KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung betrifft eine von den bisherigen, sogen. Bau-Winden, ganz abweichend construirte Winde, bei welcher weder eine Seil- oder Kettentrommel, noch irgend welche Zahnräder und Bremse zur Anwendung kommen, und welche trotzdem mit dem geringsten Kraftaufwand zum Heben oder Senken, eventuell gleichzeitigen Heben und Senken der schwersten Lasten dienen kann, da nur Differentialkettenrä'der den ganzen Mechanismus bilden.The present invention relates to one of the previous, so-called. Construction winches, quite different constructed winch, with which neither a rope or chain drum nor a whatever gears and brakes are used, and which ones anyway the least effort to raise or lower, possibly simultaneous lifting and Lowering the heaviest loads can serve as only differential chain wheels the whole Form mechanism.
Beiliegende Zeichnung veranschaulicht eine solche Winde zum gleichzeitigen Heben und Senken von Lasten inThe accompanying drawing illustrates such a winch for simultaneous lifting and Lowering loads in
Fig. ι und 2 in Stirn- und Seitenansicht.Fig. Ι and 2 in front and side views.
Fig. 3 zeigt ein schematisches Bild derselben Winde.Fig. 3 shows a schematic picture of the same winch.
Die Winde besteht aus dem gewöhnlichen Bauwindengestell a, auf . welchem die mit Drehkurbel b versehene Welle c gelagert ist. Letztere * trägt innerhalb des Gestelles zwei festgekeilte, vollkommen gleiche Differentialkettenrä'derpaare de de, um welche eine endlose Kette/ so geführt ist, dafs zwei entgegengesetzt arbeitende Differentialflaschenzüge A und B entstehen, deren lose Schleife/1 gemeinschaftlich ist und deren Lastenschleifen je eine Lastenrolle g tragen.The winch consists of the usual construction winch frame a . which the shaft c provided with the rotary crank b is mounted. The latter * carries within the frame two tightly wedged, perfectly identical pairs of differential chain gears, around which an endless chain / is guided in such a way that two differential pulley blocks A and B work in opposite directions, whose loose loop / 1 is common and whose loops each have a load roller wear g.
Wird somit die Welle c in der Pfeilrichtung gedreht, so senkt sich die Lastenrolle g von A, während sich die andere Rolle g hebt. Dasselbe erfolgt in entgegengesetzter Weise bei umgekehrter Drehung der Welle c. Die Welle c kann auch mit einem Klinken-Sperrvorgelege h ij versehen werden, welches aber überflüssig wird, wenn die Differenz der Kettenräderdurchmesser eine entsprechend kleine ist. Zum einfachen Heben oder Senken von Lasten genügt auch eine solche Winde mit nur einem Differentialkettenradpaar de. If the shaft c is thus rotated in the direction of the arrow, the load roller g lowers from A, while the other roller g rises. The same takes place in the opposite way with reverse rotation of the shaft c. The shaft c can also be provided with a ratchet locking gear h ij , which, however, becomes superfluous if the difference in the chain wheel diameter is correspondingly small. Such a winch with just one pair of differential sprockets is sufficient for simply lifting or lowering loads .
