I have heard people advance a variety of theories over the years as to what this lock is for, but seldom does a user of a safe know the original intent behind this feature. Little locks like this, which restrict the ability to tun the dial, were used for a practice known as "Day Locking." If a safe or vault door needs to be repeatedly opened and closed and if dialing the combination every single time is deemed to be a hassle (and if the powers that be also want to discourage back-dialing by a casual passer-by) then this little lock cylinder can be used to immobilize the safe dial right near the drop-in point such that the door is "locked" but the wheel pack inside the safe isn't scrambled randomly. If a safe or vault is "day locked" then the user with the dial key can approach, quickly free the dial, and rotate it perhaps a quarter turn and immediately open the door. It certainly isn't a practice to be used in high security environments, but many mechanical safe locks still support it. So now you know.
