ABSTRACT:
A device for use as a measuring tape and as a compass. A hollow housing generally rectangular in shape has a vertical front surface with a lower opening therein and a horizontal bottom surface with a front opening. The lower and front openings join each other. The housing has an inner partition which extends vertically upward from the bottom surface and horizontally inward from the front surface to divide the interior of the housing into a small first compartment formed between these surfaces and the partition and a large second compartment in the remainder of the housing. The partition has an opening in the upwardly extending portion. A measuring tape is disposed in rolled up condition in the second compartment with a front end extending through the partition opening. The tape is manually unwindable. The front end of the tape has a hole. Windup means is disposed in the second compartment to normally maintain said tape in wound up condition. A holder for detachably receiving a chalk or the like is secured to the front end of the tape and extends at right angles to the major surfaces of the tape whereby a chalk disposed in the holder has a tip extending downwardly through the hole. The holder normally fits into the first compartment. A pointed member is secured to said bottom surface of the housing remote from the front opening and points vertically downward.
