4 Claims. (01. ss 4s) This invention relates to a goggle and more particularly to that portion of the goggle which rests against the head of the wearer as a support for the device at this location.

In the manufacture of goggles having supports of this character, there is provided a non-metallic piece of material which is mounted upon a metal rod that extends from one lens to the other, with this non-metallic material at such a location that it will engage the forehead just above the eyes of the wearer to provide a support for the goggles should the goggles be urged toward the face of the wearer. In order to provide such a non-metallic support on the rod, the non-metallic support, if in one piece, must be positioned on the rod prior to the soldering f the rod to each of the rims in which event the solder joint shows as the coloring of the metallic parts of the goggle cannot take place after the non-metallic cushion is positioned without damage to the cushion. Further, if the non-metallic parts are assembled on the bar after the parts are secured in position, the cushion must be in two parts and a long and tedious operation of mounting the cushion in place is necessary.

One of the objects of this invention is to provide a device so that all of the metallic parts may be attached and in place and then the non-metallic cushion may be thereafter positioned while in a one-piece tubular form on the metallic rod which receives it.

Another object of this invention is to provide a method of assembly of the non-metallic cushion and the metallic parts of the goggle so that the metallic parts may be colored without the cushion in place and the cushion thereafter assembled by a very simple operation.

Another object of this invention is to speed up the production and reduce the cost of operation in the manufacture of goggles having this type of equipment.

More specifically an object of this invention is to provide a non-metallic cushion which serves as a means for supporting or joining the parts which heretofore served as its support alone.

With these and other objects in view, the invention consists of certain novel features of construction as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

Fig. 1 is a face view of the goggles;

Fig. 2 is a top plan view thereof with the temples broken away;

Fig. 3 is a top plan view of the goggles with the non-metallic cushion removed and illustrating in dotted lines the severingof the stock of the supporting rod;

Fig. 4 is a view similar to Fig. 3 showing in section a cushion being positioned on the supporting rod;

Fig. 5 is a perspective view of a length of stock from which the tube is formed;

Fig. 6 is a perspective view of the tube;

Fig. 7 is a perspective view of the structure of Fig. 6 after being flattened;

Fig. 8 is a section on substantially line Fig. 2 on an enlarged scale.

Fig. 9 is a top edge view of the goggles with the cushion of modified construction in section.

Fig. 10 is a view similar to Fig. 9 showing the cushion being positioned on the supporting rod.

Fig. 11 is a sectional view of the cushion of Fig. 9 alone.

Fig. 12 is a section of Fig. 11 before flattened.

Fig. 13 is a section line I 3i3 of Fig. 11.

In proceeding with this invention, I solder the ends of either one or two pieces of a metal supporting rod to the upper edge of the rims of the goggles which is to serve as a support for the cushion, and then the goggle is colored or plated to provide a good finish on the same. Thereafter, a cushion is provided with tubular ends, the rod is severed if previously in one piece to provide two bars, and the cushion is slid onto one of the bars a sumcient extent so that the other bar may be received. The bar is then moved back into alignment with the other bar and the cushion is then slid back over the other bar and cemented in place. Out-of-round sections are provided for preventing rotation of the cushion on the bars.

With reference to Figs. 1-8 of the drawings, l'l designates the lens rims which are joined together by the bridge ll upon which arms l2 are provided for supporting nose pads it which nose pads may be of non-metallic material. End pieces M are formed on the outer edges of the rims from which temples l5 extend rearwardly.

A support for engaging the brow of the face of the wearer above the eyes is designated generally it and consists of a rod ll (see Fig. 3) which is soldered or otherwise suitably secured as at ends it and ill to the rims it; and the frame is then plated or colored to provide a suitable finish; and, thereafter, the rod il is severed at 2i? so as to provide a bar 2! attached as at it and a bar 22 attached as at l9 which bars extend toward each other and are in general alignment after severing. The location of severing will be such that the bar 22 is of a length to receive the cushion.

A cushion formed of some non-metallic material, such as Celluloid, is available in solid rod form, designated generally 23 in Fig. 5, and may be formed into a tube, as designated at 25 in Fig. 6, having a bore 25 extending therethrough. This may be accomplished by a screw machine operation by drilling in through the opposite ends of the rod; and, thereafter, the tube 24 will be flattened, as shown at 25 in Fig. 7, so as to provide a somewhat oval hole 2'1 through the same (see also Fig. 8). The bars 2i and 22 or rod i! will be rectangular or of some shape, such as designated 28 in Fig. 8, so that when the c.ushion.2fi is positioned on these bars it cannot rotate.

To assemble the cushion ltion the structure,

as described above, it is merely necessaryitoraise the bar 22 outwardly from alignment with the bar 21, as shown in Fig. 4, and slide the cushion 26 over the end of the bar 22 into a position, such as shown in dotted lines in Fig. 4. Then, the bar 22 may be moved back into alignment with the bar 2! and the cushion 28 slid back over the ends of the bars 2i and-22 to the position showninFigs. 1 and 2 with the longest axis .of the. oval hole 21 substantially in the plane of Cement will then be applied to rnaintainrthe non-metallic-C'elluloid cushion :25 in the the rims.

position which it has been moved to on the bars. The cushion thus serves to connect the bars togather and ,provides its own support for the bars in maintaining the desired rigidity of this support which may rest against the face of the wearer.

With reference to Figures 9 to 13, the rims it have harsiii and 3! soldered to each of the rims as :at 32.,and .33, these bars being spaced a conand :slid so that the bottom of its bore 38 will engage the end of the bar 30, the bore 33. being of such a depth that. when the. cushion36 is swung inwardly from the position shown in Figure 10 to that shown in Figure 9, the bar 31 may be received in the bore 39. Thus, as the cushion 38 is swung inwardly, the bar 3i is moved into the bore 39 and the cushion adjusted on the bars 38 and 3| until it assumes a position shown in Figure 9.

In some cases the cushion 36 instead of being cylindrical, as shown in Figure 12, may be flatiten'de'd soas'to take thEOlltdf-I'Olllld shape 40, as shown in Figure 13, in which case the opening or bore will be flattened as at 4!, and in this -ease the bars 30 and 3| will be of a similar outof-round shape to fit into this bore and prevent rotation of the cushion on these bars.

I .:claim:

'In-a goggle apair of lens rims, means connecting said rims, brow support located rearwardlyofsaid .rirnsand extending from the upper edge of one rim to the upper edge of the other rim and comprising one bar attached to one rim and a second bar attached to the other rirn, saidbars extending towardeachzothenand a non-metallic. cushion having tubular sections at its end :portions embracing :the inner .end 1pertions of said bars and serving as the sole means toconnect said bars and provide rigidity ts said support.
