6 Claims.

'I'his invention relates generally to goggles, and more specifically to goggles of the type employed by workmen performing welding and like operations, the predominant object of the invention being to provide goggles of this type which are of such improved construction and arrangement that they perform their intended function in an improved manner while affording the users thereof greater convenience and comfort.

Prior to this invention Welders and other workmen whose eyesight required that they wear spectacles were at a decided disadvantage, due to the fact that there were no goggles available which could be used with comfort andconvenience while the wearers thereof were Wearing spectacles. Because of the great need for goggles which might be worn with spectacles, I have devisedthe improved goggles disclosed herein, which are so constructed and arranged that they may be placed in position before the eyes of a user thereof without interfering in any manner with his spectacles or with the normal use thereof.

The improved goggles disclosed herein include other features of construction which aid in making said goggles superior to the goggles now in general use. For instance, the support for the lens means is hinged so that said lens means may be displaced from before the eyes of the user of.

the goggles when said user of the goggles wishes to View the work being performed without the aid o'f the lens means. Also, the goggles include other important features of construction which serve to produce a greatly improved structure. i

In the drawings, wherein is shown for the purpose of illustration, merely, one embodiment of the invention, A designates the improved goggles generally. The goggles A include. a main frame 1, which at its front is provided with an opening 2 which preferably, ythough not necessarily, is of elongated rectangular shape. Extended rearwardly from the opening 2 are side walls 3 and top and bottom walls 4'and 5, said walls 3, 4, and

5 being preferably of integral construction. The side, top, and bottom walls of the main frame-follow the shape of the opening 2 at the front of said main frame; that is to say, saidwalls produce a rearwardly extending body which is of elongated rectangular shape. Also the side, top, and bottom walls of the main frame 1 are ilared outward- 65 1y, as shown most clearly in Figs. 2 and 3.

T he rear edge of the top wall 4 preferably has the approximate shape illustrated in Fig. 1, and said top wall is provided with an upstanding portion 6 which contacts with the forehead of 70 the wearer of the goggles in a manner to aid in supporting the goggles in their proper operative position onl the face of the wearer. Also, the bottom wall of the main frame is shaped as shown in Fig. 3, and i'svprovided with an upward- 75 l 1y and rearwardly extended flange '7 (Fig. 5), said flange being so shaped as to receive and rest upon the wearers nose and in this manner aid in the support of the goggles. The nose flange 7 merges into the rear edge of the bottom 80 wall, as shown in Fig. 3, said rear edge of said bottom wall being shaped so that it conforms to the shape of the Wearers face at the cheek bones', whereby substantially light-proof contact between the 'rear edge of the bottom wall and 85 the wearer's face is provided. The same is true of the rear edge of the top wall 4 of the main frame 1, said rear edge of said top wall con'form-y ing to the shape of the wearers forehead so as to provide substantially light-proof contact between the rear edge of the top Wall and the wearers forehead. The main frame l is pref- .erably made of bakelite or other suitable relatively light material.

At the fro'nt thereof the main frame 1 is pro- 95 vided with a. rectangular depression 8 which surrounds the opening 2, as vshown in Figs. 2 and 3'. This depression receives a supporting member in the form of an elongated rectangular frame 9, which supports one or more lenses l0. The particular frame 9 illustrated in the drawings is produced from tubing of substantially round cross-section, and the inner portion of the depression 8 is rounded to receive a frame of such cross-sectional shape, as is shown clearly in Figs. 2 and 3. The frame 9 is composed of an upper tubular element 9, a. lower tubular element 9b, and oppositely disposed end tubular elements 9, said elements being secured together by bolts 11 (Figs. 1, 3, and 4) which extend through aper- 1-10 I .so

tures in the wall portions of the top 'and bottom elements and pass longitudinally through the end tubular elements 9. Each bolt is provided with a head at its upper end and receives one or more nuts 11 .at its opposite end. A

The upper elements 9a of the frame 9, at the opposite ends of said frame, extend beyond the opposite end elements 9 of the frame; and these extended portions are located in bearing portions 12 formed at opposite sides of the main frame 1 of the goggles. 'I'he walls of the cavities within the bearing portions 12 are screw-threaded, and said cavities receive externally screw-threaded elements 13 which are each provided with an inwardly extended rod 14. The rods 14 are extended into the adjacent end portions of the upper tubular element 9a of the frame l as shown in Fig. 4, whereby said rods provide pivot or hinge elements with respect to which the frame 9 is hingedly movable. At its opposite ends the upper tubular element of the frame 94is provided with annular flange portions 15, and expansible coil springs 16 are interposed between said flange portions and the externally screw-threaded elements 13, as shown in Fig. 4. These coil springs serve to apply friction to the flange portions so that the frame 9 will remain in an elevated position to which it has been moved.

