EYEGLASSES.

SPECIFICATION forming part of Letters Patent N 0. 766,571, dated August 2, 1904.

Application filed July 15, 1903. Serial 110.165.5581. (N0 model.)

To all whom it may concern:

Be it known that I, LEO F. ADT, of Troy, in the county of Rensselaer and State of New l forated lugs at 4 of the clips 1 apertures 5 5 being formed therein for a pur- York, have invented certain new and useful I Improvements in Eyeglasses; and I do hereby declare the following to be a full, clear, and

exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My present invention relates to improvements in eyeglasses, and more especially to that class employing a rigid or relatively inelastic bridge-piece connecting the lenses; and it has for its object to provide a pair of opposing nose-guards each embodying a resilient or yielding supporting-arm which is attached to the lens and adapted to rest against the wearers nose and a supplemental nose-bearing portion carried by the supporting-arm and having a portion bearing on a relativelyfixed part of the mounting to form a center about which the nose-bearing portions of the guards move in separating, these portions being extended beyond the bearing on the mounting, if desired, to form operating-handles or projections in convenient positions whereby said guards may be readily operated for applying and removing the device from the nose of the wearer.

Other features of novelty and advantage will be hereinafter more fully explained, and pointed out in the claims hereunto annexed.

In the drawings, Figure 1 is a rear elevation of a device embodying my invention. Fig. 2 is a plan view, partly in section. Fig. 3 is a sectional view on the line 3 3 of Fig. 1,

and Figs. 4 and 5 are views showing the nose- .embodiment, wherein l designates the lenses,

perforated at their inner ends and over which are titted the clips 2 2, and connecting the lenses is a relatively inelastic bridge 3, the extremities of which extend through the perrespectively,

pose that will hereinafter appear.

.ln rear of the bridge and in proximity to the clips are provided nose guards or clamps, each comprising in the present embodiment an attaching-arm 6. extending through the perforation of the lug &, through which may be passed a screw 7 for securing the parts firmly to the lenses. Extending rearwardly and leading downwardly and forwardly and upwardly this arm forms a loop 8, adapted to rest against the wearers nose, a continuation of said arm forming the extended bearing portion 9, preferably inclined slightly rearwardly and inwardly in its normal position. Connected to the guard thus formed and at a point preferably opposite the attached arm 6 is an arm 10, extending forwardly through the aperture 5 in the bridge and terminating at a point forward of the anterior surfaces of the lenses to form operating-handles or projections. These guards are formed of an elastic material, and in their normal posit-ion the bearing-surfaces 9 will be inclined inwardly toward one another.

In applying the device to the nose of the wearer the handles or projections 10 10 are pressed together in any convenient manner, such as by the thumb and forefinger, and as their arms pass through the apertures 5 5 of the bridge said bridge will provide fulcrums, transforming the inward motion of the forward ends of the arms 10 to an outward motion at their rear ends, causing a separation of the bearing portions 9 9 against the torsional action produced by the elastic loop 8 of each guard. and when the pressure upon the forward ends of said arms is removed said torsional action of the loop 8 of each guard will exert a force tending to bring said bearing portions together to properly clamp the nose of the wearer.

The guards may be'advantageously formed of flat elastic material and so bentand formed that the proper degree of pressure will be produced by the nose-bearing surfaces under the action of the elasticity of the material,

' of nose-guards each embodying a downwardlythe parts being so arranged as to produce a l device that maybe applied and removed with the utmost facility.

It will be obvious that in employing a relatively inelastic bridge-piece the relation of the lenses is not altered or disturbed in the mal nipulation of the device.

I claim as my invention 1. In eyeglass-mountings, the combination with a bridge, of opposing nose-guards composed of resilient material each embodying a downwardly-extending loop fixed at one end to the mounting adapted to bear upon the nose of the wearer, and a'supplemental hearing portion connected to one arm of the loop and having a pivotal bearing upon a relatively fixed part of the mounting.

2. In eyeglass-mountings, the combination with a bridge, of nose-guards composed of resilient material each embodying a looped arm fixed at one end to the bridge adapted to rest against the nose of the wearer, and an additional bearing portion carried by one arm of said loop and provided with a portion extending forwardly of the bridge and having a pivotal bearing upon a relatively fixed part of the mounting to form an operating-handle by means of which the guard may be manipulated.

3. In eyeglasses, the combination with a mounting embodying a bridge, of opposing nose-guards each embodying a resilient or yielding arm fixed at one end to the mounting adapted to bear against the nose of the wearer and having a more readily movable portion constituting a supplemental nose-engaging portion and an operating portion connected to said last-mentioned portion and having a bearing upon a relatively fixed portion of the mounting.

4. In eyeglass-mountings, the combination with the lenses and a bridge connecting them,

extending arm and an upwardly-extending resilient arm having its lower end attached thereto, and forming a nose-bearing portion, and an operating portion connected to the resilient arm and bearing on a relatively fixed part of the mounting as a fulcrum.

5. In eyeglass-mountings, the combination with a bridge and opposing nose-guards attached thereto, each embodying an upper nose-bearing portion, a resilient or yielding supporting-arm, having one end thereof fixed to the mounting and an operating portion extending forwardly of the bridge and adapted to bear upon a relatively fixed part of the mounting when said operating portions are moved toward each other to separate the nose-bearing portions.

6. In eyeglass-mountings the combination with the bridge, of opposing nose-guards each' embodying a resilient arm fixed at one end to the mounting and having a yielding 'nose l 1 bearing portion, and an operatlng arm bearing upon a relatively fixed part of the mounting as a fulcrum and forming a loose connection between the latter and the nose-bearing portion.

7. In eyeglasses, the combination with the lenses and a bridge connecting them, of noseguards attached to the lenses having resilient arms each having a portion fixed to the mounting and carrying relatively movable nose-engaging portions, and operating portions carried bythe guards and bearing on relatively fixed fulcrums to provide means by which the guards may be manipulated.

8. In eyeglasses, the combination with the lenses, and a connection between them, of noseguards attached to the lenses having resilient lower arms fixed at one end and adapted to rest against the wearers nose and carrying relatively movable upper portions, and arms connected to said movable portions and bearing on fulcrums to provide means for manipulating the guards.

9. In eyeglasses, the combination with the lenses and a bridge connectingthem, of noseguards each having a resilient arm fixed at one end and having its other end free and adapted to rest against the wearers nose, and an operating portion connected to said arm and bearing on arelatively fixed part of the mounting as a fulcrum.

10. In eyeglass-mountings, the combination with a bridge, of nose-guards each embodying a nose-bearing portion, a resilient supporting-loop,having a relatively fixed portion and an operating portion connected to the nose-bearing portion and adapted to move it laterally against the torsional action of the supporting-loop.

11. In eyeglass-mountings, the combination with a bridge, of oppositely-arranged noseguards each embodying a resilient or yield- IOO ing arm attached to the mounting and having its free end extending downwardly, thence forwardly and doubled upwardly to form a loop, the arms of which are adapted to bear against the nose of the wearer, the free arm of the loop carrying an additional or supplemental nose-bearing portion, and an operating portion connected to the free arm of the loop and forming means bywhich the guard may be manipulated.

12. In eyeglass-mountings, the combination with a bridge having the aperture, of opposing nose-guards each'embodying a nose-bearing portion, a resihent or yleldlng supportingarm, and an operating portion connected to the guard and extending loosely through the apertures in the bridge and adapted to bear upon the side of said apertures when said operating portions are moved inwardly, to separate the guards.

extending above its point of attachment and carrying an additional or supplemental nose- 10 hearing portion.
