Abstract:
A hydrostatic leveling system for accurately determining the vertical displacement of horizontal surfaces to aid in leveling large objects, said system comprising:a first container with an internal indicating float and having a base;a second container with an internal indicating float and having a base;a liquid conduit connecting said containers;a body of liquid filling said containers and conduit;a tool for placing said second container base in the same horizontal plane as a horizontal surface of an object to be leveled, said tool including a probe adapted to contact the object being leveled, screw means for raising and lowering said tool and at least two bubble vials disposed at an angle to each other to indicate said second container's orientation with respect to said object, said tool enabling an operator to reproduce said orientation as said tool is moved about the periphery of the object being leveled;an elevator adapted to support and vertically displace the base of said first container to enable the operator to equalize said internal floats; and,means for measuring the amplitude of said vertical displacement.
