A vibrating frame is connected by a draft- 

 rod to the main frame. Vertical shafts, carry- 

 ing horizontal knives, are pivoted on the 

 former, and their bent arms meet above the 

 frame. A forked rod extends forward from 

 the arms, having a roller, which travels in the 

 channeled edge of a wheel, revolving with the 

 main axle. This wheel has irregular project- 

 ions, which operate the shafts, to open the cut- 

 ting knives and leave hills. A spring throws 

 them back to position. 



Claim. 1. The combination of the horizon- 

 tal knives K, the vertical shafts L, having in- 

 wardly projecting arms formed upon their up- 

 per ends, and the spring R with each other
