1879.1879. Klasse 14.Class 14. H. MEYER in BIELEFELD. Ausklinkvorrichtung für Präcisions-Ventilsteuerungen für Dampfmaschinen. H. MEYER in BIELEFELD. Notching device for precision valve controls for steam engines. Patentirt im Deutschen Reiche vom 9. Mai 1879 ab.Patentirt in the German Empire from May 9, 1879 from. Die beiliegenden Zeichnungen stellen in der Ansicht, theilweisem Längenschnitt und im Grundrifs (worin der Deutlichkeit halber die Hebel nicht angegeben) einen Expansionsapparat für Dampfmaschinen dar, der die Expansionsschieber ersetzen und die Drosselung des Dampfes vermeiden soll. Derselbe kann sehr leicht an alten und neuen Dampfmaschinen angebracht werden.The attached drawings represent in elevation, partial longitudinal section and in Grundrifs (in which the levers are not indicated for the sake of clarity) an expansion apparatus for steam engines, which replace the expansion valve and the throttling of the Avoid steam. The same can very easily be attached to old and new steam engines will. In dem Gehäuse α sitzt ein doppelsitziges Ventil b, dessen Sitz durch die Schraube c in dem Gehäuse α befestigt ist. Das Ventil b hängt an einer Ventilstange d, auf welcher ein Kolben m angebracht ist, der sich in dem Luftcylinder g bewegt. Auf der Ventilstange d ist zwischen zwei Bunden h und i eine Hülse ν mit länglichem Auge angebracht und mit zwei auf der Welle k befestigten Hebeln / durch Zapfen verbunden. Auf der Welle k ist ein Segmentstück / angebracht, worin eine Stahlplatte mit einer Nase befestigt ist. In zwei auf der Welle k sich drehenden Hebeln e e ist eine mit einer Stahlplatte versehene FaIIe^ gelagert. Diese Hebel e e sind durch die Lenkerstange 0 mittelst Bolzen mit den auf der Welle η befestigten Hebeln r verbunden. Durch den Hebel q auf der Welle n, welcher mit einem eingeschraubten Zapfen ζ versehen ist, wird das Ventil mit den Steuerstangen an der Dampfmaschine verbunden, bei jedesmaliger Umdrehung der Dampfmaschine zweimal geöffnet und geschlossen. .In the housing α sits a double-seated valve b, the seat of which is fixed in the housing α by the screw c. The valve b is suspended from a valve rod d on which a piston m is mounted, which moves in the air cylinder g . A sleeve ν with an elongated eye is attached to the valve rod d between two collars h and i and is connected to two levers / fastened on the shaft k by pins. A segment piece /, in which a steel plate is fastened with a nose, is attached to the shaft k. A case provided with a steel plate is mounted in two levers ee rotating on the shaft k. These levers ee are connected to the levers r attached to the shaft η by means of bolts through the handlebar 0. The valve is connected to the control rods on the steam engine by means of the lever q on the shaft n, which is provided with a screwed-in pin ζ , and is opened and closed twice with each rotation of the steam engine. . Das frühere oder spätere Schlieisen des Ventils wird durch die oben am Gehäuse gelagerte Welle w, worauf zwei Hebel t und s befestigt sind, bewerkstelligt. Der Hebel t wird mit dem Regulator in Verbindung gebracht und bewegt die mit dem Hebel s verbundene Rolle u auf und nieder, wodurch die Falle p früher oder später ausklinkt.The earlier or later closing of the valve is brought about by the shaft w mounted on top of the housing, to which two levers t and s are attached. The lever t is brought into connection with the regulator and moves the roller u connected to the lever s up and down, as a result of which the latch p disengages sooner or later. Pat en τ-Anspruch:Pat en τ claim: Der durch Zeichnung und Beschreibung erläuterte Expansionsapparat. The expansion apparatus explained by drawing and description.
