Total Claims: 4
Claim 1
Independent Claim
183 words
A tape measure comprising: a substantially rectangular case having a top wall with a front corner edge, a bottom wall with a front corner edge, and an opening in the front corner edge of the bottom wall, a tape being reeled in said case and capable of being drawn out through the opening in the front corner edge parallel to the bottom wall, and a marker mounted on and parallel to the top wall of said case for marking a point or line on a surface of an article being measured, said marker capable of being projected along the top wall of said case but spaced from and parallel to the bottom wall of said case; whereby, upon manual rotation of the front corner edge of the top wall of the case toward the drawn out tape, when pressed against the surface of the article being measured, the marker is projected from the front corner edge along the top wall of said case and comes into contact with the surface of the article so that the measured distance along said surface is marked.
Claim 2
Dependent Claim

A tape measure comprising: a substantially rectangular case having a top wall with a front corner edge, a bottom wall with a front corner edge, and an opening in the front corner edge of the bottom wall, a tape being reeled in said case and capable of being drawn out through the opening in the front corner edge parallel to the bottom wall, and a marker mounted on and parallel to the top wall of said case for marking a point or line on a surface of an article being measured, said marker capable of being projected along the top wall of said case but spaced from and parallel to the bottom wall of said case; whereby, upon manual rotation of the front corner edge of the top wall of the case toward the drawn out tape, when pressed against the surface of the article being measured, the marker is projected from the front corner edge along the top wall of said case and comes into contact with the surface of the article so that the measured distance along said surface is marked.
Claim 3
Dependent Claim
