lift the cooler box cover, lift the 10- 

 gallon can of milk, and place it in 

 the water. If the recommendations 

 for carrying milk from the stables 

 are followed, two 10-gallon cans will 

 be filled in three trips to the milk 

 house. On the next trip, the strain- 

 ers would be moved to the next empty 

 cans in line and the covers secured on 

 the filled cans. At this time or on 

 the next trip to the milk house, the 

 two cans can be placed in the cooler 

 in .2 man minutes. The task is easier 

 where the cooler tank is at a lower 

 level and thus the can has to be 

 raised only a few inches from the 

 floor. The displacement of water 

 eases the weight in lowering the can 

 to the bottom. Where the cooler is 



on the same floor level as the milk 

 house a raised platform with steps 

 is used, but more time and greater 

 physical burden are involved. 



None of the operators had mechan- 

 ical can lifters and most of them 

 were not interested because they 

 thought more time would be needed. 

 A mechanical lifter should no doubt 

 be installed where young boys or old- 

 er men do this chore. If this task is 

 done during milking by the milker, it 

 is important to do it quickly so that 

 the man is back with the cows as soon 

 as possible. 



The truck driver usually takes the 

 cans out of the cooler and this has 

 not been considered as a part of the 

 farmer's chore work. If the cooler
