DESCRIPTION. 



Tho present corn shocker was invented in ISSS, and a machine was 

 constructed that year by A. N. Iladley. It was buih with a frame 

 mounted on two w^heels the same as the corn binder, and consisted of a 

 corn-o-athering; device — revolvino; reels on vertical standards, the 

 upper bearings of which were arranged for adjustment laterally, and 

 fore and aft. It had as a cutting device two circular rotating cutters 

 operating against each other and cutting the corn as the machine 

 advanced toward it. 

 Behind the cutting 

 device was a circular 

 rotating table 5 feet 

 in diameter, upon 

 which the corn was 

 collected vertically to 

 form a shock. On 

 this table were sev- 

 eral radial ribs, which 

 aided in revolving the 

 standing corn. In the 

 center of this table 

 was a rotating shock- 

 forming standard bav- 

 in g radial arms, 

 around which the corn 

 was collected. A re- 

 volving crane w a s 

 mounted on the frame 

 and a rope and pulle}^ 

 attached above the 

 shock by which it 

 could be lifted from 

 the platform and de- 

 posited on the ground. 



In 1893 a shocker 

 was constructed by J. M. Shively, similar in principle but somewhat 

 departing in its construction from the Hadley shocker in that the 

 cutting apparatus and the dividers were like those of the corn har- 

 vester, and the retaining wall surrounding the shock-forming table 

 was somewhat higher than that on the Hadley shocker. 



The present form of shocker (fig. 17) consists essentially of the 

 dividers already described in connection with the corn binder, a revolv- 

 ing table for assembling the shock, and a crane for removing it. The 

 knives and fly-wheel attachment for cutting the stalks, and the
