machine. Some fillers of this type have 12 valves at one end of the 
tank and 20 at the other, so that a case of quarts and pints can be 
filled as desired, and both can be filled at the same time by having 
a man to operate each end of the machine. The capping machines 
cap one row of bottles or a whole case, depending on the type of 
machine, at one stroke of the lever. 
AUTOMATIC SINGLE-BOTTLE AND ROW FILLERS. 
So-called rotary fillers and cappers (fig. IT) have been introduced 
in recent years and are used extensively. This filler consists of a 
circular tank with valves similar to those of the other types of 
fillers. The bottles are removed from the cases and placed on a 
revolving carrier, which brings them under the valves of the tank. 
Each bottle is automatically raised as it comes under the valve and 
the milk flows into it. When the bottle has traveled the full revolu- 
tion of the tank it is automatically lowered and the valve closes. 
By revolving a full revolution the bottles have ample time to be 
filled. The bottles are then carried to the capper, which caps them 
automatically. With large machines of this type one man is required 
to take bottles out of the cases and feed them to the filler while 
another man removes the filled and capped bottles from the machine 
and returns them to the cases. There are several sizes of these
