Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Gegenstand der "Erfindung bildet eine Vorrichtung, mittels welcher das Gleiten des Seiles oder Riemens an Bremsrollen bezw. Riemscheiben auch bei wechselnder Belastung selbsttätig verhindert wird.The "invention provides a device by means of which the sliding of the Rope or belt on brake rollers respectively. Belt pulleys even with changing loads is automatically prevented.

Fig. ι und 2 zeigen eine Bremsrolle beliebiger Anordnung. Unter der Rolle α sind zwei zwischen zwei Platten b gelagerte Rollen c angebracht, die etwas angedrückt amFig. Ι and 2 show a brake roller of any arrangement. Under the roller α two mounted between two plates b rollers c are attached, which is slightly pressed on the

ίο Seil s anliegen. Die Platten sind an den Unterkanten d nach beiden Seiten abgeschrägt und sind in ihrer Mitte auf einem Zapfen e aufgesetzt, so daß sie gleicharmige Hebel bilden.ίο rope s applied. The plates are beveled at the lower edges d on both sides and are placed in their center on a pin e so that they form levers with equal arms.

Wird auf der einen Seite an dem Seil ein Zug ausgeübt, so wird dieser sich als Druck auf den anderen Hebelarm und die Rolle übertragen, wodurch der gegenüberliegende Hebelarm mit der Rolle gegen das Seil und dieses in die Scheibenrille gedrückt wird.If a pull is exerted on the rope on one side, this will be seen as pressure transferred to the other lever arm and the roller, creating the opposite Lever arm with the roller against the rope and this is pressed into the pulley groove.

Rücken nun bei wachsender Belastung infolge des seitlichen Zuges die Platten b etwas vor, so kommen die schrägen Unterkanten d zur Wirkung, wodurch die gegenüberliegende Rolle noch stärker an das Seil gedrückt wird. If the plates b move forward slightly as the load increases as a result of the lateral pull, the inclined lower edges d come into effect, whereby the opposite roller is pressed even more strongly against the rope.

Fig. 3 und 4 zeigen eine Riemscheibe mit dieser Einrichtung, die im Wesen ganz dieselbe ist. α ist die Riemscheibe, cc sind leicht drehbare Walzen, b b die Verbindungsstücke mit den schrägen Unterkanten d d, s der Treibriemen, e ein Zapfen, welcher den örtlichen Umständen gemäß (etwa beiderseitig irn Gebälk) befestigt ist.Figures 3 and 4 show a pulley with this device which is essentially the same. α is the pulley, cc are easily rotatable rollers, bb the connecting pieces with the sloping lower edges dd, s the drive belt, e a pin, which is fastened according to the local circumstances (e.g. on both sides in the entablature).

Claims (1)

Patent-Anspruch:Patent claim: Selbsttätige Vorrichtung zur Verhinderung des Gleitens von Seilen oder Riemen auf Bremsrollen oder Riemscheiben, dadurch gekennzeichnet, daß zwei Rollen (c) zwischen gleicharmige Hebel bildenden Platten (b) gelagert sind, die, mit schrägen Unterkanten (d) versehen, wagebalkenartig auf einem Zapfen (e) lagern, so daß ein mittels eines über die Rollen laufenden Seiles (oder Riemens) ausgeübter Zug sich als Druck auf die gegenüberliegende Rolle überträgt, die das Seil (oder den Riemen) an die Scheibe drückt.Automatic device for preventing ropes or belts from sliding on brake rollers or pulleys, characterized in that two rollers (c) are mounted between plates (b) which form levers of equal arms and which, provided with sloping lower edges (d) , are mounted on a pin ( e) store so that a pull exerted by means of a rope (or belt) running over the pulleys is transmitted as pressure to the opposite pulley, which presses the rope (or belt) against the pulley.
