Abstract:
A device for removing rotating head rubbers from drill pipe comprising a base member, vertical shaft, lower pipe attachment bracket, left arm, right arm, diagonal shaft and upper pipe attachment member. Proximal ends of the left and right arms are welded to a top end of the vertical shaft, and the left and right arms lie in the same horizontal plane. Proximal ends of the left and right arms are welded together and distal ends of the left and right arms are separated so that the arms form a V-shaped fork. The diagonal shaft is welded to the top end of the vertical shaft at an upward angle of approximately 45 degrees. The upper pipe attachment member is removably inserted into a distal end of the diagonal shaft.
