Claims.

This invention relates to improvements in ophthalmic mountings and has for one of its objects to provide an improved mounting of simple and practical construction wherein a supporting frame 5 and lens rims of diiferent materials are joined together by novel arrangement of parts.

A further object is to form a supporting frame with rim portions having straps at the ends thereof which engage around marginal edges of the rims of the mounting to secure the parts together, with each of said rim portions further having a retaining member engageable over an edge of its associated rim with a part of said member countersunk in said edge.

The above and other objects will appear more clearly from the following detailed description when taken in connection with the accompanying drawing which illustrates a preferred embodiment of the inventive idea.

In the drawing:-

Figure 1 is a front elevation of an ophthalmic mounting illustrating the present invention.

Figure 2 is a top plan view thereof.

Figure 3 is a perspective view of the parts of the mounting separated from each other.

Figure 4 is a section on the line He! Fig. 1.

Figure 5 is a section on the line 5-4 of Fig. 1, and,

Figure 6 is a section on the line 6-6 of Fig. 1.

The present construction is especially, although not necessarily, adapted to an ophthalmic mounting in which the supporting frame, generally indicated by the numeral I, and the lens rims l are made of different materials, such as metal and Celluloid, respectively.

As illustrated, each of the lens rims 8 is provided at its upper edge with a longitudinally extending recess or groove 8 which may be of any desired length and the purpose of which will presently appear. Adjacent the upper ends of the inner and outer marginal side edges of the rim 8 where the width of the rim is usually enlarged as indicated at it and II, said edges are provided with notches i2 and I3, respectively.

The metallic frame I is provided with any conventional form of nose bridge i4, and extending laterally from opposite sides of said bridge are the rim portions l5 curved generally to conform to the contour of the upper edges of the associated rims t. At the inner and outer ends of each of the rim portions i S the same are provided with end straps it and I! each bent upon itself into angular form so that the opposed parts thereof will engage the front and back of the associated rim 8. with the 55 intermediate portions of the straps it and I1 disposed, respectively, in the notches l2 and ll of said rim. When so positioned, the front of the rim portion I! will extend along the front face of the rim 8 and the depth of said notches i2 and I3 is such that the intermediate portions of said 5 straps will be flush with the outer marginal edges of the rim. Said straps thus assist in supporting the rims l in position and, if desired, rivets or other suitable fasteners it may be extended through the opposed portions of said straps and 10 also through the rims.

As an additional means for retaining the rims in fixed position upon the frame, each rim portion I! of the latter is provided with a retaining member I! in the form of a rearwardly directed flange 15 extending from the upper edge of the rim portion and partially over the upper edge of the rim 8, as best shown in Fig. 6. At the inner edge of said flange I! the same is provided with an inturned edge which, when the rim 8 is in position, projects into and fits snugly within the recess 9 of said rim. This interengagement of the edge 20 in said recess further aids in securing the rim to the frame and prevents any possible lateral spreading of said parts. When the flange I9 is elongated so as to be coextensive with the rim portion i5 said flange will extend over and cover the upper forward edge of the rim 8 and thus prevent any possibility of accumulation of dust or other foreign particles between the abutting surfaces of the -rim so I and portion i5.

What is claimed is:

1. In an ophthalmic mounting, lens rims each having a longitudinally extending recess formed in the upper portion of the peripheral edge thereof, and a supporting frame for said rims provided with rim portions engaging the front faces of said rims and each of said portions having a rearwardly directed flange extending only partially over the upper peripheral edge of its associated o rim and provided with an intumed edge engaging in the peripheral recess of said rim.

2. In an ophthalmic mounting, lens rims having opposed notches formed in the marginal side edges thereof, and each further having a recess in 5 its upper edge, and a frame including rim portions for supporting said rims, and each having straps at its ends extending around the marginal edges of the associated rim and engaging in said notches therein, said rim portions each further provided with a retaining member extending over the upper edge of its rim and in the recess therein.

3. In an ophthalmic mounting, lens rims each having a longitudinally extending recess formed in the upper edge thereof, and further having 5 opposed notches formed in its marginal edges, and a supporting frame for said rims including rim portions each engaging the front face or its associated rim and having a rearwardiy directed angular flange extending over the upper edge of said rim and into said recess, each of said rim portions further having angular straps at its ends extending around said edges and engaged in said notches.

4. In an ophthalmic mounting, lens rimseach having a recess in its upper peripheral edge, and a frame including rim portions extending only along the upper edges of said rims with each rim portion bent at each end to form an angular strap including opposed portions engageable on opposite sides of an associated rim and further including an intermediate portion straddling the peripheral edge of said rim, a bridge attached to said intermediate portion at the inner end of each of said rim portions, and a flange on each rim portion tuting a strap for receiving one of said supported 10 members and engaging on opposite sides thereof,

an angularly extending retaining flange formed on each rim portion and having an inturned edge for engagement in a recess provided in the peripheral edge of the associated supported member, and a bridge connecting the straps at adjacent ends of said rim portions.

VINCENT TANASSO.
