UNITED STATES PATENT OFFICE.

GERARD CRANE, OF SALAMANOA, NEW YORK.

OI L-STl LL.

SPECIFICATION forming part of Letters Patent No. 231,280, dated August 17, 1880.

Application filed May 13, 1880.

To all whom it may concern Be it known that I, GERARD CRANE, of Salamanca, in the county of Gattaraugus and State of New York, have invented a new and useful Improvement in Oil-Stills, of which the following is a specification.

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.

The accompanying drawing represents a vertical section of an apparatus embodying my improvement.

The main still consists of a tank, Aywhich may be of any suitable shape and dimensions, but is here shown as of quadrangular form. Within this tank, near the top, is a smaller tank, B, arranged in an inclined position.

0 is a tank containing crude oil, and from this tank the oil is forced in any suitable manner.

A pipe, D, leads from the tank 0 in an upwardly-inclined direction to a point near one end of the still A, thence into said still and upwardly toward the opposite end thereof, thence upward vertically, and thence upward diagonally again to a point near the first-mentioned end of the still A, at which point the pipe D enters the still B near its lowest end. This lowest end of the still B may be provided with a gage-pipe, I), to show the height of the oil therein at any time.

The highest end of the still B is provided wlth a pipe, E, leading to a still, G, on the top of the main still A, which still G is also inclined, but in an opposite direction to that of the still B.

From the highest end of the still G a pipe, H, leads upward, then horizontally, and then downward to a condenser, J, said pipe H belng provided with stop-cocks h.

(No model.)

The top of the still A is provided with pipes P, which may be furnished with stop-cocks.

From the highest end of the still G a pipe, K, leads downward and into the main still A.

The operation is as follows The oil is forced from the tank 0 up through the pipe D and into the interior still, B, and from thence through the pipe E to the still G, where the heat applied to the tank A is sufficient to cause the oil to give off the benzine, naphtha, and other more volatile products of distillation, which pass from thence through the pipe H to the condenser J. The stop-cocks h in the pipe II are for the purpose of regulating the flow of benzine and other volatile products. When they are heaviest the cooks are turned so as to send them more directly to the condenser, as will readily be understood on refer' ring to the drawing. As the more volatile products are given oil the oil passes from the still G down through the pipe K to the main still A, where it goes through the ordinary process of distillation. As the crude oil rises through the pipe D from the tank 0 the water, being heavier than oil, will pass off through tlIie branch pipe L and be received in the tank 1\/ Having thus described my invention, I claim as new and desire to secure by Letters latent 1. The combination, with the main still A and interior still, B, of the crude-oil tank 0, connected by the pipe D with the interior still, as shown and described, for the purpose specifled.

2. The combination, with the main still A and interior still, B, of the exterior still, G, pipe E, pipe H, and condenser J, as herein shown and described.

3. In an oil-still, the combination, with main still A and inclined exterior still, G, of the connecting-pipe K, commencing at the highest end of the bottom of said exterior still and extending into the inside of main still, as shown and described.
