Verbesserungen an Wassermessern.Improvements to water meters.

Patentirt im Deutschen Reiche vom 19. August 1877 ab. Längste Dauer: 10. September 1890.Patented in the German Empire on August 19, 1877. Longest duration: September 10, 1890.

Der in beiliegender Zeichnung dargestellte Wassermesser hat folgende besondere Eigenthümlichkeiten: The water meter shown in the accompanying drawing has the following special features:

ι. Das vom Wasser bewegte Triebrad, dessen Umdrehungszahl der Messung zu Grunde liegt, unterscheidet sich von den bis jetzt angewendeten derartigen Triebrädern dadurch, dafs es mit einer Innenwand w, sowie mit oben und unten angebrachten, horizontalen Begrenzungswänden W1 versehen ist, welche dazu dienen, dem durch den Apparat fliefsenden Wasser einen ganz bestimmten und constanten Querschnitt zu geben, so dafs auch bei veränderlicher Geschwindigkeit das durchfliefsende Wasserquantum immer genau proportional der Umdrehungsgeschwindigkeit bleibt.ι. The drive wheel moved by the water, the number of revolutions of which is the basis of the measurement, differs from the drive wheels of this type that have been used up to now in that it is provided with an inner wall w as well as with horizontal boundary walls W 1 attached above and below, which serve to To give the water flowing through the apparatus a quite definite and constant cross-section, so that even when the speed changes, the quantity of water flowing through always remains exactly proportional to the speed of rotation.

2. Das Wasser bewegt sich vom Eintritt in den Wassermesser bis zum Austritt aus demselben in einer horizontalen Ebene, wodurch die Ablagerung von Unreinigkeiten ausgeschlossen und aufserdem das Einschalten des Wassermessers in die Leitung wesentlich erleichtert wird, was bei anderen Apparaten dieser Art nur dadurch erreicht werden konnte, dafs das Wasser auf verticalen Umwegen wieder in die Horizontale der Eintrittsöffnung geführt wurde.2. The water moves from entering the water meter to leaving it in a horizontal plane, which eliminates the build-up of impurities and it also makes it much easier to switch on the water meter in the pipe becomes what could only be achieved with other apparatus of this kind by the fact that the water is led back to the horizontal of the inlet opening on vertical detours became.

3. Das ein- und ausströmende Wasser übt auf das zur Messung dienende und vom Wasser bewegte Rädchen nur seitlichen Druck aus und zwar wird hierbei, da der Druck symmetrisch auf beiden Seiten der Peripherie erfolgt, keinerlei seitliche Reibung an der Axe des Rades hervorgerufen. Ein Druck in verticalem Sinne findet nicht statt und es besteht demnach nur für den unteren Zapfen der Axe noch diejenige Reibung, welche durch das Eigengewicht des Rädchens hervorgebracht wird. Da diese so unbedeutend ist, dafs man davon absehen kann, so bleibt hiernach für das Wasser bei seinem Durchgang durch den Messer nur das Trägheitsmoment des Rädchens zu überwinden.3. The inflowing and outflowing water exercises on and off the water used for the measurement Moving cogs only exert pressure from the side and this is because the pressure is symmetrical takes place on both sides of the periphery, no lateral friction is caused on the axis of the wheel. There is no pressure in the vertical sense and therefore it only exists for the the lower journal of the axis still has the friction caused by the weight of the wheel is produced. Since this is so insignificant that one can disregard it, it remains hereafter only the moment of inertia of the water as it passes through the knife To overcome the little wheel.

Als neu und eigenthümlich ist besonders hervorzuheben :Particularly noteworthy as new and peculiar are:

1. Damit die in den Mefscylinder ein- und ausströmenden Wassermassen in gleichen Abständen von einer gemeinsamen horizontalen Symmetrieebene aneinander vorbeigeführt werden können, ist an einer Stelle, wie aus dem Schnitt ef ersichtlich, der Ausströmungskanal durch den Einströmungskanal hindurchgeführt. 1. So that the water masses flowing into and out of the Mefscylinder can be guided past each other at equal distances from a common horizontal plane of symmetry, the outflow channel is passed through the inflow channel at one point, as can be seen from the section ef.

2. Das Transmissionswerkehen, welches die Umdrehungen des Triebrädchens auf das Zählwerk überträgt, ist dadurch wesentlich vereinfacht worden, dafs es an einem einzigen kleinen Bockgestell montirt ist.2. The transmission works, which the rotations transfers the pinion to the counter, is thereby significantly simplified that it is mounted on a single little frame.

3. Die technischen Schwierigkeiten, welche sich für den Hauptkörper, besonders für den Gufs der Kanäle herausstellen würden, sind dadurch beseitigt, dafs die abschliefsende Innenwand durch eine eingeschobene ringförmige Büchse, in der sich dann zugleich auch die Ein- und Äusströmungsschlitze leicht bearbeiten lassen, gebildet wird.3. The technical difficulties which arise for the main body, especially for the Gufs of the canals are eliminated by the fact that the final inner wall by an inserted ring-shaped sleeve, in which the inlet and outlet slots are also easily machined at the same time let is formed.
