Figs. 23 to 32 show the impro\'ement in the construction of hand and power driven sepa- rators. In some cases the supply tanks are lower, the mechanism is more simple, they run easier, they ha^'e greater capacity, and they are more efficient than they were fifteen years ago. As the dairy industry has grown, there has l)een a demand for a greater variation in the capacities of separators, in the hand machines from 80 to 100 pounds of whole milk an hour to 700 or 800 pounds an hour, and in the power sizes the variation is from the capacities of the hand separators to 10,000 pounds an hour. Thus it is seen that separators are made sufficiently snuill for a herd of only two or three cows, and some are so large F. Fig. 25. — A Simplex liaiul separator. At present there is a ^•ariation.
