Les fertniers, qui les essayerent, trouverent qu'elles ne travail leraient 

 pas avec succes ou avec profit, ce qui semble avoir ete leur sort jusqu'en 

 1845 quand un second brevet fut pris pour des perfectionnements 

 apportes a la premiere, et meme alors, quoique la machine, ainsi per- 

 fectionnee, etait consideree de plus de valeur que la primitive, cepen- 

 dant, par suite des difficultes de rateler le g^rain coupe de la plate- 

 forme, elle n'alla pas en operation g-enerale et satisfaisante avant 

 I'epoque ou un arrangement pour le sieg-e du rateleur fut introduit, 

 arrangement qui fut brevete en 1847."

 DANFORD'S MOWING MACHINE. 



On September 17, 1850, a United States patent was granted to E. 

 Danford for improvement in mowing machines. A main frame was car- 

 ried upon a main supporting wheel, and in order to effect the height of 

 cut required, was adjustable from the supporting wheel. From the main 

 frame extended the cutting apparatus, which, when the machine was 

 used as a reaper, was supported upon a small wheel. Motion was 

 imparted to the cutting apparatus by a suitable gearing. The cutter-bar 

 was hollowed, and within it moved two cutters consisting of blades of 

 the Hussey type, suitably secured to a bar. These knives were given 

 movement by cranks formed in a single shaft. The cutting of the grass 

 took place between these blades when approaching each other. The 

 tongue was so pivoted to the main frame that its position might be regu- 

 lated at will. 



These machines went into extensive use on the prairies of Illinois, 

 U. S. A., where they made excellent records. The juices of the grasses 

 and plants affected the operation of the machine so seriously, by adher- 

 ing to the blades and forcing them apart, that the cutting apparatus of 

 Mr. Hussey was soon adopted.
