Abstract
An extreme service measuring tape assembly especially adapted for deep sea diving use includes a rugged, easily cleaned and inspected assembly having a split case in which mating peripheral threads and an angled tape slot permit the two halves of the case to be screwed together, the angled tape slot being "L" shaped in one of the case halves with a portion matching a conventional tape slot in the other case half to accommodate the tape in slewed position permitting screwing the case halves together, followed by restored position for use of the tape in measuring; interlocking double spool structure aids guide and positive assembly; compass, magnet, securance, and special polygonal case shape are included in the preferred embodiment.

In a measuring tape assembly with an extensible and retractable tape mounted on a spool in a case divided transverse to the spool axis into two parts and having a peripheral portion around the spool with structure defining an opening for passage of the tape, and means for winding the spool, the improvement comprising:
- the two case parts including a front and a back with integral means detachably joining the front and back, the detachably-joining means including the front and back each having a respective screw thread around said peripheral portion, and said structure defining the tape opening in the form of an "L" shaped slot with a horizontal portion extending across said front and back for holding the width of the tape partly in said front and partly in said back and with a vertical portion in said front for receiving the tape width vertically therealong for clearing the tape from said back and permitting said front and back to be rotated relative to each other on said screw threads for assembly and disassembly of said measuring tape assembly.
In a measuring tape assembly with the tape mounted on a spool in a case divided transverse to the spool axis into two parts and having a peripheral portion around the spool with structure defining an opening for the tape, and means for winding the spool, the improvement comprising:
- the two case parts including a front and a back with integral means detachably joining the front and back, the integral detachably joining means including the front and back each having a respective screw thread around said peripheral portion, said structure defining the tape opening in the form of an "L" shaped slot, the "L" shaped slot including an "L" shaped portion in the front with a part thereof vertical and proportioned for receiving the tape width therealong, and said structure defining a horizontal portion of the "L" shaped slot in the back.
