Abstract: A parking meter has a vault housing and a vault door removably covering a main opening and having a back facing an interior of the housing. A lock assembly includes a lock cylinder disposed on the door and that has a body and a usually movable portion. A bolting mechanism operatively connects to the movable portion of the lock cylinder for selectively providing a locked position. A support structure is disposed on the interior side of the door and holds the bolting mechanism. A removable retainer engages the body of the lock cylinder, which is usually stationary. This results in the retainer preventing motion of the body sufficient to operate the bolting mechanism. The support structure is configured for releasably maintaining the retainer on the lock cylinder body. The vault housing defines a tool hole providing access to the interior of the housing for insertion of a disengagement tool through the tool hole.

Abstract: A parking meter consisting of a housing and a stanchion located adjacent a parking space for mounting of the parking meter thereon. The stanchion has a tubular upper end portion and the parking meter has a tubular lower end portion for positioning around the upper end of the stanchion. A fitting is attached to the upper end of the stanchion and gear teeth are defined by the fitting. The lower end of the meter housing has formed therein a set of gear teeth adapted to mesh with the gear teeth of the fitting in any one of several available relative positions. A bolt and pin combination is employed for providing a high security connection of the fitting and upper housing to the stanchion. Passages are provided so that rainwater and the like is directed outside of the housing and stanchion and does not accumulate within the meter housing.
