ABSTRACT:
A threaded coupling chuck device for use with a female threaded tube, including a chuck body, adaptor means, probe means, seal means, and port means.
The body has an axis of rotation and shaft means for rotation, centered about said axis. Adaptor means are mounted on the body and have a threaded portion for engagement with the threaded tube to form a threaded coupling upon rotation of the internal portion of said body in a first direction about said axis. Probe means are slideably mounted in contact with the adaptor means and are positioned to align the respective threaded portions of said adaptor and said tube.
Seal means are included, and are positioned to prevent passage of fluid through the coupling. The seal includes a threaded annular portion of the adaptor means, which portion is adapted to expand into contact with the tube upon activation. The seal means includes piston means positioned to glide along the axis from a first position to a second position where the seal is activated. The adaptor means includes a plurality of pins parallel to the axis and positioned to contact the seal at one end to thereby expand the threaded portion of the seal. The probe has a shoulder means positioned to contact the pins upon movement of the piston to the second position.
Port means are provided to define a passage through the body, including an inlet for connecting to a source of fluid and in outlet through the adaptor means to the interior of the tube.
