ABSTRACT:
A pendulum level which is a combination pendulum and level. It includes a rectangular frame with no back and front panels and two spaced cross bars, a pendulum that is pivotally secured to one of the cross bars and detachably secured to the other cross bar, and a level which is adjustably secured to the side of the frame. The location of the pivot point of the pendulum and the use of a longer and heavier pendulum allows the pendulum to swing freely yet quickly settle to the truly vertical. The pendulum type operation depends only on gravity for accuracy and will not get out adjustment as presently made levels do. A long vial is used in the level because it is more accurate, easier to see and use. The mounting system of the vial allows for the adjustment of the vial when it is not true. The vial is exposed for easy cleaning.
