7 Claims.

This invention relates to a goggle and more particularly to the framing device for the lens; and has for one of its objects to provide a simple and eiective means for providing free and abundant ventilation to the inner surface of the lens while at the same time excluding Idust and other such foreign matter.

Another object of the invention is to provide a simple means for alfording flow of air in somewhat of a bailed manner.

Another object of the invention is to provide in the Ventilating means a cushion that some resilience may be had for assisting in preventing breakage of the lens when subjected to pressure or shock.

With these and other objects in view the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawing:

Fig. l is a sectional view through the eye cup of the goggle showing the lens and cap mounted in place;

Fig. 2 is a section on line 2-2 of Fig. l;

Fig. 3 is an exploded view of the various parts illustrated in Fig. 1;

Fig. 4 is a perspective fragmental view of a modication showing a portion of the eye cup and the spacer member;

Fig. 5 is a view similar to Fig. 4 of a different modied form of cup and spacer;

Fig. 6 is a section on line 6-6 of Fig. 5;

Fig. '7 is a fragmental persepective View of the cup alone as shown in Fig. 6;

Fig. 8 is a perspective view of structure similar to that shown in Fig. 5, but illustrating a still different spacer member positioned on the cup; and

Figs. 9, 9a and 9b are a series of fragmental perspective views illustrating the two parts separated and also these parts in assembled relation.

In various occupations, operators are subjected to heat or the hazards of flying particles, making it desirable that the eyes should be carefully shielded, as by goggles. In such goggles it is also desirable that there be good ventilation so that the lens will not steam up or cause any or, scuring of vision due to moisture condensation. It is also desirable that the ventilation be near the inner surface of the lens and be abundantly provided. In order to accomplish this result in a very simple and effective manner, I have arranged a spacer member which will engage the end of the eye cup to be positioned between the lens and the eye cup, and provided the same with CII a novel formation and in some instances arranged for retaining this spacer member in position by the formation of the end of the eye cup such, for instance, as grooving or providing a projecting guide. The spacer is formed of metal and either cut or bent into desired shape such` as by coiling or other means to provide a spacing for the Ylateral flow of air; and the following is a more detailed description of the present embodiment of this invention, illustrating the preferred means iby which these advantageous results may be accomplished:

With reference to the drawing, IU designates an eye cup usually formed of some plastic, molded material. although metal may be utilize-d, provided with a Ventilating opening Il, shielded by some perforated member l2. The outer surface of this cup is threaded as at I3 and a cap I4 provided with a ange i5 having threads i6 in engagement with the threads I3 of the cup. The lens Il is engaged by the inwardly-extending portion l 3 of the cap so as to force the lens toward the edge of the cup as the cap is screwed in place.

The flange of the cap is provided with a series of openings spaced peripherally about the same as at lil for the passage of air therethrough. The spacing member is located to engage the undersurface 20 of the lens l1 and to engage the upper edge 2! of the cup. This spacing element may take several different forms. In Fig. 3 I have illustrated this spacing member 24 as formed from a helical coil of wire, the spaces between the helical coil providing lateral passages for the flow of air through them. In some cases this helical coil member may be set into a recess 25 in the edge 2l of the cup as illustrated in Fig. 4, while in other instances it may rest upon the edge 2l of the cup as illustrated in Figs. 1 and By this arrangement the air as it passes through openings I9 may pass through the convolutions of the coil directly along the inner surface of the lens for ventilation of the same. The inclination and close spacing of the coils of wire serve to baille the air entering the cup.

In other cases I may provide the spacer in the form of an inverted U, as illustrated at 26 in Fig. 5. In this case, openings 21 will lbe provided through both walls of the U in staggered relation so that air as it passes will be baffled rather than having direct flow through the spacing member.

In order that this spacer 2@ may be retained in place centrally of the cup Il), a rib 28 is raised particles which on the edge 2|' of substantially a width to iit n between the inverted channel of the spacer 26. In Fig. 8 this inverted channel instead of being bent on the arc as illustrated in Fig. 5 is designated generally 30 and is provided with right angular bends 3l and with projections 32 cut and raised from the stock of the bridging wall of this inverted channel. These raised portions serve to provide a cushion orY some resiliency for engagement with the edge of the lens such as provided by the coil wire above mentioned.

In Fig. 9 the edge 2l at 33 and a channel 34 having bottom wall 35 and side walls 36 notched as at 31 may be set into this recess 33 as illustrated to provide a different form of spacing member from that heretofore mentioned. The notches 31 will be in staggered relation in the walls 3S so that no direct passage of air through the spacing member will be provided.

By providing the cup I may easily and quickly lock the spacing member so that there may be an adequate annular space 38 provided between the cap and the spacing member for annular circulation of air supplied through the openings I9. By the arrangement of the openings in staggered relation, and by reason of the formation of the helical wire in that form of the device, any foreign may be ilying would be prevented from entering the cup to be a hazard.

I claim:
