O. H. HALL AND JOHN ELLIS, OF NEV YORK, N. Y.

IMPROVED DISTILLING APPARATUS.

Specification forming part of Letters Patent N0. 58,813, dated October 16, 1566.

To all whom it may concern:

Beit known that we, O. H. HALL and JOHN ELLIS, ot' the city,vcounty, and State of New York, have invented a new and Improved Distilling Apparatus, and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompan yin g drawings, forming part of this specification, in which- Figure lv represents a longitudinal vertical section of this invention. Fig. 2 is a trans verse vertical section of thc same. Fig. 3 isa plan or top view of the saine.

Similar letters of reference indicate like parts.

This apparatus is designed particularly for distilling or refining petroleum-oil, but may be employed in the distillation of turpentine and volatile oils of any other description.

It consists chieiiy of two retorts or stills, A and B, one placed over the other, and then upon arch O and furnace D, with flue E between and connecting arch O with chimney E. It is provided with a supply-pipe, a, connecting-pipe b, discharge-pipe c, and vapor-passages G and G. lt is also provided with two condensing-chambers, H and H. The con- (lensing-chamber H is connected with retorts A and B by the vapor-passages G and G, and it contains a coiled tube, c, which extends through its entire length. The condensingchamber H is placed above the chamber H, and is connected with the same by passage I.

The chamber H contains a series of tubes, f, which extend longitudinally.through the same and pass into water-chamber J, as is clearly shown :in Fig. 1.

Our apparatus is also provided with a residuum-receiver, L, which consists of an open cylindrical tank, into which enters the residuunrpipe IV and the water-pipe g, and from which issues the wastewater pipe m and oilpipe a.

The operation is as follows: Into the retort A the crude oil or other liquid to be distilled is iirst allowed to enter, so as to cover the bottom of the same in a thin stratum. The oil which is not distilled in the retortAiiows into retort B through connecting-pipe b, and covers the bottom of said retort also in a thin stratum.

tend.

The oilor other liquid enters retort A in a continuous stream through the tube a, and when the bottom of said retort becomes covered with a stratum of oil of the desired depth it overflows into retort B through connectingpipe b, which extends up through the bottom ot' retort A near the opposite end at which the oil enters, t'or the purpose above mentioned, and enters the top of retort B near its back The residuum of the oil or other liquid being distilled, atter passing over the heated bottom ot1 retorts A and B, is discharged through the pipe O.

C is the arch upon which retort B is placed, at the front end of which furnaceD is located, in which a tire is made to produce the distillation ofthe oil or other liquid within retorts A and B. E is a iiue which returns the heat under retort A and commences distillation within the same. F is the chimney through which the products of combustion tinally escape.

H is a condensing-chainber, into one end ot' which the vapor ot' the oil or other liquid being distilled passes and becomes partially condensed into liquid again.

G is the pipe which passes the vapors from retort B into said chamber, and G is the pipe which passes them from retort A into condensing-chamber H, near the same end.

Oondensing -chamber H contains a coiled tube, @,which extends its'entire length, through which water is allowed to run, in order to e'ect the partial condensation of the vapor within said chamber.

H is another condensingchamber, placed above chamber H, and connected with the same by passage I, through which the light vapors which do not condense in chamber H pass, to become finally condensed in chamber H.

Through chamber H extend tubes f, which connect at each end with water-chamber J and J, respectively, through which cold water en ters at pipe o, and, passing through said tubes and chambers, completes the condensation of the vapors which pass into said chamber.

p is the pipe through which the water passes from water chamber J into coiled tube e, through which it passes, and is finally discharged through pipe I into residuum-tank L. W is the pipe through which the residuum is na-lly discharged from retort B into receiver L, said pipe being bent down so as to discharge the residuum into said receiver nearits bottom, where it comes in contact with the water, with which it is partially illed from water-pipe I, when it becomes cooled and rises to the top of the water, and runs off through pipe S at an altitude corresponding to the depth of the stratum of oil Within retort B, while the water is discharged from receiver L through bent pipe u, arranged so that it receives the Water to be discharged near the bottom of receiver L, and discharges the same from the receiver at an altitude slightly lower than the point at which the residuuln is discharged, thus completing the separat-ion ofthe water from the oily products effectually, and at the same time keeping the surface of the oil within the receiver L, and consequently within retort B, of a uniform height,l without exposing the same to the chances of spontaneous combustion in consequence of' its exposure to the atmosphere while unduly heated, it being sufficiently cooled during its passage through the stratum of water which always.

exists in the lower part of receiver L.

k is the pipe through which the products of condensation from the chamber H are drawn ofi". l is the pipe through which the light oils are drawn from chamber H. V is the pipe through which the non-condensible gases escape from chamber H.

Z and Z are tubes which pass through water-chambers J ,and J longitudinally, and serve to give an additional passage for the vapors to enter and escape from chamber H'.

By these means a continuous distillation is effected and the products of distillation are separated according to their specitic gravity without being compelled to interrupt the operation and Without danger of a spontaneous combustion.

Vlie claim as new and desire to secure by Letters Patent- 1. The arrangement of two or more retorts, A B,through which the liquid to be distilled passes in a thin stratum, substantially as and for the purpose described.

2. The iiues C E, in combination with the retorts A B and fireplace D, constructed and operating substantially as and for the purpose set forth.

3. The pipes G G', leading` from the retorts A B to one and the same condensing-chamber, H, substantially as and for the purpose described. y

4. The inclined condensingchainber H', in combination with the inclined condensingchamber H and retorts A B, constructed and operating substantially as and for the purpose set forth.

5. The residuum-tank L with pipes XV u s, in combination with one or more retorts, constructed and operating substantially as an'd for the purpose described.

6. Passing the vapors through a closed vessel containing a pipeor pipes through which cold water passes, said vessel being provided with one or more discharge-pipes to draw out the condensed liquid of any desired gravity, substantially as set forth.
