NOSE-GUARD FOR EYE GLASSES.

Specification of Letters Fatent.

Patented Feb. 4, 1908.

Application fiiei February 12. 1907. Serial. No. 357.046.

To all whom it may concern:

Be it known that I, DALLAS F. GREEN, a citizen of theUnited States, residing at Fort Wayne, in the county'of Allen, in the State of lndiana have invented certain new and use ful Improvements in Nose-Guards for Eyeglasses and I do'hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to' improvements in nose-guards for eyeglasses.

The object of my invention is to provide an eyeglass guard adapted to directly apply' the holding pressure thereof at the point where the greatest frictional contact is required in use, and at the same time preserve the desired elasticity of the guard to secure a ready self adjustment thereof in conformity to its holding surface and also to secure such a compactness of arrangement as to materially reduce the usual unsi htliness of the guard without impairing its sasticity.

My resent invention consists 'of a noseguard for eyerglasses formed of a single piece of spring-metal, preferably having its lower extremity considerably extended to increase its holding power, and having its upper portion provided with an inwardly extended coiled spring connection with the supporting lens clip in compact relation therewith, and adapted to materially aid the self adjusting flexibility of the guard.

The principal novel feature of my invention resides in the means for imparting to the guard its elasticity, and for rigidly securing it upon its mounting.

Similar reference numerals indicate like parts throughout the several views of the drawings in which Figure 1 is a rear elevation of a pair of eyeglasses partly broken away, and showing the relative arrangement of my invention in operative position. Fig. 2 is a plan view of the same- Fig. 3 is adetail sideview of my invention showing the manner of securing the same, in position, the lens-clip to which it is secured being shown in cross-section on line x-w of Fig. 1 looking to the left. Fig. 4 is a similar View with the section of the lensclip omitted. Fig. 5 is a 'side-yiew of the same showing the portions of the guard from which the coiled springs are formed as they' 'appear in the blank. Fig. 6 is a vertical central section. of that portion of the lens-clip shown in Fig. 3 and taken at right-angles to such cross-section. Figs. 7 and 8 show a slightly modified form. of my invention, in which the blank from which the coiled springs are formed is not integral with the guard and has the outer ends-thereof integrally united. Fig. 9 is a side view of another slightly modified form of my invention in which the coil springs are formed of a single piece of wire, which in the blank is in the form of a narrow horizontally arranged loop whose looped end is soldered to the guard at or near its inner edge, as shown in Fig. 10.

The lenses 1 of the usual construction, are provided at their inner ends with the, usual or other proper lens-clip 3 by means of the bifurcated studs 2 and the stud screws4, and are yieldingly connected in the usual hori- Zontally alined relation by means of the bridge spring 5. of common form whose ends are rigidly connected to the respective clips 3 by means of the holding screws 15, Fig. 6, in

the usual manner.

The body 6 of the nose-guard may be of any proper contour and dimensions, and may be formed of any proper material, but is preferably made of suitable spring metal and in the general outline of a human ear with the lower portion 14 inwardly and forwardly extended to exert a bracing action upon the nose in use. The'body 6 may also have any desired'size and-number of lateral apertures as shown to admit portions of the nose-surface, and thereby increase'its holding powerin a well understood manner.

The front of the guard-body is provided, somewhat above its longitudinally central portion, with a pair of springs 7 either integral, as shown in Figs. 3, 4 and 5, or fixed thereto in any proper manner, preferably by riveting as shown In Figs. 7 and 8 or by soldering, as shown in-Figs. '9 and 10. When these s rings are integral they are preferably forme from a pair of blanks 9 extending inw'ardly from the inner, edge of the guard in slightly oblique relation with theirnee ends 8 turned to a vertical position and in ap roximately parallel relation, as shown in igs. 4 v

and 5. These free ends 8 are properly separated and may be oppositely notched upon their adjacent edges to receiving the holding screw 15 in the cllps 3, andare arranged ad jacentto the inner face of the bridge-spring 5, as shownin Fig. 6. The blanks 9 are each formed into one or more coils attheir inner end to form the coil springs 7 after which the ends 8 are arranged in their normal relation as before. 7 V

When the blank from which the coil springs are formed is fixed in positionby riveting it is preferably in the form shown at 12 in Fig. 8, 1n which the sides thereof'are connected at the outer end as at 10, and is fixed to the clip-by the screw -]5 which passes through the opening 11. The coil springs 7 are formed from the blank 12 bythreading I the inner end thereof through the longitudinal opening therein and coiling it upward in an obvious manner. a

-Where the springs 7 are formed of a single piece of wire, the wire is first formed in a.

tween the nose-guard and the supporting lens-clip enables me to secure a very compact arrangement which'obviates the usual un-' si htlines's' thereof, and materially. aids, the 'se f adjusting flexibility of the said guards,

and consequently increases the comfort and convenience with which they areiworn.

Having thus described my invention and, the manner of operating the same, what I desire to secure by Letters Patent is:

1. A nose-guard foreye-glasses consisting of an apertured guard-plate arranged entirely atthe rearof its support, and provided upon its forward edge'with anfin'tegral coiled heli-" cal spring arranged both aboveand below its support, adapted to multiply the self-adjust.-

ing flexibility of the guard, in combination with a spring nose bridge; v 2. In a nose -guard for eyeeglasses formed) entirely of spring metal, an oblique spring metal apert ired guard-plate arranged at the 7 rear ofits support, and provided substantially; j 15 3., coiled helical spring-connection to the sup midway of its ends with-a divided lateral porting lensclip to increase the self adjusting properties of the guard in combination with a spring bridge. t 3. The combination -1n eye-glasses of a arranged entirely at the rear of the said bow, and provided u on its front edge with coiled helical springs means of which it is fixed its self-adjusting flexito its sup ort and bility is increased. p

' 4. An eyeglass nose-guard fbrmed ofan a 1- ertured spring metal plate arranged at t e rear of its support, and united to the support- 1 ing lens-clip at the rear ed e thereof by meansof a divided coiled helica spring connection in compact arrangement, whereby the self-ad justing flexibility of the guard is appreciably multiplied in combination with a springbow. 1
