To all whom it may concern.-

Be it known that I,ADOLF LUnvIG LoN- NERBERG, a subject of the King of Sweden and Norway, residing at 8 Kungsholmsgatan, in the city of Stockholm, Sweden, have invented certain new and useful Improvements in Inhaling Apparatus, (for which patents have been granted in Sweden, No. 3,797, dated December 12, 1891, and No. 3,829, dated March 18, 1892; in Belgium, No. 98,992, dated March 28, 1892; in Norway, No. 2,614, dated March 23, 1892; in England, No. 5751, dated March 23, 1892; in France, No. 220,576, dated April 1,1892; in Switzerland, No. 4,999, dated April 6,1892; in Germany, No. 67,7l7, dated March 22, 1892, and in Austria-Hungary, No. 36,281 and No. 14,082,dated March 12, 1893,) of which the following is a specification.

This inhaling apparatus is principally intended to be used for the curing of any. afiection of the chest when a certain gas or gases or mixture of gas and air is to be inhaled,'the

apparatus being therefore so arranged that the relation between the air and the gas may be easily regulated. It may, howevenalsoj be used for inhaling air alone, for instance,

when it is desired to'have the air to be inhaled heated or purified.

The apparatus is of such dimensions that the person using same can carry'itabout: while at the same time the gas is being de-- vote any attention to the apparatus nor is he inconvenienced thereby.

The apparatus consists essentially of a bottle or vesselcontaining the material or.liquid from which the gas is to be generated, absorbed in a sponge, or in some solid, porous material, forl instance charcoal, or it may be in liquid state. Into the bottle there descends a tube, provided within the bottle with an adjustable valve, through which the gas can ascend the tube, and at the outer end of whichthere is fixed a shield provided with valves and intended to be placed in front of the mouth. Through other valves the at- "mospheric air is drawn into the tube or the; bottle, the'se valves being likewise adyustablev so that the air arrives in the tube and the bottle at the same time in the same or in different proportions, or only in one of them at the same time. As to the passage of the air, this may be arranged in various ways. In the annexed drawings several constructions therefor are represented, which however do not differ from each other materially.

In'the said drawings-Figure 1, is a sectional elevation'of-an inhaling apparatus embodying my improvements. Fig; 2, is a similar view illustrating another .form of the apparatus. Fig. 3 is a similar view of another form. I i Fig. 3 is a sectional plan of the upper part ofthe apparatus seen in Fig. 4:. Fig. 4 is a; sectional elevation of another form of the apparatus. Fig. 4* is a detail sectional plan the plan of the section being through the neck of the generator vessel seen in Fig. 4. Fig. 4* illustrates details which will be described.

Referring to Fig.1 A designates a bottle inclosing a sponge, B,- containing the material from which the gas is to be generated. Into thezbottle there descends, through the neck thereof, a pipeiO,i,containing a pipe D, which extends'farther'down into the bottle and is closely embraced by the lower end of the pipe .O. I On the lower end of the pipe D is fitted iazcap, G, provided with a lateral opening H. The latter, through which the gas generated inthe bottle enters the pipe D, can be made elastic collar L, fitted over the neckof the. bottle, and the size ofthe opening E can be regulated by means of an adjustable collar F on the pipe 0. The atmospheric air may likewise be let into the bottle. For-this purpose there is a :hole .A' in the neck of the latter, which hole can be closed or left more or less open by movinga rubber ring A up;

ward or downward on the neck of the bottle. Finally the top of the pipe D is provided with avalve 1 opening toward the tube. If required to have the air to be inhaled only slightly mixed with the gas from the bottle, the hole A is closed and the cap G is adjusted so that the hole H is suificiently open. When inhaling, the atmospheric air flows into the tube through the hole E and there suction takes place just as with an ordinary ejector in the pipe D. The gas and air are mixed in the tube and are inhaled through the valve P. The exhalation takes place through the valve 0. If the hole H be further opened, more gas will enter the pipe D, and if the hole A be also opened and the hole E closed, the air inhaled will be still more mixed with gas, inasmuch as the atmospheric air, during the inhalation will then rush into the bottle and cause some pressure, wherefore gas and air will flow up into the tube in an active manner. It is thus possible to regulate the mixing of the air inhaled with gas with great exactitude.

