Abstract:
A pendulum line level device for measuring the angle of orientation of a workpiece, comprising:(1) an essentially rectangular main body having an essentially square cross-section having a pair of left and right pivoting indicator discs located within said body;(2) wherein each of said left and right indicator discs has a pair of horizontal indicators and upper and lower vertical indicators, and wherein each disc is rotatably attached within said main body, and wherein said lower vertical indicator has a pendulum weight located at its bottom, wherein when said pendulum line level device is tilted to an off-level orientation, the gap between adjacent off-level indicators narrows, thereby producing a pronounced and highly visible sign that the pendulum device and workpiece are off level;(3) calibrated scales located just outside the upper left quadrant of the left indicator disc and just outside the lower right quadrant of the right indicator disc; and(4) an attaching means for attaching the pendulum level to the workpiece.
