Specification of Letters Patent.

Patented Dec. 10, .1907.

Application filed April 16. 1906. Serial No. 311.876.

T 0 all whom it may concern:

Be it known that we, JESSE M. WEBSTER and CAR-L F. INGoLD, both citizens of the United States, and residents of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Eyeglasses and we do hereby declare that the following is a full, clear, and exact description thereof.

Our invention relates iarticularly to nosepieces for eye-glasses an has for its object to improve on what is set forth in Patent 628930, granted July 18, 1899, said invention consisting in what is herein shown, described and claimedf Figure 1 of the accompanying drawings represents a partly sectional rear elevation of one of our improved nose-pieces for eye glasses on an enlarged scale and in connec tion with fragments of lenses; Fig. 2, a nose side elevation of a portion of the device, the bridge of the same being in transverse section; Fig. 3, a perspective view of one of the pivotal guards of the device in connection with an arm having a spring extensionby which the guard is controlled, and Fig. 4, a sectional view on the plane indicated by line 44 in Fig. 3.

Referring by letter to the drawings, A in dicates an ordinary spring-bow bridge, the ends of which are engaged with studs B attached to lenses C direct or constituting parts of frames for the lenses, as is common in the art. Each end of the bridge A is secured,

.in connection with a stud B, by a screw D,

and this screw also serves to hold the folded end of an arm E in engagement with the stud. The arm is of suitable curvature and a narrow outer portion E thereof is a spring parallel to the remainder of said arm and having yield transversely of the same from a point adjacent to the screw D by which, an end of the bridge A and the folded portion of the aforesaid arm are held in engagement witha lens or lens-frame Stud. The lower end of the spring-extension E of the arm E is connected, by a rivet F with a guard G, and the rivet has play in a slot H with which said arm is provided. The lower end of the guard is preferably folded on that of the arm and a rivet I constitutes a pivotal connection between said guard and stiff portion of said arm.

The construction and arrangement of parts, as thus far described, is such that the guards G of the nose piece normally project, for the most part, in rear of the remainder of said nose-piece, and are designed to support the eyeglasses in an easy and comfortableposition on the nose of the erson wearing same, the necessary pressure being exerted by the bridge A aforesaid. When the eyeglasses are not in use the guards may be swung on their pivots I, against resistance of the springextensions E of the arms E, so that the upper ends of said guards will lie approximately within the plane of the lenses to economize space in an eyeglass case, the same as in the patent aforesaid, the particularfeaturcs of our improvements being said arms having the slots H and said spring-extensions, and the rivets F that play in the arm-slots and connect the aforesaid arm-extensions with the guards G that are in pivotal connection with the lower ends of the stiff portions of said arms.

Each guard G is preferably extended to lit up under the orbital arch ofthe wearer of the eyeglasses to thereby increase the bearingsurface, relieve pressure on the nose and prevent tipping of said eyeglasses, their hold on the wearer being very much better than is ordinarily the case. The guards are also preferably apertured, to provide for better hold of same on the nose and under the orbital arch, the nose-aperture of each being a reverse curve and of preferably greatest area at the upper end, this reverse curve of the aperture serving to insure against tipping of the eyeglasses when in use. It is also preferable to make the longitudinal edges of each guard G concavo-oonvex in contour approximately parallel to the edges of the reversed curve nose-apertures in said guard, this construction serving to obtain clearance for the inner canthus of the eye and to obtain bearing on the nose of the wearer of the eye-glasses where pressure will be the least objectionable.

Thearms, their spring extensions and the guards being preferably of thin material, the pressure of the eyeglasses upon the nose of the wearer is elastic and said guards are in a measure self adjusting and thus automatically conformable to said nose, their connection with said arms being such that they have ready yield in one direction under pressure instead of being distorted.

We claim 1. The combination with the studs of eyeglass lenses 0r frames of same, the spring-bow bridge-piece, slotted arms each having a fold held with an end of said bridge-piece in engagement with one of said studs, the outer portion of each arm being a spring; a noseguard in pivotal connection with the lower stiff portion of each arm, and a spring-andguard'connecting rivet having play in the slot with which the stifi portion of the arm is provided.

2. The combination of the eyeglass studs, the spring-bow bridge-piece, slotted arms each having a fold held with an end of said bridge piece in engagement with one of said studs, the outer portion of each arm being a spring; a nose-guard in pivotal connection with the lower stiff portion of each arm and having a reverse curve aperture lon itudinally thereof as well as concavo-convex longitudinal edges approximately parallel to the edges of said aperture, and a spring-and-guard connecting the spring-bow brid e-piece, slotted arms each having a fold he d with an end of said bridge-piece in engagement with one of said studs, the outer portion of each arm being a spring; a nose-guardin pivotal connection with the lower stiff portion of each arm and extended to fit up under the orbital arch of the wearer of the glasses; and a spring-andguard connecting rivet having play in the slot with which the stiff portion of each arm is provided.

In testimony that we claim the foregoing we have hereunto set our hands at Milwaukee in the county of Milwaukee and State of Wisconsin in the presence of two witnesses.
