PATENTAMT.PATENT OFFICE.
Bei vielen Meßinstrumenten wird die Anzeigevorrichtung unter Einfluß einer Feder gestellt, welche sich z. B. bei steigendem Drucke proportional demselben spannt, so daß den unter sich gleich großen Mehrbelastungen oder wirkenden Druckeinheiten auch gleich große weitere Durchbiegungen entsprechen (Fig. i).In many measuring instruments, the display device is operated under the influence of a spring posed, which z. B. tensioned proportionally the same with increasing pressure, so that the additional loads or pressure units acting under the same size also have further deflections of the same size correspond (Fig. i).
Soll nun z. B. als Ersatz der Kurven beiShould z. B. as a replacement for the curves
ίο Dampfmessern nach Art der in der Patentschrift 94452 bezeichneten, die Durchbiegung der Feder α für jede weitere belastende Gewichtseinheit nicht dieselbe sein, so daß ζ. Β. die einzelnen Federungen Ordinaten entsprechen, welche eine Kurve d (Fig. 4) ergeben, so werden gemäß vorliegender Erfindung in bestimmten Abständen unter oder über der Feder α in der Anwendung auf die Zeigereinstellung bei Federwagen an sich bekannte Vorrichtungen b angeordnet, welche die Durchbiegung der Feder α bei fortschreitender Belastung dadurch entsprechend vermindern, daß sie die Feder in der Bewegung aufhalten und damit die wirksame Federlänge verringern.ίο Steam knives according to the type described in the patent specification 94452, the deflection of the spring α for each additional onerous weight unit not be the same, so that ζ. Β. the individual springs correspond to ordinates, which give a curve d (Fig. 4), so are according to the present invention at certain intervals below or above the spring α in the application to the pointer setting in spring trolleys known devices b arranged, which the deflection of the As the load progresses, reduce the spring α accordingly by stopping the spring from moving and thus reducing the effective spring length.
In der Ausführungsform nach Fig. 2 dienen unter den Federn angebrachte Stellschrauben b dem genannten Zweck.In the embodiment according to FIG. 2, adjusting screws b mounted under the springs serve the stated purpose.
Fig. ι zeigt die gleichmäßige Durchbiegung einer Feder α bei fortschreitender Belastung mit gleichen- Druckeinheiten; diese Federbewegung würde graphisch dargestellt eine ' gerade Linie c (Fig. 4) ergeben.Fig. Ι shows the uniform deflection of a spring α as the load progresses with the same pressure units; this spring movement would graphically result in a straight line c (Fig. 4).
Fig. 2 zeigt die allmählich abnehmende Durchbiegung der Feder α bei gleichmäßiger Weiterbelastung unter Anwendung der Anschläge b, welche ganz nach Belieben eingestellt werden können. Die Kurve d (Fig. 4) stellt diese Duchbiegungen graphisch dar.Fig. 2 shows the gradually decreasing deflection of the spring α with uniform further loading using the stops b, which can be adjusted as desired. Curve d (Fig. 4) shows these deflections graphically.
Fig. 3 zeigt eine Feder anderer Bauart mit den Anschlägen b. Fig. 3 shows a spring of a different type with the stops b.
