To all whom t may concern:

4Be it known that I, rELDnR, a citizen of the UnitedStates, residing at Chicago, in the county -of Cook and State of Illinois, have yinvented certain new and useful Improvements in" Removing Al-` l cohol from Liquors, of which the following isa specification.

` My invention relates toa process-and apparatus for removing alcohol from liquors and has for its primary obJect the provision whereby the liquor, after having the alcohol removed, 'shall remainl free frommthe well known burnt taste commonly found in de steam or other equal heat media are eme ployed.

Other objects and advantages of the invention will appear from the following description taken in conjunction with the accompanying drawings which form a part of this specification.

In the drawings Figure 1 is a section taken substantially on line 1-1 of Fig. 3; Y

Fig. 2 is a section taken substantially on line 2 2 of Fig. 1; and

Fig. 3 is a section taken on line 3-3 of Fig. 1.

Reference numeral 10 indicates the body portion of a large tank preferably rectangular in cross-section, provided with a cone shaped cover 11 secured to the tank by a fluid tight joint and communicating at its top with the pump, generally indicated at 12, for withdrawing vaporized alcohol from the tank.

Secured within the tank are a plurality of superposed downwardly slanting brackets 13 each of which supports a coil of hot water pipes 14, alternate brackets being oppositely slanted, and all of the brackets terminating short of the opposite wall from that to which they are fastened.

As best illustrated in Fig. 2, the apparatus is provided preferably with two circulating coils. I-Iot water enters the coils from a hot water main 15 and is discharged through a heat exhaust pipe 16. The main 15 carries a branch 17 which feeds hot water' `Speciti-cation of Letters Patent.l i Patjmtdl Dljl, 1917 Applcton filed May`29, 1917- Selal Nl). 171,750.

. vto the upper coil-1S andra lower branch 19 ROBERT H. Prune-v whichfeedshotlwater to the lower coil 21.

Theexhaust pipe 16 has an upper branch 22 y liquor from oneto another in a zigzag course downwardly through the tank, as best seen inFig.11,each of these pans being upturned of an `improved vprocess and apparatus` 1 at its higher endas at 25 and down turned at its' lower end as at 26, the slant of the pans being such as to cause liquor delivered to the uppermost pan through a delivery pipey 27 to trickle slowly over the pans 24;. From the lower pan 211 the de-alcoholized liquor drops to the bottom of the tank, where it collects in a body, indicated at 28, and is drawn 0H at suitable intervals through a discharge pipe 29, by means of any suitable pump 31. The delivery pipe 27 is as long as the breadth of the pans 24: and is apertured at spaced intervals as at 32 to provide for delivery liquor across the whole width of the pan. Prefer-ably the pans have an area somewhat less than the cross-sectional area of the tank 10, in order to provide room on three sides between the edge of the pan and the wall of the tank for the operator to pass about the apparatus in cleaning it. Entrance into the tank is had through any suitable manhole provided with a door 34C clamped into position in any suitable manner, as, for instance, by means of the yoke 35 and bolt 36.

In the operation of my invention hot water, preferably at a temperature o-f 135 degrees Fahrenheit or thereabouts, is passed through the pipes 141 of the coils 18 and 21 and caused to flow continually therethrough. Beer, or any other alcoholic liquor, is now fed onto the upper pan 24: through the apertures 32 of feed pipe 27. The liquor flows down the heated pans in section and finally drops from the lowest one to the bottom of the tank, whence it may be drawn off by the pump 31. The low inclination of the pans 24 causes the liquor to travel slowly over the heated pans and a sufficient number of pans are provided to make the path of travel of the liquor sufficiently long to vaporize all the alcohol. The vaporized alcohol is drawn off from the top of the cover 11 by means of the pump 12. By employing wateratsubstantially 135 degrees temperature I accomplish the removal of the alcohol from the liquor while leaving the resulting liquor' free from any taste of steam, and the low temperature at which the alcohol .n ,amountnof fuel Aeeded inasmuch asno steam pressureisrequired.

While I have illustratedand described the preferred embodiment of my invention,

f' gitwill be obviousthat one skilled in the art kmay make-modificationsthereof without dei parting from the vspirit of the invention. `I

wish, therefore,l not to be restricted to the .precise embodiment'shown except in so far as the saine islimited in the appended claims. v ,Y 1,1'I`her tank 10. is air tight and the interior Copies of this patient may he obtained lfor ye cents each, by i washington, n. c."

pressure iskept below. atmospheric pressure by pump v12. vIn this way the alcohol is evaporated from thebeer at a temperature' kless than that required under full atmosis removed greatly reduces Vthe pheric pressure so that conservation of fuel iand rapid operation result.

opposite to that from which it is supported,

heating` pipes traversing said brackets, and pans disposed upon said pipes, said pans being adapted to carry a stream of liquor and deliver the same from one pan to the next, the pans being of ysomewhat less area than the cross-sectional area of the tank.

VIn testimony whereof I have aiixed my signature.
