Abstract
Abstract Pulling apparatus particularly adapted for use under emergency conditions for applying a heavy pulling force to the body of an automobile for opening a closed door or other heavy work. The apparatus may be collapsed so as to permit its storage in a small space as, for example, the trunk of an automobile, and may be quickly erected at the site of an automobile accident for immediate operation.
