  • Patent number: 4771500
    Abstract: A plumbers snake having a weighted member and a connected jointed end portion which is connected to the leading end of an elongated flexible member for facilitating the threading of the elongated member through a length of pipe for clearing and/or removing an obstruction in such pipe. The weighted end and jointed members are arranged to facilitate negotiating sharp bends formed in such pipes by the jointed members being hingedly connected for movement in different planes, and which jointed portion is rendered either flexible for passing through bends or rigid to form a ram rod upon meeting an obstruction. This is attained by a jointed end portion formed of a plurality of connected links having complementary ball and socket interconnecting portions whereby the jointed end portion is rendered either flexible or rigid depending upon the form and/or nature of the obstruction encountered.
