Description

KAISERLICHESIMPERIAL

PATENTAMT,PATENT OFFICE,

Nachstehend ist eine Einrichtung beschrieben und auf der beiliegenden Zeichnung dargestellt, durch welche das Abziehen des beim Scheuern von Metallgegenständen und dergl. in der Scheuertrommel entstehenden Staubes und der zum Scheuern verwendeten feinen Mittel ermöglicht wird, so daß die Staubteile aus der Trommel nicht in den Arbeitsraum gelangen und das später vorzunehmende, gesundheitsschädliche Abstäuben oder Sieben der gescheuerten Gegenstände nicht mehr nötig ist. Die Trommel α wird mit Zapfen b versehen, die an der Trommel durch Schrauben oder ' in anderer Weise befestigt werden. Zweckmäßig erhält die Trommel an der Stelle, wo die Zapfen angebracht sind, siebartige Lochungen, während die Zapfen mit einer Aushöhlung c versehen. sind, so daß ein freier Raum zwischen Trommel und AchsenHantsch entsteht. Auf einen der über das Lager hervorstehenden Zapfen wird eine Hülse d geschoben, die zum Zwecke einer besseren Dichtung über einen vorspringenden Rand des Zapfens greift. Die Hülse d wird lose am Zapfen angebracht, während sie mit ihrem anderen Ende an das Saugrohr eines Ventilators oder dergl. angeschlossen ist. Dieses Rohr wjrd mit einem Absperrventil ν versehen, so daß das Abziehen des Staubes beliebig geregelt werden kann.A device is described below and shown in the accompanying drawing, by means of which it is possible to remove the dust and the fine agents used for scrubbing from the scrubbing of metal objects and the like in the scrubbing drum, so that the dust particles from the drum do not enter the work space and the harmful dusting or sieving of the scrubbed objects, which has to be carried out later, is no longer necessary. The drum α is provided with pins b which are fastened to the drum by screws or in some other way. The drum is expediently provided with sieve-like perforations at the point where the pins are attached, while the pins are provided with a cavity c. so that there is a free space between the drum and the axle handle. A sleeve d is pushed onto one of the pins protruding from the bearing and engages over a protruding edge of the pin for the purpose of a better seal. The sleeve d is loosely attached to the pin, while its other end is connected to the suction pipe of a fan or the like. This pipe is provided with a shut-off valve ν so that the extraction of the dust can be regulated as required.

Der zum Ansaugen der Luft dienende Lagerzapfen braucht nicht hohl gestaltet zu sein, da sich siebartige Öffnungen, durch welche die Luft angesaugt wird, neben demselben in der Trommel befinden können.The bearing pin used for sucking in the air does not need to be made hollow, since sieve-like openings through which the air is sucked in next to the same in the Drum can be located.

Die Zapfen können auch in Gestalt eines Rohres, das innerhalb der Trommel mit Bohrungen versehen ist, durch dieselbe durchgeführt sein.The pins can also be in the form of a tube that is drilled inside the drum is provided, be carried out by the same.
