NEW JERSEY, ASSIGNORS TO NEW JERSEY OPTICAL (10., 0F NEWARK, NEW JERSEY, A CORPORATION OF new JERSEY.

To all whom it may concern:

Be it known that e, EDGAR R. DURGIN and WAYNE .S. SEARLES, citizens of the United States, and residents of Newark, county of Essex, State of New Jersey, have invented certain new and useful Improvements in Eyeglass and Spectacle Mountings, of which the following is a'specification.

a Our invention has for its general object to provide an improved construction of means whereby the lugs to which the temple wires are secured and also the opposite ends of the bridges of eyeglasses and spectacles may be more efliciently and economically attached to the lens rims.

A further and more specific object of our invention is to provide means whereby such parts may be more securely attached and fastened to lens rims, particularly nonmetallic rims, than heretofore, as far as We are aware, has been practicable.

Our invention also has for one of its ob.- jects to provide an improved construction of fastening or securing means which may beattached or fastened to non-metallic rims without injuring the same or biting into thematerial thereof in a manner to impair the strength and durability thereof.

Other objects and advantages of our invention will be referred to in the detailed description thereof which follows or will be apparent from such description.

In order that our invention may be more readily understood and .its purposes and advantages more fully appreciated reference should be had to the accompanying drawing in which We have illustrated one form of.

a convenient embodiment of our invention. It will be understood, however, that changes in the details of construction may be made Within the scope of the claims without departing from our invention.

In the drawings :Figure 1 is a s de elevation of a lens rim provided with a device embodying our invention; Fig. 2 is a transverse section taken on the line 2-2 of Fig. 1 and showing the inner edge of said device attached to a lens rim; Fig. 3 is a transverse sectional view, enlarged, taken on the line 3- 3 of Figs. 2 and 4; Fig. 4 is a view similar to thatshown in. Fig. 2 but With the parts considerably enlarged; Fig. 5 1s a sectional view taken on the line 55 of Specification of Letters Patent.

Patented Feb. e2, 1913: Serial No. 68,989.

Fig. 4; and Fig. 6 is a view of the parts entering into the construction of our invention, said parts being separate from. each other and ready to be assembled.

In the construction as illustrated we have shown but a single'lens rim and a single attaching or fastening device embodying our invention but it will be. understood that one of these fastening devicesmay be employed for each temple wire and also that two of such fastening devices may be employed in connection with each bridge or spring.

eferring to the drawings, a lens rim of non-metallic material having to receive the edge of a lens and 2 designates an elongated part of sheet metal bent and adapted to embrace a portion of the rim as illustrated. The said part 2 is curved longitudinally so as to conform to the peripheral curvature of the lens frame. Such curvature is best illustrated in Figs. 1 and 5.

In transverse the device 2 is substantially of U-shape as illustrated in Fig. 3. The inner edges of the part 2 are provided with undercut n0tches3 adapted to receive the projecting tongues 4 upon the opposite edges of a cooperating complemental strip 5. The part upon the lens rim the plate 5 is placed in position intermediate the inner edges of the part or member 2 with the projecting tongues 4 in engagement with the notches 3. After having been thus positioned the parts '2 and 5 are acted upon by a proper tool to bend the inner edges of the part 2 upon opposite sides of the notches 3 inwardly and slightly inner edges of the rim upon opposite sides of the groove 1. The strip 5 is also bent or curved both longitw.v dinally and transversely so as to cause it to conform to the groove 1 upon the inner side of the rim. After the parts 2 and 5 have been pressed or otherwise caused to conform to andclamp the rim at the point Where they surround thesame, the tongues 4 extend laterally in directions transversely of the plane of the rim and are situated in the said notches 3 in substantial alinement with the inwardly bent edges of the part 2. In the completed'st ructure the edges of the device 2 intermediate the notches 3 are in abut.,

1 designates section the body portion of intermediate and outside of the projecting tongues 4. The preferred relation of these abutting edges is shown at 10 in Fig. 3 of the drawing. It should be understood, however, that the relation of these edges may be changed without departing from the spirit and scope of our invention.

11 designates a stud or projection secured in any manner, as by soldering, to the outer 'curved edge of the member 2. The stud 11 of the rims of a pair of eyeglasses.

By the employment of our construction it will be observed that a portion of the rim is completely embraced or surrounded by means of the part 2 and its cooperating and complemental strip or part These parts cooperate to form in effect a sleeve within which a portion of the eyeglass rim is held, such sleeve conforming to the shape of the particular portion of the rim where it is situated. By thus providing means for completely embracing the rim we are enabled to avoid the necessity of providing prongs or 'other parts which must be caused to bite into or become embedded in the material of the lens rim in order that the same may be securely fastened or attached thereto. It is apparent, therefore, that our invention constitutes a valuable improvement in that it prevents injury in any way to or impairment of the eyeglass or spectacle rim.

We claim v 1.
