ABSTRACT:
A clamping apparatus for engaging a pair of abutting flanges from a pair of pipes has a pivot end of a first clamp portion pivotally joined to a pivot end of a second clamp portion by a pivot pin, such that the first and second clamp portions may be mutually rotated into an open attitude for enabling one of the first and second clamp portions to be placed in contact with the abutting flanges. The pivot pin then enables the first and second clamp portions to be alternately mutually rotated into a closed attitude for enabling the other of the first and second clamp portions to be placed in contact with the abutting flanges, the clamping portions thereby being drawn into mutually opposing positions so as to place a clamp end of each of the clamp portions in mutual proximity. The clamping apparatus further includes a rocking bolt and rocking nut hingbly attached to one clamp end to removably engage a rocking slot in an opposite clamp end so as to secure the clamp portions in the closed attitude. Finally, the clamping apparatus includes a spring wire that is engaged with the clamping portions such that when the clamping portions are only partially open, the spring wire biases the clamping portions towards the closed attitude, but when the clamping portions are opened substantially, the spring wire biases the clamping portions towards the open attitude.
