ABSTRACT:
The base section of an upstanding, telescoping mast is fixedly anchored in respect to the ground and the top section is vertically adjustable in respect to the base section. A plurality of horizontally disposed swing arms are pivotally supported in spaced vertical alignment along the height of the top section. The radially extending free end of each swing arm is slidably engageable into one end of the message tube of a message holder, in which tube is received a piece of paper on which a message is written. The ends of an arcuate tube are fixedly attached to the opposite end of the message tube to form a closed ring of sufficient diameter to enable an operator, who is passing by on a traveling vehicle, to extend his arm to the ring and pull the message holder free from the swing arm. Spring clips are attached to the free end of a swing arm for both limiting the endwise engagement between the swing arm and the message tube and for resisting rotational movement of the message tube in respect to the swing arm.
