71: all tI'li-om. it may concern.

u it known that I. (it s'rtv lunru. a lttzen ol' the l'ntled States. and re ident luiprovenn-nt in l'lyeg'hnsot aha-h the lollowing i a The ohjeet ot' the pre ent intention is to n'mhu'e a mounting in \\hh'h the lens elips, en stra and body are :ill rompriseil in a single integral pieer. whereby the eonstruetion is ehezqwned. lightened and strengthened and the liability to loosene s or tlliilt'lllllllll ot' the parts is avoided.

To the above end I propo e to form my mounting of a single tint blank eomprising he seieral part referred to. this blank bein; formed and bent in the manner herellltll'l ll'l ilesi'l'ilu-il In lit-mill t the desired re- .a In the aeeoiopauyiing drawings: Figure l s a side elevat on of the sheet-metal blank to llat eomlition: Fig. 2 is a side elevation of the blank alter the body portion has been partially bent to U-sha ie; Fig. 3 is a seetlen on the line 3--3 of ldg. 2: Fig. 4 is a side elevation of the blank after the bending of the. body portion has been completed; *ig. 5 is a section on the line -5 in Fig. I: Fig. is a section similar to Fig, 5 after the mounting has been further formed by bending in the lens clips and the lens straps; and Fig. 'i' is a front elevation of the mounting as applied to a lens.

As shown in Fig. l the blank from whieh my improved mountingis made isl'ol'lllt'tl by a suitable pom-hing operation from tlat sheet metal of the thickness necessary to prmlaee lens clips and lens straps of suitable stillness. 'lhis blank comprises, in its flat. form, a longitudiniil central straight llurtiun whieh 'ultimately forms both the only portion of the mounting and tho lens straps. The part whieh forms the bodyportion is designated by the reference number l and it extends to and between the ltttu'ttll'tpoints 2 2. At each side of the longitudinal 'l'lllt't' llu' body-portion 1 has an enlargi-munl l ha-h is mrforated t0 reeeive the post. or pivot on whieh the nose- 'rip lever swings.

The lens straps are formed of the terminal l tll'llUlla ti of the straight middle portion of the blank. these terminal portions extending from the junctureqmints l to the longitudinal extremities of the blank.

The lens elips are formed of two generally-eireular portions 7 of the blank, which are ubsequently perf rated for attachment to the lens. and whieh lie on opposite sides of the hodymrtion l. 'l'hese port ionsv i are separated from the holy-portion 1 by punt-lung out the intermediate metal. but they are each connected with the juncturepoints 2 by two narrow arms S-'-8 extending to these points. respm'tirely.

The blank of F ig. 1 is converted into the final form of the mounting by bending operations alone. which may be performed by means of suitable bending dies. The first operation, which may be performed in two stages, t'olisists in bending the body Mon 1 out. of the plane of the blank and into U- shape. The firststage of this operation is illustrated in Figs. 2 and 3. As this bending of the body portion involves the shortening of the longitudinal median portion of the blank inthe direction of the original plane of the blank, the juncture points 2 are coarms 8 are thus bent toward each other.

The second sta of the bending tigerntion is illustrateti in Figs. 4 and 5. on the body rtion has been bent to its final form. whil the arms 8 have been brought ttlifithcr so far as to be substantially para e The laststep in the bending of the mounting, which maybe performed by a single die operation, consists in curving the lens straps inward to fit the curved edge of the lens and bendi the lens clips inward and into'substantial y parallel position to embrace, the lens, as illustrated in Figs. 6 an The mounting above described is completed by perforating the lens clips to recoive the screw 12 by which they are secured .to the lens 9 in the ordinary manner, and is then soldered to a rigid yoke 10. It is particularly useful in the t pa of eyeglasses in which the nose-gal. s are mounted on pivoted spring-pressed lovers. The form 0 blank and mode of construction mcidently drawn nearer together and the above doscribt'd malt -lll the ptlxluoliou of a slot ll, extending from tho 'norr (lid of the body portion to tho'h'ns .li is. and this slot. not only scrnrt's a construction of light weight and of rtmsidornhlo slillm'sn in proportion to tho wright, but it also may ln' ntililed as a mm in which the now-guard lover may he pivoted. Tln' mounting is not limited to use in mnnt'ction with this form of mechanism, however, as the body may be utilized as 1 int of attachment of any desired form 0 nose-clamp mechanism. claim: 1. An e e-glass mounting consisting in an ntegral oat-metal m tbcr, comprising a -shlpcd portion constituting a body, with an upper and a lower portion in which the sheet-metal has in horizontal plaucs, two

lens clips, and two arms connccting cat-h h'ns.

clip with said upper and lower portions, rclpcctively the sheet-metal in the lens-clips and arms lyin in vertical planes.

2. An eye ass mounting consisting in a single integral member comprising a. body portion, lens clips, and lens straps, the momi lu-r bring providvd with a nn-dian horizontal slot extending from arm the innrr and of the body portion to tho Ions rli is, and an arm axtoading from rarh ions r ip to t'tlt'll Ions strap.

3. An vyvglms mounting c nsisting in n singh intrgral sin-M nu-tal nu-mln'r comprising a portion douhlrd to form a body with an uppt'r and a lower arm, h-ns straps oxtcnding upwardly and downwardly from the arms. rvs otiwly. and two lens clips. each h-ns oli wing connected with each of said arms 0 the body by an arm extending from tho lens clip to the body.

4. A blank for an ovoglass mounting comprising a longitudimtl central straight: portion. and two scparated portions, one on each sido of said rrnlral portion, both of 'lllt'll arc t'llllllt't'lttl at tho samo point with oat-h 0nd of said m-ntrnl mrtion at corrcqmnding ilistalu't's from saitl t'lltlrl.
