Offset driver for threaded fasteners

Abstract

Abstract THIS INVENTION RELATES TO A DRIVER FOR SETTING THREADED FASTENERS IN HEIGHT-LIMITED ENVIRONMENTS. THE DRIVING PORTION OF THE DEVICE NEED NOT BE MOVED AXIALLY, BUT MAY BE APPLIED TO THE FASTENER IT IS TO SET BY LATERAL MOVEMENTS, THEREBY SIGNIFICANTLY REDUCING HEIGHT AND MANIPULATIONS. IT INCLUDES A BODY TO WHICH ARE MOUNTED A POWER SHAFT AND A LATERALLY EXTENDING GEAR TRAIN DRIVEN BY THE POWER SHAFT WHICH GEAR TRAIN TERMINATES IN A PAIR OF BRANCHES. EACH BRANCH INCLUDES A DRIVE GEAR THAT IS ENGAGED TO A DRIVING SOCKET. THE SOCKET AND THE BODY HAVE ALIGNABLE SLOTS AND THE ANGULAR EXTENT OF THE SLOT AT THE PERIPHERY IS LESS THAN THE ANGULAR SPACING OF THE DRIVING GEARS AROUND THE CENTER OF ROTATION OF THE SOCKET WHEREBY THE SOCKET IS ALWAYS DRIVEN BY AT LEAST ONE OF THE BRANCHES. MEANS IS PROVIDED FOR TURNING THE SOCKET INDEPENDENTLY OF FINGER ACTURATION SO THAT THE SOCKET AND BODY SLOTS CAN BE ALIGNED, AND DETENT MEANS IS PROVIDED TO HOLD THEM ALIGNED.
