KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Der Gegenstand der Erfindung ist eine Maschine, die zum Schleifen von solchen Steinoder Kunststeinfiächen dient, die sich infolge ihrer Gröfse oder aus einer anderen Ursache zur Bearbeitung durch bisher bekannte Schleifmaschinen nicht eignen.The object of the invention is a machine that is used for grinding such stone or Artificial stone surfaces, which arise as a result of their size or for some other cause not suitable for processing by previously known grinding machines.
Fig. ι zeigt eine Ansicht, Fig. 2 einen Querschnitt der Maschine. Fig. 3 stellt einen anderen Antrieb dar.Fig. Ι shows a view, Fig. 2 shows a cross section the machine. Fig. 3 shows another drive.
Die Maschine besteht im Wesentlichen aus der senkrechten Welle 6, welche in dem Säulengesten α gelagert ist. Das Gestell ist an seinem oberen Ende in die Armstütze m ausgebogen, während das untere Ende von vier Füfsen c gebildet wird, welche durch den Ring d verbunden sind. Dieser Ring d ist an seiner Auflagefläche mit Kautschuk e belegt. Die Welle b wird durch ein konisches Räderpaar f in Umdrehung versetzt, wodurch die mit ihr durch das Kreuzgelenk g verbundene Schleif- und Polirscheibe h sich mitdreht. Durch den Hebel i und Schnurzug ο kann die Welle b sammt Schleifscheibe jederzeit von der zu bearbeitenden Fläche abgehoben werden. Dies wird dadurch ermöglicht, dafs sich die Welle mit festsitzendem Federkeile in einer Nuth des kleinen konischen Rades verschieben läfst, wobei die Knaggen / I das Rad in seiner Höhenstellung festhalten. Bei der Arbeit ruht der linke Arm in der Stütze m, während die rechte Hand die Kurbel η dreht. Die linke Hand hält hierbei die am Hebel i befestigte Schnur 0, um sobald als nothwendig die Scheibe heben zu können. Der Kautschukbelag e auf der Auflagefläche des Ringes d hat den Zweck, beim Weiterschieben der Maschine auf der zu bearbeitenden Fläche das Schleifmittel zusammenzuhalten und mit fortzuschieben.The machine essentially consists of the vertical shaft 6, which is mounted in the columnar gesture α. The frame is bent out at its upper end into the armrest m , while the lower end is formed by four feet c , which are connected by the ring d . This ring d is covered with rubber e on its contact surface. The shaft b is set in rotation by a conical pair of wheels f , as a result of which the grinding and polishing wheel h connected to it by the universal joint g rotates with it. The shaft b together with the grinding wheel can be lifted off the surface to be processed at any time by means of the lever i and the pull cord ο. This is made possible by the fact that the shaft can be displaced with firmly seated spring wedges in a groove of the small conical wheel, the lugs / I holding the wheel in its height position. During work, the left arm rests in the support m, while the right hand turns the crank η. The left hand holds the cord 0 attached to the lever i so that the disk can be lifted as soon as necessary. The purpose of the rubber covering e on the contact surface of the ring d is to hold the abrasive together and to push it away when the machine is pushed further on the surface to be processed.
Die abweichende Ausführungsform des Antriebs ermöglicht es, bei schwer zu schleifenden Flächen das konische Räderpaar s t beim Vorschleifen, und durch Umstecken des Antriebschwungrades das Räderpaar r r1 beim Nachschleifen zu verwenden.The different embodiment of the drive makes it possible to use the conical pair of wheels st for rough grinding on surfaces that are difficult to grind, and the pair of wheels rr 1 for regrinding by repositioning the drive flywheel.
