ABSTRACT:
A measuring tape assembly comprises a housing containing a rolled measuring tape which extends through a lower hole in a front wall of the housing. The upper portion of the housing contains a flashlight which directs light at an angle through an upper portion of the front wall. A switch is positioned at the top of the housing near the front wall and a tape engaging clamp is positioned on the bottom of the housing near the front wall. A spring biases the clamp into engagement with the tape so that the tape is held in any desired extended position. Pressing the clamp upwardly against its spring permits the tape to withdraw back into the housing under the influence of a conventional spiral spring which is connected to the measuring tape roll.
