Patentirt im Deutschen Reiche vom 9. März 1899 ab.Patented in the German Empire on March 9, 1899.
Durch die amerikanische Patentschrift 542414 sind hohle Bremsschuhe bekannt geworden, die durch Ausgiefsen mit einer aus Sägemehl, Eisenfeilspänen, Graphit, Asbest und Harz bestehenden Masse die massiven Bremsklötze ersetzen sollen. Diese Bremsschuhe dürften sich jedoch in der Praxis bald als unbrauchbar erweisen, da es nicht ausgeschlossen erscheint, dafs der Säuregehalt des Harzes durch Bildung von harzsaurem Eisen eine zerstörende Wirkung auf die Masse ausübt.The American patent 542414 made hollow brake shoes known which by pouring with one of sawdust, iron filings, graphite, asbestos and resin existing mass to replace the massive brake pads. These brake shoes should but soon prove to be unusable in practice, as it does not appear to be ruled out that the acidity of the resin has a destructive effect through the formation of resinous iron exercises on the crowd.
Des Weiteren ergiebt eine Mischung von Graphit, Asbest, Eisenfeilspänen, Sägemehl und Harz eine nur mäfsig harte Masse, welche daher als Bremsmasse nicht sehr geeignet er-, scheint.A mixture of graphite, asbestos, iron filings and sawdust also results and resin is only a moderately hard compound, which is therefore not very suitable as a braking compound, appears.
Die vorliegende, in dem unten beschriebenen Verfahren näher gekennzeichnete Masse zum Ausgiefsen von hohlen Bremsklötzen beseitigt diese Mifsstände vollständig, da die zur Mischung kommenden Bestandtheile so gewählt sind, dafs einerseits keine frühzeitige Zerstörung in der Masse selbst entstehen kann, andererseits eine äufserst feste und harte Masse gebildet wird.The present, in the method described below in more detail for the The filling of hollow brake blocks completely eliminates this problem, since the Mixing components are chosen so that on the one hand no premature destruction can arise in the mass itself, on the other hand an extremely solid and hard mass is formed.
Diese Masse besteht aus Schwefel, Graphit, Flufssand und Filterkies und wird nach folgendem Verfahren hergestellt:This mass consists of sulfur, graphite, river sand and filter gravel and is made according to the following Process made:
Man läfst zunächst 10 Theile Schwefel so lange kochen, bis der Schwefel dünnflüssig wird. Hierauf werden diesem Schwefel 4 Theile pulverisirten Graphits zugesetzt, dann 4 Theile Filterkies und 5 Theile Flufssand. Nachdem die Masse unter tüchtigem Rühren aufgekocht hat, wird sie in entsprechende Formen oder direct in die hohlen Bremsschuhe eingegossen. Nach dem Erkalten ist die Masse gebrauchsfertig und kann sofort verwendet werden.At first 10 parts of sulfur are allowed to run for that long cook until the sulfur becomes thin. Four parts of this sulfur are then pulverized Graphite added, then 4 parts filter gravel and 5 parts river sand. After the crowd has boiled with thorough stirring, it is in appropriate forms or directly in the hollow brake shoes cast in. After cooling, the mass is ready to use and can can be used immediately.
