EYEGLASSES.

To all whom it may concern:

Be it known that I, LEO F. AM, ,of the city of, Albany, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Eyeglasses; and I dohereby ,cleclare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forminga part of the specification, and to the reference-numerals marked thereon. a

This invention relates to eyeglasses of the type in which the lenses are connected by a substantially rigid support holding them against relative movement, and the nose guards are arranged to swing thereon and are operated by extensions serving as finger pieces; one object of the invention being to provide a mounting in which the support has spring portions acting to position the nose guards and also, if desired, to retain the guards thereon; and a further object being to provide nose guardshaving shiftable fulcrums which cause the guards to move away from the nose quickly at first and then slowly, thus expediting the removal or the positioning of the eyeglasses without increasing the length of movement of the nose guards.

To these and other ends-the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully' described, the novel features being pointed out in the claims at the end of the specification. Y

. In the drawings: Figure 1 is afront view of a 'pair of eyeglasses constructed in accordance with my invention, parts being shown in section; Fig. 2 is a top view of the same embodiment; the guards being shown in different positions; Fig. 3 'is-a central transverse sectionof thev same embodiment; Fig. 4 is a top view of another embodiment; Fig. 5 is a front view of the'mounting of the same embodiment showing parts in section, and Fig. 6 isa-cent-ral transverse section of the embodiment shown inv the last two figures.

The invention which is susceptible of be-' Specification of Letters Patent.

. caused to first portion preferably in the form of lugs which are suitably secured to lens attaching members 3 of any desired construction forming part of the support and each having,.in this instance, edge bearing portions extending in opposite directions to coiiperate with the edge of a lens. The nose guards C are mounted on the support and each preferably rests on a seat formed by one of the lugs 2 and has a rocking bearing on the support, or in other words, has a shiftable fulcrum, whereby the nose engaging member is move quickly away from the nose and then slowly so that the removal of the eyeglasses may be expedited without increasing the length of movement of the guards. In the or edge 13 on a guard which bears against a fiat face 011 the inner or proximate side of the edge bearing portion of a lens attaching member, the guard being held against vertical movement 011 the seat 2 by an overhanging lug l4 projecting inwardly over the seat from the edge bearing portion of the lens attaching member and forming with the said seat 2 an open bearing.

The nose guards are positioned and at the same time held on themounting by spring portions of the support which are made preferably from the stock from which the bridge is formed. In this instance the flat stock at each end of the bridging portion is extended rearwardly and horizontally at 4 and is bent flatwise outwardly as at 4*, forwardly as at 5, and inwardly as at 6 and thence forwardly to provide a forwardly ex-- tending spring arm 7 above the seat 2, the

Several bends being employed to form a horizontal loop deflected partially inthe rear of a lens so that it will be inconspicuous and at the same time give suflicient spring to the forwardly extending spring arm 7. At its free end, each arm 7 has a vertical projection 8 extending downwardly to engage within an opening 9 in the forwardly projecting operating arm 10 of one of the nose guards to form a detachable connection I therewith. In positioning the eyeglasses the Patented June 6, 1911.; Application filed June 21, 1907. SeriaLNo. 380,027.

present instance, the rocking I bearing comprises a vertical curved port1on ends of the operating arms 10 arepressed toward each other, and the glasses are placed in a position so that the nose may be engaged on opposite sides when the operatlng arms are released, and in removing the.

glasses the operating arms are again pressed together. To separate the guards from the rest of the mounting the projections 8 on the arms are removed from the openings 9 and the guard is withdrawn rearwardly from the mounting. I

In the embodiment shown in Figs. 4 to 6 the lenses A are connected by a substantially rigid support B the bridge of which is formed from flat stock bent 'to provide an arched bridging port-ion 15 and a vertical open bearing 16 at each end, each bearing being made from a forwardly extending arm at the end of the bridging portion rolled rearwardly and rigidly secured to one of the lens attaching member 17 which may be of any suitable form. Supported on the seat formed by each bearing 16 is a nose guard C which has a forwardly projecting operating arm 18, and a rearwardly extending nose engaging member consisting of the upper pad 19 and the lower pad 20. Each guard carries a pivot pin 21 to depend into one of the open bearings 16, and is held to thelatter by a spring portion on the support which also serves to positionthe guard like a similar portion on the first described embodiment. The spring portions in this instance extend rear- Wardly from the ends of the bridging .portion and are each made from the fiat stock which is bent flatwise outwardly at 21 and slightly downward edgewise to a forwardly extending bend 22, thence inwardly horizontally at 23 andfinally outwardly to provide a forwardly extending spring arm 24 arranged beneath the bearing portion of the bridge. At its free end each forwardly ex tending spring arm 24 has a vertical or up ward extension 25 which engages the operating arm of a nose guard by overhanging the inner edge of the latter at 28, thereby retaining it in place upon the support. The operation in removing or positioning the eyeglasses is the same in this embodiment as in that first described butthe guards are separated from and fitted to the-support in a different manner. move theguards the free ends of the arms 2& are moved toward each other so that the overhanging portions 26 will be moved to positions to permit the guards to be vertically withdrawn from the open bearings.

The invention herein disclosed provides eyeglasses whichare inexpensive to manu facture and simple to manipulate. The

parts are few and the separation or assem- 'bling thereof is comparatively easy as the use of separate springs and 'small screws or other fastening devices is dispensed with, except in the fastening of the lenses.
