Application filed June 2G, i927. Serial No 199,960.

This invention relates to improvements in ophthalmic mountings and more particularly to that type of ophthalmic mounting known as goggles or eye protectors, and has special reference to acid proof ventilated goggles o r eye protectors, l

he principal object of the invention 1s to provide means for Ventilating the eye cups of such a device which will guard against the admission of acid or the like through ventilation of the eye cups.

Another object of the invention is to provide simple, facile and economical means for replacing such Ventilating means.

Another object is to provide simple, ellicient and economical means for holding the said Ventilating means.

Other objects and advantages of the invention will be apparent from the following description taken in connection with the accompanying drawings, and it will be understood that many changes may be made in the details of construction and arrangement of parts without departing from the spirit of the invention as expressed in the accompanying claims. Fife, therefore, do not wish to be limited to the exact details and arrangements shown, the preferred forms only having been shown by way ofillustration.

Referring to the drawings:

Fig. l is a front elevation of a pair o goggles embodying the invention. y

Fig. 2 is a cross section on line 2 2 of Fig. 1.

Fig. 3 is a similar cross section to Fig. 2 showing the parts partially in disassembled arrangement.

Fig. 4 is a partial perspective of a modilied form showing a shield embodying the invention hinged to the rims of a goggle. i

Fig. 5 is a cross section on line 5-5 of Fig. 4.

It has been usual in constructing eye cups for goggles and the like to provide the sides of the eye cups with wire mesh screens which are light and through which the air may pass to ventilate the interior of the eye cup to prevent the lenses from steaming and fogging, etc. It has been found in practice that where such protective goggles have been worn in work embodying Contact with acids and the like that the acid would penetrate the mesh screens causing injury to the eyes of the wearer.

It is7 therefore, the object of our invention to retain the advantages of ventilation and to provide in addition thereto means that will prevent the acid from entering the interior of the eye cups.

Referring to the drawings, wherein similar characters of reference are employed to denote corresponding parts, we have provided a goggle comprising a pair of eye cups l connected by a flexible chain link member 2 covered by a resilient nose pad 3.v The eye cups are held in position on the face by means of the head 'band 4. Each eye cup is provided with a lens holding rim 5 which holds the protective lens 6 inposition in the eye cup 1.

As shown in Fig. 2, the eye cup 1 comprises an outer mesh screen 7 and an inner mesh screen. 8 and between the two mesh screens is a fabric or other protective member 9 which may be made of cotton, fabric, silk, or other material having the property of allowing the transmission of air combined with the property of retarding transmission of liquid such as acid, water, etc. rlhe outer screen member 7 is held in place by a screw threaded retaining ring 10 to which the lens holding ring is threadingly engaged. The inner mesh screen is held by an inner retaining ring 11 which forms the bottom or support of the lens seat on which the lens 6 rests. The face contacting edge of the outerscreen member 7 is rolled into substantially circular form as shown in Fig. 3 and covered by a leather or other flexible member 12 which is secured thereto by sewing or otherwise to give soft and comfortable engagement to the face. The inner edge of the inner screen member 8 is held by a retaining ring 13 which rests on the face contacting member 12, as shown in Fig. 2.

The liquid ret-arding member 9 may be placed between the two screens 7 and 8, as shown in Fig. 3, the two screens being slidable one with respect to the other so that they may be separated and a new member 9 put in place and the two screens slid back into aligned position. This provides ready and facile means of replacing the member 9.

In Fig. 4 we have shown the invention applied to a hinge screen for a spectacle form of goggle, the screen carrying frame being hinged at 14. This arrangement makes a device that is easily detached at the pivots 14 tion member V9 as held between two screen members 7 and 8, it could be equally as well operable by being held by only one screen member and it could be placed either on the inside or on the outside of said screen member. lVhile we have shown our screen supporting members for the liquid protection member 9 consisting of a close mesh screen, it is clear that any fabric or member possessing qualities of admitting air could be supported by various other means to obtain the same result and function in the same way. The mesh could be much larger or separated supports could be used.

The operation of the device is as follows:

The air will penetrate through the screen support and the fabric of the member 9 while the acid or other moisture striking the member 9 will have a tendency to cause the fibers of same to expand or through the action of capillary attraction prevent the entrance of the liquid within the eye cup.

From the foregoing description it will be seen that we have provided simple, eflicient and economical means for carrying out all the objects ofthe invention and that we have provided an eye cup for an ophthalmic mounting, goggle or eye protection glass that will permit the transmission of air therethrough at the same time preventing the introduction of moisture, acid, water, etc., into the interior of the eye cup.

Having described our invention, we claim:

l. In a device of the character described, lens holding-means, a supporting member having separated spaces, means for connecting the supporting member and the lens holding member, a second supporting member having separated spaces lying within, parallel to and separated from t-he first supporting means, and a textile screen member having' the property of transmitting air and preventing the passage of liquids between the tw'o supporting members.

2. An ophthalmic mounting comprising an eye cup having lens holding means and a portion having a plurality of vent openings .and a textile screen held in place over the vent openings, said textile having a Weave adapted to transmit air and toprevent the passageof liquids therethrough.

3. In an opthalmic mounting comprising an eye cup having lens holding means and a vented portion, a second eye cup within the first eye cup spaced therefrom and having a. vented portion and a textile screen held between the two eye cups and over the vents, said textile having a weave adapted to transmit air and to prevent the passage of liquids therethrough.
