Zusatz zum Patente 170013 vom 23.Juni 1904.Addendum to patent 170013 of June 23, 1904.

Patentiert im Deutschen Reiche vom 11. Februar 1905 ab. Längste Dauer: 22. Juni 1919.Patented in the German Empire on February 11, 1905. Longest duration: June 22, 1919.

Die Fähreinrichtung mittels Seiles ohne Ende nach Patent 170013 kann vorteilhaft auch für solche Fähren verwendet werden, die den Fährbetrieb zwischen einem in der Nähe des Ufers ankernden Schiff und dem Lande oder zwischen zwei Schiffen vermitteln sollen. Dieser Fall liegt beispielsweise vor, wenn von einem Schiff Lasten von einem anderen Schiff oder von Land übernommen werden sollen. Ein derartiger Betrieb ist aber bei Verwendung der Einrichtung nach Patent 170013 nur dann möglich, wenn die Lage der Schiffe stets dieselbe bleibt. Ist dies nicht der Fall und werden die SchiffeThe ferry device by means of a rope without an end according to patent 170013 can be advantageous can also be used for ferries that operate ferry services between one in the Mediate the proximity of the anchored ship and the shore or between two ships should. This is the case, for example, when loads from a ship to be taken over by another ship or from shore. One such operation is but when using the device according to patent 170013 only possible if the The position of the ships always remains the same. If not and the ships will

z. B. durch den Seegang fortwährend bewegt, so ist es notwendig, daß das Fährseil, und zwar sowohl das Zug- wie das Führungsseil, in immer gleichmäßig gespanntem Zustande erhalten wird.z. B. continuously moved by the sea, it is necessary that the ferry rope, and both the pulling and the guide rope, always in an evenly tensioned condition is obtained.

Dies kann nach vorliegender Erfindung selbsttätig dadurch geschehen, daß man zum Antrieb der Spilltrommeln Motoren verwendet, deren Geschwindigkeiten von der Seilspannung verschieden beeinflußt werden. Die Einrichtung kann dabei so getroffen werden, daß die Spilltrommel T₁ von einem Motor angetrieben wird, dessen Umdrehungszahl durch irgendwelche Mittel proportional seiner Belastung geändert wird, während der Antrieb der anderen Trommel T₂ von einem Motor erfolgt, dessen Umdrehungszahl von seiner Belastung nicht oder dieser Belastung entgegengesetzt proportional beeinflußt wird. Wenn Elektromotoren verwendet werden, so kann z. B. der die Trommel T₁ antreibende Motor als Hauptstrommotor, der andere als Nebenschlußmotor gewickelt sein. Bleibt die Spannung des Seiles normal, so laufen beide Motoren und damit die Kegelräder Z₁ und Z^ mit gleicher- Umdrehungszahl. Das. Kegelrad Z^ wird sich ebenso wie die Seilrolle R nur um die eigene Achse drehen. Vergrößert sich nun der Abstand der Schiffe, so wird das Fährseil stärker gespannt, die beiden Motoren werden also höher belastet. Während nun der Motor E„ stets mit annähernd gleicher Umdrehungszahl läuft bzw. beschleunigt wird, nimmt diejenige des Motors E₁ mit wachsender Belastung ab. Durch die ungleiche Geschwindigkeit der Kegelräder Z₁ und Z₂ wird der Armhebel H mittels des Rades Z₃ so um die Achse A gedreht, daß das Fährseil gleichmäßig von beiden Trommeln abgewickelt wird. Das Seil wird also so lange verlängert, bis die Seilspannung auf das normale Maß gesunken ist, die Motoren wieder ihre normale Umdrehungszahl angenommen haben und der Armhebel H wieder stillsteht.According to the present invention, this can be done automatically by using motors to drive the capstan drums, the speeds of which are influenced differently by the rope tension. The device can be made so that the capstan drum T _{1 is driven} by a motor whose number of revolutions is changed by any means proportionally to its load, while the drive of the other drum T ₂ is done by a motor whose number of revolutions does not depend on its load or this load is influenced proportionally in the opposite direction. If electric motors are used, z. B. the motor driving the drum T ₁ as a main current motor, the other wound as a shunt motor. If the tension of the rope remains normal, both motors and thus the bevel gears Z ₁ and Z ^ run at the same number of revolutions. That. Like the pulley R, bevel gear Z ^ will only turn around its own axis. If the distance between the ships increases, the ferry rope is more taut, so the two motors are subjected to higher loads. While the motor E " now always runs or is accelerated at approximately the same number of revolutions, that of the motor E ₁ decreases as the load increases. Due to the unequal speed of the bevel gears Z ₁ and Z ₂ , the arm lever H is rotated around the axis A by means of the wheel Z _{3 in} such a way that the ferry cable is unwound evenly from both drums. The rope is lengthened until the rope tension has fallen to the normal level, the motors have returned to their normal number of revolutions and the arm lever H comes to a standstill again.

Wird der Abstand der beiden Schiffe geringer, so spielt sich der Vorgang in umgekehrter Weise ab. Die geringere Seilspannung hat zur Folge, daß der Motor E₁ schneller läuft als der Motor E₂, so daß alsoIf the distance between the two ships becomes smaller, the process is reversed. The lower rope tension has the consequence that the motor E ₁ runs faster than the motor E ₂ , so that

Claims

the rope is wound up more quickly and unwound at a steady or slower speed until normal is reached again. The facility can even be designed as a pure cable car, by means of which the loads are transported above the water level. The drums always only need to be rotated in one direction, so that, for example, the ferry rope is wound onto the drum T1 and only unwound from the drum T2. With non-locking gears, if the support points of the endless rope are at the same height, the ships maintain a constant distance and the load on the rope is uniform over the entire length, only as much energy is used as to cover the efficiency of the machine is required. Only when the rope has to be wound up when the ships come together does a greater expenditure of energy become necessary. The operation of such a ferry or cable car is completely independent of whether one ship is being towed by the other, i.e. the loads are transported during the journey, or whether the two ships are anchored. The in. The operating mapchine described in the main patent and shown there in FIG ) only one capstan drum T1 is firmly connected to the wheels S1 and Z1, while the other capstan drum T2 is loosely placed on a socket Q. on which the wheels S2 and Z2 are wedged. An advantage of this arrangement is that it avoids undue stresses on the ferry cable. When setting up the operating machine according to the main patent, in the event that the rope unwinding from one drum is always wound onto the point of the other drum at the same speed, the rope will always be evenly tensioned. However, this prerequisite will not always apply, since despite the same angular speed of the bevel gears Z and the drums T, the peripheral speed is different at the different points of the capstan drums. Thus, depending on the direction of movement, the rope will either be too slack or too tight. However, because the capstan drum T2 is loosely arranged on the socket Q., it is able to give way immediately and easily when the tension fluctuates in the rope. Godfather NT-A ν Proverbs:
