Claim Text:
1. An adjustable tool holding surface grinder fixture comprising: a parallelepiped base having a front portion having a front side and a rear portion having a rear side, each of the front side, and the rear side having a left side, a right side, a top side, and a bottom side, the top side of the rear portion being lower than the top side of the front portion relative the bottom side; an angled notch disposed on the rear portion bottom side proximal each of the left side and the right side; a set-up angle pin having a cylindrical bottom portion disposed on the top side and an annular top portion, the annular top portion having a continuous diamond grained outer surface; a cylindrical stud member vertically disposed on the top side of the front portion proximal each of the front side and the left side, the stud member having a beveled upper edge and a threaded opening disposed proximal the upper edge in a position parallel to the top side; a threaded first clamping screw engaging the threaded opening, the first clamping screw having a rotatable first cap on a posterior end thereof; a central groove centrally disposed on the front portion top side proximal the stud member in a position parallel to each of the front side and the rear side, the central groove having an open end disposed on the left side and a closed end centrally disposed in the front portion on the top side; a forward movement stop pin vertically disposed within the central groove proximal the closed end; a second groove disposed in the front portion top side parallel to and proximal to the central groove in a position more proximal the front side than the central groove; a third groove disposed in the front portion top side parallel to and proximal to the central groove in a position more proximal the rear side than the central groove, each of the second groove and the third groove having an external closed end proximal the left side and an internal closed end disposed proximal the forward movement stop pin, each of the second groove and the third groove having a length shorter than a length of the central groove; a cylindrical rod continuously disposed in each of the second groove and the third groove, the rod partially protruding upwardly from the respective second groove and third groove; a cylindrical aligned pair of side movement stop pins vertically disposed on the front portion top side proximal and parallel the third groove, the pair of side movement stop pins being more proximal the rear side than the third groove; a substantially parallelepiped stop wall vertically disposed on the front portion top side proximal the front side and the right side and perpendicular to the central groove and further parallel to the base right side, the stop wall being more proximal the rear side than the set-up angle pin, the stop wall having a top wall and a front wall, and a decreasing sloped wall disposed between the top wall and the front wall; a support wall vertically disposed on the rear portion top side directly adjacent the rear side, the support wall having an internal surface, an external surface, a left wall, a right wall, an upper wall, a bottom edge, a 45-degree decreasing pre-set angled wall disposed between the upper wall and the left wall; a plurality of adjustment holes disposed on the external surface in a semi-circular configuration proximal the right wall, the configuration initiating proximal the upper wall and terminating proximal the bottom edge; a pair of tap holes centrally disposed between the upper wall and a center of the support wall; a rotatable fixture mount disposed on the internal surface, the rotatable fixture mount comprising: at least one collet holder having an insertable collet, the collet holder removably securable between the exterior surface of the mount disc, the mount bar, and the top side of the base; wherein upon insertion of the respective one of the least one collet holder between the stud member and the side movement stop pins and the stabilization of a forward end of the respective one of the least one collet holder against the forward movement stop pin, a front edge of a metal cutting tool is alignable with one of the top wall and the decreasing sloped wall; wherein upon insertion of the set-up angle pin through the respective aligned adjustment hole and positioning hole, the collet support fixture is secured at one of a plurality of pre-set angles relative the base; and wherein upon insertion of the collet into the collet holder when the collet support fixture is secured at the one of the plurality of the pre-set angles relative the base, an edge of a metal cutting tool is set at a respective angle relative a grinding wheel of a surface grinder.
