   #Vorwärtsarbeiten" der Maschine   anzeigt und gleichzeitig die Tourenzahl   der Propeller   welle registriert. 



   Die in den Nuten der Plunger vorhandene Luft bewirkt ein sanftes Gleiten der Plunger in den Rohren. 



   Sobald der Kolben 5 zurückgeht, beschleunigt er durch Verminderung dos Luftdruckes in der Leitung 24 die durch Eigengewicht erfolgende   Rückbewegung   des Plungers 16. 



   Beim Umsteuern der Maschine   nach #rückwärts" wird der Hahnkörper 26   so gestellt, dass die jeweilig von der Pumpe zusammengepresste Luft in die Rohrleitung 25 einströmen kann, wodurch, analog wie früher der   Zäh) er M,   jetzt der   "Rückwärts"-   Zähler 19 betätigt wird. 



   Es können auf einem Schiffe auch mehrere derartige Apparate an verschiedenen Stellen angeordnet werden ; ebenso lässt sich der Apparat bei anderen Maschinen und Anlagen zum Anzeigen der Bewegung verschiedener Organe benützen. 



   PATENT-ANSPRÜCHE 
1. Anzeigevorrichtung für die Umlaufszahl und Drehungsrichtung der Propellerwelle von Schiffen, bei der in zwei Röhren je ein von der Propellerwelle unter Vermittlung einer Luftpumpe angetriebener Plunger gleitbar ist, dadurch gekennzeichnet, dass die
Plunger mit an ihren oberen Enden vorgesehenen   Verlängerungen (20, 21)   stossweise auf zugehörige Zählwerke   (18,   19) einwirken.

 EMI2.1
   # Forward work "of the machine and at the same time registers the number of revolutions of the propeller shaft.



   The air present in the grooves of the plungers causes the plungers to slide smoothly in the pipes.



   As soon as the piston 5 moves back, it accelerates the return movement of the plunger 16, which takes place under its own weight, by reducing the air pressure in the line 24.



   When the machine is reversed to "# backwards", the valve body 26 is set so that the air compressed by the pump can flow into the pipeline 25, whereby, analogous to the counter M earlier, the "backwards" counter 19 is now operated becomes.



   It is also possible for several such devices to be arranged in different places on a ship; The apparatus can also be used in other machines and systems to display the movement of various organs.



   PATENT CLAIMS
1. Display device for the number of revolutions and the direction of rotation of the propeller shaft of ships, in which a plunger driven by the propeller shaft by means of an air pump is slidable in two tubes, characterized in that the
Plungers with extensions (20, 21) provided at their upper ends act in bursts on associated counters (18, 19).

 

Claims (1)

2. Anzeigevorrichtung für die Umlaufszahl und Drehungsrichtung der Propellerwelle von Schiffen nach Anspruch 1, dadurch gekennzeichnet, dass die Plunger (16, 17) in ihrer Mitte mit einer ringförmigen oder die Form eines Ringteiles aufweisenden Nut ver- sehen sind. 2. Display device for the number of revolutions and direction of rotation of the propeller shaft of ships according to claim 1, characterized in that the plunger (16, 17) in their Center are provided with an annular groove or the shape of a ring part.
