cable hook, by means of a pair 

 of pinions and a hand-wheel. 

 The ploughman can, during 

 work, adjust the regulator 

 rapidly and easily. 



The device for carrying the 

 plough back to the starting 

 point is ingenious. A small 

 wheel, carried by a block and 

 spindle, is, during the work, 

 hooked between the handles. 

 When the plough is out of the 

 ground the spindle is inserted 

 in a hole pierced sideways in 

 the framework. By tilting 

 the plough it is forced to rest 

 on that wheel, the implement 

 then running easily on the 

 three wheels. 



Working. Guyot's gin is 

 managed in the same way as 

 the Beauquesne fixed pulley. 

 The two anchors are fixed on 

 one side of the block, the gin 

 secured to the anchoring chain 

 opposite the first furrow to be 

 opened. As the work pro- 

 gresses the bar of the capstan 

 is slided along the anchoring 

 chain. The management of 

 the plough is the same as in 

 any other system. To facili- 

 tate the sliding of the gin-bar 

 along the anchoring chain, 

 this bar is tied to the gin by a 

 small piece of chain winding 

 round a small capstan. By 

 acting on the latter, the gin is 

 brought closer to the chain ; 

 the loosened bar is then easily 

 shifted. During the carrying 

 of the plough to the starting point a small brake is used to 

 regulate the unwinding.
