'Ihe present invention relates" particularly to an] ophthalmic m ounting embodying a pair of lens rims 5 each having a. continuous inner bev- ,elled groove 6 adapted to receive the peripheral bevelled edge, lof the 'lens 8.

t The lens rims 5 are provided on the nasal sides thereof with lugs 9" having rearwardly extending, nose bearing members In. The said rims 5am "connectedby a bridge member having a central arohflportion ll "and dependi'ng'side portions I2 secured to attachment, platesf l3 asby soldering, welding or the like. The attachment plates are secured to the lugs 9 by suitable connecting means 14., Such as pins, screws or the like anchored to said plates and extending Within the, material of the body of The mounting is provided with relatively long and slender temple supports l5 preferably formed of metal so as topermit adjustment. The long and slender temple supports l5' are anchored at?! -to the bridge. and attachment plate assemblyfas ,by soldering, welding or-the like, and jarefdimensioned and proportioned so thereof, as illustrated 'in the drawing.) The said long and slender temple supports progress ontwardlyto' rearware y extending end portions I 161 to which temples I! are 'pivotally attached as illustrated .at la.

t Spaced Iin'wardly from said rearwardly extending portions 16,, as illustrated in Figs. 2 and 3, "there is "provided'clip or an.-

means I9 is bent to fit the bevelled edge 1 of the lens and to lie within the inner bevelled groove 6 of the rim. The said clip or anchor means is preferably formed of relatively thin sheet material and has an intermediate portion 22 which is adjustable by bending to control the space 23 between the support and rim. The intermediate portion, in addition to being adjustable, can be formed to difierent lengths so as to afford additional control of the spaced relation of the long and slender temple support I and the rim 5. As shown in Fig. 2, the clip or anchor means I9 is formed with a relatively wide end portion 2| fitting between the rim and lens and tapers rearwardly, as illustrated at 24, to areduced end portion which is attached to the support l5. support l5 may be raised or lowered relative to the rim by bending the clip or anchor-means IS with such bending affording adjustment to control the spaced relation of the temple support and rim. The said clip or anchor means I9 is adapted to retain the temple supports in proper adjusted relation with the rims during the use of the mounting and affords means for counteracting stresses and strains incident to the manipulation of the temples in donning or removing the spectacles as well as during wear thereof. The purpose of the long and slender temple supports is to avoid having conspicuous end-piece means for the temples adjacent the outer temporal sides of the rims and the clip or anchor means set forth above is in strict accord with the immediate'concept of such a construction in that said clip. or anchor means is substantially invisible when in position of use.

An additional purpose of providing long and slender temple supports in a construction of the character described is to provide a strut-like sup- ,port between the temples and the bridge memgnitrate or the like which have expandable and contractabl'le characteristics whereby the rims It is to be understood that'saidthe expansion and contraction of the rims with no danger of having parts break out as might be the case if the clip or anchor means were attached to the rim. In this manner, the entire rim is free to expand or contract.

In Fig. 4 there is illustrated a a slight modiwrapped around and clamped to the temple support l5. Inthis construction, the clip may be may be formed continuous and be placed on the lenses by initially forming the lens rims larger than the diameter of the lenses and thereafter causing the said rims to shrink into binding relation with the lenses.

tached to the rims, would be a hindrance to the t expanding and contracting of. the rims. This "difficulty is overcome in the present invention by providing clip or anchor means of the type which is normally separate from the rims and which is adapted to be rigidly held in position by placing a portion of said means between the lens and rim and thereafter causing the rim to contract thereon, with the contracting function of the rim serving to retain the parts in rigid and positive relation with each other. Itis quite apparent that such a construction readily permits free to slide longitudinally of the temple support whereby it may be placed at any desired 10- cation relative to the rim to retain the parts in proper aligned relation with each other whenthe end 26 of the clip or anchor means is secured betweenthe rim and lens.

In assembling the mounting the lenses are first edged to the proper size and shape and to a suitable bevelled edge to fit within the V-shaped groove internally of the rims. The rims 5 may be initially formed. to a diameter which will permit the lenses to be placed internally thereof or the said rims may be stretched an amount sufl'icient to "receive the lenses. This is accomplished by heating the rims and then expanding them by forcing them over a suitable tapered mandrel of the shape desired of the rims. The long and slender temple supportslare adjusted to follow the upper contour shape of the rims and to lie in the rear thereof. .The clip or anchor means of the type illustrated in either of Figures 3 and 4 is positioned between the lens and rim .and the rim is thereafter allowed to contract on the lens. Such contraction may be hastened by subjecting the rim to a cooling treatment or it may be permitted to contract at room temperature depending upon the material used in forming the rim. The bridge member is adjusted to position the rims in proper spaced relation with each other according to the interpupillary distance between the eyes of the individual and to properl fit the nose bearing pads to the nose of the wearer. The said bridge member, when properly'adjusted, supports the rim members and lenses in. proper aligned relation with each other. In'such a construction the long and slender temple supports have a. two-point support; namely, at the end 21 which is attached to the bridge and attachment plate assembly and at the location of the clip or anchor means 19. In the final assembly it is quite apparent that the portion of the clip or anchor means lying between the lens and rim will be substantially invisible.

From theforegoing description it will be seen that simple, efficient and economical means have been provided for accomplishing all of the objects and advantages of the invention.

Having described my invention, I claim:

1. An ophthalmic mounting comprising a pair of continuous lens rims of-expandable material having. internal bevelled groovesadapted to receive and support lenses having peripheral bevelled edges in combination with a bridge member for supporting said lens rims in spaced relation with each other, long and slender, temple supports each secured 'to the mounting at a point adjacent the bridge member and shaped to follow substantially the upper contour shape of the lens rims and having outer temple supporting ends to which temples are pivotally' attached and relatively narrow clip members of relatively flat ma.-

inner ends Secured adjacent the bridge and being shaped substantially to follow the upper contour shape of the rims and terminating in temple pivterial each having an end connected with one of said long and slender temple supports and each having a portion extending forwardly of said temple support and terminating in an end portion shaped to substantially conform to and to lie between the bevelled edge of the lens and the inner bevelled groove of the rim and in non-connected relation with the rim whereby the rim is free to with one of the long and slender templesupports and having a portion adaptedto' lie'between the lens and rim in disconnected relation with said lens and rim whereby the rim will be freeto be expanded and to contract and will firmly retain the clip member in position when the said lens and rim are in related position of use.

3. In an ophthalmic mounting the combination of a pair of beveled edged lenses, continuous undivided lens rims of expandable material each having an internal bevelled groove fitted to the lenses, bridge means connecting said lens'rims, long' and slender temple supports having their otal connections and relatively narrow clip members formed of normally fiat relatively thin sheet material each having an adjustable portion connected to along andslender temple support to vary the distance between the rim and temple support and a portion in non-connected relation with the rim but shaped substantially to the shape of the bevelled edge of the lens and secured be'- tween the edge of the lens and the rim by caus ing the material of the rim to contract and intimately fit the contour of the lens.

4. In an ophthalmic mounting the combination of a pair of lenses, continuous undivided expand able lens rimsya bridge member supporting said rims inspaced relation with each other and long and slender temple supports shaped to follow the upper contour shape of the rims and each secured to the mounting at a point adjacent the bridge member, clip means comprising a plurality of clip members, each having a portion'connected with one of the long and slender temple supports and having a portion lying between the lens and the rim in-disconnected relation with said lens and rim whereby the rim, when being assembled with the lens, will be free to be expanded and to contract and will firmly retain the clip .member in position when the said lenses and rims are in said related position of use.
