T0 at whom it may concern;

Be it known that I, WILLIAM H. SPANGLER, acitizen of the United States, residing at Pittsburg, in the county of Allegheny'and State of Pennsylvania, have invented new and usefulImprovements in Eyeglasses, of which the following is a specification.

This invention relates to eyeglasses.

One object of the invention is to improve and simplify the construction of the bridge; furthermore, to dispose the resilient loops thereof in such manner that they will be concealed by the posts.

A further object of the invention is to construct the bridge, nose-pieces, and springs, which are adapted to engage'beneaththe eyebrows of the wearer to hold the glasses in position, all from a single piece of wire or resilient material, thus materially reducing the expense attending the manufacture of the glasses and improving their construction.

With the foregoing and other minor objects in view, which will appear as the description proceeds, the invention resides in a bridgepiece having a plurality of loops at each end, one loop at each end being detachably connected with the adjacent post and the other loop being disposed at an angle thereto, so as to lie in a plane parallel with the plane of the lenses and to be concealed from sight behind the post, said last-mentioned loop serving to produce the resiliency necessary forholding the glasses in position,

The invention also resides in the combination and arrangement of parts and in the precise details of construction hereinafter described, and claimed as a practical embodiment thereof.

In the accompanying drawings, forming part of this specification, Figure 1 is a rear elevation of a pair of glasses constructed in accordance with the invention. Fig. 2 is a vertical central section thereof. Fig. 3 is a detail perspective view of the improved bridge. Fig. 4 is a plan View of a post, showing one side of the bridge attached thereto, the lens being partly broken away. Fig. 5 is a view similar to Fig. 1 of amodified form of theinvention. Fig. 6 is a vertical central section thereof. Fig. 7 is a perspective view of the invention, showing the form illustrated in 7 Figs. 5 and 6.

Like reference-numerals indicate corresponding parts'in the dlfierent vlews.

. The-*refer-ence -numerals 1 2 indicate the lenses, and 3 4 indicate the posts, which are of well-known construction.

As shown in'Fig. 3, the bridge5 is formed at each end with a plurality of loops 6 and 7 said loops being disposed at a right angle with respectto each other, so that each of the loops 7 may be fitted into one of the posts 3 4 and secured thereto by means of the screw 8, and each of the loops 6, which together produce the necessary resiliency of the bridge, lies concealed behind one of the posts 3 4 in a plane parallel with the planes of the lenses 1 2, as clearly shown in Figs. 1 and 4. Each of the loops 7 is closed entirely by bending the end 9 thereof back upon itself until it terminates adjacent to the portion 10, for which reason accidental disengagement of said loop from the screw 8 of each post is prevented.

In the embodiment of invention illustrated by Figs. 1 to 4, inclusive, any convenient form lie in a plane parallel with the plane of the lenses and be concealed behind the adjacent post. The nose-pieces 13 in the second form of the invention are produced by an extension of the loop 7, which is twisted, as' shown in Fig. 6. The material from which the nosepieces 13 is formed is extended upward to produce the spring-arms 14, which are adapted to engage beneath the eyebrows of the wearer and to assist is securing the glasses in position.

It will be .observed that the bridge 5, loops 6 and 7, nose-pieces 13, and springs 14 are formed from a single piece of wire or resilient material, whereby the strength of the glasses Having thus described the invention, What is claimed, and desired to be secured by Letters Patent, is

1. An eyeglass comprising lenses, posts and a bridge having a plurality of loops at each end, one loop at each end of the bridge being disposed in a plane parallel to the plane of the lenses and being concealed behind the adjacent posts, said loops together providing the resiliency of the bridge, the other loop at each end of the bridge being closed and attached to the adjacent post.

2. An eyeglass comprising lenses, posts and upwardly-extending springs adapted to engage beneath the eyebrows, and a bridge having tWo loops at each end, one of each of said pair of loops being disposed in a plane parallel to the plane of the lenses and concealed behind the adjacent posts, said loops together providing the resiliency of the bridge, the other loop of each pair being disposed at a right angle With respect to the first-mentioned loop and detachably fastened to the adjacent post, the springs, bridge and loops being all formed of a single piece of Wire.

In testimony whereof I afiix my signature in presence of two witnesses.

WILLIAM H. SPANG LER.
