IN HALING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 506,368, dated October 10, 1893.

Application filed .April 10, 1893. Serial No. 469.785. (No model.)

T0 all whom it may concern:

Beit known that jI, OLE E. O. I-IOELL, a subject of the King of Sweden and Norway, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Inhaling Apparatus, of which the following is a specification.

My invention relates to an improvement in applying vaporizedliquid medicament in a more or less dry atomized state for the relief and cure of catarrhal, pulmonary and other diseases; and my object is to provide an apparatus of the above class of an improved construction which shall render it particularly desirable for all the purposes for which it is intended. v

In the drawings-Figure l, is a view of my partly in section, the section being taken on line l-l of Fig. 2, and viewed in the direction of the arrow; Fig. 2, a section taken on line 2 of Fig. l; Fig. 3, a plan sectional View taken on line 3 of Fig. l; andFigs. 4 and 5 sections taken respectively on lines 4 and 5 of Fig. 2, and viewed in the downward direction.

A is the inhaling apparatus,and B an atomizer of the construction I prefer to employ. The lower or stand portion of the inhaling apparatus is preferably of metal cast in one piece, and comprising a base t, a drum-portion s, and an upper rim-portion fr'. The drumportion affords a lamp chamber s', and it is provided at one side with a large opening s2, to permit ready insertion and withdrawal of a spirit lamp q. In the rim-portion r is a seat r for a preferably dome-shaped cap p. The cap p may be a plate provided with numerous perforations, though it is preferably formed of wire gauze, as shown. Around the cap p above the seat r is a seat r2 for a preferably glass cylinder naffording a spray chamber n. The cylinder n is expanded,as shown at n3, to enlarge the chamber in the horizontal plane. The cylinder n may be formed of an ordinary lamp chimney, and itis fastened upon the seat r2 by means of thumb screws r3. Fitting over the top of the cylinder fn. is a preferably metal cap piece m, bent, as shown, to the horizontal plane, and provided with a reduced opening m at its end. At

one side of the drum s is a bracket s3, and removably fastened to the bracket is an atomizer stand Zsurmounted by a cup-shapedv receptacle Z.

The atomizer B comprises a bottle-shaped receptacle @which tits into the cup Z', and is held therein by springs Z2; an atomizing chamber lo having a tubular extension k2 fitting like a stopper into the neck of the bottle la; and a tubular extension k3. A flexible liquid-tube t' extends through the stopper-portion k2 from near the base of the bottle'k to about the center of the atomizing chamber. Around the tube and leading from the chamber k to the interior of the bottle through the stoppereportion k2 are one or more passages i. The blast tube h of the atomizer extends through the part k3. The spout lo? of the atomizing chamber comprises a tube of gradually decreasing diameter smallest at the discharge end, at which it tits into an opening n2 in the cylinder n. The blast is furnished by means of rubber bulbs gin the usual way.

In operation, the bottle lo is filled with the medicine' .to be sprayed, and the lamp q is ignited. The atomizer B is then operated to discharge the medicinein the form of a spray into the chamber n. The lamp q causes heated air currents to rise through the cap p into the spray chambern and the currents -of heated air operate to'decompose the liquid portion of theimedicine and carry the more or less dry particles thereof to the outlet fm. The nozzle 154 terminates just within the opening n2 in the extended part of the chamber fn', and the vaporized medicine is sprayed in the horizontal plane across the chamber. The vapor from the nozzle 7a4 thus becomes thoroughly mixed with the heated air in the expanded portion of the chamber, and is freed of the greater part, at least, of its moisture.

The cap p operates von the principle of the Davy lamp to shield the medicine sprayed into the chamber fn. from contact with the ame of the lamp. Thus if the medicine is of a nature which might become ignited or be exploded by contact with the flame, the perforated cap 1o will obviate any such danger. The cap also operates to spread the hot air currents and cause them to rise equally throughout the spray chamber.

Constructed as shown and described, the

IOC

5 device,and it aiords a particularly safe, convenient and desirable apparatus for the application of vaporized medicine in a more or less dry form.

What I claim as new, and desire to secure 1o by Letters Patent, is-

1. In an inhaling apparatus, the combination of the lamp chamber s', spray chamber n above the lamp chamber, perforated cap between the said chambers, and an atomizer x5 B provided with a nozzle 7a4 extending into the spray chamber, substantially as described.

2. `In an inhaling apparatus, the combi11ation of the lamp chamber s', a perforated cap on the lamp chamber, a spray chamber n zo having the expanded part n3, provided with an opening n2 and curved and reduced upper portion m, and an atomizer B having the discharge nozzle 7a4 extending into the opening n2 and terminating at one side of the expanded port-ion n3 to discharge the vapor across the chamber n', substantially as de scribed.

8. In an inhaling apparatus, a metal stand portion comprising a base t, a drum s having an opening s2 and aording a lamp chamber, and a rim raffording seats r r2, a perforated metal cap p on the seat fr', a cylinder fn affording a spray chamber having the expanded portion ns and an opening 'n2 at one side of the expanded portion, a curved cap piece m on the cylinder and an atomizer B provided with the discharge nozzle 704 extending into the opening n2, substantially as described.
