Abstract
Abstract A measuring or like device having a casing with a front wall opening adjacent a bottom wall and a tapeline coilable in the casing and movable out the opening to various projected positions, and wherein an actuator projecting from the front wall of the casing and journaled for pivotal movement from a first pivoted position to a second pivoted position moves a vertically slideable tapeline lock from a position out of braking engagement with the tapeline down to a position in which it resiliently clamps the tapeline against the bottom wall of the casing and holds it in a particular position of extension, cams interconnecting the lock and actuator being operable to cam the lock down to clamp the tapeline when the actuator is pivoted from the first to the second position and to lift the lock up to release the tapeline when the actuator is returned.
