Abstract

The instrument can check, in-situ or remotely, the verticality of a plane surface or a straight edge. It may also provide means for the automatic return to the vertical. The instrument comprises a plumb line enclosed by a rigid or a flexible sheath. Externally to the sheath there are two locating bosses. Internally to the sheath, there are switch contacts to locate the position of the plumb line. The plumb line itself may be electrically conducting and swings against contacts completing electric ccts. actuating a display an alarm or means for bringing the instrument and its mounting back to vertical.
