NITED STATES A PATENT JOHN OURRIN, OF SOUTHBRIDGE, MASSACHUSETTS, 'ASSIGNOR TO THE AMERICAN OPTICAL COMPANY, OF SAME PLACE.

NOSE-GUARD FOR EYEGLASSES.

SPECIFICATION forming part of Letters Patent No. 324,540, dated August 18, 1885.

(No model.)

To all whom it may concern:

Be it known that I, JOHN CURRIN, of Southbridge, in the county of WVorcester and State of Massachusetts, have invented a new and useful Improvement in Guards for Eyeglass- Frames, of which the following is a specification.

My invention relates to noseguards for eyeglassframes which have a loose connection at their upper ends with the studs which project from the eye-wires, and are thereby enabled to readily adjust themselves toward and from the eye-wires in order to accommodate themselves to the nose of the wearer. To make one form of connection heretofore used, the guard has been bent backward and nearly at right angles to its main portion, and has in the bent portion a slot which receives a tongue, which is formed upon a lug or piece projecting from the stud, the slotted guard being free to slide upon. the tongue to secure its free adjustment.

An important object of the invention is to provide a loose connection for the upper end of the guard which will adjust itself freely and without any grating sound, such as is liable to occur when the slotted guard above described slides upon the tongue on which it is guided, and also to enable the guard to be made of less width than is advisable when it has to be formed with a long slot. Guards have also been made in the form of a loop or compound guard, the metal strip which forms the guard being bent backward and upward at the lower end of the guard proper, and thence carried upward and attached to the eye-wire stud. The guards of this class heretofore made have frequently been slotted at the lower end, so as to receive a tongue projecting from the eye-wire, thereby sustaining the lower end of the guard in such manner that it may adjust itself to the nose of the wearer. The guard has to be of considerable width because of its slots. Andafurther obj ect of myinvention is to provide means of sustaining and steadying the lower end of the guard, which render unnecessary any slotting of the guard, and will shield and protect its lower end and prevent its catching in the clothing.

My invention consists in novel means of combining and connecting the guards with the other parts of the frame, as fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 represents an eyeglass frame embodying my invention. Fig. 2 representsaframe of slightlymodified construction, also embodying a part of my invention; and Figs. 3 and 4. are sectional views, on a larger scale, illustrating more clearly the connection between the upper end of the guard and the stud of the eyewire.

Similar letters of reference designate corresponding parts in all the figures.

A A designate the usual eye-wires, which are connected by a bowspring, B, the ends of which are secured in the usual way to studs a, projecting from the eyewires.

G designates the nose guards, which, as shown in Fig. 1, are bent upward and backward at their lower ends, 0, and thence eX- tended upward adjacent to the eye-wires to the studs a, where the upwardly-extending portionsOaresecured. Thisgiveseach guard a U-shaped or compound forn.

Attached to each eye-wire, as shownin Fig. l, is a hook, I), which extends outward and thence upward, and which receives within it the bent lower end, 0, of the guard O. This hook b sustains the lower end of the guard and confines it sufficiently without preventing its suflioiently free self-adjustment, and it shields and protects the lower end of the guard, so as to prevent its catching in clothing and being bent or broken.

The guards O 0 may be formed by prolongations of the bow'spring B; or they may consist of separate pieces, the upper ends of the port-ions 0 being secured to the studs ac.

At their upper ends the guards O are turnedoutward and are pivotally connected by links (2 with lugs or cars a, which project from the studs a. Through these lugs or. cars a the links d are connected with the studs a. The lugs or cars a may consist of prolongations of the bowspring B, as shown in Fig. 31; or they may consist of separate pieces attached to the studs a, as shown in Fig. 4.

In the example of my invention shown in Fig. 2 the guards G are connected at their upper ends bylinksd with lugs or ears and studs a a, as described with reference to Fig. 1; but the guards are fixed at their lower ends, 6, to the eye-wires A.

The link-connection at the upper end of the guard is very desirable, as it affords ample freedom of movement for the guard and avoids the slotting of the guard and any grating noise or sensation which is disagreeable to nervous persons.

I am aware that it is not new to connect the upper end of the noseguard to the eye-wire stud by means of a link, which is pivoted to swing in a plane transverse to the plane of the eye-wire, in order that the nose-piece may be adjusted to a position out of the.p1ane. of the glasses. This pivotal link-connection does not provide for the free movement of the noseguard toward and from the eye-wire in the same plane therewith, and it is this latter adjustment or movement of the nose-guard which I obtain by the link-connection d.

What I claim as my invention, and desire to secure by Letters Patent, is-

' in described.

1. The combination,with the eye-wire, bowspring, and .a stud attaching said spring to the eye-wire, of a guard connected at its lower end with the eye-wire, and a link connecting the upper end of the guard with the stud ,and providing for the free movement of the guard toward and from the eye-wire in the same plane therewith, substantially as herein described.

2; The combination, with the eye-wire and compound or looped guard, of the hook I), attached to the eye-wire to receive within it the lower part of the guard, substantially as here- 3. The combination,witl1 the eye-wire, bowspring, and a stud connecting the spring with the eye-wire, of the looped guard O 0, having at its upper end a link-connection with the stud, and a hook, I), attached to the eye-wire for receiving the bent lower portion of the guard, substantially as herein described.

JOHN CURRIN.
