 row to the other. 



3. The combination of the thrusting-levers 

 i i, for operating the chopper with the spring- 

 catches q and their holding and releasing cords 

 </, whereby the action of the levers is arrested, 

 and they are held up out of the range of their 

 operating pins. 



4. The combination of the thrusting-levers 

 it, for operating the chopper, with the vertical 

 guide-frame n n and the springs k k, as de-

 across the rows. The shape of the runners 



permits the hoes to strike the top of the ridges 

 and raises them over the furrows. 



Claim. 1. The machine herein described for 

 thinning or spacing root and other crops, con- 

 sisting of a series of hoe blades F, arranged and 

 operating in combination with guides A 1 A 2 , 

 substantially as herein before set forth. 



2. In machines for thinning or spacing root 

 and other crops, the frames A, consisting of 

 the trough shaped guides A 1 A 2 connecting 

 bar A 3 and hoe blade F, coupled together in

The front end of the chopper shaft rests in 

 •a sliding bar operated by a lever and crank, 

 which gives vertical and lateral adjustment to 

 the hoes. The rear boxes, of the two shafts 

 are pivoted crosswise to each, which allows 

 the described movement. 



Claim. 1. The combination, with a revolv- 

 ing hoe, of a carrying head block, / capable 

 of lateral adjustment to keep the hoe directly 

 over the cotton ridge as the machine moves 

 forward. 



2. The combination with a revolving hoe, 

 of a carrying head block / capable of both ver- 

 tical and lateral adjustment for the purpose 

 set forth. 



3. The combination of the head block /for 

 carrying the hoe shaft, and capable of vertical 

 and lateral adjustment, with a lifting or crank- 

 ed rod n o o , and the lifting lever /, whereby 

 the hoe is raised and lowered, directly by the 

 cranked rod. 



4. The combination of a revolving hoe hav- 

 ing a capacity for vertical and horizontal ad- 

 justment, with a combined double bearing, uv 

 and the driving shaft g, whereby the gearing 

 end of the hoe shaft and its bearing box may 

 have a compound movement to conform to 

 the. adjustment of the hoe.
