 of corn an hour. 



CORN SHELLERS 



316. Development. The earliest device used in the shelling 

 of Indian corn or maize was a simple iron bar placed across a 

 box and over which the ear of corn was rasped. The edge 

 of a shovel was often used in place of this bar. Another early 

 scheme was to drive the ear with a mallet through a hole just 

 large enough to let the cob pass through. 



Edmund Burke, Commissioner of Patents, in making his report 

 for the year 1848, states that two patents were granted on corn 

 shelters. He also states: "Corn shellers have usually been con- 

 structed in one of three modes. In the first the shelling is 

 performed on the periphery of a cylinder; in the second it is 

 done on the sides (one or both) of a wheel; and in the third 

 it is done by forcing, by means of a mallet or hammer, the cob. 

 surrounded by the corn, through a hole sufficiently large to 

 admit the cob only. The sides of this hole are called the 

 strippers and are often arranged in radial sectional pieces of 

 four, six, or eight each, acting concentrically against the corn 

 or cob by the force of a spring or substitute behind. 



"To this last kind of corn sheller there have been raised 

 several objections, the most prominent of which is that in the 

 opening of the radial sections by stripping the corn from the 

 cob the kernels often become entangled and wedged between 

 the radial sections and prevent some one or more of the sec- 

 tional pieces from acting upon the rows of corn to which it 

 may be opposite." 



Among the early American inventors, Clinton and Burrall are 

 the best known. The Burrall sheller was probably most popular. 

 It was made of iron, furnished with a flywheel to equalize 

 velocity, and was worked by one person while another fed it. 

 It discharged the corn at the bottom and the cob at the end. 

 Allen Wayne was the first man to make a two-hole sheller.

 eral types of corn sheller to-day outside of the ware-
