Specification of Letters Patent.

Application filed January 6, 1911. Serial No. 601,229.

This invention relates to improvements in Vaporizers. V

The object of the invention is to provide means for vaporizing various chemicals in aseries of Vaporizers andintroducing the gases to a mixing chamber common to all the Vaporizers and into which said vapors pass, and from which they are drawn to a patient.

A further object of the invention is to provide means, whereby on or a combination of gases may be .drawn mm the mixing chamber to-treat a patient.

The invention also comprehends improvements in the details of construction and arrangement of parts which will be hereinafter described and particularly pointed out in the claims.

Figure 1 is a plan view. Fig. 2 is a vertical central section on the line A-A, Fig. 1.

Fig. 3 is a horizontal section on the line BB, Fig. 2. Fig. 4 isa side elevation of the apparatus.

The numeral 1 indicates a tank to hold a volume of water, indicated at 2, to be used as medium for vaporizing the chemicals.

' 3 indicates a top provided with a'depending annular flange 4, which fits within the tank 1. and in addition to this flange, the 1 top is formed with several separate depend- .ing annular flanges 5, for supporting an equal number of chambers, 6, 6, 6", 6, 6, 6 5'. The central chamber 6, is what I will ,te'rm'a mixing chamber, while the remaining chambers are vaporizing chambers, into which the various chemicals and gases are introduced.

Fitting in an opening in the top 3, over the vaporizing chambersare valves 7 7, 7", 7,7 and 7 from the lower end of which depend pipes 8,-8, 8 8,- 8, ad 8 extending P lla il :1

down within a short distance of the bottom.

of the chamber. casing and a valve proper, the latter fitting snugly on a seat 8". The valve proper is surrounded by a. chamber 9, formed in the cas-.

Each valve vcomprises a.

ing,'with which pipes 10 communicate, each pipe leading to the adjacent valve casing.

over the vaporizing chambers.

Leading into one of the valve casings are two pipes 12 and 13, the pipe 12, having a valve 15, while pipe 13, is provided. witha. valve 15. To the pipe 12, is connected a tube leading to asource of supply of oxygen (not shown) and to the pipe 13 is c'onnected a tube leading to'a source of'com-' pressed air (not shown).

Located in the p 3 and over thevapon i'zing chambers, are valves 17, 17?, 17*, 17,-

17 and 17 connected by short pipes 18, with a copling- members 19, 19,19 ,19,l9 and 19.9

to which pipes 20 are-attached. Thepi es 20 extend down within the mixin chem erf 6, to within a short distance of t e'bottom thereof, and each of said Lpipes is curved ins,

\vardly at its bottom to cause a thoroughf intermixing of the gases when the apparatus 1s m use.

Extending from-the p and cmninunis eating with the mixing chamber 6', is an outlet pipe 21. Extending from the ipe-21 are two pipes 23 and 23, provide valves 24 and 24. pipes are tubes 27 and 27, to the ends of which may be secured-a spraying orotherdevice for conveniently applying the vapors" for medical use and to the pipe 27, may be attached a bulb 22, as shown in Fig.

with. On the ends of these The valves 7, 727, -7- and 7 have point} ers 30, 30, 30, 30, and 30, which operate over dials 31,- 31, 31", 31, and 31. The:

the flow of gas passing 6, 6, 6, e and (S Handles 32, are secured to the top 3, for

convenience in handling the apparatus.

venient space between 'a false bottom 34,-

and the bottom of the tanlcfor a burner 35.

pointers operating 'over the dials indicate. from the chambers The burner 35 is connected toa pipe-36 having a valve '37 leadin to source of g I supply for the purpose of heating the water: 1 in the tank 1. In order'that the temperature of the water in the tank maybe observed by the operator, a thermometer38, is-located in the side of the tank, as indicated inFig. 4,

and in order that the pressure at the outlet nebulizer 40 which may or may not be used,

depending altogether upon the nature of the oil or chemical placed in' the chamber 6.

