PATENTAMT.PATENT OFFICE.
Die Erfindung besteht in einem Schraubenschlüssel, der durch auswechselbare Backen mit Zahntrieb verstellbar ist.The invention consists in a wrench that has interchangeable jaws Gear drive is adjustable.
Fig. ι zeigt den Schlüssel in Seitenansicht,Fig. Ι shows the key in side view,
Fig. 2 denselben von unten gesehen,.Fig. 2 the same seen from below.
Fig. 3 einen Backen für eine Mutter von oben gesehen,3 shows a jaw for a nut seen from above,
Fig. 4 Seitenansicht dieses Backens,Fig. 4 side view of this baking,
Fig. 5 untere Ansicht desselben,Fig. 5 bottom view of the same,
Fig. 6 Querschnitt a-b der Fig. 3.FIG. 6 cross-section from FIG. 3.
Fig. 7 zeigt den Schlüssel beim Anziehen einer Mutter.Fig. 7 shows the key tightening a nut.
Der Schlüssel besteht aus zwei Zahnkränzen c und d (Fig. 1 und 2), die durch den Hebel e verbunden sind. Zu jedem Zahnkranz passen drei Backen, die für drei Muttern von verschiedenen Durchmessern vorgerichtet sind. Mit einem Schlüssel kann man also sechs Muttern von verschiedenen Gröfsen anziehen.The key consists of two sprockets c and d (Fig. 1 and 2), which are connected by the lever e . Each sprocket fits three jaws, which are prepared for three nuts of different diameters. So you can tighten six nuts of different sizes with one wrench.
Die Backen bestehen aus dem Zahnkranz f (Fig. 3, 4, 6 und 7), der mit der Hülse g (Fig. 3, 4 und 6) verbunden ist. Diese Hülse g ist innen mit Flächen h (Fig. 5) versehen, die sich der Mutter, die angezogen werden soll, anpassen. Der etwas vorspringende Rand i (Fig. 6) der Hülse hat den Zweck, zu verhindern , dafs die Hülse über die Mutter hinweggleitet. The jaws consist of the ring gear f (Fig. 3, 4, 6 and 7), which is connected to the sleeve g (Fig. 3, 4 and 6). This sleeve g is provided on the inside with surfaces h (FIG. 5) which adapt to the nut that is to be tightened. The slightly protruding edge i (Fig. 6) of the sleeve has the purpose of preventing the sleeve from sliding over the nut.
Soll eine Mutter angezogen werden, so hat man den Backen zu wählen, der für diese Mutter pafst. Man schiebt denselben über die Mutter und legt den zu diesem Backen passenden Zahnkranz des Schlüssels auf den Zahnkranz des Backens, so dafs die Zähne in einander greifen, wie Fig. 7 zeigt.If a nut is to be tightened, one has to choose the jaw that is suitable for this Mother paws. You push it over the mother and place the one that fits this cheek The ring gear of the key on the ring gear of the jaw so that the teeth fit together grab, as Fig. 7 shows.
Die Vorzüge dieses Schlüssels anderen Systemen gegenüber bestehen darin, dafs man, wenn beim Anziehen wenig Platz vorhanden ist, nicht nöfhig hat, von Fläche zu Fläche auszuholen, sondern das Anziehen auf einem kleinen Raum, von Zahn zu Zahn, bewerkstelligen kann.The advantages of this key over other systems are that if there is little space to put on, not able to move from surface to surface but rather pulling them on in a small space, from tooth to tooth can.
Die Backenstärke kann sehr schwach construirt werden, weil nicht zwei Flächen, sondern die sämmtlichen Flächen der Mutter gefafst werden. Dies ist vorteilhaft, wenn sich Hindernisse in unmittelbarer Nähe der Mutter befinden.The thickness of the jaws can be constructed very weakly because it is not two surfaces, but rather all the surfaces of the mother are grasped. This is beneficial when looking There are obstacles in the immediate vicinity of the mother.
Ein Abrutschen des Schlüssels beim Anziehen kann nicht stattfinden, weil die ganze Mutter umspannt wird.Slipping of the key when tightening cannot take place because the whole Mother is spanned.
Schlüssel wie Backen können aus schmiedbarem Gufs hergestellt werden, haben ein geringes Gewicht und bedürfen keiner weiteren Bearbeitung.Keys like jaws can be made from malleable cast iron, have a low weight and do not require any further processing.
