Excerpt from
Issue #194 March 2007


This is a simple lock for a small gate with two wards and one tumbler. A ward is any kind of obstruction a key must pass through to operate. In this case the ward is a cylindrical strip on the inside of the cover plates. The tumbler is a part that must be lifted by the key into an exact position to allow the lock to operate. Since the wards and the key bit are symmetrical, the key can operate from both sides of this lock.