In Fig. 2 the apparatus is represented somewhat simplified. The tube M here descends directly into the bottle through a sleeve-like stopper M, inserted in the neck of the bottle, this stopper being provided with a lateral opening as is also the tube, and both of these lateral openings may be regulated by turning or displacing the tube and the sleeve in relation to one another. This regulation can, however, be eifected in many other ways, for instance by causing the lateral opening of the tube to project more or less above the top of the sleeve, and the sleeve may consist of a pierced cork, or the tube itself may be closely fitted into the neck of the bottle. Into the lower end of the tubeM there is inserted a small, closed glass tube or cap D, and by pushing this tube more or less into the tube M, the lateral openings D D of the latter may be left more or less open. If the tube M consists of such a material as may be alfected by the contents of the bottle, the end of the same entering into the bottle may be made of glass. The mouth shield is likewise simplified, as instead of the above described valve P, a small rubber plate, P, is fixed outside of the shield and covers an opening in the latter and instead of the valve 0 the small flap O is used inserted in the tube. The shield may be maintained in place in front of the mouth of the patient by elastic string or straps round the head. These are not shown.

Figs. 3 and 3 show the apparatus so arranged that it may be used either in the way described, or for heating the airto be inhaled, with or without simultaneous mixture with gas. Into the bottle there descends the curved end of one or more U-shaped pipes, B, one end of each of which rises through the stopper and the other ends enter into a cham ber R in the stopper. A tubular nipple, S, is inserted into the chamber R, and to this nipple is connected the inhaling tube. The

nipple S may be inserted as shown by the full lines, or as shown by the dotted lines; that is, either horizontally or vertically. Adj ustable valvesa cover the outer ends of the pipes R, and the atmospheric air can also enter the bottle through another channel a, traversing the stopper, and which can likewise be closed more or less by means of a valve 5. Within the bottle and in the pipes there are holes 0 so that the gas generated in the bottle may enter the pipes and pass into the tube. For persons suffering from phthisis theinhalation of hot air has proved useful. This ought then to be so'much the more the case, if the air were mixed with some gas known to act benefically upon the lungs. The apparatus Fig. 3 is very well adapted for introduction of this kind. The bottle is placed in a vessel containing hot water or steam so as to be heated. The air passing into the apparatus through the valves a will thus be heated when passing through the pipes and in order that the air may be speedily heated and as little resistance as possible occur in inhaling, several pipes are inserted among which the passage of the air is distributed. Through valves b the atmospheric air may be let into the bottle with the view already stated.

The form of apparatus illustrated in Figs. 4 to 4 difiers from that last described substantially only in that both ends of the U- shaped pipe or pipes R pass through the stopper and that the tube M is connected directly to one end .of the pipe. If several pipes be used (the figure shows two) the ends of the pipes may be coupled together by means of a branch pipe 013, Fig. 4 with which the tube M is connected. The opposite ends of the pipes R are covered by adjustable valves a as in Fig. 3 and within the bottle there are holes in the pipes so that the gas may enter the same. The tube Figs. 3 and 4, is provided with lateral openings as at E Fig. 1, in order that the air may pass directly into the same, when it is not required to let the air pass through the pipes R the opening in the tube being, on the contrary closed, if the air is to go through the pipes. The apparatus Fig. 4, may also be used for the inhalation of heated air and with or without the addition of gas generated in the bottle. If heated air only is to be inhaled one has only to close the holes {0 and the valve 1) so that no gas may enter the pipes and air only enters the latter. In lieu of the hole A in the neck of the bottle Fig. 1, or the channel a, Fig. 3, there can evidently be a hole in the body of the bottle covered by an adjustable valve plate. Such a valve A is shown on the apparatus in Fig. 4:. In lieu of the bottle A it is evident any other suitable vessel may be used.

The apparatus described may also be used for purifying the air to be inhaled. The bottle is therefore fitted with a filter, for instance made of cotton, with or without addition of other material depending upon the too nature of the air, and the air is caused to enter the bottle through the valves A a and the pipe or pipes through the valves 0. The air will then be purified during its passage through the filter. In lieu of a mouth shield the tube M may be provided with a mouth piece of any other description found to be convenient.
