Oil February 4, 185 1, a United States patent was granted to Sydney 

 S. Hurl but that merits attention in that it elevated the swath of cut 

 grain over the main supporting wheel, and because it was one of the early 

 attempts to produce gavels of uniform size. The machine was provided 

 with reciprocating cutters and an endless conveyor. Upon the latter 

 the cut grain was laid by the reel as the machine advanced. The mov- 

 ing apron conveyed the swath beneath flexible holding-rods that pre- 

 vented any disturbance during its ascent and then deposited it in a 

 poised receptacle. This receptacle was divided into three cells by radial 

 partitions. When a sufficient quantity of grain was received to effect a 

 counterpoise, the receptacle moved downward sufficiently to disengage 

 his locking device, when the weight of the accumulated mass caused the 

 receptacle thus set free to turn a ihinl of a rL-volution and deposit its 

 contents upon the ground. 



Woodward had shown, in 1845, the possibility of producing gavels of 

 somewhat uniform size when aided, but the Hurlbut device was prefer- 

 able because of the fact that it divided the continuously moving swath 

 of grain into gavels of substantially uniform size, and that automatically. 

 It was probably the first attempt to accomplish the result.
