EYE GLASS-MOUNTING.

Specification ofletters Patent.

Patented Sept. 10, 1912.

Application filed January 17, 1912. Serial No. 671,724.

an eyeglass]uounting, of the type inquestion, with a simple and convenient device for supporting the coiled spring removably in operative position. To this end 1 cmploy a slotted post adapted to receive the coiled portion'ot the spring, with one end of'the spring seated in the slot to anchor the spring, and in order to retain this end of the spring securely in place, while the eyeglass-mounting is in use, the post is provided, at the upper end of the slot, with inwardly-projecting members or lugs, these members normally overhanging and retaining the spring in the slot, owing to the angular position assumed by the end of the spring in consequence of the torsional ac tion thereof.

Another object of the invention is to produce an eyeglass-unmetlug in which both the nose-clamp lever, or finger-lever, and the spring, may bemounted upon a Single post or projection, .the spring being also an ehored at one end. by said post, and. being readily removable therefrom. To this end I employ a construction in which the lever in question is pivolcd upon a post, this post having a flange, outside of the lever, to confine the latter against its ln-raring, and the post being also slotted, beyond said flange, to receive the end of a coiled spring which is removably mounted upon the post.

In the accon'q'mnying (.lrawiugs:--higuro 1 is a. plan-view, on a greatly enlarged scale, of a portion 0'! an eyeglasshiollining en1 bodying the present invention; Fig. 2 is a front-elevation, partly in section, showing the same parts; Fig. 3 is a side-elevation of the post illustrated in Figs. 1 and and Fig. 4 is a horizontal section, looking upwardly, on the line 4.-4 in Fig. 3.

The invention is illust 'ated as eu'ibodicd in an eyeglass-mounting in which the general form is familiar. Figs. 1 -and 2 show a portion. of the bridge 5 and one of the lenses 6, together with lens-straps 7, lens- -clips 8, and a bearing-member or body 9 connecting these parts, and all of ordinary form. These figures also show a nose-clamp lever 10 of ordinary form, provided with the usual finger-piece 11 for actuating it, and with a nose-clamp 12 carried upon its inner end.

The invention resides particularly in the post by which the n0se'-elamp lever 10 is pivoted upon the bearing-member 9, and

which supports and secures in place the spring for actuating the noseclainp lever.

The nose-clamp lever is seated-upon the upper surface of the bearing-member 9, and is pivoted. upon. a stud or post 13, which has a screw-threaded lower extremity screwed into the bearing-member. This post is provided. with a flange 14: which lies just above the nose-clamp lever, thus confining the latter closely against the bearing-member, and restricting it to swinging movements in a horizontal plane. The portion 15 of the post above or beyond the flange serves as a support for a coiled spring 26 of flat spiral form, by which the nose-clamp lever is ac tuated. The outer end 170i this spring is in the form of a hook, which engages a vertical portion 18 of the nose-clamp lover. The inner end 10 of the spring is straight. as shown in Fig. 1. The portion 15 of the post is slotted inwardly from its. end, and in the slot so formed the straight" end 19 of the spring may be readily introduced before the hooked end 17 engaged with the noseclamp lever.

A an ore of the present invention resides particularly in the means employed to retain the end 1!) 01'' the spring in the slot 16. To this on d the postis provided, at the upper end ol the slot, with inwardly projecting lugs or overhanging portions 21, which, in the illustrated (ai'llnnlilnent ot the invention, are )ro.hu:ed by cutting away or bcveling the metal at points 20 on opposite sides of the slot, as shoun particularly in Figs. 3 and 4. Accordingly, when the hooked end 17 of the spring is engaged with the noseclainp lever, the. resulting torsion in the spring causes the end 1.) to assume the angular position shown in Figs. 1. and 2, whereby it firmly engages the surface of the post beneath the lugs 21., being tl'lus locked in. place by thelatter. Owing to this arrangement, the spring cannot work off from the post during the use of the eyeglass mounting." 'VVhen it; is necessary, 'however, to replace or repair the spring, it can be very easilyremoved by first detaching the hooked end 17- and then swinging the end 19 into position to register with the upper extremity of the slot 16, so as to disengage it from; the lugs 21 and permit the spring to be withdrawn lengthwise oi the post.

The arrangement above described, in addition to the novel and effective means for, locking the'spring in place, hasthe further advantage that it produces a simple and compact arrangement-in which the noseclamp lever and the spring are both mounted upon the same post, while the spring may readily be removed from the post With-. out releasing the nose-clamp lever from 010- erative position o m i I The threaded extremity of the post 13 is' illustrated, in Fig. 2, as being threaded in a i right-hand (lire'ct-idn, so thatthe torsional action of the spring 16 cannot rotate and unscrew the post. Obviously,a left-hand; thread should be used Where the tendencyi of the spring is to rotate the post in a leftj hand direction. The use of a threaded ex-E tremity on the post is not essential, however, i I as other Well-known eXpedi-ents may be em ployed to fix the post to the bearingf member. g

I claim p p 1. An eyeglass-mounting having, in, combination, with a nose-clamp and a pivotally movable lever connected therewith, a coiled spring connected, at one end, with said lever, and a post upon which the coiled port-ion of the spring is mounted, the post being slotted to receive the other end of the spring and having inward projections at the upper end of the slot, adapted to retain the spring on the post when its end assumes an angular position in the slot in consequence of the torsional action of the spring.

2. Aneyeglass-mounting having, in combination, a nose-clamp a lever upon which the nose-clamp is mounted, a fiat bearingmember engaging one side of the lever, a stud, projecting from said bearing-member, upon which said lever is pivoted, the stud having a flange engaging said lever on the opposite side from the bearing-member and being slotted longitudinally from its end, and. a coiled spring mounted on the stud beyond said flange and removable over the end thereof, one end of the spring being con neeted with said lever 'and the other end being seated in said slot.
