4 Claims. (01.128-141) (Granted under the act ofMal'ch a, 1883; as

amended April 30, 1928; 370 O. G. 757) The present invention relates generally to im-. provements in face masks and more particularly to fac'eprotecting masks for aviators. The present invention is a division of my copending application Serial No. 614,985, filed June 2, 1932, wherein I have disclosed a novel face protecting and protect the face from the elements while flying at high altitudes. I

' An object of the present invention is to provide in a mask of this character means for supplying gas to the-wearer which is so constructed and arranged that the gases upon entering the mask are deflected laterally and distributed more generally throughout the entire mask. In so doing direct contact of the entering gases with the face of the wearer is substantially prevented, providing for greatercomfort and .ease in breathing to the wearer.

efiected adjacent the discharge ends thereof and a more rapid exhausting of the exhaled gases from the interior of the mask will therefore be efiected.

fleretofore in face masks of this general character considerable difficulty has-been experienced in preventing the fogging of the goggles worn: by the aviator by reason of the fact that the exhaled or other gases in exhausting through the eye openings of the face mask would be con-.

densed on striking the relatively cold surfaces of g the lenses of the goggles and thus impair to a great extent the visibility aflorded the wearer.

A further object of the present invention,

therefore, isto provide in a mask of this character an arrangement whereby the exhaled gases are prevented from reaching and exhausting" through the eye openings, which is accomplished by confining the exhaled gases in the area generally surrounding the discharge outlets of the mask.

The present invention also has for an object the providing of a face mask which shall be of warm and durablematerial and which shall contribute to the maximum comfort of the To this end the helmet formed ofpliable leather with an inner lining of warm soft wearer.

-more partlcularlyto the drawings,-

wherein corresponding parts are indicated by like numerals'throughout the various views therej of, the mask in the preferredembodiment of my invention herein illustrated comprises generally a facebody portion ll, a nose portion II, throat portion l2 and chin portion l3, the-edges of the respective portions being adapted to be sewed together by means of turrier stitches with the corresponding edges of each portion. matched together in the manner designated in Figs. '7 to 10 inclusiv'ely by means of the referenceletters A to H, thus forming a unitary structure. The face body portion- Ill isformed with spaceddarts l4 and ii at its upperedgegas shown in Fig. 7, which are adapted to be stitched together and thereafter reinforced by" suitable reinforcing 5 strips [6, which may be sewed to the face portion I0, as shown in Fig.1. In a similar manner the adjacent edges of the face portion ll 1 and chin portion l3 and throat portion.- llnre I providedwith reinforcing strips l1 and It, as

shown in Figs-l and 2." Goggle openings 2'! are also formed inthe face body portion l0. The

face mask is'laminated, is, it is'formed' of an outer layer is of soft pliable leather and'aninner-lining 20 of warni soft material such as chamois. As will be noted by referring,to Fig. 2, the'nose portion. ll-is provided with apertures 22' and 23; respectively, within which are adaptedtobe re-I ceived the inlet tube 24 and exhaust tube 25 7 respectively. The exhaust tube 25 is of'suflcient length to extend through an opening zs' i-ovided in the lower portion 21 of the face body portion.

A. cup-shaped disk 28 of resilient material, such -as rubberorthelike,ismmmtedattheinner end of said exhaust tube, which is'adapted to conform to and closely contact with the lips of the wearer. I

The inlet tube 24 is closed at its inner end, as shown at 29, and is provided with a laterally extending opening 30 for discharging oxygen into the nose portion of the mask. It will be noted by referring to Fig. 2 that the lower portion to retain the inlet tube properly positioned.

As will be noted by referring to Fig. 2, a padded roll of chamois 32 is disposed on the inside of the mask adapted for making intimate contact with that portion of the wearer's face generally surrounding the nose and mouth so that the entering gases are confined in the areas designated by letters A and B. In so doing the exhaled or entering gases are prevented from reaching and exhausting through the eye openings 2| and fogging of the goggles will therefore be substantially prevented.

In order to fasten the mask in position and maintain the same in close contact with the face, the. sides of the face body portion are provided with a plurality of bands 33 of elastic material having the usual adjusting devices 34 for lengthening or shortening the bands. These bands also serve the purpose of maintaining the padded roll 32 in intimatecontact with the face of the wearer to prevent leakage of air from areas A and B into the areas generally surrounding the eye openings. The portion 35 intermediate of the eye openings 2| is slit and is provided with a tab 36 having a female glove button fastener 31 secured at its free end adapted to cooperate withthe male fastener 38 fastened on the upper face body portion. This arrangement permits the wearer to readily put on or remove his goggles without requiring removal of the face mask in so doing.

Figs. 3 to 5 inclusive illustrate a modification of the invention illustrated in Figs. 1 and 2. In this instance the eye openings 2| are provided with a padded section generally indicated by the numeral 39, which completely surrounds the eye opening, said section being so arranged as to make intimate contact with the face of the wearer about the eyes, as is indicated in Fig. 5. In so doing the exhaled or entering gases are prevented from reaching and exhausting through the eye openings to fog the goggles. The air inlet tube 24' in this modification is provided at its inner end with a plurality of flexible rubber. disks Ill and 4| cemented together at their peripheral edges to form a chamber 42 'for receiving gases. The disk It, as will be noted by referring-to Fig. 5, is provided with a plurality of openings 43, through which the entering gases are discharged laterally into the face mask.

In this modification the exhaust tubes 25' for exhausting the exhaled air from the interior of the mask are laterally disposed on the face body portion ll of the mask. As will be noted by referring to Fig. 4,. openings 14 are provided on the face portion of the mask adjacent the nose portion ll within which the inner ends of the exhaust tubes 25' are received, the outer portion of the exhaust tube beingsecured to the face body portion by means of retaining strips 45 of durable material such as leather. The outer ends of the exhaust tube 25' are extended substantially to the peripheral edges of the face body portion as shown in Figs. 3 and 4. By means of this arrangement air currents flowing past the companying drawings and referred to in the 2 above description as the preferred embodiment, is the most eiilcient and practical; yet realizing that the conditions concurrent with the adoption of my mask will necessarily vary, I desire to emphasize the fact that various minor changes 2 in'details of construction, proportion and arrangement of parts may be 'restorted to when a required without sacrificing'any of the advantages of my invention, as defined in the appended claims.
