This yinvention relates to goggles to-protect the eyes of persons engaged in `industrial pursuits from intense light, dust, flying sparks, and other injurious substances, and also to goggles ior general use.
Among the objects of the invention .are v.to
provide a wide-vision article .of this class that includes protective lenses that are reliablyheld in place and yet are easily removable, after impairment for replacement by others, without use of a tool, one that can be Worn over ordinary spectacles or other ophthalmic devices, and one that can be folded when not in use so that it ...can be carried in a garment pocket. Y
The invention also is directed to provision :of a single means for retaining each lens 4in .place and for attachment of a headband.
Further, the invention -providesgog-gle frames or-eyecups having Ventilating vents sofformed and positioned that dust is notapt to enter.
The eyecups of the .gogglesadvantageously may be made of resinol or other suitable light and strong moldable material. Another object .is to provide a goggle eyecup with parts .so arranged and shaped that it can be molded easily by a twopart mold.
When considered with the ydescription herein. characteristics of the invention are apparent in the accompanying. drawings, formingpart hereof, wherein adaptations are disclosed for .purpose .of illustration.

Fig. 10 is a view illustrative of another form of lens retaining member;
Fig. 11 is a section on line II-I I, Fig. 10;
Fig. 12 is a section on line I2--I2, Fig. 11;
Fig. 13 is a view illustrative of an optional method of holding the latch in locked position.
Each eyecup is in the form of a frame consisting of upper and lower substantially parallel walls eye, and end members I6 and I'I .connecting those walls. Theframe is-generally rectangular, except at thenasal end where the .lower member .I5 eX- tends upwardly ininclined disposition and merges into the end -member lli Vto provide an end .surface, as indicated by |13, .to conform to and contact with theside of the .wearersnose The .eyecup appears as a rectangle with one .corner omitted. The eyecup is arcuate in ,front-that is,
it curves outwardly :between the end members The upper .and lower members of `the frame are formed with inside .oppositely disposed spaced ilanges I9, the `endmember It has .an Vvinwardly extending flange 2B, and these flangeshave outer surfaces lying in the arc of a circle. The end member I6 has abutments 4Z'I constituting stops.
The upper and .lower frame members also Vare formed, at yor near .their outer edges, withinwardly extending ngers 22, which are opposite'ly disposed and are positioned .over the intervals between the iianges .I 9.
The under or inner `surfaces of the fingers lie in the arc of a circle of greater diameter than that of the outer surfaces ofthe flanges IS, the difference being approximately that of the thickness of a curvilinear lens 23, which 'is slidable in the Vgroove afforded by the anges and lingers. The lens in plan corresponds to the inside shape and dimensions of the frame in which it is `dii.- posed. When in normal position, one end of the lens rcontacts the stops `2| of the end member I6.
I The `other end of the lens V.then extends .slightly overthe end member I Iv of the iframe.
It 'is to be nunderstood that, while the goggle glass, is Areferred 'to 'as Va, lens, it is'intended to vdenote any glass 'or other Vsuitable transparent pane that may be used.
The inner sides of the frame members Ill and I5 have channels or grooves 24 extending inwardly from their outer edges between the fingers 22 to channels or grooves 25 in the anges i9, these channels or grooves constituting Ventilating vents between the edges and the under marginal surface of the lens. It has been found during use that vents so formed and located, while affording satisfactory ventilation to the inside of an eyecup, do not permit entry of appreciable amounts of dust thereto.
The lens is retained in place by a locking member or latch '26. When in locking position, its ends rest on the two flanges I 9 at the juncture of the end frame member Il' With the upper and lower frame members l4-I5,` its inner edge 21 contacts with the end edge of the lens, and it has an outer lip 28 that laps the outer marginal surface of the lens and inner lugs 29 that lap the inner marginal surface of the lens, the lip and lugs affording a groove in which the end of the lens seats.
The latch member 26 may be held in lock position with respect to the lens by a headband 30, preferably one of at or tapelike ilexible form having an enlarged end 3|. The band is reeved and drawn through a slot 32 in the member 2E until stopped by the head 3|, and the band also is disposed through a slot 33 in the end frame member |1. When the band is pulled through the slot 33 until the edge 21 of the member 26 is brought against or near to the edge of the lens, that member is in normal or lock position, and the end of the lens seats in the groove between the lip and lugs of the latch member.
Usually the headband is of rubber and of a size to resist its movement in the slot 33, with the result that the band holds the latch in lock position even when it is not under tension around the head of a wearer. However, if a tape, cord, or other elongated flexible article other than a headband is used to keep the latch locked, it may be tied, as shown in Fig. 13, or otherwise attached to the end frame member I1.
When a lens is to be removed, the latch member is pulled away from its normal position and enough of the headband through the slot 33 to free the lens and permit it to be withdrawn from the eyecup, as seen in Fig. 8; or, if a tied latch locking article is used, it may be untied to release the latch. With the latch unlocked, another lens may be inserted and the latch then drawn back to lock position.
Anotherl form of lens lock is exemplied by Figs. and 11. It comprises a substantially flat plate 34 held by a bolt 35 extending through the end frame member I1 and a finger nut 35. The parts are proportioned and arranged so that, when the nut is tightened against the plate, one outwardly flared edge 31 of the latter presses against an end of the lens. The plate has lugs 38 contactable with terminal ngers or ilanges 39 of the frame member I1 to prevent rotary movement on the bolt. The plate has a slot 40 or other suitable opening therethrough in its outer end for connection of a headband thereto.
When a lens is to be removed, the nut is turned on the bolt enough to loosen the plate from the lens to the extent required for its withdrawal; and, after another lens has been inserted into the eyecup, the plate is tightened to lock position.
Two of the eyecups of the invention may be connected as a pair of goggles in any suitable manner. For example, as seen in Fig. 2, they may be connected by a bridge band 4|, which passes around the end frame member I6; or, as seen in Fig. l1, a headed bridge member 42 may be disposed through an opening 43 in the nasal end of each eyecup.
1. A goggle comprising a frame of substantially parallel side members connected by end members, opposite ilanges on the inside of said side members, lingers extending inwardly on said side members, a stop at one end of said frame and there being an opening in the other end thereof, a lens slidable between said anges and fingers to said stop, a latch, an elongated ilexible member disposed through said opening, connected to said latch, and normally holding the latter locked with respect to said lens.
2. A goggle comprising a frame of substantially parallel side members connected by end members, opposite anges on the inside of said side members, ngers extending inwardly on said side members, a lens slidable into and out of said frame between said flanges and ngers, and releasable means to hold said lens in said frame, there being Ventilating vents between said ngers in said side members and flanges adjacent to the edge and under marginal surface of said lens.
3.

4. A goggle comprising a frame of substantially parallel side members connected by end members, spaced anges on the inside of said side members, fingers extending inwardly on said side members over the spaces between said flanges, a lens slidable to and from normal position between said fianges and fingers, and releasable means to hold said lens in normal position, there being Ventilating channels extending inwardly in the walls of said side members between said fingers past edges of said lens'y and in said flanges under the marginal surface of said lens.
.5. A goggle comprising a frame, a lens slidable into and out of said frame, a latch bodily movable substantially in the same plane. as said lens toward and from an edge thereof, and an elongated ilexible article connected with said latch and operable to pull the latter toward and to hold it against said edge.
