Description

Wasserwaage mit Beleuchtungsvorrichtung. Die Erfindung betrifft eineWasserwaage mit elektrischer Beleuchtung, bei welcher sich die Luftblase außerordentlich deutlich von der Flüssigkeit abhebt, so daß die Benutzung der Vorrichtung wesentlich erleichtert,ist. An der Stirnseite des die Flüssigkeit enthaltenen Rohr es ist eine Glühlampe angebracht, so daß die Flüssigkeit von innen her erleuchtet wird. Dadurch wird das klare Abheben der Luftblase erzielt.Spirit level with lighting device. The invention relates to a spirit level with electric lighting, in which the air bubble is extremely clear stands out from the liquid, so that the use of the device is much easier. A light bulb is attached to the end of the tube containing the liquid, so that the liquid is illuminated from within. This will make the clear take off of the air bubble.

Es ist schon früher vorgeschlagen worden, Wasserwaagen mit elektrischer Büleuchtung zu versehen. Zu dem Zweck wurde mit dernGehäuse der Wasserwaage eine kleine elektrische Batterie verbunden und über der Stelle des Flüssigkeitsrohres, an welcher die Luftblase einspielen soll, eine Glühlampe angebracht. Diese Beleuchtung der Luftblase von oben ergibt aber nicht eine so gute U-irkung, wie sie nach der Erfindung durch innere Erleuchtung der Flüssigkeit erzielt wird.It has been proposed before to use electric levels To provide illumination. For this purpose a small electric battery connected and over the place of the liquid pipe, A light bulb is attached to which the air bubble is supposed to play. This lighting However, the air bubble from above does not have as good an effect as it does after the Invention is achieved through inner enlightenment of the liquid.

In der Zeichnung ist eine Ausführungsform einer Wasserwaage teilweise im Schnitt dargestellt.Part of the drawing is an embodiment of a spirit level shown in section.

In dem auf der Leiste la befestigten Rohr a, welches das Glasrohr b umschließt und mit einem Ausschnitt c zum Sichtbarmachen der Luftblase d versehen ist, ist eine Glühlampe e angeordnet, deren Batterie f sich in einem am Rohr befestigten Gehäuse g befindet. Das Licht der Lampe durchdringt die gesamte Flüssigkeitssäule, und es entstehen hell leuchtende gut sichtbare Ränder der Luftblase. Gegebenenfalls känn man durch Wahl einer farbigen Glühlampe oder farbiger Flüssigkeit die Wirkung erhöhen. An incandescent lamp e, the battery f of which is located in a housing g fastened to the tube, is arranged in the tube a fastened on the bar la, which surrounds the glass tube b and is provided with a cutout c to make the air bubble d visible. The light from the lamp penetrates the entire column of liquid, and brightly shining, easily visible edges of the air bubble are created. If necessary, you can increase the effect by choosing a colored light bulb or colored liquid.
