DIS TILLING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 780,536, dated January 24, 1905.

Application filed February 26, 1904: Serial No. 195,447.

To all whom it may concern:

Be itknown that I, HENRY A. STEBER, a citizen of the United States, residing at Utica, in the'coun'ty of Oneida and State of New York,

have invented certain new and useful Improvements-in Distilling Apparatus; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in distilling apparatus.

The object of the invention is to provide a still, a peculiar condenser therefor, and means assembled with said still and condenser for the utilization of ,a portion of the discharged cooling liquids from said condenser in the still for forming vapors which are to be passed into the condensing-chamber of the condenser.

Another object of the invention is the construction of a condenser with the inner cooling-casing of such construction and arrangement that when placed in an assembled position with the other compartments of the condenser it will form a condensing-chamber which has a decreasing area toward the lower discharge end thereof.

A still further object is to provide eflicient means which are simple in construction for' complete apparatus, showing'the condenser in transverse section and the discharge-receptacle and the still in side elevation. Fig. 2 is a fragmentary view of the sectional outer casing, showing the locking means for retaining the sections in an assembled position.

Referring to the drawings by referencenumerals, 1 designates a still which is preferably formed cylindrical in shape and which is provided with an integral annular flange 2. A removable annular top 3 is secured in an assembled position with the body of the still by means of a plurality of removable thumbscrews or similar devices 4. In order to form atight joint between theflanges 2 and 3, a suitable packing 5 is interposed between the meeting edges of the flange portions of said members. Assembled with said still 1 and preferably secured to the top portion thereof is a horizontal communicating casing 6, which is adapted to conduct the vaporized liquids to the condensing-chamber 7 of the condenser. The conducting means 6 may be of any preferred type and can be formed integrally with the top of the still or removably secured thereto.

In the construction of a completed apparatus I preferably employ a suitable burner 8 for the purpose of vaporizing the liquids contained within the still when the apparatus is in operation.

In the construction of the improved condenser I employ a cylindrical sectional outer casing 9, which comprises in its construction a lower section 10 and an upper sectionll. The lower section 10 of the casing 9 is provided with an annular integral extension 12, which is formed upon the inner wall of the casing 10. A suitable cap 13 is removably mounted upon the lower section 10 of the casing 9 and retains in place a ring "14, which normally engages 'a flexible packing 15. Upon the upper edge of the section 10 of the casing 9, there is formed an integral extension 16, which projects at right angles to said body portion of the casing 10, and integrallysecured to said extension 16 of the casing 10 is an annular extension 17 of less diameter than the'body portion of the section 10. The extension 17 is provided with an integral annular ledge 18. A removable annular locking member 19 is mounted upon the inner face of the extension 17, and is adapted to' engage a flexible packing 20 for the purpose of compressing the same and causing the packing to impinge against the removable casing 21, employed in the construction of the outer wall of the condensing-chamber 7. The casing 21 may be formed of any suitable material, but 100 is preferably constructed of glass or any suitable non-corrodible substance. By means of the locking members 13 and 19 cooperating with the flexible packing and 20 the easing 21 is positively retained in a fixed assembled position with the other parts of the condenser, for the reason that when the locking members are adjusted upon the section 10 of the casing 9 the flexible packings will be caused to impinge against the outer surface of the casing 21. The lower portion of the casing 21 is funnel-shaped and is provided with a suitable conducting-pipe 22 for the purpose of conducting the condensed vapors to any suitable receiver. Casing 10 and casing 21, secured in an assembled position, as shown in Fig. 1, form an air-tight compartment which is adapted to receive cooling liquids introduced by means of the inlet-pipe 23, which is provided with a suitable valve 24. In constructing the apparatus I provide a discharge-receptacle 25, which is provided with an inclined partition 26, which is shown in dotted lines in the drawings. The dischargereceptacle is provided, by means of the inclined partition 26, with a plurality of compartments 27 and 28. The compartment 27 is connected by a pipe 29 with the still 1. A suitable discharge-pipe 30 is secured to the said discharge-receptacle and communicates with the compartment 28. A dischargepipe 31 provides communication between the outer cooling compartment 32, which is formed between the outer casing 9 and the casing 21, and the compartment 28 of the partitioned discharge-receptacle 25. It is obvious that the discharge-pipe is approximately twice the size of pipe 31 and that the pipe 29 is several times larger than pipe 46. The overflow from the compartment 27 will be discharged through a comparatively large pipe 30, as well as the liquids which are discharged from the pipe 31. The section 11 of the outer casing 9 is provided with a shoulder 33, which is adapted to engage a suitable packing mounted upon the integral extension 16 when the section 11 is in an assembled position with the lower section 10. In the draw ings the communicating member 6 is shown integrally secured to the section 11 and top An extension 34: is formed integral with the section 11 of the casing 9 upon its inner face and is adapted to receive a suitable packing 35. Above the packing 35 and within the section 11 is removably secured an annular rigid member 36, which is provided with parallel flanges and a body to which said flanges are integrally secured. Above the annular member 36 is mounted asuitable annular packing 37, and above said packing 37 there is interposed between the removable cap 38 a suitable washer or rigid packing 39, which engages the upper face of the packing 37. When the cap 38 is screwed upon the section 11, its inner upper face will engage the rigid recess member 39; said membcr39 will press upon the packing 37, causing the same to be expanded, and the members 36 will likewise cause the packing 35 to be expanded, thereby engaging the inner cooling-casing 11 when the parts are in an assembled position. The inner cooling-compartment -10 is formed by assembling with the other parts a casing -11, formed of glass or suitable non-corrodiblc material, said casing being provided with a removable cap 42. The casing 41 has a. plurality of integral bulbs 43, which produce a roughened-surface wall. An inlet-pipe 4A is removably mounted upon said cap i2 and is provided with a pipe 45, which projects toward the bottom of the casing 11, and is arranged within said casing for the purpose of introducing the cooling liquids near the bottom of the cooling-casing. The liquids which are supplied to the casing il are adapted to be discharged therefrom through the discharge-pipe 46 and thence into the compartment 27 of the partitioned receiving-receptacle 25.

