Description
Zum Eintreiben bestimmter Lagerstein, insbesondere für Uhren. Den Gegenstand der Erfindung bi1- det ein zum Eintreiben bestimmter Lager stein, insbesondere für Uhren. Das Eigen- ,irtige der Erfindung besteht darin, dass der Lagerstein an seiner Mantelfläche glatt pos l-lert ist.
Ein Lochstein, beispielsweise aus Granat, welcher als Lagerstein in einer Uhr oder ir_ einem andern Messinstrument, zum Beispiel einem Volt- oder Amperemeter, zur Lage rung eines Achszapfens dient und zum Ein treiben (emboutir) in seine Fassung bestimmt ist, wird an seiner Mantelfläche glatt po liert.
Es hat sich erwiesen, dass infolge der polierten Mantelfläche, die keinerlei raube Angriffspunkte für die Bohrung der Fas sung bieten, selbst bei verhältnismässig wei chen Steinen beim Eintreiben in die Fas sung keine Bruchgefahr für den Stein be- steht, beziehungsweise diese Bruchgefahr auf ein Minimum reduziert ist, während bis her weiche Steine mit rauher Mantelfläche einen verhältnismässig grossen Prozentsatz Brüche ergeben, wodurch die ganzen Steine jeweils unbrauchbar werden.
Natürlich lässt sich die Erfindung auch bei harten Steinen, Rubis, Achat usw., an wenden.
For driving certain bearing stones, especially for watches. The subject matter of the invention is a bearing block intended for driving, in particular for watches. The peculiarity of the invention is that the bearing block is smoothly pos lerted on its outer surface.
A perforated stone, for example made of garnet, which is used as a bearing stone in a watch or some other measuring instrument, for example a volt or ammeter, is used to store an axle journal and is intended to be driven (emboutir) into its socket polished smooth.
It has been shown that, due to the polished outer surface, which do not offer any rough points of attack for the bore of the mount, there is no risk of breakage for the stone when driving into the mount even with relatively soft stones, or this risk of breakage to a minimum is reduced, while previously soft stones with a rough outer surface result in a relatively large percentage of fractures, whereby the whole stones are each unusable.
Of course, the invention can also be used with hard stones, rubies, agate, etc.
