It is also possible to remove the positioning means for the lenses substantially out of the line of vision of the wearer, particularly near the nose bridge, thereby practically eliminating the disadvantages and defects above mentioned. The improved structure furthermore makes it possible to insert the lenses into the frames without danger of bending or otherwise stressing the frames or the lenses, and to clamp the lenses and the retainers therefor positively in place, without any danger of accidental displacement of the parts.

In the particular practical embodiment of my invention which is illustrated, the goggles -G comprise the symmetrically shaped lens frames 15 and 16, mounted by means of hinge H, to provide respective right and left hand members of said goggles. Secured pivotally by said hingeH to the frames 15 and 16, are the lens retainers C. Between the frames 15 and 16 and retainers C are the lenses L, all held securely in position by the fastener F. The frames 15 and 16 are preferably made of metal. or any material capable of being formed or shaped to be substantially L-shaped in cross-section,and yet provide a device relatively light in weight and highly resistant to deformation.

On the upper side of the goggles G, the frames 15, 16 have a cross-section which is substantially rectangular, as seen at 17. Passing around the ends 18 of the goggles, the angle becomes more obtuse, as viewed at points 19, in order to conform to the contour of the wearers face. Further, proceeding to the portions which seat upon the cheeks of the wearer, the angle becomes rapidly acute, see portions 20, for a purpose hereinafter appearing. tially vertical flanges 21 on the frames are curved to provide surface for,psitioni11g the goggles on the face of the wearer. The other flanges 22, having the angularities above described,provide the means for positioning the lenses L with respect to the eye E of the wearer, and also provide for increasing the wearers range of vision as described below.

As shown in Figs. 1, 4 and 9, the portions 28, of flanges 21, intended for disposition about the bridge of the wearers nose N, are curved concavely outwardly. This formation is necessary since the new hinge construction H brings the inner ends of the goggles so close together that said goggles could not otherwise be fitted properly to the nose of the wearer.

It will be clear from Figs. 1, 2, 9, and 11 that the frames 15 and 16 are curved longitudinally and also transversely from top to bottom as seen in Figs. 2 and 11, to fit the forehead and cheeks. Said transverse curvature is such that the upper portion of the frame, when the latter is worn, will be The upright substanarranged considerably forward of and overhang the lower portion of said frame. By this arrangement, when the goggles are worn, the focal center of the lenses L, instead of being in a horizontal line drawn from the center of each lens will be in a line extending upwardly at an angle to the horizontal. This, as shown in Fig. 2, would coincide with the focal center of the eye E.

The portions 20 of the frames 15, 16, particularly approaching the bridge portions 23, are, as previously described, not disposed horizontally or approximately so, butare given a decided inclination downwardly from rear to front, providing sufficient spacing for the .angement on the frame of the shoulders or lens positioning means 24:, which, together with lens retainers C, perform the retaining functions of a bezel. Said shoulders are so mounted as to eliminate interference with the wearers range of vision as much as is'possible and may comprise a member approximately L- shaped in cross-section, one leg 25 thereof being secured to the portions 17, 19, 20 in any suitable manner, as by means of solder or the like, while the other leg 26 is arranged to project away from the leg 25 on the portions 17,- 19, 20, at such an angle as to provide a ii-shaped groove 2'? of suitable size to receive the peripheral portions of the lenses L which generally have bevelled edge portions, as shown, against which the lens retainers C abut.

It will be seen from the drawings that the lenses L do not seat entirely within the \f-shaped groove 27. A surface of the lens L, so contacts with shoulder 2%, as to constitute a spring bearing for said lens.

As leg 26 approaches the br dge portions 23, its height is materially reduced in order to reduce the amount of material ohstructing the wearers vision in a-downward direction. It will be noted (Figs. 2, 9 and 11) that, by reason of the downward inclination of the portions 20 of the frames 15, 16., near the bridge portions 23, grooves of the proper depth and shape are provided between the shoulders 24 and portions 20, even though the upwardly projecting 26 are almost entirely removed at these points. lnrzeaed removal of material, of course, is preferable in order to increase the range of vision.

In order to further clear the line of vision of obstructions in the vicinity of the bridge, frames 15, 16, are brought together closer than has been possible heretofore by providing the hinge construction l-l, made up as hereinafter described. Said construction comprises a pair of spaced hinge cylinders 28 on one frame 16, and a single interme diate hinge cylinder 29 on the other frame member. Said cylinders may be formed in tegral with said frames, shown in lli 3 and 4, or may be secured to said frames in any other convenient manner as by partially forming some integral with the frames and soldering others thereto. The hinge pintle is passed through said cylinders to aline them and retain the frames 15, 16 in operative relation with respect to each other, the cylinder 29 substantially filling the space between the cylinders 28, whereby the frame members are free to swing about the pintle 3O relatively to each other with minimum necessary play.

