348 WORKING THS BUTTER 



On the interior of the combined churns and workers one 

 or more shelves are fastened to the sides of the churn; as the 

 churn revolves these shelves carry the butter and some of the 

 water up and drop them over the workers. 



In churns containing one worker only, as is the case with 

 the Perfection churn, the roller works against a shelf, the 

 butter being worked while passing between the roller and shelf.

In churns containing one or more sets of two rollers each, 

 roller works against roller, the butter being worked while pass- 

 ing between the rollers. To churns of this arrangement belong 

 the Disbrow, Dual, Simplex, Victor (4 rollers) and Wizard. 

 The Dual churn is equipped with an idler, a small, loose roller 

 on each side of the main workers. These idler rollers assist 

 in guiding the butter towards the workers and prevent it from 

 dropping down outside of the workers. In some churns (Dis- 

 brow and Victor) the workers travel with the drum of the churn, 

 while in other churns (Dual, Perfection, Simplex and Wizard) 

 the worker or workers are stationary and revolve only on their 

 own axis. In all churns excepting the Wizard, the churn revolves 

 while the workers are rotating. In the Wizard the churn makes 

 one turn, dropping the butter on the workers, then it auto- 

 matically stops and the workers start rotating. When the but- 

 ter has gone through the workers, the churn again revolves and 

 the operation is repeated.
