  • Patent number: 3999781
    Abstract: A universal swivel hose coupling which is adapted to be sealably connected to dissimilar externally threaded male fittings. The hose coupling includes a tubular stem having one end adapted to be received into the end of a hose and an opposite end having a forwardly facing frusto-conical surface. A nut is rotatably carried by the stem and includes an entry end portion at the outer end thereof. The frusto-conical portion of the stem is adapted to sealably mate with a male "flare" fitting having a conically tapered forward end conforming to the taper of the frusto-conical portion, and the entry end portion of the nut is adapted to sealably engage the O-ring of a male "straight thread O-ring boss" fitting.

  • Patent number: 3997198
    Abstract: A swivel joint for pressure containing conduits such as movable flow lines may comprise a pair of hub elements each having means establishing interconnection with a section of flow line, the hub elements being abutted in such a manner as to define a flow passage through the swivel joint construction. A thrust flange is formed on each of the hub elements, the flanges being retained within a split housing structure that services to retain the swivel joint in assembly. Rotatable relationship between the hub elements and the body structure is established by a pair of thrust bearings that are interposed between the housing and the respective thrust flanges of the hubs. A lubricating spacer element may be disposed between the thrust flanges of the hubs to prevent the development of friction retardation of swivel movement. The hubs interfit to define a sealed recess within which is received a seal sleeve that is of sufficient length to transition the joint between the abutted hubs.

  • Patent number: 3986732
    Abstract: Dual concentric fuel and vapor recovery hoses are disclosed wherein an inner substantially kink-proof reinforced pressure hose carries fuel while an outer larger diameter extruded cover hose provides a vapor recovery path between the two hoses. The dual concentric hoses terminate into an end fitting that provides for separate rotatability of the hoses while also providing direct fuel feed through the fitting and a parallel vapor recovery path.

  • Patent number: 3980324
    Abstract: This coupling comprises a rotary cylindrical portion which is recessed and an outlet opening whose lower edge is placed level with the lowest point of a surface which is inclined relative to the rotation axis, whereby the said surface is placed adjacent to the axis and the side opposite to the said opening.This coupling is more particularly intended to be used on the inlets and outlets of pneumatic automatic control modules.

  • Patent number: 3957205
    Abstract: A sprinkler having a sprinkler head fixed to a tubular spindle which is rotatably journaled in and spring biased upwardly relative to a bearing sleeve, and improved upper and lower seals for sealing the clearance space between the spindle and bearing sleeve against entrance of water, dirt, grit and the like. The upper seal includes a seal ring which is yieldably retained by the spring in sealing force on the sprinkler head and has a depending annular flexible sealing lip surrounding and engaging a circumferential sealing surface on the bearing sleeve in such a way that if the spindle pressed downwardly through the bearing sleeve against spring action, the seal ring wipes or scrapes dirt and grit from the sealing surface to prevent jamming of the seal ring on the bearing sleeve during upward spring return of the spindle.

  • Patent number: 3937494
    Abstract: A bearing system for relatively rotatable liquid conduits such as a rotating sprinkler head mounted on a fixed riser, including a two-piece casing assembly for shielding operative parts of the bearing from intrusion of external dirt and water-borne abrasive material, while permitting leakage liquid within the casing assembly to bleed outwardly, thereby preventing excessive liquid pressure in the assembly. The illustrative system includes a bearing housing having a central vertical bore and a tubular spindle rotatably mounted in the bore and projecting thereabove for attachment to a sprinkler head. The system includes spaced upper and lower seals between the fixed and rotating parts, and an external helical spring for maintaining the seals under compression, thereby minimizing entry of outside dirt and water-borne abrasive material into the annular space between the spindle and bore.
