Patented Niel. 18, 1930 UNITED STATES PATENT OFFICE EARLE J. R. BEAT TEY, OF EDGEWOOD. RHODE ISLAND, ASSIGNOR T0 UNIVERSAL OPTI CAL CORPORATION, OEPROVIDENGE, RHODE ISLAND, Av CORPORATION OF RHODE ISLAND OPHTHALMIC MOUNTING Application filed March 13, 1929. Serial No. 346,626.
This invention relates to an ophthalmic mounting of. the type having two non-metallic lens frames secured together by a metallic bridge; and has for its object to provide a secure means for connecting the bridge to the non-metallic frames.
A further object of the invention is the roviding of pins secured. to the metallic ridge and extending thru the non-metallic frame, the ends of which pins have an enlarged engaging surface extending over the non-metallic frame to prevent their withdrawal and thus hold the parts in assembled relation. 7
With these and other objects in View, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims. v
In the accompanying drawings:
Fig. 1 is a'face view of an ophthalmic mounting partially in section to illustrate the means of holding the bridge and nonmetallic frame assembled.
a Fig. 2 is a face view of the metallic bridge.
Fig. 3 is a face view partially in section of one of the lens frames.
Fig. 4 is an edge view of the bridge.
Fig. 5 is an enlarged fragmentary view partly in section showing the connection of the bridge to the lens frame.
Fig. 6 is a sectional view on Fig. 1. V
Fig. 7 is afragmentary view of a portion of the bridge showing in section a modified form of rivet.
Fig. 8 is a section taken through the split of the approved form of rivet.
In the usual construction of securing together non-metallic frames by a metallic bridge the rivets which are used are secured to the bridge and extend thru the non-metallic frame and are spun over to form an enlarged head and in spite of the size of the head which it has been found practical to form on the end of the rivet by spinning, the connection becomes loose and will not hold in the non-metallic frame; and in order to form a more secure attachment for holding these together I have provided a longer rivet and line 66 of ening or detachment; and the following is a detailed description of the present embodiment of the invention, illustrating the preferred means by which these advantageous results may be accomplished:
l/Vith reference 'to the drawings,'10 designates one non-metallic lens frame or rim and 11 the other frame or rim, both of which are formed of zylonite, celluloid, shell orother suitable similar substance with end pieces 12 for hinging a temple thereto where desired.
The bridge 13 extends across between the frames 10 and 11 and may be in any desired relative location with reference to the center line between the lens rims and is provided with arms 14 extending along the outer surfaces in contact with each of the frames 10 and 11.
Solid tubular rivets or pins 15 are soldered to the arms 14 in the desired number and extend thru the frames 10 and 11 into the grooves 16 formed therein for the mounting of the eyeglass. Each of these rivets or pins is drilled in 1ts end to remove a portion of the stock and then the riveting portion and form a hole 17 after which the drilled endv of the rivet is split, as illustrated in Fig. 2, to provide portions 18 and 19 which may be separated and folded over the inner surface of the frame adjacent the point thru which the rivet extends and forced into the material of the frame. so that the spread portions of the rivet will lie substantially flush with the surface of the groove 16 and not interfere with the mounting of the eyeglass therein.
In the modification shown in Fig. 7, I have illustrated the rivet 20 as being tubular throughout its length which is soldered to the arm of the bridge as at 21 and is split as at 22 a portion of its length to provide portions 23 and 24 to be spread over the inner surface of the frame as has been previously described to secure it thereto. In this latter embodiment of the invention, it is of course unnecessary to drill the end of the rivet as was pre viously in connection with. the solid rivet 15.
The foregoing description is directed solel v towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible,
the invention being defined and limited only by the terms of the appended claims.
I claim:
1. In an ophthalmic mounting, a pair of non-metallic lens frames, a metal brid e member having arms extending along sald frames, a rivet secured to said arm and extending thru said frame, the end of said rivet being tubular and split with portions extending in opposite directions over the inner surface of said frame.
2. In an ophthalmic mounting, a pair of non-metallic lens frames having a grooved inner surface for the mounting of the eyeglasses therein, a metallic bridge joining said frames and having arms extending along and in contact with the outer" surfaces of said frames for a substantial length, rivets secured to each of said arms in spaced relation and extending thru said frames, the ends of said rivets being tubular and split with the split portions oppositely spread and bent over the frame into the groove thereof.
3. In an ophthalmic mounting, a pair of non-metallic lens frames each having a grooved inner surface for the mounting of the eyeglasses therein, a metallic bridge joining saidframes and having arms extending along and in contact with the outer surfaces of said frames for a substantial length, rivets secured to said arms and extending thrusaid frames, the ends of said rivets being tubular and'split with the split portions oppositely spread and bent over the frame in the groove thereof.
4. In an ophthalmic mounting a pair of non-metallic lens frames having a grooved inner surface for the mounting of the eyeglasses therein, a metallic bridge joining said frames and having arms extending along an'din contact with the outer surfaces of said frames for a substantial length, solid rivets secured to said arms and extending thru said frames', the ends of said rivets being tubular and split with the split ortions oppositely spread and bent over the rame in the groove thereof and pressed onto the frame to lie substantially flush with the inner grooved surface of the frame.
In testimony whereof I afiix my signature.
