ABSTRACT:
An adjustable clevis includes a pair of opposed, spaced clevis members each having one end thereof secured to a cylindrical body. The body may consist of a threaded bore or a threaded stud to permit coupling with the male or female components of a linkage or the like. The clevis members are formed by passing a sheet of metal through a progressive die which shears and coins blanks into a configuration consisting of an outer perforated ear and an arcuate base having an inner curved surface which conformingly engages the body and is off-set relative to the ear.
