Patented Apr. 25, 1933 UNITI-:D STATES PATENT- oFFlca i' GEORGE A. BINDER, OF CHICAGO, rumors, AssIGNoR 'ro ROBERT MALCOM, or CHICAGO,

`ILLINOIS f GOGGLES My inventionrelates more particularly to V'goggles involving eye-cups adapted to more or less closely fit about the eyes of the wearer; the invention having for its object the provision of means associated with the lenses .whereby lproper circulation of air about the lens and within the lens holding end Vof the eye-cup may be obtained and the formation of condensate on the lens interior or fogging of the lens prevented. s

My invention also involvesmeans whereby the degree of air circulation may be regulated in lkeeping with the desires and needs of the wearer under Varying conditions of use.

The objects and advantages of my invention will be readily comprehended from the following detailed description of the accompanying drawing wherein:

Figure 1 is a transverse sectional elevationV and machinists when working with welding torches, abrading machines, metal chipping and the like, requiring full eye protection and therefore goggles which will conform more or less to the face and fit comparatively closely about the eyes. `Considerable Adiiiiculty and discomfort has been encountered with goggles of this character, due to lack of proper ventilation within the eye-.cups and particularly adjacent to the inner face or side of the lens, causing the lens to become fogged and vision made indistinct.

For purposes of eXem'plification, I have .disclosed my invention applied 'to agoggle eye-cup of the type especially adapted to be used by a mechanic whose eye-sight necessitates the constant wearing of eye-glassesor spectacles. Y

Therefore, the temple side of the eyefc'n" wall 1() is shown moulded or provided witii an outward off-set or spectacle arm receiving socket at 11 disposed transversely of the eyen cup W-all from outer or lens end toward the inner orrface engaging perimeter, where it terminates in a slotted ear 12 intended to receive the usual headstraps whereby the geg.- gle is secured in place. As the eye-cup construction thus far described is no part of my invention, further detailed description of the general wall formation of the eye-cup need not be entered into. i i

The eye-cups are usually made of a mould,- able material, such as bakelite, so Aas, to providethe wall with sufficient strength and rigidity while at the same time being `comparatively light in weight. 1

The wall at the outer or lens receiving kend on the eye-cup interior and somewhat removed from the outer perimeter is shown provided with an annular shoulder 13; while the interior of the cupbeyond the shoulder is shown threaded V,to receive the externally threaded flanged ring 14, whose iiange yis intended to lap the outer perimeter of the eyecup as shown; the ring'l4 being intended to hold the lens 15in place. Y

v The annular shoulder 13 is shown provided vvith a plurality of circumferentially spaced notches. .or grooves, as at 16, vdisposed transversely ofi the shoulder.; while the threaded main body portion of the ring 14 is likewise provided with plurality of cut-.out portions or slotsdisposed transversely .of the inner threaded portion `as t ShOWLl at 17 in Figures 2 and 5.

The lens 15, as clearly shown in Figures 1 and 2, is of a diameter materially less .than the diameter of the threaded portion ,of the eye-cup; and the lens 15V is provided .with a beveled perimeter 18 tapering inwardly toward the outer face of the lens, This beveled edge ofthe lens will cause the jlens'to be centered when the ring 14 is screwed-into contact therewith and as a result an annular space at 19 will be provided .beneath the Jring 14 and .Surrounding the edge ofthe .ansia '10 lao vided with the transverse notches or slots23.'k

extending through'the walls on opposite sides of the circumferential groove 22, see Figure |3; with the notches or slots 23 on the inner wall or perimeter of the ring extending down and through to the opposite sidep'or annular face of the ring 21, as shown at 24 see Figures 3 and 4; while the notches or slots 23 on the 'outer perimeter of the ring are of depth substantially equal to the depth of the annular groove 22'.

When the ring 21, which is of larger diameter than the lens, is arranged in the eye-cup vwith the annular groove 22 in the ring disposed toward the lens 15, the inner or lower ends 24 of the slots 23 will communicate with the goggle interior beneath the lens, while slots 23 will register or communicate with the annular space 19 with which the slots 17 in the lens holding ring 14 also communicate. It is apparent, therefore, that a plurality of continuous air passages, leading 'from the exterior to the interior of the eye-cup, or vice versa, will be provided as shown at in Figure 1.

Furthermore, these continuous passages 25 also communicate with the annular groove 22 in the face of the ring 21, thus allowing some of the air'to flow around'in the groove and to discharge through the lower or inner ends 24 of the slots 23. It is apparent that circulation of air through the eye-cup and across the inner side of the lens is permitted; and in order to permit such circulation, particularly in eye-cups as shown which are adapted to lit closely about the eyes, I show th-e side wall o f the eye-cup preferably provided with two screened openings at 26, 26.l

In my improved eye-cup, the lens 15 is not only' preferably beveled as shown and stated, but the lens diameter is also preferably sufliciently less than the inner diameter of the threaded Wall portion of the eye-cup so that the peripheral edge of the lens intermediate of the opposite bevels 18 and 20 will merely engage atthe inner peripheral edge of the Ventilating ring 21, as shown in Figures 1 and 2.

The lens, therefore, will not overlie or extend flush with the entire annular faces of the Ventilating ring and hence. will not entirely cover the ends'of the slots 23.

At the same time, with the slots 17 in the lens clamping ring made of sufficient depth as shown, the outer ends of these slots will remain uncovered and therefore permit air to enter the air space 19 beneath the threadled end of the lens clamping ring,see Figures 1 and 2, this air space in turn communicating with thev annular groove 22, which, in turn, communicates with the slots 23.

With the ring 21 arranged with its annular groove 22 disposed outwardly, namely toward the lens as shown in Figure 1, the maximum degree of ventilation is obtained.

. If for any reason a lesser amount of ven,- tilation or air circulation is desired, the

"wearer need merely remove lens clamping ring 14 and the lens 15 and then reverse the Ventilating` ring 21 by disposing the grooved side shown in Figure 3 inwardly or away from the lens, with the ungrooved side shown in Figure 4 disposed toward the lens as shown in Figure 2, and thus obtain a minimum degree of circulation, as a lesser amount of the air, which passes through the slots 17 in the lens clamping ring 14 into the air chamber or space 19, can pass through the uncovered portion 24 at the base of the slots 23 to the in-V terior of the eye-cup, or viceversa; this being possible because the extreme peripheral edge of the lens merely rests on the inner perimetrical rim of the Ventilating ring 21. p

It is apparent that the inner ends 24 of slots 23 in the ring will communicate with the goggle interior. Furthermore, as the slots 23 communicate with the annular groove 22 in ring 21, a minute amount of air will enter groove 22 and allowed to circulate through the slots 16 formed in the ring-seat or shoulder 13 of the goggle. As is evident, a lesser amount of air circulation is obtainable with the ring 21 arranged as shown in Figure 2 than is the case where the entire groove 22 is open to the annular air space 19 at the perimeter of the lens. f

It is apparent that although air circularoi tion about the lens is permitted, the passages a i are not only rather minute but of an indirect nature thus preventing passage of undesirable foreign particles.
