W. P. BIGGS EYE PROTECTOR Filed NOV. 15, 1955 izf'fv'" g //.5 Q n 6 W. RBIGGS INVENTOR Maw ATTORNEY Patented Jan. 17, 1939 UNITED STATES PATENT OFFICE 1 Claim.
(Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) This invention relates to a goggle or the like and has among its several objects: To provide a cheap yet effective article of the type above mentioned; to provide an eye protector in which the lenses are readily insertable and removable but are nevertheless safely retained; to provide a goggle wherein the body and the straps for retaining the protector in operative position on the face of a wearer are made integrally; and to provide in the eye-cup a recess or trough for holding water that may, by a rapid forward inclination of the head, be swished over the inner surface of the lens to remove steam or other sight-obscuring materials adhering to the inner surface of the lens.
In the drawing:
Fig. 1 is a face view of an embodiment of the present invention;
Fig. 2 is an edge view with one eye-cup in section; and
Fig. 3 is an enlarged detail view of an eye-cup on the line 3-3, Fig. 1.
It is to be understood that the terms lower, outer, etc., as used hereinafter to designate relative positions refer to the positions of the parts of the device when it is being worn.
The eye protector embodying my present invention comprises a substantially flat body portion 4 which includes narrow, elongated strap members 5 adapted to pass around the back of the wearer's head and are secured together by any suitable means to retain the goggle in position on the face. The body and straps are normally flat, as may be seen in Fig. 2, and are of soft, very flexible rubber that readily adapts itself to the configuration of a wearers face and clings closely so that dust and other deleterious matter are completely excluded from the eyes. The lateral edges of the body may be provided with beads 6 to prevent ready tearing of the soft rubber. The lower edge of the body is formed with a reentrant portion 1 to adapt it to the nose of a wearer and adjacent thereto a the ribs 8 extend from the upper edge to the bead at the said portion.
The eye-cups 9 may be, and preferably are, formed integrally with the body 4. At the outer end of each eye-cup is a thickened bead l0, having in it an internal annular groove II which gives to this part a substantially U-shaped cross section. The beads 10 are of flexible rubber to permit the ready insertion or removal of the lens I2 but, owing to the thickness of the bead, they are sufliciently rigid to retain the lenses safely while the protector is being worn. The edge of each lens I2 is formed with a double bevel, the 5 portion l3 sloping toward the inner surface of the lens being considerably longer than is the portion l4 sloping toward the outer surface thereof, thereby facilitating the insertion of the lens into the eye-cup groove and its removal there- 10 from but providing a sufficient bearing surface between the outer face of the lens and the wall of groove H to insure against casual removal of the lens. The soft rubber in the bead [0 tends to adhere to the lens and so assists in the re- 15 tention thereof.
In the lower side of each eye-cup 9 is form a trough or recess IS, the wall of the eye-cup being thickened as shown at IE to provide the requisite depth. Of course, if desired, the trough l5 might be formed by depressing the wall of the eye-cup below its normal contour and without the thickening as shown in Fig. 3. A small quantity of water may be placed in each trough l5 and when, during use, the lenses become fogged with steam or moisture from the wearers face, or if any other sight-obscuring substance should gain access to the eye-cup and adhere to the lens, the inner surface of the lens may be washed by rapidly inclining the head forward to cause the water in the troughs I 5 to swish over the lens and so remove the adhering material.
The invention described herein may be manufactured and used by or for the Government of the United States for governmental purposes without the payment of any royalties thereon or therefor.
Eye-protecting goggles comprising a body portion having eye openings therethrough, means for securing the body portion over the eyes of a wearer, eye-cups secured over the eye openings in the body portion, a sight transparency closing the outer end of each eye-cup, a flange extending upwardly at the front of the base of each eye-cup and at the rear of the sight transparency, and a flange extending upwardly at the rear of the base of each eye-cup, said flanges providing a pocket for receiving condensation-clearing fluid.
