devices forming wheel-trains are secured to the said propelling plant through the medium of hydraulic cylinders. 6. Apparatus according to claim 4, wherein each movable beam is embedded, when at rest, between two said stationary rails and each device forming a wheel-train includes at least one group of three coaxial wheels, the two outermost wheels being adapted to come into rolling contact with the two stationary rails and the central wheel being adapted to come into rolling contact with the movable beam. 7. Apparatus according to claim 6, comprising a connection between the devices forming the wheel-trains and the movable beam associated with the said devices, the said connection being constituted by at least one pair of coaxial rollers mounted at the lower portion of each device forming a wheel-train, the said rollers rotating freely and being adapted to come into rolling contact with the internal faces of the two horizontal, longitudinally continuous surfaces of the said associated movable beam. 8. Apparatus according to claim 4, wherein the said wheel-trains are three in number, and in triangular arrangement, and the anchoring means and the complementary anchoring means are retractable. 9. Apparatus for the navigation of a barge on sea and/or on inland waters, comprising a removable propelling plant having means thereon for transferring same from one barge to another barge, and for anchoring same to such other barge, complementary transferring and anchoring means on the other barge cooperable with said transferring and anchoring means on said propelling plant for transfer thereof from said one barge to the other barge and for anchoring of the propelling plant on the other barge, the said transferring means being constituted by several devices forming wheel-trains, hydraulic cylinders adapted to secure said several devices forming wheel-trains to the base of said propelling plant, additional devices forming wheel-trains secured on pivotable supports and hydraulic cylinders adapted to hingedly connect said additional devices to the sides of the propelling plant, the said complementary transferring means including several stationary rails arranged transversely of the said other barge and secured thereto.
