Zusatz-Patent zu No. 21501 vom 22. Juli 1882.Patent addition to No. 21501 of July 22, 1882.
Patentirt im Deutschen Reiche vom 29. Januar 1884 ab. Längste Dauer: 21. Juli 1897.Patented in the German Empire on January 29, 1884. Longest duration: July 21, 1897.
Die vorliegende Einrichtung bezweckt, die im Haupt-Patent No. 21501 angegebene Kettenanordnimg dahin zu verbessern, dafs sich beim Aufrollen die Seitenketten b selbstthätig so reguliren, dafs deren Radien gleich sind mit den Radien der Innenketten c, wobei zugleich die Lage der Drehpunkte, sowie der Stabquerschnitt innerhalb gewisser Grenzen beliebig gewählt sein kann.The present device aims at that in main patent no. 21501 to improve the chain arrangement given so that when rolling up the side chains b automatically regulate themselves so that their radii are equal to the radii of the inner chains c, whereby at the same time the position of the pivot points as well as the rod cross-section can be chosen arbitrarily within certain limits.
Zu diesem Zweck sind die Seitenketten b nicht direct, sondern durch die Excenter e mit den Zapfen F der Stäbe a in Verbindung. Die am oberen Kettenende befindlichen Haken h hängen sich beim Herablassen, Fig. 1, in entsprechende Ausschnitte der Laufhuthen g ein und bewirken bei weiterem Nachlassen der mit der Rollachse verbundenen Innenketten c die gleichzeitige Verdrehung sämmtlicher Stäbe. Beim Aufziehen, Fig. 2, schliefsen sich zunächst die Stäbe, ferner sinken die Seitenketten b unter Verdrehung der Excenter e relativ so weit herab, als es die Schlitze in den Haken h gestatten. Hierdurch bildet sich in diesen nun lose hängenden Ketten eine Reserve, die, wenn beim Aufwickeln Radiendifferenz obwaltet, angezogen wird.For this purpose, the side chains b are not directly, but are connected to the pegs F of the rods a through the eccentrics e . The hooks h located at the upper end of the chain hang when lowering, FIG. 1, into corresponding sections of the running hats g and, if the inner chains c connected to the roller axis continue to slacken, cause the simultaneous rotation of all rods. When pulling up, FIG. 2, the bars initially close, furthermore the side chains b sink, with the rotation of the eccentrics e, relatively as far down as the slots in the hooks h allow. This creates a reserve in these loosely hanging chains, which is tightened if there is a difference in radius during winding.
Da nun aber mit diesem Anziehen die Excenter e sich zu Gunsten der Radienverkleinerung dieser Seitenketten b bewegen, so wird der Gleichheitszustand der Radien beider Ketten b und c selbstthätig herbeigeführt und dadurch eine zwanglose Aufwickelung überhaupt ermöglicht. But since with this tightening the eccentrics e move in favor of the reduction in the radius of these side chains b , the equality of the radii of both chains b and c is automatically brought about and thus an unconstrained winding is made possible at all.
