Patented Feb. 19, 1924.

To all whom it may, concern Be it known that I, ARLINGTON H. MOORE, a citizen of the United States, residing at Dayton, in'the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Fume Generator for Baths, of which the following is a specification.

This invention relates to vapor generators, and more particularly to an ap paratus for charging steam, 'air or gases with chemical vapors or impregnating such carrying medium with chemical or other substances.

The object of the invention is to simplify the structure as well as the means and mode of operation of such Vaporizers or imprege nating apparatuses, whe'reby they will not only be cheapened in construction, but will be more efficient in use, positive in opera tion, automatic in action, easily operated and oontrolled, and unlikely to get out of repair.

A further object of the invention is to provide means for increasing the contact of the carrying medium whether the same, be steam, air, or gases, with the chemical or material with which it is to be charged and for insuring the passage of the carrying medium to the body of charging material.

A further j object of the invention is to provide improved concentrating or condensing means to which such 'a moisture is extracted from the charge medium, leaving the carrying medium more highly charged with the chemical or impregnated to a greater proportional degree. V

A primary object of the invention is to provide a generator, for medicinal vapor baths, wherein steam will be thoroughly saturated or impregnated with the medicinal materials, and thereafter tempered ,or cooled, and the moisture extracted before reaching the patient in the bath cabinet.

With the above primary and other incidental objects in view as will more fully appear in the specification, the invention consists of the features of construction, the parts and combinations thereof, and the mode of operation, or their, equivalents as hereinafter described and set forth in the claims. v v r .Referring to the drawings Fig. 1 is a side elevation of the assembled ap aratus, the

Fig. 5 is a bottom plan view of the dome or a top cap of the agitator. Like parts are indicated by similar characters of reference throughout the several views. I

In certain therapeutic treatments vapor baths are employed consisting of steam or.

in some instances, hot air, which has been highly charged with medicin'alfchemicals,

drugs, or compounds. Inthe preparation of the mineral vapor or medicinal vapor baths, various materials are employed either independently or in combination, such as creosote, sulphur, salt, variousoils, certain acids, and like materials. Heretofore, it has been the practiceto conduct the carrying medium, that is, the air or steam,

through a tortuous passage over pans or traps containing such materials." However,

the mere surface contact of the carrying medium, with the impregnating materlal,

does not take up the material in suflicient quantity or with sufficient 'rapidity. In order that the carrying medium I may be more quickly charged to greater. degree of impregnation, the present apparatus hasbeen designed. i I v In the drawing, 1 is the generating chamber, adapted to contain a quantity of the chemical or medicinal materials intermixed with a quantity water or otherfluid to i be employed in the treatment. The chenncal or medicinal'material may be held in solution within the generating. chamber, or it may be of a character insolvent in wateror the otherfluid which may be employed,

with which it is merely intermixed and cither held in state of suspension, therein, or in the form of a precipitate. Many'of the materials employed for this purpose will be found to be insoluble and are maintained in a state of intermixture with the water or other fluid'by constant agitation,

Beneath the generator 1 is shown 'a heating apparatus 2 in the present instance a gas burner, by which the contents of the gem erating chamber are subjected toboiling temperature. Located in the bottom of the generating chamber 1, and submerged in the contents thereof, is a dome shaped or conical compartment 3, having" access opga ings 3' adjacent to the base thereof, which" ,eon'tents of theagitating chamber 3 being communicate with a chamber of the gcnerator l. The fluid contents of the gen: erator are thus free to circulate thru the compartment 3. Risin from the apex of the conical or domed compartment 3 is an upright tube 4, open at its upper end, but overhung by a dome or cap 5. The dome or cap 5 is supported upon radial arms 9 carried by a collar 7, surrounding the upper end: ofthe upright-tube 4:. Supported upon the upright tube 4, beneath the cap or dome 5, and in spaced relation one with. the other is aseries of; transverse perforated: diaphragmsor diffusing plates 6. These dia: phragms or diffusingpl atesb are of a diameter. substantially equalto the internal diameter-of the generator 1, and are contrally perforated to fit upon the upright tube- 4; They are separated one from the other by intervening; spacer sleeves 18. The lowermostdiaphragm or diffusing plate of theqs'eries restslupon a collar 8, secured upon the tube 4;. There may be any number of these; diffusing'platesaccording to the character of the: material, and the degree of diffusion or intermixture required. Inthe drawing', there has been shown but two diaphragms; or diffusing plates. 6. These diaphragms ordifiusing plates may comprise woven Wire screens or thin sheets of metal or other ma-ter-ials, having therein a plurality: of smallpe-rfomtions. The material employedfor these plates will depend somewhatupon: the character of the chemicals or medicinal materials with which the vapors are tobe charged. It will be at once apparent thati'certain metals might have a catalytic effect upon these medicinal materials, or the metalmight be attacked by the chemicals or medicinal materials, with which the metallic vapors might combine toform injurious or undesirable combinations. Hence for use in relation with materials of certain characters, these diffusing diaphragms may be of glass, porcelain, composition, or phenolic condensation mate rials. The perforations of the various diaphragms or diffusing plates are preferably though not necessarily of diflerent sizes, whereby the diffusion or breaking up of the vapors and intermixture of the chemical or medicinal vapors and the steam is more uniformly and progressively effected.

