Gim"bal (?), ∨ Gim"bals (), n. [See Gimmal, n.]
A contrivance for permitting a body to incline freely in all directions, or for suspending anything, as a barometer, ship's compass, chronometer, etc., so that it will remain plumb, or level, when its support is tipped, as by the rolling of a ship. It consists of a ring in which the body can turn on an axis through a diameter of the ring, while the ring itself is so pivoted to its support that it can turn about a diameter at right angles to the first.
Gimbal joint Mach., a universal joint embodying the principle of the gimbal. -- Gimbal ring, a single gimbal, as that by which the cockeye of the upper millstone is supported on the spindle.
