Abstract: A fire hydrant nozzle assembly which permits a bronze fire hydrant nozzle to be readily and simply attached to a cast iron hydrant barrel without the use of lead caulking, screw threads, or other methods generally requiring machining. Un-intentional removal of the bronze nozzle as a result of the application of relatively high torque typically required to remove a protective cap is effectively prevented. To provide these features, a bronze nozzle member is retained within a hydrant boss member by means of a bayonet type or breech lock type mechanism involving cooperating lugs, and a resilient seal such as an O-ring is provided. For locking the nozzle member in its installed position, a pin element passes through a pair of corresponding apertures in confronting surfaces of the boss and nozzle members. The installed position is positively defined by respective locating engagement surfaces carried by the boss and nozzle members, which surfaces serve to limit rotation.

The valve assembly is mounted in a neck member that is secured to an opening in one of the walls of the container. Arranged within the neck is a deformable seal that is compressed between a body portion of the valve assembly and an inner surface of the neck member. A non-threaded retaining ring holds the valve body portion of the valve assembly within the neck member and serves to apply the force to the valve body portion for compressing the seal.

Abstract: Method and apparatus for effecting perforation of a well casing with a casing gun while maintaining pressure in the well bore at a lower level than the pressure in the surrounding reservoir at the point of perforation. Before production tubing is run into the well, the casing gun is deposited in the bore below the desired production level. After the tubing is installed, borehole pressure is reduced to the desired level by swabbing the tubing and an automatic coupling and decoupling pickup tool is lowered on a wireline through the tubing and attached, mechanically and electrically, to the casing gun. The casing gun is then raised to the production level, as measured by locating the casing collars. When the gun is properly located, it is activated through an electrical cable carried along with the wireline. The casing gun perforates the well casing and surrounding formation, and is then decoupled from the wireline to be left in the well.
