GOGGLES.

Application filed August 8, 1921. Serial No. 490,538.

To all whom it may concern:

Be it known that I, ROBERT MALooM, a citizen of the United States, residing in Chicago, Cook County, Illinois, have. invented certain new and useful Improvements in Goggles, of which the following, taken in connection with the drawings, is a description.

My invention has for its object the production of a pair of goggles having eye cups or lens-holders for the goggles which shall be simple and cheap in construction, comprise few parts, and be very efficient for the purpose intended.

One of the objects of my invention is to provide a metal rim which may be cut 01 stamped out of a flat, preferably a round piece of material, an opening cut therein to receive the lens and the edges of each metal rim being bent to form a circumferential groove which receives and holds the goggle lens in place without any further fastening device.

A further object of my invention is to form the side members of the lens-holding cup of a flexible material having a wire extending around the outer edge thereof and which forms a spring for distending the frame when in use, permitting it to fold close to the lens-holding rim when desired to place it within a small compartment when not in use.

In the accompanying drawings I have il lustrated what I now consider an embodiment of the preferred form of the essential features of my invention and in these drawings:--

Fig. 1 is a front elevation of a pair of goggles embodyingmy invention,

Fig. 2 is a side view of the same,

Fig. 3 is a plan View of the blank from which the lens-holding rim is formed and- Fig. i is a sectional view taken through the lens and the elongated side of the frame.

Referring to the drawings A represents the blank from which the lens-holding rim is first cutor stamped in the form of a circle as shown in Figure 3. On the bending machine the frame thus cut from a flat piece of material is bent to the oval contour shown in Figure 1, the inner edge thereof a being bent to form a shoulder fitting over or around the edge of the lens B, shown more clearly in Figure 4:, the bending of the inner edge of each rim shaping it into an endless circumferential groove. The lens B is securely held in this groove after being placed therein, the outer edge a being bent more closely around the edge of the lens as shown in the drawing.

The cup portion of the frame B is preferably formed of fabric, but may be of any other flexible material, which is elongated on one side thereof on a line diagonal to the axis of the eye-cup, to fit around the eye and extend backwardly on the temples of the wearer. The circular edge of this eye cup has secured therein a wire Z) extending circumferentially of the eye cup and is placed within the groove formed by bending the edge of the rim A inwardly as shown in cross section in Figure 4;. A loop 6 is formed in this wire 6 which projects through openings c0 in the rim A near the nose bridge. The wire Z) is bent in circular form larger in diameter than the lens and is sprung into the groove provided for it and holds the same in place.

The wire 0 extends around the edge of the fabric forming the eye cup and expands it to the position shown in Figures 2 and f. Vi hen desired to fold the eye cup into smaller space it can be bent down closely to the lens and will occupy very small space in the box or enclosure provided for it. A rubber band or cord 0 is secured to the elongated sides of each of the veye cups and extends around the head of the wearer to 'hold the goggles in place when worn.

is preferably formed of rubber.

It will be' observed that the structure I have devised is exceedingly simple, comprises few parts' and the formation of the lens-holding rim presents a very advantageone feature of construction in forming a rim from a circular piece of n'iaterial which is bent to the oval contour and formed into a groove to receive the lens and the edges of the eye. cup frame which are securely held therein simply by the bending of the edge of said rim and without any other fasten ing means.

In a pair of goggles, the combination of eye-cups formed of fabric material mounted on flexible resilient. frames to hold same in distended position, lens-holding rims, each having a circumferential groove therein adapted to receive the edge of the eye-cups, a lens seated in each groove, the edges of said rims being bent to retain said lenses and eye-cups in frictional engagement, said lensholding rims having openings in one side thereof, a Wire secured at the circular edge of each fabric eye-cup for holding the same in distended position and thus permitting the circular edges of the eye-cups to he sprung; into and removed from the circum- .lierential grooves of the rims, said spring Wire in each instance extending through the openings in the rims in the form of a loop upon the outside of each rim, and a flexible nosepiece having the opposite ends thereof connected to the Wire loops extended from a pair of said rims.

In testimony whereof I have signed this specification.

ROBERT MALCOM.
