ABSTRACT:
The invention disclosed herein includes a method and apparatus for latching a temporary guide base to a permanent guide base as the permanent guide base is raised, whereby the two guide bases may be retrieved simultaneously. The apparatus includes a socket means in each guideline of the temporary guide base and a latch means in the base of each guidepost of the temporary guide base. When the permanent guide base is lowered, the latch means passes over the socket means. When the permanent guide base is raised, however, the latch means engages the socket means and the temporary guide base is raised.
