I., application inea' Jane ai, isos. serial No; 503,850.

Be it known that I, Joan Crimini' Wenns,

' a citizen of the United States, anda resident `ing is a specification.

My' invention relates to eyeglasses of the kind in whichpivoted spring pressed nose 'clamps are provided in conjunction with fin` ger pieces for operating said(k clamps. op In l:eyeglass constructions as aforesaid it is usual `to-malre the noseclamp and, nger piece-integral with one another, the finger piece projecting 'forward from the pivotaly point and the nose clamp rearward from the same.

' Tlic object of ny present. invention is to l r ger grips J on aeach lens are grasped beprovide a finger `piece independent ,of but connected with the pivoted nose clamp whereby said nose clamp may be operated;

such .a construction enables me to select the extent so that I am able to make it less cone icuous and, in many cases, more attractive t an when made in the usual manner. "My invention also permits the combining" or anyodesired nose clamp with any preferred design of finger. piece. Y,

Finger pieces accordinggto my invention herewith may have a straightline motion as` contrasted with'the vmovement in circular arc which obtains with the integrally united pivoted form of nose clamp and finger piece. In the drawings accompanying, which are made a part-ot this specification; I have illustrated various modifications ofmy iinroved inger piece construction, Figure l going an enlar ed front elevation of' a preferrd form otgvmy invention; Fig. 2 being a plan view of Fig. l; Fig.' 3 being a plan, similar to Fig. 2, of an alternative form or" my invention, and Fie'. 4C a plan, also similar to Fig. 2, showing still a third form of .my invention.- Figs. f3 and 4 each show only one of the nose clampingsystems of the eyeygiasses, the remainder of each plan being broken away as being to save oom.

Referring to the gures, A, A are the nose only a duplication und clamps oi usual form, having each a lever B,

itself pivoted at C to the bridge il n. spring E is supported aoove the lever B. upon thek pivot screw C and has one end hooked about said lever and the other. end

parallel with the plane of the lens.

engaging the lens strap E; the spring therefore acts not only to press the nose clamping system down against thesupporting'bridge but alsqf' te'rnaintain a constant inward pres' sure upon the nose clamps. `Att/ached to or `forming a part of each lenselip G anden the front side thereof is a sleeve H, the axis genion.

of which is substantially horizontal and In veach of these sleeves and having a sliding t therewitlris a short plunger I terminating' on its outer end in a finger grip J, and-at its inner end in an upward bendY l which engages a hole L in the tnrwardlyextending lportion olf/'lever B. Spring E,`as it presses the nose clamps inwardly will, therefore,'

press rods I and attached linger gripsJ outwardly. L i a [d To place the lenses on the nose, the tint'ween thumb and forefinger respectively and pressed inwardly against the resistance of.-

the two springs E. The nose. clamps will..A

thus be opened when the eyeglasses may be lslipped upon the noseand allowed to clamp thereon. y

In theconstruction showuby Fig. 3 the spring `E of previous figures is now placedv inside the sleeve as E', the sleeve being madeA `larger for this purposeya shoulder L itorined upon the plunger keeps the spring 1n place. The pperation of the eyeglasses and the adjustment to the nose is exactly the same as in the case ofFigsl l and 2.

,F ig. iisthqe same as Fig. 3 except that the grip J2 of the finger piece is attached' to I at lts inner end rather than at its outer end.

vThe construction of F ig. l is perhaps the least obtrusiveand vconspicuous of the three structures shown. Various modifications as to detail such as, for example, the exact styles and locations of the tension spring, the size, shapingund location of the grip J, the manner ot connecting'A the lever B with the slide I, etc., may be made without'departing from the spirit of my invention which is embodied in the following claims.

l. In eye-glasses provided with spring pressed nose clamps, slidable finger pieces adapted to operate said nose clamps.

2. In eye-glasses provided with u pair ot movable nose clamps, means interposed between each nose clamp and eyeglass tramo adapted to hold said nose clamp in closed so Y.

position, and an independent slidable finger piece connected With and adapt-ed to operate movable linger piece adapte d o.operate.the

same. Y

4. In eye-.glasses provided with pair-of movable nose clamps, an independent finger piece for each nose clamp adapted to operate the same, said finger piece comprising a plunger connected as toone end With the nose clamp, a sleeve surrounding said plunger, and a spring interposed between said plunger .and said sleeve, substantially as and -for the purpose described.

5. Ineyeglasses provided with nose clamps slidable linger pieces adapted to operate said nose elamps in closed position.' 20 6. In eyeglasses provided with pivoted Y spring-pressed nose clamps, slidable finger piecies adapted to operate said nose clamps.rv In testimony whereof I 'have hereunto setA my hand in the presence oftwo subscribing 2.5
