ABSTRACT:
An air ratchet adaptor having a slotted, semicylindrical handle with one end integrally formed into a flat, elongated, rectangular gear housing for transferring powered torque from an air ratchet which is commercially available to the general public in three-eighths inch or other size drive. The air ratchet can quickly and easily be inserted through the opening in the handle and snapped into its proper place. The handle includes the proper handle insert which provides adaptability to many different brands of air ratchets. The gear housing contains a driving gear, meshing idler gears, and a driven gear. The driving gear includes a square aperture for mating engagement with the square shank of the air ratchet head. The driven gear includes a hexagonal aperture to accept internal removable sockets. The internal removable sockets are provided for, to insure that the amount of work space needed to remove and install fasteners is kept to a minimum. The air ratchet adaptor connected with the air ratchet is suitable for installing and removing fasteners, and applying torque to such, in a limited work space wherein a stable, controlled one hand operation of a powered tool is needed.
