Abstract: An improved coupler or tapping mechanism and valve system for obtaining access to a container of fluid. In a container of fluid, and particularly a keg for beer, a valve assembly receiving member or keg neck extends from the top of the container. This keg neck receives a flat top, dual valve system which is operated by the coupler. The improved coupler is placed over the keg neck and is positively secured thereto and sealed relative to the valve assembly by a two point locking mechanism which engages the external surfaces of the keg neck. A safety locking mechanism is provided which prevents removal of the coupler from the keg neck as long as the dual valves are in an open fluid tapping position.

Abstract: A sealing element which is particularly adapted for use in preventing fluid flow between threadably interconnected components. The sealing element comprises a rigid portion formed of metal or the like and an elastomeric material portion. These portions are assembled together in a geometric configuration that protects the elastomer from shear forces and at the same time permits close control over the compression forces which can be exerted on the elastomeric portion of the sealing element. In this way, both overcompression and shear damage to the elastomer are effectively prevented.

Abstract: An improved locking mechanism and valve system for obtaining access to a container of fluid. In a container of fluid, and particularly a keg for beer, a valve assembly receiving member or keg neck extends from the top of the container. A sealing mechanism is provided to secure the valve assembly in sealed relationship with the keg neck and to allow access to the fluid contained by actuation of the valves. More specifically, the valve neck has a groove in its inner surface to receive a resilient retainer ring which maintains the valve assembly in place. In addition, an improved dual keyway, dual key safety feature is provided to prevent inadvertent expulsion of the valve assembly should the retainer ring be dislodged while the keg is pressurized. This improvement also decreases the likelihood of damage to the valve assemblies during their installation and precludes accidental or intentional infliction of damage to the safety keys carried by the valve body of the system.

Abstract: A safety pressure reducing regulator for use in systems operable by pressurized gas incorporates multiple safety features which preclude excessive pressure buildup in the system and provide protection against catastrophic failures. The regulator includes primary and secondary regulator stages through which pressurized gas from a gas pressure source is supplied to a pressure control chamber which provides the operating pressure for the system. The primary regulator stage is designed to reduce the inlet gas pressure to an intermediate level. The secondary regulator stage is designed to automatically regulate the supply of the pressurized gas at the intermediate pressure to the pressure control chamber to maintain a desired operating pressure therein. A flexible diaphragm is normally disposed across the pressure control chamber which is adapted to function as a check valve to control communication between the secondary regulator stage and the pressure control chamber.

Abstract: The safety device is disposable in the gas line connecting between a gas source under pressure and a tapping device installed in a keg. The safety device includes a valve housing carrying a spring biased, axially movable piston assembly including a valve body and an axially movable stem element. Upon an increase in gas line pressure above a predetermined pressure, the gas acts on the piston assembly to displace it as a unit in an upstream direction against the bias of the spring to seal the stem against a primary valve seat element and preclude further ingress of gas into the keg. However, should the primary valve seat element leak, due to wear or contamination, causing pressure within the system to increase, the valve body will move relative to the valve stem to vent the housing to atmosphere and to close a secondary valve seat adapted to positively prevent further fluid flow downstream of the device toward the keg.

Abstract: Method and apparatus for restraightening depending bent metal end skirts of cylindrical containers, such as beer kegs, wherein the containers moving in a path of travel for processing are automatically interrogated by sensing heads which engage the rims of the normally circular end skirts of the containers to detect the presence or absence of a bent portion thereof. Containers having detected bent skirt portions are directed from the main processing path to a skirt straightening station where the ends of the container are supported in retaining rings of upper and lower straightening heads while arcuately spaced pry levers, or paws, located centrally in each retaining ring move radially outward from a central nested position to engage inwardly bent skirt portions of the container to lift and push the same outwardly into a circular configuration. The container is rotated in the rings between engagements by the paws to bring all portions of the skirts into position for straightening.

Abstract: A combined fluid pressure gage and safety pressure relief device for interconnection with systems wherein excess fluid pressure will cause explosions likely to result in injury to personnel and damage to surrounding equipment. The device accurately measures fluid pressure within the system to which it is connected so long as the system pressure remains within the working range of the pressure gage. However, should the system pressure exceed the normal full scale pressure reading on the gage, the device will instantly and automatically safely vent the system to atmosphere. Once the device is vented the pressure relief mechanism must be manually reset by skilled technicians using special tools before the apparatus can be reused.

Abstract: A compact, self-contained device for use in safely lowering filled beer kegs from the bed of a delivery truck to the ground. The device includes a hollow drum rotatably carried within a sealed housing which can be removably interconnected to a rigid support in the load bay of the truck. A length of cable is wound about the drum and the free end thereof is connected to the keg chimes by means of a unique harness assembly. When the keg is pushed from the truck the cable is uniformly paid out from the drum against the urging of a rewind spring. The rate of descent of the keg to the ground is precisely controlled through a speed increaser housed within the drum which drives a novel centrifugal brake at high speeds producing a predetermined amount of drag on the drum. Upon disconnecting the harness assembly the cable is automatically rewound on the drum by the rewind spring.

Abstract: A system for dispensing fluid from a container. The container is pressurized by supplying gas into the container thereby forcing the fluid out of the container through a siphon tube and an outlet valve in the container. The system utilizes a valve assembly having two valves, one for enabling the flow of the gas into the container and the second for allowing the flow of the fluid out of the container. 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: A safety valve for use with a beverage dispensing system having a pressurized source connected through a conduit to a container of beverage. The safety valve includes a housing having an inlet for connecting said valve to the pressure source and an outlet for connecting the valve to the beverage container through the conduit. A chamber in the housing is divided into at least two subchambers by a rupture disc which ruptures at a predetermined pressure in one of the subchambers. The other side of the disc is exposed to a subchamber which is vented to the atmosphere. Where the pressure in the one subchamber reaches the predetermined level, the rupture disc will burst allowing the pressurized gas to flow out through a vented chamber into the atmosphere, thereby preventing the container from being over-pressurized.
