Description

KAISERLICHESIMPERIAL

PATENTAMTPATENT OFFICE

Das Instrument bezweckt, bei Abgabe des Wassers nach Aichsystem dem controlirenden Wasserwerksbediensteten das aus einem Zapfhahn fliefsende Wasserquantum in Litern pro Minute rasch und genau anzuzeigen.The purpose of the instrument is to control the dispensing of the water according to the Aichsystem Waterworks employees the amount of water flowing from a tap in liters per Minute quickly and accurately.

Der Apparat wird mittelst des konischen Gummiringes A am Auslauf eines Zapfhahnes dicht angesetzt, wodurch das zu messende Wasser gezwungen wird in den Cylinderraum B zu treten, von wo aus dasselbe durch zwei Reihen kleiner, seitlich in der Cylinderwand befindlicher Löcher L L in den Cylindermantel D gelangt und seinen Weg in der Rieh-" tung der Pfeile fortsetzt. Hierbei tritt es von D durch die Löcher EE in den eigentlichen Cylinderraum unter dem Kolben, steigt bis zur Oeffnung M empor und fliefst dann in das als Kolbenstange dienende Rohr über, um bei .Fden Apparat zu verlassen. Das in den Cylinder über dem Kolben eintretende Wasser wird denselben so lange vor sich herschieben, bis eine genügende Anzahl Löcher L L zum Durchflufs des Wassers freigelegt sind. Je nach der Durchflufsmenge in der Zeiteinheit ist der Druck auf den Kolben C, welcher sich mit dem entgegenwirkenden Drucke einer Spiralfeder iS ins Gleichgewicht setzt, verschieden grofs. Einer solcheri Gleichgewichtslage entspricht dann der Ausflufs aus einer gewissen Anzahl von Löchern unter bestimmtem Druck, somit eine bestimmte Wassermenge in der Zeiteinheit. Die Eintheilung auf dem Ausflufsrohr zeigt sofort die Literzahl und Bruchtheile derselben genau an, welche der Zapfhahn pro Minute liefert.The apparatus is tightly attached to the outlet of a tap by means of the conical rubber ring A , which forces the water to be measured to enter the cylinder space B , from where it enters the cylinder jacket D through two rows of small holes LL in the side of the cylinder wall and continues its way in the direction of the arrows. Here it passes from D through the holes EE into the actual cylinder space under the piston, rises to the opening M and then flows into the tube serving as the piston rod, around to. The water entering the cylinder above the piston will push the same in front of it until a sufficient number of holes LL are exposed for the water to flow through. Depending on the flow rate in the unit of time, the pressure on piston C, which is in equilibrium with the counteracting pressure of a spiral spring, of different sizes Then the outflow from a certain number of holes is under a certain pressure, thus a certain amount of water per unit of time. The division on the spout immediately shows the exact number of liters and fractions of it which the tap delivers per minute.

Patent-Anspruch:Patent claim: Ein Wassermesser, bei welchem die Wassermenge aus der Gröfse der Verschiebung eines Kolbens bestimmt wird, der einerseits unter der Wirkung des Wasserdruckes, andererseits unter der einer Feder steht und je nach dem Druck des zuströmenden Wassers mehr oder weniger Ausflufsöffhungen in der Cylinderwand freigiebt.A water meter, in which the amount of water is determined by the displacement of a Piston is determined, on the one hand under the action of water pressure, on the other hand is under a spring and depending on the pressure of the inflowing water more or opens fewer outflow openings in the cylinder wall.