The opposite ends of the lower tubular element 9b of the frame 9 also are extended outwardly beyond the end tubular elements 9. These `extended portions receive members 17 having rounded outer end portions which improve the appearance of the frame 9 and serve as convenient handle elements which are useful when the .frame 9 is being raised to an elevated position. The side walls of the main frame are notched to receive the extended portions of the lower tubular element 9b of the frame 9, as indicated at 18 in Figs. 1 and 4, and also the bottom wall of said main frame is provided with depressed portions 19 which receive'the nuts 11 associated with the bolts 1l when the frame 9 is in a lowered or closed position.

'I'he frame 9 is provided with a continuous opening 20 into which the edge portions of the lenses 10 are extended. In the drawings I illustrate two lenses which are separated by strips 21 of fiber or other suitable material. Located within the tubular elements 9, 9", and 9 of the frame 9 are strips 22 of fiber or other suitable material with which the edges of the lenses 10 contact Vso as to properly position the lenses 10 within the frame. The strips 22 within the end tubular elements 9 of the frame 9 contact with the bolts 11, as indicated most clearly in Fig. 4, and the strips 22 within the upper and lower tubular elements being slightly flexible serve to take up expansion of the lenses 10.

Fixed to and extended rearwardly vfrom the main frame 1 are elements 23 formed of fiber or other suitable material. These elements embrace the sides of the face of a wearer of the goggles, being shaped to conform to the shape of a face so to provide close contact therewith and thus exclude light from the interior of the goggles. The elements 23 are secured to the side, top and bottom walls of the main frame 1 by means of suitable fastening devices 24 and 24 and a suitable head-embracing band 25 is attached to said elements 23. Located within the main frame l is a vent shield 26, which is secured to the upper,'lower, and side walls of the main frame 1 by the same fastening devices which attach the elements 23 to said main frame. The vent is shaped with respect to the main frame 1 so that a ventilation space 27 is provided which extends about the top, ends', and substantially the entire bottom of the elongated opening 2 at the front of the main frame 1, this ventilation space being interrupted at the center of the bottom of said opening by the nose-receiving flange 7 already referred to herein, which interrupts the continuity of the vent shield at the bottom of the opening 2. The forward edges of the vent shield are seated in a depression 28 formed in the main frame 1, as shown in Figs. 2 and 3, sol as to provide a light-proof joint between these elements. Also, the top and bottom walls of the main frame l are provided with ventilation apertures 29 formed therethrough which communicate with the ventilation space 27, and the vent shield 26 is provided with like ventilation apertures 30 formed through the portions thereof at the opposite sides of goggles which also communicate with the ventilation space 27.

In the use of my improved goggles, said goggles are arranged in place on the face of the user in the usual manner, the band 25 being caused to encircle the users head so as to retain the goggles in position, and the dimensions and shape of .the goggles are such that the goggles may be employed while the user is wearing spectacles without interfering in any manner with said spectacles.v The goggles are employed, of course, with 105 the lens frame 9 in a lowered or closed position, and when the workman desires to view the work being done without the aid of the lenses, he merely swings the frame upwardly, as indicated by dotted lines in Fig. 2, and the con springs 16 110 will retain said' frame in such elevated position. During use of the goggles air will pass through the apertures 29 formed through the top and bottom walls of the main frame into the ventilation space 27, such air then passing from said ventilation space into the interior of the goggles -v through the apertures 30 formed through the vent shield 26. 'I'he advantage of utilizing the vent shield 26 instead of bringing Ventilating air directly into the interior of the goggles through the apertures 29 is that passage of light into the interior of the goggles through the apertures 29 is prevented by said vent shield.

It will be noted that the fastening devices 24' extend through enlarged apertures 24 formed 125 through .the elements 23. This arrangement permits the rearmost end portions of the elements 23 to be adjusted toward and from each other so as to fit faces of different widths, as suggested by dotted lines in Fig. 3.

In Figs. 6 and 'Z I illustrate a shield 31 which may be employed when the goggles are used in electric welding work to exclude bright flash rays of light from entering the goggles through the joints between the lens frame and the mainframe. 'I'his shield 31 comprises a rectangular member which is shaped to cover the front face of the main frame and the lens frame, said shield having a rearwardly extended marginal flange por- -ticm 32 which contacts with the forepart of the 140 top, bottom, and side walls of the main frame. 'I'he shield 31 includes a pair of rearwardly extended extensions 33 having apertures formed therethrough through which the bolts 11 are extended, said extensions 33 being interposed between the nuts 11( at the lower ends of said bolts. Also, to aid in retaining the shield 31 in place on the goggles, I may employ one or a pair of retaining springs 34 which are wound 9199@ the extended end portions of the lower tubular element of the lens frame and contact with the shield 31 at elevated points.
