To lock the legs in adjusted position the heads h of the legs a, b are bevelled to form between them a V-shaped groove, into which a locking- wedge k is adapted to be pressed by means of a screw on the handle m. The screw passes through a socket l. on which is mounted a sliding collar s connected to the compass legs on opposite sides by two pivoted links t, so as to maintain the handle m in a central position.
