UNITED CHARLES w. BARNABY,

OFFI E-- EYEGLASSES.

4 To all whom it may concern Be itknown that I, CHARLES lV. BARNABY, a citizen of the United States, residing at New Brighton, in the county of Richmond and State of New York, have invented certain new and useful Improvements in Eyeglasses, of .which the following is a specification. 4

My invention relates broadly to eyeglasses, spectacles or the like, and more particularly to the manner of and means for mounting therein the lens.

One of the objects of my invention is to provide such a mounting which will prevent to a greater degree than was possible heretofore the loosening of fastening screws or other connective elements.

Another object is to provide a mounting wherein the instrumentality connecting the bridge and nose-piece may rigidly and resiliently clamp the latter parts against relative displacement.

Another object is to provide a mounting of such a nature that certain elements thereof may preferably be pressed or stamped out of any desired sheet metal of the proper thickness. I

Another object is to provide in this connection a mounting for the lens which may bereadily adapted to differences in dimensions and other characteristics of the lens.

Another object is to provide a steady, accurate .and rigid mounting, and yet one which will preferably have a certain degree of resiliency.

Other objects will be in part obvious and in part pointed out hereinafter.

- To these ends, my invention, whereof I disclose herein one of the various possible embodiments, generally consists in the novel arrangement, construction, and combination of parts as hereinafter more specifically set forth and described and particularly pointed out in the claims.

Referring now to the accompanying drawing, wherein is shown the embodiment of my invention just referred to: Figure 1 is a front elevation of a portion of an eye-glass I including a formof mounting of the above type; Fig. 2 is a bottom plan view, partly broken away, of the parts shown in Fig. 1: Fig. 3 is a sectional view, on an enlarged scale, taken on the line 3-3 of Fig. 1., and looking" in the direction of the arrow; Fig. l is? arear elevation, on an enlarged scale,

Specification of Letters Patent. Patented Oct, 3 1916 Application filed October 19, 1912. Serial No. 726,692.

and partly broken away, showing the saidanother of the members constituting themounting, which member, carrying a leafspring or cushion portion 20, I hereinafter refer to as the cushion-carrying member; Fig. 8 is a front elevation of said cushioncarrying member as finally conformed.

Similar reference characters refer to similar parts throughout the several views of the drawings. Referring now particularly to the embodiment of my invention disclosed in the "drawing, 9 represents the bridge, and 10 the nose-piece. Bridge 9 is preferably provided adjacent each terminus with a transverse hole, 9, most clearly shown in Fig. 3 and nose-piece 10 is preferably provided upon its extension 10 (Fig. 1), with a transverse hole 10", most clearly shown also in said Fig. 3. Numeral 11 represents the armbearing member, provided with a plurality of arms 12 as shown, a lug 13, a plurality of spacerextensions 14, a hole '15'and a hole 16. WVith reference to the arms 12, which pillow an adjacent portion of the lens periphery, these are preferably soresiliently conformed that they will normally assume the approximate positions illustrated in Fig. 1 in dotted lines as at 12 whereby upon properly assembling the mounting their expansion around the lens periphery will tend to secure a more positive, rigid, permanent and accurate fastening. Numeral 17 represents a cushion-carrying member, provided as shown, with a lug 18, a plurality of spacer-extensions 19, a bent, preferably resilient cushion portion 20, a hole 21, a hole 22, a hole 23 and a Wall 24:, wall 24,1J eing provided with a hole 25. The holes 15, 16, 23 and25, in this embodiment, are not shown .as being tapped, while the holes ,21 and 22 por relation shown in Figs. 2 and 3 after preliminarily 1 ssembling the bridge 9, the appropriate nose-piece 10, the arm-bearmg member 11 and the cushion-carrying .meinmost clearly in Figs. 2 and 3.

