Speciiicatign forming part of Letters Patent No. l 73,494, dated February 15, 1876; application filed April 14, 1875.
To all lwhom it may concern:
Be it known that I, HIRAM PURDY, of Burlington, county of Des Moines and State of Iowa, have'invented a new and useful Improvement in the Art of' Odorating a Pure `Spirit and other substances 5 7 and I do hereby declare that the following is a full, clear, and
exact description thereof', reference being had to the accompanying drawings making a part of' this specification, inwhich- Figure 1 is a plan view of' the apparatus employed by me for odoratin g liquids or other substances; and Fig. 24 a vertical cross-section in the line :v m of Fig. l. The covers of the apparatus shown by Fig. lare removed in this view;v
The object of my invention is to odorate pure spirits, or other substances not liquid, by passing air, at a suitable temperature, and having a proper degree of moisture, first through any desired odoratin g substance, and
. thereafter through the substance to be odorated, as will be hereinafter described.
In the drawings', A represents a tub of' proper dimensions, having a close-fitting cover, and is provided with a coil of pipe, f, the outer end laof whichcoil extends'iintothe tub near its bottom, from which point the coil rises to nearly the top of the tub as at a', at
which point it passes through the tub A and enters an adjacent tub, B, at the same height, and thence passes down to the bottom of the tubB and around the interior thereof in the form of a coil, f1. An adjacent tub, C, is provided. with a pipe having a coil, f3, around its interior, as shown, and which, rising to the height of the tub, passes th'roughthe cover 7c, and so bent, as atfz, that the outer end of such bent portion may pass through a` close tting perforation in the cover of the tub B, and thus communicate therewith. -A like pipe, as shown at f4 and f5, is provided for the tub D, and in like manner is made to communicate with the tub C. And in a similar manner a coil of pipe, as at f6 andf7, in thel interior of the tub E, is made to communicate with the tub l), which coil has its lower outer end, as at g, extend through the lower The lower ends a2 of the several coils are closed, but apertures, as at b, are made in the coils on .tents of' such tub.
the bottom of the tubs B, G, and D, for the escape of' heated air into and through thecon- In the operation of' the apparatus, I ll the tub A with water, heated toa temperature sufficient Vto heat air, which by any proper means may be forced through the coil f at its outer end a. lThis coil should be of' sufficient length within the tub A to readily and effectually transmit the heat of' the water'to the air passing through the coil. B is thetu'b for saturatin g the heated air with moisture, after pipe f1 will be compelled to pass through the water, andthus absorb or become saturated with' moisture. The odorating substance is placed in the tub O, the tub being more or less filled therewith, according Ato the degree of' strength of odor which it is desirable to impart to the substance to be odorated. The air having become saturated by being forced through the water'in tub B, escapes therefrom through the pipe f2 f3 into the bottom of' the tub O through the perforations b,'and so mingles with and passes through the odorating-substance placed in said tub, and thence escapes through the pipe f4 f5 and perforations b into the tub D, which tub is filled more or less with the liquid or substance to be odorated. The heated and moistened air heilig forced through the odorating subst-ance in tub C, readily becomes charged with the odor of' the odorating vsubstance placed therein, and in passing through the pure spirits or other substance placed in tub D, imparts thereto the odor with which it has becomecharged in itsA passage through tub C. After the air has passed up through the pure spirits or other substance contained in the tub D, it finally passes off through a condensing-coil of pipe f6 f7, which is made to communicate with then forced through the series of tubs and coils to the outlet-coil in tub E.
What I claim is- 1. The process described for odorating liquors and other substances, consist-ing` in saturating heated air with aqueous vapor, and passing` such air through an. odorating subY stance and into or through a liquid, or other substance to be odorated, substantially as described.
2. I claim the combination of a heater, a
Water-bath, an odoratng tank, and a containing tank for holding the substance to be odorated, and connecting-pipes, substantially as and for the purpose described.
