  
HISTORICAL SIGNIFICANCE OF THE SAVAGE ARMS EARLY ICE CREAM UNIT When World War I ended, Savage Arms had less need for the manufacture of guns and turned to the new commercial refrigeration industry which had just started to manufacture systems for preserving ice cream. This 1926 Savage Arms unit, OPERATING well in our museum, is one of two types of early hermetics in which the refrigerant did not come in contact with the motor windings. Since the late 1920's and early 1930's hermetic systems have been designed so that refrigerant was in contact with motor windings and through the years this has always been a problem and especially so today when there are so many new refrigerants. History shows that many of the problems with hermetics have been due to refrigerant caused winding problems which have developed through the years after the manufactured units have been produced. The Savage Arms compressor has no seal, no piston or internal moving parts. Instead, a mercury column compresses the refrigerant gas as the entire unit rotates. This compressor is unlike any made today in that it is a hermetic, and yet refrigerant does not come in contact with motor windings. Could this design be modified for the future?
