Sept. 15, 1931. H. KATZ OPHTHALMIC MOUNTING Filed May 20, 1926 R. Y 1H .T W1 M Patented Sept. 15, 1931 PATENT- OFFICE HERMAN KAIIZ, 0F OAKLAND, CALIFORNIA OPHTHALMIC irounrme Application filed May 20,

My invention relates to an ophthalmlc mounting, and'particularly to the nose rests thereon.

An object of the invention is to provide an ophthalmic frame having nose-guards which are formed integral .with the lens rings and may be readily adjusted whereby the frame may be fitted to practically any size or shape of nose and without altering the pupillar distance of the rings.

Another 0 'ect of the invention is to provide a mounting with the foregoing advantages in which the entire frame including the rings and rests may be formed as a single integral unit.

A furtherfeature of the invention is in the provision of nose-rests of the character described which may be incorporated with mountings both of the type in which the bridge is arranged to set upon the nose and the type in which the bridge merely spans the nose.

A still further object of the invention is to provide means for reinforcing'the rests and the attachment between the same and the rings, which will be entirely concealed within such members.

The invention possesses other objectsand features of advantage, some of whlch, with the foregoing, will be set forth in the following description of the preferred form of my invention which is illustrated in the drawings accompanying, and forming part of the specification It is to be understood that I do not limit myself to the showing made by the said drawings and description,

' as I may adoptvariations of the preferred form within the scope of my invention as set forth in the claims.

Referringto said drawings: Figure l is a rear elevation of an ophthalmic mounting constructed in accordance with my invention.

Figure'2 is a plan view of the mounting. Figure 3 is a vertical section view of the mounting taken on the line 3-3 of Figure 1.

Figures 4 and 5 are viewssimilar to Fig

ures

1 and 3, except that the rests are shown embodied in a mounting in which the bridge.

is of the type arranged merely tospan the nose.

As illustrated in the drawings, the mounting comprises a frame 2 which includes a pair of

rings

3 and 4 and a bridge 5.: The frame, or at least the portion comprising the rings 3, is preferably formed of cellulose composition, and, as here shown, the entire frame is constructed as a single integral member. Suitable temples 6 are preferably hinged'to the rings at opposite ends of the frame.

Preferably formed of cellulose composition, and here shown as an integral art of the frame, are nose-rests 7 and 8 which are respectively associated with and extend from the

rings

3 and 4. The base portions 9 of the rests project from the rings transversely of the plane of the frame and rearwardly therefrom, and the rests as a whole extend upwardly in more or less concentric relation with the associated rings. The base portions 9and head portions 12 of the rests are preferably widened in a direction transversely of the frame so as to, provide increased nose engaging surfaces for the rests, in the present form of the invention the widening of the head portions being accomplished by bending the upper extremities forwardly of the frame.

In fitting the frames to the wearer, the rests may be adjusted by bending same at their point of connection with the rings or any portion of their length. In this way a maximum amount of adjustment is available without entailing a change in the upillary distance of the frame.-

permit of repeated and extreme variations in the adjustment of the rests, I provide means for reenforcing the rests throughout their length and at; their point of connection with the rings. As here shown'there is embedded in each rest a wire 13 which is preferably flexible and formed of metal. The wire 13 it will be noted extends the full length of the rests and extends into and is embedded in the associated ring. The reenforcement for each of the rests may be In or or to insure the rigidity'of the rests, particularly when the adjustment has been made, and to 5 bination with a frame including) separate as shown in Figures 1 and 3 or it ma be formed as one continuous member 14 a which extends through the bridge, as shown in Figures 4 and 5.

It will now be evident that the rests may be adjusted to be positioned almost any manner desired. First the rests may be adjusted perpendicularlyto the plane of the frame; second, they may be adjusted co- 'planar to the frame, and third, each rest may be twisted about is own axis so that the head ortion as well as all the other portions of tide rests may lie flat against the nose.

In the embodiment illustrated in Figures 15 4 and 5, the bridge is of the t arranged to merely an t e nose, and t e rests are therefore a apted to receive the full weight of the mounting. The rests of my invention are particularly advanta cone in this arra ement, since they may so formed and a justed as to lie at the front or rear of the frame or exactly between the rings.

I claim:

1. In an ophthalmic mounting, the comlens rings of cellulose composition and a ridge connecting said rings to ether, nose-rests of cellulose com osition ormed integral with said rin an metal reinforcing means embedded 1n said rests and extending. therefrom and embedded in said rings.

2. In an ophthalmic mountin the combination with a frame including Iens rings of cellulose composition and a bridge connecta; ing said together, a nose-rest of cellulose materia formed integral with each ring and extending transversely and upwardly therefrom at its point of connection there-.

with, the upper rtion of said rests being 40 formed to provid d a nose bearing surface 0 larger area transversely of the frame than that of the lower portion of the rests, and a flexible reinforcing member embedded in said and rests and extending respectively t erein substantially concentric and longitudinall 3, In an ophthalmic mountin nation with a-frame inclu ens supportmg portions of non-metallic composition and a bridge connecting said portions to-.

gether, a nose rest of non metallic compositionformed integral with each portion and extending transversely and {upwardly thereand a flexible metal reinforcing member embedded in said portions and me and eitending respectively thereinsubstantially concentric and longitudinally.

6 4. In sniophthalmic mounting, a frameof non-metallic composition including lens holding portions, nose rests formed in said portions and adapted to be bent n to variously shape and dispose the bearing ee portions offthe'reste, and metallic reinforcfrom at its point of connection therewith,
