Description: |
| Claim:
My invention consists in a novel arrangement of a small still within a larger or main still and another small still outside of said main still, and a novel combination and arrangement of devices employed in connection therewith, whereby the process of distilling the oil is facilitated and hastened by enabling the oil to give off the more volatile products of distillation at the same time that the heavier products are being given off, and by means of the same fire for all of said stills. |
