PHTHALMIC FRAME.

Application filed August 11, 1922.

To (LU 1071077@ 'if may cou-(fern,

Be it: known that l. WILLiAM J. lVRluHToX, a. citizen ol the` liuited States, residing at Southbridge.in the county of Torce'ster and State of Massachusetts, have invented certain new and useful lmprovements in Ophthalmic Frames, of which the following is a specification.

This invention relates to new and useful improvements in ophthalmic Inountings and n.ore lntrticularly to the construction of thel lens receiving frames. 4 Various ways have been attempted for mounting a non-metallic rim upon a metallic rim in such a manner as to retain the non-metallic rim imposition and have the same hold its position under atmospheric changes and also under the usual wear and tear onthe mounting and to apply this nonmetallio covering in, an inexpensive manner. lThe main object of my invention is to fit the metallic frame of an ophthalmic mount-- ing with a non-metallic outer shell which will be neat in its appearance when fixed in position and which will withstand various atmospheriil changes and the usual wear and tear upon a mounting of this character.

Another object of my invention is the a-pplicagtion of a` non-metallic riml to the metallic` lens rim of `an ophthalmic mounting and in addition placing a coatingpof liquid cement `over the edges of the non-metallic rim so as to ret-ain these edges in `position and prevent them from moving away from the edges of the metallic rim as has been found to be the case under various atmospheric changes. r

A still further object Aof the invention is the provision of an ophthalmic mounting including a metallic rim and an outer non- `1netallic rim applied to the metallic. rim having its longitudinal edges fitted close to the metalic rim at the outer edge of the lens receiving groove and then apply a coating of liquid transparent cement, said coating to cover the line of joinder between the non-metallic and metallic rims and extend over onto the non-metallic part, the central portion of the cementitious coating extending down into the lens receiving groove and forming a binder between the two side edges of the' non-metallic rim whereby toretai the'min their proper positions.

Serial No. 581,095.

lith the above and other objects in view the invention consists in the novel features of construction, the combination and arrangement of parts herein-after more fully set forth, pointed out in the claims and shown in the accompanying drawings, in which Figure I is a front elevation of an ophthalmic mounting constructed Ain accordance with my invention.

Figure Il is a transverse sectional view taken on the line II-ll of Figure I.

Figure IH is a detail perspective of a. portion of the stock used to form the non-metallic rim showing the same in its normal condition.

Figure lV is a detail perspective illustrating the flat stock rolled to conform to the exterior of the metal eye wire. l

Figure V is a transverse sectional view showing the non-metallic material in position.

Figure VI is a similar view showing how the edges of non-metallic material 'are -forced inwardly onto the metallic inner rim. i

Figure VII is a transverse sectional view showing the application of the liquid cement, and

Figure VH is a transverse sectional view of the non-metallic shell` the metal rim being removed.

Referring now more particularly to the drawings it will be noted that in Figure I the numeral l indicates the'usual lens receiv- -ing f1'ames,suitably connected by means of the nose bridge 2 and further provided with temple members 3 whereby the mounting may be securely positioned upon the face oi the wearer.

ln carrying out my invention ll prefer to" utilize the stock in the Hat normal condition .as illustrated in Figure III, the strips 4 of the stock being cut to the desired length and width and then rolled to a semi-circle as at 5 or rolled to the desired shape according to the shape of the metallic rim upon which the coating is to be applied. The non-metallic rim 6 is fitted in position over the peri her of the metallic rim as shown in Figure an' the edges of the same pressed inwardly onto the metallic frame by means of a. roller 7 having grooved runways 8, the edges of the non-metallic casing fitting into the runways 8 and bymoving the roller .7 over the edges ofthe casing while in a lheated state the edges thereof will be forced inwardly onto the eye Wire land into their proper po sitions. t

- In Figure VH i have illustrated ythe application of a transparent liquid cement, said cement being placed within the lens receiving :groove of the rims l as shown, the groove being 4filled level with the side edges and then by placing the frame ontol a. mould or the like thecementitious material 9 will be spread lover thc joinder between the nonmetallic and metallic rim and after hardening forms a substantial binder between the edges of the .trim and as this material is of transparent lquid zyl or other similar inaterial so that fter the form liars been lplaced Within the rim and adjustedv to the proper size, the plastic cement 7 will be forced outgologie@ What l Claim is 1. An ophthalmic mounting including a metallic roove'c'beye wire, 'a non-metallic covering or said eye wire having its edges terminating at the outer edges of the groove `and ay transparent cementitious material forming a coating for the metallic material and connected with the edges of the nonmetallic covering.-

2. An ophthalmic mounting including a non-metallic covering having its edges a1'- ranged in spaced relation. and a transparentcementltlous materlal forming a jolnder between said edges as and for the purpose set forth. y

'ille process of forming a non-metallic coating for ophthalmic eye Wires consisting of .rolling a piece of iiat stock to a substantially semi-circular shape7 fitting the Same over Ythe metallic eye wire forcing the edges of the non-metallic covering onto the eye wire and applying a coating ot transparent rementitious material thereto to form a l indcr between the edges 'of the non-metallic cov erlng to retain the same in position on the eye wire.

4. An ophthalmic mounting including grooved metallic \vires,n`on metallic cas' ings fitted over said eye Wires with the edges thereof disposed upon opposite sides of the groove and a transparent cementitious mate rial 'forminga binder between the edges of the non-metallic casing to retain the same in position upon the eye Wire.
