PATENTAMT.PATENT OFFICE.
Den Gegenstand der vorliegenden Erfindung bildet ein Schaufelkettentreiber für Schiffe, welcher sich von den bekannten dadurch unterscheidet, dafs die Querschnitte der Schaufeln rechtwinklig gleichschenklige Dreiecke sind, wobei die Drehachse der Schaufeln an der rechtwinkligen Kante angebracht ist. Die Erfindung ist auf der beiliegenden Zeichnung dargestellt und zeigtThe subject of the present invention is a bucket chain driver for ships, which differs from the known ones in that the cross-sections of the blades are right-angled isosceles triangles, with the axis of rotation of the blades at the right-angled edge is attached. The invention is on the accompanying drawing illustrated and shows
Fig. ι einen Längsschnitt durch den Schaufeltreiber, Fig. Ι a longitudinal section through the blade driver,
Fig. 2 einen Theil der im Wasser gehenden Schaufeln von oben gesehen',Fig. 2 shows a part of the blades going in the water seen from above,
Fig. 3 einen Querschnitt hierzu.Fig. 3 shows a cross section of this.
Die Schaufelketten α laufen über zwei Paare Zahnräder b, von denen das eine Paar von der Maschine des Schiffes seine Drehung erhält. Die Ketten selbst sind durch Stangen c mit einander verbunden, an denen \3ie Schaufeln e drehbar befestigt sind; die Stangen tragen an den Enden Rollen d. Vor und hinter den Stangen c ist noch je eine Stange/g- angebracht, welche gleichfalls die Ketten verbinden und mit Rollen an ihren Enden versehen sind. Die Schaufeln e haben im Querschnitt die Form eines rechtwinklig gleichschenkligen Dreiecks und legen sich stets mit einer ihrer Kathetenflächen an die Ketten α; sie sind um die Stangen c mit ihrer rechtwinkligen Kante drehbar.The shovel chains α run over two pairs of toothed wheels b, one pair of which receives its rotation from the ship's engine. The chains themselves are connected to one another by rods c to which the blades e are rotatably attached; the rods have rollers at the ends d. A rod / g- is attached in front of and behind the rods c , which also connect the chains and are provided with rollers at their ends. The blades e have the shape of a right-angled isosceles triangle in cross section and always lie with one of their cathetus surfaces on the chains α; they are rotatable around the rods c with their right-angled edge.
An den Schiffswänden sind in der Höhe der Kettenbahnen horizontale Führungen für die Gleitrollen der Stangen angebracht, und zwar an der unteren Bahn der Ketten zwei, h und i, an der oberen Bahn eine Führung k\ auf diesen bezw. zwischen diesen Führungen laufen die Rollen der Stangen efg. Diese Führungen dienen dazu, ein Durchbiegen der Ketten nach oben oder unten zu verhindern.Horizontal guides for the sliding rollers of the rods are attached to the ship's walls at the level of the chain tracks, on the lower track of the chains two, h and i, on the upper track a guide k \ on these respectively. between these guides run the roles of the rods efg. These guides are used to prevent the chains from bending up or down.
Durch die Form und Befestigungsart der Schaufeln wird bewirkt, dafs einerseits infolge der lose hängenden Schaufeln jeder Schlag auf das Wasser beim Eintauchen derselben vermieden wird, andererseits das Rückwärtsfahren des Schiffes dadurch in einfachster Weise ermöglicht wird, dafs die Schaufelnvinfolge des Wasserdruckes ihre Stellung ändern und sich mit den anderen Kathetenflächen, die vorher gegen die Ketten drückten, nun senkrecht zur Bewegungsrichtung stellen.By the shape and fastening of the blades is effected, that on the one hand the same is avoided due to the loosely hanging blades each beat of the water during immersion, on the other hand, the reversing of the vessel is made possible in einfachster way, that the vanes v due to the water pressure their position change and now position yourself perpendicular to the direction of movement with the other cathetus surfaces that previously pressed against the chains.
Diese Schaufelkettentreiber können sowohl in einem mittschiffs liegenden Kanal als auch zu beiden Seiten des Schiffes angebracht sein.These shovel chain drivers can be used in a midships channel as well be attached on both sides of the ship.
Claims (1)
Ein Schaufelkettentreiber, gekennzeichnet durch prismatische Schaufeln, deren Querschnitt die Form eines rechtwinkligen, gleichschenkligen Dreiecks hat, und welche um die rechtwinklige Kante drehbar an in Führungen laufenden Achsen sitzen, die an den betreffenden Stellen die Bolzen der Ketten ersetzen, während vor und hinter diesen Achsen je eine zweite, ebenfalls geführte Achse angeordnet ist, welche den Druck, den die horizontale Fläche der Schaufeln auf die Kette ausübt, aufnimmt.Patent claim:
A shovel chain driver, characterized by prismatic shovels, the cross-section of which has the shape of a right-angled, isosceles triangle, and which are rotatably mounted around the right-angled edge on axes running in guides, which replace the bolts of the chains at the relevant points, while in front of and behind these axes a second, also guided axle is arranged, which absorbs the pressure exerted by the horizontal surface of the blades on the chain.
