GOGGLE S Fil ed Jan. 15, 1930 A'i'ToR'NEY Patented May 28, 1935 GOGGLES V I Emil B. Meyrowitz, New York, N. Y., assignor to E. B. Meyrowitz, Inc., a corporation of New York Application January 15, i930, Serial No. 420,830

7 Claims.

This invention relates especially to goggles for use where high wind pressure is encountered, as is the case, for example, with aviators. A cushion is ordinarilyprovided about the rear edge of the eyecups of such goggles to protect the face of the wearer, and some means are also provided to ventilate the eyecups so the lenses. i

While the cushions should of course be held securely to the eyecups, it is desirable that they be easily and quickly replaceable and thattheir mode of detachment in no wise interfere with the ventilation and with other functions of the eyecup. In accordance with my invention, I lock the lip of the cushion within the rim of the eyecup by ineansof an inner reinforcing band which is prefas to prevent fogging of erably secured to the inner face otthe lipand by reason of "the relative configuration of the eyecup and rim positively locks the lip in the eyecup so long as the parts are intheir normal or usable shape. Either the bandv or the eyecup, however, are resiliently deformable so asto permit of detachment. Atthe same time theband serves as a deflector to direct the air entering the ventilator toward the lens and away' fromthe eye ial separation or insertion until the eyecup is l opened. For instance, theyimay both flare out-.

40 wardly away from the rear suifi'ciently to afford of the wearer.. A p H In one form, for example; in whichthe eyecup is an endlessband and the lensisheld' in place i In the case of an eyecup whichopens at the temple end and so is expanded to receive the lens and thecushion lipythe rim of the eyecup and :the reinforcing band may be shaped so as mutualfly to overhang circumferentially and prevent ax- ;a positive lock. l r

" The security of this interlock may 'be enhanced by placing-the loop or eye member to which the head band is attached, on the reinforcing band and having it protrude through the cushion lip and through an opening in the temple end of the eyecup. This may be done in the adapted to cooperate with the usual ventilating devices in which the inlet and outlet ventilation openings are in opposite sides of the eyecup. The inlet opening is usually in the bottom wall of the eyecup and the general width of the lip and reinforcing band at this point is such that they would cover the inlet opening. The lip, however,

is cut away opposite the inlet opening so as to leavethe band opposing the opening and spaced from it by the thickness of the lip. The inooming air, therefore, strikes the band and is deflected toward the lens. This deflecting action may be improved by bending the deflecting por tion of the band slightly inwardly away from the cushion lip, which may readily be done by slitting the band inwardly a short distance from its edge and turning in the slitted portion. At the outlet ventilating opening, the lip and the reinforcing band are made sufficiently narrow to stop short'ol this opening and leave it entirely uncovered. It will be noted that this ventilating feature of the structure does not interfere at all with the interlocking feature.

Other detailed respects in which my invention improves upon prior devices of this sort willappear from the following description of certain embodiments of my invention which I have "selected for the purpose of illustration; i

section of the same on single goggle memstruction in that the eyecup is not split at the temple end but is an endless band. The eyecup I is an endless metallic band of oval outline with the lens 2 resting upon suitable supports 3 on the inner face of the eyecup. A lens cover ring 4 is hinged at the inner end of the eyecup and telescopes over the eyecup, having a narrow flange which overlies the edge of the lens and secures it in the eyecup. The usual hinged clasp 5 on the outer or temple end of the cover ring engages over the head band loop in the usualway to hold the cover closed.

Fitting'within the eyecupw from its rear is the lip 6a of the cushion member 6. This lip 6a is a circumferential axially extending lip of a size and shape to fit snugly within the eyecup rim. Within this lip 6a is a circumferential reinforcing resilient metallic band I which is shown as secured to the lip by stitching. a line inwardly of the central vertical axis of the reinforcing band are two opposed detent members 8. These are shown as separate members riveted to the band. They extend above the outer edge of .the lip and, in the assembled position of the parts, they engage in'recesses la formed in the wall of the eyecup. The band i is sufficiently flexible to be easily deformable. Therefore, by springing the walls of the band together toward the inner end of the elliptical ring,

these "detents may be brought together so as to release them from the recesses Ia.

