  • Door lock with decorative escutcheon
    Patent number: 3965710
    Abstract: A door lock in which a decorative escutcheon is telescoped onto a tubular barrel which houses a lock cylinder. A key on the escutcheon fits into a slot in the barrel and normally holds the escutcheon in a proper angular orientation with respect to the barrel. If the escutcheon is forcibly turned with a pipe wrench or the like, the key shears away and allows the escutcheon to spin freely on the barrel so as to prevent torque from being transmitted to the barrel.
