KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand vorliegender Erfindung ist eine Rohrzange, deren verschiebbare Backe als gezahntes Rädchen ausgebildet ist, das in eine Verzahnung des Schaftes eingreift und durch eine Feder gegen die feste Maulbacke gezogen wird. Die Erfindung besteht darin,- daß als Feder eine Spiralfeder angewendet ist, die in das Innere der verschiebbaren Backe eingesetzt ist.The subject of the present invention is a pipe wrench, the movable jaw of which is a toothed one Wheel is formed which engages in a toothing of the shaft and through a spring is pulled against the fixed jaw. The invention consists in - that as Spring a coil spring is applied, which is inserted into the interior of the sliding jaw is.
ίο Die Zeichnung veranschaulicht in Fig. ι bis 4 die neue Zange.ίο The drawing illustrates in Fig. ι to 4 the new pliers.
Es ist α der einerseits zu einem Griff, andererseits zu der gezahnten Backe ausgebildete Zangenschaft, der an der Innenseite mit Zähnen h versehen ist, an welchen sich die bewegliche Backe, die ein gezahntes Rädchen bildet, abrollen kann. Zu dem Zwecke ist die Backe g mittels eines Bolzens f in einem den Schaft a umgreifenden Bügel e gelagert. Um nun einen selbsttätigen Schluß des Zangenmaules zu erhalten, ist die Backe g an einem Ende ausgebohrt und in sie eine Spiralfeder m eingelegt, die mit dem einen Ende an dem Bolzen f, mit dem andern an der Backe g befestigt ist.It is α the pincer shaft, which is formed into a handle on the one hand and the toothed jaw on the other, which is provided with teeth h on the inside, on which the movable jaw, which forms a toothed wheel, can roll. For this purpose, the jaw g is mounted by means of a bolt f in a bracket e that encompasses the shaft a. In order to obtain an automatic closure of the pincer jaws, the jaw g is drilled out at one end and a spiral spring m is inserted into it, one end of which is attached to the bolt f and the other to the jaw g.
Das Öffnen dieser Backe bewirkt somit eine Spannung der Feder, die den selbsttätigen Schluß herbeiführt, so daß eine Art Knarrwirkung mit dieser Zange erzielt werden kann.The opening of this jaw thus causes tension in the spring, which causes the self-acting Conclusion brings about, so that a kind of creaking effect can be achieved with these pliers can.
Gemäß Fig. 3 und 4 ist der Schlüsselschaft nicht massiv ausgestaltet, sondern hohl gepreßt, und es wird die feste Backe und die Zahnung h durch ein eingelegtes Winkelstück k aus Stahl gebildet, das durch den Schaft mit Nieten i verbunden ist. Diese Anordnung hat den Vorteil, daß die bewegliche Backe g, die wie vorher in dem Bügel e und dem Bolzen f drehbar gelagert ist, noch besonders in dem Schaft selbst geführt und gegen Kanten gesichert ist. Man kann aber auch den Schaft umgekehrt auspressen, so daß die Höhlung am Rücken liegt, und in diese Höhlung eine Schraubenfeder die durch den Bügel betätigt wird, einfügen.According to FIGS. 3 and 4, the key shank is not solid, but pressed hollow, and the fixed jaw and the teeth h are formed by an inserted angle piece k made of steel, which is connected by the shank with rivets i . This arrangement has the advantage that the movable jaw g, which, as before , is rotatably mounted in the bracket e and the bolt f , is still especially guided in the shaft itself and secured against edges. But you can also press out the shaft the other way around, so that the cavity is on the back, and insert a coil spring actuated by the bracket into this cavity.
