EYEGLASS-MOUNTING.

Application filed July 1, 1919.

Z 0 all whom it may concern Be it known that I, TVILLIAM T. Hnnnnm 503*, a citizen of the Cnitcd States, residing at San Antonio, in the county of Bexar and State of Texas, have invented certain new and useful Improvements in Eyeglass- Mountings, of which the following is a specification.

The present invention relates toimprovements in mountings for eye-glasses, and consists in certain improvements and changes made in the eye-glass mounting shown and described in my prior Patent No. 1,259,015 granted March 12, 1918.

The chief object of this invention is to provide an improved mounting in which the nose clamps are made in separate pieces from the guard arms that support them, as this construction is productive of many advantages, among which might be enumerated the following:

First, the nose clamps are apt to become worn out, corroded or broken, while the guard arms still remain intact, so that where both the guard arms and nose clamps are 'made in one piece, the guard arms would have to be discarded. This involves a useless expense and by my invention I am en-' abled to further use the guard arms by removing the worn out, corroded or broken nose clamps and attaching new clamps to the same guard arms.

Second, by making the two parts separate the guard arms may be manufactured of some rigid material that is cheaper and more easily procured than the resilient material out of which the nose clamps must be made.

Third. guard arms as now made in one piece with the nose clamps being of resilient material are apt to be bent and distorted when clamped violently in the act of applying the glasses to the nose.

These and other disadvantages are removed by so constructing these parts that the guard arms may be made separately out of rigid material and the nose clamps at tached thereto.

With the foregoing and other objects in view which will become apparent to those skilled in this art, the invention consists in the constructions, combinations and arrangements of partshereinafter described and claimed.

broken away, showing an improved mounting constructed in accordance with the oresent invention.

Fig. 2 is a broken away.

Fig. 3 is a perspective view showing parts involving this invention as detached.

Referring more particularly to the drawings, 1 designates the lenses having the rims 2, to which the lens clamps 3 are attached. The usual brid e piece is indicated at 1, which is connected to the lens clamps 3 by the posts or screws 5. These parts may be of the usual construction.

Fig. 3 shows the improvements in the detached positions, wherein 6 designates the lever formed with the enlargement 7 having a perforation 8 adapted to fit about the post or screw 5, the portion 7 being enlarged to provide an extensive bearing surface on which the lever may turn. At 9 appears the finger piece by which the lever is made to turn on the post or screw 5. This finger piece 9 extends from one end of the lever, the other end of said lever being bent or twisted as shown at 10 in order to bring the smaller thickness of the lever end into a vertical position to better withstand the strain imposed thereon by the weight of the guard arm and nose clamp.

The outer end of the twisted portion of the lever is formed into a loop 11 extending in a horizontal direction and from the free end of the loop depends the guard arm 12. The loop 11 is desirable to facilitate manufacture and it enables the guard arm to be carried outwardly from the lever in a position best suited to supporting the nose clamp.

The lower free end of the guard arm 12 is provided with holes 13 for the passage of the rivets 14lor other fastening means. These rivets 1 1 also pass through openings 15 made in the lower end of the nose clamp, which as shown is constructed of long and short arm being preferably bent toward the long arm and having its upper portion resting against the long arm for purposes of strength and to bring the arms into proper positions for holding the nose pads 18. The arms 16 and 17 have enlarged heads as shown with perforations 19 to receive the rivets or other fastenings 20, which pass through similar perforations in the nose pads 18.

plan view also with parts arms 16 and 17 respectively, the short I Springs 21 are passed about the posts 5 and have their opposite ends engaglng respectively against the lens clamps 3 and the levers 6, as shown in Fig. 2, such springs serving to yieldably hold the levers and guard arms in such position as to cause the nose clamps to bind against the sides of the the levers in the opposite direction and result in binding the nose clamps tightly against the sides oi? the nose.

From the foregoing it will be understood that the levers and uard arms are made sep-' arately from the nose clamps l'r', which en- I ables me to construct these parts out of ditferent materials suitable to the functions of each. The nose clamps are intended to be made out of spring metal to give them the required yielding pressure against the nose, but this material is expensive and apt to become corroded, worn and broken, in which event the nose clamps may be removed from the guard arms and discarded. The rivet fastening forms a convenient means whereby detachment and attachment of the nose clamps may be effected.

On the other hand the levers and guard arms may be made out of some cheaper material that is rigid and not so apt to be distorted when the finger pieces 9 are violently gripped.

I desire it to be understood that various changes may be made in the constructions, combinations, and arrangements or parts herein described, provided such changes fall within the scope of the appended clalms.

Vdhat is claimed is:

1. A mounting for eye-glasses comprising lens clamps, a bridge, posts connecting said lens clamps and bridge, levers pivoting about said posts, rigid guard arms depending from said levers, resilient nose clamps composed of long and short arms secured to said guard arms, and pads secured to the long and short arms or said nose clamps.

2. A. mounting for eyeglasses, comprising rigid guard arms, resilient nose clamps and having enlarged heads at the free ends thereof for two point engagement on. a nose, said clamps being detachably secured to the guard arms at the bends ofthe U, and nose pads on the enlarged heads off said clamps.

o. In an eyeglass mounting, the combinaformed from a metal strip bent U shaped tion with lens clamps and a bridge, of posts connecting said clamps and bridge, laterally extending levers centrally pivoted on said posts. angularly disposed handles at one end of said levers, and integral therewith, open loops on the opposite ends of the levers and integral therewith, rigid guard arms depending from said loops and flared at their lower ends, substantially U shaped nose clamps formed of resilientimaterial and detachably mounted on said'guard arms with the bend of the U at the flared ends of the arms, said clamps being sprung outward from the arms, nose pads detachably mountend on the upper ends of said clamps, springs between said lens clamps and levers, and a stop on each of said levers to limit movement thereof.

In testimony whereof I affix my signature.

WILLIAM T. HENDERSON.
