THESDIE F. FELTNEB, OF BOISE, IDAHO.

INHALER AND DUST-PROTECTOR.

Specification of Letters Patent.

Patented Mar. 18, 1919.

Application filed January 4, 1916. Serial No. 70,244.

An object of my invention is to provide protector comprising a shield member which may be fitted in place over the mouth or nostrils, or both, and which has a space to receive wool or other filtering material so that upon each breath, the air will be strained and filtered, and if a medicament be applied to the filtering material, the air will carry the said medicament into the lungs in the form of a. vapor.

A further object is to provide means to secure the shield in place, which means is constructed to permit adjustment to adapt the device for use by various persons.

With other objects in view, my invention consists in certain novel features of construction and combinations of parts which will hereinafter be set forth in connection with the accompanying drawings and then pointed out in the claim.

In the drawings:

Figure 1 is a View showing the manner in which the device is applied and held in place.

Fig. 2 is a view in elevation of the shield.

Fig. 3 is a view looking into the shield.

Fig. 1 is a detail view of the means by which the securing cord may be adjusted.

Fig. 5 is a plan View of a modification which may be resorted to in connection with the shield.

In the form illustrated in Figs. -1 to 3 inclusive the shield 1 may be constructed of aluminum, hard rubber, or other suitable material. This shield is cupped out to form a filter chamber which is preferably made of substantially elliptical form the edges of the cupped portion rolled over as at 2, and shaped to fit against the face over the nostrils and mouth, as is better illustrated in Fig. 2.

The cupped portion 3 of the shield has th perforations 4c formed therethrough to permit the supply of air to the interior of the shield and to also permit the escape of air therefrom. and if desired, a cross piece 5 may be disposed between the top and bottom sides of the cupped portion adjacent the rolled edge to aid in retaining the-wool or other filter material indicated at 6 in Fig. 3.

'With the parts arranged in the manner hereinbefore set forth, the rolled edge 2 of the shield member may be fitted against the face over the mouth, the nostrils, or both, and as all air taken into the lungs must pass through the perforations 4 and consequently through the wool or other filtering medium shown at 6, the air will be strained and filtered of impurities before being taken into the lungs,

and also the breath passing from the mouth and the nostrils will cause the fibrous filtering medium to be warmed and as the next breath is drawn in through the shield the air will be warmed and brought to a temperature more nearly approximating the temperature of the body than does the temperature of the atmospheric air.

, As a means of securing the shield in the proper position, the spring clips 7 are provided to be received over the ears and at their forward ends have the eyes 8 provided. A cord 9 is passed through an opening 10 on each side of the shield 1, and these cords are led through the eyes 8 of the spring clips 7 and are brought back to be secured with the s-shaped adjusting members 17 which are received around the main extent of the cord 9. In fitting the shield to be secured in place, the shield 1 is positioned at the proper point, the spring clips 7 are fitted over the ears, and the adjusting members 17 are then moved to bring the cords 9 to the proper tension, these adjusting members 17 being in engagement with the body of the cords 9 to bind sufficiently to retain the adjustment thus made.

The filtering medium 6 has been referred to as wool or an equivalent substance, but when occasion requires this material might be one which would have medicinal properties or the wool or other filter material may be saturated with a medicament which will be taken up by the air passing therethrough and will pass with the air into the lungs, in the form of a vapor.

While I have herein shown and described only specific forms of the invention, it will be understood that the cord 9 might be an elastic cord, that the shield portion might be constructed of celluloid or some other material not herein described, and that other modifications might be resorted to in materials used and in the construction and combination of parts Without departing from the spirit and {scope of my invention,

. and hence I do not Wish to be limited to the exact invention herein illustrated, but only to such points as may be set forth in 'the claim.

I claim:

v In an inhaler and dust collector, the combination of a perforated body portion, said I body portion being longitudinally channeled of, a Washer resting upon said rim, said 15 Washer being curved throughout its entire length to conform to the contour of the rim, said Washer being provided with openings, said bar reinforcing said washer, intermediate its ends, and retaining means connected to said body portion.

In testimony whereof I afiix my signature 1n presence of two witnesses.

THESDIE F. FELTNER.
