INHALING APPARATUS.

To all whom t may concern.-

Be it known that I, ALFRED JOHANNES \VASSMUTH, of Barmen, in the Kingdom of Prussia and German Empire, have invented a new and useful inhaling Apparatus, (for which I have received Letters Patent in France, No. 199,493, dated July 10, 1889; in Belgium, No. 86,952, dated July 11,1889, and in England, No. 14,562, dated September 1G, 1889,) of which the following isa specification, reference being had therein to the accompanying drawings.

This invention relates to a new or improved inhaling apparatus `in which the pharmaceutical solution used joins the air of the room .in such a way that while the air is thoroughly impregnated no visible precipitates appear.

The method of working the apparatusis as follows: The pharmaceutical solution is forced by means of a pump into the inhaling apparatus, which is provided with a diffuser or spraying device, and it issues from the apparatus in the form of a fine cold vapor, which is discharged in the room along with atmospheric air drawn in through apipe connected with the diffusing device. The fresh air becomes intimately mixed with the medicated vapor. The principal novelty of the arrangement is that the air which joins the pharma ceutical solution is taken from the atmosphere instead of from the room in which the solution is being diffused. Openings are preferably made through the lower part of the walls or the door of the room in which the inhaling apparatus is placed, so that when the fresh air, which is impregnated with pharmaceutical solution and is heavier than the air being used in the room, is admitted it will press the Vitiated air out through the openings in the floor or walls. The inhaling apparatus is so constructed that'any liquid not quite vapor-ized will be conducted back again into the receptacle of the pharmaceutical solution.

The apparatuses used are reprcsei'lted on. the drawings annexed, whereon- Figure 1 shows the arrangement of the apparatus as used for inhaling. Figs. 2 and 3 show in part section and plan the interior construction of the apparatus for diffusing the medicated vapor. Fig. L shows in part section a modified construction of the same.

-The arrangement for inhaling, as represented at Fig. 1, is as follows: A pump a, moved by any mechanical power, forces the pharmaceutical solution under a pressure of from five to seven atmospheres out of the vessel I), which is filled through the funnel c, through the piped to the diffusing or dissipatingapparatus e. The solution issuing through the spraying-nozzle CZ', Fig. 2, impinges against the apex of the cone c and is forced outward toward the space oropening g around the diffuser, from whence it issues in the form of a cold vapor. At the same time a constant stream of fresh airis inducted through the pipeffrom the outer atmosphere. This inducted air combines and issues along with the medicated vapor. The quantity of fresh air admittedto the room in this manner would be seven hundred to eight hundred cubic meters per hour. The viti ated air expired by the patient will be pressed downward and out through the holes 7.: in the walls. In this way the air will be renewed ten to fifteen times a day, according to the size of the room, and this renewal will take place without perceptible draft. As there is such a constant and thorough renewal of air, any number of patients maybe allowed toinhale at the same time in the room without the air being seriously deteriorated. The patients inhale the impregnated air quite naturally. They may sit, lie, walk about, or even sleep while the pharmaceutical solution along with the air will enter their lungs. Any condensed or superfluous solution collects in the bottom 7i of the dilfuser e and iiows through the pipe 1T back to the vessel l).

The inhaling` apparatus used in Fig. l is shown on an enlarged scale at Figs. 2 and 3, where, as before described, the pharmaceutical solution is forced through the pipe d. to the diffusing apparatus, where it impinges against the conical diffuser and is divided into minute particles, which combine and issue with the atmospheric air at g. The pipe fconducts the air from outside the building into the case of the distribnter or diffuser.

The apparatus represented at Figs. 2 and 3 IDO may be modified, as shown at Fig. 4. In this View Fig. 4 the dissipating` apparatus consists of a case a', made of any material, and Which is connected with the outside air by 5 the pipe b. Between the case a and the pipe b there is a knee or bend, the object of which is to collect any superiiuous or condensed liquid and allow it -to pass back through thepipe d to the forcing-pump. The spray-nozzle e', which is connectedlwith the force-pu mp by the pipe f enters the vertical part c2 of the pipe above the bend. When using the apparatus the liquid is forced under considerable pressure along the pipe f in the direction of the arrow and through the spray-nozzle e'. As itissues' from nozzle e', it strikes against the walls of the funnel g, and the conical cap h', driving at the same time the fresh air through the funnel g. The zo large particles of the solution drop down to the bottom of the Siphon-bend, so as to be carried away by the pipe d back to the forcepump, while the fine particles of the solution are forced out of the apparatus at z" by the upward rush of ain After the apparatus has been started, the room is soon filled with the Vapor, and the air in the room becomes like mist. The solution combines with the air so thoroughly that no perceptible precipitation 3o takes place. Vhen used for disinfecting purposes, the apparatus gives these advantages, viz., it delivers the disinfectant in a Very finely-dried state and distributes itint'o every corner of the room.

Of course no broad claim is made by me to the medication of air per se, as this has long been practiced.

What I claim, and desire to secure by Let- -ters Patent of the United `States, is-

vice, and a fresh-air-supply pipe jconnected with the diffuser, all substantially as shown and described.

2. In combination with air-pump aand reservoir b, the diffuser e, connected with the pump, a fresh-air-supply pipe f, also connected with the diffuser, and a pipe t', extending from the diffuser back to the reservoir b,

substantially as and for the purpose exlplaiued.

In witness whereof I have hereunto set my hand in presence of two witnesses1 ALFRED JOHANNES WASSMUllI.
