EDUARD RAU m BRÜSSEL. Von innen beleuchtbares Manometer.EDUARD RAU m BRUSSELS. Manometer that can be illuminated from the inside.
Patentirt im Deutschen Reiche vom io. Februar 1878 ab. Längste Dauer: 10. November 1886.Patented in the German Empire by the io. February 1878 onwards. Longest duration: November 10, 1886.
Das in der beiliegenden Zeichnung dargestellte Manometer ist ein solches, wie es gewöhnlich bei Locomotiven und stationären Dampfmaschinen angewendet und von Schäffer & Budenberg und anderen Fabrikanten geliefert wird.The pressure gauge shown in the accompanying drawing is the usual one Used in locomotives and stationary steam engines and supplied by Schäffer & Budenberg and other manufacturers will.
Für den vorliegenden Zweck erhält das Manometer nach vorn eine Verlängerung α al· b aus schwachem Blech mit seitlicher Scharnierthür; der in dem Gehäuse befindliche Mechanismus aber wird durch ein Schutzblech dd von der Verlängerung vollständig abgeschlossen. Mittelst einer kleinen Kupplung e wird auch die Axe, welche die Nadel trägt, und zwar der Gehäuseverlängerung entsprechend, verlängert. Das Zifferblatt //, welches die Scala trägt, ist eine transparente Glasplatte, welche von einem Gummiring g g umgeben ist, um die Platte bei starken Stöfsen, wie sie oft bei Locomotiven vorkommen, gegen das Zerbrechen zu sichern. Zum Schütze der Nadel befindet sich vor dem Zifferblatte noch die Glasplatte h, welche wie gewöhnlich eingesetzt und befestigt wird.For the present purpose, the manometer has an extension α al · b towards the front made of thin sheet metal with a hinged door on the side; the mechanism located in the housing, however, is completely closed off from the extension by a protective plate dd. By means of a small coupling e , the axis that carries the needle is lengthened in accordance with the extension of the housing. The dial //, which carries the scale, is a transparent glass plate, which is surrounded by a rubber ring gg , in order to secure the plate against breaking in the event of strong bumps, as often happens with locomotives. To protect the needle, there is still the glass plate h in front of the dial, which is inserted and fastened as usual.
An dem Schutzblech d d wird eine schwalbenschwanzförmig gebildete Unterstützung i für die Weifsblechlampe k, welche auch in der Vorderansicht punktirt angegeben ist, befestigt. Diese Lampe wird durch die Scharnierthür c eingeschoben; denn diese Thür ist grofs genug, um nicht nur die Lampe mit der Hand ein- und ausschieben, sondern auch den an der Rückseite des matten transparenten Zifferblattes etwa angesetzten Schmutz abwischen zu können. Um der Lampe Luft zur Verbrennung zuzuführen, sind unten im Gehäuse kleine Löcher //( angeordnet, und damit der starke Luftzug bei Locomotiven nicht ein Verlöschen der Lampe bewirken kann, ist oben auf dem Gehäuse ein sogenannter Windfang, aus zwei kreuzweise in einander gesteckten Halbcylindern m und m' aus Blech gebildet, angebracht.A dovetail-shaped support i for the white sheet metal lamp k, which is also indicated dotted in the front view, is attached to the protective plate dd. This lamp is pushed in through the hinge door c; for this door is big enough not only to slide the lamp in and out by hand, but also to wipe off any dirt that may have stuck to the back of the matt, transparent dial. In order to supply the lamp with air for combustion, small holes // (are arranged at the bottom of the housing, so that the strong draft of air in locomotives cannot cause the lamp to go out, there is a so-called vestibule on top of the housing, made of two half-cylinders inserted crosswise into one another m and m 'formed from sheet metal, attached.
Diese Halbcylinder gestatten zwar durch Oeffnungen in der oberen Gehäusewand und durch Schlitze in ihren Mänteln den Verbrennungsgasen den nöthigen Abzug, schützen dagegen die Flamme vor zu starkem Luftzug.These half-cylinders allow through openings in the upper housing wall and protect the flue gases from the necessary exhaust by means of slits in their coats on the other hand the flame from too strong a draft.
Die hier beschriebene Einrichtung läfst sich bei jedem Manometer, jedem Vacuummeter u. s. w. mit Leichtigkeit anbringen.The device described here works with every manometer, every vacuum meter and so on. attach with ease.
