To all whom it may concern:

' Be it known that I, DANA D. BARNUM, a

of attachment to the band E. The cup is citizen of the United States, residing at Worcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in ,Respirators, of which the following is a specification, accompanied by drawings forming a part of the same, in which- Figure 1 represents a human head show-' ing my improved respirator applied to the Fig. 2 is a rear view of my improved respirator, and Fig. 3 is a central vertical sectional view of the same.

Similar reference letters and figures refer to similar parts in the different views.

My present invention relates to a respirator or device for inclosing the nose and mouth, and having means for forcing air to the interior whereby a constant supply of fresh air is supplied for breathing.

My present invention is designed for the use of miners, gas men, and others required to work in impure air or noxious vapors i and it enables a constant supply of fresh air to be provided for breathing purposes and at a uniform pressure which is automatically controlled, and I accomplish this result by'means of the apparatus hereinafter described and illustrated in the accompanying I drawings; the novel features of my invention being pointed out in the annexed claims. v Referring to the accompanying drawings A denotes a cup for the nose and mouth,

preferably made of flexible and semi-elastic material, such for example, as rubber, and of sufiicient diameter and depth to receive the chin and nose of the wearer and 40 inclosing the mouth and nostrils, with the edge B of the cup pressing against the face. The cup is provided with a notch C to receive the nose, and on the opposite and lower side the cup has an interior projection D adapted to press against the under side of the chin and within the angle of the jaw bone, said projection fitting the angular space included within the sides of the jaw bone, and thereby holding the cup from movement. The cup is drawn against the face by any suitable means of attachment to the head of the wearer, preferably by means of an elastic band E, E, attached to the sides of the cup and passing around the back of the head, and an elastic band F Specificationbf Letters Patent;

Application filed February 26, 1904. Serial No. 195,399.

attached to the upper side of the cup and passing over the top of the head to a'point thereby drawn closely against the face. The edge B should be formed of some elas tic material and is preferably chamfered,

as shown at G, Fig. 3, to enable the edge to qualities of the face; but in case the cup is made of rigid or unyielding material, it should be provided with a yielding or elastic edge to accomplish the purpose named.

From one side of the cupand communicating with the interior is a pi e -H tothe end of which may be attached a ose I leading to a pump or other source of air supply, not shown, by which air is forced into the interior of the cup A. It is desirable to supply a regular and constant flow of air to the cup which is inhaled and exhaled by the wearer, and as the pressure of air increases in the cup due to its constant supply from the pump, the pressure of the edge B against the face is overcome anda portion of the air contained in the cup escapes. In this way the air is kept pure within the cup as the exhaled air from the lungs of the wearer escapes between the edge of the cup and the face, and its place is supplied by fresh air from the pump. I thus provide my respirator with a valvular margin which will yield under suflicient pressure and allow the air within the 'cup to escape and will immediately close when the pressure is relieved. I therefore obviate entirely the necessity-ffor the use of a more or less complicated outlet valve. I have shown this valvular margin constructed of rubber or an elastic material, but I do not confine myself to such form of construction v as any margin consisting of a yielding edge would come within my invention.

The amount ,of air pressure maintained within the cup A can be regulated sufliciently for all practical purposes by increasingor diminishing the pressure of the edge B against the face which may be conveniently done by varying the ten'sion of the bands E and F and to allow the tension matically regulate the pressure of air supplied to the wearer, but I also effect the desired change in the air s'ufliciently to prevent. its becoming too impure to be breathed.

My improved respirator is extremely simple and inexpensive and contains no movable parts, such as valves and the like which are liable to get out of order, and it can'be quickly applied to or removed from the face.

'lhe notch C inclosing the nose securely holds the cup from being rotated on the face and the projection D adapted to enter the hollow or depression behindthe jaw bone not only serves a similar purpose but it also prevents the lower edge of the cup from being pulled forward which might remove it from the face or destroy the close contact between the elastic edge B and the surface of the face, thereby allowing an undue escape of air from the cup. I

YVhat I claim as my invention and desire to secure by Letters-Patent is '1. A respirator, comprising a cup made of air tight material, means for attaching said cup to the head of the wearer, means for conducting air into said cup, with the edge of said cup in contact with the face of the wearer sufficiently yielding to lift as the breath is exhaled and sufficiently elastic to close as the pressure within said cup decreases.

2. A respirator, comprising a cup made of airtight material, means for conducting air into said cup, means for attaching said cup to the head of the wearer with the edge in contact with the face, said edge sufficiently beveled to be the first to yield to increase of pressure within said cup and constructed of sufficiently elastic material to close as the pressure within said cup de-- contact with the face, and a nonyielding projection with said yielding edge arranged to engage the angle within the jaw bone of the wearer, thereby preventing forward or lateral displacementof said yielding edge.

Dated this 15th day of February 1904.
