BULLETIN 849, U. S. DEPARTMENT OF AGRICULTURE. 



a platform or from chutes which are placed so high that they come 

 even with the floor of the delivery wagon, very little lifting is re- 

 quired. 



The figures in Table 3 also indicate that if a platform is used the 

 system of trucking the milk from the storage room is much less eco- 

 nomical as to time and labor than sending the milk out on con- 

 veyers. At a small plant loading only a few wagons the use of con- 

 veyers may not be practicable. One or two men besides the driver 

 can handle the work, while in using a conveyer system more men may 

 be necessary, although the time consumed would be less. 



Fig. 6. — Loading delivery wagons at plant using system E. (The second chute was not 

 in use at the time the photograph was taken.) An average of 34.3 wagons per hour 

 were loaded at the three plants using this system. The average time required to load 

 one wagon varied from 1.5 to 2.3 minutes. 



The table also indicates that considerable time may be saved by 

 using a conveyer rather than by loading the wagons direct from the 

 storage room through one door or chute ; though this means but little 

 if only a few wagons are to be loaded. The hours of labor per wagon 

 were not very different with the two systems, while the time per 

 wagon ■ was nearly three times as great with system D as with the 

 platform-and-conveyer system. 



At plants where two or more chutes from the refrigerator room 

 are used, roller conveyers generally carry the milk from the rear of 

 the room to the door, and usually one class of goods is put out at each 

 door. For example, quarts of milk will be put out at door No. 1, 

 pints at No. 2, and cream, etc., at door No. 3. As many wagons can
