Respirator.

Application filed. August 31,1912. Serial No. 718,043.

To all whom, it may concern:

Be it known that I, Robert Armour Myles, a subject of the King of Great Britain, and resident of the city and dis5 trict of Montreal, in the Province of Quebec, Dominion of Canada, have invented certain new and useful Improvements in Respirators; and I do hereby declare that the following is a full, clear, and exact descrip10 tion of the same.

The invention relates to improvements in respirators, as described in the present specification and illustrated in the accompanying drawings that form part of the same..

The invention consists essentially in the novel means employed, whereby the nostrils of a person are maintained in free and open position.

The objects of the invention are to devise 20 a means to facilitate the breathing of an individual, especially during a stressful time, to furnish a very simple respirator for persons suffering from diseases of the lungs, to provide a simple device for athletes 25 to relieve the contraction of the nostrils incident to great exertions and generally to simplify and cheapen the manufacture of such articles and bring it within the reach of all consumers.

In the drawings Figure 1 is a perspective view showing the respirator as applied. Fig. 2 is an enlarged perspective, view of the respirator.

Like numerals of reference indicate corre35 spoil ding parts in each figure.

Referring to the drawings 1 and 2 are the prongs inclined slightly toward one another and bent in easy curves at the lower ends and extending inwardly and overlapping 40 and having at their extreme upper ends the lobes 3 and 4 on the outer sides, said .lobes being formed of silver or other suitable material, that will in no way injure the nose of the wearer and said prongs being 45 formed preferably of narrow strip spring steel, very light and very flexible.

δ and 6 are grips slightly arc-shaped and having cork or other facings supported at the upper ends on the stems 7. and 8 respec50 tively, said stems 7 and 8 being outwardly curved at their lower ends 9 and 10 and intermediate of the height thereof haying the lateral extensions 11 and 12 respectively and the slots 13 and 14, respectively through said extensions. The prong 1 at its lower 55 and inner extremity is secured to or integral with the stem 8 just above the slot 14, while the prong 2 at its lower and inner extremity is secured to or integral with the stem i just below the slot 13, therefore the two 60 sides of the respirator are slidably arranged within one another.

is a spiral spring caught to the lower ends 9 and 10 and distancing the grips 5 and 6 and at the same time drawing them 6 5 together when they are further separated.

In the use of this invention the prongs 1 and 2 are pressed toward one another from their lower ends, which extends the spring 15. The lobe ends of the said prongs are 70 then inserted in the nostrils and the grips 5 and 6 enter said nostrils, one on each side of the parting wall of the nose, the pressure on the prongs is then relaxed and the spring draws the grips 5 and 6 into contact 75 with the parting wall of the nostrils, at the same time the distance between the prongs 1 and 2 widens and the lobes 3 and 4 engage the inner Avail of the nostrils and widen the openings immediately at the base of 80 the bridge of the nose, thereby insuring the free passage for breathing and preventing the contraction of the nostrils under distressful circumstances.
