Abstract
Disclosed is an elevator for handling pipe with enlarged ends by gripping the end of the pipe with the enlargement between two hinged arm pieces. In the specific embodiment shown, one arm piece fits into the end of the pipe with enlarged end in the form of a collar, and cooperates with a C-shaped receptacle which is fixed to the end of the other arm piece, and which fits around the pipe and catches the pipe collar to prevent the pipe from separating from the first arm inserted into the pipe end. A spring-actuated lock prevents the arms from opening and releasing the pipe.
