ABSTRACT:
The present disclosure describes a mechanism for positioning a pair of members in slip-free, adjustable, angular relationships. In accomplishing the foregoing, an assembly is provided which comprises a sphere and a pair of pivotally mounted jaw-like sections for engaging the latter. The inner surfaces of the sections have substantially the same radius of curvature as the sphere surface. Additionally, the sphere surface and the inner surfaces of the jaw-like sections are configured in respective interlocking patterns. Manipulation of the jaw-like sections allows the members to be placed in the desired angular position with respect to each other--which position is maintained by virtue of the aforementioned interlocking nature of the contiguous surfaces.
