(c) "The peculiar construction that the saw teeth may run free, 

 whereby the necessary pressure and consequent friction of two cor- 

 responding edges cutting together as a pair of scissors, are entirely 

 avoided." 



The drawing, Fig. 5, shows this cutting apparatus. Attention is 

 called to the fact that the " saw teeth are sharp on their two sides." 

 The saw teeth in use to-day are sharp only on one side. Leaving the 

 teeth sharp on two sides makes a bevel on both sides of the knife sec- 

 tion. This is what is meant in the third claim just quoted. 



Every farmer's boy knows that a successful cutting device of to- 

 day is one that has " the friction of two corresponding edges cutting 

 together as a pair of scissors," the very element against which Hussey 

 so carefully provided. 



The construction of this cutting apparatus of Hussey's must have 

 been known to the compilers of the Protest. If they did not know 

 of this fatal defect in Hussey's cutting apparatus of 1833, they should 

 not be writing so positively on the subject; if they did know, then they 

 are deceiving their readers. 



That there may be no question of the drawing above (Fig. 5) cor- 

 rectly representing the Hussey cutting apparatus of 1833, I quote 

 from reissue letters patent No. 449, granted April 14, 1857, to Obed 

 Hussey: 



" In my original invention, viz. : the reaping machine patented by 

 me in 1833, the upper part of the guards was fastened to the lower 

 part both before and behind the blades, as represented at C C, and 

 the grass, straw, etc., which was not perfectly cut was forced in by
