ABSTRACT:
A power recoilable rule includes an elongated housing with a longitudinal dimension which is greater than its height dimension and having a width dimension which is lesser than the height dimension to enable comfortable gripping of the housing by the hand of a user. Mounted in the chamber at its forward end is a blade reel and at its rearward end is a spring motor with a casing and a spring coiled about its hub. Both hubs are mounted on the housing for rotation about transverse parallel axes. Gears on the hubs of the blade reel and spring motor are drivingly engaged with a drive transfer gear and the gear ratio of the blade reel gear to the drive motor gear is at least 2:1. The housing is desirably configured with a reduced height at its rearward end to facilitate gripping.
