The shield orf cns membe s when Joined with h e he f r he h n e memb r s s a d a prp is a r ce s 19 in ermediate. lower g h reo sh ped to fit about th use of the wearer. The said shields prions mem 6 progress downwardly from said intermediate recessed portion and thence curve utwardly as indicated at l l to fit over the cheekbones under theeyes and then extend upwardly along out- 3 wardly curved side edges I2. The side edges I2 terminate in converging portions I3 above the eyes which join with the upper edges I4 at a relatively obtuse angle. The upper edges I4 of the respective lenses curve slightly downwardly intermediate the nasal and temporal sideof the lenses and thence curve slightly upwardly as indicated at I5 adjacent the location of the hinge member I. tively wide field of vision through the. lenses. The edges of the lenses are provided with bindings of leather or other suitable material I6- which are secured thereto by stitchingsor the like I1. The bindings I6, as shown in Fig. IV, areiin the form of strips of leather or the like folded over the edges of the shields or lensmembers This arrangement provides a rela'.-'.

"are secured within the bindings 3| and 32 as 6 to substantially a Ushaped cross-section throughout the top and sides of said shields and lens members. The binding I6 throughout the lower edges of the lenses, however, overlies only the front surface of the lenses with its lower edge following substantially the line of the lower edge of the lens. This is best shown in Fig.5. The said device is provided at the sides with side shield members I8 having a forward edge binding I9 thereon simulating the side edge binding I6 of the main shield portion 6. The forward edge 26 of the side shield members I8 are curved forwardly about an arc of curvature substantially similar to that of the outwardly curving arc of the edges I2 of the main shield or lens members 6. The said bindings I6 and I9 are hingedly connected with each other throughout the sides of the main shield portions or lenses 6 and the front of the side shield members I8 by suitable stitchings or the like 2|. It is to be understood that the binding at I9 is secured to the side shield I8 by suitable stitchings or the like 22 simulating the stitchings II. The side shield members I8 are provided with portions 23 formed of material generally similar to the main shield portions or lenses 6 or which, if desired, may be formed of opaque sheet material. The portions 23 have secured thereto by stitching or the like 23 flexible sections of leather or other suitable material 24 having rear edge portions 24' provided with bindings 25 and shaped to engage the face. The portions24 may or may not be provided with a plurality of vent openings 26. A headband 21 is connected with a flap of'flexible material 28 having'its forward end secured between the binder I 9 and.the'section' 23 by the stitchings 22 and is provided with a slotted portion 29 through which the headband is threaded as illustrated in Fig. 4. Theventilation openings 26 are providd in the side shields I8 when the portions 23 are formed of transparent material but when formed of opaque material the said vent open ings'l'are preferably omitted. Throughout theup perfedges ofthe main shieldsor lens portions 6 and the respective upper edges of the side shield portions I8 there is provided a flexible spacer member 38. The spacer member 3|] is preferably formed'of leather or other suitablefiexiblc material and isprovided along its opposed edges with suitable binding means 3| and 32. The said binding-means 3| and'32, like the adjacent binding'means I6, folds over the edges of the spacer member 30 with a U-shaped cross section. The binding means 3| and I6 throughout the upper "edges of the lenses and throughout the upper edges of theside shields are hingedly connected with each other by suitable stitchings or the like The binding means 32, aslsh own in Fig. 5, not only extends throughout the free edge of the best shown in Fig. 5.

The lower edges of the lenses 6 are provided with a pinked leather edge portion 31 secured in position by the stitchings 38 by means of which the binding I6 is simultaneously secured throughout said lower edges of the lenses. The pinked leather edge 31 is provided substantially throughout the inner surface thereof with a cushion edging 39 of any suitable resilient or flexible material such as rubber, fibrous felt or the.

like.

, Internally of the device and adjacent the hinge I there is provided a spacer pad 48 of rubber or other suitable resilient material. The pad 40 is secured to a strip of leather or the like 4| which is in turn secured adjacent its upper edge to the spacer member 38 by stitchings or the like 42 and is secured throughout its lower end by a portion thereof extending between the pinked leather edging 31 and the main lens portions. The spacer pad 48 may be secured to the leather strip 4| by suitable adhesive or the like throughout the inner contiguous surfaces 43. The said spacer pad is thereby loosely supported by the leather strip 4|, see Fig. 4, and provides a space 44 between the lenses 6 and the pad 46 into which the ends 45 of the auxiliary lens or shield members 46 may be extended. Each of the auxiliary lenses or shield members 46 are provided with spaced male clip portions 41 adapted to be connected with spaced female snap fastener portions 48 carried by the main lenses or shield portions 6.

The details of the snap fasteners are shown best in Fig. 2 with the female portion 48 having an internal flanged portion 49 adapted to secure the main lens portion 6 between the main member 48 and said flanged portion 49. The male member 41 is secured in position with the auxiliary lenses 46 by means of a washer-like member 58 and internal flange portion 5| between which the auxiliary lense or shield 46 is secured.

The auxiliary lenses 46 may be formed of any suitable transparent material, such as red filtering material for dark adaptation or for viewing tracer bullets; a green filter for use in the sun; an amber colored filter for use in haze or may be formed of Polaroid material for use in polarizing the light entering the device.

When it is desired to interchange one set of the auxiliary lenses for another set, the said auxiliary lenses are merely snapped loose by releasing the male portions 41 from the female portions 48 of the snap fasteners and by drawing the ends 45 outwardly of the space 44 between the spacer pad 40 and the main lens members 6. It is particularly pointed out that the ends 45, as shown in Fig. 4, when in position of use, are in spaced relation with each other whereby the main lens portion 6 may be swung about the hinge I to fit the face. This permits the ends 45 to slide longitudinally of the space 44 beneath the spacer pad 40 andalso permits the lenses 6 to be folded relative to each other when it is J desired to fold the parts of the device into compact relation with each other.

The headband 2'! may be of any of the known commercially used types connected by a suitable buckle or fastening device to secure the said headband about the head. The snap fasteners 47 show one convenient means of securing the auxiliary lens members 46 into position of use but it is to be understood that any other suitable mechanical means may be employed.

It is particularly pointed out that the auxiliary lens members 66 are secured internally of the main lens members for the purpose of preventing the collection of dust, dirt and the like between the lenses. Itis quite apparent that when the device is in fitted relation with the face no dirt or dust can gain access to the interior of the device and therefore will not collect between the lenses. The snap fastening means d? and 48 are so designed that the washer member EB and flange 49 will retain the auxiliary lenses in spaced relation with the main lens portions 6. The leather strips 7 of the hinge member, as shown in Fig. 4, will also function as spacer means internally of the device between the main lens portions 6 and the spacer pad 40.

The complete device is extremely light in weight and comfortable in use and when not in use may be folded so that the various parts thereof are in compact relation with each other for ease of conveyance.

From the foregoing description it will be seen that simple, efiicient and economical means and methods have been provided for accomplishing all of the objects and advantages of the invention.
