Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bisher benutzte man zum Messen der Durchmesser von Zylindern oder Hohlkörpern, in welchen sich durch ihren Gebrauch Unebenheiten eingearbeitet hatten und die deshalb neu ausgebohrt werden mußten, zirkelähnliche Taster mit zwei Schenkeln; das hatte aber den Übelstand, daß der Taster, haupt-• sächlich bei tieferen Hohlkörpern, sehr leicht schief eingesetzt wurde.So far, one used to measure the diameter of cylinders or hollow bodies, in which bumps had worked through their use and therefore had to be drilled out again, circle-like buttons with two legs; this had but the disadvantage that the feeler is very light, especially in the case of deeper hollow bodies was inserted crookedly.
ίο Bei dem den Gegenstand der Erfindung bildenden Taster wird dieser Ubelstand dadurch vermieden, daß die Meßspitzen innerhalb eines federnden, geschlitzten Ringes angeordnet sind, welcher sich an den zu messenden Innenraum anlegt und vermöge seiner Breite ein schiefes Einsetzen des Tasters verhindert. Durch die Anbringung eines Schiebers wird auch die Längsentfernung der gemessenen Stelle vom Rande des Zylinders, aus bestimmt.ίο In the case of the button forming the subject of the invention, this Ubelstand is thereby avoided that the measuring tips are arranged within a resilient, slotted ring are, which is applied to the interior space to be measured and due to its width an oblique insertion of the Button prevented. Attaching a slider also increases the lengthways distance the measured point from the edge of the cylinder.
Für den angegebenen Zweck eignet sich der in der Zeichnung in den Fig. 1, 2 und 3 in Seitenansicht, Vorderansicht und einem Qnerschnitte dargestellte Taster.The one in the drawing in FIGS. 1, 2 and 3 is suitable for the stated purpose Button shown in side view, front view and a cross-section.
Er besteht aus dem federnden Führungsringe α mit zwei angearbeiteten Führungen b und c, in welchen durch die Federt zwei an ihren inneren Enden mit Scheiben h und k versehene Bolzen e und f nach außen gedrückt werden. Mittels Stifte i und g sind an beiden Bolzen e und f Zeiger Z und m befestigt, die sich um die Achse η drehen und den Halbmesser bezw. den Durchmesser an der am Segmente 0 angebrachten Teilung anzeigen. Das Segment ο wird durch eine Stange, welche in einem Steg q befestigt ist, getragen. Um ein Ausweichen der Feder d zu verhindern, ist über dieselbe sowie über die Führungen b und c eine Hülse t geschoben und in geeigneter Weise befestigt. Die Hülse ist an ihrer Vorderseite mit einem Schlitz versehen, um ein Hin- und Hergleiten der Zeiger zu gestatten. Die Stifte s und r verhindern das zu weite Ausspannen des Tasters. Der Schieber u, welcher an der Stange ρ angebracht ist, kann an derselben auf- und abwärts bewegt und durch die Stellschraube ν festgestellt werden, so daß an der Längsteilung w die Entfernung des gemessenen Durchmessers vom Rande des Hohlkörpers abgelesen werden kann.It consists of the resilient guide rings α with two attached guides b and c, in which two bolts e and f, which are provided with washers h and k at their inner ends, are pressed outwards by the springs. By means of pins i and g are attached to both bolts e and f pointers Z and m , which rotate around the axis η and the radius BEZW. show the diameter at the graduation on segment 0. The segment o is carried by a rod which is fastened in a web q. In order to prevent the spring d from evading, a sleeve t is pushed over the same and over the guides b and c and fastened in a suitable manner. The sleeve is slotted on its front to allow the pointers to slide back and forth. The pins s and r prevent the button from being extended too far. The slide u, which is attached to the rod ρ , can be moved up and down on the same and fixed by the adjusting screw ν , so that the distance of the measured diameter from the edge of the hollow body can be read on the longitudinal graduation w.
