ABSTRACT:
A coilable rule having a replacement cartridge comprising a hub, a spool for winding the tape and a keeper for maintaining the cartridge in factory adjusted position until it is field-installed in the tape casing is disclosed. The spool has a single side flange journaled on a hollow hub which is non-rotatably mounted within the casing with the hub providing a second side flange to define an annular spring chamber with the hub flange spaced from the spool by an annular clearance to prevent frictional contact and provide a unit bearing construction for the spool so that the spool is self-aligning. The keeper is snap-fitted into one of a plurality of non-circular openings in the hub flange and a central post passing through the hollow hub fixes the distance between the sidewalls of the casing to provide an axial clearance with the hub to accommodate the axial movement thereof.
