NAsAL GUARD.

I Specification of Letters lPatent.

Patented Ndv. 19, 1912.

Application filed June 7, 1912. .Serial No. 702,370.

To all whom it may concern:

Be it known that I, JOHN W. REDDY, of (reneva, in the county of Ontario, in the State of New York, have invented new and useful improvements in Nasal Guards, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to nasal guards and pertains more particularly to that class of nasal guards comprising two elliptical sections adapted to be inserted in the nostrils and connected by a yoke or any resilient strip of material.

Nasal guards of this kind are particularly useful in factories, foundries and machine shops, where the air is heavily laden with dust, and especially when the dust is comprised of metal or emery particles in urious to the human system, to prevent the inhalation of the foreign matter suspended in the air. and likewise inhaling hay fever germs.

The object of my invention is to produce a nasal guard which shall be .of inexpensive and simple construction, adapted to be readily taken apart to be cleaned, and in which the only destructible part is readily removed and replaced and firmly held in position by the tension of a surrounding rim.

A further object is to reduce to a minimum the liability of the guard becoming clogged by the dust and dirt.

Having the above objects and uses in mind, my invention consists 1n the new and novel features of construction hereinafter described in connection with the accompanying drawings, forming a part thereof, in which Figure l is a top plan View of my nasal guard. Fig. 2 is a cross section upon line 22, Fig. 1. Fig. 3 is a view of the blank from which my nasal guard is formed. Fig. 4 is an'enlarged detail view showing one of the air passages and the projecting flanges 8 formed around the edge thereof.

1 is a frame preferably as shown in Fig. 3, pressed from a single strip of metal and adapted to form the elliptical rings 2, split upon one side and having the ends 3 and 4-- turned in and bifurcated. The rings 2- have other integral projections as 5-, bent so that they extend radially of the ring.

By slightly spreading the ring -2 the plate 6, having upon one side a covering of gauze material 7-, is readily placed in the ring and between the bifurcated portions of the ends, the edge of the gauze7- being held firmly between. the plate 6 and the ring 2.

The projections -5- and the bifurcated portions of the ends -3 and A-- hold the plate 6 and the .gauze -7 with which it is covered firmly within the ring 2. The plates 6 are each provided with a plurality of openings -9, punched through from one side to form a projecting rim -8 around each opening. The plates 6- are then placed in the rings '-2- so that these projections are upon the lower side when the device is in operable position, and upon this lower side is placed the gauze covering 7--. This projecting rim -8 holds the gauze from contact with the plates 6- and prevents clogging of the guard.

The rings -2 are connected by a yoke 10- preferably formed integral therewith but it is readily apparent that it may be formed separate from the rings and connected thereto in any suitable manner withoutdeparting from the spirit of my inven tion.

What I claim is:

1. A nasal guard comprising two resilient split rings connected by a yoke, lateral projections on said rings, a perforated plate adapted to fit in each of said rings and a dust intercepting material covering each of said plates and extending between the edge of the plate and the surrounding ring and held therein by the lateral projections on said ring.

2. A nasal guard comprising two resilient split rings connected by a yoke, lateral projections on said rings, a perforated plate positioned in each of said rings, gauzematerial covering each of said perforated plates and retained in engagement with the lateral projections by the tension of the surrounding ring.

3. A nasal guard comprising two elliptical rings connected by a yoke, each of said rings split across one side and the ends adjacent the split inturned and bifurcated, integral projections on said rings, a perforated plate in each of said rings and lying between the projections formed by the bifurcated ends and held in place by the projections on the rings.

4. A nasal guard comprising'rings connected' by a yoke, a plate having openings therethrough positioned in each of said rings, projecting flanges around each of said openings upon one side 'of said plate, and a gauze material lying on said projecting flanges and held in place between the plate and the ring. 5. A nasal guard comprising a frame, a perforated plate operably held in the frame, projecting flanges around the perforations upon one side thereof and a gauze material operably positioned over said openings. 6. 'In a nasal guard, a plate having a plurality of openings therethrough, projecting flanges around said openings upon one side of the plate and a dust intercepting material resting upon said flangesand covering the 15 openings.

7. nasal guard, comprising resilient split rings, ends adjacent the split inturned and bifurcated and a plate positioned in, each of said rings and between the bifur- 2 cated portions of the ends. a

In 'witnesswhereof I have hereunto set my hand on this 27th day of May 1912.
