1880.1880. Klasse 47.Class 47. HERMANN KGTTGEN in BERGISCH GLADBACH. Schraubensicherung.HERMANN KGTTGEN in BERGISCH GLADBACH. Screw locking. Patentirt im Deutschen Reiche vom 25. Februar 1880 ab.Patented in the German Empire on February 25, 1880. Die. Schraubensicherung besteht aus einer dünnen Platte A, aus Metallblech oder Tempergufs, welche in der Mitte mit einem Loch für den Schraubenbolzen versehen ist und art ihrem Umfang eine Anzahl von Lappen a, ähnlich den Zähnen eines Zahnrades, hat. Auf der unteren Fläche hat die Platte eine kleine Nase b. The. Screw locking consists of a thin plate A, made of sheet metal or malleable cast iron, which is provided with a hole for the screw bolt in the middle and has a number of tabs a, similar to the teeth of a gear wheel, on its circumference. The plate has a small nose on the lower surface b. Die Platte wird unter die Schraubenmutter gelegt, so dafs die Nase in eine entsprechende Vertiefung der Unterlage eingreift und hierdurch an der Drehung verhindert ist. Wenn sodann einer der Lappen α in die Höhe gebogen und fest an eine der Seitenflächen der Mutter angedrückt worden ist, Fig. 1 und 3, so wird dadurch die Mutter an der Drehung verhindert. The plate is placed under the screw nut so that the nose engages in a corresponding recess in the base and is thus prevented from rotating. If one of the tabs α has then been bent upwards and pressed firmly against one of the side surfaces of the nut, FIGS. 1 and 3, the nut is prevented from rotating. Bei der gröfseren Anzahl der kleinen Lappen a, deren für eine 26 mm starke Schraube, wie sie die Zeichnung zeigt, ohne Nachtheil etwa 12 Stück vorhanden sein können, bedarf es für eine sechskantige Mutter höchstens yi2 . ye = y72 Umdrehung, um die Mutter feststellen zu können.With the larger number of small lobes a, of which about 12 pieces can be present for a 26 mm thick screw, as shown in the drawing, without disadvantage, a hexagonal nut requires at most y i2 . y e = y 72 turns to be able to lock the nut. Die grofse Zähl der Lappen erlaubt aber auch eine öftere Lösung und Feststellung der Mutter, da die Sicherheitsplatte so lange brauchbar ist, als noch Lappen vorhanden sind, das Abbrechen einzelner Lappen durch das Hin- und Herbiegen beim Lösen und Feststellen also die Platte nicht sofort unbrauchbar macht.The large number of lobes, however, also allows for a more frequent solution and determination of the Mother, since the safety plate can be used as long as there are still rags, that Breaking off individual flaps by bending back and forth when loosening and locking does not immediately render the plate unusable. Wenn die Sicherheitsplatte aus Tempergufs hergestellt wird, so kann die Nase angegossen werden. Bei Herstellung der Platte aus Blech ist es zweckmäfsig, die Nase durch Einpressen von der oberen Seite zu bilden.If the safety plate is made of malleable cast iron, the nose can be cast on will. If the plate is made from sheet metal, it is useful to press-fit the nose from the top to form. Paten τ-Anspruch:Sponsorship τ claim: Eine Schraubensicherung, bestehend aus einer dünnen Metallplatte mit einer Nase auf der unteren Seite und einer gröfseren Anzahl von Lappen am Umfang, von welchen letzteren ein Lappen zur Feststellung der Schraubenmutter in die Höhe gebogen und an eine Seitenfläche der Mutter angedrückt wird, wie beschrieben.A threadlocker consisting of a thin metal plate with a tab on the lower side and a greater number of lobes around the circumference, one of which is the latter Tabs to hold the nut in place are bent upwards and attached to one side the nut is pressed as described.
