DAIRYMAID AND BLUEBELL 

 CREAM SEPARATORS. 



A Dairymaid or Bluebell cream separator will skim 

 so closely that there is scarcely a trace of butter fat left in the 

 skim-milk. Cleaaiag a Davymaid or Bhiebell is an easy job, 

 for all parts are accessible ; in fact these separators are unex- 

 celled, and no dairyman can profitably be without one. The 

 Dairymaid is a chain drive and the Bluebell is a gear drive 

 machine. Each machine is made in four sizes: 300, 400, 

 550 and 750 pounds capacity per hour. 



Although the Dairymaid and Bluebell are easily operated by 

 hand, some dairymen prefer a mechanical power. About 1/16 

 horse power is all that is required for 

 operating the largest size Dairymaid or 

 Bluebell separator. A Tom Thumb one 

 horse power air-cooled gasoline engine 



fs an ideal power for this purpose, as the engine is small, compact, 

 and reliable: or a two or three horse power I.H.C. vertical gasoline 

 engine may be used, which will also be found suitable for other 

 jobs. 



For full particulars concerninq the Dairyrnniil and Bluebell 

 cream separators and I .H .C . gasoline engines, see local dealer, 

 or write nearest general agent for catalog and booklet "Develop- 

 ment of the Cream Separator."
