Principles of operation

The lock features seven spring-loaded levers which must be slid to the correct position to allow the probe to enter the gates on each lever. The levers are serrated in order to cause false sets and the keyway is closed off by a rotating curtain to prevent manipulation and decoding. The probe is not connected directly to the bolt but rather to a separate lever which blocks the bolt from moving unless it can enter the gates. The fence lever and bolt is connected mechanically to the curtain and their movement is powered by the key-turning action. This key mechanism derives ultimately from Strutt's lever lock of 1819 — the first to use end-gated levers.
