Machinery mount anchor base fixture

A fixture for drilling holes to receive fasteners for a machine supporting mounting anchor mounted on a drillable surface wherein the anchor includes a pair of semi-spherical recessed fastener receiving openings, an opening being located on opposite sides of a pedestal defined on the anchor and the anchor pedestal engaging a lower surface of the machine being supported, the fixture comprising a frame, said frame including a bridge for bridging the anchor pedestal and having ends, each bridge end having a lower surface and an upper surface, a projection defined upon each bridge end lower surface adapted to be received within an anchor recessed fastener receiver opening, a vertically disposed retainer mounted upon each bridge end upper surface having an upper end adapted to engage a lower surface of the machine being supported, a tubular drill guide mounted upon each bridge end upper surface having a bore having open upper and lower ends and extending through the associated projection, and frame angle positioning means mounted on said frame adapted to engage with the machine being supported, said retainers and said angle positioning means being on opposite sides of the vertical projection of a plane passing through the centers of said projections whereby said frame may pivot about said projections within the anchor fastener receiving openings and compressive forces within said retainers and angle positioning means firmly pivotally position said frame relative to the anchor permitting said drill guide bores to receive and guide a drill drilling into the drillable surface for the machinery supporting mounting anchor.
