NATHAN SCHWARTZ, OF NEW YORK, N. Y.

RESPIRATOR-MASK.

Specification of Letters Patent.

Application filed March 28, 1918. Serial No. 225,232.

To all whom it may concern."

.Be it known that I, NATHAN SoHwAaTz, a citizen of the United States, and aresldent of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Respirator-Mask, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved respirator mask more especially designed for the use of persons Working in dusty places, and arranged to protect the user against inhaling dust, noxious and poisonous fumes and gases, or infectious and contagious diseases liable to be contracted by inhaling dust containing bacteria of a pathogenic nature. Another object is to permit of conveniently and quickly attaching and holding the respirator mask in position on the face of the user or removing it therefrom whenever it is desired to do so. Another object is to insure a snug fit of the respirator inask to the face of the wearer and without hindering free inhaling and exhaling. Another object is to prevent chafing or otherwise injuring the skin of the wearer.

With'these and other objects in view, the invention consists of certain novel features of construction, as hereinafter shown and described and then specifically pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawrings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a. perspective view of the respirator mask as applied; 7

Fig. 2 is an exaggerated cross section of the same;

Fig. 3 is a rear perspective view of the same; and Fig. 4; is a plan view of a portion of the body before the binding is applied and showing the notch forming a dart.

The body 10 of the respirator mask is formed of a pluralityof superimposed pieces 11 of open mesh textile fabrics such as gauze, cheesecloth or similar soft material, the pieces being bound together along the margins by a binding 12 fastened to the pieces 11 by transverse stitches 13. The binding 12 is preferably made of strong close mesh material such as is generally used for binding purposes in garments and the like to give the desired strength to the body 10 and to prevent distortion of the open mesh pieces 11. he body 10 is approximately straight along the upper edge, and the sides are "straight in the upper portion and curved gradually into the ,approximately semicircular bottom of the body. The binding .12 contains a piece 15 of soft Wire or similar pliable material disposed approximately at the middle of the top portion of the body, and this pieceof Wire is bent so as to conform to the, shape of the nose at the bone thereof, it being understood that by bending the wire in this manner the binding and the corresponding adjacent portion of the body is shaped to conform to the shape of the nose, as will-be readily under stood by reference to Figs. 1 lar piece 18 of soft wire or similar pliable material is arranged in the binding at the bottom portion and is bent to conform to the shape of the under side of the chin of the tom edge of the mask under the chin'of the wearer.

The sides of the body 10 are provided with ear loops 20, preferably made of elas tie bands, each having one end sewed to the corresponding upper corner of the mask at the binding 12, and the otherv end sewed to the binding a distance down at the corresponding side of the mask. The ear loops 20 are adapted to be passed around the ears of the wearer so as to firmly hold the mask in position on the face of the wearer, it being understood that the ear loops 20 are sufficiently short to require stretching of the but spaced from the inner edge of the binding 12 so that the retaining flap 25 extends upwardly onto the corresponding top portion of the binding 12. A similar retaining flap 27 is arranged on .the inner side of the body at the bottom and side portions adjacent the corresponding portion of the binding 12, and this retaining flap 27 is fastened to the Patented J an. 21 1919.

and 3. Asimiwearer to insure a tight fitting of the bot- 4 cally out of contact -cient space is provided for the mouth and Q mes es onto the body ll by stitches 28 andextefnds Figs. 2

binding, as plainly indicated in and 3.

It will be noticed that by the arrangement described, the user of I the mask can readily shape the nose and chin portions thereof to correspond to the configuration of the nose and chin of the wearer with a view to insure a tight fitting of the mask on the face of the wearer at the time the loops are engaged with the ears. It will also be noticed that'by having the binding a tight joint is had between the skin of the face and the binding while the body 10 is practiwith the skin and suffinostrils to insure free inhaling and exhaling. In practice, the middle, top and bottom portions of thebody 10 are provided with darts 30 and 31 to give the proper shape to the body 10 for the nose and chin. By the arrangement described the mask assumes the shape of a bowl or cup and thus provides .a breathing chamber which permits indirect respiration.

By shaping the body 10 as described and shown in the drawings, the undesirable and.

unsightly muzzle appearance is avoided and the respirator appears with a veil effect or a mask effect.

It will be noticed. that by superimposing a number of pieces 11 of open mesh textile fabrics the user can breathe freely, and the air drawn through the meshes on inhaling is thoroughly filtered and purified, and hence only pure air enters the users system. It will further be noticed that the meshes of succeeding pieces 11 are naturally staggered whereby dust and other solid and finely divided matter is retained. The respirator mask can be washed from time to time to wash out the solidmatter and thus permit the use of the mask for a long time.

The respirator mask shown and described is simple in construction and can be cheaply manufactured and readily applied by the user.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A respirator mask having 'a body formed of a plurality of superimposed pieces of open'mesh textile fabrics, a binding for holding the pieces together, and retaining flaps secured to the inner side of the adjacent the binding and overlapping the latter in an outward direction,

2. A respirator mask having a body portion formed of a plurality of superimposed pieces of textile fabric, said body portion being provided with a transverse dart ar ranged near and beneath the upper edge thereof to impart to the mask a desired fullness for the reception of the nose, a binding at the edges of said pieces to hold them together, a piece of soft wire secured to the body-portion at the upper edge thereof and adapted to be bent into a shape for the reception of the nose, a retaining flap secured to the inner side of the body portion near its upper edge and partly overlapping the binding, and retaining elements secured to the sides of the body portion. I
