I have had this for years and was wondering what they were really used for.
It say's DeLaval #200 Oil Purifier on the name plate, the patent dates are from 1907 to 1919
It still has the DeLaval electric motor on it and when you plug it in it runs the centrifuge at a pretty high RPM
It has three different spouts for something to come out, just not sure what.
It is heavy cast iron and pretty ornate.
Any idea's as to how it worked?

Thanks, Jerry
