Abstract
An adjustable pass-through joint comprising a main joint body having a first bore longitudinally therethrough, a second bore orthogonally intersecting said first bore, a third bore intersecting said second bore and a fourth bore intersecting said second bore, a cylindrical locking member rotatably mounted within said second bore and having a partially-threaded opening in line with said first bore, a threaded rod slideably installed within said joint body, and a shaft insertable within said third bore which, by wedging itself between one side of said third bore and a cut-away surface on said locking member, retains said cylindrical member in an angular position where the threads of said partially-threaded opening are locked with the threads of said rod, preventing longitudinal movement of said rod within said joint body. When said shaft is removed from said joint body, a compressed spring mounted within said fourth bore applies torque to a notch cut in the cylindrical surface of said locking member, causing it to rotate to an angular position where the threads of said partially-threaded opening are disengaged from the threads of said rod, thus allowing longitudinal movement of said rod within said joint body. A cam may be cut on said shaft in a position where it will act on said cut-away surface so that the frictional force between the threads of said locking member and those of said rod varies as said shaft is rotated.
