Self-Aligning Coupler

Joint reduces assembly time and eliminates fumbling. Self-aligning coupler easy to use for people wearing heavy gloves or other restrictive clothing. Consists of two threaded sections, one with blade, other with slot - joined by threaded collar. Blade fits precisely in slot. Notch in blade engages pin in slot to form temporary attachment. Collar turned on continuous thread of joined sections to form tight, rigid joint. Designed for assembly of structures by astronauts in space suits, coupler used on Earth by firefighters wearing protective garments, technicians handling hazardous materials, and others working underwater or in other difficult environments.

Robotic Tool For Tightening And Cutting

Robot end effector designed for tightening tube couplers and for cutting tubes. Tool operable by simple movements and thus manipulated by technician wearing heavy protective clothing. Operates on principle of worm and pinion gear. Intended for use in building structures in space, end effector also used as hand tool for assembling truss structures for terrestrial buildings, tents, and oil rigs. Also used in place of pipe wrench in plumbing work.
