With reference to the drawing, the goggles oi.' this,invention are adapted to be mounted on a roi. a-ia traine which is placed upon and adjusted to the head oi the user. According to the present invention. this frame comprises an arcuate bottom strip iu, preferably formed oi' light metal and adapted to embrace the forehead and to entend alena the iront sides of the wearers head. The ends oi the strip It extend to about the middle oi' the head, and have attached at their ends a pair oi arcuate arms il and it which project towards one another and which are adapted to be connected, adjacent their ends, with an arcuate iront strip it. the lower end ol which is connected with the mid-portion oi the bottom strip lu. The upper ends ol all oi this three members il, li, and li are provided with a series oi' periorations it. and a suitable threaded holt 4It is adapted to be inserted through three superimposed periorations of the three members il, il, and ii aiter the head frame has been properly adjusted to the individual users heed.

Thereafter a wing nut it is tightened upon the boit ih ior holding the trarne in adjusted position.v The ends ol' the bottom strip Vi t have liliewise connected therewith strap means il, the outer ends of which may be adiustably connected by a buolrle it, or the like, in accordance with the needs oi' the user. -lt wiilbe seen in Fia. o that the strap means il may be continued around the inner face of the hottom strip It), as at li, ior contacting the head oi the wearer.

The goggles oi this invention are adapted to be mounted upon the front strip it of the head frame. Ii'or this purpose, the iront of the bottom strip Il! has connected therewith a bearing strip 2li formed with ap air of forwardly projecting lugs 2i. l.its seen in Figs. l and 6, the strip 2li may be secured, between the bottom strip m and the front strip i8 oi the head frame, all three parte being secured together by identical fastening means, such as rivets or by spot welding.

A bracket 22, formed with a pair of spaced arms 2B, is pivotally mounted between the lugs 2i. For this purpose, the upper ends of the bracket may be provided with a cross-piece 23 formed with a longitudinal bore. A shaft 24 extends through this bore and likewise through the lugs 2i for hingedly mounting the bracket. The arms 28 of the bracket 22 are formed at their outer ends to provide the angularly disposed portions 25 tor a purpose to be described. The extreme ends o! said portions 2B are connected by a bearing 21 in which the goggles are pivotally mounted.

Through the bearing 21, a rotatable tubular member 28 extends, the ends of the tubular member extending beyond the ends of the bearing, as indicated at 29, these projecting portions being exteriorly threaded. The tubular member 28 is retained in position within the bearing 21 by the means illustrated most clearly in Figs. 4 and 5. The said bearing is formed with a transverse slot 38 at the mid-portion of the front of the bearing. This slot may extend from substantially the top of the bearing to a distance slightly beyond the mid-point of the bottom side thereof. A set screw 3| projects through the slot 38 and is threadedly received in the tubular member 28, said screw extending outwardly beyond the surface of the bearing 30, whereby lateral displacement of the tubular member 28 is precluded and rotational movement thereof limited.

A pair of shafts 32 and 33 extends into the opposite ends of the tubular member 28, as seen in Fig. 4. These shafts are rotatable within the tubular member but are normally precluded from movement therein by virtue of a pair of packing nuts 34 embracing the shafts 32 and 33 and threadedly advanced upon the threaded ends of the tubular member 28 until the packing 35 in said nuts precludes rotational movement of the shafts within the tubular member.

The outer end portions of the shafts 32 and 33 are formed to extend rearwardly, as at 36, and downwardly, as at 31. the latter sections providing supports for the eye pieces 38 and 33. The vertical sections 31 are threaded and project through the tops of the eye pieces 38 and 39, a pair of nuts 48 and 4| being disposed on said sections 31 on opposite surfaces of the eye pieces and being tightened thereagainst for holding the goggles in the selected adjustment on their vertical axes.

Further details of the manipulation and adjustment of the goggles will be set forth below, but it will be obvious thus far that the bracket 22 may be swung down to the operative position seen in Fig. 1 and upwardly to the inoperative position seen in Fig. 3, and that the goggles, by virtue of their pivotal connection with the bearing 21, are adapted to be disposed in depending relationship in both'positions. For holding the bracket and goggles in their given position, the present invention provides for the use of an arcuate spring 42, the upper end of which is secured, as at 43, to the face of the front strip I3 above the bracket 22 and its mounting. The spring 42 extends downwardly over said bracket and bears resiliently against a cross-bar provided intermediate of the ends of the bracket and preferably taking the form of a roller 44.

