Claims

1. MEANS FOR ADJUSTING THE RELATIVE POSITION BETWEEN TWO MEMBERS WHICH ARE CONNECTED TOGETHER IN ABUTTING RELATION BY A CAP SCREW THE SHANK AND HEAD OF WHICH ARE RECEIVED RESPECTIVELY IN MAIN AND RECESSED PORTIONS OF A COUNTERBOARD HOLE IN ONE OF SAID MEMBERS AND THE THREADED END OF SAID SCREW ENGAGING A THREADED HOLE IN THE OTHER OF SAID MEMBERS, SAID ADJSTING MEANS COMPRISING ONE OF A SET OF WASHERS, EACH OF SAID WASHERS HAVING A PAIR OF OPPOSED CIRCULAR FACES OF EQUAL DIAMETER ONE OF WHICH IS ENGAGEABLE WITH THE BOTTOM OF SAID RECESSED HOLE PORTION, A CYLINDRICAL EDGE SURFACE HAVING AN OUTSIDE DIAMETER CORRESPONDING TO THE INSIDE DIAMETER OF THE RECESSED PORTION OF SAID COUNTERBOARD HOLE AND AN APERTURE ADAPTED TO RECEIVE THE SHANK OF SAID SCREW, SAID COUNTERBOARD HOLE HAVING MAIN AND RECESSED PORTIONS WHOSE DIAMETERS ARE OVERSIZE RELATIVE TO THE SIZE OF THE SHANK AND HEAD RESPECTIVELY OF SAID CAP SCREW, THE CENTERS OF SAID APERTURES OF THE WASHERS OF SAID SET BEING OFFSET RELATIVE TO THE CENTER OF SAID CYLINDRICAL EDGE PORTION IN PROGRESSIVELY INCREASING AMOUNTS BETWEEN ZERO AND THE MAXIMUM RADIAL CLEARANCE BETWEEN SAID CAP SCREW SHANK AND THE MAIN PORTION OF SAID COUNTERBOARD HOLE, WHEREBY SAID ONE WASHER POSITIONS SAID SCREW IN THE COUNTERBOARD HOLE WITH THE AXIS OF THE SCREW ALIGNED WITH THE AXIS OF THE THREADED HOLE.
