PATENTAMT.PATENT OFFICE.
Diese Gasrohrzange soll als Ersatz für die seither gebräuchlichen Zangen dienen, welche entweder nur für eine bestimmte Gasrohrsorte anzuwenden sind oder wie die sogenannten Universalgasrohrzangen erst für jede Dicke besonders eingestellt werden müssen.This gas pipe wrench is intended to serve as a replacement for the pliers that have been in use since then, which either only to be used for a certain type of gas pipe or like the so-called Universal gas pipe wrenches first have to be specially set for each thickness.
Indem sich um den Zapfen A die beiden Greifbacken B und C öffnen oder schliefsen, greift die Zange Rohrdicken von 15 bis 43 mm beim Anholen sofort fest an. Die beiden gezahnten Seiten der unteren Greifbacke B stehen in einem bestimmten spitzen Winkel zu einander, damit durch den Druck des eigenartig geformten Maules C das Rohr in diesen Winkel hineingedrückt wird.As the two gripping jaws B and C open or close around pin A , the pliers grasp pipes with a thickness of 15 to 43 mm immediately when they are picked up. The two toothed sides of the lower gripping jaw B are at a certain acute angle to each other, so that the pipe is pressed into this angle by the pressure of the peculiarly shaped mouth C.
Um zur Handhabung der Zange nur eine Hand zu brauchen, ist die Feder D angeordnet, welche beide Maulhälften zusammendrückt, das Oeffnen bis auf den gröfsten Durchmesser jedoch leicht gestattet. Hierdurch ist erreicht, dafs die Zange ohne äufsere Hülfe fest auf jedem Rohr sitzen bleibt und ähnlich wie bei einer Bohrknarre beim Gebrauch sofort immer wieder nach einer vollzogenen Drehung in der neuen Stellung fest angreift.In order to only need one hand to handle the pliers, the spring D is arranged, which presses both halves of the mouth together, but allows easy opening up to the largest diameter. In this way it is achieved that the pliers remain firmly seated on each pipe without external help and, similar to a ratchet, grabs firmly in the new position immediately after a complete rotation.
