Measurement gauge incorporating a level

Apparatus for a measurement gauge for spacing and leveling parallel members, comprising:

• a) an elongated, planar base having first and second opposing ends, top and bottom surfaces, and first and second edges having a slot between and parallel to said first and second edges, said slot being substantially centrally disposed between said first and second ends and between said first and second edges and extending completely through said base from said top surface to said bottom surface, said slot having first and second ends disposed toward said corresponding first and second ends of said base, respectively;
• b) a rule disposed on each of said first and second edges of said top surface of said base extending substantially from said first end to said second end of said slot;
• c) a first transverse member being adjustably pivotally at a fixed location attached to the bottom surface of said base proximate to said first end of said slot and offset to a side of said slot between said slot and said first edge, said first transverse member having first and second ends and being pivoted about a first knob on the top surface of said base at said fixed location on said base;
• d) a second transverse member being pivotally attached to a second knob on the bottom surface of said base, said second knob being slidable in said slot;
• e) said first transverse member having a level disposed on each of said first and second ends of said first transverse member, said levels viewable from the top surface of said base;
• f) said base having dimensions allowing said first and second transverse members to be rotated to a position on the bottom side of said base so that said first and second transverse members are entirely contained within an area defined by said bottom surface of said base for storage of said apparatus.
