1877.1877. E. HOPPE m BERLIN.
Tragende Schiffsschraube.E. HOPPE in BERLIN.
Load-bearing propeller. Patentirt im Deutschen Reiche vom 8. September 1877 ab.Patented in the German Empire on September 8, 1877. Die grofsen Geschwindigkeits - und Kraftverluste, welche durch den Schiffskörper bedingt, beim Manövriren der Schiffe nothwendiger Weise auftreten müssen, sind durch das auf beiliegender Zeichnung dargestellte neue System vollkommen vermieden.The great loss of speed and force caused by the hull of the ship when maneuvering ships must necessarily occur, are due to this The new system shown in the accompanying drawing was completely avoided. Der Hauptsache nach besteht das Schiff aus einem Verdeck A, welches durch vier hohle Cylinder B getragen wird. Diese Cylinder sind je zu zweien mit einander verbunden und mit stark ansteigenden Schraubengängen versehen. Ihr Volumen ist so grofs gewählt, dafs sie ca. ein Achtel ihres Durchmessers eintauchen, wodurch der Widerstand im Wasser auf das Möglichste beschränkt ist. Diese so gebildeten zwei hohlen Schiffsschrauben tragen in Lagern d ein Rahmenwerk D aus Winkeleisen, welches seinerseits das Verdeck trägt.The main thing is that the ship consists of a canopy A, which is supported by four hollow cylinders B. Two of these cylinders are connected to one another and provided with sharply rising screw threads. Their volume is chosen so large that they are immersed about an eighth of their diameter, whereby the resistance in the water is limited to the greatest possible extent. These two hollow ship's propellers thus formed carry a framework D made of angle iron in bearings d , which in turn supports the top. Der Antrieb derselben wird durch eine Dampfmaschine R bekannter Construction bewirkt, und zwar durch Reibungsräder. Das Rad r auf der Kurbelwelle der Maschine greift in zwei Gegenräder rl und diese treiben mittelst der Räder r2 die Schrauben B um.They are driven by a steam engine R of known construction, namely by friction wheels. The wheel r on the crankshaft of the machine engages in two mating wheels r l and these drive the screws B by means of the wheels r 2. Damit das Schiff sich sicherer im Wasser bewegt, sind beide Schrauben durch eine dünne Zwischenwand w oder Flosse getrennt.In order for the ship to move more safely in the water, both screws are separated by a thin partition w or fin. Der Dampfkessel G, Kohlenbehälter H, sowie die übrigen Theile der Schiffsausrüstung sind so bekannt, dafs ihre Construction hier nicht weiter erläutert wird.The steam boiler G, coal container H, and the rest of the ship's equipment are so well known that their construction will not be further explained here. Zum Ausbalanciren etwaiger Uebergewichte oder Einzellasten dient der Kasten Z, welcher mittelst einer Pumpe mehr oder weniger mit Wasser angefüllt werden kann.Box Z, which is used to balance any excess weights or individual loads, is used can be filled more or less with water by means of a pump.
