gimbals

gimbals, two concentric metal rings which form the mounting and suspension for the compasses and chronometers on board ship. The rings are mounted on knife edges, the bearings of one being fixed fore and aft in the ship's line and the other athwartships, thus allowing the compass or chronometer to remain level irrespective of the rolling or pitching of the ship. Gimbals are also used to mount lamps, cooking stoves, etc. in small vessels. The earliest description of a gimbal mounting dates from the beginning of the 17th century.
