Abstract
A V-coupling device for coupling coaxial annular flanges comprising at least two arcuate coupling members, a pivoting mechanism for pivotally and releasably coupling the coupling members at their first ends, and a tightening mechanism which includes an axially-oriented rotatable member for coupling the members together at their second ends and moving them radially inwardly. The tightening mechanism has a pair of camming surfaces that act upon cam follower surfaces integrally formed on the second ends of the arcuate coupling members. The camming surfaces move axially in response to rotation of the axially-oriented rotatable member. The coupling device is especially suited for installation in narrow annular space where tangentially-oriented tightening mechanisms are difficult to use.
