HENRI LAMOTTE, OF PEROY STREET, BEDFORD SQUARE, OOUNTY OF MIDDLESEX, ENGLAND.

IMPROVED APPARATUS FOR RECTIFYING ALCOHOL.

Spccilication forming part of Letters Patent No. 59,1419, dated October 23, 1866.

To all whom it may concern:

Bc it known that I, HENRI LAMOTTE, of Percy Street, Bedford Square, in the county of Middlesex, England, have invented a new or Improved Method of and Apparatus for Rectifying Alcohols 5 and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing, and to the letters ofv reference marked thereon.

The object of this invention is to cause good and tine-tasted alcohols to flow or run oft' continuously, because only alcohols of a high character are allowed to enter the rectifying-column, the foreign matters which had been amalgamated with thc alcohol having been previously condensed in a vpurifier bymeans of cold water.

By means of this new and improved method no taste of copper is given to the alcohol, for, this taste bein produced by the cooling` of the apparatus, and this being always in action, it follows that the cooling cannot take place, and consequently that a copper taste is no longer produced.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

My said invention consists in two distilling or boiling vessels, in combination with a rectifying-column and puri tying-vessels, arranged and operating in such a manner that the rectifying operation can be carried on continuously, and the ethereal products separated from the alcohol at the commencement of charges introduced alternately in the boilingvessels, and the foreign substances separated from the alcohol at the end of the operation.

The boilers are coupled together or united by' products of those alcohols at the end of the heating.

F is a tubular purifier, which only allows the bestalcohols to pass into the column. G is the tubular purih'er, wherein the alcohol conveyed by the lightest fluids at the commencement of the heating is condensed, and for condensing the other foreign bodies conveyed by the alcohol at the end of the heating.

H is a pipe through which the rst products from the boiler' pass to the purifierG. I

:is the pipe leading to the column. J is a pipe the boiler is charged, and the valves Q and S are kept closed. As soon as 740 centigrade of heat are produced, the foreign matters, which are lighter than the alcohol, begin to disengage themselves. The tap M of the purifier G is then immediately opened and a slight stream of water passes through, in order to condense the alcohol which the foreign matters bring with them. As soon as the foreign matters become disengaged, the taps Q and S are opened and the taps R and M are closed.

While the boiler No. 1 is at work, boiler No. 2 may be prepared for work, the action of which is similar "to the other, and it is thus ready for use as soon as the other is iinished. lf, however, the boiler No. 2 is ready somewhat before the other h as finished opera tions, the tap Q of the boiler No.2 may be slightly opened while waiting for the termination of the other. There is no possible inconvenience attending the working, for the alcohol of boiler No. 2 cannot enter that of No.1, seeing that that which commences has only 800 to 870 centigrade of heat, while that which iinishes has from 920 to 950 centigrade. Be-

sides, when No. l is finished the taps Q and S are closed, and the tap R opened and the tap M of the purier, and the rest of the alcohol from the boiler No.1 passes through the preparation-pipe I and tnrough the purifier G, Where all matters foreign to the alcohol bceoine condensed and return in spray into the boiler.

` The action of the boiler No. l being terminated, the tap M of the puritier G only is closed, and the same boiler is charged and discharged as before described.

The purifiers F and Gr arc each formed with a series of vertical pipes, open at their ends, passing through a Water-space formed between heads that receive said pipes through them. The temperature of these purifiers is regulated by Water admitted through the cocks O or M, and runnin g off by an overflow.

The testing apparatus L is made with a small pipe in the inside, acting as a condenser, to furnish liquid with convenience to test when the operation is complete in either boiler No. l or No. 2.

rlhus the one vessel works to produce the good-tasted alcohol when the valves Q and S are open and the valve R closed. rlhe reverse takes place for the other: it has its tap R open and the valves Q and S closed. The tap M Will be open if the purifier G Works.

By the foregoing arrangements the alcohols are very superior, much more work is accomplished, and fuel is economized. The produce is also greater, as it is not necessary to distill a second time all the alcohols which have a copper taste, and which are'dangerous by the combinations of the oxides of copper which form dnrin g cooling.

Another advantage resultiu g from this system is, that more Work is accomplished with it than with two apparatus of the ordinary construction.

What I claiin, and desire to secure by Letters Patent, is-

The boilers A No. l and A No. 2 and rectifying-column or analyzer B, in combination with the purifiers F and Gr, the parts being connected by pipes and regulated by cocks or taps, in the manner and for the purposes set forth.

In witness whereof I, thesaid HENRI LA MOTTE, have hereunto set my hand and seal this 21st day of May, 1866.
