WAYLAND D. STEARNS, 7 OF DETROIT, MICHIGAN, ASSIGNOR TO FRED- ERICK STEARNS & COMPANY, OF DETROIT, MICHIGAN, CORPORA-- TION or MICHIGAN.

l N HALER.

To aZZ whom it may concern:

Be it known that I, WAYLAND D. STEARNS, a citizen of the United States, residing at Detroit, in the county of IVayne and State of Michigan, have invented certain new and use ful Improvements in Inhalers, of which the following is a specification, reference being bad therein to the accompanying drawings.

The invention relates particularly to inhalers of the portable or pocket type-containing a medicament for the cure of catarrh and kindred ailments or such other inhalant as may be desired; and it consists in the novel and simple constructionofthe inhaler and in the peculiar arrangement and combination .of

, its parts, as will be more fully hereinafterset forth.

In the drawings illustrating my invention, Figure I is avertical central section through the inhaler. Fig. 2 is adetached perspective view of the closures and their connecting member, and Fig. 3 is a perspective view of the casing which forms the body of the inhaler.

In the drawings thus briefly described, A represents the casing, preferably of glass and of cylindrical form, open at each end, as illustrated, and having one end, as a, tapered topermit of its application to the nostril of the user.

The reference-letters B and C designate closures for the opposite ends of the casing,

adapted to be adjusted so as to permit air to be drawn through the inhaler when in use and to seal the casing ends when not in use to protect the medicament. The closure B is preferably in the form of a conical plug ar- I ranged within the tapered end of the casing and. secured to the outer extremity of the spindle D, which forms an operative connection between the closures. The closure is preferably sectional in form, comprising an In Fig. the inhaler is illustrated as in readi- Specification of Letters Patent. I Application filed October 29, 1904. Serial No. 230,56;-

ness for use, the air being capable'of passing through the apertures cand f'ofthe closure G, around the plug or valve B, and out through the tapered end a. To seal the inhaler, a roe tary and longitudinal adjustment is given to the outer cap member d by screwing it upon the inner cap, which movement causes the two caps to contact, the apertures being out of alinement, and the closure B to engage the tapered walls of the casing, thereby sealing that end.

When it is desired forany reason to remove or replacethe-absorbent material about the spindle, this may be effected by first removing the inner cap 6 and then drawing the absorbent material from out the casing. To recharge the inhaler, it is merely necessary to unseal the ends in the manner described and by inserting a suitable charging instrument through the apertures in the sectional cap moisten the absorbent material With the desired medicament.

It will be obvious from the description of my invention that the inhaler is of exceed- I ingly simple construction, permitting it to be manufactured at small cost, and that the parts may be readily assembled and the inhaler easily recharged when desired.

Y What I claim as my invention is 1..In an inhaler, the combination with an open-ended casing, of a closure for one end thereof comprising two apertured and relajoining the latter closure with the adjustable cap member.

.2. In an inhaler, the combination, with an open-ended casing, of a. sectional closure for one end thereof, both parts or members being aperturedand one being mounted for rotary and longitudinal adjustment relative to the other, a closure for the opposite end, and a connection between the latter closure and 3. -In an inhaler, the combination with an open-ended casing, of an inner apertured cap closing one of its ends, an outer apertured cap having a threaded engagement with the inner,- a closure for the opposite end of said casing, and a spindle passing through the in- 'tively adjustable cap members, aclosure for .the opposite end, and a connecting member ner cap and connecting the outer cap with the v closure.

4. In an inhaler, the combination, with a casing tapered at one end and open at both, of a closure for and arranged within the tapered end, a sectional closure for the opposite end, the sections being each apertured and relatively adjustable longitudinally, and a connection between the closures compelling upon the adjustment of one a corresponding movement of the other.

5. In an inhaler, the combination With an open-ended easing, of a closure for one end thereof, a two-part closure for the opposite end, both of said parts being apertured and one being adjustable, and a connection between the closures compelling upon the adjustment of one, a corresponding movement of the other.

6. In an inhaler, the combination with an open-ended casing, of a closure for one end thereof, a two-part closure for the opposite end comprising an apertured inner part inclosed by an apertured outer part, and a connection between the closures compelling simultaneous adjustment.

In testimony whereof I aflix my signature in presence of tWo witnesses.
