Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Fig. ι stellt die bekannte Construction schematisch mit mehr geöffneter und Fig. 2 dieselbe Construction mit weniger geöffneter Klaue dar. Es ist ersichtlich, dafs die Backen α der Klauen χ nicht parallel bleiben. Dies ist für manche Anwendungen unbequem.Fig. 1 shows the known construction schematically with a more open claw and Fig. 2 the same construction with a less open claw. It can be seen that the jaws α of the claws χ do not remain parallel. This is inconvenient for some applications.

Um diese Unbequemlichkeit zu vermeiden, sind, wie in Fig. 3 und 4 dargestellt ist, die Klauen bei χ nochmals mit einem Gelenk versehen und die Backenenden über den Gelenkpunkt nach der anderen Seite hin verlängert, so dafs der hinzugefügte Theil α χ d einen zweiarmigen Hebel bildet.In order to avoid this inconvenience, as shown in Fig. 3 and 4, the claws at χ are again provided with a hinge and the jaw ends are lengthened beyond the hinge point to the other side, so that the added part α χ d has two arms Lever forms.

Beim Anheben der Last legt sich der Arm χ d fest gegen das Scharnier c · und, wie der Vergleich zwischen Fig. 3 und 4 zeigt, bleiben nunmehr die Backen α bei mehr oder weniger geöffneter Klaue stets parallel, wenn der Arm b χ gleiche Länge mit dem Arm b c hat. Es kann auch der Arm, wie in Fig. 3' punktirt angegeben ist, sich gegen einen Stift j/· stützen, wodurch derselbe Zweck erzielt wird.When lifting the load, the arm χ d lies firmly against the hinge c · and, as the comparison between FIGS. 3 and 4 shows, the jaws α now always remain parallel when the claw is more or less open if the arm b χ is the same length with arm bc has. The arm, as indicated in dotted lines in Fig. 3 ', can also support itself against a pin, whereby the same purpose is achieved.
