Abstract
A bar type jack having first and second pipes of suitable length each threaded at at least one end thereof. The first pipe is substantially longer than the second pipe and has a first jaw member slidable therealong for quick positioning and lockable at any position. A mounting bracket having a threaded bore extending from one face thereof to and through an opposite face interconnects the first and second pipes. A second jaw member is slidable along the second pipe and movable by rotating a threaded rod that extends through an additional threaded bore in the bracket. A handle is swingably connected to one end of the threaded rod for use in rotating the rod. Removable jaw attachments are provided and so shaped as to permit jacking one member relative to another when the members to be jacked apart are located closely adjacent one another.
