eoaenn Application led November 5, 1926. Serial No.' 146,815.

My invention relates to goggles and particularly to the construction of the cushions which are necessary as a art of the goggles, for providing a seal an padding etween the gog le frame and the wearers face.

Gogg es are'an essential part of the equipment of lall those who are engaged inhigh My invention provides goggles of a particularly advantageous type. of construction for the use of aviators, automobilists, etc. for providing thenecessary protection against dust and flying small objects, as well as'against the wind stream caused by rapid motion.

Goggles of various types have customarily been part of' aviators and automobilists equipment/in the, past, but the advent of extremely high speedsof transportation such as those provided by the newer patterns of aeroplane's, traveling at speeds much in excess of 150 miles an hour, has shown the previous models of goggles to be inadequate, in that they do not properly seal the space behind the eye-lens from the wind stream, nor do they under all conditions protect the wearer from injury, but may themselves be a source of injury. Y

My invention provides a goggle construction embodying a sponge rubber cushion having a channeled holding means, which is adapted to provide means for firm attachment of the cushion to the go gle frame, by an attachment which is rea ily removable for change, and to protectthe wearers face against contact with the goggle frame when a sidewise pressure is exerted upon the goggle.

In my'copending application, Serial No. 747 ,168, is disclosed a goggle construction having a lens, a lens frame, a nose-place, and

a sponge rubber cushion. The. cushion, as

disclosed, has different thicknesses and different cross sectional areas at different portions. of its circumference. It haslikewise an integral sewing lip by which it may be attached to the frame of the goggle by a removable stitching. The cushion, as disclosed inthe co-pending application, is thus adapted to be adjusted inrits position to bring the point of maximum cross section into the deeper hollows on the Wcarers face and thereby provide a much better seal.

against air currents than is made by any other structures of the prior art. The construction, disclosed in the co-pending application, is entirely satisfactory for general a-utonioblle service and for most aeroplane servlce. However, at the extremely hi h speeds obtalned by aeroplanes recently gesigned, speeds rangingI above 150 `miles an hour for instance, some diiiiculty has been experienced with the construction there disclosed. It is found that if the aviator turns his head sidewise, a strong pressure is exerted on. the goggle which tends to displace it sldewise. This pressure at the very high speeds may be sutlicient to produce va. rolling effect vof the cushion and may displace it sidewise from under the edge of the goggle frame. Upon return of the aviators head to the forwardly facing position, and the resumption of pressure in the original, normal, direction from the wind stream, it sometimes happens `that the goggle frame does not .promptly return to its original position over ,the cushlon but remains displaced sidewi'se.

The wind pressure may then be suiiicient to drive the goggle frame downward beside the cushion and bring the edge of the frame into contact withvthe wearers skin, with the cushion displaced to one side and therefore furnishing insufficient protection, leven though it still makes a tight seal against the admission of air underneath the goggle.

My invention provides means for avoiding this difficulty. I provide a cushion having a channel portion integral therewith, which is adapted to hold the cushion to the goggle frame. This may be used to provide a wedging eifect somewhat similar to the principle V`involved in clincher tires, or it may, y being made in slightly different form, be used in a 'manner similar to that of the cushion in the co-pending application, and sewed to the goggle frame.

Other objects and structural details ofv my invention will be apparent from the following description when read in connection with the accompanying drawing, wherein:

Fig. 1 is an inside elevation of a pair of goggles, having attached thereto cushions constructedl in accordance with my invention; i

Fig. 2 is a plan view of the same embodiment showing also a sectional view of one of the cushions, goggle frame and lens;

Fig. 3 is a View of the same embodiment of -the cushion of my invent-ion showing the other modifications may be made as are.

found desirable. The connecting bridgepiece 3 may desirably be made adjustable to accommodate the different pupillary distances of different wearers.

Cushions 5 are provided and attached to the frame 1. The cushions 5 may be formed of sponge rubber in ring shape, as shown in Fig. 3, and may be of different sectional area at different points in the circumference as indicated.` The cushions are provided with y. two sewing lips 6 and 7 vas shown in detail in Figs. 2, 3 and 4, which are adapted to be positioned on either side o f, and surround-` ing the sewing edge of the frame 1.

In the assembling of the goggle, the various elements may be put together at the factory with the exception of the cushions. The proper position of the cushions may then be determined by the wearer to whom they are. supplied, and they may then be attached in that position to the goggle frame by means of the stitching 8. 'lhis may de sirabl be a stout thread and may be inserte by the wearer, himself, or under his direction, by means of a usual needle. Care is to be taken that the edge of the goggle frame ts well down to the bottom of the groove between the sewing lip 6 and 7 in order that the maximum width of margin may be obtained between the perforations through which the thread passes and the edge of the cushion sewing lip.

In the preceding description, I have disclosed a cushion construction having double lips which are adapted to be sewed to the frame of the goggles, in order to hold the cushion in place. I have found that when the cushions are attached in this way, that they are firmly and satisfactorily held. It 1s, however, not necessary that the cushion be held in place by a stitching through the respective lips and the frame, but they may be held in place by otherconvenient means. For instance, it is readily possible to provide a thicker lip, formed in a shape which is adapted to interlock with a stamped crevice in the frame, so that the cushions are held in place without the necessity of stitching. Likewise it is readily possible to make the lip slightly longerand hold it in place by.

clamping means on the inside and outside of the goggle frame. Alternatively it may be convenient to form the lip of a semi-hard rubber, which may be adapted to butt-on over a series of small rivets, or may be held in place by other convenient locking means.

j Likewise it may be preferred to mold the cushion with inserts of a harder material which may be adapted to interlock with the frame member of the goggles.

By these constructions, it will be seem that no matter hovv much the goggle frame is displaced sidewise, and the cushion rolled from under the edge, it will not be possible `for the material forming the sharp edge of the goggle frame to be bared so that it can malte direct contact with the wearers skin with the possibility of cutting the skin because of the pressure producedby the wind.

By these constructions of my invention, I produce a goggle, having a cushion-which provides exceptional softness of padding between the goggle frame and the wearers face, which provides exceptional tightness of fit and seal against air currents and flying objects, and which provides protection against the possibility of injury of the wearers face by the edge of the frame when the goggle is displaced sidewise by wind pressure.

While I have shown butl two embodiments of my invention in the accompanying decription, it is capable of various modifications therefrom without departing from the spirit thereof, and it is desired therefore that only such limitations shall be imposed thereon as are required by the prior art or indicated in the appended claims.

I claim as my invention:

1. 'A gog le comprising a 1 ns frame', an annular cus ion, the radial cross-section of which is a closed li re free from reentrant portions and forming a body, a pair of relatively thin, flexible extensions projecting from one face thereof, said extensions being substantially parallel and continuous, and means for securing said extensions to the lens frame withA the body in the rear thereof.
