Description
Den Gegenstand der Erfindung bildet eine Einrichtung an Meßgeräten, insbesondere an 'r Rachenfehren, Flach- und Rundkalibern u.dgl. zur Aufnahme der jeweiligen Prüfungsvermerke. Die täglich im Gebrauch befindlichen Meßgeräte müssen, wenn sie ihren Zweck erfüllen sollen, regelmäßig durch Gegenlehren J nachgeprüft werden, und es ist fabrikationstechnisch von größtem wirtschaftlichen Vorteil zu wissen, wann und durch wen diese Nachprüfung geschehen ist. Das Anbringen dieser Vermerke auf d.en Meßgeräten wird dadurch erschwert, daß die Lehren glashart sind, irgendwelche Einschläge also auf ihnen nicht gemacht werden können. Die ein:?ige Möglichkeit, die Prüfungsvermerke auf den Meßgeräten anzubringen, bietet das Einätzen der Daten. Dieses Verfahren hat aber den Nachteil, daß die Meßgeräte mit diesen Vermerken schnell bedeckt werden und die auf ihnen angebrachte Toleranzmässe unübersichtlich wird. Diesem Übelstande ist nun durch die Erfindung auf die einfachste Art abgeholfen. Die Zeichnung zeigt die neue Einrichtung in Fig. 1 und 2 bei einer Rachenlehre, und in Fig. 3 und 4 bei einem Kaliberdorn. The subject invention provides a means of measuring instruments, in particular to 'r throat Fehren, flat and round calibers and the like. For receiving the respective audit certificates. The measuring devices in daily use must, if they are to fulfill their purpose, be checked regularly by counter gauges J, and it is of the greatest economic advantage in terms of manufacturing technology to know when and by whom this check has been carried out. The application of these notes on the measuring devices is made more difficult by the fact that the gauges are as hard as glass, so no impacts can be made on them. The only way to put the test notes on the measuring devices is to use the data. However, this method has the disadvantage that the measuring devices are quickly covered with these notices and the tolerances applied to them become confusing. This inconvenience has now been remedied in the simplest way by the invention. The drawing shows the new device in FIGS. 1 and 2 with a snap gauge, and in FIGS. 3 and 4 with a caliber mandrel.
Das Meßgeräte erhält auf seiner Vorderseite eine Einsenkung b irgendwelcher Querschnittsform, in welche ein die Prüfungsvermerke tragendes Schildchen c eingelegt wird.The front of the measuring device has a depression b of any cross-sectional shape into which a label c bearing the test notes is inserted.
Zur Verhinderung des Beschädigtwerdens dieses Schiidchens wird über dasselbe noch eine durchsichtige Schutzplatte el aus Galalith, Glimmer o. dgl. gebracht. Als Sicherung gegen ein etwaiges Herausfallen dieser Teile wird der äußere Rand der Einsenkung b etwas eingezogen. Der die Nachprüfung der ' Meßgeräte ausführende Beamte führt die mit dem Datum der Prüfung und seinem Zeichen versehenen Schikichen bei sich, entfernt auf die einfachste Art das alte Schild und setzt dafür das neue Schild in das Meßgerät ein.To prevent the Damaged which this Schiidchens still a transparent protective plate from el Galalith, mica is the same o. Like. Accommodated. To prevent these parts from falling out, the outer edge of the depression b is drawn in somewhat. The officer carrying out the inspection of the measuring devices carries the locks with the date of the test and his mark, removes the old plate in the simplest way and inserts the new plate into the measuring device.
Das Auswechseln des Schildchens c erfolgt durch einen kleinen Stift o. dgl., der von rückwärts durch eine kleine im Meßgerät in der Einsenkung b vorgesehene Durchbohrung e geführt wird, wobei er das Schildchen c mitsamt der Schutzplatte d nach vorn herausdrückt. An Stelle der Durchbohrung e kann auch auf der Vorderseite des Meßgerätes a eine kleine Kimme f vorgesehen sein, um mittels eines Stiftes o. dgl. das Schildchen c und die Schutzplatte d leicht aus der Einsenkung b herausheben zu können.Replacing the scutellum is effected c o through a small pin. The like., The intended bore b of backwards by a small value in the instrument in the depression e is fed, wherein he c the tag together with the protective plate d forwardly pushes out. Instead of the through hole e , a small rear sight f can also be provided on the front of the measuring device a in order to be able to easily lift the label c and the protective plate d out of the recess b by means of a pin or the like.
