DISTILLING APPAKATUS, Stokes Automatic, steam heated. These stills have two features which 

 render them unusually effective in the production of pure distilled water. First, they utilize 

 the heat generated in the still to preheat the incoming water to the boiling point, thus requir- 

 ing a very small quantity of live steam to keep them in operation after once started. Second, 

 by preheating the feed water before it enters the distilling chamber ammonia and other gases 

 are liberated and permitted to escape into the atmosphere through an opening in the condenser 

 provided for this purpose, preventing their reabsorption by the distilled water. The distilling 

 chamber and condensing cylinder are of cast iron galvanized to withstand corrosion. The con- 

 denser tubes are brass, heavily tinned inside and out. These stills may readily be flushed for 

 cleaning by means of a valve connecting with the drain, or the copper lid may be removed and 

 the inner chamber scrubbed. They are self-contained, requiring only the two connections for 

 steam and water, and are shipped ready to set up. Capacities are based on a steam pressure 

 of at least 20 pounds.
