EYE PROTECTOR.

Application filed July 30,

The present invention relates to an improved eye )rotector and to the process for forming the same. I

An important object of the invention is to provide an eye protector having particular reference to a curved auto goggle, wherein a lens may be associated with an eye cup in such a manner that it will be held in position when in use, while at the same. time it may be easily and conveniently removed when desired.

Another important object of the invention is to provide an eye protector of this character which will be exceptionally light, thus permitting its use for a long time without causing any discomfort to the user.

Another important object of the invention is to provide a goggle of this nature, and process of forming the same, whereby such a goggle can be made much more inexpensively than has heretofore been done because of the fact that less material is wasted and that the manner of manufacture is reduced to the simplest way possible.

Other objects and advantages of the invention will become apparent during the course of the following description.

In the drawings, wherein like numerals are employed to designate like parts throughout the same:

Figure 1 is a front elevation of a pair ofgoggles constructed in accordance with the present invention Figure 2 is a fragmentary perspective view of the goggle illustrating the lens par tially in position.

Figure 3 is a similar view showing the lens locked in position for use;

Figure l is a fragmentary sectional detail showing one manner of mounting the lens;

Figure 5 is a similar section showing a slightly modified form;

Figure 6 is a view of the construction shown in figure 5 after the lens has been fastened in position;

Figure 7 is a top plan of another form of goggle.

In the drawings, wherein for the purpose of illustration is shown the preferred em bodiment of the invention, the numeral 10 designates a goggle in its entirety, which comprises the cups 11 having the lenses 12 therein, the said cups being connected together by a bridge portion 13 and having 192%. Serial No. 729,086.

a head band 14 for holding the same in use uponthe head of the user when desired.

This particular type of goggle is designed for use particularly as an automobile and motorcycle goggle, and to this end a form of goggle is constructed that will give a large field to look through so that the goggle will not hinder the user when in actual use.

l 'he cups in the present instance are preferably formed from a single length of material 15 as shown in Figure 2, the said material being perforated as at 16 for the purposes of ventilation, and having the slots 17 therein to permit of the connection of the bridge portion 13. Prior to the formation of the strip into the form of a'cup,vit is suitably out out to form the curved edges 18, which edges are so formed as to fit snugly against the face of the user without any discomfort to the user. After the strip 15 has been shaped and perforated as described, it is bent, preferably into the form or shape of cup as shown in Figure 1. The ends of the strip overlap, as at 19, and are held together by means of rivets 20, which rivets have the rounded heads, as clearly shown in Figure 2, projecting on the outer surface of the cup. The lens may be held in the cup in one of two ways, that is, as is shown in Figure 2 and a, by forming a groove 21 in the two sides and nose end of the cup, having the outer end reduced so that a lens 22 can be inserted in the groove 21, as is clearly shown. A pivoted latch member 23 is connected to the cup by the pins 2d, and is provided with the detents 25 so that when the latch 23 is swung into operative position the detents 25 will engage the rounded head of the rivets 20, thus preventing accidental displacement of the catch and holding the lens in positionw In the other case the lens 22 is placed in the cup, as shown in Figures 5 and 6. In this instance an offset portion 26 is provided and after the lens has been placed in position, as in Figure 5, the offset portion is rolled over the lens to form the head 27.

I preferably form the eye cups from a cellulose composition material so that the cups will be light and also for the reason that the cellulose composition material can be made transparent, thus permitting of a light construction containing a lens, while at the same time it does not in any way-cut off or interfere with the natural vision of the user. Thus, in the instances where a cellulose composition material is used, when it is desired to remove the lens from the head 27, it is merely necessary to heat the cup and the bead can then be rolled back, the lens removed, and a new one rqalaced.

Attention is called to the fact that a considerable amount of material and time is saved in constructing the cup from a strip of material which is perforated, grooved and shaped prior to its formation into the cup, while at the same time the round headed rivets Q0 serve a dual function, namely, they act to hold the interlappii'ig ends 19 together and form means to engagethe pivoted latch 23 to prevent displacement of the latch when the lens 22 is in position and the latch swung down for use.

The cup can be shaped in any desired manner and can be of any configuration, as will readily be understood.

It is to be understood that the form of the invention herewith shown and des tribe-d is to be taken as the preferred embodiment of the same, and that various changes in the size, shape and arrangen'ient of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. An eye protector of the class described, comprising a pair of lens holding frames, each of said frames being formed from a length of material, the ends of which overlap, means to hold the ends together, and a pivoted catch engageable with the said means when in operative position.

2. An eye protector of the class described, coinprising a pair of lens holding frames, each of said frames being formed from a length of material, the ends of which overlap, means passing through the said ends to hold them together, and having knobs carried thereby and a pivoted catch carried by the frame and engageable with the said knobs to hold the same in operable position.

An eye protector of the class described, comprising a pair of lens holding frames, each of said frames being formed from a length of material and having overlapping ends, means to prevent separation of the ends, and having knobs thereon, a pivoted catch carried by the frame and engageable with the knobs to hold the same in operative position, the said frame having a lens receivng groove formed therein.

41-. An eye protector of the class described, con'iprising a pair of lens frames, each of said frames being formed from a length of cellulose composition material, the ends of which overlap, means passing through the ends to prevent separation thereof, knobs :arried by the said means and a pivoted catch carried by the frame and having a portion engageable with the said knobs to hold the same in operative position.
