Abstract:
A valve box lock for preventing unauthorized access to a shut off valve including a security bolt extending through a hole in a valve box cover and received into a threaded hole in a cam piece mounted to the undersurface of the cover, the cam piece is moved up and down by rotation of the security bolt in either direction. The cam piece engages a pair of locking plates which are moved radially out into engagement with an inner surface of the valve box to prevent removal of the cover when the security bolt is rotated in one direction, or are retracted radially to release the cover so as to be able to be removed. A automatic lubricating arrangement is associated with the security bolt to insure that it is able to be turned by excluding any.
