EYEGLASSES.

To all whom'it may concern:

Be it known that I Gosrav A. Bauer, a citizen of the United States, and resident of Rochester. iu the county of Monroe and State of New York, have invented certain new and useful Improvements in Eyeglasses, I

of which the following is a specification.

This in\'ention relates to eye glasses of the kind in which. the. nose guards are carried by pivoted arms and pressed together by means of springs acting on the arms.

The object of the invention is to provide .eyeglasses of the kind in question with a novel and simple construction of the pivot ]o1nts of the noseguard arms, which shall be secured against accidental derangement while permitting the 'parts :to be easily separated when necessary.

To this end the invention consists in a construction in which the nose-guard'levers themselves. when in operative position, act to secure the pivot pins in place, while the plvot pins act to secure the noseguard levers in place.

In the"; drawings .F igure 1 is a rear elevation .o fxa pan of eyeglasses. en'lbodymo the present invention, with the nose-guarc 'levers shown in vertical section; Fig. 2 is a plan view of the eyeglasses shown in Fig. 1-;"Fig. i3 is a section on the line 3-3 of Fig. 1,,l0oking from right toleft and on an enlarged scale; and Fig. 4 is a plan view of the nose-guard lever, showing the pivot pin and the adjacent part. of the frame in -mounting are connected, in the usual mannor, with a rigid bridge 9. The mounting is'also provided with the usual lens straps 1 and 2; extending along the edges of the lenses.

The nose-guard levers pass from front to rear of the mounting through the openingsin the body portions, and are provided with any ordinary or suitable form of nose guards .6, while their forward ends are formed in a Well known manner to provide finger grips by which the levers may be swung to move Specification of Letters Patent.

the nose guards apart. The levers 8 are pivoted within the bod; portions .of the mount-ing by means of pivot pins 11, which pass through a-lining perforations in the-6o upper and lower members ofthe body portions and in the nose-guard levers. The pivot pins are provided at their upperends with heads 11, which prevent their droppii'igout of place. The remaining portions of the pins, however, are of no greater diameter than the perforations in which they rest. so that the pins may be readily inserted in place when assen'ibling the mounting. The lower portions of the pins are reduced in diameter, but are n' 'ivided with enlarged ends 11. Between these ends and the body portions of the mounting coil-ed springs 10 are mounted on the pivot pins.

The springs 10 have primarily the function of swinging the nose-guard levers-to cause the nose-guards topress against the nose. One end 10 of each spring engages one of the lensstraps 2, as shown in Figs. 1

and 4, while the other end 10 of each spring 30 engages the nose-guard lever. The (coiled portion of the s ring is of sufiicient-diameter to pass over tie enlarged endll on the pivot pin, but after the spring has been put in place its torsional action causes its coiled portion to be pressed againstone side ofthe pivot pin, from which it results that the enlarge end of the pin prevents the spring from being displaced from the pin.

To secure the pivot pins in place each pin has an annular groove 14: formed in position ,to register with vthe openingbetween the upper and lower. members of the body portion. When the nose-guard lever is in place and is under the influence of its spring 10 the lever moves transversely with respect to the pin until it enters the groove therein, and thus engages or interlocks with the shoulder formed by the body of the pin below the groove. In consequence of this position of the lever the/pin is positively retained in? place. and cannot be displaced upwardly. hen it is necessary. however, to take the =mounting apart. thenose-guard lever may be easily pushed' to a positionii'n which its 1 5 perforation registers wit h 'th e shouldered portion of the pivot pin, and lthe pivot pin may then be removed to release the noseguard lever from the body portion of the mounting.

I claim 1. A n'iountingfor eyeglasses comprising pivot pin to prevent longitudinal displacement of the pivot pin.

- 2. A mounting for eyeglasses comprising a lens support, parallel separated members carrying the lens support and having alining perforations, a perforated nose-guard lever 15- lying between said members, a pivot pin passing loosely through the perforations in said members and said lever and having a shoulder adjacent to the lever, and a sprlng engaging the lever and operating both to 20 swing the lever on the pivot pin and to hold the lever in position to engage the shoulder on the pin, so as to prevent longitudinal displacement of the pinl GUSTAV A.
