Rollenblock Patentiert im Deutschen Reiche vom 19. Mai 1931 abRoller block Patented in the German Empire on May 19, 1931

Seilflaschenzüge müssen häufig wegen der beschränkten Raumverhältnisse so schmal wie möglich, gehalten werden. Dabei ist man in der Breite an die zulässige Flächenpressung zwischen der Rolle und dem Bolzen gebunden. Man hat auch, schon die Rollen in vertikaler Richtung gegeneinander versetzt. Beim Gegenstand der Erfindung laufen die Seilrollen α mit ihren Naben & in oder auf ίο den Naben der Nachbarrollen. Die Außennaben der äußeren Rollen sind in den Tragschilden d gelagert. Hierdurch, wird erreicht, daß bei der Summe der Einzelmaße für die Breite der Flasche die Naben ganz fortfallen und die Breite der Flasche sich, nur zusammensetzt aus der Summe der Kränze der Seilrollen und Tragschilde nebst etwas Spiel zwischen denselben. Zur Verringerung der Reibung sind Gleit- oder Rollenlager c vorgesehen, aoRope pulley blocks often have to be kept as narrow as possible due to the limited space available. The width is bound to the permissible surface pressure between the roller and the bolt. The rollers have also been offset against each other in the vertical direction. In the subject matter of the invention, the rope pulleys α run with their hubs & in or on ίο the hubs of the neighboring pulleys. The outer hubs of the outer rollers are mounted in the support plates d. In this way, it is achieved that in the sum of the individual dimensions for the width of the bottle, the hubs are completely omitted and the width of the bottle is only composed of the sum of the wreaths of the pulleys and support plates plus some play between them. To reduce friction, slide or roller bearings c are provided, ao