Lens retainers C made up in a manner to present a flanged outer periphery shaped to conform to the contour of frames 15, 16 are hingedly mounted on each of said frames and serve to maintain the lenses L reinovably in place. The ends 31 of the retainers C ad- 3' acent the hinge cylinders 28, 29, are provided with a pair of spaced hinged cylinders'iji preferably integral with, and if so desired, formed from the same sheet of material from which the retainei are made. Hinged cylinders 83 for each of said retainers are secured to frames 15, 16, in an suitable manner. Cylinders 83, as seen in 1-, may be individually secured th reto, as by solder or the like. lhe hinge pin S 1 pivotally se cures the cylinders 82 and 33, together. lit will be seen that, by the hinge construction just described, the retainer C may be retated freely about pin 3%, and as appears from Fig. 3, sufficient space is thereby pro vided for the quick and easy insertion in place in the groove 2? of the lenses L without bending or straining the parts.

In Fig. 12, is shown a modified hinge construction in which all the hinge cylinders are made integral with the frames or with the lens retainers. ()n one lens frame 5%, the end metal is turned back to form the alined cylinders 55, 56 between which the cylinder 5? formed similarly on the other frame 58 is received. The metal between cylinders 55, 56 is turned back to form the hinge cylinder 59 which is mounted between the cylinders 60, 61 formed in the same 11 1311 nor on the end of lens retainer ()n the other lens frames, metal por ions on each side of cylinder 57 are turned back to provide the alined hinge cylinders 63, 6 1 for receiving the hin e cylinder 65 formed integral with and at the end of, lens retainer 66.;

Suitable hinge pintles are inserted through the alined hinge cylinders to position the parts for pivotal movement.

At the ends of the retainers G, opposite to that at which the hinges therefor are located, fastening means F for maintaining said retainers removably, yet securely positioned, on frames l5, 16 are provi ed. Said lugs include the internally threaded post (Fig. 5) suitably secured to the frame ends 18, as by soldering or riveting. A lug 36 having a perforation therein extends from the retainer C and maybe made of a separate piece secured to the retainer or may, if desired, be made integral therewith. Said retainers may swing about the hinge pins 84;, so that their flanged peripheries overlap the flanged portions 17, 19 and 20 of the frames 15, 16, whereby the l ns periphery isv like, an eye is suitably secured to the post.

35 in a suitable openingprovided therefor. In Figs. 6, 13 and 14, are shown modified constructions of the lens retaining locking means. In the modification shown in Fig. 6, a portion 43 is struck up from the vertical flange 21 to provide a prong over which is received the slotted extension a l of the lens retainerC. The usual snap fastener or hands for attaching the goggles to a helmet. or the like, may be secured through the opening thus provided. a r

In Figs. 13 and 1 1, a modified fastening means is shown in which a cylinder 45 is secured to'the flange 21, said cylinder having an opening 46 therethrough. A pin 47having a reduced intermediate portion 1-8 is rotatably positioned in said opening and held against sliding movement by the set screw .19 engaging said reducedportion. The head 50 of said pin has an eye formed therein, for the purpose of receiving a snap fastener of a band or helmet. The extension 51 of the lens retainer C has formec. therein the slot 52 through which the head 50 may be passed. Then, by giving the head a half turn, said head and the sides of the slot 52 will act to hold the retainer in locked position. V

A cushion 41 of rubber or other suitable resilient and comparatively soft material is shaped to conform to the contour of the rear face of the goggles. Said cushion may be secured to said goggles by stitching, the stitches being received through perforations (not shown) made in frames 15, 16. Said cushion may be interposed between the goggles and the face of the wearer to insure a comfortable air tight "and heat tight joint, and also to prevent the discomfort of contacting metallic surfaces and edges, and to insure a proper and comfortable fit to the contour of the face of a wearer, especially on the bridge of the nose and to the cheek portions thereabout. Cushion ll is thickened and widened at the bridge portion 4-2 hereof, preferably as shown in Figs. 7 and 8.

The one operation of molding the rubber cushion with a flat surface 53 for contacting the vertical flange 21 and with the thickened portions 42 avoids the operation of bulging the metal frame at the bridge portions.

If desired, suitable ventilating means 43* of the Venturi type inducing air circulation in the interior of the goggles and through passages or holes made in the walls of said goggles, may be provided.

It will be seen that there has been provided goggles wherein the obstruction to vision, particularly at and near the bridge of the nose, have been removed to a great degree, that the improved construction provides a positive and secure lug for the lens retainers, and a means for fitting the various wearers, and that the lenses may be quickly and easily inserted thereinto and removed therefrom without undue stressing of the arts.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
