Abstract: AN IMPROVEMENT IN POWER WRENCHES FOR ROTATING POLYGONAL MEMBER, SUCH AS A NUT OR A BOLT. POWER MEANS, IN THE FORM OF AN AIR MOTOR OR THE LIKE, SUPPORT SPACED AND PARALLEL PLATE MEMBER EXTENDING FROM THE POWER MEANS AND HAVING ALIGNED APERTURES IN THE OUTWARD ENDS THEREOF. THE POWER MEANS ARE OPERABLE TO ROTATE A CAM MEMBER. A PULL ROD, DISPOSED BETWEEN THE PLATE MEMBERS, CARRIES A CAM FOLLOWER WHICH ENGAGES THE CAM MEMBER. ROTATION OF THE CAM MEMBER CAUSES STRAIGHT LINE MOVEMENT OF THE PULL ROD BETWEEN THE PLATE MEMBERS. ONE SIDE OF THE NUT OR BOLT, RECEIVED IN THE ALIGNED APERTURES IN THE PLATE MEMBERS, IS ENGAGED BY THE END OF THE PUSH ROD. A PULL ROD, ALSO DISPOSED BETWEEN THE PLATE MEMBERS, ENGAGES THE OPPOSITE SIDE OF THE NUT OR BOLT AND IS CONNECTED TO THE PUSH ROD BY A TRANSVERSE LINK. AS THE PUSH ROD IS MOVED IN ONE DIRECTION, THE LINK CAUSED THE PULL ROD TO MOVE IN THE OPPOSITE DIRECTION, THUS CLAMPING THE NUT OR BOLT BETWEEN THE PUSH ROD AND THE PULL ROD AND CAUSING ROTATION THEREOF. AS THE PUSH ROD IS MOVED IN THE OPPOSITE DIRECTION, THE PULL ROD, THROUGH THE LINK, IS RETURNED TO ITS ORIGINAL POSITION.
