ABSTRACT:
A compass hood construction is disclosed capable of closing entirely the face of a compass yet also providing higher viewing angles than is usually possible with available hood constructions. An outer stationary hood segment frictionally engages an annular flange in which the compass is mounted. Mounted within the hood segment are inner and outer hood sectors which are pivotally pinned to the stationary hood segment. The inner hood sector includes a tongue which engages a groove in the interior wall of the outer hood sector. When fully opened, the hood is defined essentially by the stationary hood segment. When fully extended, the inner and outer hood sectors form a hemispherical enclosure with the hood segment, completely enclosing the compass face.
