SPECTACLE MOUNTING Original Filed Dec, 12, 1938 JNVENTOK @0265 .Z Sweeney A TTORNEY S.

Reissued Sept. 17, 1940 UNITED STATES PATENT OFFIC SPECTACLE MOUNTING James A. Sweeney, Providence, R. I., assignor to Universal Optical Corporation, a corporation of Rhode Island Original N6. 2,194,776, dated March .26, 1940, Serial No. 245,092, December 12, 1938.

Application for This invention relates to a spectacle, more particularly to the mounting of the temple of the spectacle, and has for one'of its objects to provide a .single point of attachment for the bridge and the temple mounting in order that the assembly operations may be reduced to a minimum.

Another object of the invention is to provide a mounting for the temple support member which will be simple in assembly and require no sharp bending operations of the support member.

Another object of the invention is to provide an attachment or anchor for the temple support member on the nose pad support arm and yet provide a mounting which will not be disturbed by adjustment of the nose pad.

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.

In the accompanying drawing:

In constructions of this general character, it

has heretofore been necessary to anchor the temp le support member on a strap which engages the lens and to mount the pad support arm completely independent thereof, inasmuch as the pad support arm is adjusted through considerable extent to fit the faces of different wearers. This construction also required the sharp bending of the temple support member at its anchored end for the correct positioning thereof and in order to avoid such an arrangement, I have stiffened the pad support arm at its point of connection to the bridge or strap making the remainder of the arm relatively bendable so that any adjustment will occur beyond the stiffened portion leaving the stiffened portion fixed relatively to the lens and I have mounted the temple support member on the stiffened portion which affords a very simple assembly operation and positions the temple support member the distance desired rearwardly of the lens without any sharp bending to dispose a portion of it rearwardly at this point of connection, and the following is a more detailed description of the present embodiment of this invention, illustrating the preferred means by which these advantageous results may be accomplished:

With reference to the drawing, l0, l0 designates the lenses and II a bridge spanning the distance between the lenses and holding them a desired distance apart. Each strap l2 consists of a pair of arms l3 and I4 connected together by a shoe l5 which has a hole l6 therein utilized for mounting the strap upon another part. The nasal edge of the lens extends into the strap between the arms !3 and l 4 and is there secured by a suitable screw I'I passing through the arms and lens between them.

A pad support arm l8 has a relatively widened portion is to cause the same to be relatively stiff and a narrower, thinner portion20 which in comparison is relatively bendable. This stiffened portion I9 is reduced as at 2| for the reception of the shoe which is attached thereto. A dowel pin fitting in and extending from. the opening l6 also fits into a hole 22 in this reduced portion of the arm for providing a simple manner of locating the parts to be soldered and also enables a subsequent soldering of the bridge II as at H to these previously soldered parts. This manner of connection enables the second soldering which necessarily must be at a temperatureless than the fusion of the first soldering to be more readily and easily accomplished. The fit of the reduced portion 2| with the shoe I5 of the strap is such that the dowel pin 23 may be riveted to hold the parts in position if necessary. The end 24 of the nose pad support arm 3 is twisted and provides a good support for the nose pad 25 on the end of the arm.

The temple supporting member 26 is of wire and is bent to conform to the contour of the lens and extends just back of the lens following this contour of the lens. Its nasal or anchoring end portion 21 is connected to the stiffened portion of the nose pad support arm I8 by recessing the thicker temple support member as at 28 so as to receive this relatively thinner stiffened portion IQ of the pad support arm, the recess being of a depth equal to the thickness of the pad support arm to make a smooth surface at the junction. The temple support member is located the desired distance rearwardly from the lens along the support arm so that it may extend upwardly in substantially a single plane and then follow the contour of the lens both as to peripheral shape and as to curvature which may mean a bending in two different planes. The support member terminates in a position to support the temple 30 in a position above the sidewise vision of the wearer. The temple end of this support member 3| is enlarged as at 32 and slotted as at 33 forming ears 34 and 35 having registering openings 36. The flattened eye 31 of the temple is inserted between these ears and a screw 38 passes through the registering openings and is threaded into the ear 35 to provide a pivotal mounting for the temple.

In some cases instead of recessing the temple supporting member 26 in the form shown in Fig. '7 I may cut out a. portion as at 39 to extend to the end ofthe member as in Fig. 10 and also extend the reduced portion 40 of the pad support arm so that these two parts may fit together as at 4!, the length of this recess 40 being suflicient to accommodate the strap such as shown in Fig. 4.

In both of these arrangements illustrated, the temple support member is secured to a stiffened portion IQ of the pad support arm forming a rigid anchor for this end of the temple support member and maintaining it in fixed position relative to the lens even though the pad support .arms are bent for accommodation of the pads to the faces of different wearers.

The foregoing description is directed solely 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.
