The Cream Separator. The cream separator is a ma- 

 chine for separating the cream from the milk. It does 



the work much better 

 and much more quickly 

 than it can be done by 

 allowing the cream to 

 rise in pans or in cans. 



The milk is turned 

 into a bowl which is ro- 

 tated rapidly. The milk 

 being heavier than the 

 cream, is thrown by the 

 revolving bowl to the 

 outside, and passes out 

 through a spout, while 

 the cream seeks the 

 center and passes out 

 through another spout. 

 The separator collects 

 many impurities from 

 the milk that even the 

 best strainers fail to catch. Separator cream is therefore 

 much purer than other cream.
