Application and October 21, 1921. Serial no. 509,238.

To all whom it iizay concem Be it known that I, STEPHEN J .Cnnnnn,

a citizen of the UnitedStates, and a resident of Attleboro, in the county of Bristol and State of Massachusetts, have invented. an Improvement in Eyeglass Constructions, of

which the following is a specification.

This invention relates to the construction I of eyeglasses. One of the objects thereofis to provide a practical construction of the above nature in which the parts are securely hold tfogether under conditions of hard use.

Another object is to provide a construction.

' of the above type in which celluloid frames are reinforced 1n a simple and dependable manner. Another object is to provide a con- 'struction of the above type'which will be inexpensive in manufacture and in which the appearance is not impaired. Ot her objects will be in part obviousand in part pointed out hereinaften';

The invention accordingly consists in the features of construction, --,1combi'nations; of elements and arrangement pf{iparts which will be exemplified in tlie structure here1nafter described and the scopeo fthe appllcation of which will be indicated in the following claims. f

-In the accompanying drawing in which is shown one of various possible embodimentsv 'of this invention,

Figure'l is a rear elevation of a pair of eyeglasses;

Figure 2 is a partial plan on a larger scale, certain parts being shown in section 1 along the line 2'-2 of Figure 5 in order to disclose the construction more clearly;

Figure 3 is. a cross-section along the line v33 of Figure 5; i

Figure 4 is a cross-section taken along the line 4-4 of Figure 5; and

Figure 5 is a vertical section taken along the line 5-5 of Figure 2 and showing the central portion of the eyeglasses.

Similar reference characters refer to similar arts throughout the several views of the drawing.

In order that a fuller understanding of this invention may behad, it may first be 7 noted that it has been attempted to mount a metallic rim member inside a celluloid eyeglass frame, that is, a framein which not ml the outer rims but bridge are of celluloi OQllStllltBblOD; Such an arrangeof the usualv heavy construction.

ment would gain certain advantages in the matter of security and strength of construction, and the avoidance'pf deformation due to shrinkage, but it has been foundfrthat there is a tendency of the metal member to snap out of the recessin which it is fitted appearance or undue cost.- As hereinillustratively set forth, there are a-numbergof elements contributing tosecurity, and it 'is to be understood-that each of these features is of independent value although a maximum ,of security is attained when;- all are employed. .It may also be noted at this point that the term eyeglasses is broadly employed to designate any device .for mounting lenses before the eyes, and that the term celluloid is used broadly throughout to denote any non-metallic material adapted for use in this relation.

Referring now in detail to Figure 1 of the drawing, there is shown an eyeglass frame comprising the celluloid rim members 10 and-11 connected by a celluloid bridge 12 which is preferably integral therewith and 4 Within the rim members 10 and 11 are respectively in suitable recesses or grooves which extend about the inner surface of the outer rims as indicated in Figure12. The outer-ends of each of the rim members 13 and 14 are connected with the usual end pieces 15 and fitted metal rim members 1.3 and 14 resting 16 to which is pivoted thetemple bar 17 of any desired construction. .The details of these latter members are not herein shown as they form in themselves no part of the present invention. It ma be notedhowever that the celluloid rim members are.

split at the outer ends of the respective" rims, terminating on the end pieces .15 and 16 and thus permitting separation to enlarge the rims when the lenses are inserted with their edges resting in the concave inner surfaces of the metal members, as shown in Figure 2.

As both'sidee of the eyeglasses are substantially scribed in detail.

identical, one only will be. de-

a metal tie"wire which is'solderecl or otherwise suitably connectecl with the. rims atits endsr and rests within a groove 2L 3) their portions adjacent the bridge with one or more lugs 18. which may ,be secured there- :to in any desired manner. These lugs are here shown as two in number and are formed of thin metal and bent mto a corrugated or s-shape, as shown in Figure 4 of the d rawing. When the metal rim member is, inserted, the celluloid is heated so as to become soft and the lugs 18 forced into the end portlOllS 0f tliebrlclgc to become firmly seated therein, in the position indicated in the drawing. These lugsthus tend toanchor the rim celluloi j g It isalso to be noted that the groove within which the inetalrims rest is deeper at the 'inits proper relation'to' 'thc surroumling .15. I I

end adjacent the*bridge as shown at 19 in Figure 2 of the drawing. This may be brought about by carrying the celluloidohtwardly toward the, center of the lens to. a

slightly greater extent at the bridge side of the rim and at the outer side, "without dc.- .tracting from the appearanceof the lens."

The'two metal- rim members 13 and 14 may alsobe'connected one with another-by formed in the rear-side'of the bridge. The

celluloid may be so shaped adjacent the endsof the bridge as to interlock-with this tic rim members adj ace'nt the dge are :wire 20. and tend to prevent it from riding out from the portions of the groove or;

i i outwardly therefrom into said non-metallic recess. a

..'When' the parts are assembled, it willthus.

be seen that however roughly theframes may be handled,the portions of the metal firmly the celluloid members in which they are seated. 1

-As' Various possible en'ibodiments might be made of the above inventlon andas various changes might be Jiiade in the embodiment above set fortln-it'isto be understood'that all matter herein set forth or shown in the ac .companying d'rst'wing to be interpreted as I i illustratme and not n a hunting sense. i

tion, a non-metallic rim member, a metal rim.

member inserted within a groove in said first rim member, an :1 projecting metal part on "said metal member extending outwardly into said non-metallic member to interlock therewith adj acent the bridge of the eyeglasses.

3. In eyeglass construction, in combination, a rim member and bridge joined thereto and both formed of non-metallic material, a metal rim member inserted within said first rim member, and a metal part secured to said metal member and extending outwardly into said non-metallic rim member djacent its point of junction with the bridge.

4. In eyeglass construction, in combina tion, a rim member and bridge joined thereto and'both formed of HOD-lliClZtIlllC material, a metal rim member inserted within said first rim member, and a metal part secured to said metal member and extending out- Wardly into said non-metallic'rim member adjacent its point of junction with the bridge, said projecting metalmember being of thin curved form.

5. Ineyeglass construction, in combination, a rim member and bridge joined thereto and both formed of non-metallic material, a metal rim member fitted within said rim member, and a plurality of projecting parts secured to said metal member and extending member adjacent the bridge.

6; In eyeglass construction, in combination,. a. rim member and a bridge joined thereto both formed of non-metallic material, and a metal rim memberresting in a groove extending about the inner side of said non-metallic rinrmember said metal rim member being adapted to snap into place in said groove and having formed integrall therewith a pair of lugs extending into and interlocking with said non-metallic material adjacent said bridge to prevent said metal rim member trom' snapping out of said groove upon bending of the eyeglasses in use. I

In testimony whereof, I have signed my name to'this specification this 29th day of September, 1921. 5 STEPHEN J. CLULEE.
