NOSE-GUARD FOR EYEGLASSES.

Specification of Letters Patent.

Patented Sept.4, 1906.

Application filed Deoember 30,1904. Serial No. 239,011.

To all whom it may concern.-

Be it known that I, ALBERT M. WARD, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Nose-Guards for Eyeglasses, of which the following is a specification, reference being had to the accompanying drawings, which form a part of this specification.

My invention has reference to a nose-guard for eyeglasses, having for its aim an adjustable nose-guard of superior efliciency and utility; and it consists of the structure hereinafter described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a view in front elevation. Fig. 2 is a view in section on the line 2 2, Fig. 1. Fig. 3 is a detail view of the blank from which the body .of the guard is formed. Fig. 4 is a view from the reverse side of theguard from that shown in Fig. 2. Fig. 5 is a detail view of the guard in perspective. Fig. 6 is a detail view showing the guard attached to a rimless eyeglass. Fig. 7 shows a modification in the construction of the branch arms.

The purpose of my invention is to provide a guard that may be freely and readily adjusted in order to conform to the shape of the nose.

In the drawings, 0. represents eye-wires, or the wires about the lenses y, and 1) represents any customary attaching-post upon which a guard is mounted, while 0 represents the spring connecting the posts. Where rimless lenses are employed, the attaching-posts are commonly formed with straps k.

The nose-guards within the scope of my invention are formed with a metallic body consisting, essentially, of a perforated shank d, to be secured upon the attaching-post, an integral curved arm e projecting from one side of the shank d and provided with branch arms f, upon the outer extremities of which may be mounted suitable bearing-surfaces g. Integral with the shank (Z is also a brace-arm h, preferably recessed on its free extremity, as indicated at 'L, to rest astride the adjacent eye-wire or the strap of the attaching-post, as the case may be. The body of the guard, comprising the shank d, the curved carryingarm 6, with its branch arms f and brace-arm is constructed from a single iece of suitable sheet metal, the blank struc from the sheet metal being indicated in Fig. 3. After the blank is formed the curved arm 6 is given a further bend to bring the extremity of the arm closer to the shank, as indicated more particularly in Figs. 2, 4, and 5, the curved arm in the completed guard being curved approximately of a spiral form or of a form approaching a spiral, the adjacent portion of the curved arm being caused to overlap the free end of the brace-arm h. The brace-arm h is also bent outward or away from the curved arm a.

I do not limit myself to the employment of eye-wires, as my invention is equally applicable to rimless glasses, in which case the recessed extremity of each brace-arm 'would rest upon the strap of the attaching-post, as shown in Fig. 6. The free extremity of the branch arms f may be made of disk form and perforated to receive proper independent bearingsurfaces g, or they may be made cup-shaped, as shown in Fig. 7, independent bearing-surfaces being dispensed with; It will be evident that with a guard so constructed the bearing-surfaces of the guard may be changed at different angles and into different positions by simply changing the position of the curved arm 6. All the bearing-surfaces can be altered to conform to the shape of the nose by simply altering the position of the curved carrying-arm e and without changing the position of the branch arms relative to the curved arm on which they are supported, such a construction rendering it much more convenient to change the bearing-surfaces of the guard, inasmuch as all the bearing-surfaces can be changed simultaneously by simply changing the arm 6, as all the bearing-surfaces may thus swing together when the arm 6 is bent toward or from the nose, while at the same time, if desired, each branch arm can be adjusted independently should there be necessity for so doing.

The object of the brace-arm is to prevent lateral play or movement of the guard, and thereby prevent the attaching-screw, which unites the shank of the guard to the attaching-post, from working loose.

I would have it understood that the branch arms may either be provided with integral or with attached bearing-surfaces.

It will be evident that the bearing-surfaces of the guard extend back of the inner plane of the lenses, while they are at the same time adjustable to conform to the nose of the wearer, thereby constituting an adjustable offset guard.

What I claim as my invention is- 1. A nose-guard for eyeglasses constructed of an integral piece of metal comprising a Vertical attaching-shank, a brace-arm projecting laterally from the attaching-shank toward the adjacent eyeglass, a carryingarm projecting downward and inward from the attaching-shank on a curved outline, and branch arms supported upon and projecting from one edge of the carrying-arm, each of said branch arms provided with a bearingsurface.

2. A nose-guard for eyeglasses constructed of an integral piece of metal comprising a. vertical attaching-shank, a brace-arm projecting laterally from the attaching-shank toward the adjacent eyeglass, a curved carrying-arm projecting inward from the attaching-shank, and plural branch arms supported upon the carrying-arm and provided with bearing-surfaces, the bearing-surfaces being simultaneously adjusted by adjusting the position of the carrying-arm.

3. A nose-guard for eyeglasses constructed of an integral piece of metal comprising a vertical attaching-shank, a brace-arm projecting laterally from the attaching-shank toward the adjacent eyeglass, a carrying-arm curved inward and upward, and branch arms supported upon the carrying-arm provided with bearing-surfaces.

4. A nose-guard for eyeglasses constructed of an integral piece of metal comprising a vertical attaching-shank, a brace-arm projecting laterally from the attaching-shank toward the adjacent eyeglass, a carryingarm, plural branch arms projecting from the carrying-arm, the branch arms being independently adjustable, and simultaneously adjustable by the adjustment of the carry ing-arm.

5. A nose-guard for eyeglasses comprising an attaching-shank, a brace-arm projecting outwardly from the attaching-shank, a carrying-arm projecting inwardly from the attaching-shank intermediate the free end of the brace-arm and the opposite end of theattaching-shank and upon a curved outline, and branch arms supported upon the carrying-arm.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

ALBERT M. WARD.
