 of deep vertical notches, into which fits a 

 notched oval bar or bolt pivoted in the clevis.

 Each rear arm of the clevis is made whole, 

 but becomes a half-section at the center or 

 front, where the two arms are pivoted together. 

 From the pivot each half tapers around the 

 curve, and runs out a little short of the other 



rear end. The bolt-hole is near the rear of 

 the evener, allowing the clevis to be uncoupled 

 when swung around. 



Claim. The clevis formed of the two hook- 

 shaped parts A B, pivoted to each other at 

 their bends, and the pin C, swiveled to the 

 long arm of one of the parts A B, and work-
