ABSTRACT:
A fixture form of apparatus is provided which performs in conjunction with a typical bench grinder to retain and maneuver implements having to be sharpend such as mower blades. The apparatus includes a base member upon which is mounted a forwardly disposed hinge assembly. From this hinge assembly extend paired parallel cylindrical guide rods which form the raceway of lateral bearings, in turn, supporting and forming part of a carriage assembly. On the carriage assembly, there is mounted a clamping mechanism formed of a portion of conventional over-center gripping pliers which are pivotable about a grip axis and, further, a bracket supports the gripping components to achieve pivotal adjustment about a bracket axis. Implements are mounted in the apparatus after it is pivotally maneuvered rearwardly to a mount position spaced away from the grinding environment. The assemblage may be provided with a cutting depth bracket to simplify the sharpening process as well as a base position adjustment assembly serving to provide more accurate base positioning upon a work surface before the bench grinder assembly.
