H. WIECHERT in BERLIN. Verfahren zur Herstellung von Schmirgelscheiben.H. WIECHERT in BERLIN. Process for the production of emery discs.

Patentirt im Deutschen Reiche vom 24. Mai 1878 ab.Patented in the German Empire on May 24, 1878.

Die Herstellungsmethode ist folgende:The manufacturing method is as follows:

Ein Quantum feines oder grobes Schmirgelpulver wird 'mit einer Quantität Glasur bezw. einem Glassatz gemischt und durch Zusatz von Thon und Wasser als Bindemittel in eine teigartige Masse verwandelt. Diese Masse bringt man durch Druck in eine bestimmte Form, also in die einer Scheibe.A quantity of fine or coarse emery powder is' with a quantity of glaze respectively. mixed with a set of glass and made into a doughy one by adding clay and water as binders Transformed mass. This mass is brought into a certain shape by pressure, i.e. into that of a disk.

Nachdem so die Masse Form erhalten, setzt man dieselbe der Schmelzhitze aus.After the mass has obtained its shape, it is exposed to the heat of the melt.

Man erzielt auf diese Weise eine sehr innige Verbindung des Korns, gleichzeitig eine erforderliche Porosität des Formstückes, welches bei seiner grofsen Härte selbst von der feinsten englischen Feile so gut wie nicht angegriffen wird, sich vorzüglich zum Schleifen oder Poliren von gehärteten Stahlgegenständen eignet.In this way a very intimate connection of the grain is achieved, at the same time a necessary one Porosity of the shaped piece, which, with its great hardness, is even of the finest English file is as good as not attacked, excellent for grinding or polishing of hardened steel objects.

Die die Schmirgelscheibe einfassenden beiden Lederscheiben, sowie die Bleibüchse dienen nur zur sicheren Befestigung der Schleifscheibe auf der rotirenden Welle.The two leather disks surrounding the emery disk and the lead sleeve are used only for secure fastening of the grinding wheel on the rotating shaft.
