      Grenztasterlehre    mit     nachstellbaren        Tastbolzen.       Die     Erfindung    betrifft eine     Grenztaster-          lehre    mit     nachstellbaren        Tastbolzen.     



  Die Erfindung besteht     darin,        dass    minde  stens einer der mit     Passsitz        in    die     Lehren-          s-chenkel    eingesetzten, nahezu .auf ihrer gan  zen Länge     glattwandigen        Tastbolzen    durch       eine        entfernbare        Weichmetallplombe    festge  halten ist, die in eine Bohrung quer zu der       Bolzenführung    eingelassen und einerseits mit  dem     Tastbolzen        tdurch        Riffeleingriff    verbun  den,

   .anderseits mittelst eines Vorsprunges im       Lehrensclienkel    gegen Verdrehung     gesichert     ist.  



  Die Erfindung ist in einem Ausführungs  beispiel in der Zeichnung dargestellt.  



  Als     solches    zeigt     Fig.    1 eine     Doppel-          rachenlehre,deren    einer Arm geschnitten ist,  um die Lagerung der     Tastbolzen    zu zeigen;       Fig.    2 zeigt in einem Schnitt,     rechtwinklig     zu dem in     Fig.    1 gelegt, die Plombe in ihrer  Lage, ehe sie geschlossen wird, und     Fig.    3  in einem ,gleichen Schnitt, nachdem sie ge  schlossen     ist.     



  In der Lehre 1 sitzen die     Tastbolzen    2,  und zwar je zwei in den einander gegenüber  stehenden Armen der Lehre. Quer zu den    Führungen der Bolzen ist im     Lehrenarm    eine  Bohrung 3 vorgesehen, welche einen etwas  grösseren Durchmesser aufweist, als der Ab  stand     zwischen    den beiden     Bolzenführungen     beträgt.

   Die beiden Bolzen     sind    .an der Stelle,  an der sie in die Bohrung 3 hineinragen, ge  riffelt, so dass eine     Weichmetallplombe    4, die  gemäss     Fig.    2 in die     Bohrung    3 hineingelegt  ist, nach -Zusammendrücken gemäss     Fig.    3 die  ganze Bohrung voll ausfüllt,     dabei    in die       Riffel    der Bolzen     eindringt    und auch in die  Nut 5. Letztere sichert -die Plombe     -gegen     unbeabsichtigte Verdrehung.  



  Auf diese     Weise    sind die     Tastbolzen     leicht in einer gewünschten Stellung festzu  legen, und es macht auch keine Schwierig  keiten, durch Entfernung der Plombe sie  nachzustellen.  



  Diese     Tastbolzen        können    so     bis    zur voll  ständigen Abnutzung aufgebraucht     werden,     wobei jede     gewählte        Stellung    durch die Ver  wendung von Plomben als Befestigungsmittel  gegen     missbräuchliche    Veränderung .gesichert  ist. Bei eingetretenem     Verschleiss    stösst man  .die Plomben aus, schiebt die Bolzen weiter  nach innen auf das frühere Rohmass, giesst      oder     drückt    die Plomben ein, worauf wieder  der Massschliff einsetzt.  



  Die     Erfindung    ist natürlich auch auf  Längenlehren und sonstige Lehren mit     na.ch-          stellbaren    Bolzen anwendbar.



      Limit switch gauge with adjustable probe pins. The invention relates to a limit switch gauge with adjustable feeler pins.



  The invention consists in that at least one of the feeler pins, which are inserted with a snug fit in the gauge legs and have almost their entire length smooth-walled, is held in place by a removable soft metal seal, which is inserted into a bore across the pin guide and on the one hand with connected to the feeler pin t by corrugation,

   .on the other hand, is secured against rotation by means of a projection in the gauge bracket.



  The invention is shown in an embodiment example in the drawing.



  As such, FIG. 1 shows a double rake gauge, one arm of which is cut to show the mounting of the feeler pins; Fig. 2 shows in a section, placed at right angles to that in Fig. 1, the seal in its position before it is closed, and Fig. 3 in a, same section after it is closed GE.



  In the teaching 1 sit the feeler pins 2, two in each of the opposite arms of the teaching. Transversely to the guides of the bolts, a hole 3 is provided in the gauge arm, which has a slightly larger diameter than the distance between the two bolt guides is.

   The two bolts are .at the point where they protrude into the bore 3, ge corrugated, so that a soft metal seal 4, which is placed in the bore 3 according to FIG. 2, after pressing together according to FIG fills, thereby penetrating into the corrugation of the bolts and also into the groove 5. The latter secures the seal against unintentional rotation.



  In this way, the feeler pins are easy to lay down in a desired position, and it is also easy to readjust them by removing the seal.



  These probe pins can be used up until they are completely worn out, with each selected position being secured against improper change by using seals as fastening means. When the seals are worn out, the seals are pushed out, the bolts are pushed further inwards to the previous rough dimensions, the seals are poured or pressed in, whereupon the made-to-measure cut starts again.



  The invention can of course also be applied to length gauges and other gauges with bolts that can be adjusted.
