    Ltike’s Improvements in Apparatus for the Inhalation of Medicinal Vapowi s. said air filter tube K1 and filter K are placed at another point of the circum¬ ference of the air-space of the boiler, for the purpose of causing the air entering the filter K to circulate within the air-gap l* before escaping into the said tube L. The aforesaid tube L connects the air-gap b4 with the chamber B2 in which a steam tube M1 is arranged parallel^ to the tube L. The said steam tube M1 is 5 connected to a tube If'5 of the boiler and is provided with a coch iM intended to pu^ the right-hand portion of the apparatus in or out of action; b+ is a blow-off cock. On the casing J32, which is provided with a receptacle S for condensed steam is provided a vertical tube 0 m the bottom of which a perforated box N is arranged for the purpose of containing a suitable medicine through which the steam 10 will be obliged to pass before escaping through the tube 0 and the flexible pipe Q, into the mouth of the patient. The vertical tube 0 contains a series of superposed conical partitions <fi, o2, o3} o4 provided with suitable holes for causing the steam passing the said tube 0, to take an irregular course in the manner shown by the arrow in the drawing and to be thereby cooled. . 15 The conical partitions ol, o2, o3, o4, are connected with one another and with the top-piece P by means of a rod O1, so that when the top-piece P is withdrawn the said partitions o\ o2: o3, o\ are also withdrawn to allow the tube 0 to be easily cleaned. The top-piece P is a valve-box in which a return-valve y1 and a blow through 20 valve y2 are arranged. The return valve y1 is formed of a star-shaped plate which is free to move up and down and is guided by its points. The blow through valve y2 is formed of a disc which is also free to move up and d,own. Over the said valve y2 there are provided several openings y3. The cover P2 of the top-piece P is likewise removable. . 25 The nozzle P1 of the top piece is provided with a flexible pipe Q to which a mouth-piece P (Figure 1) or P1 (Figures 2 and 3) is affixed. If steam is produced in the boiler and if the cock in the steam tube is open, the. steam entering the casing B2 through the tube M1 causes a suction to be produced in the connecting tube, L and the air, entering the filter K and, circulating in the 39 air-gap 54, to pass with the said steam through the medicine contained in receptacle N, the conical partitions o1 o2 o3 o4 and the return valve y1 to the flexible pipe Q and mouth-piece R. In some cases the flexible pipe Q will preferably be provided with a water receptacle q, fixed to an intermediate pipe Q1 inserted substantially in the middle 35 of the length of the said flexible pipe Q. as shown in Figure 4. In a modified form of the medicine-tube N1 Figure 5, intended to replace the perforated tube M of Figure 1, the outer tube thereof is combined with a con¬ centric inner tube nl and with a cover A2 having suitable openings n2. The medicine is placed between the tubes W and n1 and the steam entering the latter 49 as shown by the arrow 1 is thrown back by the cover N2 upon the said medicine and then escapes through the openings n2 into the vertical tube 0 in the manner above described with reference to Figure 1. Figure 6 shows how the tube Gf may be arranged when the vapours escaping from the infusing apparatus F are to be mixed with a pulverized liquid. ^ 4 - The said tube G is then combined with a suction pipe G1 dipping into a glass I1, containing the liquid medicine and placed in the drip-cup I. This device works in the well-known manner for inhaling steam and a pulverized liquid. In a modified form of condensed steam pot or receptacle S the latter is provided with several openings s over which a screen s1 figure 7 is arranged, the purpose 59 of which is to control the openings s. These openings are intended to*allow the steam which may enter the pot S to escape. Having now particularly described and ascertained the nature of my said inven¬ tion and in what manner* the same is to be performed, as communicated to me by my foreign correspondents, I declare that what I claim is: — 1. A double-working inhaling-apparatus, characterized by the combination of a 55