The contents of the generator 1 being subjected to heat fromv the burner 2 are caused to boil thereby generating steam within the generator chamber 1, from the chemical charged water or other liquids. MThile the entire contents of the generator are caused to boil and generate steam, the

more directly subjected to the heat of the burner '2, are caused to'boil more violently,

than that portion of the contents out. do

,said agitating chamber.

m l This causes the contents of the chamber Z; to risethru the vertical tube a, and discharge over the top thereof, thus inducing a continuous current or circulationwithin the generating cham her. As the highly heated and agitated contents ofthe chamber 3 are discharged upwardly thruthe tube 4, the chamber 3 is constantly suppliedwith fluid thru the intercommunicating openings 3. The highly heated and agitated liquid discharged upward thru the tube at carries with it a considerable quantity of the chemicals or medicinal materials, which overflowing the top of the tube 4 are deposited upon the diaphragms. or diffusing plates 6, (liitiniilg backward therefrom thru the perforations of the plates into the lower portion of the generatingchamber 1. During this process, the agitated liquid is broken up into very small portions or fine streams, or in some instances in drops or globules, which drip from the diaphragms 'or diffusing plates 6. The descending charged liquid draining from. the diaphragms. or diffusing plates 6,

meet or. intermingle with the steam and vapors arising from the main body of the liquid in the generating chamber. This steam and vapor generated by theboiling of the main body ofcheinically or medicinally charged water or other liquid is, of course, charged to some extent vith such chemicals or medicinal materials. However, in the passage of this body of vapors or steam thru the perforations of the: dia-- phragms or diffusing plates .6, meeting and mingling in such passage with the subdivided. body of Charged liquid, becomes further impregnated. or, charged to, a, much higher degreewith such chemicals ormedicinal materials. It will. be noted that the rising vapors or steam from the-main body of the liquid and :the highly charged and heated liquid draining from the diaphra-g ns or diffusing plates, meet and pass in opposite directionwithin. the generator. Moreover there will always be more or less of the. liguid adhering ,to the. diaphragms land diffusing platesv thru which the steam and vapors. must pass. 1 The constant discharge of the heated liquid, highly charged with chemicals or medicinal materials, over the diaphragms. or diffusing plates 6 leaves upon such plates or diaphragms a more or less concentrated solution or deposit of such chemicals, and medicinal materials, with which the rising vapors and steaijn are brought into direct contact. By this means the steam and vapor is caused to become highly saturated with the chemical or medicinal material ,beforepassing from the generator chamber.

' 'Theficharged steam and vapors having passed upwardly thru the descending drippings or draining of highly concentrated solution or charged liquid, and thence thru dry remaining steam 'agreater proportional charge of the medicinal or chemical ma terial. The condenser or intensifier 11 comprises a central chamber 12 divided into two compartments by a medial wall 13 extending in proximity to, but somewhat veniently withstood by the patient. 'With-* spaced from the bottom of the compartment 12 to afford intercommunication between;

the respective "compartments beneath the" wall or bafile '13. Surrounding the chamber 12 is a water jacket 14,Ithru which cold water is circulated for condensing purposes. The cold water supply enters the jacket at 15, and aftercirculatin'g about the exterior of "the chamber 12, is discharged thru the outlet 16. In the bottom of "the compartment 12 is a drain 17 for the water'ofcondensation. The charged steam entering the chamber 12 thru the conduit lO is usually heated to a greater degree than can be conin'the chamber l2- this charged'steam, is somewhat cooled and the excessive vmoisture is deposited,,the highly charged residue of steam passing beneath the medial :wall 13 into the opposite compartment of thechamber '12, thence leaving thecondenser or intensifier 11, thru the discharge conduit 20, which leads'to'the bath cabinet not shown in the present drawing. This insures the medium being uniformly andthoroughlysaturated with the medicinal or chemical material. i I I g Thepu'rp'ose of the cap or dome 5 of the generator l is to intercept the charged liquid ejected front the vertical tube' l, and direct it downward upon the diaph'ragms or diffusing plates 6. The dome or cap '5 prevents enlarged globules 'of'liquid from being. entrained with the 'steami 'and vapor and carried from the generator thru the outlet conduit 10. The dome or capf5v is preferablytliough notfnece'ssarily of greater diameter than thexoutlet conduit 10 and positioned concentrically therewith. v I There is shown at one side of the "generator 1', a filling tube 19, thru which the contents of the ished.

generator may be replen- Fronrthe above description, it will be apparent that there is thus provided device of the character described possessing. the particular features of advantage beo1-e enumerated as desirable, but which" obviously is-susceptible wof mo dification in its form, proportions, detail construction and arrangement of parts without departing fronrthe principle involved or sacrificing any'of its advantages.

While in order to comply with the statute the invention has" been described in language more or less specific as to structural features, it is to 'be understood that the invention is not limited to the specific details shown, but that the means and construction herein disclosed comprise but one of several modes of putting the invention into effect, and the invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the appended claims. 1?
