  • Patent number: 9290916
    Abstract: A removable hydrant nozzle with a locking arrangement for securing the nozzle in a nozzle opening. The locking arrangement includes an axially movable slide configured to selectively engage a portion of the hydrant adjacent the nozzle opening, such as a lug mouth in a quarter-turn fitting. The slide is mounted to a slide housing and is spring loaded. In use, the slide automatically retracts as the nozzle is inserted into the nozzle opening and automatically extends into locking engagement with the mouth when the nozzle becomes fully seated. Once engaged, the slide prevents removal of the nozzle until manually disengaged. The slide may be movably mounted on a pair of shoulder bolts. The slide may include a paddle that extends outwardly where it is accessible to the operator. The nozzle may include a handle and a seal fitted onto the inner axial end of the nozzle.

  • Publication number: 20080150280
    Abstract: A coupling comprising a receiving part (1), a securing part (9) and an insertion part (17) includes blocking elements (6, 13?) whose engagement preventing the securing part (9) from moving from an extended position into a retracted position is released by the axial displacement of latching arms (13) of the securing part (9) of said insertion part (17), such that when the insertion part (17) is properly arranged in a receiving space (16) of the receiving part (1), the securing part (9) can be shifted into the retracted position in which said insertion part (17) is secured. What is achieved in this way is relatively simple modification of the assembly force through design measures, high wear resistance, and simple and operationally reliable manipulation of the inventive coupling with regard to the release of the connection between the receiving part and the insertion part, especially under confined spatial conditions.

  • Patent number: 6062609
    Abstract: The cuff (25) for connecting a tube (26) to two pipes (2) or two equipments together includes, at each end, a knuckle joint mechanism (31) bearing on a clamp (3) integral with the pipe (2) and which forces the end of the tube (26) against the mouth (4). The knuckle joint (31) is two pairs of rods (32, 35), whose interference produces a compressive stress on spring washers (37). The fixing force is consequently applied in simple and reliable manner and can be interrupted just as easily. The bearing surfaces of the connecting parts and the tube (26, 30, 43) with respect to one another, on the clamp (3) and the mouth (4) must be spherical and concentric in order to enable the pipes (2) to be angularly displaced by a few degrees relative to the tube (26).

  • Patent number: 4103712
    Abstract: A disconnect composed basically of two halves each consisting of a poppet valve operable to isolate fluid with essentially zero fluid loss. The two halves are coupled together by a quickly releasable coupling which may be either a coupling ring tightened or loosened by a twisting motion, or a clamp operated by a pivoted handle. In either case an interlock device is provided to prevent disconnecting the two halves until both valves are in closed condition.The "positive" feature of the device is one requiring a valve closing step before a disconnect step, and takes structural form in an eccentric lobe mounted on the valve operating stem. If some obstruction prevents the poppet from moving to its seat, the eccentric lobe cannot be rotated to the closed position, and the interlock prevents a disconnect.

  • Patent number: 4048267
    Abstract: The downcomer through which air is supplied to a header for liberation of air deep in an aeration tank is of straight-line nature to minimize constant waste of power due to air flow friction. The downcomer nevertheless folds when the header is to be raised for inspection or servicing. The folding axis is external of the downcomer, which breaks open as the folding action starts. In one form the header is straight while initially raised, hanging from a first hoist cable, and then as the lower section is raised further by a second cable the upper section is allowed to fold over. In another form, the folding progresses as the structure is raised, the upper section being hinged to the air supply fitting.