gen and a source of supply of 4 In operation, such chemicals as may be desired are introduced .in the vaporizing chambers appropriate to the treatment of a stated case, and ;then the top is-placed on the tank 1, with the lower ends of the vaporizers immersed in the water 2 and the gas is ignited at the burner35, to heat the water, as is the custom in anapparatus of this character. When nebulizing or vaporizing of the chemicals or substances in the various chambers has taken place, the operator may by manipulating the various valves in the pipes leading" from the vaporizing ehanrers to the mixing chamber allow a flow of selected vapor or gas to ass into the mixing chamber. the valves 17, 17., 17", 17, 17 and 17 one. or more, of the various gases or vapors in the chambers may be introduced tofthe mixing chamberaccordingto the treatmenhdesired. If the treatment warrants the use of a certain chemical gas or vapor from any.'particu lar chamber,- the corresponding valves are turned toshut off the supply, so thationly the gas from the chamber selected will pass to the mixing chamber nd thence from the outlet pipe 21 to the distributing pipes 23. and 23. On the other hand, if a mixture of such gases or vapors is desired, the respective valves of the chambers containing the particular gaseswill be 0 ened to be intro.- ducedto the mixing cham of the ends of the depending pipes20 being curved at their lower ends toward each other a thorough mixing of the gases takes place before passing'through the exit ipe 21. To distribute .the gases under pressure throughthe pipes 23,23, the valve 15" in pipe 13 is opened and the valve 15 in pipe 12 is closed, and the air under pressure will pass throughthe respective connecting pipes 10 and into the' chambers forming part of the valves 7, 7, 7", 7, 7, 7. By opening the valves 7, 7 7', 7, 7 and 7 theair will passdown through the pipes S'into the chambers and thereby force the gas or vapor therefrom and into the mixing chamber. The pipes 12 and 13, as previously stated, are connected respectively to a source of supply, of oxy compressed air, said pipes being controlled by the valves 15 and 15. Assuming that the chemical is to be vaporized in cylinder 6, the valve stems-of all the valves 7, 7, 7,7, and 7 will be screwed down to close communication with their respective' chambers. Valves "7 and 1 7', will be opened to afiord communieav Obviously, y manipulating er, and bymeansv the annular chamber surrounding the valve. stem. ThlS space communicates by means of the pipes 10 with similar chambers in the corresponding valve casings of the valves 7, 7, 7", 7, 7, and 7. The compressed air passes through the pipe 8,in chamber 6 and forces the'vapor generated therein upward through valve 17 which has previously been opened, through the pipe 18 and vertical pipe 20 into themixing chamber 6'. From this chamber the vapor under pressure passes through the outlet pipe 21 to the distributing pipes 23; One of these pipes is to be used when a patient is able to endure the full pressure from the compressed air supply frompipe 13. The other distributing pipe 23 is to be used in conncction'witha bulb 22. This bulb receives a charge by suction and the charge is discharged by compression and is intended to be used only when gentle applieation .gf

result is e ected by the hand of the operator rather than by the greater pressure from the tank from which the air is supplied. When administering oxygen, the cut oil valve'15 in pipe '13 is closed and communication may be had with ony one or several of the vaporizing chambers by manipulating the valves. If oxygen alone is to be administered,'all of the outside valves 7, 7, 7

. 7, and 7 will 'be closed. Valves 17 6 will remain open to afford communication with the chamber 6' -The oxygen under pressure is forced through ipe 12 into the valve case 7", down through t e vertical pipe 8 and into the warming chamber 6, thenout through the valves 17* and the pipes 18 and 20- and into the mixing chamber 6', thence through the outletpipe 21 into either of the distributing pipes 23 23 to be used under direct pressure or through the medium of the hand The supply of the'vapor is to be made, which' bulb as above described. When a mixture of oxygen and air is desired, the same is accomplished by a proper manipulation of the valves 15 and 15 in the pipes 12 and 13.-

By arranging the parts as described, a convenient and compact apparatus is provided which may be used for medicinal purposes and by the manipulation of the valves, various mixture of gases, or a particular gas, may be employed in the treatment of a case as the-circumstances may require. lVhat I claim is: 1.
