PAINT orr cs OPHTHALMIC MOUNTING Application November 8, 1929. Serial No. 4053145 2 Claims. (01. 38 42) Thisinvention relates to an improved construction' of ophthalmic mounting; and has for its object to provide in such a mounting a bridge member formed from a length of bendable wire 5 folded into substantially U-shape and connected at its ends to a pair of spaced lens-engaging members such as eyewires or lens clamps and to also provide a pair of cooperating nose-guards each connected by a forwardly extending bendable arm to its lens-engaging member. 7 With this and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawing: Figure 1 is a front View of my improved mount- Figure 4 is a top edge View of my improved mounting.

Figure 5 shows the bridge member as connected at one end to a lens-engaging member which is herein shown as being in the form of a lens clamp.

Figure 6 shows the spaced studs as entering openings in the corresponding faces of the lens engaging members.

It is found in the practical construction of ophthalmic mountings particularly those formed of precious metal, of advantage in some instances, to form the bridge-member from a length of bendable wire and to fold this wire to form a U-shaped bridge member having elongated side arms which are adapted to be bent and when connected to the eyewires permit the eyewires to be adjusted laterally and so vary to considerable extent the pupillary distance between the lenses to fit the faces of the diiierent wearers.

Ordinarily a large number of different sizes of mountings each of a different pupillary distance must be carried in stock by the dealers to fit the different faces but by the use of my improved bridge member which is formed of bendable wire with very long side arms these arms may be bent either toward or from each other to vary to considerable extent the pupillary distance between the lenses and so eliminate to a great extent large number of the sizes heretofore carried in stock which materially reduces the investment of the dealer particularly where the mountings are formed of precious metal; and the following is a Figure 2 is a view of the bridge member as folded into substantially U-shape from a length detailed description of the present embodiment of my invention and showing one construction whereby these advantageous results may be accomplished: i

With reference to the drawing, 10 designates a pair of spaced eyewires which are usually formedL-II of precious metal and to connect these eyewires I have formed a bridge member 11 of bendable wire or material folded into substantially U-shape and providing relatively long bendable side arms 12, which arms are connected as at 13 to the eye- .1. wires 10 by solder or other suitable means.

In some instances, the ends 15 of the side arms 14 of this bridge member are enlarged, as illustrated in Figures 3, 5 and 6, by flattening or upsetting the ends of the wires to form an extended attaching surface. This surface, in some instances, may extend across a medial line thru the lenses or it may be secured in any desired position adjacent this line. On this construction, in some instances, I may form spaced attaching studs or members 16, if desired. These studs may be positioned to straddle the medial line thru the centers of the eyewires or lenses,

or they may be secured in any desired'position v adjacent said medial line. In some cases, ascl illustrated in Fig. 6, recesses may be formed in the adjacent surface of the lens-engaging members into which the studs may fit to facilitate attaching and strengthen the connection.

This bridge member is preferablyconstructedffi to lie in substantially the same plane as the eyewires and by providing these relatively long side arms, I am enabled to bend them toward or from each other so as to adjust the pupillary distance between the eyewires to considerable extent and' a'i. so reduce the number of sizes of mountings necessary to be carried in stock to fit the faces of the diiierent wearers.

In order to support this mounting in proper position upon the face of the wearer, I have pro-Iii, vided a separate set of nose-guards 17, each of which is provided with a bendable arm 18 connected at its forward end to the eyewires, whereby these arms may be adjusted independently of the adjustment of the side arms of the bridge to? properly engage the nose of the wearer and support the mounting in proper position thereon.

In some instances, the bridge member 20 may be attached to lens clamps 19, as illustrated in Figure 5 instead of to the. eyewires, as illustrated}? in Figures 1 and i.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

1. In an ophthalmic mounting, a pair of spaced metallic lens-engaging members having spaced recesses, a bridge member formed into substantially U-shape having a connecting portion and side arms of substantial length extending at substantially right angles to the connecting portion and in the plane thereof, integral elongated securing portions at theends of said arms lying in the plane of said side arms and lens-engaging members with their edges following for a substantial distance the edges of said engaging members, and spaced attaching studs on the edge of said elongated portions fitting into said spaced recesses in said lens-engaging members and secured to said members.

2. In an opthahnic mounting, a pair of spaced integral elongated securing portions at the ends of said arms lying in the plane of said side arms and said lens-engagingme'mbers with their edges following for a substantial distance the edges of said engaging members, spaced attaching studs on the edge of said elongated portions fitting into said spaced recesses in said lens-engaging members and secured to said members, and a pair of nose guards each having a forwardly extending bendable arm connected to its lens-engaging member, said bridge arms and nose guard arms being independently bendable whereby the nose guard may be adjusted independently of the bridge or the bridge may be adjusted independently of the nose guard.
