Abstract:
A hand tool for extracting bolts comprising:a stationary plate having a front surface and a rear surface and formed such that a plurality of transverse apertures exist which run from said front surface to said rear surface; a plurality of rods having two ends and attached to said rear surface of said stationary plate; a sliding plate existing in a parallel plane to said stationary plate and having a front surface and a rear surface and formed such that a plurality of transverse apertures exist which run from said front surface to said rear surface, at least one said aperture being threaded, such that said opposite end of said rods pass through said non-threaded apertures at said front surface and extend beyond said rear surface in a direction perpendicular to said sliding plate; a plurality of cylindrical rod housings having two ends and formed such that an aperture exists along the longitudinal axis and extends along the entire length of said rod housing, said rod housings connected on said end to said sliding plate at said non-threaded transverse apertures and passing through said stationary plate at said transverse apertures and extending on said opposite end beyond said front surface of said stationary plate in a direction perpendicular to said stationary plate; a plurality of bolt housings having two ends and formed such that an aperture exists along the longitudinal axis and extends along the entire length of said bolt housing, said bolt housings connected on said end to said front surface of said stationary plate and extending on said opposite end away from said front surface of said stationary plate in a direction perpendicular to said stationary plate; a jack bolt having a rod, a rod end, and a bolt end and placed such that said rod passes through said threaded transverse aperture in said sliding plate and said rod end contacts said stationary plate and said bolt end extends away from said rear surface of said sliding plate in a direction perpendicular to said sliding plate; a plurality of cylindrical extractor rods having a main body and two ends and of such diameter that said rods pass through said cylindrical rod housings and are attached to said rear surface of said sliding plate by a connector.
