Adjustable parallel machine tool

An adjustable machine parallel comprising:

• a. a wedge-shaped slide having upper and lower planar surfaces, and a threaded opening with an axis parallel to said lower surface of said slide;
• b. a wedge-shaped base having parallel sides and upper and lower planar surfaces;
• c. said lower planar surface of said slide in sliding contact with said upper planar surface of said base, said upper planar surface of said slide parallel to said lower surface of said base;
• d. a slide support integrally attached to said base having a longitudinal aperture therethrough with an axis parallel to said lower planar surface of said slide and said upper planer surface of said base, said aperture in registry with said threaded opening, said slide support having a second threaded opening perpendicular to and intersecting said aperture;
• e. a screw disposed in said aperture having a threaded end engaging said threaded opening;
• f. means for rotatably retaining said screw within said aperture;
• g. said screw having a radial groove therein, said slide support having a first opening perpendicular and tangential to said aperture and said means for rotatably retaining said screw including a pin disposed in said first opening engaging said groove;
• h. a ball disposed in said second threaded opening engaging said groove;
• i. a screw having a threaded end engaging said second threaded opening and retaining said ball in locking engagement with said groove;
• and
• j. said first opening being perpendicular to said second threaded opening.
