DISTIILLING PPARATUS.

Specification of Letters Patent.

Patented heb. 1'?, 1914.

Application tiled December 28, 1911. Serial No. 668,224.

To all 'LU/mm it may concern Be it known that I, PHILIP lPUBLiGKER, a citizen of the. United States, residing at Philadelphia. in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Distilling pparatus, of which the following is a specification.

illy invention relates to improvements in distilling apparatus designed primarily for the recovery of alcohol and ether, and in which a suction pump is employed to draw the vapor rapidly through the system, and increase the etliciency of the apparatus, and secure the maximum of product in the minimuni space of time.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, asiwill be more fully hereinafter described and pointed out in the claim.

The accompanying drawing is a view in vertical section illustrating my improvements.

1I` 1, represent kettles in which a low grade alcohol is heated by steam coils 2 in the bottom of the kettles. rlhese steam coils are connected with any suitable source of steam supply, are located in the bottom of the kettles,` and through which a continuous supply of steam is had to heat the alcohol and cause it to become volatile. rlhe outlet pipes 3 of the kettles are each provided with cocks '-1. and are connected to a pipe 5. The

cocks 4 enable either or both of the kettles to be in open communication with pipe 5, which directs the vapor into a rectifying column G. This column 6 is connected by a pipe or goose neck 7 with a coil 8 in a condenser 9, and the lower end of the coil 8 is connected by a pipe 10 with the top of a receptacle 11. The top of this receptacle 11 is connected by a pipe 12 and goose neck 12a with the lower end o-f a coil 13v in a condenser 12, and the said coil at its lower end is connected to the top of the receptacle 15 by means of a pipe 16.

fk pipe 17 connects with the upper end of coil 13, and extends downwardly and'communicates with the top of the receptacle 18. rllhe pipe 17 between its highest point, and the receptacle 18, is provided with an elbow 19 connecting the said pipe with a suction pump 20, and this suction pump 2O is connected at its opposite side to a pipe 21 which 14E is maintained at a temperature approximating l? ahr.

When one or both of the cocks 4 are open suction pump 2O in operation, the vapor rising in the kettles 1 will be drawn upwardl)7 through the rectifying columns 6, thence into the coil 8 in condenser 9, which will cause the more 'volatile constituent to be condensed and fallinto the receptacle 11. This less volatilev constituent will be the alcohol, and the more volatile. constituent,

the ether and aldehyde, will be drawn up.

through pipe 12 into the coil 13 in condenser 14. rllhe more volatile constituent, namely,

the ether, will condense and fall into the receptacle 15, while the low grade aldehyde will be drawn through pipe 17 and droppedA down the said pipe into receptacle 18. ASuch vapor as may remain, will be drawn through the suction pump 20, and discharged through I pipe 21 into the water in receptacle 22, and,

be condensed therein, so that there will be no waste to the apparatus,

By connecting pipe 16 from tank 15 with the bottom of coil 13, any vapor which may form in tank 15 due to a rise in temperature and the action of the partial vacuum, will be condensed in the coil 13, and fall back into the receptacle, and this liquid will be prevented from passage down pipe 12 because of the goose neck 12a. ylthe coil 13 therefore operates to prevent any loss from tank 15, because it is interposed between the tank and the suction pump.

lit will be noted that by providing a plurality of kettles, that one kettle may be in communication with the apparatus, while the other kettle is cut off, and is being re charged. 'lhis enables the process to be carried on continuously, and by reason of the suction or partial vacuum caused throughout the system, the movement of the vapor and the condensation is more rapid, causing the apparatus to produce the maximum of output in the shortest possible space of time.

porized, a condenser located in a higher.

plane than the kettle, a' tank located in a lower plane than the condenser, a pipe connecting the kettle and the condenser, a second pipe connecting the condenser and the tank, a second' condenser having a 4submerged coil, a third pipe connecting the tank 4with the said coil inthe second-condenser adjacent its lower end and having a goose neck therein between the tank'and said lastmentioned condenser, a second tank, a pipe connecting the second tank with thelower end of said coil, a third tank, a pipe connecting the upper end of said coil with the third ,'tank, a suction pumpoommunicating with said last-mentioned p1pe,.a Water column,V

and a discharge pipe communicating with said pump and projecting into the Water column below the liquid level in the latter, Substantially as described.

In'testimony whereof' I have signed my name to this specica-tion in the presence of twov subscribing witnesses. I
