OF MASSACHU- OPHTHALMIC MOUNTING.

Patented May 9, 1922.

Application filed "November 25, 1921. Serial No. 517,722.

To all whom it may concern:

Be it known that we, ELMER L. SCHU- MAGHER and WILLIAM H. BoUrELLE, citizens of the United States, residing at Southbridge and Sturbridge, respectively, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Ophthalmic Mountings, of which the followin is a specification.

This invention re ates to improvements in ophthalmic mountings and has particular reference to what is termed a combination mounting, that is to say, amounting made up of a combination of metallic and nonmetallic parts.

One of the rincipal objects of the present invention is tl fe provision'of a novel and improved construction of frame and method of producing the same which shall cause the frame to present the appearance of an all zylonite or composition structure and at the same time possess all the advantages inherent in an all metal construction.

A further object of the present invention is the provision in a construction of this character of a novel and improved means for separably uniting the'split ends of the frame in a manner to render the joint substantially invisible and so that the continuity of the end piece or other parts will be unbroken. as viewed from the front but in which the frame may be readily opened for insertion or removal ofa lens.

A further object of the present invention is the provision of a novel and improved end ther objects and advantages of-the present invention should be readily apparent by Figure 11 represents a plan view thereof.

piece and frame connection and method. of (producing the same.

Figure III represents a fragmentary sec- Figure VI represents an end view illustrating a further step in our process.

Figure VII represents a plan view of the construction shown in Figure VI.

Figure VIII represents a view taken as on the line VIII-VIII of Figure III.

Figure IX represents a similar view showlng the member of Figure VII applied.

Figure X represents aview of a subsequent step in the process or method of manufacture.

Figure XI represents a sectional view of the complete frame as on the line XIXI of Figure II.

In the drawing, in which similar characters of reference are employed to denote corresponding parts throughout the several views, the numeral 1 designates the metallic bridge member having the central non-metallic covering 2 formed thereon and having secured to each end a metallic frame or rim member 3. One of these members 3 is provided with a slide block end piece 4 having the slot 5 formed therein tov receive the metallic butt 6 of the composition temple,

7. This block 4 is further formed centrally thereof with the recess 8 in which fits the are viewed from the'front and being retained in'position as by the screw 10.

As has been previously mentioned, the

purpose of the present invention is to provide a mounting which shall present the general appearance .of the old and well known all shell or composition frame, but with the increased advantages of \the metallic frame as well. In the accomplishment of this result we, therefore, wish to cover the metallic end piece 4 with a suitable coating of zylonite or other composition material which may be secured in place in a numher of ways, as by spraying, dipping or cementlng thereon, or more particularly and preferably by the hereinafter described method. This method consists in taking a piece of rod stock 11 of the desired composition material and centrally boring it as at 12, as indicated in Figure V The material is then flattened as in Figure VI and notched as at 13 in Figure VII. After this the blank 11 is slipped over the end piece block 4 as shown in Figure IX, the recess r and acomposition covering or rim 16 1s orrnotch 13 serving to fit up against and around the frame 3. The member 11 is then shaped by pressure, cutting, or both, to closelyconform to the block 4, and is also cut-away to provide the lip or flap 14 cor-7 responding in size and shape to the free or exposed portion of the plate 9. It will be understood that on account of the shape of the end piece block 4 the member 11 when pressed and formed therearound will closely adhere thereto and be retained in place thereon. To assist the union of the parts,= however, we preferably before placing in.

position the member 11, apply either to the interior thereof, or to the block 4, or to both, a suitable substance which will render the surface of the composition material soft or tacky and cause it to closely and tightly adhere to the block 4 and the separable block member 9. The parts having been thus secured a suitable slot as at .15 is formedin.

the member 11 to receive the temple butt 6 placed around the metallic rim 3 and secured by cement or the like, as at 17 and 18, to the 11p section 14 and the main body sect on 11 of the end piece covering, respectively. 'ThlS uniting of the end piece covering and the outer rim s'erves to securely connect .and hold the parts together, if desired the outer rim being also .ce'nented to the rim 3 to aid in uniting the parts and renderingthem more secure.

It will thus be seen that we have provided a novel and improved construction in which the end piece is covered with a zylonite coating ent1rely unbroken as viewed from the front, but in which the frame is itself split at the end piece so that by loosening of the screw 10 the same'may be opened, while tightemng of the screw 10 serves to hold downthe portions 9 and 14 and thus the ends of the metallic and non-metallic rims to the ma1n portion of the end piece with an invisible joint.

We claim: F

1 A frame of the character described com-' prising a metallic bridge and eyewire, said eye wire being split at the outer side, an end piece member carried by one end of the split eye wire and having a recess formed therein,

vtemple butt, and cutting a.

thereby, a composition covering for said rim and end piece, said end piece having a socket formed therein and a connecting member 'on the opposite end of the rim, said connecting member comprising a metallic plate adapted to fit within the socket, and a non-metallic cover portion for concealing the socket.

3. The process of forming an ophthalmic mounting consisting in shaping a metallic end piece, forming a piece of non-metallic stock with a socket, forcing the end piece into the socket and shaping the non-metallic material to conform to the end piece.

4. The process of forming an ophthalmic mounting consisting in shaping a metallic end piece, forming a piece of non-metallic stock with a socket, forcing the end piece into the socket and shaping the non-metallic material to conform to the end piece, and slotting the' shaped end piece covering to receive a temple butt.

5. The process of forming an ophthalmic mounting consisting in shap ng a metallic end piece, forming a piece of non-metallic stock with a socket, forcingthe end piece into the socket, shaping the non-metallic material to conform to the end iece, and cutting a flap from one side of t e covering to form a connecting plate receiving socket.

6. The process 0 forming an ophthalmic mounting consisting in shaping a metallic end piece, forming a piece of non-metallic stockwith a socket, forcin the end piece into the socket, shaping tie non-metallic material to conform to the end piece, slotting the shaped end piece covering to receive a ap from one side of the covering to form a connecting plate receiving socket.

7. The process of forming acomposition ophthalmic mounting consisting in forming a solid metallic end piece with a connection receiving socket, forming .a connection to'fit within the socket, applying a continuous non-metallic covering to the end piece and connecting member while within the socket,

and subsequently severing the composition covering to release the connection and attached covering therefor.

8. The process of forming a composition ophthalmic mounting consisting in forming a solid metallic end receiving socket, forming a connectlon to fit within the socket, app ying a summons piece with a connection of a. sp it non-metallic rim to the end piece covering and connection covering respectiv'ely.

In testimony whereof we have afiixed our gnatures in presence of two witnesses.