' At the temple end of the elliptical band, the band is provided with an outwardly projecting .loopor eye 9 which serves for attachment of thehead band in the usual way. This loop 9 extends through aslit in the lip 6a and also through an opening in .the band I. "It, therefore, serves as a third point of attachment of the band to the eyecup. The clasp 5 closes over this loop or eye 9, as above mentioned.

To insert the cushion in the eyecup, one first inserts the eye 9 through the opening in the eyecup and then springs the wall of the band and the lip together toward the opposite end and :pushes the lip into the eyecup until the detents engage in the recess la. The lip is thus :securely locked in thereyecup. To remove the cushion, it is only necessary to reverse the op- -.eration,- first deforming the band so as to: disengage the detents 8 from the recesses la and withdrawing that end of the cushion, and lastly, withdrawing the eye member 9 from the eyecup.

To ventilate the space'back of the lens so as to 'prevent fogging, the eyecup is shown as having well' known ventilating means.- The air inlet is at the bottom of the eyecup and the outlet is at the-top. 'The inlet consists of a series of circumferentially spaced holes Hi. The flange of the cover 4 which telescopes over the eyecup has a series of holes I l which register with the holes 6 0 .:When the cover isjclosed. Air is directed toward the inlet openings by a battlemember l2 which is larch-shaped in cross section with closed ends and is-secured on the eyecup wall over the inlet outer edge for the reception of the lens.

openings and is provided along its front face with a series of openings l3. As the wearer of the goggle moves forward, the air is therefore caught by the openings l3 and is directed by the baflie into the openings I0 and H.

The lip 6a is cut away at its outer edge over the circumferential distance occupied by the inlet openings lfi so as to leave these openings uncovered on the inside of the eyecup. This appears quite clearly from Fig. i. The band 7, however, extends with its outer edge above the cut away portion of the lip and in front of the inlet openings and serves to direct the incoming air toward the lens. As shown in Fig. 4, this deflector portion of the band may be turned inwardly so as more effectively to deflect the air toward the lens, and for this purpose the band is slitted on opposite sides of the deflector portion. In the top wall of the eyecup there is formed a circumferentially extending outlet portion l4, and the flange of the cover member 4 which embraces the eyecup has a corresponding opening l5 which registers with the opening M. An arch-shaped baffle member it, provided with a longitudinal series of outlet openings may also be secured on the cover member over the openings 1 5.

v In Figs. 8 to 13, inclusive, I have shown my invention applied to a so-called open eyecup, that is, one which is split at the temple end and opens up at this joint to admit and release the lens and the cushion. The illustrated eyecup is generally of the form disclosed in my copending application Serial No. 337,559, filed February 5, 1929. The wall'l'l of the eyecup flares outwardly from its inner side and has a V-shaped bezzle Ha at its The lip 18a of the cushion I8 is similarly flared, as is the reinforcing band it, which is secured about the inner face'of the lip, as by stitching. When the eyecup is opened up, the flared lip with its that when the eyecup is closed, an opening is left for the loop 9. This appears clearly in Figs. 11, 12 and 13. A hinged latch member 20 on one end section has an opening in it sufiiciently long to receive the loop 9 and to latch over a catch 2| on the opposing end section.

As shown in Fig. 14, it is not essential to the invention that the loop 9 be on the band I 9 since the lip with its reinforcing band will be locked positively in the eyecup by the overhang due to the flare of the eyecup and enclosed members. Therefore, the loop or eye member 9a may be on one of the ends of the eyecup and serve as the catch for the latch member 20. In this case only the end which carries the latch member will be bifurcated so as to straddle the eye memberSa when the eyecup is closed.

In either case the ventilating construction of the lip and reinforcing band of the cushion will be similar to that of the cushion member of Figs. 1 to 7, inclusive. The lip Ifla will be cut out, as shown in Fig. 10, at the point where it would otherwise cover the inlet openings, and the band l9 will be slitted and turned back opposite the ventilation openings so as to form a deflector em erappears alsoclearly in Fig. .9.

The bearing for the leg of the bridge member 22 protrudes internally of the eyecup, and the lip l8a and the reinforcing band 19 are also cut away at this point to accommodate this bearing.

It is obvious that various modifications may be made in the constructions shown in the drawing and above particularly described within the principle and scope ofmy invention.
