Description
Der Zweck dieser Erfindung ist eine Verbesserung an Manometern, welche darin besteht, dafs wir die Bewegung zweier, in einem Gehäuse gelagerter Federn auf zwei concentrisch zueinander stehende Zeiger so übertragen, dafs beide Zeiger bei eintretender Beanspruchung der Federn sich gleichmäfsig nach einer Richtung bewegen, also sich decken und nur einer Scala bedürfen, und die Beobachtung derselben insofern vereinfachen, als nur eine Zeigerspitze beobachtet zu werden braucht.The purpose of this invention is to improve pressure gauges, which consists in: that we see the movement of two springs mounted in a housing on two concentric Pointers that are in relation to one another are transferred in such a way that both pointers are subjected to stress the feathers move uniformly in one direction, that is, they coincide and require only one scale, and observation simplify the same insofar as only one pointer tip needs to be observed.
Wir basiren unsere Construction auf die bei Control-Manometern übliche Annahme, dafs das Manometer richtig ist, so lange die Indicationen beider Zeiger übereinstimmen, und erreichen durch unsere Construction den Vortheil, nur einer Scala zu bedürfen und aufserdem nur quasi einen Zeiger beobachten zu müssen. Bei der kleinsten eintretenden Differenz werden die beiden Zeiger voneinander abweichen und eine sehr in die Augen fallende Stellung zueinander einnehmen. Die Spitze des unteren der beiden Zeiger ist mit einer kleinen Scala oder mit einem einfachen Strich versehen, wodurch die etwa zulässige Abweichung wahrgenommen werden kann.We base our construction on the common assumption of control pressure gauges that this Manometer is correct as long as the indications of both pointers match, and reach through our construction the advantage of requiring only one scale and besides only quasi having to watch a pointer. With the smallest occurring difference, the two pointers differ from each other and a very conspicuous position to each other take in. The tip of the lower of the two hands is marked with a small scale or with provided with a single line, whereby the approximately permissible deviation can be perceived can.
Die Zeichnung veranschaulicht den Mechanismus der Uebertragung der Bewegung der Federn auf die Zeiger in der Weise, dafs die Axe des einen Zeigers, analog der Einrichtung an den Zeigern einer gewöhnlichen Uhr, in der durchbohrten Welle des anderen Zeigers gelagert ist; ebensogut aber kann man auch anstatt die eine Welle zu durchbohren, einen geraden und einen gekröpften Zeiger anwenden.The drawing illustrates the mechanism of transmission of the movement of the Springs on the pointer in such a way that the axis of one pointer is analogous to the device on the hands of an ordinary watch, mounted in the pierced shaft of the other hand is; but you can just as well instead of piercing one shaft, a straight and use a cranked pointer.
Patent-Anspruch: Die Uebertragung der Bewegung zweier oder mehrerer in einem Gehäuse gelagerter Manometerfedern in der Weise, dafs die zu denselben gehörigen, voneinander unabhängigen Zeiger ihre Drehpunkte in einem gemeinschaftlichen Punkt haben, also nur einer Scala bedürfen. Einer der Zeiger besitzt eine kleine Scala, auf der die zulässige Toleranz angegeben sein kann.Patent claim: The transmission of the movement of two or more in one housing mounted manometer springs in such a way that those belonging to them are separated from each other independent pointer their pivot points in one have a common point, i.e. only need one scale. One of the hands has one small scale on which the permissible tolerance can be indicated.