her 17. As thus assembled, it will be noted that the inter-engagement of the parts in this embodiment is as follows: The face of the arm-bearing member 11 illustrated in Fig. 6 overlies the face of cushion-carrying member 17 illustrated in Fig. 8, as shown The lug 18 of cushion-carrying 'member 1'? enters the hole 9 in bridge 9, and interlocks said membe)? with bridge 9, and the formers wall 2% lies against nose-piece 10 as shown, the hole 25 (formed in said. Wall) registering with the hole 10" in said nose-piece. lhe lug 13 of arm-bearing member 11 enters said registered holes 10". and 25 and. interlocks the nose-piece l0 and the wall 2%. Spacenextensions 1d co-act with the opposed spacer-extensions 19 (see particularly Fig. 2), thereby to maintain spaced apart as shown the included portions of nose-piece 10 and bridge 9. Upon the aforesaid insertion of screw 29 the various elements will thus be positively, permanently and mutually engaged, and absolutely maintained against relative displacement or looseness. It will be noted also that there is here pres out a resilient quality with reference to the entire combination which keeps the screw 29 under tension during a considerable portion of the final turn upon its threads; thereby insuring the subjection of the said screw to such a continuous stress that the possibility of its working loose is exceedingly remote. Also, the interlocked characteristic of the inter-engagement of the parts, as pointed out, renders. impossible the twisting action, which usually arises and which would have a tendency to loosen the screw.

Ali-important feature of my invention, which should in an equivalent manner preferably distinguish every embodiment there of aimed to provide a connection between the bridge and the nose-piece of an eyeglass, resides in the fact, to be particularly noted atthis point, that the substantially alined' spacerextensions 14. define" in the arm bearing member 11 ways or grooves 32 and 33 6) that the substantially alined spacer-extensions 19 define in the cushion-carrying member 17 ways or grooves 34 and 35 (Fig. 8) of which grooves, with eye-glasses rea ers the partsin assembled relation, .grooves 32 and 34: substantially overlie each other to accommodate a shank of the bridge 9, and grooves 33 and substantially overlie each other to accommodate the shank of the nosepiece 10; and that the portion 11 of the arm-bearing member 11 and the overlying portion 17 of the cushion-carrying member 17 are naturally resilient with reference to sets up a spring-pressed frictional drag upon any accidental or other subsequent rotation of the screw, positively preventing it working loose or weakening its grip.

Upon the insertion of a lens 31 (Fig. 1), the arms 12 are forced to the position illustrated in full lines, and the screw 30 (Figs. 2 and 3) is inserted, passing freely through holes 16 and 23, and being screwed home into tapped hole 22. It will thus be seen that the lens is held against displacement or looseness within its general plane, and also laterally ofsaid plane. It will also be apparent that by thus mounting the lens between the elements described, which I may call spring-cushioning elements, any likelihood of the lens being broken when subject ed to sudden shock or strain, as when the are accidentally dropped, is avoided. An advantageous adaptability of this embodiment to variations in nose-guard, bridge and lens dimensions, and to variations in locations of the drillings therein, should also be apparent.

I desire to call attention to the fact that 1- preferably give to the arm-bearing memher a cupped portion 26, adjacent the hole 16, best illustrated, with reference to its clamping function, in assembled relation in Figs. 1, 2 and 3. This cupped portion is an important feature of-this embodiment of my invention, because it adds extra gripping eliiciency to the lens-holding parts. It

should be noted also that in the present emmation and denominated in the: manner disclosed herein merely for illustrative purthe lens will be so gripped.

It should be obvious that my invention may be advantageously utilized in connection with eye-glasses of the kind generally known as spectacles.

Various other modifications and changes in the design and construction of my improved mounting could be resorted to, also,

without departing from the spirit of the invention or sacrificing any of its advantages.

Inasmuch as many changes could be made in the above construction, and many apparently widely different embodiments of my invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be taken as illustrative and not in a limiting sense. It is also to be understood that the language used in'the following claims is-intended to cover all the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
