The guide means defining a first gripping surface and the operator means defines a second gripping surface. The two surfaces are in a facing spaced relationship. Between these two surfaces a restricting means is disposed. The restricting means is springingly connected to an operating arm which influences its position. The extremities of the gripping surfaces are at different distances from one another, which causes a rope of appropriate size to become jammed between a gripping surface and the restricting means, depending upon the position of the restricting means.Field of SearchWith mechanism for retarding or preventing cable movement or element rotationHaving portion of block repositionable for insertion or removal of cable or for exposure of elements With block for element having stationary portion adapted to coact with element to grip cable With portable block for element and hand manipulated means for removably fastening block to support or load With means for affixing element to support base and allowing relative movement therebetween Including pivotal, rotational, or swivel connection | |
