Description: |
| This seems to be the original patent for centrifugal dust separation, although it does not use a cyclonic separator. An ad in the May 1889 issue of "The Wood Worker" from the Chicago Exhaust & Blow Pipe Co. shows their Centrifugal Shaving and Dust Collector that uses this patent. |
