Patentirt im Deutschen Reiche vom 18. September 1888 ab.Patented in the German Empire on September 18, 1888.

Der Sicherheitshaken zum Heben von Lasten kann durch eine Falle geschlossen werden, welche durch die angehängte Last fest gegen den Haken herangezogen wird, während ohne Belastung die Falle durch Drehen des Hakens um einen gelenkartig angeordneten Zapfen sich leicht öffnen läfst. Der Haken ist ferner derartig gebaut, dafs er auf einfache Weise von seiner Kette entfernt werden kann.The safety hook for lifting loads can be closed by a trap, which is pulled firmly against the hook by the attached load, while without Load the trap by turning the hook around a pivoted pin opens easily. The hook is also built in such a way that it can be easily removed from its chain can be removed.

Der Haken besteht aus den beiden mittelst Zapfens C gelenkig mit einander verbundenen Theilen A und B, von denen A mit der Kette K verbunden ist, während in den hakenförmig gestalteten Theil B die Last eingehängt werden kann. An einem Arm α des Theiles A ist die zum Verschlüsse des Hakens dienende, um den Zapfen s drehbare Falle F angeordnet, welche mit einem Ansatz g in einen Ausschnitt 0 des um den Zapfen C befindlichen Theiles b des Hakens B einfafst, Fig. 1 und 3. Dieser Theil b hat ferner einen zweiten Ausschnitt ο \ welcher zum Entfernen der Kette K aus A dient. Die Drehung des Hakens B um den Zapfen -C wird durch den Stift £ begrenzt, welcher innerhalb eines in b befindlichen dritten Ausschnittes 02 durch A hindurchgeht und in A mit Gewinde eingeschraubt ist.The hook consists of the two parts A and B articulated to one another by means of pegs C , of which A is connected to the chain K , while the load can be suspended in the hook-shaped part B. On an arm of the part A 1 α is the serving for fasteners of the hook, disposed about the pin's rotatable case F which b with a projection g in a section 0 of the part located around the pin C of the hook B einfafst, Fig. And 3. This part b also has a second section ο \ which serves to remove the chain K from A. The rotation of the hook B around the pin -C is limited by the pin £, which passes through A within a third cutout 0 2 located in b and is screwed into A with a thread.

Um die Falle zu öffnen, wird der Haken B um den Zapfen C aus der Lage der Fig. 1 in diejenige der Fig. 3 gedreht, bis die untere Kante des Ausschnitts o2 gegen den Stift 5 stöfst. Dadurch wird verhindert, dafs der Ansatz g ganz aus den Ausschnitt ο heraustritt. Dies kann erst geschehen, nachdem der Stift S aus A entfernt ist und der Haken B dann weiter aufwärts gedreht wird.To open the trap, the hook B is rotated around the pin C from the position of FIG. 1 to that of FIG. 3 until the lower edge of the cutout o 2 hits the pin 5. This prevents the shoulder g from protruding entirely from the cutout ο. This can only be done after the pin S is removed from A and the hook B is then turned further upwards.

In Fig. 4 und 5 ist der Stift S aus A herausgeschraubt und der Ansatz g aus dem Querschnitt ο entfernt. Wird dann der Haken B in die Lage der Fig. 4 gedreht, so tritt der Ausschnitt 0l unter das unterste Kettenglied K, welches dann in denselben eingeführt und, wie die Fig. 4 und 5 zeigen, bei geeigneter Drehung von B an dem Arm a entlang geführt werden kann, bis dasselbe von der Falle F frei ist.In Fig. 4 and 5, the pin S is unscrewed from A and the shoulder g is removed from the cross section ο. If the hook B is then rotated into the position of FIG. 4, the cutout 0 l occurs under the lowest chain link K, which is then inserted into the same and, as FIGS. 4 and 5 show, with a suitable rotation of B on the arm a can be guided along until it is free from the trap F.

Claims (1)

Patent-Anspruch:Patent claim: Ein Sicherheits-Lasthaken, bestehend aus den mittelst Zapfens C drehbar mit einander verbundenen Theilen A und B, von denen A an einem Arme α die mit dem in eine Zahnlücke ο eingreifenden Zahnansatze g versehene Falle F trägt und mit einem Stift S ausgestattet ist, welcher die für die Oeffnung des Hakens nöthige Drehung der Falle F begrenzt, wobei nach Herausnahme von S auch A gegen B so gedreht werden kann, dafs die Entfernung des Kettengliedes K von dem Haken möglich ist.A safety load hook, consisting of the parts A and B rotatably connected to each other by means of pin C , of which A on an arm α carries the latch F provided with the tooth lugs g engaging in a tooth gap ο and is equipped with a pin S which the rotation of the latch F , which is necessary for the opening of the hook, is limited, whereby after removing S also A can be rotated against B in such a way that the removal of the chain link K from the hook is possible.
