To all whom t mei/concern:

Be it known that I, ROBERT M. REID, a citizen of the United States, residing at Colorado Springs, in the county of -El vPaso and State of Colorado. have invented a. certain new and useful Improvement -in Mountings for Glasses, of whichthe following is a specification.

This invention relates to glasses ordinarily worn by people, and particularly to what are technically known -as eye-glasses in which the glass lenses are wholly supported from and attached to the nose of the wearer. l

- The object of the invention is to provide a novel form of nose-,piece and mechanism. for attaching the glass lenses thereto in such a way that an unusually strong construction is obtained instead of puncturing the lenses as has always been necessary heretofore, while the'outery rim of each glasslens is supported by a substantially invisible metallic band.

The invention consists in means for carrying out the foregoing objects; which can be easily and cheaply made; which is satisfactory in use, and is not readily liable to get out of order. The invention consists more particularly in the features and details of construction hereafter. more fully set forth in the specification and claims.

Referring tot-he drawings in which similar numerals indicate the same parts throughout the several views,

Figure 1 is a front view of a pair of eyeglasses constructed in accordance with this invention in its preferred form.

Fig. 2 is a plan view of the device shown in Fig. 1.

Fig. 3 is a sectional end view of the lens enlarged, and taken on the line 3--3 of Fig. 1.

Fig.- 4 is a correspondingly enlarged plan l view taken on the line 4 of Fig. 1.

Fig. 5 is a perspective view of the nosepiece frame and the band which binds a lens, all other parts being removed.

In constructing the device of this invention in its preferred form, a nose-piece 10 is provided. Fach end of this nose-piece is divided or split in the process of manufacture into two parallel horizontal arms 12 and 14, separated like the arms of a U whose base is the nose-piece 10. The end of arm l2 terminates in an upnardlyrising finger Specication of Letters Patent.

1G embracing a portion of the circumference of the adjacent lens 18, and two side fingers 20 engaging opposite sides of the lens in the ordinary manner. Similarly arm 14 is provided with a downwardly extending finger .22 corresponding to finger 16, and two side fingers 24 corresponding to fingers 20. The for (ed fingers 20 and 24 serve the very useful purpose of supporting the lens against sidewise movement with reference to the nose piece. The arms 12 and 14 are connected together by a screw 26 bearing right hand threads on one end and left hand threads on the other where it engages respectively the two arms in question, with the result that rotating the screw 26 in one direction tends to draw the arms 12 and 14 together while rotating it in the other direction tends to separate'them.

Journaled upon each screw 26 is a nose gripping device 28 controlled by al spring 30 of the ordinary type. and forming no part of this invention. This nose grip may be omitted when the glasses are to beused in spectacle 'form' with bows attached at the outer edges of the lenses. i

Instead of puncturing the lenses 1S adjacent to the nose-piece and securing them thereto by rivets in the ordinary manner, the lenses are provided on their outer circumferences with V-shaped recesses 32, clearly appearing in Fig. 8, in which are placed circumferential bands of fine wire 34. the opposite ends of these wire bands being provided with transverse cross-bars or hooks 36, adapted, as clearly shown in Fig. 5, to hook into notches 38 provided at the juncture of the respective arms 12 and 14 and their

respective fingers

16 and 22.

' Attention is especially called to the fact J that in the construction above lset forth. the cross bars or hooks 36 on the ends of the wire band engage the nose piece mechanism at single points. thus doing away with the necessity of making more than a single perforation therein for each end of the band, this being especially important where there is so little stock material. The construction has a further advantage that in assembling the eye-glasses, if the parts fit too tight, adjustment may readily he made b v slightly filing the 'cross bars or hooks 3G until all the mechanism coperates properly.

ln assembling the mechanism of this invention, the operator takes a nose-piece construcled' as shown and lirst ioosens up the screw QG. lle then takes thelens 18 which 1s to be applied` places around it the previously prepared band 3l and attaches the lens 1S and holdit in place. The operationV of removing thclens is obviously merely a reversal of the movements just described. y

The fact that the nose piece is m'a'dewith an integral U-shaped opening, whose arms 12 and 14, are sprung together by a sin.-

gle contracting mechanism, in the particular case here illustrated, the screw 2G, very important in that it eliminates pai'ts which might become detached when the screw loosens or is removed. In the construction shown, the screw 26 can loosen materially without any of the parts being able to move sufficiently to release the lens. i

In actual practice, the band 3l maybe made so fine as to be practically invisible so that glasses constructed in accordancewith this invention have all the advantages of the ordinary rimless eye-glasses together. with the very great advantage that the lenses instead of' being weakened by havingone or more holes cut in.tliem for attachment .to

theJl nosepiece are, on the other" hand,"

strengthened bythe adding of the supportingband 34. s., .4,

Where ordinary bow glasses are desired, the bows may be attached in any suitable inamier to the outer edges of the lensesg18, one possible construction being to solder the bow supports to the band 34C at the points named. y

The groove 32 is very important as it seems to render` the band 34 substantially invisible. l

The band 3ft may, of courscbe of metal or any other suitable material.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In mechanism of the class described, a nose-piece, a lens, a band around the lens, an expansible and contractible mechanism non-separable as to its members on the end of the nose-piece engaged by the ends of said band in single openings, adapted to dctachably secure the band around the lens.

In mechanism of the class described, a-

nose-piece, a lens, a band around the lens, and expansible and contractible mechanism integral with the end of the nose-piece detaehably engaged by the ends of said band in single. openings one for each end of the band adapted to detachably secure the band about the lens.

3.

7. In mechanism of the class described, a nose-piece, an nnperforated lens, an expansible and contractible mechanism at the end of the nose-piece, a band around the. lens provided -at one end with a.
