It is, accordingly, an object of the present invention to provide a new and improved parking meter having a structure for reducing the effects of corrosion, particularly in environments where the parking meter is subjected to salt water laden air.
In accordance with the present invention, a parking meter includes a metal structure electrically and mechanically connected to a region of the meter where corrosion tends to occur. The metal structure is also inserted into the earth in the vicinity of the parking meter. The region is where first and second parts have contacting metal surfaces such that corrosion tends to occur at and in the vicinity of the region in response to electrolysis induced electric current having a tendency to flow between the contacting metal surfaces. The metal structure shunts to the earth the current having a tendency to flow between the contacting metal surfaces.
In the preferred embodiment, the parking meter first part is the vault for receiving tokens or credit or debit cards, and the second part is the mounting plate.
The metal structure includes (1) a metal rod extending through the pole and the concrete structure into the ground, (2) a second metal mounting plate at the region, and (3) a metal wire mechanically and electrically connected between the second mounting plate and the metal rod so it extends between legs of the spider. The metal rod, wire and second mounting plate are preferably made of the same high electric conductivity metal, e.g., aluminum, to provide a high conductance electric shunt between the region where corrosion tends to occur and the earth. Because the metal rod, wire and second mounting plate are preferably made of the same metal, electrolysis does not tend to occur between the intersecting surfaces thereof. The second mounting plate is preferably secured in place by the spider attachment bolt, the mounting plate and the interior face of the vault base.
The above and still further objects, features and advantages of the present invention will become apparent upon consideration of the following detailed descriptions of a specific embodiment thereof, especially when taken in conjunction with the accompanying drawings. Modern firearms utilize cartridges, which are a single unit of ammunition that combine a bullet, a propellant, and a primer within a cartridge case. The primer is a small charge of an impact-sensitive chemical mixture. The method of ignition of the primer is used to describe the type of cartridge. Rimfire ammunition locates the primer inside a

 It is, accordingly, an aim of the present invention to leave a new and improved parking meter suffer a structure for dilute the effects of corrosion, particularly in environments where the parking meter is subjected to salt water laden breeze. 
 In accordance with the present invention, a parking meter includes a metal social organization electrically and mechanically connected to a region of the meter where corrosion tend to occur. The metallic element structure is also inserted into the earth in the vicinity of the parking meter. The region is where inaugural and second parts have contacting metal surfaces such that corrosion tends to occur at and in the vicinity of the region in response to electrolysis induced electric current having a tendency to flow between the contacting metal surfaces. The metal social organization shunt to the earth the stream have a leaning to flow between the contacting metallic element surfaces. 
 In the preferred embodiment, the parking meter first contribution is the vault for receiving tokens or credit or debit cards, and the second character is the mounting plate. 
 The metal structure includes (1) a metal perch extending through the pole and the concrete structure into the ground, (2) a second metal mount plate at the region, and (3) a metal telegram mechanically and electrically connected between the second wax plate and the metal perch so it extends between legs of the spider. The metallic element rod, telegram and second mounting plate are preferably made of the same gamey electric conductivity metal, e.g., aluminum, to provide a high conductance electric shunt between the region where corrosion tend to occur and the worldly concern. Because the metal rod, wire and second mounting plate are preferably make of the same metal, electrolysis does not tend to happen between the intersecting surfaces thereof. The second mounting plate is preferably secured in place by the spider fastening bolt, the mounting plate and the interior face of the vault base. 
 The above and still further objects, feature and advantage of the present invention will become apparent upon consideration of the following detailed descriptions of a specific embodiment thereof, especially when take in conjunction with the accompanying drawings. advanced firearms utilize cartridges, which are a single unit of ammunition that unite a bullet, a propellant, and a primer within a cartridge case. The primer is a small care of an impact - sensitive chemical mixture. The method of ignition of the primer is used to trace the type of cartridge. Rimfire ammunition locates the primer inside a
