KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei der Einrichtung der alten Steinzange, die zum Heben großer Steine, sogenannter Findlinge, aus Wasserläufen dient, ist der Fehler vorhanden, daß die Zangenklauen aus doppelarmigen Hebeln bestehen, die auf Biegung in Anspruch genommen werden; infolgedessen wird das Gewicht der Steinzange groß, so daß das Arbeiten damit sehr umständlich ist.When setting up the old stone tongs, which are used to lift large stones, so-called Erratic boulders, used from watercourses, the fault is present that the pincer claws from double-armed levers that are used on bending; Consequently the weight of the stone tongs is great, so that working with it is very cumbersome is.
ίο Bei der Steinzange der Erfindung bestehen die Zangenklauen nicht aus Doppelhebeln und werden im wesentlichen nur auf Zug in Anspruch genommen. Die neue Steinzange wird deshalb wesentlich leichter als die alte Steinzange und ihre Handhabung dadurch sehr erleichtert.ίο In the stone tongs of the invention exist the pincer claws do not consist of double levers and are essentially only used to train taken. The new stone tongs are therefore much lighter than the old stone tongs and their handling is made much easier as a result.
Die neue Steinzange ist in den Fig. 1 und 2 abgebildet. An einen Ring c greifen zwei oder mehrere Klauen α mittels der Bolzen b an.The new stone tongs are shown in FIGS. Two or more claws α attack a ring c by means of the bolts b .
An den Klauen α sind die abnehmbaren Handhaben η befestigt, durch welche die Steinzange gehandhabt wird, um sie an den zu hebenden Stein S anzusetzen. Nachdem das Ansetzen der Steinzange zweckentsprechend erfolgt ist, wird die Schraubenspindel d, die in dem Ring c angebracht ist, angezogen, wobei sie sich mit ihrer Spitze gegen die Oberfläche des Steines S anlegt und nunmehr die Klauen α so an den Stein anpreßt, daß die Steinzange mit ihm fest verbunden ist. Um die Schraubenspindel d oberhalb des Wasserspiegels W zugänglich zu machen, kann es erwünscht sein, eine ansetzbare Verlängerung h anzuordnen.The removable handles η , by means of which the stone tongs are manipulated, in order to attach them to the stone S to be lifted are attached to the claws α. After the application of the stone tongs is done appropriately, the screw spindle d, which is mounted in the ring c , is tightened, where it rests with its tip against the surface of the stone S and now the claws α presses against the stone that the Stone tongs is firmly attached to it. In order to make the screw spindle d accessible above the water level W , it may be desirable to arrange an attachable extension h.
Nachdem die Steinzange in der oben angegebenen Weise mit dem zu hebenden Stein fest verbunden ist, können die Handhaben η entfernt werden, damit sie bei der Arbeit des Hebens des Steines nicht hinderlich sind.After the stone tongs are firmly connected to the stone to be lifted in the manner indicated above, the handles η can be removed so that they are not a hindrance to the work of lifting the stone.
Das Heben des Steines wird mittels irgendeiner Hebevorrichtung, die an Kette g angreift, besorgt.The stone is lifted by means of any lifting device that engages chain g.
