Image Number 7 for United States Patent #4028813.

A sun compass comprises a base, including a transparent hemisphere, a body movable within the base, and a plate including a dial face movable upon the body. Actuating members are connected to the plate and body for selectively moving the plate relative to the body and moving the body relative to the hemisphere. The actuating members are accessible externally of the hemisphere and include rotatable knobs having scales associated therewith for indicating the amount of movement of the plate and body. A transparent hemispherical top is mounted over the base hemisphere.
