Cloth 26 serves other useful purposes in addition to `diffusing the ow of air into the interior of the goggle and thus minimizing the wearers consciousness of the incoming air. It also acts asa filter for dustor any other foreign material which it may be desirable to exclude from the wearers eyes. Furthermore, if the goggle is to be used for dark adaptation purposes, in which case lens 2i) will comprise dark red material, y

cloth 26 should be of such color and texture as to exclude all undesired light. It should be pointed out, however, that the invention is in no way limited to the use of diffusing means or to the particular mounting means therefor shown in the land the interior portion of the goggle, but not to nose chamber I5 and the wearers nose. The means for accomplishing the latter result are shown particularly in Figs. 1, 2 and 4. Shield 35, preferably of the same material as the remainder of frame Ill, is mounted on the front thereof as by means of a suitable cement, and forms with the front of frame I an additional chamber 36. Shield 35 is provided with a plurality of internal nubs 33 adapted to maintain it in spaced relation with frame I0. A plurality of apertures lil in the upper part of nose-engaging portion I6 provide communication between the interior of the goggle and air chamber 36. Communication between chamber 36-and nose chamber I 5 may be provided by means of any suitable one-way or flutter valve, and an example of a satisfactory valve device is shown particularly in Figs. 1 and 2.

Frame I0 is molded initially with valve-mounting means comprising a plurality of ribs 42 interspersed with apertures 44 and connecting with a central rim 45. Valve stem 46 of valve 55 is adapted to engage in rim 45 and is provided with an enlarged head 48 which will prevent its withdrawal therefrom. Valve 50 is preferably made of a relatively thin, flexible material such as rubber and should be sufficiently light and flexible to offer minimum resistance to the passage of air through apertures 44 during inhalation by the wearer of the goggle, but should at the same time be sufficiently firm to seal said apertures at all other times.

Itwill now be apparentthat each time the wearer of the goggle of the invention inhales through his nose, he draws air through diffusing element 26 into the interior of the goggle, and thence through apertures 40 into chamber 36, whence it passes by way of apertures 44 and valve 50 into nose chamber I5 and the nose of the wearer. It will also be apparent that the oneway action of valve 50, together with the sealed t of nose chamber I to the face of the wearer, serves to prevent exhaled air from returning to the interior of the goggle and thus insures maintenance of the desired fog-free condition of lens 2U.'

At .the lower part of nose chamber I5, there is provided a further valve assembly similar in function to valve 5I) for purposes of exhalation. Any convenient one-way valve may be used, and the illustrated example comprises ribs 52, apertures 54, central rim 55, valve stem 56 provided with enlarged head 58, and valve 6I) corresponding in construction and action to valve 5D. There will preferably be provided also a protecting rim 62 for valvel which alsoacts to deiiect exhaled air and prevent it from striking the outer surface of lens 20. If the goggle is designed for use at extremely low temperatures, rim 62 may be substantially increased in length in order to lessen the possibility of congealing the moisture in the exhaled air, which might tend to prevent valve from sealing apertures 54 properly during inhalation. It will be noted, however, that valve 60 and its mounting means are necessary only to permit the wearer of the goggle to exhale through his nose, and may be dispensed within a simpler embodiment ofthe invention. In such case, the lower part of nose chamber I5 will be permanently sealed and the wearer of the goggle will have to exhale at all times through his mouth.

Any suitable means may be employed for mounting the goggle of the invention on the head of the wearer, but the arrangement shown in Figs. l and 4 has been found particularly satisfactory. Straps 64 engage in slots 65, preferably T-shaped and lined with suitable grommets 66, in lens 2B, and are provided at their inner ends With a suitable lug or bead 68 adapted to prevent withdrawal through slots 65. If desired, a slotted washer element 69 may be used to insure sealing of slots $5 against the passage of air therethrough during inhalation. Additional support may be provided if desired by means of ears 'Ill at the outer ends of frame, Ii) provided with transverse slots 72 through which straps B4 pass in encircling the head of the wearer. The invention is in no way limited to this mounting arrangement, however, and many satisfactory variations therein will be readily apparent to those skilled in the art.

Since certain changes may be made in the above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intendedthat all 5 matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all the generic and specific features of the invention herein described,
