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 13):
An apparatus for extracting a paver from a preset position, comprising:\n (a) one or more opposing pairs of lifting plates, each said plate having (i) a body portion containing at least one lifting aid insertion opening at one end of the body, and (ii) at an opposing end of the plate, a blade portion having substantially concave tabs with tab edges formed along a pair of slots terminating in one or more stress relief openings between the body and the blade, whereby upon (1) wedging a first blade between the subject paver and a first adjacent paver and wedging a second blade at an opposing end of the paver and a second adjacent paver, substantially compressing the tabs storing spring energy in the blades, and (2) pushing the tab edges below a 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; and (b) one or more lifting aids for joining one or more opposing pairs of lifting plates.
