KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Rachenlehren, bei denen die auswechselbaren Meßbacken durch in dem Lehrenkörper gelagerte Schrauben befestigt sind, sind bekannt. Bei diesen bekannten Rachenlehren ist die mit Gewinde versehene Bohrung, welche zur Aufnahme des Gewindebolzens der Befestigungsschraube dient, unmittelbar in der Meß backe angeordnet, was den Mangel hat, daß die Meßbacken an den Stellen, wo die Bohrungen sich befinden, so stark geschwächt werden, daß sie sich bei dem darauf folgenden Härten derart stark verziehen, daß eine genaue Meßfläche nicht mehr zu erreichen ist.Jaw gauges, in which the interchangeable measuring jaws through in the gauge body stored screws are attached are known. With these known throat gauges is the threaded hole which is used to receive the threaded bolt of the fastening screw serves, arranged directly in the measuring jaw, which has the defect that the measuring jaws in the places where the Bores are so weakened that they are in the next Hardening is so distorted that an exact measuring surface can no longer be achieved is. J5 Die vorliegende Erfindung bezieht sich auf Rachenlehren mit auswechselbaren Meßbacken nach dem Patent 187269, bei denen die mit einem Schaft und Gewinde versehenen Meßbacken durch Muttern mit dem Lehrenkörper verbunden sind. Die bekannte Anordnung hat den Mangel, daß der Schaft, welcher gleichzeitig als Schraubenbolzen für die Befestigungsmutter dient, infolge seines geringen Durchmessers an der Stelle, wo er in die Meßbacke übergeht, beim Härten sehr leicht Sprünge erhält.J5 The present invention relates to Snap gauges with interchangeable measuring jaws according to patent 187269, in which the with a shank and thread provided measuring jaws by nuts with the gauge body are connected. The known arrangement has the shortcoming that the shaft, which at the same time acts as a screw bolt for the fastening nut serves, due to its small diameter at the point where it merges into the measuring jaw, very easily during hardening Gets jumps. Das Wesen der Erfindung besteht darin, daß der Schaft der Meßbacken, welcher zur Aufnahme der Gewindebolzen der Befestigungsschrauben dient, mit Innengewinde versehen ist.The essence of the invention is that the shaft of the measuring jaws, which for Serves to accommodate the threaded bolts of the fastening screws, provided with an internal thread is. Die Zeichnung zeigt den Erfindungsgegenstand in einem Ausführungsbeispiel, und zwarThe drawing shows the subject matter of the invention in one embodiment, namely Fig. ι eine Rachenlehre in der Seitenansicht, -Fig. Ι a throat gauge in the side view, Fig. 2 eine Einzelheit in vergrößertem Maßstabe. 2 shows a detail on an enlarged scale. Die Meßbacke 1 ist mit einem Ansatz 2 versehen, in dessen Bohrung 3 die in dem Lehrenkörper 4 gelagerte Schraube 5 eingreift. Durch Anziehen der Schraube 5 werden die unteren Flächen 6, 7 der Meßbacken gegen den Lehrenkörper geschoben und so die Meßbacke in ihrer Lage gehalten. Damit die Meßbacke beim Anziehen der Schraube 5 sich nicht gegenüber dem Lehrenkörper verdrehen kann, ist in dem Lehrenkörper ein Zapfen 8 vorgesehen, welcher in eine Aussparung der Meßbacke eingreift und so dieselbe gegen Verdrehung sichert.The measuring jaw 1 is provided with a shoulder 2, in the bore 3 in the Gauge body 4 mounted screw 5 engages. By tightening the screw 5, the lower surfaces 6, 7 of the measuring jaws pushed against the gauge body and so the measuring jaw held in place. So that the measuring jaw when tightening the screw 5 cannot rotate with respect to the gauge body, there is a pin 8 in the gauge body provided, which engages in a recess of the measuring jaw and so the same against rotation secures. Paten τ-Anspruch:Sponsorship τ claim: Rachenlehre mit auswechselbaren Meßbacken nach Patent 187269, dadurch gekennzeichnet, daß der Schaft (2) der Meßbacken, welcher zur Aufnahme der Gewindebolzen (5) der Befestigungsschrauben dient, mit Innengewinde versehen ist.Snap gauge with exchangeable measuring jaws according to patent 187269, characterized in that that the shaft (2) of the measuring jaws, which is for receiving the threaded bolts (5) of the fastening screws serves, is provided with an internal thread.
