  • Patent number: 5212859
    Abstract: A pliers for removing and manipulating a snap ring and like ring devices, wherein the pliers is defined by handles pivotally connected to each other. The handles comprise a pair of integrally formed jaw members that are provided with a positive engaging socket member formed on each of the respective free end portions of the jaw members. The socket members include a convergent socket arranged to lockingly receive the respective open free ends of the snap ring. A pivoting member is positioned intermediate the handles and jaw members with a biasing spring mounted between the oppositely disposed jaw members forwardly of the pivot member, whereby the jaw members are biased in an open position so as to forcibly engage each of the socket members with the respective open ends of the snap ring, thereby preventing the snap ring from being inadvertently removed or disengaged from the convergent sockets.
