FACE MASK Filed .July 16. 193e INVENTQR ATTQRNEYS Rohff t YTitus Patented May 25, 1937 PATENT OFFICE FACE Mask' Robert s. mus, New'aocheue, N. Y.

Application July 16,

15 Claims.

This invention relatesto a face mask and more particularly to a mask adapted to be worn in shielding relation to the nose and mouth to protect the wearer from inhaling or exhaling foreignV or infectious matter.

One object of the invention is to provide a mask which will be simple and economical of construction, and thus capable of being manufacturedand sold at a low cost.

Another object of the invention is to so form the mask that when in use it will iit closely against the face, conforming to the shape thereof, thus very effectively preventing the passage of ,foreign or infectious matter between the face and the marginal portions of the mask.

Another object of the invention is to provide the mask with improved strands, or balls, which are yfitted through pockets or hems along upper 'and lower margins of the fabric body of the mask, and which strands or bails may be very easily and quickly inserted or removed, thus permitting the strands or balls to be transferred from one mask to another, and alsa permitting the mask and strands to be thoroughly cleansed and steri- 325 lized separately. A

\ 'Another object of the invention is toprovide strands or bails which may be easily bent to conform to the contour of the portions of the wearers face alongwhich margins of the mask extend,

30 which strands or balls may alsov'ihave portions which project from the ends of the mask in such manner that they may bebent to engage back of the wearers ears and in'gripping engagement with the wearers neck below the jaw. f

35 Another object of the invention is to so bend the projecting portions of the upper strand or bail that they will engage back of the wearers ears and firmly hold the mask in' place, without allowing the portions which bear against the wearers face 40 to interfere when glasses or spectacles are worn.

Another object of the invention is to provide a mask which will be durable in construction, and

consequently economical to use.

Another object of the invention is to provide a mask which will be lquick and easy to apply and to remove, as well as comfortable to wear.

Still another object of the invention is to pro? vide a mask in which the strands or bails and the fabric parts will be interchangeable.

With these and numerous other objects in view. my invention con`sistsinv the novel features oi construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims, i

The invention is illustrated in the accompanying drawing wherein: Figure 1 is a perspective view vshowing the improved mask in use;

1936, serial No. 91,009 (ci. 12s-14s) Figure 21s a view looking at the mask with the strands, or bails,v removed;

Figure 3 is a sectional view'taken along the line 3-3 ofFlgure 2; l

Figure 4 is an end view of the mask with the strands, or balls, removed;

. Figure 5 is a sectional view taken along the line 5-5 of Figure 2;'v

Figure 6 is a perspective view of the upper strand; and 4 l Figure 'I is a perspective` view of theA lower strand. i

The mask l is formed oi fabric'and consists of a strip of gauze which is doubled intermediate its length to dispose its ends in registry with each other as shown in Figure 3 and then re- Adoubled as shown in this figure. Therefore, the single length of gauze forms a mask having a plurality of plies which will be referred to as inner and outer plies and are designated by the numerals 2 and 3 in Figures 3 and 5. The portions of the strip of gauze forming the outer plies are. of greater width than the portions forming the inner plies as is clearly shown in Figure 5 and the protruding upper and lower portions of the outer plies are folded inwardly in a rearward direction and disposedy in overlying relation to 'upper and lower marginal portions of the inner plies where they are secured bystitchng 4. Outer lines of stitching defining hems 6 serving as retaining means and through which upper and lower strands or bails are to be passed. While it has been stated that the mask has four "plies it will be obvious that this number may be varied and more or less plis provided if s'o desired. The fact that the mask may be formed of sterilized gauze produces a mask having antiseptic qualities which will protect the wearer from inhaling orexhaling foreign or infectlous matter. It is desired to have the mask gradually reduced in Width towards its ends and in order to accomplish this', portions of theinner and outer plies are folded and stitched to form pleats 1 at each end, which pleats reduce the width of the mask and cause lit to taper towards its ends as shown in Figure 2. Therefore, when the m-ask is applied to the wearers face with its upper marginal portion over the nose and`its lower marginal portion-under the chin the curvature of its upper and lower edges will cause it to t properly against the wearers face.

The upper and lower strands, or bails, 8 and's, by means of which the mask is to be held in shielding relation to the wearers face, are formed of pliable metal which-may be very easily bent without likelihood of fracture. They may be made of any soft metal, but silver or chromeplated copper are preferable, as they may be easily bent and at the same time are not subject to corrosion or rust. It should be clearly understood.

5 are passed through the folds, thus however, that for industrial purposes some other soft metal may be substituted'. Ends of the strands, or balls, are thickened, or beaded, as shown at l0 and Il, to provide knobs which permit the strands to be easily passed through the heis 8 without catching in the gauzefabric and tearing the mask. These knobs, or beads, also serve to provide the strands with blunt ends and so prevent them from digging into the wearers skin and causing discomfort when the mask is worn. The strands, or balls, as initially supplied with the mask are straight instead of being shaped as shown in 'Figures 1, 6 and 7. Therefore, when initially applying the mask, the strands or balls may be bent to conform to the contourof the wearers face, and the marginal edges of the -mask will fit closely against'the nose and cheeks,

also against the chin and jaw. The protruding end portions of the upper strand, or bail, resemble the bows of a pair of spectacles, and are formed with end hooks l2 to engage overand back of the wearers ears, but instead of extending straight from the ends of the mask, they are bent so that they are bowed or curved` longitudinally and merge into the curved or bowed upper edge portion of the mask. By so bending the upper strand, or bail, its projecting end portions will approach the ears at such an A.angle that they will notr be in the way if glasses are worn, and there will be no danger of the upper strand vor the upper marginal edge of the mask making contact with the glasses and dislodging them. The lower strand, or bail, has its projecting end portions bent to conform to the curvature of the wearers neck in such manner as to form a lx1-shaped jaw which will grip the neck on opposite sides and hold the lower portion ofthe mask iirrnly in place.

After the mask has been adjusted and applied it may `have additional adjustments made by bending the upper and lower strands until they t snugly against the portions of the face andl neck with which they come in contact, and the passage of foreign or infectious matterto or from the nose and mouth of the wearer will be prevented. It will be noted that the mask will also be worn by persons afflicted with contagious diseases communicable through respiration to prevent the discharge of such disease germs. After the mask has been removed it may be cleansed and sterilized either with or without the strands, or bells, in place, and then used over again, or the strands may be removed and the maskdiscarded', retaining the-strands tobe inserted in a new mask when desired. As masks for the prevention of the communication of disease are only used once before being sterilized'again,

it will be seen that the interchangeability of masks and strands is a most desirable feature. IIhis mask is simple in construction, capable of being easily and quickly applied or removed, very comfortable for the wearer, may be easily and cheaply wrapped in air-tight, sterile packages, may be manufactured at a. low cost and sold at a correspondingly low price, and will fit any wearer, regardless of shape of face. It will thus be seen that it has many desirable features.`

From the foregoing description of the construction of my improved apparatus, the application of the same to use will be readily understood. It will be seen that I have provided a simple, inexpensive, and eillcient means for carrying out the objects of the invention.

While I have particularly described the elements best adapted to perform the functions set Vment with a` persons neck from forth, it is obvious that various changes in form, proportionfand in the minor details of construction may be resorted to without departing from the spirit orsacricing any of the principles of the invention.
