Abstract

Said system includes two lateral hulls (B), of which there can be two, three, four or more. Said hulls have various shapes and dimensions. Mounted on any system, they are capable of rotating about the central vessel (I), from port side to starboard side and vice versa.

Description

Le système se compose de coques latérales B qui peuvent être au nombre de deux, trois, quatre ou plus; ces coques sont de formes et de dimensions diverses. Elles peuvent, avec n'importe quel système, tourner autour de l'embarcation centrale I.The system consists of side hulls B which can be two, three, four or more; these hulls are of various shapes and sizes. They can, with any system, turn around the central boat I.

De bâbord à tribord et vice versa. Lorsque les coques sont immergées, elles appliquent une poussée verticale constante qui soutient l'embarcation.From port to starboard and vice versa. When the hulls are submerged, they apply a constant vertical thrust that supports the boat.

DISPOSITIF A DEUX COQUES LATERALES DOUBLES (dessins 1 - 4)DEVICE HAVING TWO LATERAL DOUBLE SHELLS (Drawings 1-4)

Si la mer devait entraîner un chavirement, situation qui est peu envisageable en raison de la double poussée, une des coques passerait alors sous la quille et l'autre se retrouverait en hauteur, à côté du pont et en surplomb; cependant, un des deux bras C, en tournant, enclencherait l'extension du piston "G" (poupe et proue) et de surcroît, le bras en surplomb, en tombant, passerait devant un autre mécanisme qui lui fera retourner les pistons G dans leur position initiale. L = L1 (action).If the sea were to cause a capsize, a situation that is unlikely because of the double thrust, one of the hulls would then go under the keel and the other would be up, next to the bridge and overhanging; however, one of the two arms C, turning, would engage the extension of the piston "G" (stern and bow) and in addition, the overhanging arm, falling, would pass in front of another mechanism that will make him turn the pistons G in their initial position. L = L1 (action).

Le dispositif sera pourvu d'un arrêt de course réglable.The device will be provided with an adjustable stroke stop.

La manoeuvre durera 10 à 15 secondes, moment durant lequel il y aura une instabilité.The maneuver will last 10 to 15 seconds, during which time there will be instability.

Dans le dispositif à deux et trois coques, on a prévu un mécanisme qui sera logé à l'intérieur de l'essieu et qui empêchera aux deux tuyaux de l'huile de s'entortiller.In the two and three-hull device, there is a mechanism which will be housed inside the axle and which will prevent the two pipes of the oil from kinking.

Une pompe à huile, ACTIONNEE manuellement, sera installée dans le circuit au cas où la pompe à moteur ne fonctionnerait pas.An oil pump, ACTUATED manually, will be installed in the circuit in case the motor pump does not work.

DISPOSITIF A TROIS COQUES DOUBLES: trois bras et trois pistons G1-G2-G3 satisfont L0 - L1, de plus, D satisfait K.DEVICE WITH THREE DOUBLE SHELLS: three arms and three pistons G1-G2-G3 satisfy L0 - L1, moreover, D satisfies K.

Sur le dessin 7, on peut voir le dispositif en L qui a subit un renversement.In the drawing 7, one can see the L-shaped device which has undergone a reversal.

Le piston G1 qui se trouvait en bas est passé à tribord alors que le piston G2, qui était à bâbord, est passé en bas; pour remettre le mécanisme en L, il faudra allonger G2 et simultanément, G1 se raccourcira. Le piston G3 reste immobile. La manoeuvre s'effectuera toujours entre le piston qui se trouvera en bas et celui qui s'y trouvait précédemment.The piston G1 which was at the bottom went to starboard while the piston G2, which was on the port side, passed down; to put the mechanism in L, it will lengthen G2 and simultaneously, G1 will shorten. The piston G3 remains motionless. The maneuver will always take place between the piston which will be at the bottom and the one which was there previously.

