INHA'LER AND EXHALER.

Patented Feb. 27, 1906.

Application filed June 27, 1904. Serial No. 214,304.

To all whom it may concern:

Be it known that I, JOHN LAWRENCE HILL, a citizen of the United States, residing at the city of Jackson, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in Inhalers and Exhalers, of which the following is a specification.

This invention relates to improvements in inhalers and eXhalers.

The main object of this invention is to provide an improved inhaler and eXhaler which is simple and economical in structure and convenient to use.

Further objects and objects relating to structural details will definitely appear from the detailed description to follow.

I accomplish the objects of my invention.

by the devices and means described in the following specification.

The invention is clearly defined, and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawings, forming a part of this specification, in which Figure 1 is an elevation view of my improved inhaler and eXhaler. Fig. 2 is a longitudinal sectional view thereof, taken online 2 2 of Fig. 1. Fig. 3 is a cross-sectional view taken on a line corresponding to line 3 3 of Fi 2.

In the drawings the sectional views are taken looking in the direction of the little arrows at the ends of the section-lines, and similar letters of reference refer to similar parts throughout the several views.

Referring to the drawings, the inhaler member A and the eXhaler member A are tubular or hollow and are internally screwthreaded at their inner ends. A threaded coupling A is provided. This coupling also seals the inner ends of the two members. The two portions are preferably of uniform size, so that when secured together they present a uniform appearance. The inhaler member is provided with a nasal tip at its outer end and the exhaler member is provided witha mouthpiece or tip at its outer end.

The inhaler A is provided with transversely-opening inlet-ports a at its inner end, and the eXhaler portion A is provided with a transversely-opening reticulated deliveryport a. at its inner end. The chamber in the inhaler member A is filled with a suitable material B, such as absorbent cotton, adapted to absorb a medicament, so that the air inhaled therethrough is suitably medicated. A removable perforated disk-like partition B is provided to retain the medicated material in place. This partition-plate is arranged within the ports, so that it also prevents the clogging of the same.

In inhaling, the nasal tip is used and the air passing through the medicated material B is suitably medicated. The air is also freed from any dust or the like. The mouthpiece or tip is then placed in the mouth and the air exhaled therethrough. As the delivery-port a is of comparatively small dimension, considerable force is required in expelling the air. This brings the muscles of the lungs into action, and themedicated air is forced through the lung-cells, opening and exercising the same and at the same time carrying the medicament therethrough.

My improved inhaler and eXhaler is very compact in structure and convenient to use. It is also attractive in appearance and possesses the further advantages of being economical to produce and durable in use.

I have illustrated and described my improved inhaler and exhaler in detail in the form preferred by me on account of its structural simplicity and economy, although I am aware that it is capable of considerable structural variation without departing from my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a device of the class described, the combination of a hollow inhaler member having inlet-ports in the walls thereof and internal screw-threads; a hollow eXhaler member having a restricted delivery-port and internal screw-threads; a threaded coupling for said members adapted to seal their inner ends a filling for said inhaler member adapted to receive a medicament; and a removable perforated partition for said inhaler member, for the purpose specified.

2. In a device of the class described, the combination of a hollow inhaler member having inlet-ports in the walls thereof and internal screw-threads; a hollow eXhaler member having a restricted delivery-port and interhaler member having a mouthpiece at its outer end and a restricted delivery-port; and a coupling for the inner ends of said members, for the purpose specified.

4:. In a device of the class described, the

combination of an inhaler member having a nasal tip at its outer end and inlet-ports at its inner end, and a receptacle for medicament; an exhaler member having a mouthpiece at its outer end and a restricted deliverypot; and a coupling for the inner end of said members, for the purpose specified.

In Witness whereof I have hereunto set my hand and seal in the presence of two Witnesses.

VERNE W. BADGLEY, FREDERICK L. CHILDs.
