CLIP FOR FRAMELESS SPECTACLES.

SPECIFICATION forming part of Letters Patent No. 240,089, dated April 12, 1881.

Application filed December 29, 1880. (No model.)

has for its object the production of an article which is superior in itself, and which may be constructed without making use of the elements which are the chief sources of loss and annoyance to both the manufacturer and user.

The distinctive novelty of myinvention consists in dispensing entirely with the use of screws, rivets, solder, and analogous expedicuts in connectiiigtlie glass and accomplishing an effectual connection, by the employment of a clip having elastic arms and provided with projections which fit into cavities in the glass, as hereinafter specifically set forth.

- It has heretofore been customary to connect the lens being pierced. This construction has been found to be objectionable, in that the clips and nose-piece become detached from each other, and the connections, which are necessarily delicate, become loosened or broken piercing the glass necessarily weakens it, thus causing loss and inconvenience. It is also true that, the clips and nose-piece being of sep' arate pieces and requiriu g skilled labor to connect them, the production of the articlein volves many difficulties which are a source of expense and loss of material. Clips consisting of two arms having projections at their ends adapted to fit in cavities in the glass, and adjusted by a screw or bolt, have also been produced, but are objectionable, in that they do not hold the glass so that it cannot be easily moved in some direction. The clip must necessarily be small, and it has been found, almost invariably, that the glass will oscillate to some extent on the projections of the clip, thus causing the invention in the preferred form.

cavities in the glass to be enlarged or chipped, with the consequent injury to the article.

To obviate these and other objections is the purpose of my invention, the exact nature of which will be readily understood from the detailed description hereinafter presented, in connection with the accompanying drawings, in which- Figure l is a front view of a pair of spectacles embodying the invention. Fig. 2 is an edge view of one glass of same. Fig. 3 is a detached sectional view, showing the relation of the clip to the glass. Fig. 4 is a side view of a clip, and Fig. 5 is a front view of a pair of eyeglasses embodying the invention. Fig. 6 shows the blank from which the parts of the frameless spectacle and eyeglass are out.

A indicatesthe glasses; B, the nose-piece, having the clips 0. The nose-piece B, provided with the clips 0, will. by preference, be stamped out of thin metal, but may be constructed in other ways. it is made in a single piece, and of any appropriate shape. The clips 0 are distinctive, in that they are constructed with elastic arms to, having projections f at or near their ends, the projections being constructed to fit into cavities in the glasses as illustrated in Fig. 3. The projections will, by preference, be rectangular, and the cavities of corresponding shape, the size and other details being such as occasion may require.

In Fig. 4 is shown a clip which embodies the This clip is formed of a single piece having a base, and the arms a which are elastic, having a tension toward each other, and which are supplied at or near their ends with the projections or studs f, and a projection onstud, h, formed preferably on the base between the arms a. The glass to which the clip is to be applied will be furnished with cavities f and h, corresponding with and adapted to receive the projections f and h, whereby, when the parts are united, the glass is very securely held and prevented from moving in any direction.

D indicates the hinge-piece, to which the side arms of spectacles are secured. The hingepiece and clip will, according to my invention, be made in one piece, whereby the labor and expense of constructing them in separate pieces and attaching them by rivets, &c., are entirely avoided.

It will be readily understood that the invention may be practiced in many ways without departing from the essential considerations to which reference has been made.

I have shown in Fig. 6 a blank with the metallic parts of the frameless spectacle, eyeglass, &c., indicated in outline upon its surface, L representing the nose-piece and clips for the spectacle; M, the same for an eyeglass, and N the hinge-piece. It is intended to cut the parts out by means of dies, and after removing them to smooth their surface by passing them between grooved rollers, in the usual way, or otherwise. The projections on the clips may be trimmed down by the use of open mill-wheels or other expedients. The clips on the nose-piece for the eyeglass, after being cut from the blank, are given a quarter-turn, so as to bring their arms in proper relation to the glasses to clasp them.

The foregoing is one efficient method of forming the fork-shaped clip, with its attachment, by cutting the whole from the same piece of metal. It is obvious, however, that the same end may be accomplished in other ways, and I do not, therefore, limit myself to the method described; but

WhatIclaim as my invention, and desire to secure by Letters Patent, is-

1. A fork-shaped clip for spectacles, eyeglasses, &c., formed in a single piece, with its attachment, by cutting the whole out of the same piece of metal, substantially as set forth.

2. A clip for eyeglasses, spectacles, &c., composed of a single piece of metal having elastic arms provided with projections adapted to fit into cavities in the glass, and thus secure the sides and edge of the lens, and forming a clip' for connecting the glass to the other parts of the article, substantially as set forth.

In testimony that I claim the foregoing improvement in frameless spectacles and eyeglasses, as above described, I have hereunto set my hand this 27th day of December, 1880.
