Nasal inhaler.

Application filed April 1,1903. Serial No. 150,620. (No model.)

To all whom it may concern:

. Be it known that I, Charles K. Teter, a citizen of the United States, residing at Upper Sandusky, in the county of Wyandot and 5 State of Ohio, have invented new and useful Improvements in Nasal Inhalers, of which the following is a specification.

My invention relates to nasal inhalers, and has for its object to construct a device for io administering gas through the nose.

The simple and novel construction employed by me in carrying out my invention is fully described in this specification and claimed, and illustrated in the accompanying 15 drawings, forming a part thereof, in which—

Figure 1 is a perspective of my device. Fig. 2 is a longitudinal section thereof. Fig. 3 is a transverse section thereof.

The numeral 1 designates a cup formed of 2c stiff rubber and having its edges rounded off on a compound curve to adapt it to fit over the nose of the patient and rest on the upper lip and the bridge of the nose. The cup 1 is mounted in a metallic cup 2, having an aper25 ture 3 therein to accommodate an open thimble 4, provided with a rim 5 on one end and threaded at 6 on the other. The rim 5 engages the edge of an aperture l^a, formed in the cup 1, and a threaded cap 7 fits the threads 30 6 and clamps the cup 1 firmly in place. The cap 7 is perforated at 8 to permit exhalation, and a plunger 9 is inclosed within the cap and has a stem 10, which is slidingly mounted in an aperture in the top 11 of the cap 7 and 35 bears an adjustable head 12, which limits the inward movement of the stem. A springTS bears on the plunger and holds it normally depressed and in position to limit the upward movement of a thin disk 14, which fits over 40 the bore in the thimble 4 and serves as a valve to permit exhalation, but prevent inhalation.

To enable a flexible tube to be attached to the inhaler, a nipple 15 is provided which fits over a thimble 16, bearing a rim 17, which 45 engages the inner edges of an aperture 17^a, formed in the cup 1. Yokes 18, attached to opposite sides of the cup 2, serve as attachments for elastic bands 19, secured together by a buckle 20. When in use, the cup 1 is placed over the nose and the bands 19 passed 50 around the head and secured by the buckle * 20. A flexible gas-tube is then slipped over the nipple and the gas turned on.

I do not wish to be limited as to details of construction, as these may be modified in 55 many particulars without departing from the spirit of my invention.
