UNITED STATES PATENT OFFICE.
WILLIAM H. BOUTEILLE, OF STURBRIDGE, MASSACHUSETTS, ASSIGNOR TO AMERICAN OPTICAL COMPANY, OF SOUTI-IBBIDGE, IVIASSACHUSETTS, A. VOLUNTARY ASSOCIA- TION OF MASSACHUSETTS.
EYEGLASS GUARD.
Application led March 27, 1922. Serial N o. 547,180.
To all whom. t may concern.'
Be it known that .I, WILLIAM II. BOUTELLE, a citizen of the United States, residing at Sturbridge, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Eyeglass Guards, of which the following is a specification.
This invention relates to improvements in eyeglass guards, and has particular reference to that type of guard comprising a metal backing and a composition covering for the face of the guard.
The principal object of the present invention is'the provision of a novel and improved manner of connecting the metal and non-metallic portions of the guard, which will eliminate objectionable projecting rivets or other metallic members coming in l contact with the face, as has been customary in the past.
A further object of the present invention is the provision of an improved simplified construction which will render the manufacture of the guard much less expensive, in that it is possible to eliminate both the drawing over of the edges of the metal pad, or backing member, in the case of filled materials, and also in which the handling of small rivet members, or the like, is entirely dispensed with. c
A further object of the invention is the provision of a novel and improved construction of guard member which will have a semi-suctional holding action on theV face and therefore most firmly retain the mounting in position.
Other objects and advantages of my improved construction should be readily apparent by reference to the following specification taken in connection with the accompanying drawings, and it will be understood that I may make any modifications in the specific details of construction shown and described within the scope of the appended claims without departing from or exceeding the spirit of my invention.
Figure I is a front view of a mounting embodying my improvements.
Figure II is a face view of a guard in l which -the pad portion is constructed in accordance with my invention.
Figure III is an enlarged rear view of the pad member.
Figure IV is a similar view of the metal portion thereof.
Figure V is a sectional view as on the line V-V of Figure III.
Figure VI is a similar sectional view of a different form of plate member.
Figure VII is a view of the drawn up composition member for application thereto.
Figure VIII is a sectional view through the completed pad or guard.
Figure IX is a face view of a different shape of guard embodying my improvements.
Figure X is a perspective view of' one form of rod stock from which the pad may be produced.
Figure XI 'is a similar view of another form.
Figure XII is a plan view of a pad blank produced from Figure X.
Figure XIII is a sectional view as on the line XIII-XIII of Figure XII.
Figure XIV is a view of a further step in the process of manufacture.
Figure XV is a plan view of the structure shown in figure XIV.
Figure XVI is a view of the completed pad.
In the drawings, the numeral 1 designates the bridge of an ophthalmic mounting supporting at each end the lenses 2 and having the guard members 3 for retaining the mounting in position on the face. The invention here in question may relate either to the guard as an entirety or to the upper or what is commonly termed the pad portion thereof, the invention being more particularly illustrated in connection with the pad portion of the guard as this is the most popular present day commercial form. The pad so termed comprises a metal backing plate el, having a rivet 5 normally loosely received in the upper portion of the arm 6 Vof the guard and a facing of zylonite, celluloid, or other composition material 7, which covers the front of the guard and contacts with the face.
Prior to my invention it has been customary .to secure this facing in position through the use of rivets, or the like, thus particplarly lends itself. ,back plate l is .provided with a forwardly .turned:peripheral .edge Vor flange portion 12, rwhile the composition covering 7 is cupped v or shaped to .provide a corresponding projection with recess 1.4L at the back to re- ,eeiveitlheilange 12,projecting therebeyond in ,the portions9 adapted to be clinched down .trat-ed in :Eig-ure .Vl-Il. provides .the recess l5 which, as the guard is `appliedtothe .face,.will form a semi-vacuum producing Vmetal members contacting with the facenf l,the wearer, which has ysometimes proved ,be undesiraloleon laccount of the chemical action causedl by perspiration, or ,thelike,on the end o the rivet. An ad'- ditional disadvantage has -been that the rivet apertures, no' matter lhow well made the mounting, will in time form seats in which a verdigris deposit will take place 4rendering the mounting at once unsanitary and disagreeablein appearance. v
llt is the purpose of my invention to obviategaljl 4these defectsand this I accomplish by forming'the facing material? in cuplike formation .with ,portions 8 extending over the edges oft-he material .and portions 9 Apreferably tapered -which are bent' down and tightly clinched against Athe rear face oi the main metal ,back lplate 4.* ln this man ner the facingmaterial:retains itself in place by vits lown inherent gripping properties and atgthe lsaine vtimecovers .the edge 'l0 ofthe milll backing plate. flhis also a .feature of importance, since in prior constructions.
this edge been either partially or entirely exposed. V'lliie y.large majority ,of mouiitings of the character here referred to, it .is to be vunderstood, are `made fromwhat Vis ,gold-.filled material, or material having a base metal core and a gold filling, ,considerable care .has had lto be taken in the manufacture olii inountings of .this sort gto :properly .draw Athe goldefilled ma terial over the cut edges oi the back plate as itisstamped out. ven in` spite ofthis care, the coatingvis relatively thin on these edgesand is liable to wear or breakthrough, aga-in forming-a ,source of verdgiis and the like.
. l/Vith my invention, however, the edge may, if desired, A,belettentirely rough and unfinished., since being covered and concealed by the overturned edges of the cont,
positionmember it islentirely protected. It desired the edge maybe ystamped with the .teethserationa prongs, orthe like, 11, which bite 4vinto the,coniposition material andinore ,lirmlyliold `it ,in place `and eliminate any liability of loosening ot ythe parts vwhen Iwor-n.
Figures V1, VII, and VIII illustrate another possibility `to whichY my invention on thebackioil the backing plate,fas illus- Thisn constructio-n chamber or space, the edges at 13 Alirmly enln this form. the
gaging the flesh, which will Work up a cer-y tain amount into the pocketfl and prevent slipping, yet holding without- 'ldisc'oinfforn bit'iiigedges, or the like,V as has" frequently been necessary in the past in order toV properly retain a. mounting. Y
Figure lX illustrates affaire, view-7.0i a

lt to 'be understood that the zylonite covering member may `be formed eitherl from sheet material or-trom .rod stock, such as shown in Figure X, .or somewhat oval stock as shown'rin Figure XLwvith one side' slightly yiattened as att. In either event the rod stock is cut oft' into discs which are then milled out ,as at l17 to provide an under` cut recess to receive the metal'back plate 4, The sides of the recess, as S, are thenopened out for insertion of the pad,and at the saine tiine'the material may if desired .be stretched* as from the .round form of Figure XIII'to the ovalled form of Figure'XV. In either event the material is then vin condition .for
