Y CORPORATION OF NNW YORK PATENT srica f GOGGLES' Application mea November 1o, 192s. serial No. 315,357.'

This application is a continuation in part of my copending application, Serial Number 17 4,133, filed March 10, 1927. While this inl vention is applicable to goggles in general, one of its principal purposes is to meet the exacting requirements of aviators goggles, particularly with regard to the cushioning of thegoggles against the face of thewearer. Where the aviator is unprotected the wind Ylvpressure against the goggles when the air ship is traveling at high speedV is so great as to require extreme care that the eyecup members 'of the goggles vdo not come into direct contact with the face lest they will cut intol the flesh. For this reasonV they areA usually protected by cushions of suitable soft material. A thi-ck annular pad of sponge rubber is commonly employed for the purpose, and it is necessary so to attach the cushion to 2@ theeyecup that the inner edge of the eyecup f These desirable objects are attai pad or cushion of suitable soft material such as sponge rubber and of the correct shape to fit the contour ofthe face, and whichV has upon the outer a-Xial face an attaching flange which is elastic and snaps over or elastically interlocks with a complementary flange on the eyecup. I have found that this attachment affords the requisite security,rand it enables the user readily and quickly lto detach, replace or shift a cushion. It subst'if r tutes ready detachability for the more permanent modes of attaching, such as stitching, which havel heretofore been believed to be necessary.

Certain additionaldetail features of my invention will appear from the particular detion. f

Fig. 12 is a fragmentary detail of the middle portion of Fig.11 showing the position of the parts on the wearer. f f As shown inv the various illustrated embodiments, the cushion with its attaching iange may be one'integral and unitary memf ber., It will be made of a suitable soft'cushioning substance such as sponge rubber.

In the form shown in Figs. 1 to 4, inclusive, the cushion is comparatively wide and flat.

being dished to conform substantially to the vcontour of the area of the face surrounding At the nasal end the cushion is relatively narL row but elsewhere it is of considerable width, the extent of which may, of course, be varied to suit the particular needs. The flat. annular cushion is of approximately oval shape and is comparatively thick at the inner edge and tapers to a thin outer edge. For attachment of the cushion to the eyecup, the cushion is provided on its outer face with an axial lip 5 upstanding about its inner periphery and this lip terminates in an outwardly turnedgflange 6, this flange being spaced from the body of the cushion, distance equal substantially to the thickness of the metal of the eyecup. This lip and flange, therefore, serve as an undercut axial extension on the outer face of the cushion and immediatelyl surrounding the eye opening. The inner end of the eyecup is provided with an inturned flange 7 and the parts are so proportioned in size that the flanges 6 and 7 coincide or overlap when the cushion and eyecup are in their proper coaxial relation. To attach the cushion to the eyecup the lip 5 is deformed so as to permit of the insertion of the flange 6 through the flanged end of the eyecup, Vwhereupon the flange of the cushion is released and allowed to resume its normal shape. IVhile the'material of the cushion is suificiently flexible to permit of the insertion of the flange 6 past the flange 7, it also has sulcient rigidity to hold the cushion locked to the eyecup with the requisite security. The flange 7 provides a rather wide bearing surface for the cushion against the end of the eyecup and this surface surrounds the eye opening in such relation thereto as to avoid any tendency of the parts to become detached as lateral pressure is applied to the goggles. The width ofthe inner face of the cushion assures that there will be no rolling tendency of the cushion with respect to the eyecup. The width of the undercut formed by the overhanging flange 6 is just sullicient to receive the flange 7 without any unnecessary axial play between the parts. These features all make for security of attachment while they permit ready removability and replacement of a cushion.

In order to protect the nose of the wearer against injury by the protuberances which commonly result from the swivel connection between the bridge and the eyecups, I may provide a protecting flap 8. VThis flap is preferably molded integral with the cushion and upstands on its outer face between the flanged lip 5 and the outer periphery of the cushion at its nasal end. As shown in Fig. 1. 1t covers up the joint between the bridge and the eyecups and thus protects the nose.

is desirable with such a cushion that it be capable of adjustment rotatively within the eyecup to adapt it for wear by dierent persons. Upon the outer axial face, this cushion is provided with an axially extending` lip 10 terminating in an outwardly turned llange 11 and this flange ts over the inwardly extending flange 7 on the eyecup 4. This flange 7 affords a sufficiently wide bearing surface against. the outer face of the body of the cushion around the outside of the lip 10 to prevent any accidental separation of the parts in use. I will ordinarily form the lip 10 on the outer face of the ring substantially midway between the inner and outer peripheries. Not only is this mode of attachment sumciently secure for all purposes, but it permits the ring to be easily rotatively adjusted to fit it to the contour of the face ofthe wearer and also to be easily detached and applied.

The construction shown in Figs. 6 and 7 differs from those above described in that the flanges are reversed, that is, the flange on the eyecup is outwardly turned and that on the cushion is inwardly turned. The cushions 1 and 2 are ring-shaped and approximately round in cross section, substantially corresponding in this respect to the construction shown in Fig. 5. The cushion 1 is applied to the eyecup 3 and the cushion 2 is applied to the eyecup 4. The eyecups have their inner ends provided with an outward flange 12, and the cushions have on their outer axial face an undercut formed by the inwardly turned lip or flange 13. The elasticity of the cushion permits it to be expanded in diameter so that the lip 13 will snap over the flange 12 and thus secure the parts together while permitting of ready detachment. In the form of cushion shown in these figures the undercut is disposed somewhat outside of the center line of the top surface toward the outer periphery. It may also desirably be formed on the top more toward the inner periphery, as shown in the case of the cushion 1a of Fig. 8. In this latter iigure, the attaching lip 13 is Vdirected inwardly from substantially the center line of the top surface. N hen molded in this way the elastic lip obtains a more substantial hold upon the goggle frame when it is stretched or snapped over the outwardly turned flange of lhe eyecup.

In the construction illustrated in Figure 9 the cushion 9a corresponds in general to the cushion of Figure 5 in that it is round in cross section and has an outwardly flanged lip 11a engaging over the inturned flange' 7 a of the eyecup 4a. Additionally, however, this cushion has a second lip 14 on its outer face which clamps between the usual hinged lens cover and the eyecup. This lip 14 serves as a gasket to prevent air seepage in the eyecup and a-lso manifestly the clamping of this lip between the metal parts makes the attachment of the cushion to the eyecup more positive in character.

VIn the construction shown in Figs. 10, 11 and 12, a somewhat different way is provided for protecting the nose. Instead of having the flap 8, the cushions 16 and 17l are 'provided at their inner or nasal ends with extensions 16 and 17 which are of aV length to overlap, as shown, and of a width to protect Vthe nose from the entire bridge 18. The extensions will be thin and will ordinarily be formed as continuaticns of the o'eneral plane of the inner face of the cushions. rlhey will yield to accommodate the nose of the wearer,

as indicated in Fig. 12, and will be of such' length as still to overlap when thus pushed outwardly by the nose. v

In the description and in vthe appended claims I referto the cushion snapping over or upon ,the eyecup, intending such expression to comprehend the engagement of a lip elastically with the eyecup whether the cushion flange be inturned and requiring a stretching to apply it over the interlocking part on the eyecup, or be turned outwardly and require a contraction of the lip to apply the Y flange to the eyecup.

While I have shown several embodiments of the device of my invention in the accompanying description, it is capable of'various other modifications therefrom without departing from the spirit ofmy invention and it is desired, therefore, that only such limitations sliall be imposed thereon as are required by the prior art or indicated by the appendedV claims.
