I sclaims. (21. 2-14 Thislinvention relatesto goggles of the. type designed to protect the eyes ofithe wearer against dust, dirt and ,other. foreign matter, such goggles being used particularly byindustrial workers .of' various kinds such as in rwelding grinding and similar occupations where flying particles present an eye-safety hazard.

A fairly common type of safety goggle of this general class comprises a continuous generally oblong lens memberand a. frame or supportmember which fits about the periphery of the lens member and is secured thereto or interlocked therewith. The frame or support member extendsrearwardly from; the lens member, and its rear.

edge isr contoured to fit against the faceof the wearer, particularly against the forehead, the cheekbone and. the

- noseportionsofthe face;

Certain. prior art formsof safety goggles of this generalclasscomprise a framemember which extends about the "lens member with an.opening at'the bottom of the frame at apointiwhere the lens is notched'or otherwise formed-to accommo'date thenose of the wearer. An eX- ample'of safety goggles of this form is found in Taylor, etal. Patent No. 2,770,807.. In other formsof this general type-ofsa-fetygogglesthe framemember comprises a' continuous'loop which 'fitsentirely about theedges of the lens. memberhaving a-reentrant portion in registry withthelowercentral notchof the lensmember provided to accommodate. the nose ofthe wearer. Both of these general types. of safety goggles have distinct advantages.

I throughout the-nose notchofthe lens may fit better and be. more comfortable for, certain types of use.

' States P e t i 2,914,770 vPatented Dec. 1, 1959 whereby a softer or more flexible plastic material may be used for this portionof the frame to rest more easily on the nose of the wearer, it being understood that a relatively more self-sustaining material is required for. the'main framing portion of the goggles;

.Various modifications and mechanical advantages may be made in the goggles illustrated and described herein without departing from the principles of the present invention. Itis to be understood that the embodimentthus illustrated and described in detail is set forth by way of example and that the principles of the invention are not limited thereto or otherwise than as defined-in. the appended claims.

In the drawings: i

Fig, 1 is a general front elevational view of an assembled goggles of one form of the'present invention;

Fig. 2 is a side; elevational view of the goggles of Fig. 1 with the front portion shown as a vertical central crosssectional view; Fig.1 3 is a fragmentary bottom plan view of the central portion of the goggles of Fig. l; and

- fits over the edge oflens member 10.

The present invention provides a safety goggle arrangeing member in position the goggles possess all of the advantages of the continuous loop type of goggle frame but may be manufactured with greater facility and assembled about the lens with greater ease. Furthermore, the arrangement is such that the separate nose framing portion may be omitted or may be readily removed from y .the goggles as desired. This omission or removal may be for any of various reasons, for instance when a mask or inhalator is to be employed which would normally be interferred with by the nose framing portion of the continuous loop type of goggle frame.

A further important advantage of the separate nose piece frame member construction of the present invention resides in the fact that it permits the use of a different material for the nose piece portion of the frame In its Fig. 4 is an enlarged fragmentary cross-sectional view of one ofthe junctures of the two frame portions of the goggles of Fig. 1, the view being taken similarly to.

Like'characters of reference denote like parts in the several figures of the drawing and, referring more particularly to Fig. 1, a lens member 10' of transparent, rela-,

tively stiff, plastic or other material is horizontally ob.- long to cover both of the eyes of the wearer and is notched at its lower central portion to accommodate the wearers nose, all; as shown in, Fig. 1 and as is generally. known. in the. art. A main frame member 11 extends across the. top and sides of the lens member 10 andterminatesgenerally at the lower part. of the lens member at opposite sides of the nose notch thereof. As shown in Figs. 1 and 4' the lens member 10 is provided with a pair of hook formations 12 for interlockingengagement with the frame member 11 in a manner which.

will presently appear. Y

Therear edge of frame member 11 is contoured irregularly as indicated at 13 in Fig. 2 to fit againstv the,

trated-herein, aswill be seen from Figs. 1 and 4, channel formation 14 of frame member 11 terminates short ofnthe hook formations 12 of the lens member 10. Beyond the terminus of eachend of channel formation 14- the frame member 11 is slotted as at 16 in. Fig. 4 to fit over the companion hook formation 12 of thelens member and the end portions of frame memberll are preferably fianged as at17 to shroud or enclose the assembled hook formation 12 when the frame is in assembled position.

The nose portion framing member is designated 20 and generally forms a continuation of the main frame member 11, being provided in a similar manner with a channel formation 21 which fits over the edge of the nose opening notch in the lens member 10. The rear edge portion of nose framing member 20 is contoured as at 23 in Figs. 2 and 3 to more or less fit and rest upon the nose of the wearer and, as indicated in the preamble hereto, may be formed of a relatively soft plastic material to provide a comfortable nose rest portion.

The end portions of nose framing member 20 are notched as at 25 to fit over hook formation 12, being retained in assembled position over such hook formations by the overlying end portions of the main framing In the form illus- I member 11 as clearly shown in Fig. 4. The lens member is preferably notched as at 26 to accommodate such end portions of the nose portion framing member 20.

Thus in assembly the nose portion framing member 20 is merely placed in'position with its notches 25 assembl'ed ove'r the hook formations 12 of lens member and the-main framing member 11 is then assembled in the same manner as in the above-identified Taylor, et al. patent, such assembly of the main framing member automatically retaining the nose portion framing member in proper assembled position. If the nose portion framing member is not desired it is merely omitted in this assembly operation. If desired, the nose portion framing member 20 may be cemented or otherwise attached to the companion end of the main framing member in a more'or less permanent manner, either at one end or at bothends. While this does not permit ready omission of the nose portion framing member, it still affords certain manufacturing advantages and permits the use of a different material for molding the nose portion framing member than the material of the main frame member.

A head band 30 is attached to opposite sides of the main framing member 11 in an adjustable manner as shown in Fig. 2 and as is known in the art.

We claim:
