GASOLINE POWER 341 



machinery may be started as soon as the buttermaker gets 

 into the creamery. 



Another matter to be considered in this connection is 

 the necessity of keeping up steam for cooling cream in 

 the afternoon, especially where much hand separator 

 cream is received. With gasoline power this is not neces- 

 sary. Also much cream is churned at too high a tempera- 

 ture because it must go into the churn in the morning 

 before there is enough steam to pump water. With a 

 gasoline engine cooling may be begun as soon as the 

 buttermaker enters the creamery in the morning. 



Other Advantages. It is evident also that a smaller 

 boiler would answer in a creamery where the machinery 

 is run with gasoline power. This would mean a saving 

 in both space and original cost of boiler. 



In case there is no special storage of water for fire 

 emergencies, a fire would be difficult to extinguish if it 

 occurred at a time when no steam pressure was available. 

 A gasoline engine can be started at any time and might 

 therefore be of much service in a fire emergency. 



Heating Water. This discussion would not be com- 

 plete without considering the possibilities of utilizing the 

 waste heat from the gasoline engine for heating the 

 necessary wash water and feed water for the boiler. 

 Statements from engineers and observation lead to the 

 belief that this could be done very satisfactorily with 

 gasoline engines. By sinking a water tank in the floor 

 of the engine room near the boiler and providing this 

 with a suitable muffle, most of the heat from the exhaust 

 could be recovered by running the exhaust pipe through 

 this tank. Water thus heated could be used for the 

 boiler and other purposes. For washing and cleaning
