A tool for levering concrete mesh wire, and the like, comprising: (a) an elongated straight lever member formed of hollow metal tubing and having an outer lever end and an inner lift end, said lift end having rigidly secured thereto an outwardly extending concave metal point member adapted to engage strands of wire mesh and the like; and (b) a lever support structure slidably and adjustably mounting said lever member intermediate the said lever and lift ends thereof, said support structure comprising: (i) a central hollow tubular metal leg member extending outwardly below and in perpendicular relation to the longitudinal axis of said lever member and having at the upper end of said leg member a collar integrally secured thereto and slidably fitted on said lever member; (ii) a pair of hollow tubular metal strut members having lower ends rigidly fixed to opposed lower surfaces of said central leg member and extending outwardly and upwardly therefrom to respective collars secured thereto and slidably fitted on said lever member on opposite sides of said central leg member collar; (iii) an auxiliary telescoping hollow tubular leg member slidably fitted within said central leg member and providing means for extending the length thereof, said auxiliary leg member having a hollow tubular metal ground support crossbar secured to the lower end thereof in an inverted T configuration and being of a length selected to span the mesh of reinforcement wire with which said tool is used; (iv) locking means for locking said auxiliary leg member in a selected position on said central leg member to position the pivot point of said lever at a selected distance above the level of ground support; and (v) means on said pivotal support structure for locking such structure to said lever member to locate the position of said pivot point along the length of said lever.

A tool for levering concrete mesh wire, and the like, comprising: (a) an elongated straight lever member formed of hollow metal tubing and having an outer lever end and an inner lift end, said lift end having rigidly secured thereto an outwardly extending concave metal point member adapted to engage strands of wire mesh and the like; and (b) a lever support structure slidably and adjustably mounting said lever member intermediate the said lever and lift ends thereof, said support structure comprising: (i) a central hollow tubular metal leg member extending outwardly below and in perpendicular relation to the longitudinal axis of said lever member and having at the upper end of said leg member a collar integrally secured thereto and slidably fitted on said lever member; (ii) a pair of hollow tubular metal strut members having lower ends rigidly fixed to opposed lower surfaces of said central leg member and extending outwardly and upwardly therefrom to respective collars secured thereto and slidably fitted on said lever member on opposite sides of said central leg member collar; (iii) an auxiliary telescoping hollow tubular leg member slidably fitted within said central leg member and providing means for extending the length thereof, said auxiliary leg member having a hollow tubular metal ground support crossbar secured to the lower end thereof in an inverted T configuration and being of a length selected to span the mesh of reinforcement wire with which said tool is used; (iv) locking means for locking said auxiliary leg member in a selected position on said central leg member to position the pivot point of said lever at a selected distance above the level of ground support; and (v) means on said pivotal support structure for locking such structure to said lever member to locate the position of said pivot point along the length of said lever.
