Abstract

The leg of the compasses carrying the lead is bent at its knee joint so that the point of the lead is close to the metal point of the other leg. The leg (1) of the compasses which carries the metal point (20) is bent inwards at its end (15). The pin (18) is inserted in a hole in the bent portion (15) of the leg (1) and secured by a locking screw (17). The pin (18) is cranked so that its lower end (21) can touch the point of the lead (12).
