Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei dem praktischen Gebrauche der Platten- und Röhrenfedermanometer besteht ein großer Übelstand darin, daß sich die elastischen Eigenschaften des Druckorganes im Laufe der Zeit ändern, und daß die Manometer infolgedessen unrichtig anzeigen. Diesem Übelstande kann durch einfache Verschiebung der gesamten Skala niemals abgeholfen werden, da sich die Werte der verschiedenen Drücke stets inIn the practical use of the plate and tube spring pressure gauges, there is a large one The disadvantage is that the elastic properties of the pressure element in the course of Change the time and the pressure gauges will read incorrectly as a result. This evil can never be remedied by simply shifting the entire scale, since the values of the various pressures are always in

ίο verschiedenem Maße ändern, d. h. das Manometer wird z. B. nur für hohe Drücke falsch, während es für einen anderen Teil der Skala nur unerhebliche oder gar keine Abweichungen zeigt.ίο change different dimensions, d. H. the manometer is z. B. is wrong only for high pressures while it is wrong for another part of the scale shows only insignificant or no deviations.

Diesem Übelstande kann nun eine in ihren Einzelwerten einstellbare, bei Meßinstrumenten an sich bekannte Skala abhelfen. Das Neue ist die konstruktive Ausbildung.This inconvenience can now be compensated for by measuring instruments which can be adjusted in their individual values remedy known scale. The new thing is the constructive training.

Die Skala ist hier zusammengesetzt aus einer Anzahl von fächerblattartigen Blechlamellen I, welche am einen Ende eine Bohrung besitzen, durch die eine hohle Welle h gesteckt ist, durch welche die Zeigerwelle hindurchgeführt wird. Die Blechlamellen sind aus weißem Metall, z. B. Aluminium, hergestellt; in jede Lamelle ist ein radialer Strich und eine Ziffer eingeprägt oder eingraviert und mit schwarzem Lack ausgefüllt. Sämtliche Lamellen liegen mit ihrem äußeren Rande zwischen zwei am Manometergehäuse befestigten Leisten m n, von denen die vordere (m) eine genügende Anzahl von Stellschrauben besitzt, welche zum Festklemmen der Lamellen dienen, sofern sie nicht bereits durch Reibung genügend gehalten werden. An die Stelle der hinteren Leiste kann auch eine durchgehende Platte treten.The scale is composed here of a number of fan-leaf-like sheet metal lamellas I, which have a bore at one end through which a hollow shaft h is inserted, through which the pointer shaft is passed. The sheet metal lamellas are made of white metal, e.g. B. aluminum, made; A radial line and a number are embossed or engraved into each lamella and filled in with black lacquer. All lamellas lie with their outer edge between two strips mn attached to the manometer housing, of which the front (m) has a sufficient number of adjusting screws which are used to clamp the lamellas if they are not already held sufficiently by friction. A continuous plate can also take the place of the rear bar.
