BERRYMAN, OF JULIET, ILLINOIS;` GEORGE WALTERS ADMINISATOB g F SAID MARSDEN L. BERRYMAN, DECEASED BUBBLE QA? FOR OIL DISTILLING APPARATUS u Application led November 13, 1929, Serial No. 466,911. Renewed May 19, 1932.

'(lhe present invention relates to improvements in bubbler caps Vfor oil distilling apparatus, or any hydrocarbon compound, and has for an object to provide a twin cap which fg will perform a double duty and aid in the Amore eilicient distilling ot the oils, or any hydrocarbon compound.

Another object of the invention is to provide a twin cap device in which the usual 3a form of cap may extend in the upper chamber above the tube, while the improved cap will lie in the chamber below and be held in conjunction with the lower end of such tube, whereby caps will be provided for both ends ne of the tube and in both chambers..

With the foregoing and other 'objects in view, the invention will be more fully described hereinatter, and will be more particularly pointed out in the claims appended 8O hereto. c V

1n the drawings, wherein like symbols reer to like or -corresponding parts throughout the several views,

Figure 1 is a side elevation of a tower with parts broken away showing the improved device,

Figure 2 is a cross section taken on the line 2-2 in Figure 1, and i Figure 3 is an enlarged vertical section taken through one of the improved devices.

Referring more particularly to the drawings, designates the tower containing the trays or partitions 11, which separate the tower into chambers 12.

The tube is indicated at 13, and is usually four inches in diameter and approximately nine inches long. Thisftube'13 has-its open upper end dis osed in the chamber 12 above, and its open oWer end of the chamber beneath suchv tray 11. r

1n the form of device heretofore used, an upper cap 14 was provided, being held spaced above the upper open end of the tube 13 as by the shoulders or brackets 15.` This old form of cap 14 is provided with a depending ange 16 of greater diameter than the tube 13 and which extends down and overlaps the upper part of the tube, the lower free edge of the flange 16 being serrated pr scalloped,

as indicated at 17.

ln accordance with the present invention, l provide a lower cap 18 inverted with respect to the upper cap 14, and ll press this lower-cap 18 directly against the lower end of the tube 13 in the chamber 12 below the tray 11. The cap 18 is provided with an upstanding circular ange 19, which is of con- Ksiderably greater diameter than the diameter of the tube 13, and forms an annular channel about the-.lower end of the tube 13 and Within the flange 19. The lange 19 opens upwardly into the interior space of the lower chamber 12. The upper free edge of the ange 19 is preferably smooth or unprovided with serrations. The serrations are provided upon the lower end of the tube 13, as shown at 20, these serrations providing a means of communication between theinterior of the tube 13, and the annular channel conned' within the ange 19,and exterior of the lower (3@ p part or the tube 13.

. '.lhe lowercap `18 is held in placelbythe bolt 21 having the head 22 ,which lies above the cap 14, and provided with thenut 23 below the lower cap 18,"the bolt passing through both caps 14 and 18. Of course, the head 22 might be disposed down below (za-p18 and/ the nut 23 above cap 14, if desired. The bolt holds both caps in place in a tightA and secure manner. @o

ln operation, the vapors carrying mpre or less of the entrained liquid from the tray in the lower 'chamberascending strike the tray 11 and enter the mouth of the annular chamber within the flange 19 ofthe lower cap 13. As the vapors enter the annular chamberL formed by cap 1'8, the entrained liquid is deposited in said chamber.

From such annular chamber, the vapors pass through the slots or serrations 20 and enter the lower part of the tube 13, ascending in such tube until the same strike the up per cap 14. This upper cap tends to kseparate or deflectthe vapors and to guide them downwardly through the annular chamber within the flange 16, and the vapors pass out 'downwardly through the serrated edge 17 and'into the upperfra'ctionating chamber.

In this way, a double duty isperformed by the improved tubes 13 which carry twincaps,l 163 lnely, one cap above and 'a companion cap Fi res 1 and 3 illustrate how the liquid stan in the trays in and around the caps. In Figure 1 is shown a leg 24 or channel for the liquid to flow back or reflux, as indicated by the arrows. The vapors travel upwardly as also indicated by the arrows.

According ,to my method a double distillation takes place because the oil and vapors pass through a double set'o caps. Also as the condensed liquid overflows from the lower caps, it is sprayed into the lower chamber and exposes more surface for evaporation. There is a double liquid seal of the vapors. This method is especially good for vacuum distillation, where the vapors are drawn and not forced through. This double distillation will produce better fractionation with less trays.

It be obvious that many changes in the construction, combination and arran ment of arts could be made, which could used'wit out de arting from the spirit of my invention, and do not mean. to limit the invention to such details, except as particularly ointed out in the claims.

` ving thu'sdescribed my invention, what I claim and desire to secure by Letters Patent of the United States is t- 1. An im roved bubbler cap device comprisin a. tu a-nupper anged cap held in space relation above the upper end Aof the tube, a secondcap invertedwith respect to the upper cap and ed against the lower serrated portion o the tube, an upstanding flan on the last mentioned cap, and means palng through both ofA said caps for suspending the lower cap from the u per cap.

' 2. An im roved bubbler cap evicecomprisin a tu an upper flange cap held in space relation above the upper end of the tube, a second cap inverted with respect to the upper cap and pressed against the lower serratedportion o the tube, and an upstanding flange on the last mentioned cap.
