IMPROVEMENT IN EYEGLASSES.

Specification forming part of Letters Patent No. [85,342, dated December 12, 1876; application filed July 24, 1876.

To all whom it may concern:

Be it known that I, GEORGE MEIGS, of Reading, Pennsylvania, have invented cer tain Improvements in Eyeglasses, of which the following is a specification The object of my invention is to effect a saving of time, cost, and labor in the manufacture of eyeglasses; and this object I attain in the manner which I will now proceed to describe, reference being had to the accompanying drawing, in \vhicl1 Figure 1 is an enlarged view of a pair of eyeglasses, showing the ordinary method of constructingthe same; Fig. 2, an enlarged View illustrating my improvement, and Figs. 3 and 4 views illustrating different steps in the manufacture.

In eyeglasses as usually constructed, a stud, a,is secured to the inner portion of each frame I), and to these studs are then fastened the opposite ends of the spring d, and the upper ends of the curved nose-pieces e, the lower ends of the latter bearing against the frames, as in Fig. I. This mode of manufacture is objectionable, partly on account of the cost of the studs and the inconvenience of applying the same, and partly because they must be attached to the solid portion of the frame I), thus necessitating elaborate and expensive screw-joints at the handle A and catch B, as shown in Fig.1.

I obviate the objection in the following manner: I first stamp from a piece of sheet metal a strip of the form shown in Fig. 3, having a liead,f, a neck, g, ears 1' i, and a shank, m, the latter being serrated or roughened on the face in the same manner as an ordinary nosepiece. If desired, the holes for the fasteningscrews may also be formed by this operation. The shank m is then bent round, the head f turned down, and the cars it turned up, as shown in Fig. 4, when the strip is in condition for attachment to the spring d and frame I). To effectthis attachment, the head fis first secured to one end of the Wire which forms the frame I), and a strip, 19, is secured to the opposite end of the same, the two being then secured together by a set-screw or other suitable means. The end of the nose-piecem is then bent round until it bears against the frame b, and the end of the spring is fitted between the ears 6 i, and secured by a setscrew.

By this means the solid portion of the frame I) is brought upon the outside, so that a handle, A, and catch B, of a simple charactersuch as may be easily stamped from a sheetmetal plate-can be secured to the same by soldering or brazing, as shown in Fig. 2.

Irrespective of the saving of time and labor effected by my invention, the device itself is strong, neat, and durable, and can be manufactured at a cost but little, if any, greater than the ordinary nose-piece m.

In some cases the ears iimay be dispensed with, and the lateral steadiness of the spring at insured by the securing-screw alone.

I do not desire to claim eyeglasses the glassframes of which have their joints where they are connected to the bridge-spring but I claim as my invention The combination, in a pair of eyeglasses, of the spring (1, and the frame I), and its stripp, with a nose-piece having a shank, m, a neck, g, for attachment to the end of the spring, and a head,f, for attachment tothe frameb and its stripp, all substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE W. MEIGS.
