  • Patent number: 4905965
    Abstract: An improved quick-disconnect hose coupling comprising a female coupling half having a ball valve designed with positive interlocking means for retention of a male coupling half in a receptacle formed therein. The ball valve is enclosed in a housing and is arranged to be pivotable therein about an axis, such that the male coupling half communicates with a bore hole in the other end of the ball valve. Pivoting movement of the ball valve provides a flow connection by bringing the bore hole into communication with a hose connector element retained in the other end of the housing, while interlocking pins contained in the ball valve mechanically engage the male coupling half in the receptacle. In one embodiment, a releasable latch engages a contoured slot in the housing for providing positively defined valve operating positions, such that the mechanical connection is completed prior to and separate from the flow connection.

  • Patent number: 4903992
    Abstract: A connection assembly secured a running tool into a tubular casing hanger. The connection assembly includes a frusto-conical threaded section on a running tool and a nose section of cylindrical shape located below the threaded section. The casing hanger has a bore with at least one circumferential recess. A collet ring having internal threads is initially carried on the nose section. The collet ring lands in the recess when the running tool is moved into the casing hanger. Continued movement causes the collet ring to deflect outward. The collet ring has threads on its inner diameter that slide on the threads of the running tool to latch the members together. Slots in the collet ring enable the outward deflection to occur. A pin engages the collet ring to enable rotation of the running tool relative to the collet ring to unscrew the members from each other.

  • Patent number: 4844513
    Abstract: This invention relates to a peripheral connector for a standard coupler, which permits the coupler to be remotely connectable and disconnectable. A male unit and a female unit of the invention enclose a male half and a female half of the coupler, respectively, and cover them with protective boots. A female unit projects an assembly, thereby opening the boot covering the female coupler half. The projected assembly pushes against portions of the male unit, opening the boot covering the male unit, and connecting the coupler. Disconnection is accomplished by moving the projected assembly in the opposite direction.

  • Patent number: 4709454
    Abstract: An axial locking device having two separable members which can be locked together and unlocked by relative axial movement of the two members in one direction. A slider is incorporated in one of the members and is movable relative to the member against a spring when the two members are moved axially relative to one another in one direction. The slider is displaced in one angular direction by interengagement of mutually engageable teeth on the one member and on the slider each time the slider is moved axially. This angular displacement of the slider locks the two members together when they are first pushed axially together against the force exerted by the spring on the slider and then unlocks the two members when they are subsequently pushed axially together against the spring force to permit one handed and/or speedy operation of the locking device.

  • Patent number: 4696497
    Abstract: The invention proposes a quick connection which has utility in a wide field, for instance, for connecting fluid lines, electric cables, etc., and comprises an inserted tubular end portion, which is formed near its extreme end with concave recesses serving as detent means, and which is provided with a radially acting locking collar. The second tubular end portion comprises a socket, which contains an inserted locking ring, which has detent fingers, which releasably interlock with the concave recesses of the inserted tubular end portion and are provided on their back side with reversely foldable, thin webs which bear on the inside surface of the socket. Such quick coupling can be resiliently interlocked simply in that the tubular end portions are urged into each other, and can be unlocked only by an angular movement. The coupling is particularly adapted to be connected and disconnected by industrial robots in automated production sequences. The coupling transmits longitudinal forces and is radially locked.

    Abstract: A hose coupling wherein the end portion of a pipe is sealingly but separably connected with the end portion of a deformable hose by a tubular connector which has a first section sealingly fitted into the end portion of the pipe and a second section preferably sealingly attached to the end portion of the hose. The second section can abut against the end face of the end portion of the hose or it can surround or extend into such end portion. The connector carries one or more pivotable latching devices with pallets which engage a portion of the external surface of the end portion of the pipe or portions of surfaces bounding openings in the end portion of the pipe. A sealing element in the form of an O-ring or a sleeve is inserted between the internal surface of the end portion of the pipe and the external surface of the respective section of the connector to ensure that the seal between the connector and the pipe remains intact even if one of these parts moves axially relative to the other part.

  • Patent number: 4610468
    Abstract: A quick connect/quick disconnect coupling utilizes a retainer mounted between expanded ring portions of a tube. A sleeve is mounted over the retainer such that projecting leg portions from the retainer extend outwardly through openings in the sleeve. Upon assembly into a socket these outwardly projecting leg members engage a socket contact face to secure the coupling in the assembled position. To effect removal of the coupling the tube is displaced within the socket such that the retainer is displaced relative to the sleeve. As the retainer is displaced relative to the sleeve a compaction annulus portion of the sleeve acts to compress the projecting legs such that the tube with the attached retainer and sleeve may be removed from the socket to effect disconnection of the coupling.
