ABSTRACT:
The loading and locking mechanism includes a first cylindrical member with means defining a circumferential groove therein having a first surface of revolution disposed at an angle with the axis of the first cylindrical member. Cooperating with the first cylindrical member is a second cylindrical member having an axial opening sized to accommodate the first cylindrical member and an inside surface groove having a second surface of revolution disposed at an angle with the axis of the second cylindrical member. A continuous ellipsoidal spring having canted coils is disposed in both first and second cylindrical member grooves for forcing the first and second surfaces of revolution away from one another to cause axial loading between the first and second cylindrical members. Additional locking surfaces may be provided each of the first and second grooves which are disposed generally perpendicular to the first and second cylindrical member axis.
