  • Gun laying
    Patent number: 4961369
    Abstract: A gun laying aid for determining the offset in the bearing of a gun due to trunnion tilt. The gun laying aid has a support member on which are rotatably mounted a bearing indicator member and a reference member. A correction indicator is pivotally mounted on the reference member and held in contact with an indicator portion of the bearing indicator member. When correctly orientated, as indicated by the level indicating means, the amount of rotation of the correction indicator relative to the reference member is indicative of the offset of the gun bearing due to trunnion tilt, which rotation is measured by the measuring means.
