PATENTAMT.PATENT OFFICE.
•Die im Patent 193904 beschriebene,- elektrisch wirkende Feinmeßvorrichtung' ist gemäß vorliegender Erfindung dahin weiter ausgebildet, daß die Zurücklegung mehrerer hintereinander folgender Wegstrecken des Fühlers durch Stromschließen bzw. Unterbrechen angezeigt wird.• The one described in patent 193904 - electrical acting precision measuring device 'is further developed according to the present invention, that the covering of several successive distances of the sensor by current connection or interruption is shown.
Die beiliegenden Zeichnungen veranschaulichen eine Ausführungsform.The accompanying drawings illustrate an embodiment.
Fig. ι bis 3 zeigen die Ausführung in senkrechtem Schnitt, wagerechtem Schnitt und Endansicht bei teilweisem Schnitt, wobei die einzelnen Teile ebenso bezeichnet sind wie die entsprechenden Teile der Einrichtung des Hauptpatentes, jedoch führt der stromleitende Draht i nicht zum Fühlerkopf a, sondern direkt zur Stromquelle. Der Fühlerkopf ist deshalb nicht mehr isoliert, sondern bildet mit dem Fühler selbst ein Ganzes. Auch ist die Isolierbüchse h und der Draht k in Wegfall gekommen.Fig. Ι to 3 show the execution in vertical section, horizontal section and end view with partial section, the individual parts are labeled as the corresponding parts of the device of the main patent, but the conductive wire i does not lead to the sensor head a, but directly to Power source. The sensor head is therefore no longer isolated, but forms a whole with the sensor itself. The insulating sleeve h and the wire k have also been omitted.
Der Unterschied zwischen dem Gegenstand des Hauptpatentes und der vorliegenden Ausführung besteht nun darin, daß der Strom-Schluß nicht im Augenblick der ersten Berührung des Fühlers α mit dem Werkstück, sondern erst dann stattfindet, wenn das Fiihlergehäuse/ schon eine Wegstrecke zurückgelegt hat. Zu diesem Zwecke ist der bei dem Gegenstande des Hauptpatentes benutzte 3<> Arm s durch einen z. B. dreikantigen, isoliert getragenen Arm u ersetzt, der mit Zahnlücken einer in den Stromkreis eingeschalteten Schiene t zusammenwirkt, und zwar in folgender Weise:The difference between the subject matter of the main patent and the present embodiment is that the current does not terminate at the moment when the sensor α touches the workpiece for the first time, but only when the sensor housing / has already covered a distance. For this purpose, the 3 <> arm s used in the subject matter of the main patent is replaced by a z. B. replaced triangular, insulated arm u , which interacts with tooth gaps of a rail connected in the circuit t , in the following way:
Der Strom wird durch i, u, t, η erst geschlossen , wenn der Arm u, der sich zuerst in der Zahnlücke t'-f2 der Schiene t befindet, die Kante ί2 berührt. Während des Weges t'2-t3 bleibt der Strom geschlossen, während des Weges i3 -1* dagegen, wieder unterbrochen, bis er bei i4 wieder geschlossen wird.The current is only closed by i, u, t, η when the arm u, which is first in the tooth gap t'-f 2 of the rail t , touches the edge ί 2. During the path t ' 2 -t 3 the current remains closed, while the path i 3 - 1 *, on the other hand, is interrupted again until it is closed again at i 4.
Das zu messende Werkstück braucht nicht elektrisch leitend zu sein.The workpiece to be measured does not need to be electrically conductive.
