is a specification.

This invention relates to improvements in ophthalmic mountings, and has for its object to provide a non-metallic rim for embracing the eyewire of the mounting, which rim is grooved internally to receive the eyewire, the stock of the rim on one of the side edges of the groove being less than that of the opposite side thereof to facilitate snapping the rim over the wire after the ends of the rim are secured to the wire. I

With these and other objects in view, the invention consists ,oI certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims. In the accompanying drawlngsz Figure I is. a front elevation illustrating an eyeglass mounting of my improved construction and showing the ends of the nonmetallic rim as being-secured to the eyewire at points adjacent the end pieces of the wire.

Figure 2-shows a portion of the non-noetallic rim as broken away and illustrating the rivets forsecuring its ends to the eye wire as set on an angle to the diametrical axis of the lens through the eye-wire.

Figure 3 is an enlarged transverse section through the eye wire showingthe nominetallic rim as being formed thinner on oneedge than on the other to facilitate its being snapped over the metal eye-wire after its ends have been secured thereto.

Figure 4 is an edge view illustrating the non-metallic rim as having been secured at its ends to the eye-wire, the body portion of the rim being in position to be snapped over the eye-wire.

l fith reference to the drawings, designates the eye-wiresoi an ophthalmic or eyeglass mounting, which are connected together by a bridge 11, and the ends of each oi the eyewires are provided with end pieces 12 through which the ends of the wire are connected in the usual way about the lens and which end pieces also serve as the connection for the temples l3.

'Ihe eye-wire '10 is designed to be covered or lnclosed by a non-metallic rim ll which may be made of any suitable material such as celluloid, zylonite or other material.

In order to connect this non-metallic rim to the eye-wire and have the same tight and firm on the wire I first cut the rim to exactly' the right length to fit tightly upon the wire and then attach theend portions 15 of the rim to the eye-wire at points adjacent the end pieces by means of rivets or pins 16 while the rim is set at an angle to the wire in the position illustrated in Figure 4. I then force or crowd this rim inwardly and finally snap it over the eye-wire to fit closely around the same.

, In order to cause this rim to spring outwardlynx and yield sufiiciently to be snapped overt e eye-wire I preferably'form the inner edge 17 of this rim considerably thinner than the opposite or outer edge 18 thereof so that upon forcing therim over the wire the thin edge will stretch and yield suiticiently to permit the rim to be snapped into position. i

In some instances it is found desirable instead of passing rivets or pins 16- radially through the ends of the rim, to set these rivets or pins on an angle asbest illustrated in Figure 2, inclined towards the end pieces whereby they are adapted to offer the maxi- .mum resistance to the strain incident to snapping the run over the wire and so firmly retain the ends of the rim to abut closely against the end pieces 12. By my improved construction, these rims may be readily positioned on the eye-wire and when so positioned fully cover the eyewire particularly when observed from the front oi the mounting; The foregoing description is directed solely towards the construction illustrated,

hut I desire it to he understood that I re- Milli cove being ofiset from a medial line through the rim, and the ends of. said rim being secured adjacent said end pieces. 2. An eyeglass mounting. comprising a pair of metallic eye-wires connected by a 5 bridge, end pieces at the opposite ends of each of said Wires for connecting the ends of the Wire, a non-metallic rim embracing the eye-Wire grooved internally to receive
