Description

Feb 79 T195@ w. WENTWORTH SPECTACLE SWEAT BAR Filed OCT.. 7, 1947 Patented Feb. 7, 1950 SPECTACLE SWEAT BAR Wilbur Wentworth, Cranston, R. I., assigner to Welsh Manufacturing Company, a. corporation of Rhode Island Application October 7, 1947, Serial No. 778,354

1 Claim.

This invention relates to an ophthalmic mounting, more particularly to a goggle or sun glasses, and has particular reference to the so-called sweat bar or cushion which is designed to engage the forehead of the user.

In the use of sun glasses of this character, it has been usual to provide a bar extending between the rims of the lenses at the upper edge thereof and a second'bar upon which a cushion is mounted to engage the forehead of the user. This cushion has consisted oi Celluloid or some like material, and diiiiculty has been experienced in the mounting of this material on the bar which extends between the lenses for its support. Various means have been provided for such mount- One of the objects of this invention is to reduce the number of metal bars which are provided in a pair of sun glasses of this character.

Another object of this invention is to facilitate the mounting of a cushion to engage the forehead on such sun glasses.

Another object of this invention is to utilize the metal bar which does connect the rims as a means for supporting the cushion in spaced relation along a majority of the length of it.

With these and other objects in view, the invention consists of certain novel features which will be more particularly pointed out in the appended specication.

In the accompanying drawing:

Figure 1 is a perspective view of the sun glasses equipped with this invention;

Figure 2 is a top plan view of the mid portion of the frame and with the outer ends of the frame broken away;

Figure 3 is a section on line 3-3 of Figure 2;

Figure 4 is a section similar to Figure 3 and showing a modified shape of cushion;

Figure 5 is a section on substantially line 5-5 of Figure 2.

In proceeding with this invention, I secure, in addition to the bridge between the rims, a metal bar at the upper edge of the rims and provide this bar longer than is necessary to extend between the rims so that the ends of the`bar may be turned rearwardly, and then I mount upon the ends so turned rearwardly, a cushion of Celluloid or some such material which acts as a second bar to engage the forehead. This Celluloid bar may be snapped into place by the resilience inherent in the bent-back ends of the metal bar and in the Celluloid cushion.

With reference to the drawings, III-TIII designates the rims of the mounting, which are provided with lenses I; a bridge I2 extends between the rims to hold them in fixed relation. Nose pads I3 are also provided for mounting the rims on the face of the wearer. Temples |4-I4 are hinged to the rims as at |5|5.

A raised connecting bar I6 extends between the rims lil- I0 and is secured to these rims at their' upper edges as at |I-|'I. The center of this bar I6 is bowed forwardly beyond the plane of the rims, as shown in Figure 2, while the end portions |8|8 of this bar I6 extend beyond the points of connection to the rims and are bent rearwardly as at |9| 9, and these rearwardly bent portions serve to support a cushion bar 20.

This cushion bar 20 is either of cylindrical construction, as shown at 20 in Figure 3, or of oval construction, as shown at 20 in Figure 4. This bar may be either solid Celluloid throughout a major portion of its length with recesses 2| or 2| in either end, or the bar may have an opening completely through it, axially thereof. These 1 recesses 2| serve to receive the end portions I9 of the bar I6, so as to mount this cushion bar in a spaced relation to the bar |6. This cushion bar, being rearwardlyv of the plane of the lenses and rearwardly of the metal bar IB, engages the forehead and serves as a so-called sweat bar when the glasses are in position on the wearer.

In order to position the cushion bar 20 or 20' in place, the ends and cushion bar will be relatively iiexed so that when flexed, the ends will be a sufcient distance apart to be received in the recesses 2| in the ends of the bar. This method of assembly permits a very simple and quick mounting of the Celluloid bar in place and yet presents the features which are desirable in the finished sun glasses for this purpose.

I claim:

In an ophthalmic mounting a pair of lens rims, a single bar xed to and extending between said rims at their upper edges, the ends of said bar being bent rearwardly and then back upon themselves in aligned spaced relation so that their end portions are parallel to and spaced from the plane of the lenses, and a sweat bar supported on said end portions by said end portions extending into the ends of said sweat bar.

WILBUR WENTWORTH.
