Abstract

10,200. Nunn, F. W., and Hanks, T. April 30. Rope grips for securing a pit cage to the guide-ropes in the event of the hoisting-cable breaking comprise a two - part casing b<1>, b<2> surrounding the rope and provided internally with a conical surface. A two-part tube c, cylindrical internally to fit around the rope a and conical externally, is arranged within the casing b<1>, b<2> and is provided with slots to receive a ring of balls g. Transverse pins d<1>, d2 projecting through slots e', e<2> in the casing are connected by cords or levers to the hoisting- cable. When the tube c is raised by the springs f, the balls wedge themselves between the rope and the conical face of the casing.
