Specification of Letters Patent. A

Patented Sept. 11, 1906.

Application filed February 23,1905. Serial No. 246.960.

T0 @ZZ whom it may concern,.-

Be it known that I, JAMES E. VAN Nuss, a

States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Vaporizers, of which the following is a specification. A i

This invention relates to vaporizing and nebulizing devices of that class which are used in the administration of medicine in the medicated vapor or nebule to diseased organs, more especially those of the nose, throat, and lungs; and the invention has for its leading object to provide an improved device of this class whereby a much lstronger gas or vapor can be generated than has heretofore been possible and whereby also the essential oils of the medicine employed can be taken up and carried over in such strength and highly-divided form as to be of practical value and efficiency through local application in contradistinction to many vaporizers and inhalers now in use which deor Weak vapor impregnated with littlemore than the odors of the medicinal agents used therein.

The device of this invention, in common .with many similar devices now in use, em-

ploys an outer vessel containing a pungent solution, such as ammonia, and an inner vessel containing an acid solution,'such as hydrochloric acid, with means for forcing a current of air into said inner vessel, then conducting the acid fumes therefrom over into the outer vessel in contact with the ammonia solution therein, and thence conducting the resultant ammonium-chlorid gas through a suitable discharge tube or nozzle to the affected organs.

of the patient; but the present invention is distinguished from prior devicesv of this class in several important respects, as follows:

employment of a special cony the air and vapor conducting tubes of the device, whereby the air introduced to the acid solution is caused to carry over more acid fumes and of greater strength struction of Y than have heretofore been possible of attainment, thus permitting the useof a stronger ammonia solution, and whereby the acid fumes are caused to act similarly upon the ammonia solution in the generation of a --strong ammonium-chlorid gas or vapor; second, in the employment of a flexible dischargetube having a medicated sponge located in an interchangeable delivery-nozzle directly in thepath of the pure gas or vapor emitted by the device, whereby said gas or vapor takes up and carries over the essential oils containing the principle of the medicine einployed without requiring the globule or globules to travel through said discharge-tube, to which it is likely to adhere; third, in the employment of a glass or ar surrounding the gas-generating devices and ontaining a water-bath in which the gas or vapor generated in the vaporizer is thoroughly washed and relieved of any impurities or excess of either agent prior to its discharge and subsequent medication, this feature being especially designed for the apparatus as used by physicians, in which case, the entire apparatus may be conveniently packed fourth, in the employment of vapor-conducting tubes and other parts of hard rubber as distinguished from the glass tubes heretofore used in such devices.

The invention also includes as an important feature contributing to its simplicity of construction a cored closure or stopper which affords a passage for the acidified gas directly to the tube leading to the ammonia solution and also a passage for the gas generated from the interior of the containing vessel to the discharge-tube. Y

My invention in its preferred form is illus- -trated in the accompanyingdrawings, where- 1n- Figure l is a vertical sectional view with the air-inlet and gas-discharge tubes shown partly in elevation, and lFig. 2 is a bottom plan view of the acid-gas-condueting tube of the device. i

Referring to the drawings, 5 designates an outer vessel, preferably in the form of a glass jar, having an externally-threaded top portion 5a, to which is adapted to be screwed a cap 6, preferably of hard rubber, The upper end of the ar 5 is occupied by a stopperplate 7, consisting, preferably, of a hardrubber circular disk of considerable thickness which is provided at its upper end with a horizontally-extending flange 7, resting upon the upper end of the jar through an interposed packing ring or gasket 8 and a depending eXternally-threaded flange 7". The cap 6 has an internal annular shoulder 6L formed thereon, which when the cap is screwed onto the jar securely clamps the in a portable case;v

TOO

stopper 7 to its seat on the upper end of said ar. l Secured to the depending flange 7b is an inner vessel 9, into which extends a pair of

tubes

10 and 11, both of which are screwed at their upper ends into internally-threaded recesses or

sockets

12 and 13 in the lower face of the stopper-plate 7. The upper Vends of

tubes

10 and 11 are in free communication with each other by means of a horizontal duct 14, formed in and through the stopperplate 7 between the

