Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft eine Schraube, deren Flügel mittels an ihre Drehzapfen angelenkter Kurbeln durch die verschiebbare Schraubenwelle verstellt werden können. Die Erfindung besteht darin, daß die Kurbeln zum Drehen der Flügel an den durch die Nabe hindurchragenden freien Enden der Flügelzapfen angreifen, und daß an die Kurbeln Lenker angeschlossen sind, die mit einem gleichachsig ίο zur Schraubenwelle gerichteten, am Rudersteven drehbar, aber unverschieblich gelagerten Wellenstumpf verbunden sind.The invention relates to a screw, the wings of which are hinged to their pivot pins Cranks can be adjusted by the sliding screw shaft. The invention consists in the fact that the cranks for rotating the blades on the protruding through the hub Attack free ends of the wing pin, and that the handlebars are connected to the cranks are on the rudder stem with a coaxial ίο directed to the propeller shaft rotatably but immovably mounted shaft stub are connected.

Die Schraubenwelle α ist in dem Schraubensteven b verschieblich gelagert und kann mit Hilfe des im Schiffskörper abgestützten Stellhebeis c in bestimmten Grenzen hin und her bewegt werden. Sie trägt am äußeren Ende die Schraube, deren Flügel d an der Nabe e drehbar angeordnet sind.The screw shaft α is displaceably mounted in the screw stem b and can be moved to and fro within certain limits with the aid of the adjusting lever c supported in the hull. At the outer end it carries the screw, the wings of which are rotatably arranged on the hub e.

Die freien Enden der Schraubenflügelzapfen ragen durch die Nabe β hindurch, in welcher sie durch Gegenmuttern oder in anderer WeiseThe free ends of the screw wing pins protrude through the hub β , in which they are secured by lock nuts or in some other way

gesichert werden. An den freien Enden der Flügelzapfen greifen Kurbelarme g an, die durch Lenker h an einen gleichachsig zur Schraubenwelle α gerichteten, am Rudersteven i drehbar, aber unverschieblich gelagerten Wellenstumpf k angeschlossen sind. Das durch die Kurbeln g gebotene Übersetzungsverhältnis wird dabei so gewählt, daß bei der Verschiebung der Schraubenwelle a aus der einen in die andere Endstellung die Schraubenflügel von Rückwärts- auf Vorwärtsgang oder umgekehrt umgestellt werden.secured. Crank arms g engage at the free ends of the wing pegs and are connected by link h to a stub shaft k which is oriented coaxially to the screw shaft α and rotatably but immovably mounted on the rudder stem i. The transmission ratio offered by the cranks g is selected so that when the screw shaft a is shifted from one end position to the other, the screw blades are switched from reverse to forward gear or vice versa.
