Rim Locks

The Locksmith Dictionary defines a rim lock as;

a lock or latch typically mounted on the surface of a door or drawer. 

In addition to the potential for having a different operating mechanism, the rim lock may be offered with different functions.  For example, it could contain a simple latch, or it could be a dead bolt.   The image shows clockwise from 12, a nightlatch, a bit key lock that could be a lever lock or just warded, and a drop bolt or Jimmyproof deadbolt.  There are four general types of deadbolts.
