DISTRIBUTION OF SKIil-ilILK AND BUTTERMILK. 



In recent years nuich attention has been given to the 

 problem of skim-milk distribution at creameries. The old 

 way of weighing on a common pair of scales is too slow 

 and tedious. Efforts to improve upon this method of 

 weighing have resulted in bringing upon the market vari- 

 ous kinds of automatic weighing and measuring devices 

 such as our skim-milk weighers and check pumps. With 

 the skim-milk weigher the patron drops into the machine 

 a check corresponding to the amount of milk delivered, 

 and the amount of skim-milk called for by the check is 

 weighed or measured out automatically. In the case of 

 the check pump the operation is somewhat dift'erent. A 

 check is dropped into the pump and, instead of flowing 

 out, the amount of skim-milk called for by the check is 

 pumped out. 



Some of these skim-milk weighers are giving good satis- 

 faction when properly handled. But at least fifty per cent 

 of the creameries are still adhering to the old methods of 

 weighing on a common platform scales which, though 

 tedious, is still perhaps the most accurate method. 



Attention is here called to an automatic valve closing 

 arrangement, shown in Fig. 34, which reduces the labor 

 of weighing on a platform scales at least fift\' per cent. 

 A is a common pair of scales, B an ordinarv receiving can 

 with a two inch valve instead of a faucet, and C a device 

 which closes the inlet valve, D, when the proper amount 

 of skim-milk has nm into the can. 



It will be seen that one end of the rod, C, is attached to
