Patentirt im Deutschen Reiche vom 15. April 1881 ab. Patented in the German Empire on April 15, 1881.

Der Apparat soll zum Probiren von Manometern und Vacuummetern im Bureau dienen.The apparatus is intended to be used for testing manometers and vacuum gauges in the office.

Die Compression der Wassersäule erfolgt durch das Anziehen einer Schraube; das Vacuum wird durch Zurückdrehen derselben erzeugt. The water column is compressed by tightening a screw; the vacuum is generated by turning it back.

Fig. ι der beiliegenden Zeichnung giebt einen Längsschnitt und Fig. 2 einen Querschnitt mitten durch den Apparat.Fig. 1 of the accompanying drawing gives a longitudinal section and Fig. 2 shows a cross section right through the machine.

Fig. 3 stellt zwei Modificationen in der Anordnung des Communicationsrohres dar, wozu die Fig. 4 und 5 die Querschnitte bilden.Fig. 3 shows two modifications in the arrangement of the communications tube, including Figures 4 and 5 form the cross-sections.

Durch Drehung der Schraubenspindel α wird in dem Druckrohr c der Kolben b in der entsprechenden Richtung bewegt, d. h. also in der Richtung des Pfeiles bei der Prüfung von Manometern und umgekehrt für Vacuummeter.By turning the screw spindle α , the piston b in the pressure tube c is moved in the corresponding direction, ie in the direction of the arrow when checking pressure gauges and vice versa for vacuum gauges.

Infolge des Anziehens der Schraube α wird das Wasser mit bedeutender Kraft in das auf dem Ansatz d aufgeschraubte Controlmanometer gedrückt, welches durch den Kanal i mit dem das Druckrohr c einschliefsenden Communicationsrohr η in Verbindung steht. Das zu prüfende Manometer wird auf den Ansatz g aufgesetzt und communicirt durch den Kanal e mit n. Der Stutzen f dient zum Füllen des Apparates mit Wasser und zum Entleeren, was durch die entsprechende Stellung des Hahns h veranlafst wird. Der Hahn k sperrt den Kanal e ab.As a result of the tightening of the screw α , the water is pressed with considerable force into the control manometer screwed onto the attachment d, which is connected through the channel i to the communications pipe η enclosing the pressure pipe c . The manometer to be checked is placed on the attachment g and communicates through the channel e with n. The connection f is used to fill the apparatus with water and to empty it, which is caused by the corresponding position of the tap h . The cock k blocks the channel e .

Bei der Prüfung von Vacuummetern wird der Kolben b durch Linksdrehen der Spindel a zurückgezogen und dadurch das nöthige Vacuum erzeugt.When checking vacuum gauges, the piston b is withdrawn by turning the spindle a to the left, thereby creating the necessary vacuum.

Die Anordnung des Communicationsrohres n, wie sie in den Fig. 3, 4 und 5 dargestellt ist, hat keinen weiteren Einflufs auf die Wirkung des Apparats, sondern bildet nur einfache, in den entsprechenden Fällen anwendbare Zweckmäfsigkeitsabänderungen. The arrangement of the communications tube n, as it is shown in FIGS. 3, 4 and 5, has no further influence on the operation of the apparatus, but only forms simple changes in expediency which can be used in the corresponding cases.
