ABSTRACT:
A power returnable coilable rule employs a casing which has on the inside surface of one of its end walls a non-circular recess, and a reel which has on its adjacent end wall a recess of similar configuration. Slidably seated in the central passage through the reel is a hub with a barrel portion extending into the passage of the reel and a flange at one end having a cross section dimensioned and configured cooperatively to seat snugly in either of the recesses. In assembling the prewound reel in the casing, the flange is initially seated in the recess of the reel to prevent relative rotation therebetween and thereafter the hub is shifted axially to seat the flange in the recess of the casing so as to permit the reel to rotate thereabout.
