EDWARD BROWN FOX, OF PHILADELPHIA, PENNSYLVANIA.

EYEGLASSES.

SPECIFICATION forming part of Letters Patent No. 437,396, dated September 30, 1890.

Application filed May 20, 1890.

To all whom it may concern.-

Be it known that L'EDWARD BROWN FoX, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Eyeglasses; and I do declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. v

This invention relates to eyeglasses, and has for its object to reduce the number of parts heretofore necessary for securing the eye-wires, the nose spring, bar, or bridge, and the nose-clamp together, thereby diminish? ing the liability of the parts so assembled from becoming loose, and reducing the cost of manufacture both in material required and in the labor necessary to secure the parts together.

Another object of the invention is to render the frame as small as possible, thereby giving it a neat and light appearance, this being effected by reducing the size of the lugs at'the separated ends of the eye-wires.

The improvement consists, essentially,in a single fastening for securing the separated ends of the eye-wires together and at the same time serving to secure the nose spring or bar and nose-clamp to the said eye-wire.

A further improvement consists in a pin which projects from one of the eye-wire lugs, and which is adapted to pass through an opening in the nose spring or bar and a coincident opening in the nose-clamp,whereby these parts are prevented from turning on the fastening which secures them together.

The improvement also consists in the novel features and the peculiar construction and combination of the parts, which will be hereinafter more fully described and claimed, and which are shown in the annexed drawings, in which-- Figure 1 is a front view of an eyeglass or spectacle embodying my invention. Fig. 2 is a detail perspective view, parts being broken away, of the eye-wire, the nose-spring, the

nose-clamp, and the fastening, the parts bein g separated and arranged in their relative position. Fig. 3 is a top plan view of the nose-spring. Fig.4 is a top plan View of the nose-clamp. Fig. 5 is a top plan view of the lug which is provided with the stay-pin.

The eye-wires A are of ordinary construc-' tion, beingseparated at their inner ends,which ends are provided with lugs a a. The luga is provided with the stay-pin b, which is arranged at its outer extremity and projects at right-angles from the face thereof. These lugs have coincident openings, through which the fastening device or screw B passes, the opening in the lug a being threaded. The nose springer bridge 0 and the nose-clamp D are adapted to have their ends placed between the lugs a a, between which they are secured. The screw B passes through the lugs a a and through corresponding openings in the nose spring or bar and the nose-clamp, and serves not only to secure the separated ends of the eye-wires together, but also as a means for fastening the nose spring or bar and 7 5 the nose-clamp to the said eye-wire. The pin 6 is inserted in openings provided in the nosespring and the nose-clamp and prevents them from turning on the screw B, thereby acting in the capacity of a stay and holding the parts rigidly in place. The nose-clamp is in the plane of the eye-wires, and the nose spring or bridge is deflected or curved outward between its ends.

By having a single fastening device for securing the separated ends of the eye-wires and the nose-clamp and the nose spring or bar together the parts are not liable to become loosened, and the lugs a a may be comparatively small, in that the said screw passes 0 through them at right angles.

Having described my invention, what I claim to be new is- 1. In an eyeglass or spectacle, the combination, with eye-wires, the n0se-spring, and 5 the nose-clamp, of a single fastening for securing the separated ends of the eye-Wires, the nose-clamp, and the nose spring or bar or clamp together, said fastening being arranged substantially parallel with the nose-clamps, 1oo

substantially as set forth.

2. In an eyeglass or spectacle, the combination, with the eye-wires having lugs exthem on the ends of the said nose spring or .[o tending from their separated ends and having bar and nose-clamp, substantially as specified.

a stay-pin projecting from the face of one of In testimony whereof Iaflix my signature in the lugs, the nose-clamp and the nose spring presence of two witnesses.
