 cream separator, which had been manufactured from ISSl

 patents, the Keid separators A\ere patterned after the 

 Danish-Weston. Howe\cr, the,\' did not have much sale,

 the inner chaml)er and the 

 granules were con\'eycd in

 in still another direction. 

 This machine, it is said, was

 what Johansson claimed for 

 it, but the demand for 

 sweet cream butter was not 

 sufficiently great to make 

 the use of a butter ex- 

 tractor popular. The patents on Johansson's butter 

 extractor were purchased by the Vermont Farm Machine 

 Company of Ikllows P'alls, ^'ermout. Improvements 

 on this extractor, which was later modeled into a cream
