Abstract:
An apparatus for extracting a paver stone, and the like from a preset position, including a pair of lifting plates having a body containing one or more lifting aid insertion openings at one end, and at an opposing end, a blade portion having substantially concave tabs with tab edges formed along a pair of slots terminating in one or more of stress relief openings between the body and the blade, wedging a first blade between the paver and a first adjacent paver and wedging a second blade at an opposing end of a paver and a second adjacent paver, substantially compressing the tabs storing spring energy in the blades, pushing the tab edges below the bottom plane of the paver, releasing the stored spring energy thereby substantially decompressing and re-forming the tabs such that the tab edges contact and engage the underside of the paver to be extracted.

Claim (Index 15):
The method of  claim 14 , including the steps of: (a) wedging two or more lifting plates between a paver and one or more adjacent pavers, each lifting plate having (i) a body portion, and (ii) a blade portion having substantially concave tabs and tab edges formed along a pair of slots and stress relief openings between the body and the blade, (b) compressing the tabs and the tab edges of the lifting plates thereby storing spring energy in the blades, (c) pushing the tab edges of the lifting plates past the bottom plane of the subject paver thereby releasing the stored spring energy thereby substantially decompressing and re-forming the tabs, (d) contacting and engaging the tab edges of the lifting plates with the underside of the paver, (e) inserting two or more lifting aids through one or more insertion openings of two or more lifting plates, (f) aligning said insertion openings with one or more notches joining, attaching, affixing or securing the two or more lifting plates using the two or more lifting aids, (g) applying an upward force on the lifting aids and transferring such upward force to the lifting plates, (h) extracting the paver, wherein optionally, coincident with an upward force applied to a lifting system, a downward force is applied using one of a soft-faced hammer or mallet, to one or more of the adjacent pavers to counteract stiction.