A smaller arcuate spring 48 (Fig. 5) may be nxed, as at 48, to the rear part of the bearing 21,

the spring extending about the major portion of the slot 38 in spaced relation therewith. This spring exerts resilient -pressure against the outer end of the set screw 3| and precludes loose swinging movement of the goggles when the latter are disposed in their upper or inoperative position.

The use and operation of the invention may be further detailed as follows: 'I'he first step is, of course, to adjust the head frame to the size of the users head so that the frame fits fairly snugly. After the frame has been placed on the head and the buckle I8 secured, the goggles are swung to their downwardly extending position, as seen in Figs. 1 and 2. If the eye pieces 38 and 39 are too far apart or too close together for the individuals needs, the packing nuts 34 are loosened until the shafts 32 and 33 can be pushed in or pulled out, as the case may require, and furthermore, the exact pivotal adjustment of the goggles on their horizontal axes may be effected. For example. if the goggles, in their lowered position, do not bear evenly, all around, against the wearer's face, adjacent the eyes, the shafts 32 and 33 are rotated until the proper adjustment and "fee1ing of the goggles has been attained. It may be pointed out here that in the operative position of the goggles, the set screw 3| contacts the upper extremity of the slot 30 of the bearing 21 for limiting further pivotal movement of the goggles in this direction. The horizontal pivotal adjustment of the eye pieces 38 and 39 described above is made with the set screw in the contacting position mentioned. It may be that the eye pieces require a still further adjustment if it should happen that either one of them, or both, should project slightly below or above their most convenient or comfortable positions. If such is the case, the nuts, at 40 and 4| on the vertical sections 31 of the shafts 32 and 33, are loosened and either advanced or retracted for respectively raising or lowering the eye pieces. In addition, at this time, the exact pivotal adjustment of the eye pieces on their vertical axes may be effected. After such additional adjustments, the nuts 40 and 4| are again tightened against the top portions of the eye pieces and the latter are now in proper condition for comfortable and eflicient use. As will be noted in Fig. 2, a suitable. flexible shield extends between the eye pieces 38 so as to limit the entry of light under the eye pieces at the inner edges thereof.

. When it is desired to raise the goggles from the eyes, the unit comprising the eye pieces and the bracket 22 is simply swung arcuately upward until the bracket lies against the front strip l0. The eye pieces themselves, during such action, are not turned but rather are shifted as a whole, the bearing 21 rotating about the tubular member 28. At this time, also, the roller 44 on the bracket 22 rides upwardly against the inner face of the arcuate spring 42 and is resiliently pressed by said spring against the front strip i3 of the head f frame. 'I'he smaller arcuate spring 45, bearing against the outer end of the set screw 3|-, precludes loose swinging movement of the goggles in their raised position so that they do not hinge forwardly when the user bends his head, whereby inconvenience to the user and possible injury to the goggles are obviated.

The angular disposition of the outer end portions 25 of the bracket 22 is peculiarly effective for achieving a proper operative relationship of the goggles with the eyes of the user, and likewise, with the bracket assembly, resulting in a compactly disposed unit in the raised inoperative position of the device, as seen in Fig. 3.

As already suggested, the goggles may be raised from operative position, or returned thereto, with one hand of the wearer. This is a marked advantage since such manipulation of the goggles is frequently necessary while a workman is holding a tool, such as a welding device, in one hand. Moreover, the manipulation of the goggles does not in any way modify the preadjusted relationships of the various parts as already described, since the movement is simply a hinging or rotation of the tubular member 28 within the bearing 21. The manipulation of the goggles, it may be observed, is most conveniently done by grasping one or the other of the eye pieces and simply pushing it up, the goggles being held in sublill stantialoly a vertical position during such movement.

lt is an important'advantage of the present invention that the goggles may be worn comfortably over` regular eye glasses or spectacles. Heretoi'ore it has been necessary for Welders, grinders, and similar craftsmen obliged to Wear glasses, to have two pairs of them, one pair for use at work and one for ordinary use. The ones used at work usually must be replaced rather frequently, sometimes at the end of every few:

months, due to injury to the lenses by flying sparks, et cetera. The present invention obviates this additional trouble and expense. The goggles readily fit over the glasses and the outward arcuate movement of the goggles, when they are pushed up from the eyes, precludes displacement and injury to the glasses.
