Description
Schienentemperatur-MeEgerät.
Das Verfahren, die Schienentemperaturen durch Messung der Temperatur einesl Ver- gleichsstückes, das neben die zu kontrollie- rende Schiene gelegt wird, zu ermitteln, ist bekannt. Die bis heute benutzten Geräte weisen zur Temperaturmessung eine Bohrung auf, in die zur Temperaturmessung ein Quecksilberthermometer gesteckt wird. Zum Ablesen des Temperaturwertes muss das Thermometer aus der Bohrung herausgenommen werden. Abgesehen davon, dass diese meus- methode umständlich ist und auch häufig zum Bruch des Thermometers führt, ist sie vor allem ungenau, da sich das Thermometer besonders in kalten Jahreszeiten an der Luft rasch abkühlt.
Die vorliegende Erfindung will diesen Pbelstanden abhelfen durch Schaffung eines Schienentemperatur-Messgerätes mit fest ein gebautem Thermometer.
Die Zeichnung zeigteinAusführungs- beispiel des Erfindungsgegenstandes, und zwar im Seitenriss, teilweise geschnitben, und in Stirnansicht.
1 ist das Vergleichsstück, etwa in der Form eines Eisenbahn-Schienenstückes. In seinem Kopf ist in einer Längsbohrung 2 ein Metallthermometer 3 eingebaut, das von der Stirnseite des Vergleichsstückes aus direkt abgelesen werden kann. 4 ist ein Handgriff, der das bequeme Tragen des MeBgeräbes ge stattet. Dieses MeBgerät weist alle oben angeführten Nachteile nicht auf und erlaubt, die Temperatur der zu kontrollierenden.
Schiene, wie die Erfahrung zeigt, bis auf einen halben Grad genau zu bestimmen.
PATENTANSPRUCH : Schienentemperatur-Messgerä. t, dadurch gekennzeichnet, daB das Thermometer in einem Vergleichsetück, das bestimmt ist, wenigstens angenähert den gleichen Wärmever hä. ltnissen ausgesetzt zu werden wie die zu kontrollierende Schiene, fest eingebaut ist.
UNTERANSPRUCHE :
1. Schienentemperatur-Messgerät nach Pa tentanspruch, dadurch gekennzeichnet, dass das Thermometer in einer Längsbohrung des Vergleichsstuckes steckt und an einer Stirn- seite desselben abgelesenwerden kann.
2. Schienentemperatür-Messgerät nach Pa- tentanspruch, dadurch gekennzeichnet, daB es ein Metallthermometer aufweist.

Rail temperature measuring device.
The method of determining the rail temperatures by measuring the temperature of a reference piece that is placed next to the rail to be checked is known. The devices used to this day have a hole for temperature measurement into which a mercury thermometer is inserted for temperature measurement. To read the temperature value, the thermometer must be removed from the hole. Apart from the fact that this measuring method is cumbersome and often leads to breakage of the thermometer, it is above all inaccurate because the thermometer cools down quickly in the air, especially in cold seasons.
The present invention aims to remedy this problem by creating a rail temperature measuring device with a built-in thermometer.
The drawing shows an exemplary embodiment of the subject matter of the invention, specifically in side elevation, partially in section, and in front view.
1 is the comparison piece, for example in the form of a railway track piece. In its head, a metal thermometer 3 is installed in a longitudinal bore 2, which can be read directly from the front of the comparison piece. 4 is a handle that makes it easy to carry the measuring device. This measuring device does not have all of the disadvantages listed above and allows the temperature of the to be controlled.
As experience shows, it can be determined to within half a degree.
PATENT CLAIM: Rail temperature measuring devices. t, characterized in that the thermometer in a comparison piece which is determined has at least approximately the same heat ratio. to be exposed to conditions such as the rail to be controlled is permanently installed.
SUBClaims:
1. Rail temperature measuring device according to the patent claim, characterized in that the thermometer is inserted in a longitudinal bore of the reference piece and can be read on one end of the same.
2. Rail temperature measuring device according to patent claim, characterized in that it has a metal thermometer.
