1877.1877. Klasse 47.Class 47. H. HALTAUFDERHEIDE in CASSEL. Schlauchverbindung.H. HALTAUFDERHEIDE in CASSEL. Hose connection. Patentirt im Deutschen Reiche vom 18. Juli 1877 ab.Patented in the German Empire on July 18, 1877. Bei den jetzt im Gebrauch befindlichen Schlauchkupplungen wird das Metall-Endstück, an welchem sich der Konus befindet, in das entsprechende andere Schlauch-Endstück mittelst einer Mutter fest verschraubt, wodurch die wasserdichte Verbindung zwischen beiden Schläuchen hergestellt ist.With the hose couplings now in use, the metal end piece, on which the cone is located, in the middle of the corresponding other hose end piece a nut screwed tightly, creating the watertight connection between the two hoses is made. Das Anziehen der Mutter ist sehr zeitraubend, besonders aber, sobald Sand oder Strafsenschmutz in das Gewinde gekommen ist, kaum möglich.Tightening the nut is very time consuming, especially when it is sand or road dirt got into the thread is hardly possible. Das Reinigen des Gewindes ist sehr umständlich und wird infolge dessen die Mutter nicht angezogen werden können, weshalb sehr oft das Wasser an den Verbindungsstellen durchdringt. Dies ist besonders im Winter von sehr unangenehmen Folgen und beeinträchtigt die Leistungsfähigkeit der Spritze bedeutend.The cleaning of the thread is very cumbersome and as a result the nut does not become can be attracted, which is why the water very often penetrates at the connection points. This has very unpleasant consequences and is impaired, especially in winter Significant efficiency of the syringe. Die neue Schlauchverbindung enthält kein Schraubengewinde und ist daher, falls sich Sand daran gesetzt haben sollte, sofort mit der Hand zu reinigen.The new hose connection does not contain a screw thread and is therefore in case there is sand should have made sure to clean by hand immediately. Der innere Konus α b ist in den äufseren cd eingeschliffen.The inner cone α b is ground into the outer cd . Der Theil α b trägt einen ringsumgehenden Rand R, welcher an den Stellen efg unterbrochen ist, wie aus dem Grundrifs ersichtlich. Die drei so entstandenen Theile R sind nach der Richtung des Pfeiles dünner; z. B. ist Theil R zwischen e g bei g 1 bis 2 mm dicker, als die Höhlung der Knacken. Nach e zu ist R hingegen 3 bis 4 mm schwächer, als bei g, so dafs durch eine Drehung nach der Richtung des Pfeiles die Theile R sich unter die Knacken schieben und so den Konus α b fest gegen den entsprechenden hohlen Konus drücken, wodurch der wasserdichte Verschlufs hergestellt wird.The part α b has an all-round edge R, which is interrupted at the points efg , as can be seen from the outline. The three parts R thus produced are thinner in the direction of the arrow; z. B. Part R is between eg at g 1 to 2 mm thicker than the cavity of the crack. Towards e , however, R is 3 to 4 mm weaker than at g, so that by turning in the direction of the arrow the parts R push themselves under the claws and thus press the cone α b firmly against the corresponding hollow cone, whereby the watertight closure is made. Patent-Anspruch: Eine Schlauchverbindung, bei welcher mittelst konischer Schliffflächen unter Anwendung eines Bajonetverschlusses die dichte Verbindung zweier Schlauchbezw. Rohrenden bewirkt wird, wie durch Zeichnung und Beschreibung dargelegt.Patent claim: A hose connection in which the mean conical ground surfaces using a bayonet lock, the tight connection of two hose and hose connections. Pipe ends is effected as set out by drawing and description.
