UNITED STATES PATENT GEEICE.

THOMSON MCGOWAN, OF MEREDITH, AND SAMUEL VAN SYCKEL, OF TITUSVILLE, PENNSYLVANIA.

IMPROVEMENT IN OIL-STILLS.

Specification forming part of Letters Patent No. 156,229, dated October 27, i874; application filed July 29, 1874.

To all whom it may concern Beit known that we, THoMsoN McGowAN, of Meredith, in the county of Venango and State of Pennsylvania, and SAMUEL VAN SYCKEL, of Titusville, in the county of Grawford and State of Pennsylvania, have invented certain Improvements in the Distillation of Hydrocarbon-Oils, of which the following is a specification l Our invention relates to certain improvements in stills for distilling liquid hydrocarbons and other similar substances; and it consists of a still having an elongated conical bottom extending down below the re, and connected with a receiver for collecting the tar and residuum formed during the process of distillation, as will be hereinafter described.

The still is also provided with a stirrer or agi-,

tator, to facilitate the removal of the tar or l residuum.

The drawing represents a sectional View of our improved still.

Arepresents the furnace invwhich` the still is set, Which may be ot' brick-work1 or other suitable material; and B represents the still. Said still is cylindricalV in its upper part, and the lower part or bottom is in the form of a i cone, extending downward through the bottom of the furnace, and connected toa receiver, F,

by a short pipe, M, provided with a stop-cock,

4 Within the lower part of the still is a stirrer, t

consisting of a series of blades, D D, arranged upon a revolving shaft, C, extending upward through the top of the still. S represents the fire-'chamber of the furnace, annular in shape,

-to stop the process for its removal.

and surrounding the bottom of the still. Said chamber communicates with the flue H, leading to the chimney, by means of a series of pipes or flues, E, extending through the still, as shown. The oil or hydrocarbon is admitted to the still by means ofa perforated coil, K, arranged in the upper or cylindrical part of the same, and the vapors are carried oliI to an ordinary condenser by means of the pipe or goose-neck I, extending from the upper part or top of the still.

' The operation of our improved still is as follows: The still being properly filled and the lire started in the furnace, the hydrocarbon will be vaporized, as usual. The vapors, as they are generated, will pass over through the goose-neck to the condenser, and the heavier portions, such as tar and residuum, which will not vaporize, will settle to the bottom, and may be drawn off into the receiver from tim to time, as may be desired.

.By the improved still above described a continuous distillation may be kept up, as the hydrocarbon can be admitted through the coiled pipe, as desired. As there is no collection of residuum in the same, it will not be necessary It is evident that all deposit or collection or residuum or coke upon the bottom ofthe still will be thus avoided, and all danger of burning or injurin g the still will be overcome.

Whatwe claim is- A still for distilling hydrocarbons, and other liquid similar substances, having au elongated bottom, extending through and below the lire in the furnace, and communicating with a receiver or pit, for collecting the tar and residuum, substantiallyas herein described.
