ABSTRACT:
The present invention utilizes a segmented collar formed from at least three collar segments, which are placed in end-to-end relationship to form a circular collar having a central opening therein for receiving a surveyor's stake. The collar segments are secured together by bolts extending through flanges at the adjacent ends of the collar segments. The tripod includes three legs, the upper ends of which are secured between the adjacent flanges of the collar segments. The bolts extending through the adjacent flanges and through the upper ends of the tripod legs are adjustable to tighten and loosen the hinged connection of the legs to the collar. Thumb screws extend through each of the collar segments for threadable movement inwardly toward the surveyor's stake located within the stake receiving opening.
