Abstract

PURPOSE: To draw up a cylindrical body simply by transmitting a drawing-up force for a block during the lifting period of the weight through a slip and a wedge block bu utilizing the weight for boring.
CONSTITUTION: When a wire rope 2 is moved vertically, a clamp 9 for drawing up, attached to the weight 1, is striken from below when it is sent up, the force is transmitted through the block 6 and a slip 3 to the cylindrical body 4, and the cylindrical body 4 is drawn up against a frictional resistance. The cylindrical body 4 repeats its ascending and stopping movements by the repeated ascending and descending actions of the weight 1 and then goes up gradually. When it goes up to a given position, the block 6 is striken down by a clamp 21, and the slip 3 is removed from the cylindrical body 1.