recesses

12 and 13. Secured in the stopper-plate 7 and extending` from the upper face thereof a considerable distance into the tube 1() is a smaller tube 15, which is provided with a minute axial bore 15, substantially capillary in size. The lower end of tube 10 is closed, while the lower end of tube 1 1 is provided with one or a series of minute a ertures or perforations 11, Fig. 2; Securet in the bottom of the vessel 9, preferably centrally thereof, is an upstandmg gas-discharge tube 16, open at both ends and extending to something less than the full height of the vessel 9. Secured to the upper face of the stopper-plate 7, centrally thereof, is a short tube 17, having a reduced externally-threaded upper portion 17 passed through the cap 6 by an air-tight joint, to which is attached, by means of a nipple 13, a flexible discharge tube or hose 19. Cored in the stopper-plate 7 is a rectangular duct 20, the short vertical portion of which registers with the bore of the tube 17 at its lower end, while the horizontal portion leads to and through the annular marginal surface of the.

stopper-plate, communicatingfreely at that point with the interior of the outer jar 5. To the remote end of the hose 19 may be connected through a suitable axially-bored connection piece or stem 21 a nipple 22, hav- 1 ing its bore somewhat enlarged to provide a chamber 22a, adapted to contain a medicated sponge 23.

Tapping the cap 6 is a nipple 24, to which is attached a hose 25, through which compressed air may be supplied from a hand bulb, pump, or any other suitable or convenient source of compressed air.

The outer vessel 5 is designed to be partially filled with water. The tube 10 is filled to a level slightly below the lower end of the .inner tube 15 with a suitable acid, such as hydrochloric acid, and the vessel 9 is filled., preferably to a level slightly above the lower end of the tube 11, with a neutralizing agent, such as strong ammonia-water. The-sponge 23 is loaded with the essential oil of any suitable medicinal drug, so as to impart to the gas forced therethrough an agreeable aroma or medicinal quality, or both, as may :be desired.

In the operation of the device compressed air introduced through the tube 25 and nipple 24 fills the chamber between the cap 6 and stopper 7, from which such compressed air flows in an attenuated stream, but with considerable speed and force, through the capillary bore of the tube 15, issuing from the lower end of the latter in a line jet, which impinges upon and penetrates the upper portion of the acid. contained in tube 10, producing 'a bubbling and boiling of such acid and generating acid fumes or gas in greater volume and of `greater strength than where the air-current merely passes over the surface of the acid. These rise through the tube and flowing through the communicating duct 14 enter and 'lill the tube 11 and by their pressure expel the amn'ionia-water in the latter tube through tits lower end and issuing in fine jets or sprays through the series of apertures 11a thoroughly mix with the ammoniawater, rising therefrom into the upper part of the vessel 9 in the form of a strong ammoniumchlorid gas, which gas flowing downwardly through the tube 16, is thoroughly washed and cleansed of all impurities in the water surrounding the lower end of the vessel 9, be-

ing relievedv therein also of an excess of either- IOO tube 15 is so fine as to produce a strong airjet of an almost needle-like character well adapted. to pierce the underlying body of acid liquid and efl'ect the generation of acid fumes of great strength. Similarly the finelydivided and jet-like condition in which the said fumes are sprayed into the ammoniawater effects a perfect combustion and neutralization of the acid by the ammonia, for which purpose a very strong solution of ammonia, on account of the strength of the acid fumes, must be used. The increased strength of chemicals employed thus gives an increased strength of resultant ammonium chlorid. The location of the entire Vaporizing apparatus within the inclosing vessel or jar containing a washing and cleansing liquid makes a simple and compact device wherein the cleansing fluid is capable of being renewed by simply unscrewing the cap 6 and lifting out the stopper-plate and its attached parts. In some cases it is desirable to administer the gas in a warm state, and this may easily be effected in the present apparatus by supplying hot water as the gas-cleansing liquid. The provision of a considerable tube opening through its base, of a closure space between the cap 6 and the stopperplate 7 affords an air-reservoir at such point, which is of considera )le importance as contributing to the uniformity and steadiness of i the flow of compressed airl into and of gas from the device.

The several vapor-conducting tubes of the apparatus and, in fact, all the parts thereof except the outer jar 5 and the inlet and

discharge tubes

25 and 19 are by preference made of hard rubber, the benefits and advantages of this material residing in the elimination of the expense and waste incurred where such parts are made of glass, as is the common practice at present, and in the facility of coring the several parts, the sizes of the ports and passage-ways therein being capable of greater accuracy and uniformity in their manufacture in a molded material like rubber than in a drawn material such as glass.
