Ruler with magnifying cursor

A measuring device for determining the length of an object or distance comprising the combination of:

• an elongated base having a central recess separated by a pair of edge marginal regions having opposing wall surfaces defining said central recess;
• said base recess characterized as a T-shaped recess having a pair of opposing slots in said wall surfaces of said respective edge marginal regions;
• a first one of said edge marginal regions having a plurality of line increment marks as a measurement scale carried along a straight edge against which the object or distance is measured;
• two rows of staggered numerical indicia of different fractional values carried on said base at the bottom of said recess and each numerical fractional value assocated with and aligned with a particular line increment mark of said measurement scale;
• a cursor composed of transparent material movably carried on said base and having an index marker carried on a cantilevered finger over said measurement scale adapted to be registered with a selected one of said line increment marks at the end of the object or distance to be measured;
• said cursor further having a magnifying means centrally disposed thereon in linear alignment with said index marker and immediately about said recessed display of numerical indicia whereby alignment of said index marker with selected line increment marks reveals an enlarged display of a selected numerical indicia of a given fractional value;
• and
• framing means carried on said cursor on either side of said magnifying means for obscuring non-selected numerical indicia.
