Abstract: An improvement for the structure of end hook for the tape measure consists of a U-shaped flexible elongated metal folder and a conventional end hook. The U-shaped flexible elongated metal folder, having a slim parallel gap which is slightly greater than the thickness of the metallic tape, sandwiches the tape therebetween at the outer end of the tape below the end hook. At the outer edge of the tape, there is a rectangular notch, whose depth is equal to or a little greater than the thickness of the end hook. The flexible elongated metal folder is longer than the end hook, with the closed end thereof engaging the said rectangular notch, so that there is an extended portion stretching beyond the inner end of the end hook. The conventional end hook is mounted on the said metal folder and the tape, overlapping with the metal folder and the tape, then all these three elements are riveted together. The extended portion of the metal floder without overlapping with the end hook is riveted with the tape only.

Abstract: A housing substantially with a rectangular-box shape containing a flexible measuring tape stored therein and a tape-opening provided on the upper face thereof. An ink box containing ink and an ink thread is provided on the front face of the housing. The outermost end of the ink thread is attached to a needle grip with a needle. A level is provided on the upper face of the housing. A pivotal centering needle is provided on a position of one side face of the housing proximate to the tape-opening. The centering needle is used as a centering arm for a pair of compasses while the measuring tape is used as a cantilever arm for determining the radius of an arc or a circle. A pivotal plate set of the first side face of the housing and a hook member set of the opposite face, together with the ink thread pulled out, provide the function of a plumb rule for determining the vertically of a perpendicular plane.
