Description

Vorrichtung zum erschütterungsfreien Belasten empfindlicher, hauptsächlich für Materialprüfungen dienender Waagen mittels Zufuhr von Flüssigkeit. Die Erfindung betrifft eine Vorrichtung zur allmählichen stoßfreien. Belastung und Entlastung von Waagschalen für empfindlichste Gewichtsmessungen, vorzugsweise in Verbindung mit Materialprüfungsapparaten mittels Zufuhr von Flüssigkeit.Device for vibration-free loading more sensitive, mainly Scales used for material testing by means of a supply of liquid. The invention relates to a device for gradual bumpless. Burden and relief of weighing pans for the most sensitive weight measurements, preferably in conjunction with material testing apparatus by supplying liquid.

Das Wesen. der Erfindung besteht in der besonderen Ausgestaltung von kommunizierenden Röhren in Verbindung mit einem Flüssigkeitssaugheber im Anschluß an eine zylindrische Gefäßwaagschale, wobei unter Zuhilfenahme eines Verdrängers oder durch senkrechte Bewegung eines kommunizierenden Röhrenschenkels die belastende Flüssigkeit stetig, erschütterungs- und stoßfrei in das zylindrisch ausgebildete Belastungsgefäß der Waage gefördert wird.The essence. the invention consists in the particular embodiment of communicating tubes in connection with a liquid siphon in the connection to a cylindrical weighing pan, with the aid of a displacer or through vertical movement of a communicating tube limb the stressful one Fluid steadily, vibration and shock-free in the cylindrically designed Loading vessel of the balance is promoted.

Diese Kombination gestattet gleichzeitig eine unmittelbare Nebeneinanderstellung der senkrecht angeordneten Bewegungsskalen der Last- und Kraftwaage, welch letztere kinematographische Aufnahmen der Wiegemomente auf nur einen Film ermöglichen. .This combination also allows a direct juxtaposition the vertically arranged movement scales of the load and force scales, which latter enable cinematographic recordings of the weighing moments on just one film. .

Abb. r stellt den Schnitt A-8 und Abb. 2 den Grundriß des Erfindungsgegenstandes dar.Fig.r represents section A-8 and Fig. 2 the floor plan of the subject matter of the invention.

Zwecks Herbeiführung einer erschütterungs-und stoßfreien stetigen, Belastung von Waagschalen, vorzugsweise für Materialprüfungen, ist erfindungsgemäß der bekannte Kommunikatnonsrohrschenkel a mit eitiem zylindrischen, ' Saughebertauschschenkel b in der Weise versehen, daß die Ausmündung des letzteren durch die Belastungsflüssigkeit des zylindrisch ausgebildeten Gefäßes c der Waage d stets abgeschlossen ist, während die Belastung der- Waagschale c durch Anhebung des Kommunikationsrohres e, wobei der Schlauch f die Bewegung gewährleistet, oder durch Senkung des Verdrängers g in letzteres, e, erfolgt.In order to achieve a vibration and shock-free continuous, Loading of weighing pans, preferably for material testing, is according to the invention the well-known communication tube leg a with a cylindrical 'suction siphon exchange leg b provided in such a way that the outlet of the latter through the loading fluid of the cylindrically shaped vessel c of the balance d is always closed while the load on the weighing pan c by raising the communication tube e, where the hose f ensures movement, or by lowering the displacer g in the latter, e, takes place.

Zur richtigen Feststellung des Gewichtes der Belastungsflüssigkeit bei den stets voneinander abweichenden Temperaturen ist ein bekanntes Thermometer lt in das Kommunikationsrohr a eingeschaltet. Die senkrechten Bewegungen der Kommunikatitehbürette e oder des Verdrängers g gibt der Zeiger i auf der Skala k an.In order to correctly determine the weight of the loading liquid at the temperatures that always differ from one another, a known thermometer is switched into the communication tube a. The vertical movements of the communication burette e or the displacer g are indicated by the pointer i on the scale k.

Die Gesamtanordnung der Erfindung gestattet ferner eine unmittelbare Nebeneinanderlegung der Belastungsskala k mit der Lastskala l des zu wiegenden oder auf Dehnung zu untersuchenden Gegenstandes bei stetiger Hand- oder Motorbetätigung der Belastung, so daß eine kinematographische Aufnahme der Last- und Kraftmomente, auf nur einen Film erfolgen kann.The overall arrangement of the invention also allows for immediate Juxtaposition of the load scale k with the load scale l of the or to be weighed object to be examined for elongation with constant manual or motor operation the load, so that a cinematographic recording of the load and force moments, can be done on just one film.
