  • Patent number: 8491017
    Abstract: An engagement section of a holder is engaged with a metal gasket, the gasket is received in a tubular section, and the tubular section is fitted in a step of a connection pipe. Another connection pipe is placed close to and facing the connection pipe that holds the gasket through the holder, and a center ring is installed surrounding the outer peripheries of the flanges. While a trapezoidal section having slopes which define both sides is inserted into a groove, center ring segments are closed to form a ring shape. A bolt which penetrates through a cutout of a segment is screwed into a threaded hole of the segment. The screwing of the bolt causes the amount of insertion of the trapezoidal section, which has slopes which define both sides, into the groove to be increased. As a result, the distance between flanges is reduced and the contact pressure of projections against both sides of the gasket is increased.

  • Patent number: 4418948
    Abstract: This invention relates to a method for coupling or joining pipes and tubes wherein an elastic force stored in said elastic coupling perpetually exerts a force that maintains a leak-proof connection between two ends of the pipes or tubes. Said elastic coupling comprises a plurality of the segments of an elastic ring having a cross section of annulus with an opening on the inward side of said elastic ring and a clamping collar of annular geometry with a groove on the inward side of said clamping ring, in which groove said plurality of the elastic ring segments are disposed in a confined fashion. The rims of two matching flanges built on each end of two pipes or tubes to be connected are received by said plurality of the elastic ring segments through said openings of the elastic ring segments.

  • Patent number: 4354522
    Abstract: In order to connect a stationary pipe to a movable pipe, a flexible connecting system includes a pipe section of rigid material fixed to one of said pipes, a pipe section of flexible material fixed to the other of said pipes and an interposed connecting pipe section of rigid material connected to said rigid section so as to be movable in one direction in reply to a tensile stress exerted onto said flexible section. Said connecting pipe section is divided into two parts releasably connected to one another by a quick-release connecting device, which, in case of tensile stress, collides with a stationary structure, which causes release of said device.

  • Patent number: 4341406
    Abstract: Pipe coupling of the type comprising two end fittings which can be fixed to two parts of the circuit to be connected and an open collar constituted by a plurality of articulated elements, with which are associated tensioning means, said elements cooperating with the end fittings to bring the latter into tightly sealed contact during the utilization of the tensioning means, wherein the collar has at least one C-shaped spring connecting each of the articulated elements and giving the collar a semi-rigid structure, there being a clearance in a direction longitudinal with respect to the spring between the latter and each of the articulated elements in order to prevent the transmission of the tightening forces to the spring.

  • Patent number: 4331012
    Abstract: Lockable meter retention rings for securing electric meters in meter boxes comprise an inner ring of multiple arcuate parts wherein the inner ring has spaced-apart inwardly extending flanges for holding the electric meter in the meter box and a steel outer ring which fits over and engages with the inner ring wherein the outer ring keeps the inner ring assembled. The outer ring has a lock enclosure which, together with a portion of the inner ring, defines an opening for receiving and retaining a barrel lock, the barrel lock securing the rings together. Bayonet and screw type engagements between the inner and outer rings are disclosed, with the barrel lock preventing relative rotation of the rings necessary to disengage them. Another form of engagement has a flange of the outer ring received by the inner ring, with the barrel lock securing the outer ring to the inner ring diametrically opposite the flanged engagement.

  • Patent number: 4225160
    Abstract: A clamp type connector for securing the ends of conduits having mating end flanges providing a fluid pressure tight connection, the connector comprising a plurality of clamp segments pivotally secured to each other in end-to-end relationship and having arcuate grooves of wedge-shaped cross-section. The conduit flanges are wedge-shaped in cross-section and adapted to be compressed tightly by the grooves of said clamp segments. The clamp segments are actuated by a double acting screw which is operable to clamp or unclamp the connection. The arcuate grooves in the clamp segments are provided with antifriction bearings, e.g. ball bearings, roller bearings or bushings, and the segments are provided with external stops limiting the movement of the individual segments in clamps having four or more segments. This clamp type connector is secured on one of the conduits and is removed or installed with such conduit.

  • Patent number: 4128921
    Abstract: A tension strap to be circumferentially positioned about a body to be tenned includes a strap member and a plurality of longitudinally movable tension blocks carried on the inside circumferential surface of the strap member for engaging the body. Means for maintaining each of the tension blocks in a defined predetermined position relative to the strap member is provided and includes at least one pin fixedly carried by either the tension block or the strap member and extending through a guideway in the other, and an elastic member such as a spring or elastomer acting on the pin of each tension block against longitudinal movement to predetermine its position relative to the strap member.
