Patentiert im Deutschen Reiche vom io. März 1938 ab Patenterteilung bekanntgemacht am 14. Dezember 1939Patented in the German Empire by the io. March 1938 Patent issued December 14, 1939
Gemäß § 2 Abs. 2 der Verordnung vom 28. April 1938 ist die Erklärung abgegeben worden, daß sich der Schutz auf das Land Österreich erstrecken sollAccording to Section 2 (2) of the Ordinance of April 28, 1938, the declaration has been made, that protection should extend to the country of Austria
Für die Unterteilung eines Kreises sind neben mit optischer Einstelleinrichtung versehenen Geräten sowie den gewöhnlichen Loch- oder Nutscheiben Teilvorrichtungen bekannt, die mit mehreren hintereinandergeschalteten Schneckengetrieben die Feineinstellung herbeizuführen suchen, sowie auch Kreisteilvorrichtungen mit einem Stirnrad und einem damit kuppelbaren Einführungsteil für die Grobeinstellung, insbesondere Gradeinteilung sowie mit einer Mikrometerschraube tür die Feineinstellung.For the subdivision of a circle there are also provided with optical adjustment devices Devices as well as the usual perforated or grooved disks sub-devices known, the fine adjustment with several worm gears connected in series seek to bring about, as well as circular dividing devices with a spur gear and an introductory part for coupling with it the coarse adjustment, especially graduation and with a micrometer screw for fine adjustment.
Bei den optischen Teilköpfen ist der Feineinstellung eine verhältnismäßig hochliegende Grenze gesetzt, die kaum unter 1J4 Bogenminute heruntergeht. Die Kreisteilvorrichtungen mit Schneckengetrieben unterliegen einer verhältnismäßig großen Abnutzung und leiden außerdem darunter, daß Schneckenräder nicht mit genügender Genauigkeit herstellbar sind; sie können nur gefräst, nicht aber geschliffen werden.With the optical dividing heads, the fine adjustment is set a relatively high limit, which hardly goes below 1 J 4 arc minutes. The circular dividing devices with worm gears are subject to a relatively large amount of wear and tear and also suffer from the fact that worm gears cannot be manufactured with sufficient accuracy; they can only be milled, but not ground.
Die mit einem Stirnrad und damit kuppelbarem Eingriffsteil für die Grobeinstellung arbeitenden Kreisteilvorrichtungen unterliegen diesem Nachteil nicht, weil sich das Stirnrad äußerst genau schleifen läßt. Daher geht die Erfindung < ebenfalls von einem Stirnrad und damit kuppelbarem Eingriffsteil für die Grobeinstellung aus und verwendet ebenfalls eine Mikrometerschraube für die Feineinstellung. Im Gegensatz zu den bekannten Einrichtungen vermeidet sie aber die Gefahr der Abnutzung der Feineinstellungsvorrichtung dadurch, daß diese unabhängig vom Zahnrad und dem Angriffsteil gelagert und drucklos einstellbar ist und daß das Zahnrad mit dem Eingriffsteil mittels eines von der Grob- wieThe engaging part with a spur gear and thus couplable engagement part for the coarse adjustment working circle dividing devices are not subject to this disadvantage, because the spur gear can be grinded extremely precisely. Therefore, the invention <is also based on a spur gear and thus coupling engagement part for the coarse adjustment and also uses a Micrometer screw for fine adjustment. In contrast to the well-known facilities but it avoids the risk of wear and tear on the fine adjustment device by that this is stored independently of the gear and the attack part and can be adjusted without pressure and that the gear with the Engaging part by means of one of the coarse as