Si la mer redevient calme (cfr DES. 8), on peut mettre le dispositif en position L0 en allongeant le piston G2 et en raccourcissant G1 - G3.If the sea becomes calm again (see section 8), the device can be put in position L0 by lengthening piston G2 and shortening G1 - G3.

Pendant ce temps, l'huile des pistons G1 - G3 passera dans le piston G2 qui s'allongera.Meanwhile, the pistons oil G1 - G3 will pass into the piston G2 which will lengthen.

Sur le DESSIN 12, on peut voir une embarcation chargée vue de l'arrière.On DRAWING 12, you can see a loaded boat seen from behind.

DISPOSITIF COMPOSE DE QUATRE COQUES et quatre bras, est en position L (Action), les bras D satisfont K et peuvent être prolongés grâce à quatre pistons hydrauliques ou grâce à quatre crics à crémaillère. L'ouverture des bras à compas peut être effectuée avec n'importe quel système ou, comme sur le dessin, le piston G satisfait L0 - L1.COMPRISING FOUR HULL and four arms, is in the L (Action) position, the arms D satisfy K and can be extended by means of four hydraulic pistons or four rack-and-pinion jacks. The opening of the compass arms can be performed with any system or, as in the drawing, the piston G satisfies L0 - L1.

Les deux pistons Z servent à distancer de façon symétrique les deux coques en hauteur; le distanciateur "M", en hauteur, glissera à l'intérieur de son logement. Lorsque le dispositif est placé dans la position désirée, il faut fermer les robinets de l'huile, arrêter la pompe et détacher les tuyaux reliés au mécanisme. Dans cette position, il pourra tourner à volonté et sans aucun problème.The two pistons Z serve to symmetrically distance the two hulls in height; the distancer "M", in height, will slide inside its housing. When the device is placed in the desired position, the oil valves must be closed, the pump stopped and the pipes connected to the mechanism are disconnected. In this position, he can turn at will and without any problem.

La forme des coques latérales peut varier par rapport à celle qui est représentée sur les DES. 10 - 13.The shape of the lateral hulls may vary from that shown on the DES. 10 - 13.

DISPOSITIF VU SUR LES DESSINS 14 - 19, il se compose de quatre coques latérales. La forme des coques peut être modifiée.DEVICE SEEN ON DRAWINGS 14-19, it consists of four lateral hulls. The shape of the hulls can be modified.

Il s'agit d'un système simple formé de quatre bras C qui servent de logement aux quatre bras "D", ils peuvent s'allonger par l'intermédiaire des pistons hydrauliques ou de tout autre genre de dispositif, ils peuvent satisfaire "K" de plus, le système est pourvu de quatre tubes "W" qui servent de logement aux bras verticaux "V" qui, eux, satisfont L0 - L1 (cfr DES. 16).It is a simple system consisting of four arms C which serve as housing for the four arms "D", they can extend by means of the hydraulic pistons or any other kind of device, they can satisfy "K "In addition, the system is provided with four tubes" W "which serve as housing for the vertical arms" V "which themselves satisfy L0 - L1 (see DES 16).

Les bras verticaux "V" peuvent être allongés via un système identique à celui des bras "D".The vertical arms "V" can be extended via a system identical to that of the arms "D".

Ce dispositif peut, comme on le remarque si on se réfère au DES. 16, s'adapter aux petites et aux grandes embarcations. Les coques en pointillés représentent le dispositif dans la position L0. Quand le mécanisme est placé dans la position souhaitée, il faut fermer les robinets de l'huile, arrêter la pompe et détacher les tuyaux reliés au système.This device can, as noted if we refer to DES. 16, adapt to small and large boats. The dotted shells represent the device in the L0 position. When the mechanism is in the desired position, the oil valves must be closed, the pump stopped, and the pipes connected to the system disconnected.

Dans cette position, il peut tourner chaque fois que la mer tentera de faire chavirer l'embarcation.In this position, he can turn whenever the sea tries to capsize the boat.
