Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Der Zweck vorliegender Erfindung ist, bei Zugmessern für Feuerungs-, Dampfkessel- und Schornsteinanlagen Reibungszustände, wie sie bei anderen dergleichen Messern auftreten, nach Möglichkeit zu vermeiden und den Messer selbst in der Ausführung einfach und wohlfeil zu gestalten. The purpose of the present invention is to draw knives for furnace, steam boiler and Chimney systems friction conditions, as they occur with other similar knives, after Possibility to avoid and to design the knife itself in the execution simple and cheap.

Zu diesem Zwecke wird durch die Stellung eines Körpers im Innern eines durchsichtigen, konisch sich erweiternden Mefsrohres das Ergebnifs der Messung dadurch unmittelbar angezeigt, dafs der Mefskörper in dem bezeichneten Rohre freischwebend untergebracht ist.For this purpose, the position of a body inside a transparent, conically widening measuring tube, the result of the measurement is displayed immediately, that the measuring body is housed floating freely in the designated tube.

Die beiliegende Zeichnung zeigt beispielsweise einen solchen Zugmesser in zwei Ausführungsformen, und zwar Fig. 1 den Querschnitt, Fig. 2 die Ansicht und Fig. 3 den Grundrifs der einen Ausführungsform, Fig. 4 stellt den Querschnitt der zweiten Ausführungsform dar.The accompanying drawing shows, for example, such a draft knife in two embodiments, namely Fig. 1 the cross section, Fig. 2 shows the view and Fig. 3 shows the outline of the one embodiment, Fig. 4 shows the Cross section of the second embodiment.

Ein durchsichtiges und in seinem Innern nach oben erweitertes, z. B. aus Glas hergestelltes Rohr α ist in eine Fassung eines in die bezeichneten Anlagen einstehenden Rohres c eingeschlossen und mit einer Scala versehen. In dem Rohre α ist der Körper d derart freischwebend untergebracht, dais er den engsten Querschnitt des Rohres ganz oder annähernd ausfüllt.A transparent and in its interior expanded upwards, z. B. made of glass tube α is enclosed in a socket of a standing in the designated systems tube c and provided with a scale. In the tube α , the body d is accommodated in a freely floating manner in such a way that it completely or approximately fills the narrowest cross section of the tube.

Der in der bezeichneten Anlage herrschende Zug und die in dem Rohre α dadurch hergestellte Saugwirkung bewirkt das Steigen des Körpers in dem Rohre α so weit, bis ein genügend grofser Durchgangsquerschnitt neben dem Körper d im Rohre α freibleibt. Es wird dadurch ein Mafsstab für die jeweilige Zugstärke geschaffen, welche an einer Scala abzulesen ist.The tension prevailing in the designated system and the suction effect thereby produced in the tube α causes the body to rise in the tube α until a sufficiently large passage cross-section remains free next to the body d in the tube α . This creates a yardstick for the respective tensile strength, which can be read on a scale.

Bemerkt sei noch, dafs in den meisten Fällen die senkrechte Stellung des konischen Rohres nach Fig. 1 und 2 in Anwendung kommen wird, doch könnte man demselben auch eine geneigte Lage geben.It should also be noted that in most cases the vertical position of the conical tube 1 and 2 will come into use, but you could also give the same an inclined position.
