Abstract: A gun barrel cooler for cooling a firearm, such as an automatic, semi-automatic, bolt action or lever action rifle that includes a centrifugal fan blower with an intake to which ambient barrel coolant air is discharged from the blower where the air flows through a conduit that preferably is a flexible hose, through a coupling used to couple the hose to a barrel coolant discharge nozzle, and out the nozzle into the barrel of the gun desired to be cooled. The nozzle is three dimensionally shaped to substantially conform to the firing chamber of the gun to provide better sealing during cooling. A preferred nozzle is an empty cartridge case of substantially the same caliber as the gun to be cooled that is removably attached to the coupler thereby enabling cartridge cases of different calibers to be used to cool guns of different calibers.

Abstract: A moisture release valve for an outdoor light including a valve body having a stem received in a valve guide and having a head seating with a valve seat integrally formed of part of a sidewall of a light casing of the light fixture. Valve body is gravity displaced between a closed position and an open position depending upon light fixture orientation and can include a counterweight carried by its stem interiorly disposed within the fixture helping to cause displacement of the valve body toward the desired open or closed position in response to a change in light fixture orientation. Valve body can be a rivet, such as a split rivet, and the counterweight can be a washer, such as an annular washer, having an opening generally in registry with the valve guide permitting fluid within the fixture to drain from the fixture when the valve is open.
