ABSTRACT:
The visual indicating system comprises, in one embodiment, a number of pivoting sub-assemblies borne by the carrier so constructed that they are impelled axially upon making contact with the top of the pole, they pivot. Attached to a horizontal portion of each pivoting sub-assembly below the carrier is a shield that normally covers a brightly colored area on the undersurface of the carrier. However, when the subassembly pivots, the horizontal portion moves aside so that the area is visible from the ground. In another embodiment, the pivoting assembly includes a brightly colored flag between the carrier and the masthead which is normally unseen from the ground until the carrier approaches a predetermined position toward the top of the pole whereupon the flag is caused to pivot outwardly of the carrier into view from below.