Referring to Fig. 2, the projection the casing 9, is provided with integral sions 4:7 for the purpose of providing means for carrying a thumb-screw 48. Said thumbscrew is adapted to engage a suitable scrowthreaded aperture formed within integral cxtensions 49, projecting at right angles from the lower section 10 of the outer casing 9.

In operation the cooling liquid is introduced into the outer cooling-compartment 32 by means of the inlet supply-pipe 23, and from the said compartment 32 the cooling liquid is discharged through the pipe 31 into the compartment 28 of the partitioned discharge-rcceptacle 25 and thence into the discharge-pipe 30. It will be apparent that any grade of water may be used in this cooling-casing; but in the construction employed in this apparatus for distilling purposes it will also be ap- 33, of extenparent that water or other liquid may be employed for introduction into the inner cool ing-receptacle 40, and the liquids which are discharged therein are discharged subsequently into the com 'iartment 27 of the partitioned receptacle 2 and thence into th still for the purpose oi aporization, and thence, by means of the member 6, into the condensing-chamber 7, and thence to a suitable reservoir arranged for the reception of the condensed vapors. Owing to the inner cooling-casing being provided with the bulging portions, which increase in diameter toward the lower end thereof, the space within the con(lensing-chamber is decreased toward the lowest end thereof. The vapors when first entering the condcnsing-ohambcr come in contact with the inner wall of the outer cooling-casing and the outer roughened surface of the inner cooling-casing, and as they are forced toward the discharge end of the condensing-casing, they are compelled to pass between the two cooling-surfaces, toward the bottom of the compartment.v The space bethus compelled to come in contact with the lower bulging portion forming the bottom of the inner cooling-casing.

A valve 50 is mounted upon the inlet-pipe H for the purpose of controlling the amount of liquid which is discharged into the inner cooling-receptacle, and, subsequently, into the compartment 27 of the receptacle 25. It will beobvious that by this means the amount of liquids supplied to the still can be easily controlled, and if by any means the supply would be greater than the demand the liquids may overflow and be discharged into the compartment 28 and thence into the waste-pipe 30.

It will be apparent" from the foregoing description that in constructing a completed apparatus certain modifications, alterations, and changes could be resorted to without materially changing the spirit of the invention, and

I therefore reserve the right to make such alterations, modifications, and changes as shall fairly fall within the scope of the invention.
