form the guard that it can be readily adjusted to t different contours of noses and that the lenses can be broughtinto any required position before the eyes.

These objects l attain in the following manner, reference lbeing'had to the accompanying drawings, in which Y Figure lis a view of a pair of eyeglasses, showing my improvement. Fig. v2 is a section on the line '2 2, Fig. 1. Fig. 3 is a detached view of theguard. Fig. 4 is a perspective view showing the guard, posts, and bow detached. Figs. 5 to 16, inclusive, are views showing the'guard adjusted to dierent positions. Fig. 17 is a view of a modication, and Fig. 18 shows an extendedhead on the guard.

A A are the lenses, to each of which is attached the ordinary post B, having a socket b, formed by two flanges b b', and each post l is secured to its lens, in the present instance by means of clips and a screw. The socket b is deep enough to receive the end of the bow C and an arm d of the guard D. Both the bow and the arm t snuglyy between the langes b. f I

y vOn the end of the arm d of the guard D is a head d', forming shoulders d2, which rest upon the ends of the flanges b of the post. The arm d is perforated, as well as the end of the bow C, and passing through the perforations and into the post is a screw e, which confines the guard and the bow to the post. I also provide the bow C in some instances with aheadc, so as toform shoulders c', which rest against the underside of the lianges b b. When the guard Dand the bow are secured to the post by the screw, the parts are rigid, as the shoulders prevent any pivotal motion of either the guard or the bow on the screw.

While I have shown the bow provided with shoulders, it will be understood that in many instances the guard only may be provided with shoulders, as it is the slight movement of the guard in its socket that loosens the Iatented August 25, 19,03. v i.

screw, it being almost impossible to make a 'i snug it between the sides of the arm of the guardand the anges 'b' b ofthe socket, owing to the minuteness of the parte.

By forming shoulders on the arm of Vthe Y guard, which is made of Iiexible material, its

members can bev bent'and adjusted to any po-y sition after the guard is mounted on the post without the liability of straining and bending the ianges of the'post, as the pressure is resisted by the ends of the lianges instead of `the sides.

. It'vwill be understood that eyeglasses must be made of material which will not rust. Consequently they are generally made of ten and fourteen carat gold or German silver, and the flanges of the post have tobe so light in order to present a neat appearance that they will not resist the pressure necessary in adjusting the members of the guard to accommodate the nose after the parts are assembled.

In some instances I may make the shouldered head on the arm of the guard, as shown in Fig. 18, in which the shoulderse' extend rearwardly as well aslaterally, so as to bear against the body of the post, so that the lateral strain is taken by the body as well as by the anges, thus relieving the flanges of the strain.

This construction will prevent not only the lateral movement of the guard on the Y screw as a pivot, but will valso resist the strain when the guard is bent to and from the lens. The body of the guard is made as shown .clearly in'Fig. 3, having a lower member D', in the form of a scroll, connected to the arm iol by a short neck d3, and an upper member IOO jection d5. This projection, as ,well as the; j ends of the members D and D2, is perforated, so that the facingF of celluloid or other'suit# able material can be properly secured byV means of rivets to the guard when a facing is used.

By making the guard in the manner shown I am enabled to adjust it to fit noses of different contours and to adjust the lenses to any position in front of the eyes. Heretofore it has been generally necessary to provide the dealer with a series of guards, each of which can be very slightly adjusted to accomplish the result attained by my invention.

Figs. 5 to 16 are diagram views illustrating some of the positions to which my improved guard can be adjusted. The views are arranged in pairs. Figs. 5, 7, 9, 11, 13, and 15 are edge Views, and Figs. 6, 8, 10, 12, 14, and 16 are rear views. The guard can be adjusted by bending the upper and lower members forward or backward, curling the lower mermbers, twisting the neck or the upper or lower members, and moving the body portion vertically in respect to the arm, the neck allowing for this adjustment.

In Figs. 5 and 6 I have shown the guard bent to fit a nose having a shallow bridge with prominent eyes and forehead.

In Figs. 7 and 8 the guard is illustrated as bent to fit the average nose.

In Figs. 9 and lO the guard is illustrated as bent to lit a prominent nose and forehead with deep-set eyes.

In Figs. 11 and 12 the guard is illustrated as bent for use on the average nose where it is desired to lower the glasses for reading. This is done by simply curling the scroll portion D', so as to draw it up close to the point where the arm d projects from the guard, and twisting the neck d3 upward.

In Figs. 13 and 111 the lower scroll member is shown bent forward and the upper member bent back, so that the lenses will rest at an angle to the eyes for reading and close observation.

In Figs. 15 and 16 the upper member is bent forward and the lower member bent back, the lenses resting at an angle to the eyes for distance only and so that the wearer can see under the glasses.

It will be understood that other adjustment-s may be made for extreme cases; but the above will clearly illustrate the flexibility of my improved guard.

When it is desired to adjust the lenses a considerable distance from the eyes, the neck d3 may be lengthened.

It will be seen that the bearing of the guard taken as a whole is very wide, and yet the line of bearin g is comparatively narrow. The lower scroll member being open at the center forms a pocket for the flesh of the nose to enter. Thus the guard is held firmly to the nose, and the button d4 at the extreme end can be bent so as to slightly press against the nose and form a lock to prevent any pivotal movement of the glasses on the nose, and this lock also prevents the guard from sliding forward. By curving the outer edge of the upper memberDz, I increase the space between the socket and the said member and enable the upper member to firmly engage the flesh of the nose.

In Fig. 17 I have shown a modification of my invention in which shoulders d6 are shown in such position on the arm as to rest under the flanges h of the post. It will be understood that the lateral shoulders may project at any point desired so as to prevent the guard swinging on the screw as a pivot and so that the flanges will be relieved from side pressure.

I claim as my invention- 1. The combination in eyeglasses, of a lens having a post with straight flanges thereon forming a socket, with a guard having an arm mounted in the socket, lateral shoulders on the guard extending over the flanges of the post, and means for securing the guard to the post, substantially as described.

2. The combination in eyeglasses, of a lens, a post secured to the lens, straight ianges on the post forming a socket, a nose-guard having lateral shoulders, and a bow having lateral shoulders, the bow and the guard being mounted in the socket of the post, means for securing the parts to the post, and shoulders resting against the flanges forming the socket, substantially as described.

3. The combination in eyeglasses, of a post, flanges at each side of the post forming a socket, a guard having an arm, an overhanging head on the end of the arm forming lateral shoulders, said shoulders resting against the ends of the flanges of the socket, and a screw securing the guard to the post, substantially as described.

5. As a new article of manufacture, a noseguard for eyeglasses Vmade of flexible material having an arm by which it is secured to a post, and having a lower scroll member and an upper member projecting upwardly at an angle from the root of the scroll member, substantially as described.

7. As a new article of manufacture, a noseguard for eyeglasses having a lower scroll member, an upper member projecting at an angle from a point near the root of the lower member, an attaching-arm projecting from the root of said lower member, said arm having a head forming lateral shoulders, substantially as described.
