Application filed November 30, 1917.

To all whom it may concern:

Be it known that I, Enmnn L. Souunnonnn, a citizen of the United States, residin ct Southbridgc, in thecu'unt of Worcester ncl State of Massachusetts, lave invented certain new and useful Improvements in Ophthalmic Mountings, of which the following is u specification.

This invention relates to improvements in ophthalmic mountings and has particular reference to a novel and improved construction of frame of what is commonly known as the \Vindsor type; that is to say, a frame having certain metallic and certain nonrnetallic portions.

One of the leading objects of the present invention is the provision of novel and improved means for readily and securely connecting the metallic and non-metallic POP- 'tions ofthe mounting.

A further object of the invention is the revision of connecting means which shall e qfiite ornamental in appearance when the mounting is viewed on the face of the wearer and which will securely retain the parts together. y

A further object of the invention is the provision of novel and improved means for detachably connecting the ends of the nonmetallic rnme member to the remainder of the mounting so that said frame member may be readily removed or replaced as desired.

Other objects and ndvnntn es of my improved construction should .pnrent by referenceto the following speci cation taken in'eonnection with the accompanying drawings, and it will be understood that I may make any modifications in the specific details of construittion shown and described within. the scope of the appended claims without departing from or exceedi-np the spirit of my invention.

' nunlification in partially :l sr-mlihil form.

Fig. XIII represents on end. vir ol' tin pa rts assembled Fig. XIV represents a fragm ntary per spective view illustrating the l'ornnuimi of the end of the non'metnllic frame member.

In the drawings I have shown spectacle mounting comprising a bridge or renter l. and suitable frames at the ends of thc bridge for retaining in position the lenses L. these frames preferably omprising the inner metallic frame member 3 and outer nonmetallic frame member 4, and employing the end piece members 5 to detnchahly connect the ends of the frunw. said. end piece members being held together as by the screws or fastening devices (3. one of which :it each end piece also serves as a pivot for a temple member 7. It is to he understood. however,

that while I have here illustruhul and par ticularly described a spectacle form of con struction, that my invention is equally applicable to eyeglasses or other desired types of mountincs.

. In that fin-m of my invention shown in detail in Figs. II, III and IV, I have illus trated as secured to or into ra l with the frame at one side the ham 8 having at its free end the offset ear 9 adopted to be secured as by the screw 10 to the adjacent end piece member, in use the non-metallic frame being placed in position around the Til metallic frame and forced down tight] therengainst, when the hand 8 is bent. an

that the'frnme is securely held in place.

In F V to VII inclusive, I have shown ii modi ed form of my invention in which. in lace of the band 8 being secured at one the metallic frame at both ends, but is of such size that the end of the non-metallic frame may be readily slipped inside the band, the non-metallic frame being prefen ably formed with a groove or channel 11 to receive the band.

After the parts have been assembled and to securely hold the band in place, I form on the end piece the offset 12 to form a seat for the taper screw 13 which is passed downward between the band and frame and as it is tightened serves to form an outward loop at the one side of the band and to tightly draw the remainder of the band around the non-metallic frame.

Figs. VIII and IX illustrate :1 nother form, in which the band 8 is fastened at the one end and is ioose at the other, the loose end being adapted to be inserted in the slot 14 of the post 15, a screw driver being inserted in the slot above the band to turn the post, which may be locked in desired ad.- justed position by tightening of the nut 16, prongs 17 on the post 'interengaging with the end piece to aid in retaining the parts in position.

In Figs. X and XI, I have shown the band in place of extending entirely around the. non-metallic frame member as formed in a substantially L-shapc attached at one end to the frame and at the other end to the end piece member, being adapted to be sprun outwardly sufficiently to allow the end 0 the frame member 4 to be pressed or sun )ped therebem ath, when it will come bac into tight engagement with the frame, preferably fitting within a suitable groove in the frame, and will suitably retain the frame in place, While being entirely invisible when the mounting is viewed from the front.

A slight variation of this construction is illustrated in Figs. XII and XIV, in that the member instead of being exactly L-shape is of angular formation and is provided at the angle with an aperture adapted to re ceive a fastening screw 18 to most securely connect the arts, in this instance likewise the member icing bent outward somewhat as indicated in. ig. XII, while the nonmetallic frame is placed in position and then bent downward into the groove It) and there secured. through the use of the screw 18.

I claim:

1. The combination with a metallic frame, of a non-metallic frame extendingtherearound, bands on the metallic frame embracing the ends of the non-mctallic frame, and means for tightening the bands for firmly securing the parts together.

2. In an ophthalmic mounting the combination with a metallic frame member, of a non-metallic frame member extending therearound, a band loosely secured to one of said frame m mbers, and means for looking the band in engagement with the other frame member for securely uniting the parts.

3. In a device of the character described, the combination with a metallic frame, and a (in-extensive non-metallic frame, of bands on the metallic fra me embracing the ends of the non-metallic frame, and means for adjusting the tension of the bands.

4. In an ophthalmic mounting, the combination with a metallic frame member, of a flexible band loosely carried thereby, a non.

' metallic frame member engaging the metal-- lic frame member,'.and means for securing the band in tight Pl'lgttgPTllBl'lb with the non metallic frame member to retainthe latter in position. i

In testimony whereof I have aflixed my signature in presence of two witnesses itncsses H. v E.
