<p>A new saddle clamp comprises a U-bolt and a saddle strap providing complementary semicircular bights that meet in a diametric plane and embrace a cylindrical member to be clamped over the full 360 DEG of its circumference. The nuts employed with the U-bolt engage downwardly-inwardly inclined surfaces on the saddle strap to move the bolt legs together for uniform clamping sealing pressure around the cylindrical member as they are tightened thereon. It is found essential that the planes in which these nut-receiving surfaces lie do not intersect the cross-section of the cylindrical members being clamped since, if they do, rigid cylindrical members can act as reaction members to spread the legs apart and prevent the desired uniform sealing circumferential pressure.</p> |
