KLASSE 74: Signalwesen.CLASS 74: Signaling.
Die beim Rückgänge des Kolbens K durch die Ventile V angesaugte Luft wird beim Vorwärtsgange desselben comprimirt und durch den Lufttrichter T in den Windkessel W eingeführt. In dem letzteren befindet sich ein offener Kasten K, auf welchem durch die Schraube E drei gekuppelte Stahlfedern f F und i71 befestigt sind. Letztere gerathen unter der Einwirkung der comprimirten Luft in Schwingungen und erzeugen infolge ihres Vorbeischwingens an den sie unmittelbar rings umgebenden Kanten der in den Kasten eingeschobenen Schneidepla'ttchen P einen Ton, welcher durch den Schalttrichter S in die Atmosphäre geleitet wird. Die obere Zunge ist mit einem Schlitz versehen, durch welchen die comprimirte Luft gleichzeitig auch auf die unterste Zunge einwirkt. Der ganze vorwärts gehende Kolbenschub wird in auf einander folgenden langen und kurzen Intervallen ausgeführt, wie es das jedem Apparat beigefügte Alphabet für jeden einzelnen Buchstaben vorschreibt. Der Windkessel, sowie der Schalltrichter werden von einer Schutzhülse H umgeben. The sucked-in decreases of the piston through the valves V K compressed air is the same in the forward way and inserted through the venturi in the air chamber T W. In the latter there is an open box K on which three coupled steel springs f F and i 71 are fastened by the screw E. The latter start to vibrate under the influence of the compressed air and, as a result of their swinging past the edges of the cutting plates P inserted into the box, produce a sound which is passed through the switching funnel S into the atmosphere. The upper tongue is provided with a slit through which the compressed air acts simultaneously on the lower tongue. The entire forward thrust of the piston is carried out at successive long and short intervals, as the alphabet attached to each apparatus prescribes for each individual letter. The air chamber and the horn are surrounded by a protective sleeve H.
Unter dem Kasten K ist ein Luftsack L angebracht, in welchen die zwischen den Zungen und den Schneideplättchen hindurchgetriebene comprimirte Luft hineintritt, wodurch ein Anstofsen der schwingenden Zungen an den Windkessel verhindert werden soll.An air bag L is attached under the box K , into which the compressed air forced through between the tongues and the cutting plates enters, which is intended to prevent the vibrating tongues from sticking to the air chamber.
