Abstract
A split coupling of clam-shell configuration applied laterally over abutted ends of confronting tube sections with bead-over-wire reinforcement engaged with opposed shoulders of separable body members, and having depressible ring and abutment seals molded into the separable body members hinged for abutment a diametrical axially disposed plane coincidental with the axis of the body members when closed over said confronting tube sections by link and latch means, all basic structural members operating in tension and shear connections multiplied for greater strength and for uniform load distribution, said ring seals being scarfed for circumferential continuity, and there being an electrical bond between the coupling and said confronting tube sections.
Claims21
A split coupling of clam-shell configuration for sealed lateral application over the radially beaded open end of a tube section, and including;
- a pair of segmental body members separable at a diametrically disposed plane coincidental with a central longitudinal axis and at which plane opposite side faces of the body members have abutted interface engagement,
- a longitudinal bore concentric with said axis and extending through the pair of body members to open at one end thereof for the reception of an end portion of the tube section,
- a counterbore in the body members and of greater diameter than the longitudinal bore to receive the radial tube section bead and extending to an inwardly disposed shoulder engageable with the radial tube section bead thereby to prevent separation of the tube section therefrom,
- one side of the body members being joined by hinge means,
- the other side of the body members being releasably joined by latch means comprised of longitudinally disposed concaved seats formed in radial enlargements outward of the abutted interface engagement at said other side of the body members respectively, a link rotatively carried by one body member and contiguously engageable over the radial enlargements of said body members, and a toggle clamp rotatively carried by the link and releasably engaged with a seat in said other body member,
- a circumferential seal carried at said one end of the body members and comprised of depressible segments projecting radially inward from the bore of each body member to engage with the outer diameter wall of a tube section extending therethrough, said seal segments having male and female formation and at least one of which extends circumferentially from the abutted side interface engagement of said body members for reception one within the other,
- and a longitudinal seal carried at each abutted interface engagement of the opposite side faces of said body members and comprised of a depressible section projecting from the side face of one body member to engage with the side face of the other body member at said abutted interface engagement thereof and extending from the circumferential seal segments at the one end of the body members.
A split coupling of clam-shell configuration for sealed lateral application over the radially beaded open ends of confronting tube sections, and including:
- a pair of segmental body members separable at a diametrically disposed plane coincidental with a central longitudinal axis and at which plane opposite side faces of the body members have abutted interface engagement,
- a longitudinal bore concentric with said axis and extending through the pair of body members to open at opposite ends thereof for the reception of confronting end portions of the tube sections,
- a counterbore intermediate the opposite ends of the body members and of greater diameter than the longitudinal bore to receive the radial tube section beads and extending between inwardly opposed shoulders engageable with the radial tube section beads thereby to prevent separation of the confronting tube sections,
- one side of the body members being joined by hinge means,
- the other side of the body members being releasably joined by latch means comprised of longitudinally disposed concaved seats formed in radial enlargements outward of the abutted interface engagement at said other side of the body members respectively, a link rotatively carried by one body member and contiguously engageable over the radial enlargements of said body members, and a toggle clamp carried by the link and releasably engaged with the seat in the other body member,
- a circumferential seal carried at each opposite end of the body members and comprised of depressible segments projecting radially inward from the bore of each body member to engage with the outer diameter wall of a tube section extending therethrough, said seal segments having male and female formations and at least one of which extends circumferentially from the abutted side interface engagement of said body members for reception one within the other,
- and a longitudinal seal carried at each abutted interface engagement of the opposite side faces of said body members and comprised of a depressible section projecting from the side face of one body member to engage with the side face of the other body member at said abutted interface engagement thereof and extending between the circumferential seals at opposite ends of the body members.
